<span>In a single cell organism, the
absorption of nutrients and control of certain things to <span>come inside or go outside the cell directly involves
the cell membrane. Although, the basic function of the cell membrane is to
protect the cell from its surroundings. It also facilitates the transport of
substances needed for survival.</span></span>
D. endothermic
Explanation:
Since the chemosynthesis reaction uses up heat and other inorganic compounds to produce food for themselves, the process is endothermic.
- In an endothermic reaction, heat is absorbed from the surrounding.
- The surround will then become colder at the end of the reaction.
- Since the chemosynthesis reaction uses up heat, it is an endothermic reaction.
- Exothermic reactions liberates heat to the surrounding.
- The surrounding becomes hotter at the end of the change.

Answer:
Δy=0.431m
Explanation:
Diffraction grating with split space d,to find the fringe position ym,we must to find the angle from
dSinα=mλ
A grating with N slits or lines per mm has slit spacing of
d=1/N
d=(1/600mm)
d=1.67×10⁻³mm
For 400nm wavelength:
α=Sin⁻¹(mλ/d)
And the position of first order lowest wavelength fringe on the screen is:
For 700nm wavelength:
α=Sin⁻¹(mλ/d)
And the position of first order highest wavelength fringe on the screen is:
The difference between the first order lowest and highest wavelength fringe is
Δy=(0.925595 - 0.49445)m
Δy=0.431m
Answer:
The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as system's mass cannot change, so quantity can neither be added nor be removed.
