T the correct answer.
olga2289 [7]

Answer:

False

Explanation:

Eukaryotes along with some prokaryotes also perform the process of photosynthesis. Photosynthesis needs chloroplast and it is also found in some of the prokaryotes.

Prokaryotes are primitive cells but they do have organelles like mitochondria and chloroplast.

Photosynthesis is the process by which glucose is made in the presence of sunlight out of which oxygen is released into the environment and carbon dioxide from the environment is used.

What causes there to be a H+ ion concentration gradient to build up inside the thylakoid space? Check all that apply. a. The ele
siniylev [52]

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.

Punnett Squares are used by geneticists to determine the likely genotypes of the offspring of two parents.
PilotLPTM [1.2K]
That's correct - it's a square where on one axis, the paternal allele (allele = one of the possible forms of the same gene), and on another the maternal allele is listed. Often, it's also indicated whether an allele is recessive or dominant.

Then, in the table that results, all the possible "combinations" of allele between the paternal and maternal party are created. If you count how often a certain combination appears, it indicates the likelihood of that combination.
See the picture (though it is directly from Wikipedia, please note). The likelihood of BB is 25%, of Bb is 50%, and of bb 25%.
