Plants extract carbon dioxide from the atmosphere in order to manufacture sugars during photosynthesis. They deliver the sugars to microbes in the soil, which feed the root system of the plant. Animals absorb carbon when they eat plants, or when they eat other animals that have consumed plants.

saveliy_v [14]

Answer:

B. active transport

Explanation:

When a substance is to be transported from the area of its lower concentration to the area of its higher concentration, energy is consumed. The process is called active transport as it uses energy to move molecules against the concentration gradient. Membrane transport proteins such as pumps are involved in this type of transport. Therefore, the given bacterium needs to use the process of active transport to absorb the nutrients from the surroundings.

Carbohydrates must be consumed every 3 to 4 hours to prevent depletion of the glucose in our blood.

Varvara68 [4.7K]

Answer: option B) False

Explanation:

The body relies on SEVERAL sources for its energy or glucose supply.

Firstly, understand that Glucose could be supplied from the following:

Glycogenolysis (Glycogen break down induced by Glucagon)

Amino acids metabolism (once amine group is removed)

Fatty acid oxidation.

All of the pathways mentioned can directly or indirectly yeild GLUCOSE, thus making it UNNECESSARY for Carbohydrate meals to be consumed every 3 to 4 hours.

Therefore, the answer is False

lana [24]

Answer:

Yellow smooth - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1

Explanation:

Let the green color of the seed be depicted by "G" and the yellow color of the seed be depicted by "g"

Let the smooth the seed be depicted by "R" and wrinkled seed be depicted by "r"

F1 cross -

true breeding smooth green plant ( RRGG) and true breeding wrinkled yellow (rrgg)

F1 gamete will be RG, RG, rg, rg

F1 offspring will be RrGg , Thus all F1 offspring will be heterozygous smooth and yellow.

Thus, R is dominant over r and g is dominant over G

F2 Generation –

RrGg x RrGg

Gametes will be RG, Rg, rG, rg

RG Rg rG rg

RG RRGG RRGg RrGG RrGg

Rg RRGg RRgg RrGg Rrgg

rG RrGG RrGg rrGG rrGg

rg RrGg Rrgg rrGg rrgg

R is dominant over r and g is dominant over G

Genotypes are –

RRGG - 1 (Smooth Green)

RRGg-2 (Smooth yellow)

RrGG-2 (Smooth Green)

RrGg-4 (Smooth yellow)

RRgg- 1 (smooth yellow)

Rrgg – 2 (Smooth yellow)

rrGG – 1 (wrinkled Green)

rrGg – 2 (Wrinkled yellow)

rrgg – 1 (wrinkled yellow)

Yellow smooth - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1
