Answer: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
Explanation:
Climate change and biodiversity are two completely different things. In some areas, climate change will increase biodiversity, allowing more species to live in certain climates, but it will make some species lose their habitats. Biodiversity helps ecosystems thrive, and generally keeps things in balance. However, introducing too many species in an area can cause increase competition for food, risking predators of different species to kill one another off. Both climate change and biodiversity can be good and bad.
Answer: C. It can help some species and hurt others.
Answer:
False
Explanation:
In the troposphere, near the Earth's surface, human activities lead to ozone concentrations several times higher than the natural background level. Too much of this ground-level ozone is 'bad' as it is harmful to breathe and also damages vegetation.
The stratosphere or “good” ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays.
Answer:
No.
Explanation:
Hepatitis C is the most common bloodborne pathogen.
Hepatitis C as of 2022 has a infection rate of 3.7 million.
Hepatitis B as of 2022 has a infection rate of 2.2 million, or <em>1.5 million</em> lower than Hepatitis C.
Therefore, Hepatitis B is not the most common bloodborne pathogen.
