They are both isotopes of the same element because they have the same number of protons but a different number of neutrons.

Incomplete dominance

Westkost [7]

Answer:

D

Explanation:

Incomplete dominance is a phenomenon in genetic inheritance that occurs when the two alleles of a gene seem equally effective in their influence on a trait. It is a form of Intermediate dominance in which one allele for a specific trait does not completely mask the expression of its paired allele, as opposed to Mendel's law of dominance. Incomplete dominance results in a third phenotype different from the parent phenotypes but a combination of both.

In incomplete dominance, the intermediate/resulting phenotype is the heterozygous genotype.

Gregor Mendel discovered this concept of incomplete dominance in the flower of four o'clock plants when he crossed a purebred (homozygous) red-flowered (RR) with a purebred (homozygous) white-flowered plant (rr) to get F1 offsprings that are all heterozygous but have pink flowers (Rr). He later self-fertilized the F1 offsprings to produce a phenotypic ratio of 1:2:1 consisting of 1 red, 2 pinks, 1 white flower respectively.

This showed that the allele for red flower (R) is incompletely dominant over the allele for white flower (r), hence, producing an offspring with a different trait that arose from the blending of the two phenotypes.

Incomplete dominance is similar but different from co-dominance in the sense that, in co-dominance, both alleles/traits are expressed completely in the new phenotype produced while in incomplete dominance, the new phenotype is just a blending of the two phenotypes.

What happens to the carbon dioxide which collected in human tissues?

avanturin [10]

Carbon dioxide in the tissues is produced as the result of oxidation of glucose...

Most arthropods and some mollusks and tunicates have _____ circulatory systems, which means fluid transporting nutrients and oxy

Gelneren [198K]

Arthropoda and molluscs have open circulatory systems - meaning haemolymph (Their equivalent to blood) directly bathes the tissue, and isn't enclosed in blood vessels, as seen in a closed blood system, as in humans for example.

The coefficient of viscosity of blood is directly proportional to the frequency of interactions of erythrocytes with the vessel

Fed [463]

The coefficient viscosity is the resistance for blood to flow. There is a direct relationship between vessels diametre and viscosity. In the attached files it is the graph that best describes this relationship.

<h3>What is blood viscosity?</h3>

Viscosity is the property of fluids to resist the tangential displacement of molecule layers.

Blood viscosity refers to the resistance for blood to flow. Blood viscosity depends on the blood density and the vessel diameter.

Viscosity increases when the number of blood cells increases and when more cells get in contact with vessels walls.

The more viscose is in the blood, the greater resistance there is to move it, and the more blood pressure it requires to flow through vessels.

Viscosity decreases when blood velocity increases.

According to this framework and to the problem statement, we could assume that

smaller vessels ⇒ faster flow ⇒ less wall resistance → less vistosity

bigger vessels ⇒ slower flow ⇒ more wall resistance → more viscosity

In smaller vessels, blood flow is greater and more cells move in the center, leading to fewer cells interacting with walls. There is higher pressure and less resistance for blood to flow.

In bigger vessels, blood flow is slower, and more cells are interacting with each other and with the vessel walls. There is lower pressure and more resistance for blood to flow.

Since <em>the </em><em>coefficient of viscosity</em><em> is directly proportional to the frequency of interactions</em><em> </em><em>of </em><em>erythrocytes</em><em> with the </em><em>vessel walls, </em>we can assume that blood flowing through bigger vessels express a higher coefficient of viscosity than blood flowing through smaller vessels.

In the attached files you will find an image representing the relationship between the coefficient of viscosity and vessel diameter.

You should compare this image with your images and choose the correct one.
