Because cellulose is required for the stem growth as cellulose is the main constituent of the cell wall and also provides toughness to the stem.

When less sunlight is in those months the photosynthesis also lowers, resulting in the use of stored energy i.e starch. Hence the starch level decreases.

Explanation:

Cellulose is required for the growth and toughness of the stem. During spring the budding and growth is fastest in plants hence supply of cellulose increases.

The starch is the energy stored in plants. It is a polymer of glucose. When sunlight decreases in some months the  rate of photosynthesis lowers down and plant starts using the stored form of energy  ie. starch, required for various physiological activities and growth of the plants. This is the reason the starch level decreases in plants sometimes.

Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget y
Vera_Pavlovna [14]
Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario.

Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds  

Solution:
A = 45 m/s – 15m/s / 6s
A = 5m/s^2

The genes R, E and D are independently assorting and control production of red pigment as follows (recessive alleles are not fun
Alona [7]

Answer:

1/8

Explanation:

An individual must have all three dominant alleles to be red, in homozygosis or heterozygosis (R_E_D_).

<u>The parental cross was:</u>

RREEDD x rreedd

F1: RrEeDd

<u>The test cross</u> is between the RrEeDd indiviudals and homozygous recessive rreedd.

The genes assort independently, so we can use Mendel's law of segregation to predict separately for each gene the proportion of the offspring that will have the dominant alleles.

<h3><u>Rr x rr</u></h3>

1/2 Rr

1/2 rr

<h3><u>Ee x ee</u></h3>

1/2 Ee

1/2 ee

<h3><u>Dd x dd</u></h3>

1/2 Dd

1/2 dd

Genes are independent, so the probability of having a R_E_D_ offpsring is calculated by multiplying the individual probabilities of having a dominant allele for each gene:

1/2 (Rr) × 1/2 (Ee) × 1/2 (Dd)= 1/8

Which fuel does the circulation of blood provide for cellular respiration and healing?
Lady_Fox [76]

Answer:

A. Oxygen

Explanation:

During cellular respiration the cell uses oxygen to break down sugar. When sugar breaks down it produces energy in which your body needs. Blood picks up oxygen and releses carbon dioxide into your lungs.

Hope this helps!!
