Answer:

Bronchospasm

Explanation:

Bronchospasm is known to be a condition that results from the contraction of the muscles that is found in the wall of the bronchioles which result into obstruction and narrowing of the respiratory airway. Thus, substance released from basophils or mast cell under the control of anaphylatoxin usually causes Bronchospasm. Furthermore, Bronchospasm is commonly caused by asthma and can also be caused by allergic reactions, respiratory infection, and chronic lung diseases.

"Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely
lyudmila [28]

Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"

A) complete dominance

B) incomplete dominance

C) codominance

D) epistasis

E) incomplete penetrance

Answer:

B) incomplete dominance

Explanation:

Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.

For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".

<span>A. Roots    B. Stem    C. Xylem    D. Phloem

The pathway that the viruses would most likely follow on first entering the plant is D. PHLOEM.

The phloem, whose purpose is to transport food from the leaves to the plant, is used as the pathway to spread the virus throughout the plant. The manifestation of aphid transmitted virus is the yellowing, mottling, or curling of leaves and the stunted growth of the plant.
