The heart is in the diastole phase. In the diastole phase, the heart muscle relaxes and allows the chambers to fill with blood in preparation for the next cycle. In the systole phase, on the other hand, the heart muscles contract and this causes the ejection of blood into the aorta and pulmonary trunk.
Answer:
Cb>Cy>Co>Cr
Explanation:
First of al we need to do the Punnett square. As a result we get the genotypes:
CyCb
CyCr
CoCb
CoCr
Because there are no red frogs, red is the least dominant as it isn't expressed in any genotype.
Half of the progeny are blue and half of the possible genotypes contain the blue allele meaning that blue is expressed in all genotypes. This means that blue is the most dominant.
The only alleles left are yellow and orange. We can deduce that yellow is more dominant than orange because one of the parent frogs is yellow and contains the genes for yellow and orange.
As a result blue is the most dominant, yellow is the second most dominant, orange is the third most dominant and red is the least dominant.
Answer:
The correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.
Explanation:
Isotonic environment is an environment the amount of solute concentration is equal on both side of the semipermeable membrane or the cell. in such condition there would be no water movement towards particular direction or will take place and as there is no water movement so there would be no change in shape or size of the cell. The osmotic pressure in an isotonic environment would be same on both side of the membrane.
Thus, the correct answer is : The concentration of solute in the environment is equal to the concentration inside the cell.
The purpose is to produce gametes or sex cells that will help later during sexual reproduction
Summer means lots of out-of-doors time. Whether at beaches, barbeques, hanging out in the park or at the pool, most people catch more sun rays this season than other times of the year. In the process, some will get a suntan while others, unfortunately, will experience the painful redness, peeling and blistering that can occur with a bad sunburn.
