Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean water.

Answer:

Evaporation

Explanation:

The process by which water changes its state from liquid to gaseous is known as evaporation.
Evaporation is the process that contributes to increased salinity of the ocean.
The process of evaporation removes water and hence as the water level decreases due to the rise of water vapor into the atmosphere, more salt is left behind in lesser water, thus increasing the salinity.

REY [17]

The patter of inheritance would support the hypothesis that the trait being studied is a recessive sex- linked trait found on the X chromosome "The trait is mostly expressed in males who have a maternal grandfather with the trait."

Explanation:

A pedigree chart is a illustration that displays the existence and arrival of phenotypes of a specific genetic factor or organism and its families from one group to the next, most usually individuals, show dogs, and race horses. A pedigree chart displays a family tree, and shows the members of the family who are affected by a genetic trait. This chart shows four generations of a family with four individuals who are affected by a form of colorblindness. Circles represent females and squares represent males.

Answer:

c. 1:4:6:4:1

Explanation:

The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.

Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.

Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. In the exposed example, the measurable trait is the dog´s friendliness. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.

In the exposed example, each dominant allele contributes with a higher level of friendliness.

aabb → 0 = Unfriendly/Loner (although not aggressive);
Aabb, aaBb → 1 = Somewhat friendly/shy;
AAbb, AaBb, aaBB → 2 = Friendly;
AABb, aABB → 3 = Very friendly;
AABB → 4 = Maximally friendly.

Cross: between two dihybrid friendly dogs

Parentals) AaBb x AaBb

Gametes) AB, Ab, aB, ab

AB, Ab, aB, ab

Punnett square) AB Ab aB ab

AB AABB AABb AaBB AaBb

Ab AABb AAbb AaBb Aabb

aB AaBB AaBb aaBB aaBb

ab AaBb Aabb aaBb aabb

F1) 1/16 AABB ⇒ 4 = Maximally friendly

4/16 AABb + AaBB ⇒ 3 = Very friendly

6/16 AAbb + AaBb + aaBB ⇒ 2 = Friendly

4/16 Aabb + aaBb ⇒ 1 = Somewhat friendly/shy

1/16 aabb ⇒ 0 = Unfriendly/Loner

The Phenotypic ratio is 1:4:6:4:1

Which of the following statements about the organization of the purine synthetic enzymes are true? The process involves multifun

Svet_ta [14]

Answer: All of the statements are true.

Explanation:

Purines are biologically synthesized as nucleotides and in particular as ribotides, that is, bases attached to ribose 5-phosphate. Adenine and guanine are both derived from the nucleotide inosine monophosphate (IMP), which is the first compound in the pathway to have a completely formed purine ring system.

Purine nucleotides can be synthesized in two distinct pathways. First, purines are synthesized de novo, starting with simple starting materials such as amino acids and bicarbonate. the purine bases are assembled already attached to the ribose ring. Alternatively, purine bases, released by the hydrolytic degradation of nucleic acids and nucleotides, can be salvaged and recycled. Purine salvage pathways are mostly noted for the energy that they save and the remarkable effects of their absence.

All statements are correct because the organization of purine synthetic enzymes involves multifunctional enzymes, reversible enzyme formations, through out the sequence there is maintenance of high local concentration and the ten steps requires only six enzymes.
