Answer:
X in the diagram represents the cell membrane and performs the function of regulates the transport of materials.
Explanation:
The cell membrane, marked with X in the diagram, is a lipid bilayer with hydrophobic properties, which acts as a semi-permeable membrane to the passage of substances.
This membrane, that covers the cell and keeps it isolated from the extracellular space, has the function of controlling or regulating the passage of materials from the extracellular to the intracellular space, as well as the exit of substances from the interior of the cell. To fulfill this function it has several alternatives of transmembrane transport.
The other options are not correct because:
The cell membrane does not control the energy released. Protein synthesis occurs in the rugged endoplasmic reticulum. Cellulose synthesis occurs inside the cell, a process dependent on photosynthesis.Answer: it regulates the transport of materials

What human body response help maintain homeostasis?
Answers
Answer:
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted.
Explanation:
Answer:
If a raise in body temperature (stimulus) is detected (receptor), a signal will cause the brain to maintain homeostasis (response). Once the body temperature returns to normal, negative feedback will cause the response to end. This sequence of stimulus-receptor-signal-response is used throughout the body to maintain homeostasis.

•contractile vacuoles in unicellular eukaryotes and small storage vacuoles in plant cells
•food vacuoles in amoebas and lytic vacuoles in plants that contain hydrolyzing enzymes
Answers
Answer:
I believe it is the second answer, contractile vacuoles and central vacuoles.
Explanation:
Contractile vacuoles store water, and so do the central vacuoles in plant cells. They regulate water in the cell and both are typically large.

Describe how skin pigmentation is determined, and also
how it is affected by exposure to the sun.
Answers
Answer:
pigmentation is determined by the amount of melanin in the skin. Without melanin, the skin would be pale white with shades of pink caused by blood flow through the skin. The extra melanin makes your skin look darker or sun-tanned. In some cases, the sun causes an uneven increase in melanin production, which produces irregular coloring of the skin. The sun can also cause a permanent stretching of small blood vessels, giving your skin a mottled, reddish appearance.
Explanation:
A yellow cat is crossed with a black cat. You know that the black and yellow fur color traits are carried on the X chromosome and only one X chromosome is expressed in a cell. You observe that half the offspring are calico (patches of black and yellow) and half are black. Your friend Tien tells you that the black cat was the mother, the yellow cat was the father, and all the calico kittens are females. Is he correct? Write out all the possible crosses to test his answer.
Answers
Answer:
Tien is correct with his answer that all the calico kittens are females.
The reason and the possible crosses to test the answer are given below
Explanation:
First of all, the coat color in cats is hugely decided by the sex-linked X chromosome in the female. This X chromosome found in cats makes cats exhibit codominant traits. The calico cat is a blend of black and yellow patches. To be considered calico, a cat must carry an allele for the black color and an allele for the yellow color.
The male is no heterozygotes and since the Y- chromosome in the male doesn't affect the result of the coat color in the offspring, there has to be a rare genetic disorder that will result in a calico kitten that is male.
The possible crosses to test his answer:
Cross 1:
If the black cat was the mother her genotype would be: Xb Xb
If the yellow cat was the father his genotype would be: Xy Y
The possible offspring from the cross would result in:
XbXy XbY XbY XbXy ( where XbXy are calico females and XbY are black males)
Cross 2:
If the yellow cat was the mother her genotype would be: Xy Xy
If the black cat was the father his genotype would be: Xb Y
The possible offspring from the cross would result in:
XyXb XyY XyXb XyY (where XbXy are calico females and XyY are the yellow males)

Answers
Nutrient cycle is also known as the cycle of matter. Nitrogen, water and carbon all three are cycle of matter but energy cycle is not. Thus, correct option is B.
What is Nutrient Cycle?
Cycle of matter are also known as Biogeochemical cycles. These cycle include both biotic and abiotic factors. Cycle of matter are described into five types based on matter: a. water cycle, b. nitrogen cycle, c. phosphorus cycle, d. sulfur cycle, e. carbon cycle.
Matter constantly moves in the cycle involving change in the state. The matter cycles are essential as they recycle important nutrients required for the survival of living organisms.
In contrast to this, energy flows in the atmosphere. It is the interaction between the energy sources within Earth. The interaction between energy sources and Earth's atmosphere is very significant and a small change could lead to significant change in climate behavior of an area.
Therefore, the correct option is B. Energy cycle is not a cycle of matter.

First exclude the four that are correct. While performing photosynthesis during the day, the chloroplasts of a green leaf produce ATP to be used in the Calvin cycle. ATP as an energy source for the roots of the plant. sugars for the green leaf’s cellular respiration at night. sugars as an energy source for the roots of the plant. sugars to fuel the growth of the plant.
Answers
Answer:ATP as an energy source for the roots of the plant.
Explanation:
Photosynthesis is the process by which plants manufacture their own food. It involves the combination of water and carbon dioxide in the presence of sunlight. Sugars are produced in the process.
The ATP molecules produced during photosynthesis are not transported to plant root cells. Rather, metabolic activities within the plant root cells produces the energy molecules required by the plant roots.

The spleen and the thymus work together to fight infection. These organs together make up immune system.
What is immune system?The immune system defends the organism's body against external invaders. Toxins and germs such as bacteria, viruses, and fungi are examples of these (chemicals made by microbes).
The immune system is made up of various organs, cells, and proteins that collaborate.
The thymus and bone marrow, lymph nodes and vessels, spleen, and skin are all vital to the immune system's proper functioning.
The spleen filters and stores blood, as well as producing white blood cells to fight infection or disease.
The thymus gland is located in the upper chest, beneath the breast bone. It is responsible for the maturation of a specific type of white blood cell that fights off foreign organisms.
Thus, immune system encompasses spleen and thymus.

Answers
Answer:
The enzyme will no longer be able to catalyze the reaction with the substrate
Explanation:
Enzymes usually have a very specific structure than holds the substrate molecules, facilitating the optimal environment for the reaction to proceed. This reduces the activation energy required to start the reaction.
If the shape changes, the substrate molecule will no longer properly fit. Therefore, the enzyme will not be able to catalyze the reaction.
