Which of the following conclusions is supported by the data?
A. The optimum pH of the enzyme is 6.6.
B. The optimum pH of the enzyme is 5.8.
C. The enzyme's activity is greater around pH 8.0 than around
pH 5.0
D
The enzyme's activity continually increases as pH increases
from 5.0 to 9.0
Answers
Answer:
A
Explanation:
A. The optimum pH of the enzyme is 6.6. - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)
B. The optimum pH of the enzyme is 5.8. - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80
C. The enzyme's activity is greater around pH 8.0 than around pH 5.0 - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.
D . The enzyme's activity continually increases as pH increases from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

Help MEH!!!! plz Which feature may form as a result of erosion related to runoff?
O deltas
O gullies
O flood plains
O stalactites
Answers
Gullies are a feature that may form as a result of erosion related to runoff. It may produce the transfer of water from fields to adjacent land.
What is runoff erosion?Runoff erosion is a natural process that produces the transfer of water from fields to adjacent land.
The runoff may lead to erosion because the eroded material in the soil can be deposited a significant distance away.
This process (runoff related to erosion) occurs when there is more water or any other substance (for example, pesticides) than the land/soil can absorb.

Many small accessory bones, such as sesamoid bones, are not included in this count.
The axial skeleton, comprising the spine, chest and head, contains 80 bones. The appendicular skeleton, comprising the arms and legs, including the shoulder and pelvic girdles, contains 126 bones, bringing the total for the entire skeleton to 206 bones. Infants are born with about 300 bones with most of it being cartilage, but will later fuse together and decrease over time to 206 bones.

A. The nucleus contains the chromosomes
B. The ribosomes assist in protein synthesis
C. Plastids store starch made during photosynthesis
D. mitochondria produce energy through respiration
Answers
Answer:C. Plastids store starch made during photosynthesis
The statement that describes plant cells but not animal cells is the plastids that store starch made during photosynthesis. Thus, the correct option for this question is C.
What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
Animal cells do not perform photosynthesis so they do not have plastids. Plastid is a type of cell organelle which is specific to only plant cells that significantly store starch that is synthesized during the process of photosynthesis.
Animal cells have cell organelles like mitochondria, endoplasmic reticulum, etc. while chloroplast and plastids are specific to plant cells.
Therefore, the statement that describes plant cells but not animal cells is the plastids that store starch made during photosynthesis. Thus, the correct option for this question is C.

I hope that this helps you!
The correct statements that describe the structure of cell membrane are:
Proteins, lipids, and carbohydrates are found in and on the cell membrane.A phospholipid bilayer forms the semipermeable cell membrane.The plasma membrane or cell membrane of organisms is made up of a bilayer of phospholipids in which proteins, carbohydrates, glycoproteins, and glycolipids are embedded. In animal cells, there is cholesterol too.
The biological membranes of cells are made up of two layers of phospholipid. Each layer contains a lipid tail attached to a polar head. The head is polar in nature directed both outward toward the environment of the cell and inward toward the cytosol.
In this way, a hydrophobic region of lipid tails separates the solution into two parts. That makes it a semipermeable membrane.

D
Explanation:
Well, animal cells use simple sugars, like glucose. The simple sugars are the only ones small enough to pass through cell walls. We use ATP to access the energy in the sugars. Cells can either use a aerobic system (using oxygen) or an anaerobic system to metabolize sugars. Humans generally use the aerobic system although in some cases our cells are forced to use the anaerobic system.

Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances interact with water?
Answers
Answer: Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
Explanation: Nonpolar molecules do not dissolve easily in water. They are described as hydrophobic, or water fearing. When put into polar environments, such as water, nonpolar molecules stick together and form a tight membrane, preventing water from surrounding the molecule.
