Answer 1
Answer: The advantges of organic farming compared to conventional methods of farming which are actually the most widespread types of farming are that they will release fewer pollutatns into the environment. They will also increase the biological diversity of crops and reduce the use of argicultural chmeicals. 

However, what is NOT a advantage of organic farming compared to conventional farming would be higher crop yields as conventional farming will have higher yields every season mostly due to the use of conventional agricultural chemicals.

What do bacteria have in common with the cells of other living organisms

Answers

Answer:

Bacteria and other living cells have some universal features that are, they are present in all the living cells.

These features include:

Plasma membrane: The lipid bilayer which separates the cell from the external environment. It is present in all the living organism.

Cytoplasm: It is a gel-like substance present within the plasma membrane of the cell (excluding nucleus). It contains and supports all the cell organelles and cell parts.

Ribosome: It is a vesicular structure made up of protein and ribosomal RNA. It is the main site of protein synthesis in all the cells. Prokaryotes generally contain 70S ribosomes and eukaryotes generally contain 80S ribosomes.

Genetic material: All the living organisms contains genetic material (usually DNA) either confined in the nucleus or floating freely in the cytoplasm.
They have ribosomes.They contain cytoplasm.
Some things bacteria have in common with cells of other livingorganisms is they both have chromosomes, they both have organellesand a nucleus, and are alive.

A factory is emitting large amounts of CFCs into the atmosphere. How might this affect people?

Answers

CFCs stands for Chlorofluorocarbons. These compounds have long lifetimes. Because of its long lifetimes, it will not only affect our atmosphere but will also climbed to the higher spheres of earth, particularly our stratosphere.

The stratosphere is the location of our ozone layer. It protects us from the extreme rays of the sun. Prolonged presence of CFCs in the stratosphere destroys our ozone layer. Thus, weakening the protection from the sun's uv rays. This will affect us because we are subjected to higher risk of the sun's harmful ultraviolet rays which may result to skin cancer and other sun related ailments.

Answer:

Answers

Answer:

pupils

Explanation:

When we step out into bright light, the pupil will contract, reducing the amount of light entering into the eye and protecting our retinas, as well as allowing us to see more clearly. The reason we blink and screw our eyes up in this situation is that this change in pupil size isn't instantaneous.

Answer:

Your pupils

Explanation:

When you all of the sudden go into a bright light, your pupils become smaller to adjust to the brightness. When you go back to a less dark space, your pupils will enlarge.
