Answer: Using a Venn diagram, the character trait of personality belongs shared between heredity and environment, since it is influenced and shaped by both.
Explanation:
Hereditary and environmental factors (directly and indirectly) influence, shape, and change personality traits throughout a person's life in a number of ways. Our hereditary influences prior to adulthood include social classes, parental involvement, religion, social interactions, family presence and values, sibling relationships, education, role models, encouragement, punishment, and morals. After we mature as adults and begin our individual journey, our environments, and surroundings influence our experiences and imbue our personality with new perspectives and values. Those environmental factors may include office politics, colleague relationships, legal accountability, independence, financial responsibilities, personal survival, building a family, commitments, setting objectives, and meeting our own needs. Based on these various factors, we can conclude that personality traits are influenced equally by heredity and environment as we progress and mature throughout our life.

11Certain types of plants have flowers that secrete nectar, a sweet liquid that attracts animals such as bats. The bats visit these flowersand feed off of the sweet nectar. As they feed, they pick up pollen and spread it to other flowers. What effect do bats have on theseflowering plants?OA. Bats increase the plants' population.OB. Bats decrease the plants population.OC. Bats prevent the plants from reproducing.OD. Bats prevent the plants from growing tall.ResetSubmit
Bats, in this case, are acting as pollinators, which means that move pollen from flower to flower favoring outcrossing and fertilization of the flower, this way fruits and seeds are produced, therefore we can say that the correct answer is option A.
which possible mutation of the DNA triplet GAC will affect the production of a protein by the gene that contains this triplet
To answer this question we need to look at the genetic code to see what amino acid GAC triplet codes.
As is in DNA we need to pass it to RNA
GAC = CUG = Leu
Now we have four possible options, so we need to obtain the RNA triplet and look at the genetic code so we can see what each code.
A.- ATC = UAG = Stop
B.- AAC = UUG = Leu
C.- GAT = CUA = Leu
D.- GAA = CUU = Leu
So options B to D all code for leucine, the same amino acid as the original triplet, meanwhile option A does not code for another triplet but is a Stop codon, meaning that protein production will stop there, so the correct answer is option A as a premature stop definitely will leave the protein unfinished and with no function or defective.

Extra fertilizer in water can cause algae to reproduce and bloom out of control. What type of interaction in the Earth system is this?A. Hydrosphere-LithosphereB. Atmosphere-LithosphereC. Atmosphere-BiosphereD. Hydrosphere-Biosphere
There are five systems, or strata in this classification on Earth, geosphere (comprises the interior and surface of rocks, here it has its own distinctions, such as lithosphere as the solid outer part of the earth), biosphere (the life-supporting stratum of the earth), hydrosphere (comprises the water bodies), atmosphere (the gas envelope of the planet, it has its own strata), and cryosphere (the ice reservoirs of the planet). With this information, we can proceed to analyze the possible options.
A. Hydrosphere-Lithosphere: interaction between the water bodies with the outer earth layer, there is no life-supporting system, so is incorrect.
B. Atmosphere-Lithosphere: Interaction between the gas envelope and outer earth layer, there are no water bodies so it is incorrect.
C. Atmosphere-Biosphere: Interaction between the gas envelope and life-supporting system, there are no water bodies so it is incorrect.
D. Hydrosphere-Biosphere: Interaction between the water bodies and life-supporting system, this is the correct answer, it has the water bodies where algae can bloom and the life-supporting elements of the biosphere that allow these organisms to survive.
Which sentence best explains the relationship between a community and an ecosystem?
OA. A community includes both an ecosystem and the surrounding biotic factors.
OB. An ecosystem includes both a community and the surrounding abiotic factors.
OC. A community can contain multiple ecosystems.
D. An ecosystem can include communities from different regions.
Answer: B. An ecosystem includes both a community and the surrounding abiotic factors.
Explanation: An ecosystem includes both a community and the surrounding abiotic factors. An ecosystem comprises living organisms that reside in a particular habitat alongside non-living components of that environment, such as air, water, and soil. A community is the population of diverse species that live in the same area and interact with one another. The relationship between an ecosystem and a community is that an ecosystem includes both a community and the surrounding abiotic factors. The abiotic components of the ecosystem influence the survival and interactions of the biotic components, including species interactions and nutrient cycling. Therefore, an ecosystem's biotic components interact with the abiotic environment, and an ecosystem cannot be complete without the interaction of living and non-living things.
Why does DMD affect mostly boys? Use CER.Group of answer choicesA. DMD must be a sex-linked disorder. For example hemophilia is a sex-linked disorder that affected mostly males due to being located on the X chromosome. For females to be affected, they would have to have both X-chromosomes affected, since they have 2.B. DMD does not affect mostly boys. There is not way to determine is males are affected more the females.C. DMD must be a autosomal-linked disorder. For example Huntington's is a autosomal-linked disorder that affected mostly males. For females to be affected, they would have to have both X-chromosomes affected, since they have 2.
Duchenne MD is caused by a dystrophin gene in the X chromosome. Boys only have one X chromosome making the DMD more present in the boys, as the girls can almost always balance the chromosomic anomaly with the second X chromosome. That's the case with hemophilia that is also a sex-linked disorder. Being the answer to the question the letter A.
Which of the following would be most effective at reflecting sunlight from earth's surface?A. dark-colored parking lotB. snow-covered fieldC. forestD. jungle
In this case, we have that darker colors absorb light and lighter colors reflect it, in earth's case we have an effect called albedo, which implies, the amount of light that the planet surface reflects back, the poles are the areas that reflect most of this energy and therefore highly important for earth's temperature/radiation regulation. Therefore taking this into account we can say that the correct answer is option B.

The release of oxytocin during labor stimulates muscle contractions that push the baby through the canal. It is a feedback loop that results in a change in the body's status, instead of resulting in a return to homeostasis. When there is a change in body status, the feedback is a positive feedback loop.
How are plants influenced by human societies?
Answer:
Explanation:
Plants are affected both positively and negatively by human societies. We either help their growth, or stunt their growth. For instance, we may add fertilizers to the soil. This helps plants, or we may cause oil spillag on soil, which in turn kills plants.
how are adaptations related to the ecosystem where an organism lives?
Adaptation relates to the ecosystem of organisms because organisms must adapt to the changing biotic and abiotic factors in their ecosystems.
Adaption and ecosystemsAdaptation refers to the adjustment of living organisms to the changing factors in their environment in order to continue surviving in the environment.
Ecosystems, on the other hand, refers to communities of different organisms interacting together and their physical environments to form a system.
Thus, an ecosystem consists of both living and nonliving components. The living components include other living organisms of the same or different species. The non-living components include edaphic or soil factors, rocks, and climatic factors such as temperature, pressure, salinity, precipitation, etc.
An organism living in a particular ecosystem must be constantly adapting to both living and non-living factors of the ecosystem. Such an organism must be able to compete with other organisms of the same or different species for resources.
The organism must also be able to adapt to changing abiotic factors in other to continue surviving in such an ecosystem.

Which of the following can be determined from hair without the follicular tag? Mark all that apply!
Group of answer choices
what part of the body
species
race
age
sex
Mitochondrial DNA analysis is feasible if no follicular tag is visible. A person's mother's genetic material is the only genetic material that can be identified by mitochondrial DNA analysis. Therefore, species and race are the proper answers. A microscopic study of hair lacking a follicular tag cannot detect age and sex reliably.
The follicular tag, which is a rich source of mitochondrial DNA and can be used to identify a person, may remain present if the hair has been forcibly removed. If mtDNA can be retrieved from a hair with a follicular tag, it can be used as individual proof. The tissue from a hair follicle that is still affixed to the root end of a hair is called a follicular tag. In a medullary appearance known as a fragmented medulla, the proportion of the medulla that is visible is lower than the part of the medulla that is not.
Thus, we can state that mitochondrial D.N.A. analysis is possible in the absence of a follicular tag.

helpppp please ecosystem between 1975 and 1976 after which time rapiddeforestation and logging took place. Starting in 1979 the localpeople became concerned that the native finch population haddeclined drastically and began replanting mature trees in the area atwhich point the finch population then grew to levels seen in1975-1976. Which of the following explanations is the most crediblegiven the changes in the finch population?
Since the population of finches had decreased when deforestation and logging started, and it returned to its original values prior to deforestation when locals started to replating trees, it follows from these facts that trees are being a limiting factor in finches' populations, either because they're acting as niches, food, both or anything else that these populations needed to survive.

Explain the difference and similarities of the chromosomes in a cell at metaphase mitosis and in a cell at metaphase 2 of mitosis 2.
Question: Explain the difference and similarities of the chromosomes in a cell at metaphase of MITOSIS and in a cell at metaphase 2 of MEIOSIS?
Explanation:
In the metaphase of mitosis, chromosomes line up at the equatorial plate at the centromere, which joins sister (identical) chromatids. In metaphase I of meiosis, they are aligned at the equatorial plate by the chiasmata that join the tetrads, already recombined. Thus, in metaphase II of meiosis, the sister chromatids are genetically distinct because of crossing over in meiosis I during prophase 1.
Answer:
Similarities in the chromosomes between metaphase of Mitosis and Metaphase 2 of Meiosis:
In metaphase II of meiosis and metaphase of mitosis, chromosomes line up along the metaphase plate due to the action of microtubule spindle fibers emanating from the centrosomes located at opposite cell poles. These fibers are attached to the chromosomes by kinetochores at the centromeres of the chromosomes.
The chromosomes are similar in that each is composed of two sister chromatids and the individual chromosomes are positioned similarly on the metaphase plate.
Differences in the chromosomes between metaphase of Mitosis and Metaphase 2 of Meiosis:
The chromosome differs in that in a mitotically dividing cell, sister chromatids of each chromosome are genetically identical, but in a meiotically dividing cell, sister chromatids are genetically distinct because of crossing over in meiosis I. Moreover, the number of chromosomes at the equatorial plate in meiosis II is half the number in the mitotic nucleus.
In metaphase II the chromosomes are aligned at the center of the cell. This time there are no homologous chromosomes to be paired with.
In mitosis, the sister chromatids that make up a given chromosome are identical. In meiosis II, they may differ in length if they participate in crossing over during prophase I. The chromosomes then differ in length when they reach metaphase II.
how does the myelin sheath affect the transmission of an action potential (2 marks)
Solution:
Myelin is arranged in several layers around the axon of neurons, generating what is called the myelin sheath. The function of myelin is to accelerate the conduction of nerve impulses, allowing more rapid transmission of the membrane action potential.
Consider the following diagram:
Review the structure of leaves and the chambers through which gasses move. Why is there air surrounding the mesophyll (spongy) cells inside the leaf?
The spongy mesophyll contains very few chloroplasts and it has a large surface area in order to increase the diffusion of carbon dioxide and oxygen. There is an intercellular air space within the spongy mesophyll layer which also allows the diffusion of carbon dioxide and oxygen. The air spaces are connected to the stomata. Stomata is a porelike opening in the underside of the leaf that allows carbon dioxide and oxygen to diffuse into and out of the leaf.
Is the cell an open or closed system? Explain youranswer using at least one example of a cellorganelle and its function
The cell is an open system. The cell membrane could help us to clarify this. The cell membrane is semipermeable, that is, it allows the entrance
of certain molecules, usually small molecules. Nevertheless it has strategies to allow the entrance of bigger molecules, like its recognition with
its membrane receptors. With these features, the cell interacts actively with its environment, showing it is an open system.
