the chromatin condenses
into visible chromosomes
Answers
Answer: DNA and proteins contained in the nucleus, known as chromatin, condenses. ... The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell. ... The spindle starts to form during prophase of mitosis

Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

Sedimentary rocks form from rock and mineral fragments, and metamorphic rocks form from existing rock.
True
Or False
Answers
Answer:
True
Explanation:
Sedimentary - A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals.
Metamorphic - These rocks form as existing rocks are subjected to intense heat and/or pressure, usually over long periods of time.

What do humans need to keep mice healthy as pets?
B.
Was there a change in the genetic traits of the mice?
C.
Were the genes of the mice inherited from their parents?
D.
Was there a change in the environment where the mice live?
Answers
Answer:
D if there is a change in environment that would favor black fur you could assume that natural selection caused the fur to change
Explanation:
The question which should be asked to determine whether the population changes are a result of natural selection or artificial selection is that was there a change in the environment where the mice live? Thus, the correct option is D.
What is Natural selection?
Natural selection is the process through which the populations of different living organisms adapt and change with respect to their surrounding environment. Individuals in a population are naturally variable, it means that they are all different in some way or the other. This variation in the population means that some individuals have traits which are better suited to the surrounding environment than others.
If a mouse population changes its color from white to black over many generations, then the question which should be asked is "Was there a change in the environment where the mice live?"
Therefore, the correct option is D.

One of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C. In prokaryotes, which are single-celled organisms that lack a nucleus, evolution occurs primarily through mutations that occur during binary fission.
What is mutation?Prokaryotes, which include bacteria and archaea, are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are known for their remarkable adaptability and ability to evolve rapidly in response to changing environmental conditions, and beneficial mutations that improve an organism's fitness, such as antibiotic resistance, can quickly spread through a population through natural selection.
Hence, one of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C.
