Answer:
A testable question is one that can be answered by designing and conducting an experiment. The answers to a testable question can be observed and measured. Hypothesis- a testable explanation of an observation. A hypothesis is NOT just an educated guess about what you think will happen.
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.
Answer:
The correct answer is option C.
Explanation:
PAX5 refers to the member of the Pax gene family, which is, accountable for conducting the genetic information, which will encode the Pax-6 protein. It functions as a master control gene for the maturation of eyes and other sensory organs. Pax6 functions as a regulator in the formation of patterns and coordination needed for the proliferation and differentiation to take place effectively. This ensures that the procedures of oculogenesis and neurogenesis are taking place efficiently.
The PAX6 gene was the outcome of evolution in earlier animals comprising eyespots or eyes. The similar PAX6 gene generates distinct kinds of eyes in distinct species because of the difference in its control of PAX6 expression. At the time of the evolution of vertebrates, the biological clock opsin’s rh gene was chosen as a gene for visual receptor pigments.
From the right atrium, blood will flow through the tricuspid valve into the right ventricle.
Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
