Two bodies of water that are approximately the same size depth and latitude are found to have a large difference in the number of species inhabiting them what is likely the contributing island biogeography factor resulting in a difference in the number of species found in each body of water?

Answers

Answer:

Due to the presence of suitable environment.

Explanation:

Suitable environmental conditions are responsible for the presence of large amount of species in water bodies because suitable environmental conditions provides necessary materials for the growth and survival of organisms. The marine environment that have sufficient amount of food, space, optimum temperature, pH and salt concentrations so in this environment more number of species are present due to increase in population as compared to those ecosystem having harsh environmental conditions.

Which statement correctly
compares humidity in warm and cold air?

A. Warm air holds less moisture than cold air.

B. Warm air will always hold the same amount of moisture as cold air.

C. Warm air can hold more moisture than cold air.

D. Neither warm or cold air can contain water vapor.

Answers

Answer:I believe it is c, it makes the most sense to me. I apologize if I’m wrong

Explanation:

The statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.

What is Humidity?

Humidity may be defined as the amount of water vapor present in the atmosphere of living organisms or an ecosystem. If there is a lot of water vapor in the air, the humidity will be high. The higher the humidity, the wetter it feels outside. On weather reports, humidity is usually explained as relative humidity.

High humidity levels are more likely found in warm air. This is because warm air holds more water at higher temperatures. Due to this, warm air has the capacity to hold a lot of moisture.

But on contrary, fewer humidity levels are more likely found in cold air. This is because cold air holds less water at lower temperatures. Due to this, cold air does not have the capacity to hold a lot of moisture.

Therefore, the statement which correctly compares humidity in warm and cold air is that warm air can hold more moisture than cold air. Thus, the correct option for this question is C.

if perimeter of a square is 24cm find its area please give me easy formula​

Answers

Answer:

4l = 24

so l=6

now

l*l =6*6

= 36 square cm

Answer:

36cm²

Explanation:

Perimeter of a square = 4x (sum of all 4 sides)

Perimeter = 24 cm (given)

[tex]\implies [/tex]4x = 24

x = 24/4 = 6 cm

Now, area of a square = (side)²

Area = (6)²

= 36 cm²

Rabbits must be always aware of predators that may catch and eat them. In
natural selection what would we consider these predators?

Answers

anything higher in the food chain

Answer:

There are many rabbit predators that will attack or eat the rabbit, including man. In fact, rabbits have more than most.

Explanation:

Depending in which part of the world you live, will determine the most likely predators you need to be aware of. With domestic/pet rabbits, perhaps the most common predators are pet dogs, pet cats and foxes. However, don't think these are the only ones. Many people are surprised to learn that large birds are a predator to rabbits, especially if the rabbit is a baby, young or a small breed type. Such birds, depending on where you live, include Hawks, Sparrow  Hawks, Owls, Falcons, and kestrels. Other rabbit predators include Weasels, ferrets, badgers, stoats and snakes.

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and body aches, typically occur two to seven days after infection by the virus. This information suggests that the reproductive cycle of the SARS virus is - lysogenic, because the virus is a coronavirus. lysogenic, because the virus is a coronavirus. lysogenic, because the virus primarily affects older people. lysogenic, because the virus primarily affects older people. lytic, because the virus causes respiratory illness. lytic, because the virus causes respiratory illness. lytic, because of the quick onset of symptoms after infection.

Answers

Answer:

lytic, because of the quick onset of symptoms after infection

Explanation:

As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.

The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.

lytic, because of the quick onset of symptoms after infection
