During which process do alleles undergo segregation?a. DNA replication.
b. Mitosis.
c. Meiosis.
d. Transcription.

Answers

Alleles undergo segregation ispresent in the mitosis. The answer is B. The first stage is prophase. Thenucleolus disappears and the two centrosomes begin to form the mitotic spindle.The spindle xtends between two opposite poles f the cell. Next is the metaphase.The centromeres of the chromatid pairs align at the center of the mioticspindle. Then anaphase, the centromeres will split that separates the chromatidpair. In here, alleles are formed. They are now called chromosomes. The lastphase is the telophase. The chromosomes will then form a thread-like chromatinand for ache envelope, a nucleoli appears.

The Robinson projection map is considered very useful because _____.all of the continents are the same size
it shows land masses in three dimensions
most distances, sizes, and shapes are accurate
features near edges are most accurate

Answers

The Robinson projection map is considered very useful because most distances, sizes, and shapes are accurate.

Answer:

The correct answer is "most distances, sizes, and shapes are accurate".

Explanation:

The Robinson projection map is an approach to show the entire world in a two dimensional image. Arthur H. Robinson created this projection in 1963 and substituted the the Van der Grinten projection in 1988. The Robinson projection map is considered very useful because most distances, sizes, and shapes are accurate. Therefore, this projection is used for geological purposes in a better way than previous projections.

What secies reproduce rapidly in a new habitat due to lack of parasites and predators that would control the population

Answers

Hi there!

Most native species that evolved with their habitat also have an array of natural predators and parasites to keep the population in check. The exception to this is invasive species. Such species are usually introduced into a habitat artificially and lack the natural predators and parasites present in their original home. 

Therefore, the type of species that normally reproduces quickly with little to no predators to control the population are invasive species.
