The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. As the Earth travels around the Sun, the hemisphere that is tilted towards or away from the Sun changes.
Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
Answer:
SER, they are capable of synthesizing testosterone of Adrenocortical cells.
Explanation:
Adrenal smooth microsomal cells are enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.
Answer:
hybrid
Explanation:
A two-gened cell is not even a thing. The answer is a hybrid animal. Hope it helps!
If there is too much of glycogen and fat stored in a cell can be toxic. It damages the organs and leads to diseases.
Explanation:
Glycogen is stored in the liver or muscle tissue, the diseases affect functioning of the liver, kidney and the muscles. These diseases are mainly caused by genetic enzyme that is inherited from both parents.
The glycogen storage diseases are Von Gierke disease, Pompe's disease, Cori's disease, Hers' disease. The symptoms of this glycogen storage diseases are Low blood sugar, An enlarged liver, A swollen belly, weak muscles.
It is a metabolic disorder caused by enzyme deficiencies affecting glycogen synthesis in muscles.
