d. growing and developing
The correct answer is option a. responding to the environment.
The sweating is the release of sweat from the sweat glands. The sweating releases the water molecules on the skin surface as a result of increased body temperature due to changes in atmospheric temperature. The water molecule from the skin evaporates causing a decrease in body temperature.
The panting increase in the heat loss by respiration, hence, it is also a respond to the increased atmospheric temperature. So, both the conditions are associated with the temperature increase outside the body, here change in temperature act as stimuli and body react according to change.
A: responding to the environment
The number of chromosomes in a somatic cell is 52 chromosomes as it undergo mitosis cell division.
A somatic cell is also called as vegetal cell. It can make up an organism’s body.
In a multicellular organism all the cells are somatic cells except gametes, stem cells and germs cells,
These cells are involve in growth and development of an organism, also help in repair and regeneration.
In our body, there are about 220 types of somatic cells.
Many cells are differentiated to perform various specific functions. some examples of somatic cell types are skin cells, nerve cell, muscle cell, blood cell.
Somatic cells have diploid set of chromosome and undergo mitosis and contain the same set of chromosomes. Hence, the somatic cell of an organism has 52 chromosome.

Secondary consumers must eat more often or consume more prey to obtain the same amount of energy as primary consumers.
Secondary consumers usually eat a smaller quantity of food than primary consumers because they obtain their energy from consuming other organisms rather than directly from photosynthesis.
This means that a significant amount of energy is lost as it is transferred up the food chain. For example, only around 10% of the energy stored in plants is transferred to herbivores, and only around 10% of that energy is transferred to carnivores.
This means that the higher up the food chain an organism is, the less energy is available to it.
Therefore, secondary consumers must eat more often or consume more prey to obtain the same amount of energy as primary consumers.

The correct option is some inherited genetic mutation can be good for the offspring.
Further Explanation:
The change in the sequences of deoxyribonucleic acid (DNA) is known as mutation. It can occur due to mistakes while making a copy of deoxyribonucleic acid (DNA) or due to some environmental factors. At the time of replication, the alteration can occur in the sequences of deoxyribonucleic acid which results in mutations.
Hereditary mutation is the mutation which leads to evolution as mutation occurs in germ cells. This type of mutation can pass from one generation to another. These mutations are inherited from parents.
Genetic mutations which are inherited from parents to offspring can be good as it leads to evolution. Genetic recombination or gene mutation can lead to genetic variation that is the difference in sequences of deoxyribonucleic acid between individuals of the same population.
