Type B blood does make antibodies against Type A. However, the production of antibodies does not guarantee immunity, and it is possible for Type B individuals to develop antibodies against their own type of blood.
Type A and Type B blood are the two major categories of human blood groups. Each type is classified based on the presence or absence of two antigens, A and B, on the surface of red blood cells. As such, it is possible for an individual to possess either type A, type B, or both antigens.
Due to the fact that the A and B antigens are distinct from each other, and the body’s immune system recognizes the difference. When exposed to the A antigen, a Type B blood group individual will produce antibodies that recognize and attach to the A antigen, thus helping to protect the body against disease.
Furthermore, it is possible for Type B individuals to develop antibodies against their own type of blood, if they have been exposed to a transfusion of Type A blood. This is known as isoimmunization and can lead to a severe reaction if the individual is exposed to the same type of blood in the future.

How does your nose filter the incoming air?
The inside of your nose is called the nasal cavity. A mucous membrane lines your nasal cavity and it helps keep your nose moist. Little hairs inside your nasal cavity help filter the air you breathe in and block dirt and dust from getting into your lungs.

Each of DNA's four kinds of bases can pair with
only one of the other DNA bases. Using the base-
pairing rules, which of the following is the correct
order of bases that would pair with the following
string of bases on a DNA molecule:
Adenine, guanine, guanine, cytosine, thymine,
adenine
O A. Cytosine, thymine, thymine, adenine,
guanine, cytosine
O B. Thymine, cytosine, cytosine, guanine,
adenine, thymine
O C. Thymine, adenine, adenine, guanine,
cytosine, thymine
O D. Guanine, adenine, adenine, thymine,
cytosine, guanine
Answer:
The correct answer is - B. Thymine, cytosine, cytosine, guanine, adenine, thymine.
Explanation:
According to the base-pairing rule, the one purine binds with a specific pyrimidine always, the purine adenine (A) only pairs with the pyrimidine thymine (T) and similarly, the purine guanine (G) only pairs with the pyrimidine cytosine (C) in DNA, and in RNA the purine adenine (A) binds with the only uracil.
Here, the bases are -
Adenine, guanine, guanine, cytosine, thymine, adenine
the string of their base pair would be:
Thymine, cytosine, cytosine, guanine, adenine, thymine.

What effect did an increasing human population have on the sustainability of a managed ebony forest?
A)The ebony forest population increased when managed, even as the human population grew. As the human population grew, forest management caused more trees to be produced.
B) The ebony forest population remained stable when managed, even as the human population grew. Forest management allowed more trees to be grown.
C) The ebony forest went extinct. As the human population grew, it was not possible to maintain the forest, even when it was managed.
The ebony forest went extinct. As the human population grew, it was not possible to maintain the forest, even when it was managed. That is option C
Forest is one of the renewable resources that needs to be conserved.
This is because the importance of forest to humans, wildlife and the soil can not be over emphasized.
Their benefits include:
They provide a protective cover for the soil against the action of wind and rain.They act as wind-breaks, reducing wind speeds and checking the erosion of the surrounding land.They provide homes for wildlife.When there is increase in human population, the chances of a conserved forest like ebonyi forest to survive is diminished.
This is so because, with the increased population there will be:
Increased demand for timber,Clearing of forest for growing crops, Setting up industries, building roads and houses.Therefore, the government may be forced to clear the forest to attend to the needs of the growing population. This can cause the ebonyi forest to go extinct.

13. List the advantages of glycolysis.
If oxygen is present...
Answer:
Although glycolysis doesn't require oxygen, the fate of the pyruvate molecules depends on whether oxygen is present. If oxygen isn't available, the pyruvate is converted to lactate, and no additional ATP is produced from this conversion. If oxygen is present, the pyruvates are transported into the mitochondrial matrix.

Think about a model that you can construct that could be used to show the difference in prokaryotic and eukaryotic cells. In 6 complete sentences(3 for each type of cell), explain the process you would use to construct the model and how you would use the model to explain the differences between prokaryotic and eukaryotic cells to your classmates.
Answer:
Prokaryotic cell-- no organelles, no membrane.
Eukaryotic cell -- Have organelles and membrane.
Explanation:
For the model of prokaryotic cell, we construct the model by removing organelles from the cell whereas in the eukaryotic cell, we add the organelles because in eukaryotic organisms, organelles are present in the cell that performs specific function. In the model of prokaryotic cell, we have to remove membrane around the nucleus whereas membrane president around the nucleus. In the prokaryotic cell, nucleus is not visible while on the other hand, in eukaryotic cell, the nucleus is visible and can be differentiate from other organelles.

explain the effects of the production of large amounts of antidiuretic hormone in the human body
Answer:
Antiuretic hormone is a hormone that performs functions related to the reabsorption of water molecules through of the kidneys and with the decrease in the amount of urine accumulated in the body. An excess of antiuretic hormone conditions a retention of water and the elimination of sodium in the urine
Explanation:
Antidiuretic hormone (ADH) participates in regulating the water balance in the body, controlling the amount of water reabsorbed by the kidneys after they have filtered waste from the blood. Excess ADH leads to increased water reabsorption in the collecting duct, with increased urinary osmolarity. If there is too much ADH, water is retained, blood volume increases and affect can lead to nausea, headaches, disorientation, lethargy and hyponatraemia (decreased sodium concentration in the blood).

A. Write two sentences explaining how carbon returns from the air to the ground.
Answer:
In the atmosphere, carbon is attached to oxygen in a gas which is called carbon dioxide and through the the process of photosynthesis, it is pulled from the air to produce food made from carbon for plant growth. And through food chains, the animals that eat plants get that carbon and so do the animals that eat those animals.
When an animal dies, their bodies as well as wood and leaves decaying brings the carbon into the ground.
