The diagram shows that a cottontail rabbit gained 400 KJ of energy when it consumed a plant. The cottontail rabbit was later eaten by a barn owl, but the owl only gained 50 KJ of energy from consuming the rabbit. Which statement best explains why only 50 KJ of energy was passed on to the barn owl?
Answer: The total energy passed from one level to the next is only about one-tenth of the energy received from the previous organism. This means that an animal eating a plant will only get about ten percent of the energy that is stored in the plant
Explanation: it may be lost as faeces, thermal energy or may not be digested properly to get the derived energy

The diagram below represents one way an enzyme can be inhibited (stopped).
Which statement explains the effect of an inhibitor on an enzyme?
The substrate will not be able to attach to the enzyme's active site.
O The enzyme will likely be attacked by immune cells.
Answer:
The answer is The substrate will not be able to attach to the enzyme's active site.
Because the function of inhibitors is to block the enzyme's activity
Explanation:
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT
The substrate will not be able to attach to the enzyme's active site. So the correct option is A.
What is an enzyme inhibitor?The inhibition is carried out by inhibitors that do not advance the product's development. The inhibitors may affect the enzyme as well as the substrate. Enzyme inhibition is the term used to describe the cessation of enzyme activity.
These enzyme inhibitors can bind to active regions and prevent further action by stopping it. Both reversible and irreversible forms of binding are possible. The ability of an inhibitor to block an enzyme may be irreversible or reversible depending on its unique function. Enzyme inhibitors can block the binding site, which reduces the enzyme's catalytic activity by preventing the substrate from binding to the active site.
Reversible inhibitors bind to enzymes by non-covalent interactions such as ionic bonds, hydrogen bonds, and hydrophobic contacts. Reversible inhibitors do not conduct chemical reactions when they are linked to an enzyme and are quickly removed by dilution or dialysis.
However, irreversible inhibitors usually covalently change an enzyme, making it impossible to reverse inhibition.
Therefore, the correct option is A.

Here is a Answer to your question:
Mitochondria
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Why can’t penguin fly?
Answer:
No they cannot fly
Explanation:
Penguins dont have any feather to fly with
Answer:
Well, in a sense they really do fly, only through the water, not through the air. Their wing bones are fused straight, making the wing rigid and powerful like a flipper. Penguins don't really need to fly because they dive deep, and swim so that they can catch their prey. Their bodies have huge fat supplies, heavy muscles, and densely packed feathers. There’s no way they could fly with such short wings and heavy bodies.

Which of these is a benefit of fish farming?
A. It poses a risk of disease for wild stocks.
B. It depletes fish populations.
C. It eases the demand on commercial fisheries.
D. It pollutes natural bodies of water.
Answer:
C
Explanation:
It's pretty simple really, just find the Benefit. Pollution is definitely a harmful effect, disease is also not a benefit, and depletion of fish population is bad, so easing demand on commercial fisheries is the answer
Which of the following is a distinction between the Krebs cycle in eukaryotes and prokaryotes?
A. Prokaryotes do not use acetyl CoA.
B. The process occurs in the cytoplasm of Eukaryotes.
C. The process occurs in the mitochondria of Eukaryotes.
D. Eukaryotes do not produce carbon dioxide.
E. Prokaryotes do not produce FADH2.
Answer:
C. The process occurs in the mitochondria of Eukaryotes.
Explanation:
In eukaryotes: glycolysis takes place within cytosol, Krebs cycle within mitochondrial matrix & ETC within inner mitochondrial membrane. Prokaryotes undergo binary fission(only cytokinesis) & conjugation.Prokaryotes undergo binary fission(only cytokinesis) & conjugation. Eukaryotes perform mitosis, meiosis(both karyokinesis and cytokinesis).Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.
Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.

B. A neuron synapses with another neuron via a neurotransmitter.
C. Eye muscles constrict in response to light.
D. Secretion of TSH stimulates the secretion of thyroxine.
E. The maternal parent induces spontaneous expression of recessive genes.
Answer:
A
Explanation:
A
How does the ectoderm that will make up the future eye know to develop into an eye? The cells are "told" to develop into an eye because the nearby retina releases chemical signals that direct the development of the cells. This process is called induction. Choice A depicts a similar situation. The notocord releases chemical signals that tell the overlying ectoderm that it is time for it to become the neural tube. None of the other choices depict the process of induction.
