Answer:
D.
Explanation:
Oil stays separate from water and stays at the top, so you can skim it off.
Answer:
Plants take in carbon dioxide from the environment for photosynthesis. Because trees are large, they need a lot of energy, which likely results in a lot of carbon dioxide being removed from the air. If they’re chopped down, there will be fewer trees to remove the extra carbon dioxide from the air.
Explanation:
answer from Plato
“a restriction enzyme is an enzyme that cuts DNA after recognizing a specific sequence of DNA. You can think of restriction enzymes as molecular scissors. Scientists can use restriction enzymes to cut a single gene from a larger piece of DNA. ...They evolved in bacteria” (study.com)
so, they are used to cut DNA into smaller pieces(:
Answer: The curvature of the crystalline lens increase
Explanation:
Since accommodation is the ability of the eye lens to change in shape so as to focus on an object. So, when we look at a far-away object, the ciliary muscles relaxes and moves away from the lens making the suspensory ligaments tight, pulling the lens, and causing its crystalline curvature to become thinner (decrease), so that light rays passing through it are bent less enabling them to focus on the retina.
However, the reverse happens when the human eye focus is switched to a near object, such that: ciliary muscles contracts, suspensory ligaments slackens, and crystalline lens becomes more curved (increase)
Thus, the change in accommodation makes the curvature of the crystalline lens to increase
Cells with a nucleus are called Eukaryotes. Eukaryotic cells also have membranes around the organelles. Cells without a nucleus are called Prokaryotes. Prokaryotic cells do not have membranes around their organelles.
