Answer: Option (A) is the correct answer.
Explanation:
In a gravitational field, energy possessed by an object is known as gravitational potential energy.
Whereas kinetic energy is the energy possessed by an object due to its motion is known as kinetic energy.
Therefore, out of the given options description of water flowing downhill and spinning turbines is an example of gravitational potential energy transforming into kinetic energy.
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
Answer: is to work with genes in complex and often unknown ways in the development of these traits.
Explanation:
The development as well as the expression of the traits in a living being depends upon both genes and the environmental factors. The heredity traits as well as the environmental factors both are responsible for the expression of the traits in the living beings.
Relatively how genes express their traits is dependent upon in the environment they are present. Sometimes, the environment restricts the expression of genes. The effects of the environment depends upon the genes with which they interact with.
For example, the people may vary in height. The environmental factors like proper diet, lack of exercise may suppress the trait of tallness in some living beings. Thus the expression of the gene becomes unknown due to environmental conditions.
Answer:
Option (d).
Explanation:
Telomere may be defined as the repetitive DNA sequence present at the ends of the chromosomes. Telomeres consists of the nucleotide sequence rich in G and consists of vertebrate sequence AGGGTT.
The mutation in telomerase enzyme can cause the excessive replication of the telomeres. These leads to the excessive cellular proliferation and makes the cell immortal. This extensive growth of telomere is one of the maine reason of the cancer development.
Thus, the correct answer is option (d).
