Answer:
Glucose is a six-carbon sugar that is directly metabolized by cells to provide energy. ... A glucose molecule is too large to pass through a cell membrane via simple diffusion. Instead, cells assist glucose diffusion through facilitated diffusion and two types of active transport.
Explanation:
Answer: 2
Explanation:- Mechanical advantage is the ratio of the output force to the input force.
Mechanical advantage=
Given:
Input force = 320 N
output force= 640 N
Answer: C. Prevailing winds
Explanation:
Several factors influence the direction of the sea current, and the prevailing wind is one of them. Surface winds are certainly one of the most critical factors affecting the direction of movement. In addition to this factor, the evolution of the sea current is also influenced by the earth's rotation, temperature, the attractive force of the moon and river flows.
Answer: Option B
Explanation:
The glucose is the basic unit of energy. It is absorbed by the cells of the body. The glucose that is taken inside the body by the means of food is utilized to gain energy.
The glucose that is absorbed from the food moves to interstitial spaces before going inside the cell.
100% of the glucose is transferred from the interstitial spaces of the cell to the inside of the cell.
This is because more amount of the glucose is still outside the cell as it is absorbed completely.
The missing part of the question is as follows:
Phrase indicates a limit to the scientific accuracy of the experiment?
Answer:
The correct answer is - a sample size of 300 people.
Explanation:
In the given research Marcus developed a drug that is already 200,000 people taking the drug, and the scientist takes sample size of only 300 people for the experiment.
The sample is very small as compared to the total population who participated in the research. A sample size of 300 people is very small compared to 200,000 people. Such a small sample size will not give the proper idea and any effective result, there would be chances to miss some aspect or effect of the drug to be missed, so, this can be the limiting factor to the experiment.
