Answer:
The Grants's research shows that variation within species increases the likelihood of the species' adapting to and surviving the environmental change.
Explanation:
The beaks of individual birds can change depending on what food is available.
Over time, individuals can evolve to better fit the environment by changing heritable traits.
Beak depth and length must affect survival and/or reproduction of birds.
Beak depth and length must be heritable.
Beak depth and length must show variation among individuals of a single species.
Answer:
Position Effect
Explanation:
Position effect is referred to the effect on gene expression when the gene is translocated from the location it is on a chromosome to another location.
As it relates to gene silencing and euchromatic gene repositioning, Position effect variegation best explains it.
Position effect variegation occurs when a gene in some cells is silenced as a result of rearrangement of chromosomes which translocate or reposition euchromatic genes close to vicinity of heterochomatin. It is this abnormal chromosomal juxtaposition that leads to the gene silencing in stochastic pattern.
Answer:
Option (D).
Explanation:
ATP (adenotriphosphate) molecules are considered as energy currency of the cells as molecules provide energy for various cellular functions.
The energy is stored in ATPs in two high-energy phosphate bonds, known as phosphoanhydride bonds. This stored energy is released in during hydrolysis of ATP, which involves removal of terminal phosphate groups bound the carbon backbone.
Thus, the correct answer is option (D).
The answer is (C), because, red blood cells or wbc regulate body temperature (Idr), wbc fight infections, and rbc transport nutrients
<span>DNA polymerase is the enzyme that connects new nucleotides and proofreads them into separate DNA strands.
This process is part of DNA replication. A cell's DNA is replicated before a cell divides. The two strands of a DNA molecule have complementary base pairs. Each strand in the pair consists of a nucleotide sequence which is able to provide the information to duplicate itself. Before the duplication occurs, the length of the DNA that is about to be copied must be unwound and the two strands must be separated. This is done by breaking the weak hydrogen bonds that link the pairs together. They must then be kept apart from each other to expose the bases so that the new nucleotide partners can bond to them. DNA polymerase is the enzyme that moves along the exposed DNA strand and joins the new nucleotides to manufacture a new DNA strand that is a duplicate of the original</span><span>
