Imagine you are sitting with your leg at rest and free to move in all directions. An experimenter inserts an electrode into a mu

scle spindle stretch receptor neuron in one of your quadriceps muscles and excites (depolarizes) the cell, enough that its rate of action potential firing increases substantially. What will happen to that quadriceps muscle

The quadriceps muscles will contract.

Explanation:

Quardriceps are muscles of the thigh located in the front.

It is a group of four  vastus muscles named as-the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris.

Muscles posses the ability of contraction so an action potential that will excite the muscle cells will obviously result in contraction of the muscles.

So we can conclude that on depolarizing the muscle cell of the quadriceps will result in contraction of quadriceps.

Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?

Coastal Ocean!

Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.

This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.

NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.

Assume a hawk eats five 20 gram birds and one 150 gram rabbit. In terms of biomass, did the
inna [77]

Answer: the rabbit

Explanation:

In ecology, biomass refers to the mass of organisms living within a specific region at a time. Biomass is measured and usually described as:

  • the total mass of the organisms within a community
  • the average masses per unit area

Typically, more numerous organisms, such as producers, have a higher average biomass. This may include plants, animals or microbes such as bacteria and fungi. In terrestrial environments, biomass is distributed in pyramid form; the carnivorous hawk preys on rabbits and birds, which are nearer to the base of the pyramid- each predator population would have a lower biomass than its prey.

The birds weigh 100 grams while the rabbit weighs 150 grams.The rabbit has a higher total mass

Describe one piece of evidence that supports the big bang theory
Liono4ka [1.6K]

Answer:

The cosmic microwave background radiation.

This is completely consistent with a fireball event in which the radiation field was in thermal equilibrium, and is perhaps the most convincing evidence for the Big Bang.

How can a diet that is 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohy
jeyben [28]

Answer:

Due to increase or decrease in the concentration of carbohydrates have no effect on protein concentration.

Explanation:

A diet having 90% carbohydrates support the same amount of protein in the human body as a diet that is only 15% carbohydrates because with the increase or decrease of carbohydrates in the diet does not increase the amount of protein. Protein and carbohydrates are two different things, proteins broken down into amino acid that is utilize by the body for making muscles while carbohydrates are broken down into glucose that is used by the body for performing daily activities.
