Answer and Explanation:
- Ingestion of foods and liquids
- Mechanical processing of food materials and liquids
- Warming the body with heat released from the digestive organs as they process food.
Digestion is the breakdown of food substances by enzymes to simpler compounds that can be absorbed. Digestion begins in the mouth. Once food is ingested in the mouth, it is chewed and broken into small particles suitable for swallowing. Mechanical procesing of food is through the wave-like contractions of the muscular walls of the alimentary canal called peristalsis. Churn and pound food mixing it with digestive enzymes.
After digestion, absorption and assimilation, the final product is oxidized to provide energy to the body.
D- both involve moving substances across a membrane
Reasoning:
-Active transport moves against the concentration gradient ( low to high)
-Passive transport moves higher to lower concentration
The right option is; production of gametes and hormones
The male reproductive system is a system that contains internal and external structures that are specialized to perform important functions such as production, maintenance and movement of viable sperm (the male gamete) and protective fluid (semen) for reproduction. The male reproductive system also produces and secretes male sex hormones (such as testosterone and follicle-stimulating hormone) which stimulate the activity of reproductive organs or cells.
I think the answer is glucose converted to ATP..
