A type of lymphocyte called a(n) ________ detects cells with abnormal surface proteins and kills them.
kirill [66]

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.

What was a major problem for anthropologists when they were just studying objects in museum collections?
tia_tia [17]

A major problem for anthropologists when they were just studying objects in museum collections was that the objects were viewed as isolated from their cultural context.

<h3>What is Anthropology?</h3>

Anthropology is the scientific study of humans and includes the study of historical and contemporary human species as well as human behavior, biology, cultures, civilizations, and linguistics. While cultural anthropology examines cultural meaning, including norms and values, social anthropology explores patterns of behavior.

Today, the phrase sociocultural anthropology is frequently employed as a portmanteau. Language's impact on social life is the subject of linguistic anthropology. The biological evolution of people is studied in biological or physical anthropology.

Archaeological anthropology, sometimes known as "anthropology of the past," examines physical evidence to study human behavior. In North America and Asia, it is regarded as a subfield of anthropology, but in Europe it is viewed as a field unto itself or categorized under other related fields like paleontology and history.

PLEASE HELP
kvv77 [185]
The first step I would use is to use a magnet to remove the iron filings. This is because only metal is attracted to magnets. I would then use a sieve to filter the sand and salt from the gravel. This is because the gravel will have a larger diameter than the sand and salt particles, and will stay behind while the salt and sand will pass through the sieve. Finally, I would remove the salt from the sand by placing the mixture in water. The sand will tend to sink to the bottom while the salt will dissolve into solution.

Some solar cells function by collecting electrons that are emitted from a metal or semiconductor due to sunlight shining on them
andrezito [222]

Answer:

the law of conservation of energy

Explanation:

A basic rule of physics called the law of conservation of energy says that we can't magically create energy or make it vanish into thin air; all we can do is convert it from one form to another. That means a solar cell can't produce any more electrical energy than it receives each second as light.
