Meanwhile I will post the next question: A woman with blood type A and a man with blood type B have 3 children one each with blood types A,B and O . What are the genotypes of the parents

Answer: A. Store genetic information in nucleic acids.

Explanation:

Cells store genetic information in the form of DNA while viruses typically store their genetic information in the form of RNA and sometimes DNA.

In the northwest, we can expect the warmest weather.

A weather map, also known as a synoptic weather chart, depicts various meteorological features across a certain area at a specific time and contains many symbols with various meanings. Since the middle of the 19th century, these maps have been utilized for research and weather forecasting.

Isothermal maps display temperature gradients that can be used to identify weather fronts. Frontal zones first appeared on weather maps in Norway in the 1910s. Jacob is credited with developing the polar front idea, which was based on a network of monitoring sites along the Norwegian coast during World War I.

The molecule in charge of storing and passing to the offspring the genetic information is the nucleic acid DNA, deoxyribonucleic acid (option B).

Answer:

Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.

Explanation:

Biodiversity has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution, and climate change.

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.

At least, we need to be aware of all the factors that contribute to this:

Humans depend upon biodiversity for survival, such as for the foods we eat, medicines we use to stay healthy, and materials we wear or use to build our homes. These services are the tangible products or items that we and other species consume for survival. human beings have to survive a lot for these resources if biodiversity o our planet earth is facing any such serious threat.

An organism that is multicellular with cell walls and absorbs nutrients from decaying organic matter is referred to as Fungi. It belongs to the Kingdom Fungi

- All of these choices are correct.

Lipids are organic compounds that are mainly used to store energy, nonetheless, they have other important roles. Depending on their structure, they can be part of cell membranes (phospholipids) carry messages (cycloperhydrophenanthrene derivates), and so on.

The alternative that best explains the change in the frequency of penicillin resistence in S. aureus is:

D) S. aureus that were resistant to penicillin survived and reproduced in the presence of the antibiotic, while nonresident strains did not.

The bacteria strain resistance to a antibiotic melecule is a case of the ability to defeat the drug by the process of adaptation to the substance. When a organisms is exposed to a antibiotic for a long time it will adapt to survive, since artificial selection will take place by the pressure of the drug in the environment, being the bacteria that can survive and reproduce able to make everytime more resistant offspring.

- Biotic factors are living organisms that take part in an environment, for example, plants and animals are biotic factors.

- Abiotic factors are all non-living parts of an environment, for example, the temperature, the soil, the sunlight, etc.

The shell is the part of a living organism, so it can be classified as a biotic factor.

A reptile is an animal member of the class Reptilia, they can be classified as biotic factors.

The sea turtle is a living organism, so it can be classified as a biotic factor.

The temperature is a non-living part of the environment, it can be classified as an abiotic factor.

The substrate is the base where living organisms live, for example, the bottom of the marine habitats formed by rocks, sand, or gravel), it can be classified as an abiotic factor.

Detritivores are organisms that feed on dead organisms and decomposed matter, they can be classified as biotic organisms.

Answer:

the sediments get progressively thicker

Explanation:

Near mid-ocean ridge systems where new oceanic crust is being formed, sediments are thinner, as they have had less time to accumulate on the younger crust. As you move away from the ridge spreading center the sediments get progressively thicker (see section 4.

They are giving us the parent's phenotype and genotype:

P1: Yellow, heterozygous

P2: Red, recessive homozygous

Let's assign the letter Y to the yellow allele and y to the red allele.

P1: Yy

P2:yy

Then the Punnett's square would be as follows:

This means 50% of the offspring would be heterozygous yellow birds, and the other 50% would be recessive homozygous red birds.

So, if there are 4 fledglings, 2 would be red and the other 2 would be yellow.

The correct option is B. The temperature increases in the stratosphere because ozone absorbs ultraviolet radiation, and in the thermosphere because of direct exposure to the sun. As altitude increases more ozone is formed and more solar radiation heats molecules, which results in increased temperature in both the stratosphere and the termosphere.

Symbiosis is a kind of ecological relationship where two or more species are closely related in terms of their living habits; they reciprocally benefit from these interactions, for example, they provide each part of the symbiosis with nutrients.

There are too many symbiotic relationships in nature, one of them we can find in organisms such as anemones, and clownfishes; in whale sharks and other fish species that tend to seal the oceans with them, and in pollination, being plants and insects, as we can see in the following pictures:

Considering this, we can say that the correct answer to the question is the third one: C. Two (or more) organisms belonging to different species live closely together and have specific interactions.

Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth's own rotation. Winds range from light breezes to natural hazards such as hurricanes and tornadoes.

To construct linkage maps, scientists estimate the distance between genes on the same chromosome based on the crossover frequency, as indicated by the percentage of recombinant offspring.

On the same chromosome are linked genes. X-linked genes are found on the X chromosome, while genes that are sex-linked are found on a sex chromosome. Linkage maps that depict the positions of genes on chromosomes are created using the frequency of gene crossing-over.

The frequency of crossing-over between two genes on the same chromosome can be used to evaluate linkage. Non-homologous chromosomes do not share any genes. They autonomously assort during meiosis, which gives them a 50% chance of ending up in various gametes. Genes are assumed to be on the same (homologous) chromosome if they appear in different gametes less than 50% of the time, they tend to be inherited together.

It's needed to consider that we have two kinds of cells: somatic cells (which have 2 chromosomes inherited from our parents; 2n), and sexual cells (which have only one chromosome, inherited only from one of our parents; n). This is crucial to understand that somatic cells, whose genetic information we do not inherit, and sexual cells, whose genetic information we do inherit, differ in how they divide themselves. The first one, although they divide themselves, they can't pass a mutation to the offspring, while sexual cells can do, or the B option, which states "cells that are produced when the mutant cell divides".

Explanation:

Clones have the same DNA and the same genes in their nucleus. Therefore, clones have the exact genetic material in their nucleus.

Answer:

The correct answer is D.

The stimulus or physiological variables is the item to be regulated, the maintenance of the feedback loops for the body regulation is called homeostasis (internal activity balance) that is a process that controls the stimulus to each function and how they triggers the response from the body activity. Receptors detects the changes in stimulus and Integrators compare the variable in relation to a set point to singnal the effectors to generate a physiological response.

Somo of the most showed examples of the homeostasis and the feedback loops are:

-Control of body temperature;

-Control of blood glucose.

Resume:

-The name of the process that controls the balance of the physiological variables of the body is: Homeostasis;

-The responsible to start a feedback loop is: the Stimulus (positive or negative);

-The stages for a feedback are: Stimulus ---> Receptors ----> Integrators -----> effectors;

Therefore, for this process the variable that changes in a feedback loop is the stimulus.

The Decomposers which decompose the organic matter from dead plants and animals occupy the last trophic level or the top of the ecological pyramid, the most common examples of decomposers are microorganisms like bacteria, and fungi.

For example, plants that can make their food through the process of photosynthesis are called producers, consumers are of three types herbivores carnivores, omnivores based on their consumption, and decomposers are classified by the type of organic matter they break down.

Scavengers, Detritivores, Saprotrophs.

In the first question: The outside of this organelle is surrounded by a double layer of thylakoids, which are modifications of the chloroplast's membrane.

In the second: The thick fluid inside this organelle is where many of the reactions of photosynthesis take place. This fluid is called the Stroma, which connects all the organs and serves as a buffer for the products and reactants in use.

In the third: One of the single pancake-like discs in this organelle is called a membrane granum.

In the fourth: The entire organelle shown in the image is called a chloroplast.

In the fifth: One of the 'stacks of pancakes" is called a which is the light-harvesting antennae.

In the sixth: The reason this organello is green is because of the pigment absorbing molecule of this organelle, the pigment is chlorophyll-a (at least in plants, and several unicellular photosynthetic organisms, but it is not the only one).

In the sevent: The gases needed as inputs for photosynthesis enter the plant through small pores called stomata.
