Compare the components that make up the windsurfer, his board, and his surroundings.
Sample Answer:
The windsurfer, his board, and the air and water around him are all made of matter. All matter is made up of very small particles called atoms, which cannot be divided.
The components that make up the windsurfer, his board, and his surroundings is matter.
Matter is defined as a substance made up of particles that has weight and can occupy space.
There are three main states of matter which include:
Solid: They have their particles vibrate in their fixed positions.Liquid: The particles are generally slightly further apart than in a solids; andGas: particles are widely spaced and tend to be only slightly attracted to each other.The windsurfer, his board, and his surroundings is made up of particles that are tightly packed together and vibrate in their fixed positions.
Therefore, the components that make up the windsurfer, his board, and his surroundings is matter.

Answer:
There are four fundamental forces which include the strongest force known as nuclear forces , a weaker force known as radiation ,electromagnetism and gravity.
Nuclear being the strongest helps in the formation of larger substances from smaller particles on the earth. Radiation helps in the transfer of light rays and other radiations between two or more bodies. Electromagnetism helps in the different charge transfers on the earth and gravity is the main force used to form the earth.

What usually happens when new evidence is discovered that is not already explained in an existing theory? Group of answer choices The existing theory is discarded, and a new theory is developed. Scientists choose sides and either support the existing theory or the new evidence. The theory is adapted to account for the new evidence.
Answer:
The best answer to the question would be - The theory is adapted to account for the new evidence.
Explanation:
If a piece of new scientific evidence is discovered for an already existing scientific theory that is already not explained in the theory it would be lead to the modification of the theory in order to make the theory so it can explain the newly find evidence.
If the theory can not be modified to fit the new scientific evidence the given theory is rejected ultimately. But more often theories are modified to explain the newer findings.
Thus, the best answer to the question would be - The theory is adapted to account for the new evidence.
What usually happens when new evidence is discovered that is not already explained in an existing theory is that more scientific evidence would be gathered about it.
Needless to say, a scientific theory may be modified and rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then requiredAccepted theories may however, be modified or overturned as new evidence Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more.

Pepsin and trypsin are two of the digestive enzymes that break down protein. A group of

The students found that pepsin functions best in an acid environment and trypsin functions best in a neutral environment. Based on their
observations, pepsin most likely alds in digestion in which part of the human body?
(5.9 points)
A. Pancreas
B. Intestines
C. Mouth
ID. Stomach
Answer:
D. Stomach
Explanation:
One of the most important digestive enzymes that aids digestion by breaking down of ingested food, most especially proteins is pepsin, which is usually referred to as "stomach enzyme".
Pepsin is found secreted in the stomach.
The pH of the stomach is usually low, between 1.5 to 2 (acidic). This acidic environment of the stomach actually favors this stomach enzyme, as it activated the pepsin to perform it's function.
Based on the observations made by the students, it can be concluded that pepsin aids digestion most in the stomach. It's pH requirement to function optimally matches with the pH of the environment of the stomach.

Which process results in two identical cells?
meiosis
replication
fertilization
mitosis
Answer:
d
Explanation:
The process that results in two identical cells is known as Mitosis. Thus, the correct option for this question is D.
What is Mitosis?Mitosis may be defined as a type of cell division through which two identical daughter cells are produced from a parental cell. These daughter cells are genetically identical to their parental cells and are mostly diploid in nature.
While the process of meiosis typically produces four daughter cells from a parental cell. These daughter cells are not genetically identical to their parental cells. These cells are haploid in nature.
The process of fertilization may be defined as when two distinctive gametes are fused together in order to produce a zygote. While replication is the duplication or synthesis of genetic material during the S-phase of Interphase.
Therefore, mitosis is the process that results in two identical cells. Thus, the correct option for this question is D.
