Based on the gene chromosome theory, the law of independent assortment assumes that certain #genes are located on separate #chromosomes.

Certain insects resemble the twigs of trees on which they live. The most probable explanation for this resemblance is that #naturalselection has favored this trait.

A pyramid of energy can be used to illustrate the loss of usable energy at each feeding level in a food web. The #secondaryconsumer feeding level is where the the smallest amount of energy be found (as opposed to #producers and #primaryconsumers)

In order to survive, all organisms must carry out #enzyme controlled reactions

Two squirrel populations are prevented from mating only because they live on opposite sides of the Colorado River. This situation is an example of #geographicisolation.

The theory that birds and reptiles share common #ancestry is supported by the evidence that they both show structural similarities during their development

The term #evolution is best described as a process of change in a population through time.

As a result of #fertilization, the #diploid number of chromosomes is normally restored

A #zygote is an immediate result of in vitro #fertilization

An analysis of chromosomes may show the loss of a portion of a chromosome. This type of chromosomal change is known as a #deletion

The cloning of cells involves the process of mitotic cell division (#mitosis) #leregentsreview

Two cuttings taken from the same parent plant may differ in #phenotypes when they are grown in separate containers. This difference is most likely due to #environmentalfactors

Starch being formed by the chemical bonding of glucose molecules is an example of the life process known as #synthesis

African elephant tusks consist of high-quality ivory. In recent years, the elephant population in certain African wildlife preserves has decreased. This decrease is most likely due to #humanexploitation

Lions and hawks hunt and kill other living things before eating them. Based on this mode of nutrition, lions and hawks are classified as #predators
