Answers

Answer 1

Answer:

Lymphocytes

Explanation:

A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins. The T cells destroy the body's own cells that have themselves been taken over by viruses or become cancerous.

what hormone directly opposes the actions of natriuretic hormones?

Answers

Aldosterone!
Explanation: Aldosterone reabsorbs sodium in which is associated with osmotic recovery of water is in direct opposition of natriuretic hormones since it allows secretion of water.

The hormone that directly opposes the actions of natriuretic hormones is aldosterone.

Aldosterone is a hormone produced by the adrenal glands, specifically the adrenal cortex. It acts on the kidneys to promote the reabsorption of sodium ions and the excretion of potassium ions.

Natriuretic hormones, on the other hand, promote the excretion of sodium ions and the reabsorption of potassium ions in the kidneys, leading to increased urine production and decreased blood volume.

Therefore, aldosterone counteracts the effects of natriuretic hormones by increasing sodium reabsorption and reducing potassium excretion, which helps to retain water and maintain blood pressure.

In summary, while natriuretic hormones promote sodium excretion and water loss, aldosterone works in the opposite direction by promoting sodium reabsorption and water retention.

the countries with the highest fertility rates are also the ones with the highest infant mortality rates. which one causes which and how do we know?

Answers

Answer: Higher infant mortality rates cause higher fertility rates.

Explanation:

Countries with high infant mortality rates are usually countries where families rely on children to help out the family. High infant mortality rates and a need for children means that those people will continue to try to have children until they have some that survive. If more children die, and people need to have more children, there will be a higher fertility rate.

What is the major consideration in setting the lower limit of cell size?
A. The cell size must be small as to fit all the processes and structures to support life.
B. The cell must be large enough to fight the pathogens.
C. The cell must be large enough to attach to a substrate.
D. The lower limit should be small enough for the cell to move in the fluid efficiently.

Answers

Answer:

c

Explanation:

The lower limit should be small enough for the cell to move in the fluid efficiently. Therefore, option (D) is correct.

The major consideration in setting the lower limit of cell size is the need for the cell to move in fluid efficiently. As cells become smaller, their surface area-to-volume ratio increases, allowing for more effective exchange of nutrients, gases, and waste products across their membrane.

This is particularly important for cells living in fluid environments where diffusion plays a crucial role in these exchanges. Small cells have an advantage in absorbing and expelling substances due to their larger surface area relative to their volume. Therefore, the efficiency of nutrient uptake and waste removal becomes more effective with smaller cell sizes, making efficient movement in fluid environments a significant factor in determining the lower limit of cell size. Thus, option (D) is correct.

Even though human proteins are made from only 20 different amino acids, there are thousands of differen proteins found in human cells. What allows for so much variation in the proteins?​

Answers

Answer:

Amino acids are the basic building blocks of proteins, and they serve as the nitrogenous backbones for compounds like neurotransmitters and hormones. In chemistry, an amino acid is an organic compound that contains both an amino (-NH2) and carboxylic acid (-COOH) functional group, hence the name amino acid. Proteins are long chains or polymers of a specific type of amino acid known as an alpha-amino acid. Alpha-amino acids are unique because the amino and carboxylic acid functional groups are separated by only one carbon atom, which is usually a chiral carbon. In this article, we will solely focus on the alpha-amino acids that make up proteins

If I had a section of DNA that contains 350 nucleotides and the A's and Ts made up 200 of
those nucleotides, how many As
Gs
Cs
and Ts
do I have?(.5 points each response)

Answers

Answer:

100 A

100 T

75   C

75   G

Explanation:

there will be an equal amount of thymine and adenine since they bind together so, 200/2 = 100 each

now there is 150 nucleotides left

guanine binds to cytosine so they also have an equal amount, so 150/2=75

Given, the number of nucleotides in the section of DNA = 350Nucleotides in DNA are of four types - Adenine (A), Guanine (G), Thymine (T), Cytosine (C).Adenine pairs with Thymine while Guanine pairs with Cytosine.Given, there are 200 nucleotides made by Adenine and Thymine.We know, Adenine pairs with Thymine so they will have equal number of nucleotides.So, the number of Adenine = the number of Thymine = 200 ÷ 2 = 100Number of nucleotides made by Guanine and Cytosine = 350 - 200 = 150We know, Guanine pairs with Cytosine so they will have equal number of nucleotides.Therefore, number of Guanine = number of Cytosine = 150 ÷ 2 = 75

Answer:

As = 100

Ts = 100

Gs = 75

Cs = 75

during this blood also leaks and the colour of the lake changes

Answer:

In each instance, the variations in fish populations are subject to change due to the predation of larger fish on smaller ones. As a result, the surviving fish grow larger, akin to the manner in which the Megalodon can have hundreds of smaller fish within its body. This process can also result in the release of blood, which has the potential to alter the color of the surrounding water body.

Given what we know about biological processes, we can confirm that it does not in fact matter where the nutrients come from in terms of cellular respiration.

We consume food to provide the energy we need to function on a daily basis, for this, we may reach for an apple or opt for a candy bar. However, this is irrelevant on a cellular level. Cells do not eat the food the way that we consume them.

They use a process known as cellular respiration to change the food into energy to be used by cells. The most important of this process is the transformation of high-level sugars into simple sugars like glucose and other monosaccharides.

The force of the push is an unbalanced force.
The forces acting on the rock are balanced.
A weaker force of pushing would result in unbalanced forces.
The force of gravity is pulling the rock upwards.

The answer is that the forces acting on the rock are balanced.

Explanation: Basically since the object is not moving we can consider this system to have a net force of zero (where are forces are balanced).
