Answer:

Mutations

Explanation:

The term "mutation" describes a change that occurs in the DNA sequence of an organism. This change can be attributed to a great variety of reasons, such as mistakes when the DNA is copied, or due to environmental factors. This change contributes to the evolutionary process, and allows an organism to modify its structure and attributes.

What is true of lithospheric plates?
klemol [59]

Answer:

A. They are constantly moving. I think.

Explanation:

Each lithospheric plate is composed of a layer of oceanic crust or continental crust superficial to an outer layer of the mantle. Containing both crust and the upper region of the mantle, lithospheric plates are generally considered to be approximately 60 mi (100 km) thick. Earth's tectonic plates may have taken as long as 1 billion years to form, researchers report today in Nature. The plates — interlocking slabs of crust that float on Earth's viscous upper mantle — were created by a process similar to the subduction seen today when one plate dives below another, the report says. A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.

Which organelle is found in both eukaryotic cells and prokaryotic cells:
Ludmilka [50]

Answer:

c. Ribosomes

Explanation:

Ribosomes can be found in eukaryotic and prokaryotic cells.  In eukaryotes they are distributed by the cytoplasm, or trapped in the membranes of the endoplasmic reticulum. In prokaryotes they are found free in the cytoplasm.  In both cells, ribosomes intertwine into an RNA molecule and form polysomes.

Ribosomes are made up of two subunits, the two parts are made up of RNA molecules and proteins. This molecule has the main function of protein synthesis, that is, it is through it that aminoacids reconcile to produce proteins.

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.
