Describe what happens during the phases of mitosis
Answer:
Mitosis is the phase where the cell splits its chromosomes equally among two daughter cells, and branches off into more cells.
In mitosis, there is the prophase, prometaphase, metaphase, anaphase, and telophase.
The prophase is where the nuclear envelope breaks down and chromosomes attach to spindle fibers. The metaphase is where chromosomes line up at the equator. In the anaphase, the cells move to opposite poles to split. Last but not least, the telophase. In this final phase, the two nuclei split into new cells.
What 2 plants in Yellowstone national park declined as a result of the elk population boom?
how do mutations contribute to genetic variation
Answer: Genetic Change
Explanation:
Mutations contribute to genetic variation by causing new traits to emerge. Mutations happen when there is a change in the DNA of a creature developing in utero. These random changes in creatures are common, although most mutations end up being lethal or inhibiting to the organism. In rare cases, this mutation can prove benificial or helpful, and if the organism reproduces and the trait is passed along, it could become a new branch of genetic variation within the species.

Transformation is the transfer of dna from a donor to a recipient cell:
Transformation is the transfer of DNA from a donor to a recipient cell, mediated by a bacteriophage through the process of crossing over.
What do you mean by DNA?DNA stands for Deoxyriobo nucleic acid. It is considered the genetic material in most of the organisms living on the earth's surface.
It is the process that involves the horizontal gene transfer among prokaryotes. During this process, the DNA of the donor cell integrates into the recipient cell.
Therefore, transformation is the transfer of DNA from a donor to a recipient cell, mediated by a bacteriophage through the process of crossing over.

Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.
What do you mean by Natural selection?Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.
Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.

Food webs and the ecosystems that support them look different in different parts of the world depending on their habitat conditions.
What do you mean by Ecosystem?An Ecosystem may be defined as a place or area where members of different species or communities live and interact with one other for the purpose of food, shelter, space, or other resources.
Food webs constantly supply energy from one level of organisms to other levels of organisms randomly. It basically depends on the type of habitation present in particular conditions.
The place of producers remains the same for food webs and food chains. The food chain transferred energy in a defined way, rather than food webs.
Therefore, food webs and the ecosystems that support them look different in different parts of the world depending on their habitat conditions.

A mountain range that separates two
species of bears is an example of which
of the following types of barriers?
A. ecologic isolation
B. temporal isolation
C. geographic isolation
D. mechanical isolation
A mountain range that separates two species of bears is an example of geographic isolation. Thus, the correct option for this question is C.
What is Species separation?Species separation may be characterized as a type of mechanism through which species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
The process of speciation may occur due to isolating mechanisms, like geographical isolation which is known as allopatric isolation. Different geographical areas play an important role in the process of separating two or more species that give rise to speciation.
Therefore, a mountain range that separates two species of bears is an example of geographic isolation. Thus, the correct option for this question is C.
