TRUE. Roots have tiny root hairs that maximize the plant's ability to absorb water.
Root hairs are found in the exterior of the root called epidermis. They are long membranous extensions from epidermal cells. They increase the surface area of the root thereby maximizing its absorption of water and minerals.
Light is the energy source for plant photosynthesis, particularly sunlight.
Chlorophyll is contained in organelles called chloroplasts.
A by-product of photosynthesis is oxygen.
A compound microscope has an application in colleges and schools. It exhibits two lenses, the ocular lens, and the objective lens. The compound microscope generally possesses more than one magnification power, varying from 40 times up to 400 or even 1000 times the original size of the specimen.
It is also used to observe tissue samples, micro-organisms, blood, microscopic cells, and some of the bigger details inside the cells. A transmission electron microscope exhibits the similar basic guidelines as the light microscope, however, the microscope rather than using light, it utilizes electrons.
These microscopes utilize electrons as a source of light. Due to the formation of low wavelength, it is feasible to obtain a resolution better than with a light microscope.
Answer:
B. The light waves get "stretched out" as they travel.
C. The light waves appear redder than expected.
Explanation:
You might hear about doppler effect before. An ambulance siren will be heard differently when it coming to you and when it moves away. When moving away, the frequency of the sound will seem to keep getting lower to the observer. A lower frequency means the sound appear to have a longer wavelength.
When scientist examines the lightwave from the distant stars, they find that the light wavelength seems stretched out and then it should be. The light also seems redder than expected. Redder light means the wavelength is longer, so the object should move away from our observation point.
Estuary is a partly enclosed coastal body of water by which river water is mixed with seawater. In a broad sense, the estuarine setting<span> is defined by
salinity boundaries instead of geographic boundaries. The word estuary is derived
from the Latin words aestus (“the tide”)
and aestuo (“boil”), signifying
the effect produced when tidal flow and river flow meet.</span>

Mitosis
Definition of Mitosis: <span>The process where a </span>single cell<span> divides resulting in generally two identical </span>cells<span>, each containing the same number of </span>chromosomes<span> and genetic content as that of the original </span>cell<span>.</span>
