What happens to the actin and myosin during a muscle contraction?

Answers

Answer:

Once the myosin-binding sites are exposed, and if sufficient ATP is present, myosin binds to actin to begin cross-bridge cycling. Then the sarcomere shortens and the muscle contracts. In the absence of calcium, this binding does not occur, so the presence of free calcium is an important regulator of muscle contraction.

What was the result of using drainage blocks to keep water in the field level during the growing season?

Answers

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).

In a typical mammalian cell, what is the average percentage of total cell weight for protein and dna?

Answers

Answer:Protein is evaluated at ≈55% of the cell dry weight, followed by RNA at ≈20%, Lipid at ≈10% and DNA at ≈3% (the rest being polysaccharides, metabolites, ions etc.).

Explanation:

A typical mammalian cell averages 18% protein and 0.25% DNA by weight composition.

According to research, a typical mammalian cell is made up of water, ions, and macromolecules such as proteins, lipids, DNA, RNA, carbohydrates, and some miscellaneous metabolites.

The water component of a typical mammalian cell is about 70%, 18% proteins, 1% inorganic ions, 3% small metabolites, 5% lipids, 0.25% DNA, 1.1% RNA, and 2% polysaccharides.

A botanist wants to see how different colored light waves influence the growth of pea plants. She puts the same number of seeds into three identical pots with the same kind and amount of soil.she then gives them the same amount of water every three days for the length of the experiment. One pot is placed into a dark windowless closet. Another pot is left on the windowsill,and the third is placed under a lamp with a green bulb.she records the height of each plant every day for three months.


What is the independent variable in this experiment?

Answers

Answer:

The amount of light they receive.

Explanation:

In an experiment, the independent variable is the part of the experiment that the experimenter changes. In this experiment, the only thing that's different for each of the plants is the amount of light they receive. Everything else is the same - the same amount of soil, same amount of water, same pots, and so on.

The independent variable in this experiment is the amount of light received by each plant.

What is an independent variable?The experimenter manipulates or alters the independent variable, which is expected to have a direct effect on the dependent variable.For example, here the amount of light given to each plant is different and will have an effect on the growth of pea plant.In an experiment, the dependent variable is the variable that is being tested and measured, and it is 'depending' on the independent variable. here the growth of pea plant is dependent variable.

What were the ancestors of mitochondria according to the endosymbiotic theory?

A. Aerobic eukaryotes

B. Aerobic bacteria

C. Anaerobic bacteria

D. Chloroplasts

Answers

Answer:

d is your answer

Explanation:

Ancestors of Mitochondria were aerobic bacteria, according to endosymbiotic theory.

What is endosymbiotic theory ?

According to Lynn Margulis' endosymbiotic theory, mitochondria in eukaryotes are thought to have originated via an endosymbiotic connection with purple photosynthetic bacteria around 1.5 109 years ago. The endosymbiont, which had been captured, was subsequently transformed into a useful organelle bound by two membranes. Supporting data for the endosymbiont theory.

Prokaryotic cells and mitochondria are the same size. The DNA found in mitochondria is structurally identical to bacterial DNA. Similar to bacteria, mitochondria are self-replicating cells divide by binary fission Two membranes enclose mitochondria, and the inner membrane is structurally very similar to that of bacteria.

Therefore, aerobic bacteria are the ancestors of mitochondria.

A. -experiencing sunrise and sunset.
B. -closest to and farthest from the Sun.
C. -halfway between the Sun and the Moon.
D. -closest to and farthest from the Moon.

Answers

I think it’s C I’m not really sure

High tide is occurring on the sides of the Earth that are closest to and farthest from the Moon. The correct option is D.

What is high tide?

When the sea or a river reaches its greatest level and moves the farthest up the beach or the bank, it is said to be at high tide.

The gravitational forces that try to pull the water away from the moon are resisted by the water that is travelling away from the moon.

On the far side of the Earth, where the moon's gravitational pull is weaker, inertia triumphs, the ocean swells, and high tide happens.

The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.

High tide is when the wave's highest portion, or crest, reaches a specific area; low tide is when the wave's lowest portion, or trough, happens.

Thus, the correct option is D.
