3.Spirometry measures how much air you can breathe in and out. It also measures how fast you can empty the air out of your lungs. Spirometry helps diagnose breathing problems such as asthma and COPD.

4. Tar causes cancer of the lungs, mouth and throat.

Q1) Of the more than 7,000 chemicals in tobacco smoke, at least 250 are known to be harmful, including hydrogen cyanide, carbon monoxide, and ammonia (1, 2, 5). Among the 250 known harmful chemicals in tobacco smoke, at least 69 can cause cancer.

Q2) The function of cilia is to move water relative to the cell in a regular movement of the cilia. This process can either result in the cell moving through the water, typical for many single-celled organisms, or in moving water and its contents across the surface of the cell.

Q3) Lung volume measurement can be done in two ways:
The most accurate way is called body plethysmography. You sit in a clear airtight box that looks like a phone booth. ...
Lung volume can also be measured when you breathe nitrogen or helium gas through a tube for a certain period of time.

Q4) Tar contains most of the cancer-causing and other harmful chemicals found in tobacco smoke. When tobacco smoke is inhaled, the tar can form a sticky layer on the inside of the lungs. This damages the lungs and may lead to lung cancer, emphysema, or other lung problems.

Differentiate between parental and recombinant gametes.
Eddi Din [679]

Answer: The two types of gametes are possible for when they are following genes that are on the same chromosomes. If they are crossing over, it does not occur, the products are known as Parental Gametes. If they are crossing over, the products are Recombinant Gametes. It is usually the simple matter that determine which of these gametes are recombinant gametes.

The difference between these two genes, is that are far apart and the frequency of recombination of genes is fifty percent. These genes that are closely located on the chromosome exhibit only have a few cross overs. The gametes that have recombined chromosomes, are known as Recombinant Gametes while the Parent Gametes are carrying on non-recombinant chromosomes.

I hope this helps you!

zalisa [80]

Answer:

Explanation:

The primates have a hand feature which increases their fitness in the tree environment are the opposable thumbs. The thumbs are the broadest digit of the hand. The thumb can move in different directions in comparison to the other digits of the hand. This is an advantage in primates to hold and grasp the objects with their hands.

The monkeys climbing on the trees grasp the branches of trees to move from one tree to another.
