what part of the cellular respiration pathway is affected by cyanide?
The ferric ions' cytochrome oxidase in the mitochondria makes a reversible chemical bond with cyanide. By preventing the conversion of oxygen to water, this essentially stops cellular respiration.
What is the role of cyanide in cellular respiration?Heme-containing proteins include Fe3+, which cyanide binds to. As a result, the electron transport chain's terminal cytochrome complex IV is inhibited.
Cyanide's blockade of complex IV depletes ATP, which leads to cell death.
Because the molecules are so small and can disperse quickly throughout the entire body, cyanide can kill so quickly by damaging all major organs and tissues in a short period of time.
Therefore, electron transport system is affected by cyanide in cellular respiration.

Which of the following is not a lipid?
Asteroid
B cholesterol
C
wax
D cellulose
Answer:
cellulose
Explanation:
lipids are fats oils or waxes. cellulose is a fiber
Answer:
cellulose
Explanation:
Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein. Therefore waxes are not the answer.
Steroids are lipids because they are hydrophobic and insoluble in water, but they do not resemble lipids since they have a structure composed of four fused rings. Cholesterol is the most common steroid and is the precursor to vitamin D, testosterone, estrogen, progesterone, aldosterone, cortisol, and bile salts. Therefore steroid and cholesterol is not the answer.
How do differences between the peaks and valleys of the two graphs demonstrate interactions between these populations?
Answer:
peaks and valleys show population increase and decrease between 2 species or more.
Explanation:
the peaks and valleys are used to show predation hence if there is an increase in prey there will be an increase in the predators and if there is a decrease in prey there will be a decrease in predators therefore creating peaks and valleys in that graph hence demonstrating population interactions between the two species.
From the types of light that reach Earth's surface, which do you think could be causing skin cancer?
Explain your reasoning.
The type of light that could cause skin cancer is the ultraviolet (UV) light rays. The following reasons are further explained why they harm the skin.
What is ultraviolet (UV) light?The ultraviolet light is a type of electromagnetic radiation that possess a shorter wavelength than the visible light.
The solar radiation from the sun that reaches the earth planet is made up of the following:
visible light,Infrared rays andultraviolet light rays.The ultraviolet light is harmful to the skin when exposed to it for a long time. This can damage the DNA of the skin cells which can lead to abnormal proliferation or uncontrolled growing of the cells which eventually causes cancer.
Therefore, the type of light that could cause skin cancer is the ultraviolet (UV) light rays.

because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called
Because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called semiconservative.
Replication is the process by which a DNA molecule generates two identical to itself, and is key in cell reproduction.
All cells in the body must have the exact same genome (as in asexual reproductive organisms, which are practically clones of each other) and this is achieved through replication.
The process consists of separating the two strands of DNA, each of which will function as a template to synthesize a new one.
That is, each of the two strands of DNA serves as a template to synthesize a new complementary strand of the template.
In the end, two DNA molecules are formed, each of the two DNA molecules has a new chain and one original strand, this mode of replication is called semi-conservative.
Therefore, we can conclude that because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called semiconservative.

What do you think is the more ethical and feasible approach to wildlife preservation: change human behavior to limit human impact, or create sanctuaries to preserve some of the threatened animals’ population? Why?
Answer:
I think we need to do both, but I'll let you decide which you think sounds better for you personally (personally I think sanctuaries are often more effective).
Explanation:
Behavior changes It is not really ethical to continue to have a negative impact when changing our behavior can help, however, this may not be ideal as explained below
Sanctuaries It is often more feasible to create preservation sanctuaries because 1) it is hard to get everyone to change enough habits in order to create large-scale change and 2) some species require more immediate action to save, whereas changing human behavior may not be enough and/or at the right pace to preserve and expand the populations of endangered populations
Depending on the main threat to a specific population, the approach will obviously be different.

If an experiment was being conducted using an enzyme that was very sensitive to changes in pH (which could result in denaturation), what should be added to the experiment to prevent the enzyme from denaturing?
A. a buffering solution
B. extra substrate
C. an acid
D. a base
Answer:
maybe the answer is C..sorry if i wrong
If an experiment was being conducted using an enzyme that was very sensitive to changes in pH, a buffering solution must be added in order to prevent the enzyme from denaturing. Thus, the correct option for this question is A.
What is the denaturation of an enzyme?The denaturation of an enzyme may be defined as a process through which a molecular structure of an enzyme gets deviate from its original state due to exposure to high temperature, pH sensitivity, etc.
The function of a buffering solution is to stabilize the pH of the given solution. It helps the other component of the solution to resist in response to pH change. A Buffer solution is capable to neutralize the effect of the small amount of acid or base.
Therefore, a buffering solution must be added in order to prevent the enzyme from denaturation. Thus, the correct option for this question is A.

“The movement of cytoplasm is due to the movement of chloroplasts in the living cells of onion plant”, “while the movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants”
which statement is correct and which one is wrong
''The movement of chloroplasts is due to the movement of cytoplasm in the living cells of bean plants'' is the correct statement.
The above statement is correct because chloroplast is an organelle which moves in the cell through the medium known as cytoplasm. Cytoplasm is a thick fluid that fills every type of cell and organelles are floating as well as suspended in this fluid.
All organelles such as the nucleus, endoplasmic reticulum, chloroplast and mitochondria etc are located in the cytoplasm. The portion of the cytoplasm except the organelles is called cytosol so we can conclude that chloroplast is an organelle which moves within the cell with the help of cytoplasm.
