A hypotonic solution is a solution in which there is a lower concentration in solutes (ex. salt) dissolved in the solvent (ex. water). A hypertonic solution would be one in which there is a higher concentration of solutes in the solvent.
The
correct answer is no.
<span>The
development of retinoblastoma occurs as a consequence of mutation of genes RB1
or MYCN. Those mutations occur in the early stages of fetal development and affect
the way in which cells grow and develop within the body. The more common is the
defective RB1 gene that can be inherited from either parent. The expression of
the RB1 allele is autosomal dominant.</span>
Answer:
True
Explanation:
Lipoprotein contain some amount of lipid, protein, phospholipids and cholesterol. It carries fat(lipid) molecules in the blood to different parts of the cells and tissues. Fats acts as insulators and protect vital organs.
High level of lipoprotein in the blood causes arteriosclerosis which is the blocking and clogging of the arteries with fats. These fats makes flow of blood difficult in the blood and it eventually causes heart related diseases and death.
Diabetes can cause a variety of complications, including kidney problems, pain due to nerve damage, blindness, and coronary heart disease. Recent studies have shown that controlling blood sugar levels reduces the risk of developing diabetes complications considerably.
<span>Diabetes insipidus is caused by a deficiency of vasopressin, one of the antidiuretic hormones (ADH) secreted by the posterior lobe of the pituitary gland. </span>
Venus has a dense atmosphere that traps heat, raising the average surface temperature
Option C.
<h3><u>Explanation:</u></h3>
Venus is the planet in our solar system which is second most closest planet to the Sun. And it's well known for its surface temperature which is often exceeding a temperature of 480°C. Although the planet is lying far enough from sun, much farther than mercury, but the secret behind its highest surface temperature lies in its atmosphere.
Venus has an atmosphere which is 4 times denser than that of earth. And it's atmosphere is composed of 95.6% carbon dioxide. This is well known as a greenhouse gas. The atmosphere in venus is so thick that the surface of venus is never visible from earth. The dense atmosphere also consists of clouds of sulphuric acid and nitric acids.
