a. Viruses reproduce using a ______ _____.



b. What are the differences between proviruses and viral DNA?



c. Why is the common cold virus so difficult to cure?

Answers

Answer 1

Answer:

Viruses reproduce using a host cell

The differentce between proviruses and viral DNA is A provirus is a virus genome that is integrated into the DNA of a host cell. In the case of bacterial viruses (bacteriophages), proviruses are often referred to as prophages. However, it is important to note that proviruses are distinctly different from prophages and these terms should not be used interchangeably.

Common cold virus is difficult to cure because Unfortunately, antibiotics — medications that treat bacterial infections — cannot treat or cure a common cold. That's because colds aren't caused by bacteria. Some people report that they've had a cold, took antibiotics, and felt better after a few days of the medication.

Answers

Answer:

They evolved on land to begin with from earlier now extinct groups groups so there was no need to adapt to life on land, other than to adapt to different terrestrial environmental pressures. Land can be everything from next to a river to a hot desert to rocks to Antarctica, and plants grow in all those places.

An instrument is gradually lowered beneath the surface of the ocean to measure the temperature and salinity of the water. The graphs below show the change in temperature at each depth in kilometers below the surface.

Image of two graphs. The left graph has the x axis labeled temperature degree C ranging from 0 to 10. The y axis is labeled depth below surface, km, ranging from negative 1.8 to 0. The line on graph goes up vertically starting at about 2 degree C on the x axis and negative 1.9 km on the y axis. The vertical line goes up staying at about 2 degree C and climbs from negative 1.9 km to about negative 0.8 km. The line starts to shift right at negative 0.6 km. The line shifts to the right from 2 degree C to 5 degree C. The line shifts to right more starting at negative 0.5 km and reaches 10 degree C around negative 0.2 km. The line continues up vertically after negative 0.2 km. The right graph has the x axis labeled salinity ranging from 33.8 to 34.6. The y axis is labeled depth below surface, km, ranging from negative 1.8 to 0. The line on the graph starts at 34 on the x axis and 0 km on the y axis. The line starts to shift to the right at negative 0.1 km and levels out at 34.2 on the x axis. At negative 0.2 km the line shifts to the left and continues to shift left until it reaches negative 0.5 km. The line starts to shift to the right again at negative 0.6 and continues to shift right until it reaches negative 1.9 km on the y axis and 34.6 on the x axis.

What is an ocean?

An ocean is a large body of salt water. The oceans are divided into seven kinds. But they are interconnected to each other. The ocean is the largest water body, and it is also present in the form of freeze blocks of ice.

The graph is given of the temperature and salinity of the ocean, with the depth of the ocean the temperature of the ocean decreases, and the salinity increases.

The salinity of the water represents the presence of salt in the oceans. It. the graph proves that the salinity increases with the depth, coming closer to the depth.

Thus, the correct option is B.) The salinity increases as the depth goes closer to zero.

Answers

The most valid conclusion concerning ocean depth temperature is B. The salinity increases as the depth go closer to zero.

 

Effect of Salinity on Water Depth

Decreasing ocean temperature increases ocean salinity. These occurrences put pressure on water as the water depth increases with decreasing temperature and increased salinity.

 

What is Ocean Salinity?

Ocean Salinity refers to the saltiness or amount of salt dissolved in a body of water. The salt dissolution comes from runoff from land rocks and openings in the seafloor, caused by the slightly acidic nature of rainwater.

 

Thus, the most valid conclusion one can draw regarding ocean depth temperature is Option B.

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?

A. Biome
B. Community
C. Ecosystem
D. Habitat

Answers

Answer:

habitat

Explanation:

The ecological levels do not describe interacting biotic and abiotic factors in an area's habitat. The correct option is D.

What is a habitat?

A habitat is a place where physical or biotic factors are presented. This is a place where all the factors are present to live a species with all suitable conditions.

Habitat of different species is different. They live in their suitable habitat to grow and reproduce accordingly. If a species is moved from its habitat, then it may have difficulties in surviving.

So habitat is not a place where all biotic and species abiotic factors are present, it is a place where all living factors are present that are necessary for the living of a person. So, it is not the ecological level of  interacting biotic and abiotic factors in an area

Thus, the correct option is D. Habitat.

Answers

Answer:

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest

Before that we lived on Loomis on the third floor, and before that we lived on Keeler. Before Keeler it was Paulina, and before that I can't remember. But what I remember most is moving a lot. Each time it seemed there'd be one more of us. By the time we got to Mango Street we were sixMama, Papa, Carlos, Kiki, my sister Nenny and me.Chunk 1 annotation: The house on Mango Street is ours, and we don't have to pay rent to anybody, or share the yard with the people downstairs, or be careful not to make too much noise, and there isn't a landlord banging on the ceiling with a broom. But even so, it's not the house we'd thought we'd get.Chunk 2 annotationWe had to leave the flat on Loom is quick. The water pipes broke and the landlord wouldn't fix them because the house was too old. We had to leave fast. We were using the washroom next door and carrying water over in empty milk gallons. That's why Mama and Papa looked for a house, and that's why we moved into the house on Mango Street, far away, on the other side of town.Chunk 3 annotationThey always told us that one day we would move into a house, a real house that would be ours forever so we wouldn't have to move each year. And our house would have running water and pipes that worked. And inside it would have real stairs, not hallway stairs, but stairs inside like the houses on TV. And we'd have a basement and at least three washrooms so when we took a bath we wouldn't have to tell everybody. Our house would be white with trees around it, a great big yard and grass growing without a fence. This was the house Papa talked about when he held a lottery ticket and this was the house Mama dreamed up in the stories she told us before we went to bed.Chunk 4 annotationBut the house on Mango Street is not the way they told it at all. It's small and red with tight steps in front and windows so small you'd think they were holding their breath. Bricks are crumbling in places, and the front door is so swollen you have to push hard to get in. There is no front yard, only four little elms the city planted by the curb. Outback is a small garage for the car we don't own yet and a small yard that looks smaller between the two buildings on either side. There are stairs in our house, but they're ordinary hallway stairs, and the house has only one washroom. Everybody has to share a bedroomMama and Papa, Carlos and Kiki, me and Nenny.Chunk 5 annotation Once when we were living on Loomis, a nun from my school passed by and saw me playing out front.The laundromat downstairs had been boarded up because it had been robbed two days before and the owner had painted on the wood YES WE'RE OPEN so as not to lose business.Where do you live? she asked.There, I said pointing up to the third floor.You live there? There. I had to look to where she pointedthe third floor, the paint peeling, wooden bars Papa had nailed on the windows so we wouldn't fall out. You live there? The way she said it made me feel like nothing. There. I lived there. I nodded.I knew then I had to have a house. A real house. One I could point to. But this isn't it.
