A) a common ancestor
Homologous structures are structures that are similar in related organisms. There is a basic pattern of bones which can be inherited from a common ancestor
Answer:
the electrical potential of a neuron or other excitable cell relative to its surroundings when not stimulated or involved in passage of an impulse.
Explanation:
Answer:
The correct answer would be - C. He is monitoring oxygen. The amount of gas released should be highest for the plant closest to the window and lowest for the plant farthest away from the window.
Explanation:
The release of the oxygen gas in the process of photosynthesis depends on the rate of photosynthesis which depends on various factors such as carbon dioxide, light, and water. In this experiment air (carbon dioxide), water is constant only factors that are changed is light, and an increase in the light energy increase the rate of photosynthesis, and a decrease in the intensity of light depend decreases the rate of photosynthesis.
Thus any change in the light would affect the release of the oxygen gas which is measured through this experiment and gas released should be lowest for the plant farthest away from the windowand highest for the plant closest to the window.
Answer:
Translation
Explanation:
The translation is the process during which the nucleotide sequence of the mRNA is read in the form of genetic codes. The nucleotide sequence of mRNA is complementary to the template DNA strand. According to the sequence of the nucleotides in the mRNA, the amino acids are added in a specific order to make the polypeptide chains. The process occurs on ribosomes. The ribosomes move along the mRNA to read its sequence and the tRNA brings are amino acids to be added to the polypeptide chains.
The correct answer is C. 50 %
A male is a carrier of a recessive somatic mutation it means the mutation can be expressed under homozygous condition, when both the alleles with somatic mutation. Thus, in case of a male carrier of a recessive somatic mutation marries to a normal female will produce 50 % their offspring with recessive somatic mutation so, they will be carrier and 50 % offspring are without this mutation.
