Fantom [35]2 years ago

Answer:

1.  first part Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins or other molecules, it is called gene expression.  second part Double-stranded DNA consists of two polynucleotides that are arranged such that the nitrogenous bases within one polynucleotide are attached to the nitrogenous bases within another polynucleotide by way of special chemical bonds called hydrogen bonds.

2. Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.

3. Non-coding DNA sequences do not code for amino acids. Most non-coding DNA lies between genes on the chromosome and has no known function. Other non-coding DNA, called introns, is found within genes. Some non-coding DNA plays a role in the regulation of gene expression.

When there is not enough carbon dioxide in a plant, a process called photorespiration may occur. This process uses the excess ox
sergiy2304 [10]

A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.

<h3>What is the difference between photorespiration and respiration?</h3>

One of the basic differences between photorespiration and respiration concerns the effect of O2 on the two processes. Respiration saturates when O2 reaches approximately 2%, while photorespiration does not reach saturation in a pure O2 atmosphere.

<h3>Under what conditions does photorespiration occur?</h3>

Photorespiration is an expensive metabolic pathway that occurs when the Calvin Cycle enzyme rubisco acts on oxygen instead of carbon dioxide.

With this information, we can conclude that A prolonged period of photorespiration would affect a plant, giving a significant evolutionary advantage to plant species in dry climates.

Echinoderms _____. _____ Select one: a. have an exoskeleton of hard calcareous plates b. often use tube feet to move around in t
atroni [7]

Answer:

B. often use tube feet to move around in their environment

Explanation:

Tube feet are tiny tubular projections of echinoderms on the underside (oral side). They are a member of the echinoderm water vascular system.

Tubular feet are used for feeding, breathing and shifting. They are arranged around the sides, in grooves. They work by hydraulic pressure. They are used to transfer food in the centre to the oral mouth, and may stick to surfaces. Tube feet allow certain animals to stick and travel slowly to the ocean floor. for example starfish uses tube feet for the above functions.

Hence, the correct option is B.
