Answer:
DNA replication is the process by which a molecule of DNA is duplicated. When a cell divides, it must first duplicate its genome so that each daughter cell winds up with a complete set of chromosomes.
Explanation:
Answer:
TRUE
Explanation:
If the population follows a logistic growth curve, the graph of P vs t will look like the diagram below.
The rate of growth (P') increases slowly at first, then increases rapidly from 2 to 4, and then slows down, but always P > 0.
The graph has an inflection point at (3, 1000). That's the point at which the rate of growth starts slowing down.
When t < 3, P'' > 0.
When t = 3, P'' = 0.
When t > 3, P'' < 0, because the rate of population growth is slowing down.
Thus, if the population is in the final phase of logistic growth, the population is increasing at a decreasing rate (TRUE)..
Answer:
The answer is sunlight.
Explanation:
Sunlight is captured from the plants leaves and that energy is used to break down water into hydrogen and oxygen.
The correct answer is option (C) One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table. Measuring liquids by holding the flask at eye level is the greatest amount of error in the experiment.
When liquid is being measured in a flask, the liquid shows a curve downwards which is called the meniscus. For measuring the transparent liquids, the lower meniscus touching the graduation of the should be considered and for measuring the colored liquids, the upper meniscus touching the graduation of the flask should be considered. When, the measurement is done by holding the flask at eye level there is always an error as it should be kept on a flat surface and measured by eyes directly leveling with the liquid. This gives a correct measurement which was done by the other student. Thus, one student measuring the liquid by holding the flask at eye level will have a wrong measurement and the other student measuring the liquid while the flask sits on the table gives the correct measurement and the results of the experiment will vary.
