The formulas that will be used are:

Situation one:
The moon will be experiencing gravitational force in the form of centripetal force, so we equate the two formulas.

Gravitational force = GMm /r²
Centripetal force = mv²/r

Equating,
GMm/r² = mv²/r
v² = GM/r

The first scenario will use the formula v² = GM/r


Situation 2:
The second situation will use the simple distance over time formula for velocity, where the distance will be the circumference and the time will be in seconds.

v = 2rπ/t

Most of the oxygen exiting the blood and entering the tissues does so from the capillaries.

Answer: Option D

<u>Explanation:</u>

The circulatory system consists of the heart, arteries, veins and capillaries. An artery is the one which carry blood from the heart to the organs. A vein is the one which carry blood from the organ to the heart.

A capillary is the smallest blood vessel which helps connect the functions of arteries and veins in the body. The capillaries are the narrow tubes which allow diffusion of Oxygen into and from the tissues. It’s prior function is to drop Oxygen in a tissue and collect the Carbon dioxide from the tissue.

You are a wildlife biologist. You think the best way to protect the selkirk caribou is to use the same technique that saved the
larisa86 [58]

Answer:

Controlling the predator population, wolves.

Explanation:

The method followed for the little smoky herd protection was to control their habitat and the population of the predators in the said habitat, which were wolves.

If I recommend the same method as the best way to protect the selkirk caribou, then i would be suggesting controlling the population of the predators in the area, which are mostly wolves, and in this way protecting the population of the selkirk caribou.

I hope this answer helps.

Photosynthetic and chemosynthetic organisms can be called primary producers because they make their own food?
LenaWriter [7]

Heterotrophs are organisms that must consume food from other organisms because they are unable to synthesize their own food molecules.

<h3>What is heterotrophs?</h3>
  • An organism is referred to be a heterotroph if it is unable to manufacture food on its own and must obtain it from other sources of organic carbon, primarily plant or animal materials.
  • Heterotrophs are primary, secondary, and tertiary consumers in the food chain but not producers.
  • Because they eat producers or other consumers, heterotrophs are referred to as consumers.
  • Humans, dogs, and birds are all instances of heterotrophs.
  • In a food chain, a group of creatures that supply energy and nutrients to other organisms, heterotrophs occupy the second and third levels.
  • An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy.
  • Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition."
  • Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients.

It is also referred to as a license, certificate, card, or credentials. You get the point.

Cellular respiration involves two phases. The anaerobic phase does not involve oxygen, while the aerobic phase does. Where does
Alex

While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration occurs in the cytoplasm and mitochondria, respectively, of the cell.

<h3>What is cellular respiration?</h3>

The process through which food, in the form of sugar (glucose), is converted into energy within cells is known as cellular respiration. All kinds of cellular operations are then powered by the energy that is stored in ATP molecules.

There are three types of cellular respiration

1) Anaerobic respiration happens when there is no oxygen present.

2) Aerobic respiration occurs when there is oxygen present.
