Explain the steps in the formation of sedimentary rock.

Fragmentation and regeneration are forms of asexual reproduction.

There are no sexual cells involved, and they divide by mitosis, giving genetically identical individuals.

We have to consider that sexual and asexual reproduction differs in that the first one requires both organisms, one male and one female, to produce genetically different offspring, while the second one requires only one organism to produce genetically identical offspring.

About the kind of organisms mentioned in the answer options, we can say Protista includes Fungi, so the answer options that include both of them can be excluded, mainly due to choosing one of those options would exclude other organisms that can be in fact sexual or asexual.

Having this clear, we can say that organisms such as those belonging to the Plantae, Fungi, and Animalia kingdoms can reproduce in these two ways (unlike Archaea, and Eubacteria).

In the pictures below we can see examples of organisms of these species that can reproduce both asexually and sexually. In them, we can see ants (which can produce eggs with only the genetic load of one parental organism), plants (which can reproduce through branches, but also through seeds), and fungi (which can reproduce also mitotically and meiotically), as in the second answer option.

The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.

Answer: Punnet Square

If a base sequence of a strand of DNA is changed from A-T-G to A-T-C, the mRNA will be changed from U-A-C to U-A-G.

If the parents have XXrgrg and XYrg genotype, they have a 50% chance of producing an individual XX with red-colour deficiency.

Therefore, their offspring has 0% chance of being XY with normal colour vision.

Though DNA is responsible for the instructions for the assembly process, it is RNA that synthesizes (assemles) the proteins.

The correct answer is TRUE,

The first types of cells that appeared on Earth were the most simple cells that we know, these are prokaryotic cells. Eukaryotic cells have most likely evolved from prokaryotic cells later. Viruses are not cell types, so they can not considered a posible answer to this question.

Answer: b.

The telencephalon is formed by four major structures: cerebral cortex (the hemispheres parts of the brain), limbic forebrain (brain part where you can find amigdala), basal ganglia, and the olfactory system. There are also the subcortical structures that includes the hippocampus (part og hippocampal formation in the brain), and amygdala (brain center to regulate memory and others associated functions). The telencephalon is the farthest end of the neural tube, being during the developtment of the organism divided into two structures that will form the cerebral hemispheres. The cerebral cortex is also divided into prefrontal cortex, motor cortex, occipital cortex, and so on.

Cells divide for three reasosn: growth, reproduction and repair.

Onion root tips and whitefish embryos presents cells that's always undergoing mitosis.

Onion root tips are always growing to get more water and nutrients from the soil, therefore mitosis is always occuring to duplicate the cells and maintain a growing rate.

Whitefish embryos have cells that are undergoing mitosis rapidly, as it is a phase of intense growing and formation of the embryos to become fish.

The endosymbiotic theory states that some organelles in eukaryotic cells are original from prokaryotic microbes (bacteria), being mitochondria and chloroplast the example of the theory. Therefore, for the students demonstrate the endosymbiotic theory with the biological material that was offered to them they have to show the big bacteria ingesting the small one.

Mammals that feed on ants and termites have similar characteristics because they allow for a greater rate of success in getting this kind of food.

Even when they are not closely related, they share these characteristics because they share the same ecological conditions.

This is an example of convergent evolution, where similar characteristics evolve in distantly related organisms. (C is the right answer)

Answer:

I'm pretty sure the answer is c, since if they don't adapt they will die off.

It wouldn't be respiration, because it has no direct relation to procreation. It wouldn't be independent assortment also, because this is the phenomenon that would explain the expected result. It also wouldn't be cytokinesis because this phenomenon is related to cell division, in which the combinations are already set. So, it is crossing-over, because this phenomenon occurs when ther is a switch between homologous chromatids occured during meiosis, which means that the chromosomes are so close to each other that they can trade parts of itselfs with other chromosomes, unexpectedly providing a different outcome than the one that was expected. So, the answer is crossing-over.

The cell membrane structure is very important because everything alive has cell membranes. The model used to describe the cell membrane is called the fluid mosaic model.

Fluid Mosaic Model has been known as the fluid mosaic model, which has been proposed by S.J. Singer and Garth L. Nicolson in 1972,explains the structure and composition of the cell membrane.

The plasma membrane has the combination of phospoholipids, cholesterol, proteins and carbohydrates.The model shows that the plasma membrane has a lipid bilayer made of phospholipids.

Burning fossil fuels such as gasoline or oil generates numerous pollutants, such as ashes, sulfur and carbon dioxides, which contaminate the environment, affect air quality and contribute to global warming.

One of the compounds not generated during this process is copper sulfates. Therefore, the answer is A.

Explanation:

Step 1: Initiation

Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases.

Step 2: Elongation

Elongation is the addition of nucleotides to the mRNA strand. RNA polymerase reads the unwound DNA strand and builds the mRNA molecule, using complementary base pairs. During this process, an adenine (A) in the DNA binds to an uracil (U) in the RNA.

Step 3: Termination

Termination is the ending of transcription, and occurs when RNA polymerase crosses a stop (termination) sequence in the gene. The mRNA strand is complete, and it detaches from DNA.

Water is needed for all life forms, including microorganisms, removing the water from food to preserve it means the microorganisms cannot perform the chemical reactions needed to consume the food, so the food is preserved for a longer time (option B is the right answer).

Topic: Population growth

Introduction:

The Biotic potential is described by the unrestricted growth of populations. This event causes the maximum growth of that population.

By definition, when a population reaches the biotic potential, then the species has its highest birthrate or a high number of births or accelerated population growth and lowest mortality rate.

we can conclude that the correct answer is:

D. Biotic Potential

DNA SEQUENCE OF NORMAL CAT: CCC TCC TCT GCT

DNA SEQUENCE OF ALBINO CAT: CCT CCT CTG CTG

To change DNA sequence to mRNA sequence, remember uracil replaces thymine in mRNA. A=U; G=C

mRNA SEQUENCE OF NORMAL CAT: GGG AGG AGA CGA

mRNA SEQUENCE OF ALBINO CAT: GGA GGA GAC GAC

The mutation changed the structure of the genes, which changed the structure of the proteins. This changed the function of the genes, which caused the cat to have albino traits.

Giraffes are believed to have short necks but there was a chance in neck length variations. Some giraffes have a little longer compared to the average length. The main source of nutrition for giraffes is tree leaves. Maybe there was an environmental change that occurred that there was a limited source of leaves and as a result, there were more giraffes than trees; therefore, there is a struggle for existence.

In this event, variation, fitness differences, and inheritance (3 ingredients of natural selection) must occur for the species to survive. Longer necked giraffes are more likely to reach the leaves of the trees and have a higher chance of survival and reproduction; thus, they have greater fitness. This trait (long necks) was passed on to the offspring and eventually, all giraffes have long necks.

The allele frequency of the population of giraffes eventually changes to favor the trait that will give the species a higher chance of survival in their environment.

The mass of the box is 2 kg.

According to Newton's second law, the force acting on a body is the product of its mass of the body and acceleration produced due to the force. i.e.,

[tex]F=ma[/tex],

where,  [tex]F[/tex] is the force acting on the body, [tex]m[/tex] is the mass of the body and [tex]a[/tex] is the acceleration.

Now, as per the question:

Force, [tex]F=10 N[/tex]

Acceleration, [tex]a=5m/s^{2}[/tex]

Thus, the mass of box ,

[tex]m=\frac{F}{a}[/tex]

[tex]m=\frac{10}{5}[/tex]

    [tex]= 2 kg[/tex]

Therefore, the mass of box is [tex]2 kg.[/tex]

EXPLANATION/ANSWER:

The term "plankton" comes from the Greek word "planktos" which means wandering. Planktons are microscopic organisms that are floating and being carried by tides and currents. There are two types of planktons: phytoplankton and zooplankton. Phytoplanktons are aquatic microorganisms that have chlorophyll and can make food from sunlight. Zooplanktons are aquatic microorganisms that consume phytoplanktons or other zooplanktons.

Answer

B. when there is no evolution

Explanation

Incomplete dominance is a type of interaction in which both genes are expressed but in a mixed form, frequently creating a third phenotype. For example, when having a flower with a gene for red petals and another gene for white petals, the petals could be pink. When talking about the blood type system, there's no third phenotype expressed. Sometimes you'll find a combination of the two different types present in the genes, but never a third one. Therefore, A and B are incorrect, because they include incomplete dominance.

Codominance occurs when the two types that are present in the genes are expressed equally. This is the case when we talk about the A&B blood types. When a person has both A and B genotype for the blood type system, both of them will be expressed, and the blood type will be AB. So none of them will be dominant over the other. So, C is incorrect, as it states that between A&B you'll find a complete dominance relationship, but it is a codominance interaction.

At last, a complete dominance occurs when one of the genes is expressed above the other. This happens when you have one gene for A OR B type, and one gene for O type. In this case, the O gene will be suppressed because it is a recessive gene, and the other one will be expressed (being A or B). Therefore, E is incorrect too because there's not only codominance, there's also complete dominance.

We can say, than, that the correct answer is the one that presents a codominance interaction between A&B and a complete dominance interaction between A&B compared to O.

Therefore, the correct answer is D. Codominance (A&B) and complete dominance (A&B compared to O)
