Answer:

The answer should be A. lithosphere.

Explanation:

Firstly, let's look at the options:

C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.

B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.

Therefore, finally, we have A as the answer.

(As a sidenote, the "lithosphere" means the Earth's crust.)

Hope this helped!

The lithosphere contains the tectonic plates, so that’s the answer.

3. On a particular planet, it takes 850 J for a 50 kg remote probe to launch
itself up 2 m. What is the gravitational field strength on the planet?

Answers

Answer:

the gravitational field strength is 8.5 N/kg .

Explanation:

PE = mgh

where,

PE is Potential Energy

m is the mass

g (a) is the acceleration

h is the height

Substitute the value we get

→ 850 = 50×a × 2

→ 850 = 100×a

→ a = 850/100

→ a = 8.5m/s²

Acceleration is 8.5m/s².

Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?

Answers

Answer:

Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.

What prevents acetylcholine from accumulating in the neuromuscular junction and causing a sustained contraction in a normal individual

Answers

Answer:

Botulinum toxin

Explanation:

Botulinum toxin is known to hinder the release of acetylcholine into the synaptic cleft at the neuromuscular junction.

This leads to acetylcholine not attaching to its receptors and eventually leading to the inability to have muscle contractions.

Hence, in this case, the correct answer is Botulinum toxin prevents acetylcholine from accumulating in the neuromuscular junction in individuals.

What are the charges both inside and outside of the neuron before you click the stimulate neuron button?

Answers

Answer:

The correct approach is "Negative and Positive".

Explanation:

Just outside of the neurons, the electrostatic interactions seem to be extremely favorable or positive (+) as well as the ion mostly with the greatest proportion was indeed sodium. Throughout intracellular space, a large amount of protein would be negatively charged, or even just potassium channels predominate. Under those same circumstances, the ion channels also seem to be inaccessible.

For this specific purpose, this same lying down the neuron, before obtaining a stimulus, introduces positively charged on the external social but instead negative (-) inside though.

Answers

Answer:

B) presence of a nucleus

Presence of a nucleus will be most helpful in classifying a cell as either prokaryotic or eukaryotic. So, the correct option is B.

What are Prokaryotes and Eukaryotes?

Prokaryotes are defined as those organisms which possess cells that lack membrane bound organelles. These are usually single cell organisms. Some examples of prokaryotes include bacteria, archaea, and cyanobacteria (blue-green algae).

Eukaryote are defined as those organisms which possess membrane bound organelles. These contain a central nucleus which is surrounded (bound) by a membrane called nuclear envelope. Some examples of eukaryotes include animals, plants, fungi, and protists.

Thus, the presence of a nucleus will be most helpful in classifying a cell as either prokaryotic or eukaryotic. So, the correct option is B.

A) centrosomes
B) ribosomes
C) actin
D) A and B only
E) A, B, and C

Answers

Answer: D) A and B only

Explanation:

Centrosomes and Ribosomes are both present in the animal cell with both of them having different roles. Centrosomes have roles in cell divisions as they maintain chromosome number during the process and Ribosomes are in charge of the synthetization of proteins.

These two share a role together which is that they are both needed by the cell in order to form either cilia or flagella.

If the frequency of the disorder in the population is 0.0070, what is the percentage of heterozygous carriers

Answers

Answer:

15.322 %

Explanation:

Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:

p² + 2pq + q² = 1, where

1- the genotypic frequency of the homo-zygous dominant allele is p²,  

2- the genotypic frequency homo-zygous recessive allele is q², and

3- the genotypic frequency heterozygous allele is 2pq  

Therefore:

q² = 0.007 >> q = √ 0.007 = 0,0836  

p = 1 - q = 1 - 0,0836 = 0.9164

2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)
