Which organ systems help deliver oxygen to body cells

Answers

Respiratory and the circulatory.
The respiratory system allows gas exchange to occur at the lungs, swapping CO2 for O2.
This O2 is then picked up by the blood travelling through the circulatory system, allowing it to be delivered to the cells.

Final answer:

The respiratory and circulatory system work together to deliver oxygen to body cells.

Explanation:

The respiratory and circulatory systems work together to deliver oxygen to body cells. The respiratory system is responsible for breathing in oxygen and expelling carbon dioxide, while the circulatory system transports oxygen-rich blood to the cells. Within the circulatory system, the heart pumps oxygenated blood through arteries to the body's tissues, where oxygen is delivered to the cells through capillaries.

The process of ____________ increases genetic variability as it produces gametes for sexual reproduction.

Answers

The phrase to fit into the blank is "sexual reproduction"!
In sexual reproduction each of the parents produces a gamete and contributes to half of the  offspring's genes. This means that the offspring is a unique composition of the two parents.

In contrast, in a asexual reproduction, the offspring would likely have the same genetic code as the parent.

Final answer:

Meiosis increases genetic variability as it produces gametes for sexual reproduction.

Explanation:

The process of meiosis increases genetic variability as it produces gametes for sexual reproduction. Meiosis is a type of cell division that results in four daughter cells with half the number of chromosomes as the parent cell. During meiosis, genetic recombination and crossing over occur, leading to the production of genetically diverse gametes.
