When kelp plants in coral reefs are exposed to sunlight, blue and red wavelengths of light are absorbed by the kelp. energy from green wavelengths is lost to the kelp. explain why this phenomenon does not violate the law of conservation of energy. a. kelp are a closed system, so energy is allowed to exit the system. b. the green wavelengths are reflected from the kelp, making them appear green. c. green wavelengths do not contain any energy, so its loss is acceptable. d. the law of conservation of energy does not apply to biological systems.

Option B, The green wavelengths are reflected from the kelp, making them appear green.

Explanation:

All green organisms (including plants) contains chlorophyll and thus they have a tendency to reflect green light which make them appear green. Green plant absorbs light from the blue and red light zones of visible light spectrum to carry out light reactions of photosynthesis and convert this light energy into  chemical energy (food).

When the green light is reflected, the amount of energy absorbed/used by plant is zero and hence there is no violation of Law of Conservation of Energy as no energy is being used in this case.

Therefore, the correct answer is option B The green wavelengths are reflected from the kelp, making them appear green.

good lesson

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
