what is transpiration caused by​

Answers

respiration is caused by the presence of chlorophyll in the plants and plenty of sunshine that leads to excessive loss of water in the plants

Transpiration is the loss of water from the plant through evaporation at the leaf surface. ... Transpiration is caused by the evaporation of water at the leaf–atmosphere interface; it creates negative pressure (tension) equivalent to –2 MPa at the leaf surface. Transpiration happens when plants release water vapor from tiny holes, called stomata, in their leaves. ... Transpiration increases because at warmer temperatures plants open up their stomata and release more water vapor. Humidity – If the air around the plant is too humid, the transpiration and evaporation rates drop. Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. ... But air that is not fully saturated with water vapor (100% relative humidity) will dry the surfaces of cells with which it comes in contact. Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis. ... This transpired water must be replaced by the transport of more water from the soil to the leaves through the xylem of the roots and stem. Transpiration is the process in which plant roots absorb water and then release the water in the form of vapour through the leaves. Transpiration is an important factor in the water cycle as it is one of the major sources of water into the atmosphere. Definition of Transpiration: Transpiration is the process of water movement through a plant and its evaporation from aerial parts especially from leaves. Its Type: Cuticular Transpiration. Lenticular Transpiration. Stomatal Transpiration. The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.

(a) Predict what would happen if, after 22 months, guppies from the transplanted population were returned to the source pool. (b) Describe an experiment to test your prediction.

Answers

Based in the experiment with the guppies, it can be concluded that natural selection is a factor of evolution.

What is a hypothesis?

A hypothesis is an explanation put forward to explain an observation without prior testing.

From the observations in the guppies;

The question is whether natural selection is favors coloration in guppiesThe hypothesis is that natural selection determines coloration in guppies The prediction is that guppies with bright coloration will thrive in a predator free environment The control group is the source poolthe experimental group is the transfer poolthe conclusion from the data is that guppies with bright coloration are naturally selectedReturning the guppies from the transfer pool to the source pool will essentially reduce the population of the bright colored guppies due to predation.

Therefore, it can be seen from the guppies that natural selection drives evolution of species.

Karissa is conducting an experiment on the amount of salt that dissolves in water at different temperatures. She repeats her tests several times using the same procedure. What can Karissa do to further increase confidence in the results of her experiment?

Answers

Answer:

She could time how long it takes for each amount of salt dissolves in the waters. (as well as keep each amount of salt the same if she was not doing that already.)

Explanation:

This way, she could observe which water is best for dissolving solvents and which is most affective in the shortest amount of time. If she was not timing how long it takes for salt to dissolve in different temperatures of water, then the experiment may as well have been useless unless there is somehow a different objective.

How does smoking cause bladder cancer? Write a concise answer to this question using scientific language effectively

Answers

If you smoke for many years, these chemicals pass into your bloodstream and are filtered by the kidneys into your urine. The bladder is repeatedly exposed to these harmful chemicals, as it acts as a store for urine.

Smoking irritates the bladder and can make IC symptoms worse. Incontinence (leaking urine) and Overactive Bladder (OAB), impact more than 33 million men and women. Smoking bothers the bladder and can cause frequent urination. It can also cause coughing spasms that can lead to urine leakage.

This can cause changes to the cells of the bladder lining, which may lead to bladder cancer.

If light color is a recessive trait and the trees stay dark forever, could the light colored moths eventually become extinct? Why or why not?

Answers

Answer:

The light moths could become extinct eventually

Explanation:

If trees stay dark forever the light moths are easier to prey upon and eventually negative selection pressure will decrease the population of light moths until it is virtually nonexistent.

For a real life case of this, look into pepper moths and the Industrial Revolution.

If the light-colored trait is truly recessive, the moths may still carry the gene and could reappear in future generations.

What is a recessive trait?

A recessive trait is a genetic characteristic that is only expressed when an individual inherits two copies of the recessive gene, one from each parent. In other words, a recessive trait is only observable when the dominant version of the gene is absent.

For example, if a person inherits a dominant brown-eye gene from one parent and a recessive blue-eye gene from the other parent, they will have brown eyes, as brown is the dominant trait. However, if both parents pass on the recessive blue-eye gene, the individual will have blue eyes, as there is no dominant gene present to override the recessive gene.

All the ecosystems on Earth are collectively referred to as the biosphere. Therefore, it comprises both live things and inanimate objects, such as sunshine and water. Thus, option B is correct.

What is the role of sunlight in biosphere?

Photosynthesis is a process that organisms like plants, algae, and cyanobacteria used to turn carbon dioxide and water into organic molecules like carbohydrates.

The primary source of organic matter in the biosphere is this mechanism.

The sun powers the biosphere. This is so because the biosphere depends on the sun for its source of energy.

The compounds known as photosynthetic pigments catch the solar energy that powers the biosphere and use it to create organic molecules out of carbon dioxide and water.
