Answer:
True
Explanation:
This is essentially natural selection. If there is a population of giraffes and half of them have long necks and the other half have short necks, the ones with long necks will be more likely to survive because they will be able to reach more leaves on tall trees. This means the ones with short necks will be less likely to survive, so when the long neck giraffes reproduce, they will pass on the gene for a long neck to their offspring. Over time, there will be more and more long neck giraffes and fewer short neck ones.
This is just a silly example but it is actually have animals have evolved over thousands of years lol
Answer:
Enzymes like DNA polymerase III, HELICASE, Primase, Topoisomerase, ligase.
Explanation:
DNA replication is an important process that must occur prior to cell division. DNA content of a cell becomes duplicated in the process. This process, however, cannot occur without some vital elements that play specific roles. These elements are mostly enzymes which includes DNA polymerase III, HELICASE, Primase, Topoisomerase, ligase.
DNA POLYMERASE III is the main enzyme in this process, it adds nucleotides that are complementary to the unwinded DNA strand in order to synthesize its replica.
However, a new complementary DNA strand cannot be synthesized if the original double-stranded DNA does not unwind or separate. This process of unzipping the DNA into a Y-shaped replication fork is done by HELICASE.
DNA polymerase III starts adding nucleotides from the 3' end of the DNA strand. In order to recognize this end on the strand about to be synthesized, PRIMASE synthesizes a short strand of nucleic acid called Primer. This primer provides the DNA polymerase with something to start working on.
TOPOISOMERASE works on the double-stranded DNA prior to formation of replication fork by helicase. It helps prevent the DNA strands from becoming too tight and super coiled in order to make unzipping easy.
LIGASE helps to fill up those gaps in the DNA fragments during the synthesis of a complementary strand.
Evaporation is the process that allows water to enter into the atmosphere. Sunlight turns liquid water into water vapor which then rises higher into the atmosphere and forms into clouds.
Answer:
plants need protein for healthy growth and development. One of the critical roles of protein in plants is regulating phototropism and mediating the response of plants to light-dark cycles. Proteins are also involved in energy-generating reactions, intracellular structure and membrane transport.

Answer:
In turn, the brain tells your body how to stay balanced. If you're on a rollercoaster or a boat that's moving up and down, the fluid in your inner ears might take a while to stop moving. This is why you may feel dizzy for a little while even when you stop moving or are on solid ground. Dizziness caused by the inner ear may feel like a whirling or spinning sensation (vertigo), unsteadiness or lightheadedness and it may be constant or intermittent. It may be aggravated by certain head motions or sudden positional changes.
Explanation:
How do you fix dizziness in the inner ear?
1) Sit on the edge of your bed. Turn your head 45 degrees to the right.
2)Quickly lie down on your left side. Stay there for 30 seconds.
3)Quickly move to lie down on the opposite end of your bed. ...
4) Return slowly to sitting and wait a few minutes.
5) Reverse these moves for the right ear.
