Explanation:
An object is subjected to an unbalanced force. What happens to the object
A- The object changes speed or direction.
B- The object continues moving at a constant speed.
C- Nothing changes.
Answer:
If an object has a net force acting on it, it will accelerate. The object will speed up, slow down or change direction. An unbalanced force (net force) acting on an object changes its speed and/or direction of motion. An unbalanced force is an unopposed force that causes a change in motion.
When an object experiences an imbalanced force, the item either alters its speed or its motion's direction.
Option A is the proper response, thus.
What is the second law of Newton?The resultant force exerted on an object is proportional to the rate of change of momentum, according to Newton's Second Law.
Force is equal to the product of an object's mass and acceleration because acceleration is the change in velocity expressed by either a change in speed or a change in direction.
One of two things occurs when an item encounters an imbalanced force: either the object alters its speed or its motion direction.
As a result, choice A is the right response.

A.Cells to repair damage in an organism
B.Cells for the growth of an organism
C.Cells that are gametes
D.Cells with identical genetic material to the parent cell

If a female fruit fly is heterozygous with the allele for white eyes being recessive and the red eyes being dominant on the X-chromosome. She is crossed with a hemizygous red eyed male, what would be the expected ratio of male and female phenotypes if they were bred together?
Answer:
100% red eyes because there is 50% AA and 50% Aa.
Explanation:
To find the expected ratio of male and female phenotypes if they were bred together, you need to make a punnett square/table.
Female: A a
"A" is white eyes, which is RARE. "a" is red eyes, which is COMMON.
Male: A A
"A" is red eyes, which is COMMON.
Multiply Aa x AA by a punnett square.
GUIDE:
1. AA is common and does not carry the recessive gene of being white-eyed. 2. aa is rare and carries the recessive gene of being white-eyed.
3. Aa is common as being red-eyed since being red-eyed is dominant, but carries the recessive gene of being white-eyed.

Answer:
D. 3H2O
Explanation:
An atom is the smallest unit of matter that has the characteristics of a chemical element. It consists of protons, neutrons, and electrons - small electrically charged particles.
They make up molecules - electrically neutral groups of two or more atoms connected by chemical bonds. Multiple molecules that consist of two or more different atoms make up a chemical compound.
The chemical compound that has nine atoms is 3H2O. Here, we have three molecules of water. Each molecule consists of three atoms - two hydrogen atoms and one oxygen atom. This means that three of these molecules have a total of nine atoms.
Why do the cells of the digestive system secrete proteolytic enzymes, such as pepsin, in their inactive forms
Answer:
In the initial stages of digestion of food, the stomach performs an essential role. Apart from doing churning and squeezing the food bolus, it also discharges an amalgamation of compounds, together called gastric juice. It comprises mucus, water, pepsin, HCl, and intrinsic factor. Of these five constituents, the principal enzyme that takes part in the digestion of protein is pepsin.
It dissociates proteins into amino acids and smaller peptides, which can easily get captivated within the small intestine. This pepsin is released in its sedentary form, or zymogen form called pepsinogen by the chief cells present within the gastric lining. It is released in its sedentary form by the stomach, by this the stomach inhibits the auto-digestion of defensive proteins in the digestive tract's lining.

Why do we perceive chlorophyll as being green?
a. Because it reflects green light.
b. Because it absorbs green light.
c. Because it absorbs yellow light.
d. Because it is green.
A .Because it reflects green light.
Explanation:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green
why the food pyramid is wider at the base and very narrow at the top
Answer:
The wider base stands for foods with little or no solid fats or added sugars. These should be selected more often. The narrower top area stands for foods containing more added sugars and solid fats. The more active you are, the more of these foods can fit into your diet.
Explanation:
A food pyramid can be defined as a graphical representation of a set of dietary guidelines and optimal number of servings from each of the basic food groups, which are to be eaten daily by an individual.
Basically, a food pyramid illustrate the principles of good nutrition and contribute towards a healthy balanced diet.
Foods and drinks that are highly rich in nutrients such as fruits and vegetables are found at the wider base (bottom) of the food pyramid while foods that are high in sugar, cholesterol, salt and fat are placed at the top.
In conclusion, the food pyramid is wider at the base because that is where all the very good and nutritious foods are illustrated while it is very narrow at the top because those are unhealthy foods and drinks for humans.

in an experiment what should be the relationship between the control group and experimental group?
Answer:
Ideally, the experimental and control groups are identical. As much as possible, the two groups should overlap in every characteristic.
Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.

How to illustrate the information?Important water qualities like adhesion and cohesion have an impact on how water behaves everywhere, from plant leaves to your own body. In Adhesion, W
water is drawn to other substances, while in cohesion, water is drawn to different types of water.
The force that draws molecules of the same substance together is called the cohesive force. The force that holds molecules of various substances together is known as the adhesive force.
Therefore, the properties of water that explain why it can be so destructive in heavy rains or floods is cohesion and adhesion.

Which of the following explains how photosynthesis takes place in a plant?
Answer:
D
Explanation:
Carbon dioxide enters through the stomata on the underside of the leaf.
Water is absorbed by the root hair cells and is transported to the leaf by the xylem vessels.
Sunlight provides the energy needed for photosynthesis to take place. In this process carbon dioxide and water are converted into oxygen (a waste product that is released back into the air) and glucose (the source of energy for the plant).
Oxygen is released through the stomata on the underside of the leaf; glucose is transported around the plant in the phloem vessels.
