Which best describes the lytic and lysogenic cycles?Unlike the lytic cycle, the lysogenic cycle involves production of virus particles.
Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
Symptoms of infection appear in the lysogenic cycle but not in the lytic cycle.
For virulent viruses, the lysogenic cycle is the main way of replicating.

Answers

Answer 1

Answer:

Answer: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host

Lysogenic cycle is a method by which virus can replicate its DNA using the host cell mechanism. During this phase bacteria integrate its DNA in to host cell to make viral copy to infect the organism.

The lytic cycle is another way of the viral replicaton, it results in the destruction of infected cell and its membrane. In this cycle bacteria make viral DNA and viral protein and break and allow the newly produced virus to leave and now integrated to new cells to spread infection to other cell.

Answer 2

Answer: The answer is: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.

In the lysogenic cycle a virus does not kill the host. Regarding the other statements, in the lytic cycle symptoms of infection appear, and, also, it is the main way of replicating virulent viruses.

which term describes a mechanism by which the internal conditions of an organism are kept at set values without regard to the external conditions?

Answers

The answer is homeostasis.

Homeostasis is a mechanism which controls internal conditions of an organism so that internal conditions remain stable without regard to the external conditions. So, it regulates body temperature, water level, sugar level, etc. It works through negative feedback mechanism. For example, if body temperature is increased, the body detect the change and activate mechanisms that decrease body temperature. Without homeostasis, the organisms could not survive.

Assignment: Unit 08 CFUQuestion 11 of 20
What DNA sequence is complementary to the following:
CCG ATC AAC GAT
(5 points)
CA. GGG TÁC TTG CTA
B. GGC UAG UUG CUA
c. GGC TAG TTG CTA
Question 12 of 20

Answers

The DNA sequence complementary to CCG ATC AAC GAT would be GGC TAG TTG CTA.

DNA Base-pairing

According to the base-pairing rule of DNA, Adenine (A) always pairs with Thymine (T) while Guanine (G) always pairs with Cytosine (C)

Thus:

Original sequence: CCG ATC AAC GAT

Complementary sequence: GGC TAG TTG CTA

Meat is not a good source of protein because it does not provide the body with all the essential amino acids.a. True
b. False

Answers

Answer: False.

Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.

These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.

Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

Answer:

False

Answers

As far as I know about black snails is the fact that the Black Mystery belongs to the genus Pomacea, Ampullariidae family. This family is also often called Apple Snail, and it contains a nearly 120 different species of snails. I know that increase in the number of black snails can best be explained by the high teperature in which black snails are. It's the main reason of their reproduction.
