How does the body deal with amino acids?
Answer:
Amino acids are transported to the liver during digestion and most of the body's protein is synthesised here. If protein is in excess, amino acids can be converted into fat and stored in fat depots, or if required, made into glucose for energy by gluconeogenesis which has already been mentioned.

The weaker the stimulus received by the neuron,
A. the stronger the action potential
B. the weaker the action potential
C. the stronger the local potential
D. the weaker the local potential
The weaker the stimulus received by the neuron,the weaker the action potential. That is option B.
What is action potential?Action potential is defined as the signals generated by neurons which is an electrical activity caused by a depolarising current in the neuron.
Practically, the greater the strength of a stimulus, the greater the number of action potentials generated in a nerve cell.

What are made from the flower of a plant
Answer:
Seeds
Explanation:
Flowers contain sporangia and are the site where gametophytes develop. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. After fertilization, the ovary of the flower develops into fruit containing seeds.
During a practical class of microscope handling a student did not see enough light what should the student check
Answer:
The student should try moving the slide and turn the coarse knob to get more focus. Once the sudent has got more light, use the fine focus knob to see better.
If a student is not getting sufficient light while using a microscope, they should first check the microscope's light source and its intensity. Then, they should inspect the condenser's position and aperture, adjusting them if necessary. Lastly, they should ensure proper specimen preparation and slide placement for optimal illumination.
When using a microscope, a student who experiences poor lighting should start by looking at the microscope's light source. Checking and adjusting the light intensity as necessary. The condenser's location and aperture should then be examined. Light focussing and distribution can be considerably enhanced by adjusting the condenser's height and aperture.
The student should also check that the specimen was properly prepped and placed on the slide. Poor illumination might also result from improper specimen placement or inadequate specimen preparation. The student can improve the light for efficient microscopy by methodically addressing these aspects.

What is learning?
The adaptive behavior skill evaluation in respect to pupils is the behavior that a student should persist in accordance with their age and surroundings. These abilities are regarded as the fundamental daily competencies that kids must possess in order to function properly.
These abilities assess pupils' performance based on their participation in regular activities. These abilities test a student's ability to interact and act appropriately even in the absence of other people.
Therefore, PIRLS (Progress in International Reading Literacy Study) is used to quantify the power to hold learning to everyday issues. The correct option is a.

A cell has a mutation that disrupts the insulin binding site of the insulin receptor. Based on the information in Figure 2, predict the effect of this mutation on the activity of GSK3. Justify your prediction.
Answer:
See Explanation
Explanation
If insulin cannot bind to the insulin receptor, then GSK3 will not be inhibited, nor will it be able to inhibit glycogen synthase as the activity of kinases such as PKB and GSK3 are dependent on the signal sent out as the response of binding insulin to the receptor. No binding leads to no signal which leads to no activity.

3. In my opinion, the use of archetypes in a story like "The Apple Tree" isn't lazy or unimaginative. This is because of various reasons, mainly being that it is extremely hard to come up with anything completely original. Chances are that anything you think of has already been thought of, made, or in the process of being made. I believe as long as something isn't completely copying something else, then it is okay for it to exist. For example, "The Apple Tree" and the story of Adam and Eve follow the same plot archetype and are similar in many ways. But the two stories talk about two very different concepts. I believe it is okay to take inspiration from something else because that is how evolution works, and without evolution, humans wouldn't be where they are today.
