Jackie was born with _____ , the absence· of long· wavelength cones .

1 answer:

8 0

PROTANOPE. These are the individuals that suffers form color blindness. This color blindness is due to the absence fo the L- cones which are cones that are sensitive to long wavelength. Cones are one of the three types of photoreceptos found in the retina. These are responsilble for color vision and function best in a brightl light. In contrast to the rods which works on dim light. Cones are found in the fovea.

The U.S. National research Council recommends that adults eat 0.8 g of protein daily per kilogram of body weight. What is the mi

faust18 [17]

Explanation:

For a man weighing 185 pounds his minimum daily protein requirement is 67.118 g of protein.

Proteins are integral to many bodily functions including cell growth,repair and as an alternative source of energy.

Further Explanation:

Large monomer chains form biological macromolecules that perform many essential body functions, including nucleic acids, carbohydrates, proteins, and lipids. These are organic molecules, meaning Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N), and phosphorus (P) are ringed or long-chain.

Proteins are structural support molecules consisting of long amino acid chains joined via peptide (CONH) bonds; these are 20 specific units arranged into several macromolecules. Amino acids are absorbed through digestion and incorporated into the cells of the body to form muscle organs that signal molecules and provide an alternative source of energy.

First... convert 185 pounds to kilograms. Pounds (lbs) can be a measure of mass or weight, while Kilograms (kg) are a measure of mass.
1 pound= apprx 0.4535 kilograms. ∴ 185 lbs = 83.8975 kg
Then, find the daily requirement for the person's mass in kg .....................0.8 grams (g) of protein is recommended per kg of body weight. ∴ 0.8 × 83.91 = 67.118 g

A 6,000 kg train car is moving to the right at 10 m/s and connects to a 4,000-kg train car that wasn't moving. What is the veloc

SIZIF [17.4K]

6 m/s

This type of collision is a Inelastic collision

Explanation:

We begin by finding the momentum of the initial train car;

Remember that momentum is given by the formulae mass (kg) * velocity (m/s)

Therefore;

Momentum = 6000 * 10

= 60,000 kg⋅m/s

The other car has zero momentum because;

4000 * 0

= 0

When the two train cars collide, the total momentum will be;

60,000 + 0 = 60,000

Therefore to find the velocity, well use the same formulae;

p = mv whereby;

p – momentum

m – mass

v – velocity

60,000 = (6000 + 4000) * v

v = 60,000 / 10,000

v = 6

= 6 m/s

This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.

What are the space limitations for human population growth?

Nonamiya [84]

If you’re talking about too many people I’m guessing the limitation factors would be lack of resources and that would include lack of food and space.
