Answer:
It would be electrons.
Explanation:
b. Hypothesees are guesses; theories are correct answers.
c. Hypotheses usually are relatively narrow in scope; theories have broad explanatory power.
d. Theories are proved true; hypotheses are often contradicted by experimental results.
Answer: c. Hypotheses usually are relatively narrow in scope; theories have broad explanatory power.
Explanation:
In scientific decipline, the hypothesis is a tentative statement which is produced by the method of prediction and assumption based on direct observation of the natural phenomena or event. It can be tested by using the experimental methodology.
Theory is a explaination for the cause of natural event or phenomena. This is based on the evidences obtained after experimental trials. A hypothesis can be used for generation of theory. A theory is more explanatory approach because of the details and evidences than hypothesis. Hence, c is the correct option.
Answer:
Damage to the villi means less lactase released, so the body can't break down dairy.
Explanation:
If the small intestine is damaged, then that can mean that the villi are damaged. The villi usually release lactase, so this process will be compromised.
Less lactase released means that the body will have less of the enzyme required to break down lactose, the sugar present in dairy. Thus, individuals with celiac disease will struggle to digest dairy products
Answer:
They can be divided into simple carbohydrates, which include monosaccharides (e.g., glucose, fructose, galactose) and disaccharides (e.g., sucrose, lactose), and complex carbohydrates, which comprise starch and nonstarch polysaccharides (e.g., starch, glycogen, cellulose)
Explanation:

Lactose and cellulose are carbohydrates performing different functions: lactose is a disaccharide that provides energy and cellulose is a polysaccharide that maintains plant structure and serves as dietary fiber in human diet.
Lactose and cellulose are both types of carbohydrates, but they serve different functions. Lactose, also known as 'milk sugar', is a disaccharide made up of glucose and galactose. It is found in milk and dairy products. Humans ingest lactose and break it down with the enzyme lactase, providing energy for the body. People with lactose intolerance lack this enzyme.
Cellulose, on the other hand, is a polysaccharide and the main component of plant cell walls. It helps plants maintain their structure. Humans and many other animals cannot directly digest cellulose because they lack the necessary enzymes. However, some animals like cows and termites can digest cellulose with the help of microorganisms in their digestive system. Cellulose is an important part of human diet as dietary fiber.

Answer: seen below
Explanation:
Deoxyribonucleic acid (DNA) synthesis is the biological process by which DNA molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand. This strands are separated during replication (DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule). DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand.
Deoxyribonucleic acid (DNA) synthesis is continuous because extension of a single ribonucleic acid (RNA) primer occurs without interruption into the replication fork as it continues to open to the right as seen on the diagram below. On the upper lagging strand which is the discontinuous synthesis, here synthesis is discontinuous, since new RNA primers must be added as opening of the replication fork continues to expose new template.
b. Sequences of hydrophobic amino acids are the segments of the protein that span the membrane.
c. Sequences of hydrophobic amino acids are the segments of the protein that dissolve in the membrane.
d. Sequences of hydrophilic amino acids are the segments of the protein that dissolve in the membrane.
Sequences of hydrophobic amino acids are the segments of the protein that span the membrane. Thus option B is correct.
The Primary structure of proteins is the linear structure of amino acids formed by Covalent, peptide bonds to form primary structure of protein.
Secondary structure protein defined as the folded structures formed by hydrogen bonding among the amine and carboxyl group of the peptide chain and it finally form polypeptide then into protein.
These secondary structure present in two structure such as α – helix which form a polypeptide chain by hydrogen bonding and twisting into a right-handed screw with the -NH group of each amino acid residue.
The β – pleated sheet form of protein are stretched out ,laid side by side together by intermolecular hydrogen bonds.
