FinnZ [79.3K]

Answer:

It can change mouthparts, the antennae, wings, or claws.

Explanation:

The beetle is an insect that is feed by plants, of course it will prefer some plants over another, but depending the plants that surround it can change some of its body parts.

The mouth parts can change because if the leaves are thinner or thicker the mouth as the claws can get smaller or larger depending the needs.

Also if the plants are colorful or they have strong aromas, the antennae can grow or get smaller to reach the plants.

The distance among the plants, also can influence in the size of the wings, because maybe this beetle need to fly long distances between one plant and another.

Identify the following by typing (a) for mitosis or (b) for meiosis on the line before the statements: _____ produces 4 unique g
kenny6666 [7]

Answer:

b - produces 4 unique gametes

a - begins with a somatic cell

a - produces only 2 identical cells

a - has only one nuclear division

b - happens in the testes and ovaries

b - daughter cells are haploid

b - has two nuclear divisions

a - daughter cells are diploid

Explanation:

Mitosis is a kind of cell division that involves the formation of two daughter cells, which are genetically identical and have the same number of chromosomes as their parent cell (diploid). Mitosis occurs in body or somatic cells for repair and multiplication. Mitosis involves only one nuclear division.

Meiosis, on the contrary, involves formation of four daughter cells that are genetically different from the parent cell and have a reduced chromosomal number (by half). Meiosis occurs in reproductive cells like tested or ovaries. Meiosis occurs in two nuclear divisions.

2. Tim and Stephanie are devastated when the
saul85 [17]

Answer:

Explanation:

<em>Tim and Stephanie are devastated when they find out their newborn son has hemophilia- sex-linked recessive disease. Tim is shocked because he doesn’t have hemophilia, and figured if his son has it he would have gotten it from him. Is Tim correct in his thinking? Explain. Also explain what their genotypes must be in order for neither parents to have the disease but their son does. Create a Punnett square, and indicate the mother's and father's genotype.</em>

<em />

First of all, the thinking of Tim is wrong. Hemophilia is X-linked and a male (XY) child always inherits his X chromosome from his mother. Hence, <u>the newborn son of Tim must have inherited the allele for the disease from Stephanie.</u>

Now, neither Tim nor Stephanie showed any symptom of hemophilia. It could only mean that Tim is totally free of the hemophilic allele while Stephanie is a carrier for it. Because a man has just one X chromosome, he can either be totally free of the abnormality or affected by it, no in-between. A woman has two X chromosomes, hence, she can be totally free, a carrier, or affected for the disease. Assuming the allele for hemophilia to be h, Tim's genotype would, therefore, be X^HY while that of his wife would be X^HX^h .

The Punnet's square analysis of the cross between Tim and Stephanie is indicated in the attached image.
