A & E

This is a cellular respiration question, related to biology.

Some processes in our bodies require the use oxygen, others do not.

In this case, the conversion of pyruvic acid to acetyl co-enzyme A and the production of water in the electron transport chain do require oxygen.

If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. Water in the ETC is formed in the process when NADH and FADH2 are converted to molecular oxygen due to the electron transporters. The protons are then pumped and oxygen is reduced to form H2O.

4. Use your knowledge about the relationship between nutrients and photosynthesis to explain the trends you observed in the data
Step2247 [10]

Answer:

The trends go up in the presence of nutrients.

Explanation:

There is a great relationship between nutrients and photosynthesis because photosynthesis can't occur without without the availability of nutrients. Plants uses carbon from the atmosphere which is a nutrient whereas other nutrients such as nitrogen, phosphorus, potassium etc from the soil with the help of the roots. If these nutrients are available in the surrounding, the plant produced more food during photosynthesis because these nutrients are the food of plants so the trends go up in the presence of nutrients and lowers down in the absence or lower concentration of nutrients.

plant and animal development share a number of features, but differ in major ways as well. which of the following best summarize
Simora [160]
Both plant and animal development is seeded in the perspective that a cell divides itself to form a tissue and tissues grouped will become an organ and the organism itself. The cell hierarchial model is followed in the development in both of these diverse however seemingly similar organisms.

Ape species began to dwindle during the Miocene, leaving only a few remaining: a situation that exists up to the present. It is
fiasKO [112]

The change in weather pattern caused forest to become sparse and hot weather caused the reduction of apes as they had less food and difficulty in surviving the climate.

Explanation:

In Miocene epoch volcanic mountain chains were created in Central Africa which abruptly changed the local weather.

The sea-level got drop due to global cooling of that time.

This resulted in continental drift making land connection of Africa with Eurasia.

The primates started migrating through this route.

The African forest become dry causing selective pressures in primates.

The cooler climate in Eurasia caused extinction and migration of primates to Africa in late Miocene epoch.

The hot and humid climate and less woodland caused a reduction in number of apes which were replaced by modern world monkeys.

What is the name of the photosynthetic process in which light energy is converted into chemical energy in ATP and NADPH
abruzzese [7]
Thus, light energy is initially converted to chemical energy in the form of two compounds: NADPH, a source of energized electrons ( "reducing power"); and ATP, the versatile energy currency o that the light reactions produce no sugar; that happens in the second stage of photosynthesis, the Calvin cycle.
