Explanation:

If the entire square is shaded and that 24m being the measurement of just one side just multiply 24 by 24 which is 576[tex]m^{2}[/tex]

If you are saying that 24 is the length of all of the sides combined just divide 24 by 4 to get one side and square it. 6 times 6 and you get 36[tex]m^{2}[/tex]

If a plant cell needs energy for endocytosis, what does it use and where does the energy come from?​

Answers

Explanation:

Active transport uses energy stored in ATP to fuel the transport. ... Endocytosis methods require the direct use of ATP to fuel the transport of large particles such as macromolecules.

Hope this helps!

If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.

Endocytosis is an energy-using process by which cells internalize molecules by engulfing them.

Endocytosis needs to use directly ATP to fuel the transport of large particles such as macromolecules, parts of cells that can be engulfed by other cells in a process called phagocytosis.Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e., moving from a low concentration to a high concentration and this uses cellular energy.

Thus, If a plant cell needs energy for endocytosis, its use and energy come from- Active transport from ATP.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) feathers and chicken with white (WW) feathers if the color is determined by alleles that show codominance. The heterozygote is an erminette chicken, which is black and white speckled.

Answers

Answer:

Please find the punnet square to this question as an attachment

F1 generation:

genotype = BW

Phenotype = Erminette offsprings

F2 generation:

genotype = BB (1): BW(2): WW(1)

Phenotype = 1 Black, 2 Erminette, 1White

Explanation:

This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).

According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)

Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:

Genotypic ratio = BB (1): BW(2): WW(1)

Phenotypic ratio = 1 Black, 2 Erminette, 1White

Answer:

an estuary

Explanation:

A wetland which contains a mixture of fresh water and salt water is called as an estuary. Thus, the correct option is A.

What is an estuary?

An estuary is an example of a partially enclosed, coastal water body where the freshwater from rivers and streams mixes up with the salt water from the ocean bodies. Estuaries, and their surrounding lands, are the places of transition from the land area to the sea area.

Estuaries and their surrounding wetlands are the bodies of water which are usually found where the rivers meet the sea. Estuaries are the home to many of the unique plant and animal communities which have adapted to the brackish water, which is a mixture of fresh water draining from the land and the salty seawater.

Radiation has a potential of causing germ cell mutations that may be passed on to future generations.

Explanation:

i think so, hopefully this helps;(

Ionizing radiation damage cells and cause double-strand breaks that let more DNA in. These additional fragments of DNA find their way to the nucleus and cause cellular mutations. Protective gears are worn to prevent this.

What are X-rays ?

X-rays are a form of electromagnetic wave radiation. Using X-ray imaging, your body's interior can be visualized. The photos depict the various bodily parts in various shades of black and white. This is due to the fact that various tissues absorb radiation in different ways.

Ionizing radiation, a type of radiation that x-rays create, has the ability to destroy living tissue. This is a risk that gets worse the more exposures someone has over the course of their lifetime. However, exposure to radiation normally carries a low risk of acquiring cancer.

Therefore, protective gears are worn during x-rays to avoid mutations.

Answer:

The correct answr is - A. Part of one chromosome attached to another chromosome.

Explanation:

Translocation is one of the chromosome abnormality that cause change in the number of the chromosome. In the translocation a part of the chromosome breaks off and bind or attached to the another chromosome.

The translocation cause various disorderes in individual one of them is Down syndrome which is the result of the alteration of chromosome number 21. In this translocation or specicifically the chromosome portion of chroromosme 14 breaks off and reattaches to the chromosome 21 result in one normal 14 and two normal 21 chromosme so there is trisomy occurs.

Answer:

A duplicated chromosome failed to separate (nondisjunction)

Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue.

What is protein?

It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10,000 different proteins make you what you are and keep you that way.

Protein is made from twenty-plus basic building blocks called amino acids.

Because we don’t store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—known as the essential amino acids, must come from food.

Therefore, Protein is found throughout the body—in muscle, bone, skin, hair, and virtually every other body part or tissue.

Since they belong to certain areas or zones that, due to their geographical characteristics, share a climate, vegetation, and wildlife, biomes provide the primary support for the harmony of nature.

Any biome can include a wide range of habitats because the term "biome" is more general than "habitat." An area's climate and geography determine the biome classification. Communities that have adapted to the unique climate and ecology of the biome make up each one. Depending on the surroundings, they come in a variety of forms. The temperate deciduous biome is the ideal environment for human habitation.

Explanation:

because you having digestive have nothing to do with your oxygen and breathing  

Problems with the digestive system make it very difficult for the body to digest enough food, and it is harder to exercise with digestion problems like this because cells would not work as well because they would not have enough glucose molecules, which is the last option.

 

What is the function of the digestive system during exercise?

Exercise is important for the body, and the digestive system plays an important role in it because the digestive system breaks down the food, and then the simplified food enters the blood and is then taken up by the cells for the different activities. If there are any issues with the digestive system, the food will not be well absorbed into the cells, and no energy will be produced for the exercise.

Hence, the answer is that cells would not work as well because, even though they would have enough oxygen molecules from the air, they would not have enough glucose molecules from food. The last one is the true fact.
