Answer:
<em>The rest of the cell cycle is called interphase, during which the cell carries out its normal functions.</em>
Explanation:
Interphase can be described as the normal living phase of the cell cycle. During this phase, the cell carries out its normal activities such as metabolism of nutrients, growth etc. During this phase, the cell also prepares itself for the process of cell division which could either be mitosis or meiosis. Interphase is usually referred to as the resting phase of the cell cycle but the cell does not rest in this phase as it carries out different metabolic activities.
Depending on the F1 generation (parent) phenotype we can determine whether or not it is homozygous or heterozygous. Also, check to if the F2 grey seeded plant is a mixture of Black and white or if grey is a dominant color. If it is a mixture, it would make it heterozygous. If not and Grey is domminant it would make it homozygous.
Answer:
a. The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
d. The photolysis of water releases H+ ions into the thylakoid space.
Explanation:
This question describes the first stage of photosynthesis, which is LIGHT-DEPENDENT REACTION. The light dependent reactions involve creating ATP (energy carrier) and NADPH (electron carrier) needed for the Calvin cycle (light independent stage) to occur.
The ATP is formed by pumping hydrogen ions (H+) into the thylakoid space/lumen, hence, creating a electrochemical gradient needed for ATP synthase to synthesize ATP. The buildup of H+ ions is caused by:
- The electrons that arise when light photons hit a chlorophyll molecule is used to provide energy for the H+ pump to transport more H+ ions into the thylakoid space.
- The photolysis of water results in the production of electrons (e-) and hydrogen ions (H+). These hydrogen ions are released into the thylakoid space.
wooah woah woah there ...take this in the dms ;))))
