Phosphorus in soil is transformed into insoluble compounds unless what happens?

Answers

Answer:

It is not absorb by the plants, it turns into insoluble form.

Explanation:

Phosphorus in soil is transformed into insoluble compounds unless not used by the plants. The insoluble phosphorus is transform into soluble form in the soil by phosphorus solubilizing bacteria. The phosphorus solubilizing bacteria helps in conversion of insoluble phosphorus into soluble phosphorus which can absorb by the plants. If the phosphorus is not absorb by the plants and present for a long time, it can be converted into insoluble form which is unavailable for the plants which can be converted back with the help of phosphorus solubilizing bacteria.

What are the causes of variations ? please explain thi also​

Answers

Answer:

variation can be caused by mutation and other things

Explanation:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light or cigerette smoke

➜ Following are the causes of variations:

Dual percentage: Offsprings inherit some features from mother and some from father. Hence no offspring will exactly resemble to either of the parent or each other.Mutation in gene or chromosomal pattern also causes variations.

How does air pressure affect
breathing?

Answers

Answer:

When you inhale, muscles increase the size of your thoracic (chest) cavity and expand your lungs. This increases their volume, so pressure inside the lungs decreases. As a result, outside air rushes into the lungs. That's because a gas always flows from an area of higher to lower pressure.

Answer:

The air pressure in your lungs has to be less than the air outside your lungs, to get your lungs to inflate. This is because air moves from high pressure areas to low pressure areas. During bad weather and at high altitudes the air pressure is lower, making it harder for us to breathe.

Answers

Complete question:

Fill in the blanks.

The earth is ______ (warming, cooling, static, dynamic). This trend most closely follows trends in the Earth's ______ (albedo, distance from the sun, energy input from the sun, atmosphere). Within the Earth's ______ (albedo, mantle, atmosphere, crust) the component that is likely most responsible ______ (carbon dioxide, magma, water, humans).

Answer:

The earth is warming. This trend most closely follows trends in the Earth's atmosphere. Within the Earth's atmosphere is the component that is likely most responsible for carbon dioxide.

Explanation:

Carbon dioxide (CO₂) is a gas that, among other gases, composes the atmosphere, mainly the troposphere, which is closest to the Earth. The balance of this gas in nature is very complex and involves interactions between the atmosphere, the plants, and the oceans.

The current increase in CO₂ is a responsible component of the greenhouse effect involved in global warming and climate change. The rise in CO₂ is possibly the best documented.

The atmospheric increase of CO₂ follows a natural fluctuation trend that has been happening throughout the whole Earth´s history. It has been proven that the current rise in CO₂ concentration overlaps the expected variation and that the reached levels at the moment exceed the highest past registered levels. This substantial increase must be related to human activities.

The immune response consists of different components playing their role for a common goal: to rid the body of a pathogen. Create an analogy that helps explain the roles of the responses of the immune system and describe the relationship between the responses.

Answers

Answer:

In a primary immune response, naive B cells are stimulated by antigen, become activated, and differentiate into antibody-secreting cells that produce antibodies specific for the eliciting antigen.

A secondary immune response is elicited when the same antigen stimulates memory B cells, leading to the production of greater quantities of specific antibodies that are produced in the primary response

how would the solar eclipse be different if the moon was moved AWAY from the earth?​

Answers

Answer:

The Sun is completely blocked in a solar eclipse because the Moon passes between Earth and the Sun. Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully blocks the Sun’s light from Earth’s perspective. Sometimes the Moon is far enough away that it doesn't create a total solar eclipse. However, once the Moon's growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won't happen for a long time though.

. Landfill are is a/an: (a) open area (b) high lying open area (c) open area near a river/lake (d) low lying open area

Answers

Answer:

d

Explanation:

Landfills are low-lying open areas specifically designed for the dumping of waste materials to be buried later.

Landfills can be for municipal/household wastes, industrial wastes, or for hazardous wastes. They are usually low lying to facilitate their burial after they must have been filled-up and they represent one of the oldest methods of disposing wastes.

Landfills are not just open areas, they are low-lying as opposed to high-lying, and they are not created near rivers or lakes.

The correct option is, therefore, d.
