<h3>Answer;</h3>

D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.

<h3>Explanation;</h3>

Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism. Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation. Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.

Joyce is planting tulips in her garden, and she has 5 red bulbs and 5 white bulbs to plant in one row. What is the probability t

Stolb23 [73]

Answer:

$\frac{1}{126}$ or 0.0079.

Explanation:

Joyce is planting tulips in her garden.

Number of red (R) bulbs = 5

Number of white (W) bulbs = 5

Total number of ways to plant 10 bulbs in one row is

$\text{Total ways}=\frac{10!}{5!5!}$

$\text{Total ways}=\frac{10\times 9\times 8\times 7\times 6\times 5!}{5\times 4\times 3\times 2\times 1\times 5!}$

Cancel out common factors.

$\text{Total ways}=252$

It is given that she randomly plants the bulbs so that all 5 red bulbs are next to each other and all 5 white bulbs are next to each other.

Required outcomes are

RRRRRWWWWW and WWWWWRRRRR

$\text{Required outcomes}=2$

Formula for probability:

$Probability=\frac{\text{Required outcomes}}{\text{Total ways}}$

$Probability=\frac{2}{252}$

$Probability=\frac{1}{126}$

$Probability\approx 0.0079$

Therefore the required probability is $\frac{1}{126}$ or 0.0079.

Compare and contrast what happens in mitosis and meiosis and discuss the importance of each process to a living organism.

avanturin [10]

Lets see both procedures:
Mitosis is a process of cell duplication during which one cell gives rise to two genetically identical daughter cells. Meiosis, on the other hand, is a division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell. Mitosis is used by single celled organisms to reproduce; it is also used for the organic growth of tissues, fibers, and mibranes. Meiosis is useful for sexual reproduction of organisms. I hope this can help greatly
