Keeping in mind the life cycle of bacteriophages, consider the following problem: During the reproductive cycle of a temperate bacteriophage, the viral DNA inserts into the bacterial chromosome where the resultant prophage behaves much like a Trojan horse. It can remain quiescent, or it can become lytic and initiate a burst of progeny viruses. Several operons maintain the prophage state by interacting with a repressor that keeps the lytic cycle in check. Insults (ultraviolet light, for example) to the bacterial cell lead to a partial breakdown of the repressor, which in turn causes the production of enzymes involved in the lytic cycle. As stated in this simple form, would you consider this system of regulation to be operating under positive or negative control?

As a team of explorers travels southward from the North Pole into Canada, they encounter a dense forest of pines and other coniferousevergreens. They leave the forest before the winter, which is long and cold. Which of these biomes has the team visited?
o A. temperate grasslands
B. Northwest coniferous forest
C. tropical dry forest
O
D. boreal forest (taiga)

Answers

Among the options, the name of the biome that the team visited is known as boreal forest (taiga). Thus, the correct option for this question is D.

What is Biome?

A biome may be defined as a very large ecosystem that is tunning in nature in a very unmanaged way. It may also be characterized as a very large area that is characterized by a particular type of vegetation. Some examples of biomes may include tropical rainforests, coral reefs, grasslands, etc.

According to the context of this question, taiga (boreal forests) are the types of coniferous forests that are located below the tundra in the biome triangle. These types of biomes may have a dense forest of pines and other coniferous evergreens. They leave the forest before the winter, which is long and cold. They generally possess temperatures lower than the temperare or tropical forests.

Therefore, the name of the biome that the team visited is known as boreal forest (taiga). Thus, the correct option for this question is D.

Please help! will mark brainlist!!! Which object is hotter in terms of its kinetic energy: the cup of coffee or the iceberg? Explain the reason for your answer in terms of your understanding of the kinetic molecular theory of matter. ​

Answers

Answer:

red-hot iron bar

Explanation:

An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger.

Which phrase does not describe asexual reproduction in organisms?1-little variation in offspring
2-duplicates its genetic material
3-only one type of cell involved
4-requires two parents

Answers

It requires two parents, does not describe parthenogenesis in organisms.

The correct option is 4.

What is parthenogenesis?

Parthenogenesis is the process in which reproduction happens without the fertilization of sperm.

It is the development of an embryo without fertilization of the egg.

Animals such as bees, wasps, and ants, do parthenogenesis.

It includes only one parent.

Thus, the correct option is 4, which requires two parents.
