The term describing the loss of electrons during metabolism is oxidation. In metabolic processes like cellular respiration, substrates are oxidized to release energy, playing a critical role in sustaining life.
The term that describes the loss of electrons that occurs during metabolism, the process by which your body breaks down and builds up molecules, is known as oxidation. Whenever a substrate is oxidized, it loses electrons. For example, in the process of cellular respiration, glucose is oxidized to carbon dioxide, and oxygen is reduced to water. The transferred electrons are carried by certain molecules to other parts of the cell to release energy used for metabolic functions. Therefore, metabolism and oxidation play crucial roles in our body to sustain life.

Ans.
The dominant allele can be defined as the allele, which can express itself in both heterozygous and homozygous conditions. On the other hand, recessive allele can only express itself in homozygous condition (when both the alleles for recessive traits are present. It means presence of one dominant allele can hide the expression of recessive allele.
In given experimental flower, red color is dominant over white color of flower. So, 'if a plant grower wants to produce red flowers only, he should choose both the parent plants having red flowers as they have at least one allele for red color that would transfer to their offspring.'
Lets understand this in a calculative way,
Let the parents genotype be RR and Rr
The offspring’s produced are – RR, Rr, Rr, RR, Thus all the offsprings are white as r is recessive, for producing a red flower the offspring must have “rr” genotype.
Now if parents have Rr and rr genotype , then the offspring would have Rr, rr, rr, Rr giving two white and two red flower. Of the second case may be where both the parent white flower are the carrier with genotype “Rr”
Thus in order to produce red flower the parents with following genotypes is necessary –
a) Both parents having Rr
b) One parents with rr and the other parent with Rr genotype
B. bone.
C. blood.
D. fat tissue.
Answer:
The correct answer is option A. "skin".
Explanation:
Hair and nails are derived from cells of the skin. The cells of the skin have keratin, a protein that creates a protective barrier against the environmental factors that could affect them. The hair and nails are modifications of skin cells, that have keratin but with additional features. The hair is made of 95% keratin and is formed of three components: medulla, cuticle and cortex. The nail cells are made from keratin as well, forming a horn-like structure that is replaced by skin cells constantly.
