We could say that there are five steps in scientific method: observation, hypothesis, prediction, experiment and conclusion. Observation is the first step and we could also call it research. In this step we must understand the problem in the right way. The hypothesis is the possible answer, based on the research. Prediction is even more specific than the hypothesis: on this stage, you must know how will you demonstrate that your hypothesis is true. Experiment tests your hypothesis and shows whether your hypothesis was true or false. After that you can proceed to making conclusion, which summarizes the experiment's results, and tells do the results match up to hypothesis and in which way.

What is checked in the GAP 2 stage of interphase?
EleoNora [17]

During the second gap, or G2 phase, the cell continues to grow in size and produce proteins necessary for cell division. Microtubules, filamentous internal structures, necessary for separating the chromosome copies are made during this phase. The second internal checkpoint that determines if the cell can continue through its cycle occurs in G2. While the G1 checkpoint checks to verify DNA is error free before replication, the checkpoint in G2 confirms the new DNA is error free after replication

Which of these diseases results in meningitis caused by an encapsulated yeast?
amid [387]

Answer:

cryptococcosis

Explanation:

Cryptococcosis

It is an air-borne disease. It is caused after inhalation of soil which is contaminated by encapsulated yeast, Cryptococcus neoformans or C. gattii. The soil is infested with yeast which are contained in the waste of the birds. This disease affects the lungs since it is caused by inhaling the Cryptococcus. Cryptococcus can spread to skin and other organs, also involving the brain and meninges alongwith bones and joints.

Symptoms

Meningitis is common and can be discovered by symptoms like headache, vision problems and changes in behavior.

Lesions and ulcers on the skin which are similar to acne, are another sign of this disease.

Coccidioidomycosis

Another air-borne disease caused by inhaling dust containing spores. It is caused by Coccidioides fungus.

This disease, if ignored, can lead to severe damage to the respiratory organs, bones and/ or heart.

Visible symptoms include tiredness, fever, rashes and pain.

People with weaker immune system are easy victims of severity of this disease.

Candidiasis

This is caused by the yeast, Candida albicans. The skin and mucous membranes are the commonly affected areas. Candidiasis of the mouth results in thrush, which is usually found in infants. Vagina is another common area which is affected by this disease.

Histoplasmosis

This is the result of inhaling fungal spores which are carried by air. The lungs are the first organs to be affected. Initial symptoms include fever, cough, pain and bumps. More serious complications are indicated by blood in the cough, shortness of breath and heavy sweating.

Prevention

All the diseases discussed above are air borne diseases. The respiratory system is affected the most followed by the brain, since the microbe are easily spread through the body.

The most important prevention is the diet which helps boost the immune system. Another important prevention is cleanliness which is to be maintained until medical help becomes available.

motikmotik

Answer:

The correct answer will be option-D

Explanation:

The process of photosynthesis release oxygen from the plant which is used by the organism on earth during cellular respiration.

The oxygen released by the plants is formed through the splitting of water molecules as a result of the transfer of electrons through the electron transport chain in the thylakoid membrane during the light-dependent reaction.

Since the released oxygen is the result of the light-dependent reaction and not the light-independent reaction or Calvin cycle where heavy oxygen isotope is utilized in the cycle.

Thus, option-D is the correct answer.
