Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled. If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.
Hope this helps.
Spontaneous mutations in the bacterias DNA
The correct answer is: A. A change in a cell's genetic material.
Mutations occur in DNA as a result of mistakes during the DNA replication (when repair mechanisms don’t fix it) or as the result of environmental factors (e.g. UV light). Mutations can have positive impact, by increasing the genetic variation or can have negative effect, causing the diseases or cancer.
Answer:
The mismatch pair is plasmodium causes chagas disease. Chagas disease occurs due to Trypanosoma cruzi.
Explanation:
Chagas disease is a parasitic disease .It also known as American Trypanosomiasis. Chagas disease is occurs due to the <u>Trypanosoma cruzi</u> parasite.It is spread mostly by insects .The name of the insect is Triatominae, or "kissing bugs". The symptoms change during the course of the infection.
Plasmodium is a protozoan parasite which causes malaria in the human body.
Giardia is a microscopic parasite. It has been contaminated with feces (poop) from infected humans or animals.So this match is correct.
African sleeping sickness caused by a microscopic parasite species <u>Trypanosoma</u> <u>bruce</u>i. It is transmitted by the tsetse fly , which is found only in rural Africa.
Histoplasmosis (Ohio valley fever) is a fungal infection which causes by Histoplasma .It generally effect on lungs and immune system.
Trichomoniasis (or “trich”) caused by infection with a protozoan parasite called<u> </u><u>Trichomonas</u> <u>vaginalis</u>.Its a sexually transmitted disease (STD).It cause foul smelling in women vagina.
