Answer:
20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.
Majority of energy, around 90% in fact, is lost between each trophic level, mostly due to the energy usage of sustaining life, and a lot is lost as thermal energy.
I think you're talking about histones. Histones are proteins found in eukayotic cell nuclei. Histones are what DNA wrap around so it fits inside the nucleus and helps with the formation of chromosomes.
Answer:
D. cytokines differs in plant cells and animal cells
Explanation:
A. is false, as prokaryotes to not divide by mitosis. They divide by binary fission.
B. is false. Animal Cells do not have cell walls. Prokaryote and Plant cells have cell walls. Animal Cells have plasma membranes.
C. is also false. Eukaryotes have line-like chromosomes. Prokaryotes have a single circular chromosome.
D. IS true. Cytokinesis differs in plant cells from animal cells. This is mainly due to the cell wall in the plant cell.
<span>There are many types of algae. Some of which are brown algae or the Phaeophyta/Phaeophytes,the green algae which is also known as the Chlorophytes, and the Chrysophytes or the golden algae. Among these algae, only the Chrysophytes shows distinct alternation of generations or metagenesis.</span>
