Fermentation

Explanation:

To find the correct answer, we will review over the definition of each answer choice.

Photosystem I is A membrane in a plant that produces high levels energy from light

Based on the definition, we can conclude that photosystem 1 is not the correct answer.

ATP Synthase are molecules that create ATP

We know that this answer choice is also not correct.

Glycolysis is the process of breaking down glucose to create energy.

Based on the definition provided we know that this answer choice is also incorrect

Fermentation is the process of lactic acid being formed when there is not enough oxygen present for cellular respiration to take place.

Therefore, fermentation is the correct term we are looking for.

Which one of the following processes does not occur to excess neurotransmitters in the synapse
svlad2 [7]

This question is incomplete because the options are not given; here is the complete question:

Which one of the following processes does not occur to excess neurotransmitters in the synapse?

A. Break down or digested into inactive fragments.

B. Collection by scavenger vesicles left over from the neurotransmitter release.

C. Drifting away from the synapse via diffusion.

D. Reuptake within the pre-synaptic neuron.

The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.

Explanation:

The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.

Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.

elena-s [515]

Answer:

Temperate grasslands have <u>few trees.</u>

Explanation:

Althogh options are not given for this question, here is what I can speculate based on provided limited information.

Temperate grasslands have few trees and large shrubs (mostly absent). Here, <u>grasses are the main vegetation</u>. A major reason behind this is the <u>low average annual precipitation</u> which doesn't allow bigger plants to survive.

For the second part I can say that temperate grasslands have primary vegetation (grasses) whereas other biomes have higher plants as well.

The difference in heat distribution between the poles and the equator is due to Earth’s
kkurt [141]
The axis of the earth is tilted (ANSWER IS C). The equator is heated more than other areas because the sun's rays hit it directly.
As you move north or south of the equator, they fall slantingly or obliquely.
When summer is in the south and vice versa, the heat also changes with the earth's rotation.
The tropic of Capricorn and the tropic of Cancer alternately get direct sunlight.
Due to the uneven heating of the earth, wind and ocean currents are created, supporting life.
