Answer: unfavourable ph condition for the pepsin
Explanation: during digestion, enzymes are needed to aid the process.digestive enzymes are biological catalyst that breakdown large food particles into digestible form .
As biological catalyst, enzymes require an optimum temperature and pH condition.outside this temperature or pH,the enzyme is denatured.
In the stomach, hydrochloric acid is required to convert pepsinogen into it's active form,pepsin.the acid also creates an optimum low pH that pepsin needs to function.
As the food moves to the small intestine,the pH is alkaline and is unfavourable for pepsin to function.
Answer:
The correct option is D. Genes determine the trait of an organism.
Explanation:
Option D is correct because genes can be described as the hereditary molecules that determine the characteristics of a person.
Option A is false because each gene is made up of different nucleotide sequences.
Option B is false because genes do not occur as the same number of chromosomes. Rather, there are many genes present on a single chromosome.
Option C is false because all genes are not located in a specific location. Each gene has its specific location on the chromosome which is known as its locus.
Option E is false because genes are not units of RNA. Genes are made up of DNA.
Answer:
These gel cubes can be thought of as representing individual cells. As the cubes interact with their surroundings based on the amount of surface area and volume they have, the efficiency movement of substances in and out of cells depends on the two attributes as well. Greater surface area will mean more efficient rates of diffusion, which implies a smaller surface area to volume ratio is ideal for a biological cell.
Hope that answers the question, have a great day!
Answer:
Explanation:
Stalactites-a tapering structure hanging like an icicle from the roof of a cave, formed of calcium salts deposited by dripping water.
Stalagmites-a mound or tapering column rising from the floor of a cave, formed of calcium salts deposited by dripping water and often uniting with a stalactite.
I believe the answer is a government report.
Hope that helps! :)
