Answer:
A
Explanation:
Passive transport does not require energy. The substances follow the concentration gradient, meaning they go from high to low. Active transport goes against the concentration gradient. Substances go from low to high, so it requires energy.
Even though both organelles are found in eukaryotic cells<span>, both </span>mitochondria and chloroplast<span> have characteristics often found in </span>prokaryotic cells<span>. These </span>prokaryotic cell<span> characteristics include: an enclosed double membrane, circular DNA, and bacteria-</span>like<span> ribosomes.</span>
Answer:
Absorption
Explanation:
Epithelial tissue aid absorbtion, secretion, and excretion of substances. In the intestines, it aid absorbtion of nutrients during digestion.
The columnar epithelium possess pillar-like and column-like cells located in the lining of the stomach and intestine. It aid absorption and secretion.
The types of animal tissues are the Connective tissue, epithelial tissue, muscle tissue, and nervous tissue. Connectuve Tissues arises from the mesoderm. All connective tissue is made up of three major components: fibers (elastic and collagenous fibers), ground substance and cells.
Basic functions of connective tissues includes binding and supporting, protecting, insulating, storing reserve fuel, and distribution of substances within the body.

Optical Microscope - Resolution
Explanation:
Optical microscope resolution is the shortest length between any two closely located bright points on the specimen which can be viewed clearly by the viewer.
The resolution ability of an optical microscope is specified by how it distinguishes these two airy disk points which are closely placed on the specimen.
In optical microscope, with higher magnification, the image may get blurred or unsharp which can be corrected depending upon its objective. The resolution increases with increase of the numerical aperture of the entire system.
The resolution of an optical microscope is around 200 nm with a magnification power of about 1000. This resolution is less compared to that of an electron microscope
