Answer:
a. autotriploid of species A: 63 chromosomes
b. autotetraploid of species B: 96 chromosomes
c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes
Explanation:
<u>For a.</u>
this species will have 3 haploid sets of chromosomes ('tri' means 3)
one haploid set = 21
21 × 3 = 63 chromosomes
<u>For b.</u>
this species will have 4 haploid sets of chromosomes ('tetra' means 4)
one haploid set = 24
24 × 4 = 96 chromosomes
<u>For c.</u>
there are two ways to do this:
1) two sets of chromosomes from species A and one from species B
42 + 24 = 66 chromosomes
2) one set of chromosomes from species A and two from species B
21 + 48 = 69 chromosomes
Hope that answers the question, have a great day!
During a myocardial infarction, proteins that are normally inside the cells leak into the plasma, due to loss of plasma membrane integrity.
<h3>Cardiac disorders and it's effects:</h3>
There are different types of cardiac or heart disorders that occurs due to different etiological origins.
Example of a cardiac disorder is the myocardial infarction.
Myocardial infarction is defined as the blockage of blood flow to the heart by the presence of blood clot.
This hinders the delivery of oxygen carried by the blood to tissue cells leading to apoptosis (which is a programmed cell death).
This will cause the plasma membrane of cells to lose its integrity leading to leaking of proteins into the plasma.

Answer:
_________
Explanation:
Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
