what is the role of a receptor in helping an organism maintain homeostasis

Answers

Cellular junctions help organisms maintain homeostasis by connecting cells to their neighbors, thus enabling communication between cells. Receptors allow cells to respond to chemical messages.

The role of a receptor in helping an organism maintain homeostasis  is to detect stimuli and sends information to the control center. Thus, option C is correct.

What is homeostasis  ?

Any self-regulating mechanism by which biological systems have a tendency to retain stability while responding to environmental factors that are best for survival.

The body's homeostasis keeps all cell processes and enzyme activity at their ideal levels. Despite changes in internal and external conditions, it is the maintenance of a constant internal environment.

As an instance of homeostasis in a biological system, the regulation of body temperature in humans is a good example.

Therefore, the control center receives input from the sensory receptor or sensor. Option C is correct.

Where can the process of ketolysis occur?

Answers

Answer:

The precursors of ketone bodies include fatty acids from adipose tissue or the diet and ketogenic amino acids. The formation of ketone bodies occurs via ketogenesis in the mitochondrial matrix of liver cells.

Explanation:

Ketosis is a process that happens when your body doesn't have enough carbohydrates to burn for energy. Instead, it burns fat and makes things called ketones, which it can use for fuel


Ketogenesis occurs primarily in the mitochondria of liver cells. Fatty acids are brought into the mitochondria via carnitine palmitoyltransferase (CPT-1) and then broken down into acetyl CoA via beta-oxidation.

Pauline took two small identical containers and filled them with the same amount of water.She dissolved a tablespoon of salt in one of them and placed both containers in a freezer.Pauline then observed them every five minutes until one of them had frozen.What is most likely the dependent variable (outcome variable) in this experiment?

A.The time it took for the liquids to freeze
B.The amount of water in each container
C.The amount of salt in each container
D.The type of liquid

Answers

Answer:

A

Explanation:

This line should explain it "Pauline then observed them every five minutes until one of them had frozen."

The most likely dependent variable (outcome variable) in this experiment is the time it took for the liquids to freeze. The correct option is A.

What are the variables of the experiment?

The variables of an experiment are the factors of the object on whom the experiment is done or the factors which affect the experiment. There are three types of variables. These are dependent, independent, and control variables.

Independent variables are those which can not be controlled by the person who is doing the experiment. The dependent variables can be changed or controlled by the experimenter.

A controlled scientific experiment will be controlled by the scientist, and it is to be checked that what time and what face of the experiment is going on.

Therefore, the correct option is A. The time it took for the liquids to freeze.

Flouride is an inhibitor of glycolysis. Which enzymes are inhibited by Fluoride? Check all that apply.


pyruvate kinase


glyceraldehyde phosphate dehydrogenase


phosphoglucoisomerase


hexokinase


enolase


phosphoglycerokinase


phosphoglyceromutase


triose phosphate isomerase


aldolase


phosphofructokinase

Answers

Answer:

The answer is Enolase.

Explanation:

The reason why is because "Fluoride inhibits enolase, which is far downstream in the glycolytic pathway. Enzymes upstream of enolase remain active and continue to metabolize glucose until substrates are exhausted."

Fluoride is an inhibitor of enzyme enolase. Thus, the correct option is E.

What is Glycolysis?

Glycolysis may be defined as a process that involves the partial breakdown of glucose into pyruvate, a three-carbon compound by cells with the utilization of 10 sequential enzymes. It is also known as the Embeden-Meyerhoff pathway.

Fluoride functions primarily by inhibiting the enzyme enolase in the glycolytic pathway. This is because enzymes present in the upstream of enolase remain active and continue to metabolize glucose until substrates are consumed. This inhibition of the specific enzyme occurs in the presence of inorganic phosphate.

The enzyme enolase is responsible for the reversible conversion of phosphoglycerate to phosphoenolpyruvate and vice versa in the glycolysis pathway. It is present in the downstream part of the glycolysis process.

Therefore, Fluoride is an inhibitor of enzyme enolase. Thus, the correct option is E.

What process of DNA is represented in the diagram below?

Answers

Answer:

DNA Replication

Explanation:

Because DNA's two strands are complementary, it can reproduce itself. This means that one strand can serve as a template for the creation of the other. It occurs just prior to cell division via mitosis or meiosis, allowing each new daughter cell to have a full genome.

The two strands of DNA must first separate from one another before replication can begin. DNA helicase is an enzyme that breaks the hydrogen bonds that hold the two strands together, allowing them to separate.

Why do silver and copper have similar properties?
State your claim. Make sure your claim fully explains how two different materials can have similar properties.
Summarize the evidence you have gathered to support your claim and explain your reasoning. Type your response below and click submit in Schoology.

Answers

Answer:

These metals, especially silver, have unusual properties that make them essential for industrial applications outside of their monetary or decorative value. They are all excellent conductors of electricity. The most conductive (by volume) of all metals are silver, copper and gold in that order. Silver is also the most thermally conductive element, and the most light reflecting element. Silver also has the unusual property that the tarnish that forms on silver is still highly electrically conductive.

Copper is used extensively in electrical wiring and circuitry. Gold contacts are sometimes found in precision equipment for their ability to remain corrosion-free. Silver is used widely in mission-critical applications as electrical contacts, and is also used in photography (because silver nitrate reverts to metal on exposure to light), agriculture, medicine, audiophile and scientific applications.

Gold, silver, and copper are quite soft metals and so are easily damaged in daily use as coins. Precious metal may also be easily abraded and worn away through use. In their numismatic functions these metals must be alloyed with other metals to afford coins greater durability. The alloying with other metals makes the resulting coins harder, less likely to become deformed and more resistant to wear.
