Answer:
The correct answer will be option-Selective survival and reproduction is a requirement of evolution by natural selection.
Explanation:
Evolution is a slow process of change in the heritable features of species over a successive generation of time.
The process of evolution takes place during a long period of time only when the advantageous mutations are passed on to the generations and become established.
The mechanism of this process is natural selection which increases the reproductive rate as well as the survival rate of the species.
Thus, the selected option is the correct answer.
Answer:
The sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior, where temperature and pressure are extremely high. During most of the sun's life, energy comes from the fusion of hydrogen nuclei
Explanation:
B. semi-permeable
meaning: it is only partly permeable, not all substances can pass through the membrane.
Answer:
The correct answer would be C. With an input of energy, ADP combines with a phosphate group to become ATP.
Inorganic phosphorus and energy are added to adenosine diphosphate (ADP) in order to convert it to adenosine triphosphate (ATP).
This reaction is usually catalyze by the enzyme ATP synthase. It present in inner membrane of mitochondria of the cell as well as in the thyllakoid membrane in chloroplast.
ATP synthase uses the energy provided by chemiosmosis i.e. flow of protons down the gradient across the membrane through this enzyme. Proton gradient is formed either by photosynthesis or by cellular respiration.
ADP + inorganic phosphate (Pi) + energy → ATP + H₂O
ATP is used as the energy currency of the cell which breaks down to release inorganic phosphate group and energy which is used in various metabolic processes.
By placing the pots with detergent in the sun and the pots
without detergent in the shade, the student is not comparing the effects that
detergent has in the growing rate of the seeds under the same conditions;
besides, he does not have a control group. Therefore, he will not be able to
determine if the growing rate of the plants were affected by the detergent, the
lack of sunlight, or a combination of both factors.
