Answer:
THE THREE MAIN COMPONENTS OF ANY PLANT OR ANIMAL CELL ARE:
1. PLASMA MEMBRANE/ CELL MEMBRANE
Structure- a bilipid membraneous layer composed of proteins and carbohydrates. It is fluid like.
Function - the cell membrane separates the cell from its external environment, and is selectively permeable (controls what gets in and out). It protects the cell and provides stability.
Proteins are found embedded within the plasma membrane, with some extending all the way through in order to transport materials.
Carbohydrates are attached to proteins and lipids on the outer lipid layer.
Explanation:
Larger lenses are heavier, and tend to sag under their own weight, ruining the image quality as the lenses distort. The long mounting tubes are hard to make mechanically stiff, and so they tend to flex under the weight of the lens, making it hard to keep the optics in alignment.
(See figure below, where meiosis I begins with a diploid (2n = 4<span>) cell and ends with </span>two<span> haploid (n = </span>2<span>) cells.) In humans (2n = </span>46<span>), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).</span>
I think the answer is D but I’m not completely sure
