Answers

Answer:

The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity

Explanation:

The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.

Answers

Answer:

Observable

Explanation:

An observable phenomenon leads to an hypothesis.

Answer:

2. observable

Explanation:

The scientific method relies on a scientist being able to study an occurrence and understand it. So, all the occurrences must be observable; otherwise, they cannot be studied. If the patterns are observable then one can follow the scientific method and experiment with the different variables. All science depends on the observable world and the people that study it.

Answers

Answer:

Explanation:

The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In vertebrates, the hypothalamus is the neural control center for all endocrine systems. In humans, the major endocrine glands are the thyroid gland and the adrenal glands. The study of the endocrine system and its disorders is known as endocrinology.

should their shapes be shaded? explain your answer to both questions.

Answers

Answer:

The genotype of all children in generation III is Hh. as H comes from dad and h comes from the mother for every case.

yes, their figures should be shaded.

reason :-

The dominant allele Fort this disease is shown by H whereas the recessive trait shown by h.

each offspring in generation III has the genotype Hh

and the presence of one dominant allele is enough to cause the disease.

all children in generation 3 suffer from the disease and so their figures should be shaded

Answers

Answer:

I believe the correct answer is nucleus.

Neither endosomes nor lysosomes are found in the nucleus. The nucleus serves as the primary remote control for the cell. It acts as the cell's brain by giving instructions on what to do, how to grow, and when to reproduce.

What is the cell controlling power of nucleus?

The nucleus serves as the primary remote control for the cell. It acts as the cell's brain by giving instructions on what to do, how to grow, and when to reproduce. The nucleus of the cell contains the cell's genes.

The nucleus is the area of the cell that manages all of its operations. The nucleus is a membrane-bound, spherical organelle.

Its membrane, known as the nuclear membrane, has nuclear pores that control how materials are transported into and out of the cell. The nucleus' ability to store DNA is its primary role.

Therefore, Nucleus organelle in the table is correctly matched with its function.

Answers

Answer:

Cell

Explanation:

Sodium and potassium ions are essential for muscle contractions of the heart, and the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.

What is muscle contraction?

Sodium and potassium ions play a crucial role in muscle contractions, including those of the heart, and to maintain the appropriate concentration of these ions inside and outside the cell, the body uses a protein pump called the sodium-potassium pump, which is an active pump. It requires energy to move substances across cell membranes; the pump uses the energy released by the breakdown of ATP molecules to change its shape, transport the sodium and potassium ions across the membrane, and regulate the muscle contraction.

Hence, the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.

By the end of this lab, you will see how some materials diffuse through a semipermeable membrane but others do not. The materials that you examine will differ in molecule size . Some will be larger and some smaller . Formulate an investigative question for this situation .

Answers

Answer:

Due to their sizes.

Explanation:

Some materials diffuse through a semipermeable membrane because of their small size which can pass through small pores present in the semipermeable membrane of the cell while on the other hand, some molecules can't diffuse through semipermeable membrane of the cell due to its large size. Glucose, oxygen and sodium are the examples which are smaller in size and can diffuse through semipermeable membrane whereas fats, carbohydrates and proteins are big in size so it can diffuse through semipermeable membrane of the cell.

If the PH or the temperate where the enzyme is located changes, the enzyme is very likely to
denature (become inactive/ stop working)
True
False

Answers

Answer:

very true

Explanation:

they dont like change:)

Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies.

If the PH or the temperate where the enzyme is located changes, the enzyme is very likely to denature is a true statement.

What are enzymes?

The enzymes show the best activity at optimum temperature and pH. When there is a change in the temperature, the structure of the enzyme is changed.Any change in the temperature or pH will result in the breaking of the peptides or disulfide bonds. This will disturb the tertiary structure of the enzyme. At the lower temperature, the enzymes get deactivated while, at a higher temperature, it gets denatured.

Thus, we can conclude that the correct option is True.
