Answer:

Diffusion is the passage of molecules from a high-concentration region of the molecule to a lower-concentration area of the molecule.

Facilitated diffusion is the passage of a molecule with the assistance of a protein channel or carrier from a region of high concentration to an area of lower concentration.

BRAINLIEST!! ASAP Normal rain has a pH of about (?). 8.4 4.0 5.6 7.0

Aleksandr-060686 [28]

Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much more acidic. Typical acid rain has a pH value of 4.0.

The gene for petal color in a flower has incomplete dominance, so that individuals with two A1 alleles (A1A1) are black, individ

Verdich [7]

Answer:

The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.

Explanation:

Available data:

The gene for petal color in a flower has incomplete dominance

Two A1 alleles (A1A1) express black color

Two A2 alleles (A2A2) express white color

One of each allele (A1A2) express mottled color

In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:

Parental) A1A1 x A1A1

Gametes) A1 A1 A1 A1

Punnet Square) A1 A1

A1 A1A1 A1A1

F1 Phenotypes: 100% black flowers

F1 Genotype: 100% A1A1

There are 0% of probabilities of getting a mottled offspring.

IF most of the energy we use on earth comes from the sun –how does that energy (light and thermal) end up

____ [38]

Answer:

1: Chemical Energy

2: Kinetic Energy

3: Electrical Energy

4: Mechanical Energy

Explanation:

1: The energy held in food is called chemical energy. It is a form of potential energy held within chemical bonds between atoms.

2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.

3: The power for lights and stuff is Electrical Energy, ofc :]

4: The chemical energy in the food gets changed into the mechanical energy of moving muscles.

Hope this helps!! :D
