Doctors have had luck transplanting hearts and lungs. But science has not been very successful in growing hearts and lungs. Why?

A) They contain nerves and scientists cannot grow nerve cells. B) They are complex organs made of many types of cells and tissues. C) Even if researchers build a heart or lung, there is no guarantee that a person's body will accept it. D) Human hearts and lungs are not like any other animal organs so there is not source for cells and tissues.

Ans. (B). They are complex organs made of many types of cells and tissues.

Organ culture involves development of tissues or organs, in vitro (outside the body), to restore, maintain, or improve damaged organs or tissues. Many organs and tissues are successfully grown by engineered tissues, such as skin and cartilage.

However, heart, lungs, and other complex organs have not been very successfully grown as these organs are made up of different types of tissues and cells. For examples, heart is made up of cardiac muscle tissue, skeletal tissues, and smooth muscle tissue.

It is quite tough to assemble different types of cells and tissues to make organs fully functional or reproducible.

Thus, the correct answer is option (B).

Hello.

Man cannot scientifically recreate a heart or lung in a lab. It just doesn’t work that way. Therefore, your answer is B.

I hope this helps you!
Have a wonderful day.

Each red blood cell is shaped as a biconcave disk. This allows it to?
kipiarov [429]

Red blood cell is shaped as a biconcave discs, this shape allows them to squeeze through small capillaries.

The biconcave shape of the cell allows oxygen exchange at a constant rate over the largest possible area. The biconcave shape increases the cell's surface area compared to a flat disk of the same size. The greater surface area makes it easier for gases to move into and out of the red blood cell.

The biconcave shape provides a large surface area compared to the volume of the red blood cell, allowing diffusion to happen efficiently. This shape optimizes the ratio of surface area to volume, facilitating gas exchange. It also enables them to fold up as they move through narrow blood vessels.

krek1111 [17]

Answer:

The correct answer is ''The scientific study of heredity''

Explanation:

Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.
