The correct answer is B. Selective breeding.


Selective breeding has led to most modern domesticated livestock and crops.


Selective breeding is termed as the process by which human being use plant breeding and animal breeding to selectively develop a certain phenotypic traits.

Animals breeding like outcrossing, linebreeding, and inbreeding are being utilized the same way applies to plant breeding.

Selective breeding can result from process of human cultivation and can produce undesirable results.

Which of the following statements is a correct distinction between autotrophs and heterotrophs?
Anettt [7]

Answer:

Autotrophs, but not heterotrophs, can nourish themselves beginning with and other nutrients that are inorganic.

Explanation:

Unlike heterotrophs, autotrophs such as green plants, are able to synthesize their food (in form of sugar molecules) starting with inorganic molecules like atmospheric carbon dioxide, water in the presence of sunlight.

This is commonly known as photosynthesis. The equation is shown below

6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy

Each orientation of chromosomes produces gametes with the same genetic information from each parent.
oksano4ka [1.4K]

Answer: a) true

Explanation:

The goal of mitosis is to produce daughter cells that are genetically identical to the mother cell, without a single extra or missing chromosome. Meiosis, on the other hand, is only used for one purpose in the human body: the production of gametes or sex cells, i.e. sperm and eggs. The question is oriented to mitosis, <u>in which prior to this cell division, the cell duplicates its DNA</u> so that each daughter cell then inherits the genetic material. That is, the cell originally possesses 23 chromosomes, they duplicate to a total of 46 so that then each daughter cell receives 23.

The metaphase is the second phase of mitosis and meiosis that occurs after prophase where the envelope is lost and microtubules of the achromatic spindle (also called meiotic or mitotic) appear.

During metaphase, the chromosomes align themselves in the middle of the cell and this balanced midline spindle alignment is due to the equal and opposing forces generated by the kinetochore brothers.

Then during metaphase, the chromosomes will line up in the center of the cell to be separated and go each to a different daughter cell. But the moment they're found there, each orientation of chromosomes produces gametes with the same genetic information from each parent. <u>Because because there have been no changes or mutations in the chromosomes, they have duplicated and have the same genetic information.</u>
