Aneli [31]

Answer: a. Genetic recombination (crossing over)

b. Can also be explained in terms of crossing over

c. Non disjunction of homologous chromosomes in meiosis 1

Explanation:

The process that allows for the transfer of both the paternal and maternal materials to is the crossing over process that takes at meiosis 1 changing them to secondary spermatocytes. While they are still primary spermatocytes, they are still diploid cells having both the maternal and paternal chromosomes. But since the spermatozoon is an haploid cell, it is able to retail some of both parents chromosome by the crossing over event which takes place between homologous paternal and maternal chromosomes allowing them to exchange materials. Thus the chromosomal contents of the primary spermatocyte differs from that of the spermatozoon.

C. This can occur as a result of the one of the homologous chromosome pair refusing to separate at meiosis 1 with one gamete containing 4 chromosomes/8 sister chromatids and the second having 2 chromosomes/4 sister chromatids.

enzymes degrade proteins, lipids, and large carbohydrates to smaller building blocks in the digestive tract. why must these macr
Rom4ik [11]

Amino acids, which serve as the "building blocks" of proteins, are disassembled. These tiny molecules can be absorbed through the stomach wall after being released.

<h3>Describe how the macronutrients in your diet are digested and then put back together to form the cell structure.</h3>

The principal macromolecules, from which all life is derived, are macrounits in our diet. The smaller subunits of these macromolecules must be broken down in order to be released. The circulatory system carries the digestively released components to the body's cells. These subunits serve as the building blocks for the macromolecules required for cellular structure and function, which are then put together by cells.

Proteins, lipids, and carbohydrates are examples of macromolecules.

The fact that all three macromolecules are hydrocarbons means that the majority of their atoms are made up of hydrogen and carbon.

Nitrogen atoms are found in proteins and in lipids.

Carbon atoms make up carbohydrates.

Simple carbohydrates are formed when complex carbohydrates are hydrated (by adding hydrogen and oxygen ions).

Dehydration of simple carbohydrates causes them to bind together in chains to create complex carbs. This can be reversed.

The image below shows a close-up of the crystals formed in a pegmatitic rock. Which characteristic provides the best evidence th
VLD [36.1K]

Answer:

Option C (very coarse texture) is the appropriate one.

Explanation:

  • Everything always cools quickly because once magma reinforces above that of the ocean floor and perhaps the shape it possesses seems to be agricultural context, color temperature, and so on. But as magma settles down underneath the layer, it gets sufficiently opportunity to solidify, culminating in a much more gritty texture as well as color change, respectively.
  • We then assume that perhaps the assumption of whether concrete solidified buried underground correlates to a rather coarse framework.

Other decisions aren't linked to the circumstance issued. So the one above is indeed the best one.
