What is a hypothesis?
earnstyle [38]

Answer: D.) a suggested answer to a problem

Explanation:

A hypothesis is a supposition, suggested answer or a proposed explanation based on limited evidence which can be use to start an investigation. A hypothesis is more than a guess but less than a established theory and it can be tested through study and experiments.

<u>A hypothesis is part of the scientific method </u>because it is a prediction which can be tested and the results from those experiments may disprove a hypothesis, but can never entirely prove one.

It is not a conclusion because it is an idea which tries to explain an observation. It is not information collected from experiments because hypothesis are formulated before carrying out the experiments and it is not a widely accepted idea because it just proposes a tentative explanation about a phenomenon.

The ozone layer protects life on Earth by absorbing harmful ultraviolet radiation. The ozone layer is located between 17 kilomet
Zolol [24]
The correct answer is (2) - Stratosphere. Ozone is found in the stratosphere , a layer beginning between 6 and 10 miles above the earth's surface and extends upward to about 30 mile above the surface of he earth. The ozone that is found in the stratosphere absorbs most of he harmful ultraviolet sunlight and is thus called the "good ozone" Ozone is also found in the lower region of the atmosphere known as the troposphere. But the ozone here strongly reacts with molecules causing toxicity in plants. The ozone is therefore termed as "bad ozone."

Part C
AnnyKZ [126]

The style is the female reproductive part of the plant. it plays important role in plant breeding .

What is style and the role of style in reproduction ?

The stigma and ovary are connected by a long tube-like structure called the style. The pollen tubes bearing male gametes enter the style tissues and travel to the ovary's ovule once the stigma's pollen grains have germinated. Once within the embryo sac, it travels to the egg cell to fertilize it with the aid of the filiform apparatus.

The style is crucial to the plant reproduction  process since it not only serves as the site for the formation of the pollen tube but also functions to prevent incompatible pollen from entering the ovary. Genetic information is transferred between the pollen and the plant when the pollen tube begins to spread within the style. The plant also produces a poison at this period. The plant will release the poison to block the formation of the pollen tube if the pollen is unsuitable because it comes from a different species or is too closely related, leading to inbreeding.

If the pollen is compatible, the plant will isolate the poison and sequester it so that the pollen tube growth is not halted. Therefore, the style is the area where compatibility is evaluated and where it is decided if pollen that falls on a flower will be allowed to fertilize the plant.
