The appropriate answer is c. global warming. Global warming is an increase in the global temperature caused by the increased use of fossil fuels. Using fossil fuels since the industrial revolution has pumped extra carbon dioxide in the atmosphere than what would actually enter from natural processes. This extra carbon dioxide is increasing the green house effect and causing the temperature to increase.
Answer:
The answer is:
B. Worms consuming the blood from mammals.
Algae isn't causing any harm to the sloth, rather its providing it with camouflage to hide from predators. Both creatures benefits since the algae gets to eat any parasites and other things in the sloths fur, plus they get a free ride and home in the process. The sloth isn't harmed and is helped by the algae since it provides camouflage (mutualism).
Tree frogs aren't causing harm to the trees since they are only using them to hide from predators, the tree serves as protection for the frogs and aren't harmed in the process (commensalism).
Two fish protecting each other from predators aren't harming each other in any way, rather they are protecting each other from another animal that wants to eat them (mutualism).
The worms however are harming the mammals because they are consuming the mammals blood, this is parasitism since one animal is benefiting and the other is harmed.
Hope this helps! :)
A type of lymphocyte called NK cell detects cells with abnormal surface proteins and kills them.
<h3>What are lymphocytes?</h3>
One variety of white blood cell is the lymphocyte. They are crucial to the functioning of your immune system, which aids in the body's defense against sickness and infection. An extensive network of immune cells, lymph nodes, lymph tissue, and lymphatic organs makes up your immune system. Immune cells include lymphocytes. The two primary categories of lymphocytes are:
T lymphocytes (T cells): T cells direct your body's immune response and actively hunt down and destroy cancerous and infected cells.
B cells, or B lymphocytes: The B cell produces antibodies. Proteins called antibodies hunt down viruses, bacteria, and other foreign invaders.
Your body's immune system uses lymphocytes to combat cancer and invading viruses and germs (antigens). Your immune system benefits from lymphocytes' assistance in retaining every antigen it encounters. Some lymphocytes develop into memory cells after an encounter. Memory cells detect an antigen and reactbwhen they come into contact with it again. You don't contract illnesses like measles or chickenpox repeatedly because of this. Additionally, it explains why some diseases can be avoided through vaccination.

Answer:
Carbohydrates can be described as biological molecules which are made up of carbon, hydrogen and oxygen.
Simple carbohydrates are known as monosaccharides. Example of monosaccharide includes glucose and fructose. Two molecules of monosaccharides can join to form disaccharides. Example of disaccharide includes maltose. When three or more monosaccharides join they form polymers known as polysaccharides. In this way, simple carbohydrates form larger molecules or polysaccharides. Examples of polysaccharides include starch, glycogen, cellulose etc.
