It is true that enzymes and proteins are precursors for cell division and are synthesized at the G2 phase of the cell cycle.
G2 PhaseThe G2 phase is the phase that is penultimate to actual cell division in the cell cycle. It is the phase that comes after the S phase during which the cell's DNA is replicated.
At the G2 phase, the cell synthesizes all the necessary proteins and enzymes required for active division. Thereafter, the cell proceeds to the mitotic phase.

Black-and-white warblers migrate from their breeding range in canada to southern florida for the winter. Which is most likely to occur if environmental factors limit the number of female warblers that return to canada?.
If few female warblers return to Canada, there will be few young warbler will hatch.
Seaonal Migration of birdsMigration is the seasonal movement of animals from one location to another.
Since the breeding ground of the Black-and-white warblers is in Canada, a consequence if They fail to return is that their will be reduced number of mating. Hence, few hatched warblers will result.
Therefore, there will be few young warbler that will hatch.

Answer:
C
Explanation:
Genetic drift is when the frequency of a gene variant in a population of species changes due to a change in the environment. Let's use a variety of colored marbles as an example. I have a jar of colored marbles: red, blue, green, and pink. My little brother accidentally shook the jar and lost all the red and blue marbles. Thus, I have only green and pink marbles left.
With genetic mutation, some organisms get damaged/die from the change in the environment, while some don't get too negatively affected.
Thus, the answer C is correct because a change in the environment affected the probability of getting a certain tongue length.

[tex]\huge{\underline{\underline{\boxed{\sf{ \orange{ αηѕωєя : }}}}}}[/tex]
Genetic drift can cause big losses of genetic variation for small populations.Population bottlenecks occur when a population’s size is reduced for at least one generation.Because genetic drift acts more quickly to reduce genetic variation in small populations, undergoing a bottleneck can reduce a population’s genetic variation by a lot, even if the bottleneck doesn’t last for very many generations. This is illustrated by the bags of marbles shown below, where, in generation 2, an unusually small draw creates a bottleneck.Hope Helps~what is the upper layer of earth's mantle where convection occur's??????

B. Explain how using 3D models of cells can help scientists gain a
better understanding of cell structures and function.
Answer:
it could help them by getting a better eye to eye representation of the cells and how they function
3D models provide a better and clear representation of the biological images and objects. It gives the exact visualization of the cell structures projecting in the body.
Why are 3D models important in biology?3D models can be created for studying the cell structures or organs in the body. Such models represent the image with respect to their length, width and height and hence can be ideal for the display of physiological and anatomical structures.
3D moles are ideally useful in monitoring the status of the cells and looking for visible signs of anomalies. It can also be proved as useful in studying the surgical interventions.
3D models can be ideal in assessing the status of tumour and cell proliferation. It can also project the response of a cell or cell structure with respect to stimulus. Such models can be used in academics to provide better understanding of the body of an organism.
Thus, 3D models can be considered important in research and analysis.

Recent biochemical evidence divides all organisms into three domains: Bacteria, Archaea, and Eukarya. Previously, Bacteria and Archaea were viewed as one group. Which statement best describes why Bacteria and Archaea have been placed into separate domains?.
Bacteria and Archaea have been placed separately because their cells have differential compositions. Bacteria and Archaea are prokaryotes.
Archaea and Bacteria domainsArchaea and Bacteria domains are prokaryotes because their cells do not contain membrane-bound organelles or cell nuclei.
However, there are certain phenotypic, structural, and evolutionary features to distinguish Archaea and Bacteria domains.
For example, the Archaea cell membrane contains isoprene hydrophobic groups and phospholipid linkages (it is not found in bacteria).

What can fossils of teeth tell us about extinct animals?.
Answer:
To understand what extinct animals, such as dinosaurs, ate, we can compare their tooth types to the range of tooth types that we see with modern animals such as these carnivorous and omnivorous animals. ... These kinds of clues tell us that this animal was a meat eating animal. This fossil is the jaw of a Hadrosaur.
Explanation:
Teeth from more recent fossils reveal more because they have more isotopes preserved in them. For example, the nitrogen in the teeth of Neanderthals can reveal whether the protein they ate came from plants or animals.
An animal's teeth is literally shaped by its food. That's according to new research from the Department of Geology at the University of Leicester, published in the Royal Society journal Interface. Research shows that the roughness of tooth surfaces can reveal what an animal has been eating.

What property of the cell membrane allows some molecules to pass easily through.
Answer:
selectively permeable
Cell membranes only allow some molecules through. This characteristic is why cell membranes are selectively permeable. They are not impermeable (not letting anything pass) nor are they freely permeable (letting everything can pass). This quality allows a cell to control what enters and exits it.
Answer:
The cell membrane's main trait is its selective permeability, which means that it allows some substances to cross it easily, but not others

Two sister chromatids are held together by the centromere
The ChromosomeThe chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

Compare each patient's cdna sequence to the wild-type cdna sequence. Each patient has one nucleotide-pair substitution mutation. At which nucleotide location is the mutation found for each patient?.
The mutation is a change in the nucleotidic sequence. In the exposed example, Patient 1: nucleotide 143, TTC⇒TGC. Patient 2: nucleotide 143, TTC⇒TCC. Patient 3: nucleotide 147, TTC ⇒ TTG.
What is a mutation?
A mutation is a change or alteration in DNI sequences that introduce new variants.
Many of these are eliminated, but some of them might succeed and be incorporated into each individual.
These mutations are the ones that have been selected by natural selection.
Solving the problemWe know that each sequence initiates with nucleotide number 103 and ends in nucleotide 162.
So first, we will number the nucleotides, from 103 to 162. Each nucleotide has a number in increasing order.
Now, we will identify the mutations in each of the strands by comparing them with the wild-type sequence. The mutation occurs in one of the nucleotides, so we must look for the change in the bases.
Finally, we will identify the nucleotide location of each mutation.
nucleotide wild-type mutated
