what are the most common c0vId vaccine myths and how did they start? Explain your answer.
Answer:
The most common myths are:
- C0vid2019 vaccines cause autism
- C0vid2019 vaccines may modify your DNA
- C0vid2019 vaccines are unsafe
Explanation:
The most common myths associated with C0vid2019 vaccines are:
1- C0vid2019 vaccines may cause autism: In 1998, Andrew Wakefield and colleagues published a controversial study in the Lancet where they suggested that the measles, mumps, and rubella (MMR) vaccine may cause autism in some children. However, it has been showed that this study was based on erroneous statements and therefore this publication was retracted.
2- C0vid2019 vaccine may modify your DNA: it has been suggested that vaccines based on viral vectors (e.g. adenoviruses) and mRNA vaccines may modify the DNA of cells. This statement is false because these technologies cannot alter the DNA sequence. These vaccines are based on the production of an mRNA sequence that is translated into a viral protein (spike protein) which triggers an immune response
- C0vid2019 vaccines are unsafe: some people believe that C0vid2019 vaccines are unsafe because they were developed quickly. However, this statement is false because all vaccines (including C0vid2019 vaccines) need to follow rigorous safety standards to be approved by governmental agencies (i.e., they approved all clinical trials).

Describe what a sustainable ecosystem looks like with a real-life example
Answer:
The Appalachian Region in the southwestern United States, which is one of the most richly biodiverse regions in the world. Overall, cities that recycle & reuse basically exist in harmony with the surrounding environments are also considered sustainable ecosystems. A sustainable ecosystem is one where even when things are taken, nature still has enough to function and the ecosystem/area is healthy. But dealing with domestic, industrial, & agricultural waste is a growing environmental issue. That is NOT a sustainable ecosystem.

The blue cell in the cartoon would be classified as prokaryotic cell.
What are the difference between of prokaryotic cell and eukaryotic cell ?Prokaryotic cell are single celled organism, its size varies from 0.2 μm – 2.0 μm while eukaryotic cell are multi-cellular organism and its size ranges from 10 μm – 100 μm in diameter.
Cell wall is present in prokaryotes but plant cell as an eukaryotic cell have cell wall; in Prokaryotes True Nucleus is absent while in eukaryotes true nucleus is present.
In prokaryotes Ribosomes are Smaller in size having 70s type, spherical in shape while in eukaryotes ribosomes are larger in size, 80s type and linear shaped in structure.
Circular type of DNA present in prokaryotes where as in eukaryotes DNA is Linear in shape; Mitochondria is absent in prokaryotes where as it is present in eukaryotes.

Plants play a role in this cycle by completing photosynthesis:
Answer:Plants don't eat food; they have to create it for themselves. They do this through a process known as photosynthesis. Photosynthesis uses water, carbon dioxide from the air and energy from the sun or another light source to create glucose or sugar. This glucose provides the energy the plant needs in order to survive

13. If a stream or river stops flowing due to water scarcity, what disease may result from the stagnant water?
malaria
hunger
sickle cell anemia
lung cancer
If a stream or river stops flowing due to water scarcity, the disease that will be caused by the stagnant water is malaria. The correct option is A.
What is malaria?Malaria is a disease that is caused by a protist, called plasmodium. It has four species and all give malaria. It is transmitted by mosquitoes because plasmodium lives in mosquitoes.
Stagnant water is stored water in a place for a very long time. The water of a river or s stream is stopped by dams sometimes. This water is the home to many insects to lay their eggs, like, mosquitoes.
Mosquitoes lay their eggs in water bodies or stop water, so they will lay their eggs in the stagnant water. It will increase the population of mosquitoes and with the increase in mosquitoes, there will be an increase in the cases of malaria.
Thus, the correct option is A. malaria.
