You have isolated a highly lethal toxin from an octopus that you have reason to believe binds with high affinity to the pore opening of a voltage-gated sodium channel. To determine the effect of toxin binding, you perform a _______ experiment.

Answers

Answer:

To determine the effect of toxin binding, you perform a Competitive Binding Experiment

Explanation:

Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.

They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.

They are important because:

1. Validate a direct binding assay

2. Confirm whether or not a drug binds to the receptor

3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects

Why is meiosis important for organisms?
It creates gametes and allows for genetic variation among organisms.
It produces genetically identical cells.
0 It provides a means of asexual reproduction.
O It allows for cell and tissue repair

Answers

The correct answer is A. It creates gametes and allows for genetic variation among organisms.

Meiosis is the process of cell division in which a single cell divides into four daughter cells. The genetic constitution of the daughter cells reduces to the half as compared with the parent cells. While crossing over, an exchanging of genetic material is passed between chromosomes and that allow variations to happen.

what are two abiotic factors that might account for the differences in productivity among the land ecosystems in the table?


The factors in an ecosystem that are considered abiotic, or nonliving, are very important to the primary productivity of the ecosystem. Those factors are both chemical and physical, and include light (radiation), temperature, water, atmospheric gases, and soil. Climate generally influences all the abiotic factors.

How many chromosomes are found in the common strawberry found in the grocery stores?​

Answers

But figuring out where those genes were located was like finding a treasure in a hall of mirrors: Unlike humans, which have just two copies of each of our 23 chromosomes, strawberries have a whopping eight copies of seven chromosomes, for a grand total of 56.

Answer:

In total, they have 56 chromosomes

Explanation:

Unlike Humans which has two copies of 23 chromosomes (in total 46) common strawberries have 8 copies of 7 chromosomes hence why they have a total of 56 chromosomes.

Which type of brain wave originates in the central and pariental regions of the brain and is associated with normal sleeping

Answers

Answer:

Delta waves

Explanation:

This is because Delta waves are the slowest brain waves and they have they highest amplitude and these waves are responsible for normal sleep.

They are deeply penetrated like drum beat and occur during deepest meditation and dreamless dream.

9. Doctors tested a patient to find out what molecules were in her cells. Her cells contained normal
levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules
Will this patient be able to exercise normally?
a
Yes, as long as her cells have enough oxygen, her body will be able to exercise,
b
No, her cells need glucose to react with oxygen to release enough energy to exercise.
С
No, her cells need amino acids to react with oxygen to release enough energy to exercise.
d
No, her cells need glucose to react with amino acids to release enough energy to exercise.

Answers

Answer:

b. No, her cells need glucose to react with oxygen to release enough energy to exercise.

Explanation:

Living organisms are able to perform any of their day-to-day activities due to the release of energy in their individual cells. The process by which this energy is obtained by their cell is called CELLULAR RESPIRATION. Cellular respiration is the process whereby glucose (from digested food) is broken down in the presence of oxygen to yield energy in form of ATP. The general equation is as follows:

C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 + 6H2O + ATP

According to this question, a doctor is said to test a patient for the content of molecules in her cells. Her cells were found to contain normal levels of oxygen molecules, low levels of amino acid molecules, and low levels of glucose molecules. This patient will NOT BE ABLE to exercise normally because her cells need glucose in optimal amount to react with oxygen to release enough energy to exercise.

How does energy move through living systems?

A. Energy can be created by organisms and can be passed on if it is not used by that organism

B. All of the energy is used up by organisms as they move, grow and reproduce so less energy is available for the next organism in the food chain

C. Energy is transformed and/or lost as heat as it passes from one organism to the next, but the total amount always stays the same

D. Energy is created during photosynthesis

Answers

Answer:energy is produced during photosynthesis. energy is used by the photosynthesiser or lost as heat, with the remainder available to the next organism in the food chain.

Answers

Answer:

B. Cellulose

Explanation:

Polysaccharide are substances that contains many units of monomers called MONOSACCHARIDE. They are carbohydrate molecules consisting of very long chains of monosaccharides like glucose, galactose etc.

An example of molecule that forms from strong chains of polysaccharides is CELLULOSE, which consists of long chains of glucose units linked together by B-1,4-glycosidic bonds. Cellulose is the most abundant polysaccharide on Earth found in plant cell walls.
