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.

Which type of mutation is seen in a sperm cell but not in a skin cell?
katovenus [111]

Answer:

An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These alterations can (but do not always) cause cancer or other diseases.

Explanation:

when a skin stem cell harbors a cancer-driving mutation, it becomes more likely to generate two specialized skin cells when it divides. Over time, the mutated skin stem cell fails to renew itself and turns into cells that eventually slough off, allowing the skin to expel mutated cells as needed.

Errors in DNA copying during cell division and development can cause new mutations — called de novo mutations — at any time from the moment of conception. Mutations that occur in the germ line — the cells that develop into sperm or eggs — can be passed on to the next generation and, perhaps, cause disease in children.

suppose that individuals in a population of beetles differ in the extent of a dark pigment in their coloration. dark-colored bee
sesenic [268]

The coloration of the beetles most likely remains constant, despite differential predation, when it is strictly due to ENVIRONMENTAL factors. Phenotypic traits can be influenced by genes or the environment.

The expression of a given characteristic (i.e., a phenotypic trait) in an individual may be associated with genetic and environmental factors, as well as with the interaction between genetic and environmental factors.

Different types of environmental inputs (e.g., diet, temperature range, oxygen, humidity, light, etc) can influence a given phenotype.

A heritability value near zero (0) indicates that almost all of the phenotypic variability for a given trait is caused by environmental factors.
