Explain how the recessive trait for coat colour is hidden in cats when two parents that are purebred for different fur colour ar
AleksAgata [21]
When two parents are purebred it means that they are homozygous for the characteristic that's being tested (in this case the fur colour). When they are crossed, the offspring will obligatory be heterozygous, an allele of each type from its parents. So, the trait that comes up will be the dominant trait, while the recessive trait will be hidden.

How can atmospheric nitrogen be converted to ammonium ions or nitrate ions?
Agata [3.3K]

Answer: When a plant or animal dies, or an animal voids waste products, the initial form of nitrogen is organic. Bacteria and fungi in the soil produce enzymes that convert the organic nitrogen back into inorganic ammonium ions (NH4 +). Ammonium is converted to nitrite ions (NO2 -) by soil bacteria like Nitrosomonas

Explain the processes of photosynthesis and cellular respiration
Anuta_ua [19.1K]

Explanation:

photosynthesis converts carbon dioxide and water into oxygen and glucose.glucose is used as food by the plant and oxygen as a by-product.

cellular respiration convert oxygen and glucose into water and carbon dioxide water carbon dioxide a byproduct and ATP is energy that is transformed from a process.

In which case would facilitated diffusion be needed?
melomori [17]

Answer:

The voltage-gated potassium channels associated with an action potential provide an example of what type of membrane transport?

A. Simple diffusion.

B.<u> Facilitated diffusion. </u>

C. Coupled transport.

D. Active transport.

You are studying the entry of a small molecule into red blood cells. You determine the rate of movement across the membrane under a variety of conditions and make the following observations:

i. The molecules can move across the membrane in either direction.

ii. The molecules always move down their concentration gradient.

iii. No energy source is required for the molecules to move across the membrane.

iv. As the difference in concentration across the membrane increases, the rate of transport reaches a maximum.

The mechanism used to get this molecule across the membrane is most likely:

A. simple diffusion.

<u>B. facilitated diffusion. </u>

C. active transport.

D. There is not enough information to determine a mechanism.

Carrier proteins - exist in two conformations, altered by high affinity binding of the transported molecule. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLE: GluT1 erythrocyte glucose transporter.

Channel proteins - primarily for ion transport. Form an aqueous pore through the lipid bilayer. May be gated. Moves material in either direction, down concentration gradient (facilitated diffusion). EXAMPLES: Voltage-gated sodium channel, erytrhocyte bicarbonate exchange protein.

This might be helpful... because I don't know anything about facilitated diffusion.
