Answer:

Plasma tail

Explanation:

A comet is a body in space which revolves around Sun in elliptical orbit. It is composed of rocks, dust, ice and frozen gases. A comet has mainly three parts:

Nucleus- It is the core of the comet which is solid.

As the comet nears the sun, the frozen gases start sublimating. An atmosphere surrounds the nucleus which is known as coma.

As the comet approaches the sun closely, the coma extends backwards due to solar wind. The solar wind pushes the ionized gases of the comet away from the nucleus. This is known as tail. There are two tails - dust tail and plasma tail. Plasma tail is composed of ionized gases -heavier than the dust tail and thus lies below it.

If Darwin knew of Mendel’s work, how might it have influenced his theory of evolution? Do you think this would have affected how

Viktor [21]

Answer:

See explanation

Explanation:

Darwin proposed his theory of evolution on the premise of natural selection. According to him, organisms which possess favourable characteristics which enable them to survive in their environment are more likely to survive and reproduce, passing on these favourable characteristics to their offsprings.

According to Mendel, the unit of inheritance passed on from parents to offspring are genes. Hence Darwin's factors are Mendel's genes.

If Darwin knew of Mendel's work. It might have influenced his presentation of the idea of passing on favourable characteristics from parents to offspring in the light of genetics.

This would have made Darwin's work to have more empirical backing hence making it more widely accepted.

differentiate between Acute and chronic diseases ...(minimum 5 points each)......pls help fast ....i have my exam tomorrow

Viefleur [7K]

Acute diseases are sudden, severe, and short term only. They quickly appear and worsen without warning and they disappear. Examples of this are flu or colds.

Chronic diseases, on the other hand, are long-developing diseases. The symptoms have been present for long time and it worsens as time progresses. Examples of this are Osteoporosis and heart disease.

Assuming the stomata are open to the same degree, the rate of transpiration should _____ on a rainy day compared with a sunny da

Allushta [10]

Answer:

decline: decrease

Explanation:

Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.

On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.

How can scientific conclusions be reliable, but also able to be changed with the introduction of new evidence
