Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 protein stoichiometry ratio of purine and pyrimidine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
What does a DNA repair mutation cause in the Cell cycle?
Answer:
Mutation rates increase substantially in cells defective in DNA mismatch repair or in homologous recombinational repair (HRR). Chromosomal rearrangements and aneuploidy also increase in HRR defective cells. Higher levels of DNA damage not only cause increased mutation, but also cause increased epimutation.

The hormones of the adrenal medulla are modified
(a) fatty acids. (b) amino acids. (c) monosaccharides. (d) nucleotides. (e) steroids.
Answer:
b
Explanation:
hormones of adrenal medulla are Adrenaline and non- Adrenaline. they are the derivatives of amino acids called Tyrosine( aromatic Amino acid)
The hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.
What is the Adrenal medulla?The adrenal medulla may be defined as an internal part or region of the adrenal gland which is located at the region of the top of each kidney.
The adrenal gland is a small gland that comprises the adrenal cortex and adrenal medulla. The adrenal cortex synthesizes steroids hormones like mineralocorticoids, glucocorticoids, etc. While the adrenal medulla is responsible for the secretion of epinephrine and norepinephrine.
The hormone epinephrine is also known as adrenaline. It is often called catecholamine. This epinephrine is extracted from the derivatives of amino acids known as tyrosine.
Therefore, the hormones of the adrenal medulla are modified versions of amino acids. Thus, the correct option is B.

Solids have a definite:
a Shape
b Volume
c Arrangement of atoms, molecules
d All of the above
Answer:
d all of the above :)
Explanation:
hope this helped
Answer:
D) All of the above.
Explanation:
The Shape of a solid does not change (with exceptions), and the atoms typically remain static with little freedom of movement.
The volume of the solid also stays exactly the same if no external adjustments are made.
The arrangements of atoms & molecules are definitive and packed together, giving little movement, therefore allowing the solid to keep form.

Why is it important to center the object you want to look at in your field of view before changing to a higher magnification objective lens? A. So the object is still in your field of view at the higher magnification. B. So you can always see the entire object at the higher magnification. C. So you do not damage the higher magnification objective lens.
Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
The first unstable compound formed during C3 cycle is:
(a) 3-carboxy,2-keto, 1,6 bi phosphorobitol
(c) 2-carboxy,3-keto,1,5 biphosphorobitol
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
(d) 3-carboxy,3-keto, 1,6-biphosphorobitol
Answer:
(b) 2-carboxy,3-keto,1,5-biphosphorobitol
Explanation:
2-carboxy, 3-keto, 1,5-biphosphorobitol is the first unstable molecule formed during the C3 cycle. Due to its instability, this molecule is quickly broken down into two molecules each containing 3 carbon atoms, called 3-phosphoglyceric acid, this breakdown is done through water in a process known as hydrolysis.
what are the chances that a color blind man will have a color blind grandson what are the genotypes for all involved.
Answer:
Depends
Explanation:
It depends if the genotypes are hetero.zygous or resessive/dominant homo.zygous. Being colorblind could be represented by a resessive genotype like, bb. if their son/daughter has Bb or bb or their son/daughter in law has a resessive trait then having a color blind grandchild maybe possible. The colorblind grandson has parents that both have at least 1 resessive trait, then the grandson could not be colorblind.

What is the difference between global effects and local effects.
Answer:
golbal means around the world but local means next to you
Answer:
A global effect generally affects, as the term implies, the world as a whole, or at least a major part of the world, while a local effect would be just in a distinctive area.
For example, if the world is heating up due to CO2 emissions, it heats up in an global effect, resulting in the median temperature rising in all areas of the world. However, the world heating up may only mean a drought in distinctive areas that are typically already leaning towards the drier side (local effect), while the others receive a greater than usual volume of water due to rising temperatures.

Why don’t mosses grow very tall?
They need energy to make food, which they get by being close to the ground.
They don’t have roots, so they must be near water.
They need to send out spores via water.
They have seeds that need to roll away.
Answer:
Hello~
Llamalover here!
Mosses have some water-conducting cells, but they do not have the empty, lignin-reinforced cells that allow vascular plants to transport water with strong pressure gradients. Thus, mosses have very limited water transport ability and can't grow very tall.
So, your answer is They need to send out spores via water. I believe
