Could someone please help me with question 21

Answer:

The water cycle is an extremely important process because it enables the availability of water for all living organisms and regulates weather patterns on our planet. If water didn't naturally recycle itself, we would run out of clean water, which is essential to life.

Answer:

Often, people who prefer brown eggs do so because they believe brown eggs are more natural and healthy than white eggs. However, the truth is that all eggs are nutritionally very similar, regardless of size, grade or color (2, 6, 7). Both brown and white eggs are healthy foods.

Explanation:

Answer: no

Explanation:

Both types of the eggs have the same types of nutrients. White eggs and brown eggs are both nutritious. The answer to your question is no, white eggs and brown eggs have the same amount of nutrients.

Answer:

Ionizing radiation.

Explanation:

Mutation is the sudden change that is occur by exposing cells to the ionized radiation which change the genetic makeup of the cell. Due to mutation, the cell does not perform its normal function like before the mutation so when the mutation occurs in the cell, the genetic or DNA makeup is changed which make the environment unfavorable for the HIV virus and the virus can not cause any infection in the cell.

Answer:

Cytoplasm

Explanation:

Nucleus was my original answer but I'm actually wrong. It is not the nucleus.

B) cytoplasm

I am not 100% sure but i think it´s B

Answer:

movement; cell membrane; molecules; concentration; side

THIS IS know as diffusion

Explanation:

Diffusion is the movement of molecules from the side of the membrane with a higher concentration to the side of the membrane with a lower concentration. Facilitated diffusion is a process that occurs if the cell membrane is permeable to these molecules and if there exists a difference in the concentrations on the two sides of the membrane. This mechanism is also known as passive transport because no energy is needed for the movement of molecules across the membrane.

Answer:

False, they take a long time

Explanation:

Answer:

a

Explanation:

it is a because nematodes belong to a category of animals

Answer:

- temperature

- concentration gradient

- membrane permeability

Explanation:

the higher the temperature, the more kinetic energy the particles will have so they will move more quickly. the greater the concentration, the quicker rate of diffusion. when the permeability of the membrane increases the higher the diffusion rate.

hope this helps :)

1.The concentration of the two solutions. The bigger the difference of concentration between the two solutions, the bigger the rate of diffusion

2.The size of the molecules. The smaller the molecules the easier they diffuse

3.Temperature. If temperature increases molecules move faster.

Answer:not so goodly and smart

Explanation:

Answer:

Organisms such as hydra use regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.

Your drawing seems a little bit of so I hope I get it right!. I know that Relay neurons are found in the brain and spinal cord and allow sensory and motor neurons to communicate. Motor neurons are found in the central nervous system and control muscle movements.

Answer:

Bb and bb

Explanation:

The most likely genotypes of the parental generation would be Bb and bb.

If Bb and bb are crossed, such that:

                       Bb    x    bb

offspring:     Bb   Bb   bb   bb

Bb = 2/4 = 1/2 = 50%

bb = 2/4 = 1/2 = 50%

hence;

1/2 or 50%% of the offspring would express the dominant condition in the form of Bb and the remaining 1/2 or 50% of the offspring will express the recessive condition in the form of bb.

By checking whether they are infected or not by health check-up. Like their temperature, or probably blood test.

Or, if you are talking about precentage, usually its from the hospital that are reporting the number of people who are infected.

Answer: B. S cycle

Explanation: The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA.

Vertebrates are the only one with a backbone. And porifera is a sponge, which has a very basic body plan. It would be found there.

Answer:

Explanation:

DNA comes in long strands called chromosomes, which are kept inside the nucleus of a cell. Every one of our cells has a nucleus with all of the DNA. Each cell is different not because of the bits of DNA in it, but because of the bits it uses to make things.

Each strand of DNA is made up by joining together nucleotides. There are four different nucleotides called adenine (A), thymine (T), cytosine (C) and guanine (G). If you could see the nucleotides in a strand of DNA it would look something like this: AACGTATTGACATAGGGGGGCCTACTTA

It is quite extraordinary that just four different nucleotides make up the code of every single living thing. The order that these nucleotides are in determines the difference between a brain cell, a toenail, a blood cell and whether or not we have a certain disease.

So if you wrote out the DNA sequences of two people and matched them up together, they would look almost exactly the same. There would be about 1 difference in every 100 nucleotides (it’s actually more like 1 in 1000). These differences determine whether you have blonde hair or brown, whether you are tall or short, whether you will have asthma or not.

You are more similar to people you are related to because your DNA came from the same place; your great, great, great grandparents, or something like that. Your DNA is a combination of your Mum and Dad’s DNA, half from each. So you are half the same as your Mum, half the same as your Dad. If you looked at the DNA of a friend you are not related to, they would also be half the same as their Mum, and half the same as their Dad, but they would be quite different to you. This is because the last common ancestor (person who is related to you both) was so many hundreds or thousands of years ago, that a lot of changes have occurred in the DNA sequence since then.

When the given type of mutation happens, the round shape of the R.B.Cs changes from a round shape to a sickle-like shape. This condition is known as sickle shape anemia.

Sickle-shaped anemia is a genetic disorder. In this disease, the shape of the red blood cells changes to sickle-like. The red blood cells of sickle shape are not healthy. They die early and easily. This condition causes a shortage of healthy red blood cells. The symptoms are low red blood cells, block blood flow, pain in the body, dizziness, joint pain, blurred vision, and headache.

Patients who suffer from that condition are likely to have episodes of pain. This is known as a vaso-occlusive crisis. The pain can last from one week to two weeks.
