The sequence of amino acids in a protein is determined by DNA. In a protein that is present in all species, the amino acid sequence will be different. Once a protein has been chosen, the amino acid sequence of that protein in different species are compared. More similarities, or fewer differences, indicate that two species are closely related. (sorry if im wrong!)
Answer:
The system that moves blood throughout the body.
How many genes control that trait
Answer:
A. Pathogen- 4
B. aerobic- 7
C. hypothesis- 6
D. herbivores- 2
E. one another differentiation -5
F. homeostasis- 1
G. metabolism- 3
Explanation:
A. Pathogen- a pathogen is a living organism which can feed on other organism and can utilise their cellular components for their own survival. This affects the host cell and they get infected and the pathogen thus causes disease.
B. Aerobic- The oxygen appeared on Earth later compared to the time life originated on earth. Therefore some organism living today can use oxygen for survival and some not. The organism which utilises oxygen for their survival is known as aerobic microorganisms.
C. Hypothesis- The hypothesis is a predicted statement formulated based on the study related to the natural event which can explain the natural event.
D. Herbivores- The organism which cannot make food for themselves on their own but rely on another organism, especially the plants, are known as the herbivores.
E. Differentiation- Differentiation is the process which forms a variety of cells from a single cell and can perform different functions.
F. Homeostasis- is the mechanism which can maintain the internal conditions of the organisms.
G. Metabolism- refers to the chemical reactions which can help perform the normal functioning of the organism.
