kondor19780726 [428]

Answer:

See the answer below

Explanation:

<em>Genotype is the genetic composition of organisms and a gene is made up of two alleles.</em>

a) Since the allele for black is B, <u>the genotype for black chickens would be BB. </u>

b) Since the allele for white is W, <u>the genotype for white chickens would be WW.</u>

d) Two erminette were crossed:

         BW    x    BW

i. <em>Probability of having black chick (BB) </em>= 1/4

ii. <em>Probability of having a white chick (WW)</em> = 1/4

iii. <em>Probability of having erminette chicken (BW)</em> = 1/2

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.
