Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.
Kruka [31]

Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.

How does mutation relate to variation
Anastasy [175]

Answer:

Mutation is the source for new genetic variation: Genetic variation is brought about by random mutation. Without mutation, genetic variation cannot occur. Mutation is a change in the genetic code in DNA and can lead to a change in the protein that is coded for that segment of DNA.

Explanation:

Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

If two individuals have a certain phenotype, does that mean they must have the same genotype?
eduard

Answer:

No.As we know that phenotype depends on physical appearance whereas genotype is genetical materials. So person having same phenotype doesn't mean they have same genotype.

If these hydrocarbons were similar in size, which one would most likely be an alkyne?
OleMash [197]
The hydrocarbon which would most likely be an alkyne is COMPOUND W WHICH HAS A BOILING POINT OF -23.
This is because, among hydrocarbons, alkynes have the highest boiling points as a result of the triple bonds in their structures.
The boiling points of the other compounds are -103.7, -47 and -75; all these boiling points are lower than that of compound W.
