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.
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

Explanation:
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
During mitosis two identical cells are produced from the parent cell these are called...
Answer:
Daugter cells
Explanation:
thses are called Daughter cells
Answer: Daughter Cells
Explanation: The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell. Meiosis has both similarities to and differences from mitosis, which is a cell division process in which a parent cell produces two identical daughter cells.

How many chromosomes are found in the common strawberry found in the grocery stores?
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
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 originated from Central and parental regions of the brain which is part of the cerebral cortex and they are refer to slow wave sleep. They can occur in the third stage of sleeping. They are deeply penetrated like drum beat and occur during deepest meditation and dreamless dream.

Question 4 of 25
What kind of molecule forms from polysaccharide chains that are very
strong?
O A. Protein
B. Cellulose
C. Monosaccharide
D. Lipid
SUBMIT
PREVIOUS
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.
Describe chemical changes and include 3 examples.
Answer:
These are all chemical changes you can pick which ever one you would like
Explanation:
Burning, cooking, rusting, rotting,food cooking, rust formation, tarnish forming on doorknobs, fuel burning for heat, tarnished penny.Fireworks explosion. Rotting bananas. Grilling a hamburger. Saliva digesting sugar with the use of amylase.
: Non living and living organisms have things in common o Fact: o Evidence:
Answer:
Things they have in common..
Explanation:
Non living things and living things are made up of matter.Both occupy spaceThe also have weight,colour,shape etcBoth Non living and living things are characterized by their type..Ants and aphids often live near each other the ants Feed on the waste produced by the aphids and the aphids are protected from predators by the presence of the ants what type of relationship is this
Answer: the answer is mutualism. please give me brainliest
Explanation: Mutualism is a relationship between two different species in which both species have benefits. In this example, ants benefit because they feed on aphids' wastes while aphids benefit because ants provide them protection.Jul 8, 2016

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
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.
