Answer:
A)
Explanation:
neurotransmitters have excitatory effects on the neuron. This means they increase the possibility of producing an action potential in the receiving neuron
When excitatory neurotransmitters stimulate a single neuron, the neuron more likely to produce an action potential. Thus option A is correct.
what is neurotransmitter ?
Neurotransmitters are nothing but the endogenous chemicals released by axon terminals of neurons into the synaptic junctions and its main role is to control the function of the nerve cell.
Some Imbalance of neurotransmitters such as serotonin, norepinephrine and dopamine mainly result in depression.When the level of glutamate neurotransmitter leads to changes in the level of Dopamine cause transition into psychosis.
Different neuro transmitters like enkephalin and serotonin are involved in analgesia system like pain suppression, When Serotonin are released causes local cord neurons and both presynaptic and postsynaptic inhibition of pain fibres.
neurotransmitters have excitatory and inhibitory effects on the neuron which means they increase or decrease the possibility of producing an action potential in the receiving neuron

Fertilization in angiosperms requires a pollen grain to rapidly grow a pollen tube from the stigma to the embryo sac. From there,
how does the pollen tube enter the embryo sac to reach the egg?
The pollen tube enters the embryo sac at the micropyle, which is a small pore at the bottom of the sac.
What is plant fertilization?
After pollination and germination, sexual reproduction in plants takes place during fertilisation. The joining of the male gametes (pollen) and the female gametes (ovum) to create a diploid zygote is known as fertilisation. After the carpel has been pollinated, a physical-chemical process takes place. The entire sequence of this process occurs in the zygote before it matures into a seed. Flowers are the reproductive structures of angiosperms, so they play a significant role in the fertilisation process. In plants, the process of fertilisation takes place when haploid gametes combine to form a diploid zygote. Male gametes are transferred into female reproductive organs by pollinators during fertilization, and the result is the development of the embryo in a seed.
Hence, the micropyle is essential for the entry of the pollen tube into the embryo sac.

Which process would change metamorphic rock to igneous rock?
O melting followed by cooling
O pressure followed by weathering
O erosion followed by compaction
O cooling followed by cementation
Answer:
The correct answer is Option A.
Explanation:
A metamorphic rock becomes an igneous rock through the process of solidification. In this process, the atoms in the rock rearrange themselves until they form a solid structure. The atoms in a liquid or gas are in constant motion, but when they are solidified, they form a fixed, crystalline structure.

After an experiment, Monica creates a graph that chose a direct linear relationship between the size of a fish and the amount of oxygen the fish uses. Describe this trend, in terms of the amount of oxygen that a fish would use, as it grows from being very small to very large.
Based o Monica's linear graph, the growth of the fish means more demand for oxygen.
How does an increase in body size affect the demand for nutrients by living organisms?An increase in body size increases the demand for nutrients in living organisms.
This is because an increase in the size of organisms or growth results in an increase in the number of cells, and the needs of each cell also increase.
Thus, for the direct linear relationship between the size of a fish and the amount of oxygen the fish uses, the demand for oxygen for the fish will increase with the increase in the size of the fish.

C. It will remain alive underground and
for many years will grow, flower, and

Explain why the response of the eye to light is faster than the response of
the seedling to light.
Answer:
Eye is controlled by brain which is quicker than the seedling. When the light enters the eye, the optic nerves detect the light and sends the message to the brain quickly. This speed of response is not in plants. Therefore, the response of the eye to light is faster than the response to seedling to light.

A doctor uses a circular tool to remove a small core of skin, including deeper layers (epidermis, dermis and superficial fat). Excisional biopsy. A doctor uses a small knife (scalpel) to remove an entire lump or an area of abnormal skin, including a portion of normal skin down to or through the fatty layer of skin. The mole is removed in a procedure under local anaesthetic. You will be given a local anaesthetic by injection at the place on your body where the biopsy will be taken from. The local anaesthetic may sting a little when it is injected, however, the skin will then go numb and the operation should be pain-free.

In neuroscience terms, neurons have two types of impulses
Photosynthesis is the process by which autotrophs produce their own food. It is an anabolic reaction in which energy is stored (endergonic). Consequently, Cellular Respiration is the opposite of Photosynthesis. In Cellular Respiration, heterotrophs consume food to produce energy. It is a catabolic reaction in which energy is released (exergonic). Both metabolic processes are essential to sustain life. Describe the similarities and differences between the biochemical pathways of Aerobic Respiration and Photosynthesis in eukaryotic cells. Include in your discussion the major reactions, the end products, and energy transfers.
The similarities between aerobic respiration and photosynthesis are that they are both metabolic reactions and ATP is used at some point in each of the reactions.
The difference between aerobic respiration and photosynthesis is that:
aerobic respiration produces carbon dioxide and water as an end-product whereas photosynthesis produces oxygen and glucose as an end-product. aerobic respiration uses oxygen and glucose as starting materials whereas photosynthesis uses carbon dioxide and water as starting materials ATP is used by photosynthesis, whereas ATP is produced in cellular respirationThe equations of photosynthesis and celli=ular respiration are given below:

Gene duplication is a new gene formation phenomenon that fits the ortholog type of homology in evolution.
What is homology in evolution?The expression homology in evolution makes reference to the emergence of similarities between two or more sequences due to a common origin, which may occur as a consequence of gene duplication and subsequent divergence of ortholog sequences in order to play different roles as genetic material in the cell of an organism.
Therefore, with this data, we can see that homology in evolution is caused by similarities due to a common ancestor and it may be due to gene duplication.
