106.5N
Explanation:
Given parameters:
Mass of cart = 75kg
Velocity = 4.4m/s
time taken = 3.1s
Unknown:
Force = ?
Solution:
To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".
F = m x a
F = force on body
m = mass of body
a = acceleration of the body
But we know that acceleration is the change in velocity with time of a body;
a = 
F = m x 
V is the velocity
t is the time taken
F = 
= 106.5N

That's what is called competitive enzymatic regulation. If there are more of that substance than the enzyme substrate, then most of the enzyme, if not all depending on the substance's concentration, will be inhibited on its action. If there are more substrate then the competitive substance, the expected reaction for that enzyme will happen at an expected rate. If the ratio substrate:substance is 1:1 then the reaction enzyme-substrate is very slowed down.
Answer to Question 1:
True
Explanation
As indicated in the passage, fruiting bodies of fungi differ structurally. However, different species can appear to be similar and often misleading thus creating the risk of food poisoning.
Question 2:
Many experiments require student-supplied items, such as _____.
1. Chicken
2. Fresh flowers
3. Distilled water
4. All of the Above.
Answer to Question 2:
The correct answer is 3.
Explanation
Water comes in varying degrees of purity. When water that contains other substrates or impurities is used for an experiment, it distorts the results and creates errors. So the scientist's ability to determine the root of a problem becomes enervated.
Using distilled water impurities removes the possibility of such an error. Distilled water is also used for cleaning laboratory equipment.

The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.
<h3><u>Explanation</u>:</h3>
Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.
This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.
