a: animals evolved from simpler forms
Hey!
What let us know what are non-renewable resources:
Resources which can’t be renewed again after usage , it takes millions of year to form them again
These include fossil fuels
If we go on using fossil fuels it will be empty and we will run out of it.
A energy resource like fossil fuels is an non renewable! But why? Because rate of consumption is more than the rate of formation !
To sustain them , we must adapt to using of Renewable resources like Wind energy, hydro , wind etc .
I hope it’s clear!
Have a good day :)
Answer:
The correct answer is option C.
Explanation:
Cardiac muscle is present only in the Heart of organisms which is involuntary in its action. The heart helps the blood to pump throughout the body.
Cardiac muscle shows the presence of intercalated discs which contain desmosomes and gap junctions. It is the presence of these gap junctions the muscle cells of the heart functions as a single functional unit due to the transmission of depolarizing current from cell to cell to different chambers of the heart.
Thus, option C is the correct answer.
<span>Sedimentation - uses solutions of lower specific gravity than the organisms, which concentrated in the sediment. This technique is recommended for general diagnostic laboratories because it is easy to perform and less prone to technical errors.
Flotation - this technique uses solutions of higher specific gravity than the parasitic organisms so the organisms float and the debris sinks producing a cleaner material while the disadvantage is that walls of cysts and eggs collapse that may blocking its identification.<span>
