True or false: male and female embryos look the same anatomically at five weeks of pregnancy.
Marizza181 [45]

The statement is true. The male and female embryos anatomically look same at five weeks of pregnancy.

In the 4th week of pregnancy the blastocysts gets implanted in the walls of uterus and develops into the placenta and then becomes an embryo. The embryo is considered starting from the point when the amniotic sac develops which is at the starting of the 5th week of pregnancy. By the 12th week of pregnancy the organs are developed such as arms and legs but the brain and spinal cord keeps developing throughout the pregnancy.

The second trimester begins at the 13th week of the pregnancy and by the 14th week the gender can be identified. So the male and female embryos are anatomically same at 5th week of the pregnancy.

S_A_V [24]

Answer:

The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.

Explanation:

In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.  

These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.
