The following diagram shows a system of the human body. What is the main function of this system?
Explanation:
B. to break down food so that it can be used by the body
The diagram shows the digestive system of humans system. The main function of this system is to break down food so that it can be used by the body. The correct option is B.
What is the digestive system?The digestive system is the system that starts from the mouth to the intestine of the body. It includes the esophagus, liver, intestines, and small and large intestines, pancreas, etc.
This system is responsible for breaking down food material, and this breaking down release energy. This system provides energy to the body. This system contains enzymes and acids that break the food into small forms and release energy in the bloodstream of body.
Therefore, the correct option is B. to break down food so that it can be used by the body.

What's the difference between monosomy and trisomy?
Answer:
Trisomies and monosomies are two types of chromosomal abnormalities. Specifically, a trisomy is when a person has three of a particular chromosome, instead of the usual two. A monosomy is when they just have one chromosome instead of the usual two.
For example: A trisomy is down syndrome
Explanation:
Answer:
trisomy is when a person has three of the particular chromosome rather than two. Monosomy is when someone has one chromosome rather than the usual two.
How are the various types of plants and fungi different from each other? What characteristics do plants and
fungi share?

Coal is a fossil fuel produced from plant material underground over very long geological periods of time. What are petroleum and natural gas originally formed from?
does respiration increase or decrease atmospheric carbon?
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

How would you describe dominant in a different way then this? In a easy way?
Refers to a trait that appears more frequently than another trait, resulting from interactions between gene alleles.
Answer:
A dominant allele is a variation of a gene that will produce a certain phenotype, even in the presence of other alleles. A dominant allele typically encodes for a functioning protein. The allele is dominant because one copy of the allele produces enough enzyme to supply a cell with plenty of a given product.
In a hypothetical population of 1,000 people, tests of blood-type genes show that 165 have the genotype AA, 470 have the genotype AB, and 365 have the genotype BB.

5. Explain how the discovery of Earth's true age, and the banning of leaded gasoline in the United States,
are connected?
Answer:
The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.The U.S. Congress adopted the Clean Air Act in 1970 and created the U.S. Environmental Protection Agency. Effective January 1, 1996, leaded gasoline was banned by the Clean Air Act for use in new vehicles other than aircraft, racing cars, farm equipment, and marine engines.Explanation:

Explanation:

Answer:
read below
Explanation:
specific defence systemwhite blood cells can do 3 things = they engulf the microbe, produce antitoxins, produce antibodies to neutralise microbe
> all cells carry a small protein on their surface called antigens
> every cell has a different shaped antigen
> also meaning if lets say a virus mutates its antigen will change shape
so there are 2 types of antibodies that help fight pathogens together
1) lymphocytes : recognise antigen and make a complementary antibody to fit the antigen this will neutralise the pathogen ( basically seals the whole pathogen with antibody meaning it cannot reproduce or produce toxins if bacteria) and ALSO THEY MAKE THE PATHOGEN BIND TOGETHER so that the phagocyte can kill more pathogen at once
2) phagocytes : do not produce antibodies. and they identify the antigen and ingest and destroy the pathogen 70% of white blood cells are phagocytes
fighting diseasesphagocytosis = process of phagocytes destroying pathogenantitoxins producedantibodies producedmacrophages = specialised cell involved in destruction of pathogennon specific defence systemskin
