Answer:
D (Genotype)
Explanation:
A genotype is the genetic make up of an organism i.e. what the genetic material
of an organism constitutes. Genotype describes the set of genes contained in an organism's genome. According to Mendel, an organism receives two forms of genes called ALLELE for a trait, one from each parent. The genotype of a specific gene coding for a trait is represented by each pair of allele for that trait.
Although the genotype of an organism is outwardly invisible i.e. cannot be seen, but it determines the phenotype of that organism i.e. the outward appearance. For example, if a plant receives T and T alleles coding for tallness, from each parent. The genotype of that plant for the specific height trait will be (TT). Hence, the TT genotype although invisible but controls the tallness of the plant.
Answer:
4) Replacement of GDP by GTP on the Ga after interaction with an activated GPCR.
5) Conformational change in the Ga subunit causing a decreased affinity for the Gb g subunit.
2) Dissociation of Ga from the G protein complex.
6) Ga-subunit with its attached GTP activates an effector like adenylyl cyclase.
3) Production of a second messenger, like cAMP.
1) Activation of one or more cellular signaling proteins.
Explanation:
It is a signaling cascade initiated by G proteins. These G proteins function as molecular switches capable of activating signaling pathways in the presence of guanosine triphosphate (GTP), which is hydrolyzed in order to produce energy
The right answer is freed the hands for other uses.
bipedality is also more economic than tetrapedality, but it is not as fast and does not offer a high jumping skills.
The standing position has an advantage in reproduction because it has become attractive to females and more or less successful imitation in males, depending on their abilities, but bipedalism is a disadvantage in childbirth.
A group of dolphins is called a pod. This is the same for whales.
