Answer and Explanation:
Image result for How did the results prove the semiconservative model of DNA
The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand. Although Meselson and Stahl did their experiments in the bacterium E.
Answer:
Explanation:
I think one of the most invasive species is perhaps the Dandelion. Who hasn't had a fit when we see them change from yellow to gray. The yellow is pretty, but the gray means it is ready to spread its seed to create more trouble.
Dandelions can be killed with herbicides, but I think you'd be as well off putting up with the dandelion. The herbicides have an unproven effect on our health.
The dandelion was introduced into the Americas in the mid 1600s and was used as food and had medical properties. Since then, because it has no common enemy in nature, it has spread the entire width of the continent. Rather amazing, I think.
<span>This is an example of convergent evolution. These animals gained these similar antler structures to be able to survive in similar environments. Convergent evolution gives organisms who are unrelated similar characteristics as they evolve. The characteristics are influenced by the organism's similar habitats and are given to them to make sure the organisms are able to adapt to survive.</span>
<span>The nervous system that controls respiration is called
autonomic because it isn't subject to voluntary control. Autonomic Nervous
System (ANS) is responsible for regulating the functions of the body's internal
organs like the heart, stomach, and intestines. It is a division of
the peripheral nervous system that acts unconsciously and it regulates
bodily functions like heart rate, digestion, and respiration. The hypothalamus
is the part of the brain that regulates the Autonomic Nervous System. Other
reflex reactions like coughing, sneezing, swallowing, and vomiting are also
part of autonomic functions that occur in the body.</span>
