Which of the following statements is true? In the lysogenic cycle, the virus uses the host cell to make new viral parts.
In the lytic cycle, the virus hides in the host’s DNA.
Stress can cause a virus to switch from the lytic cycle to the lysogenic cycle.
Stress can cause a virus to switch from the lysogenic cycle to the lytic cycle.

Answers

Answer 1

Answer:

Answer:Option d

Explanation:

The virus cannot live in the environment without the host cell. They need the host cell for their survival.The virus incorporates its genetic material in the genetic material of the host cell to live. They opt for lytic cycle or lysogenic cycle.

Due to environmental stressors such as the starvation or exposure to chemicals may cause the virus to switch from the lysogenic cycle to lytic cycle.

Answer 2

Answer: Stress can cause a virus to switch from the lysogenic cycle to the lytic cycle.

In order for a population to survive, sexual reproduction must produce A) more females than males. B) more males than females. C) more offspring that can survive and reproduce. D) a large number of self-fertilized individuals.

Answers

The answer is C) more offspring that can survive and reproduce.

In order for a population to survive, there must be enough offspring at least to maintain the number of population. It is better if there are more offspring able to survive and reproduce and species evolved different strategies to achieve this, such as care for the offspring.
On the other hand, neither more males nor more females will help a population to survive. There will be no variability in a gene pool because one male will cross with many females and vice versa. And with greater variability of characteristics, the greater is the chance to survive. Also, a large number of self-fertilized individuals could not be the right answer because this is an example of asexual (self-fertilization) reproduction.

c. more offspring that can survive and reproduce.

Cells undergo differentiation during embyonic development. An individual skin cell develops differently from a muscle cell because Question 7 options: the cells have different DNA. The cells have different genes. The cells express different genes. The cells have different chromosomes.

Answers

Hello!

Answer:

Option 3: the cells express different genes.

Explanation:

While all cells contain the same genes (the DNA does not change based on cell function), cells can choose to express different genes during the differentiation process so they become specialized for different functions.

In this case, skin cells may begin to develop with high concentrations of strengthening proteins such as keratin and collagen, in order to carry out their main functions e.g. to act as a strong barrier against parasites, bacteria, etc.

Whereas muscle cells may have less of these proteins because their function is different, and instead may focus on developing more mitochondria to provide energy to carry out their main jobs (movement).
