There will be huge changes in an ecosystem
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
a. 25%
b.75%
c. 50%
d. Male cats have only one X chromosome in their DNA meaning that they should be unable to inherit different colours.
The synthesis of ATP is based on energy conversion, via conformational changes of the subunits.
A proton gradient on either side of the membrane into which the ATP synthases are inserted is necessary for their operation, which implies that the synthesis of ATP can not be done independently of a membrane. Within the mitochondrial inner membrane, it is the respiratory chain that provides the pH gradient by injecting protons into the intermembrane space during the transfer of electrons from one complex to another. At the level of the thylakoid membrane, it is the photosynthetic chain that injects protons into the lumen.
Answer: 1
Explanation: photosynthetic plants possess a double membrane organelle called chloroplast.this chloroplast contains chlorophyll chlorophyll are the reason plants
are green,they are green pigments which absorbs wavelengths of sunlight that is used in the production of glucose and other products through photosynthesis.this glucose is converted to starch ,which is the form it is stored
