At impact, the force due to gravity is =

=

g
, where we see that a larger force corresponds to a larger mass. To rectify this with your intuition, as in a brick would hurt more if it landed on my head when dropped from a higher distance -- This is true (I don't recommend experiment), but the relevant quantity is
i

p

e
, which you can look up, or a more careful analysis of the acceleration of the brick when it lands on something, where we see that at contact, in a very short period of time, the velocity goes from →0
v

Where we see that the faster the brick slows down (

Step-by-step explanation: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.

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 Coriolis effect describes the pattern of deflection taken by objects not firmly connected to the ground as they travel long distances around Earth.
Explanation:
false because wind flows from areas of high pressure to areas of low pressure.
True because It takes less energy to change the temperature of land compared to water.
True because All wind is caused by the uneven heating of Earth's surface.
True because Wind is the horizontal motion of air. ... Therefore, the movement of air is called 'wind.

show that respiratory gaseous exchange in a rabbit occurs at the level of lungs
No single animal model can reproduce all of the human features of both acute and chronic lung diseases. However, the rabbit is a reliable model and clinically relevant facsimile of human disease. The similarities between rabbits and humans in terms of airway anatomy and responses to inflammatory mediators highlight the value of this species in the investigation of lung disease pathophysiology and in the development of therapeutic agents. The inflammatory responses shown by the rabbit model, especially in the case of asthma, are comparable with those that occur in humans. The allergic rabbit model has been used extensively in drug screening tests, and this model and humans appear to be sensitive to similar drugs. In addition, recent studies have shown that the rabbit serves as a good platform for cell delivery for the purpose of stem-cell-based therapy.

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.
GIVING BRAINLY! A car started accelerating and it gained speed at 2 m/s2. The car had a mass of 200 kilograms; calculate the average force the car was traveling at.
Answer: ____ Newtons
Answer:
100 Newtons
Explanation:
The car was traveling at an average force of 400 Newtons. This is the force that was being applied to the car to cause it to accelerate at a rate of 2 meters per second squared.
What is force?In physics, force is a measure of the interaction between two objects that can cause a change in the motion of one or both objects. Forces can be classified as either contact forces, which involve physical contact between two objects, or non-contact forces, which involve the interaction of objects without physical contact.
To calculate the average force that the car was traveling at, you can use the equation for average force:
average force = mass x acceleration
Plugging in the values given, you get:
average force = 200 kg x 2 m/s2 = 400 N

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.
