ill give brain thing to first answer

Speciation, which leads to diversity among species through natural
selection, occurs when
Once similar species are no longer able to mate and produce fertile
offspring
Organisms develop characteristics that mimic traits of a completely
different species.
Species experience change within their lineage and develop new
characteristics.
Species interact with other species in an ecosystem and develop
similar traits to each other.

Answers

Answer 1

Answer:

Natural selection and speciation: 'Ecological speciation'. ... Natural selection is generally recognized as a central mechanism of evolutionary change within species. Thus, natural selection plays a major role in generating the array of phenotypic and genetic diversity observed in nature.

Which two phases do the chromosomes exist as chromatin (unraveled form of chromosomes)?

Answers

Answer:

During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).

Explanation:

Answer:

Prophase is the first step of mitosis. This is when the genetic fibers within the cell’s nucleus, known as chromatin, begin to condense and become tightly compacted together. During interphase, the parent cell’s chromosomes are replicated, but they aren’t yet visible.

Explanation:

Your friend makes a claim that the image to the right shows facilitated
diffusion. You are an educated Honors Biology student, and you believe
that he/she is incorrect in their claim. Make a claim as to which type of
cellular transport is represented in the image (1 point)State TWO pieces of
evidence from the image that supports your claim (2 points).*

Answers

Answer:

Facilitated diffusion is a type of passive transport of molecules down the concentration gradient between two sides of a membrane which doesn't require ATP and instead uses a specific transmembrane protein.

Active transport requires instead ATP and it is the process drawn in the figure. Moreover the figure illustrates that molecules are moving against their concentration gradient.

This dichotomous key helps scientists classify within the arthropoda phylum. If scientists discover an organism with: less than 10 legs, 6 legs, wings, wings with 1 or 2 colors, with legs that are approximately the same length, wings that are not net-like, and wings that meet in a straight line down the back, how would this organism be classified?

Answers

You'll have to follow the dichotomous key that's provided to you. Start by choosing less than 10 legs, then choose 6 legs, then with wings, then wings with 1 or 2 colors... etc. You should end up identifying an organism this way.. following the path.

MITOSIS. Tell what happens to the cell at each part of the cell cycle starting at
Interphase, then the stages of Mitosis (PMAT) and ending at Cytokinesis. (This should be
a longer response than one sentence!!)

Answers

Answer:

The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.

Explanation:

During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
