True. Cellular respiration takes glucose and converts it into ATP. Photosynthesis uses light energy to make glucose.
<span>Pesticides sprayed on
plants were eaten by small animals, which were later consumed by birds of prey.
The DDT poison harmed both the adult birds and the eggs that they laid. The egg
shells became too thin to with stand the incubation period, and were often
crushed. Eggs that were not crushed during incubation often did not hatch, due
to high levels of DDT and its derivatives.<span> </span></span>
Trees produce many materials but also contribute to the environment by producing oxygen, preserving water and soil, helping air quality, and supporting wildlife. they feed millions humans every year as well.
Answer:
The correct answer is: semi-conservative.
Explanation:
DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.
DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.
DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).
DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.
