Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: <u>inhaling and exhaling.</u>
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
Answer:
0
Explanation:
The parent plants are each heterozygous for round seeds and heterozygous for wrinkled seeds. Each parent contributes one allele to the offspring plant. As such, the only possible genotype of all offspring plants would be Rr (which would have round seeds as round seeds allele is dominant). Hence, no offspring can have wrinkled seeds.
Answer:
The less important allele.. ish. The allele will only "work" (Show up) if there is two recessive allele. And Ressesive allele is always lower case. So rr will show up but Rr wont because there is a dominant allele. Hope this help. :)
Explanation:
Blue Eye is recessive allele
Brown eye is dominant allele
Answer:
The correct answer would be A, Glucose, the molecule used as the energy source in cells.
Explanation:
Carbohydrates are one of some important and main sources of energy in the human body. Main sources of energy are Carbohydrates, Fats, Proteins and Vitamins and Minerals, etc. Carbohydrates are broken down in the body as glucose which are then converted into energy which is used by the cells of the body to take out many tasks of human body like growth, movements, reproduction, digestion, etc. Without energy, the body of living things cannot do routine task. So when body eats carbohydrates, they are broken down into glucose which is further transformed into energy and is used by the human body.
