Answer:
<h2> Each daughter molecule contains one parent strand and one newly synthesized strand</h2>
Explanation:
In DNA replication, each daughter molecule contains one parent strand and one newly synthesized strand because DNA replication is semi-conservative. One template strand is parental strand and the other one is its complementary which is new one, which is synthesized by DNA polymerase enzyme. So both daughter molecule contains one parent strand and one newly synthesized strand and they are same in the sequence of bases because each strand contains one original parental strand.
a. In the lag phase, cell death exceeds cell division. FALSE
Is the period when the bacteria are adjusting to the environment.
b. In the death phase, bacterial growth may cease as a result of oxygen and nutrient depletion. TRUE
Is characterized by an exponential decrease in the number of living cells.
c. Bacteria typically divide by binary fission, producing two daughter cells. TRUE
This is the most common way of division. The duplicate's DNA and part in half.
d. The generation time of bacteria may vary from species to species. TRUE
As in all species, the generation time will always vary.
A medical patient is suffering from mysterious fainting spells. A medical team works to get to the bottom of the problem and identify the cause. So the correct option is B.
<h3>What is the scientific method?</h3>
The start of a scientific investigation is observation. This means anything that catches the attention of the scientist. For example, for a cancer biologist, a certain kind of cancer might be an observation that can't be treated with chemotherapy and he would wonder why it is so.
For all the sciences, the core is a problem-solving approach which is called the scientific method. There are five basic steps in the scientific method. These are:
- Observation of a phenomenon
- Questioning the reason or cause for it.
- Hypothesizing or giving a testable explanation
- Making a prediction based on the hypothesis.
- Testing the prediction.
- Using the results to develop new hypotheses or predictions.
Therefore, the correct option is B.
