Question:- what is the net charge of the structure in the figure below?
A. 1-
B. 1+
C. 2+
D. 2-
Answer
there are 3 protons (+ve charge) and 2 electrons (-ve charges )
so net charge is positive one
The function of a bone that results from its relationship
with a skeletal muscle is that it engage in or allows movement of the limbs in
which we could see that both the bone and skeletal muscle are working together in
order to produce the limb’s movement.
Hypertrophy is the process that occurs when fat cells swell and enlarge. Hope this helps!
The disk diffusion test is used to compare the effectiveness of antibiotics. The incubated plate (results) will show bacteria growth except where antibiotic has effects. The more effective the drug, the inhibition zone will be greater. So the most effective antibiotic is the one that has the largest inhibition zone around the test site.
Answer:
The correct answer will be option E.
Explanation:
The features given in the question are the characteristics features of the group of bacteria belonging to Cyanobacteria.
These Cyanobacteria are the prokaryotes which are capable of synthesizing the food through a process called photosynthesis. These bacteria use sunlight as their energy, use water and air to synthesize food. They under anaerobic condition synthesize the nitrogen in special structures called heterocyst, a characteristic feature of cyanobacteria.
Thus, the features given in the question are:
1. contain photosystems to carry out photosynthesis.
2. producing oxygen
4. contain phycobilins
6. Hetrocysts: nitrogen-fixing structures.
7. The ancestor of plant chloroplasts.
Thus, option E is the correct answer.
