Answer:
Mutations are random, but natural selection is not random. Different mutations can cause the same phenotype. Evolution repeats itself in different environments.
Explanation:
Introduced by Charles Darwin, natural selection is the idea that a species adapts to its environment through changes in its genetics. Natural selection is not random, though the genetic changes (or mutations) that are filtered by natural selection do come about randomly.

At an incineration facility, 90% of the garbage's volume is lost. The last 10% is in the form of Ash.
What do you mean by Incineration facility?An Incineration facility may be defined as a facility that tolerates municipal solid wastes and disposes of them through the method of combustion.
When this facility tolerates the wastes, approximately 80 to 90% of its volume gets lost. The remaining is left in the form of ash. It is formed just bottom of the incinerator unit.
Therefore, it is mentioned above.

5.) Morgan buys a male python from a snake dealer who tells him that the snake carries the albino allele. Morgan mates the snake with an albino female, and ten normally pigmented offspring are produced with zero albino offspring. Morgan rushes back to the snake dealer and demands his money back stating that the male he bought is not heterozygous for the albino allele because all of its offspring had normal pigmentation. Is Morgan’s position supported by genetic theory? Why?
From the illustration, Morgan's claim could be valid and his position is supported by genetic theory.
Dominant/recessive allelesIt can be inferred from the claim of the snake dealer that albinism in male python is a recessive trait. If this claim is true, let us assume that the albino allele is represented by b and the alternate form is B.
The genotype of the snake Morgan bought will be Bb as claimed by the dealer.
Morgan mated Bb snake with an albino snake which would be bb.
Bb x bb
Bb Bb bb bb
Thus, the mating should have produced albino to non-albino snakes in the ratio 1:1.

what molecules do plants take in for their energy needs
Answer:
Photosynthesis is the process by which plants produce food. Plants use their leaves to trap light energy during photosynthesis. Plants use the sun's energy to convert water and carbon dioxide into glucose, a sugar. Plants use glucose for energy and to manufacture cellulose and starch, among other things.
Another explanation:
Also, photosynthesis is a chemical reaction that takes place in a plant's leaves and requires both chlorophyll and light energy. Chlorophyll in leaves aids in the conversion of carbon dioxide and water into oxygen and glucose during photosynthesis. Glucose serves as a critical source of nutrition for the plant.

Human activities that leads to clearing of trees include the following:
agricultural expansion, cattle breeding, timber extraction, mining, oil extraction, dam construction and infrastructure development.One of the negative effects of deforestation on food web is the reduction in food availablity. This is so because of the loss of biodiversity that are source of food to man.
