Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation. true false User: The nuclear envelope disintegrates during _____.
metaphase
prophase
anaphase
telophase

Answers

Question 1. The statement that 'Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation' is true. Crossing over is the exchange of genetic material between homologous chromosomes that occurs during meiosis. As the result, the daughter cells are genetically different from mother cells. It is one of the ways to produce genetic variation. Question 2. The nuclear envelope disintegrates during prophase. This is the process that occurs at the beginning of mitosis. During prophase, the first phase of mitosis, the chromosomes condense and the nuclear envelope disintegrates. At the end of mitosis, the chromosomes will decondense and the nuclear envelope will re-form.
Prophase is the answer

Comparative _____ suggests organisms that are more closely related have more similar embryo development.

Answers

Comparative anatomy suggests that organisms that are more closely related have more similar embryo development. This is because comparative anatomy is literally the science/study of similarities in the anatomies of organisms. Organisms that are more similar (i.e. have more homologous structures) tend to develop more similarly; otherwise, their structures would be rather different (hence why a plant and a person are not similar and do not develop similarly).

Hope this helps :)

Answer:

Embryology

Explanation:

Comparative Embryology is the field of embryology. It deals with the study and comparision of the development, morphology, anatomy, physiology and genetic make of embryos belonging to different species. It also help in determining the evolutionary relatedness of the embryos of the previously existing species and present day organisms on the basis of the similarities and differences in the embryo features. All embryos pass through the stage of few to multiple celled zygotes. The differentiation of the zygote results in the clump of cells called as morulas then into hollow balls of cells called as blastulas. The differentiation of blastula leads to the creation of organs of the body.

Chemical reactions carried out by living systems depend on the ability of someorganisms to capture and use atoms from nonliving sources in the environment.
The specific subset of these reactions that break down nutrients in food can be
described as _____________.
(a) metabolic.
(b) catabolic.
(c) anabolic.
(d) biosynthetic.

Answers

Answer:

(B) Catabolic.

Explanation:

The metabolism refers to the chemical reactions which are used by the organisms to sustain their life therefore metabolism is considered a characteristic feature of the living organisms.

The metabolism involves either the formation of a molecule from the smaller subunits or monomer through a process known as anabolism and other involves the breakdown of the larger molecule into smaller subunits through catabolism.

In the given question, the breakdown of the food particle which is usually the complex biomolecules is broken down into simpler subunits through a catabolic reaction. The smaller subunits of molecules are easily absorbed ad then utilised by the body.

Thus, Option-B is the correct answer.

This device can be used to remove most biological agents that enter a house.a. High Efficiency Particulate Air (HEPA) filter.
B. Pure Air Filtering System (PAFS).
C. Biological Identification and Screening Filter (BISF).

Answers

The correct answer for the question that is being presented above is this one: "a. High Efficiency Particulate Air (HEPA) filter." This device can be used to remove most biological agents that enter a house. It is called the High Efficiency Particulate Air (HEPA) filter. An air purifier. It sucks all the dust out of the air and gives it a cleaner atmosphere.

In horses, black (B) is the dominant color; brown (b) is the recessive color. Consider the cross seen here, between two black horses (Bb). What is the probability that these two horses will have a foal that is brown?A) 0%
B) 25%
C) 40%
D) 50%

Answers

Answer: The correct answer is 25%.

Black color (B) of horse is a dominant trait over brown (b) color, which is a recessive trait. As we know that dominant gene masks the expression of recessive gene, therefore brown horse color will only be produced in the genpotype bb.

On the other hand, there are two possible genotypes for black horse color that is BB and Bb.

As per the question, parental genotypes are Bb and Bb. When they are crossed, they will produce 25 % foal with brown color (bb).

Refer punnett square.
B) 25% 

that is 100% CORRECT
