What type of tissue comprises the bulk of the myocardium
ycow [4]

Answer:

Cardiac muscle tissue

Explanation:

Myocardium or heart muscle is a special type of muscle (differ than striated and smooth) and it is the main tissue of the walls of the heart.

Heart muscle consists of individual heart muscle cells (cardiomyocytes) which are joined together by intercalated discs. It also contains  collagen fibres and other substances that form the extracellular matrix.

Heart muscle has a "special" mode of contraction: action potential triggers the release of calcium ions from the cell's internal store, the sarcoplasmic reticulum.

attashe74 [19]
<span>The vibrations are then sent to three tiny bones in the middle ear: the malleus, incus, and stapes. These bones then amplify the sound vibrations and send them to the cochlea, a snail-shaped structure in the inner ear. The vibrations then cause the fluid inside the cochlea to ripple along the basilar membrane. This ripple stimulates the hair cells that sit on top of the basilar membrane.</span>

"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".
