The R locus determines flower color in a new plant species. Plants that are genotype RR have red flowers, and plants that are rr
tatiyna

Answer:

The correct answer will be- Non-Mendelian inheritance (incomplete dominance)

Explanation:

Incomplete dominance is a type of inheritance pattern observed in nature in which none of the two alleles completely show their effect and produces a third type of phenotype which is different from the phenotype of both the parents.

In the given question, since the cross of red flower and white flower produces a third type of flower color known as pink during F₁ generation is the result of the incomplete effect of both the alleles.

Cross

RR (red) x rr (white) = Rr (pink)

Thus, incomplete dominance is the correct answer.

IrinaVladis [17]

Answer: Option C) blocks oxygen transport in human blood

Explanation:

Carbon monoxide (CO) is one of the oxides of carbon formed when fuel is incompletely burned. It can be generated from exhaust pipe of vehicles, electric generators.

When inhaled CO attaches to the hemoglobin portion of the red blood cells, forming a bound complex called CARBOXY-HEMOGLOBIN, that is unable to transport oxygen to the body tissues.

Thus, by this mechanism Carbon monoxide blocks oxygen transport in human blood

What is the length of a triglycerides? How are glycerol and fatty acids “connected” to make a triglyceride?
Ostrovityanka [42]
Every fatty acids has a long hydrocarbon chain (with even amounts of carbons, usually 16 or 18) and a carboxyl group.

glycerol is a 3-carbon molecule with 3 -OH groups.

fatty accids and glycerol can be connected by single or double bonds, depending on if the fatty acid is saturated or unsaturated.

when a lipid forms, the -COOH functional groups of 3 fatty acids react with -OH groups of glycerol.

this leaves 16, 18, or 20 carbons, making a triglyceride 16, 18, or 20 carbons long.

hope this helps!
