Answers
Answer:
all answer see explanation
Explanation:
1. Ans. The Breathing Muscles
. When you inhale, the diaphragm and muscles between your ribs contract, creating a negative pressure—or vacuum—inside your chest cavity. The negative pressure draws the air that you breathe into your lungs.
2. Ans. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”
3.ans. Secondary immune response is more intense than the primary immune response because our body appears to have memory of the first encounter that recognize the pathogen quickly on subsequent exposure and overwhelm the invaders with a massive production of antibodies.
4. Ans. Lipid digestion and absorption pose some special challenges. Triglycerides are large molecules, and unlike carbohydrates and proteins, they’re not water-soluble. Because of this, they like to cluster together in large droplets when they’re in a watery environment like the digestive tract. The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases. The mouth and stomach play a small role in this process, but most enzymatic digestion of lipids happens in the small intestine. From there, the products of lipid digestion are absorbed into circulation and transported around the body, which again requires some special handling since lipids are not water-soluble and do not mix with the watery blood
5. Ans. ..Due to their parasitic mode of life these worms completely lost their digestive apparatus but have a well-developed reproductive system and special organs that help them attach to the host's tissues. They also needed a mechanism to protect themselves from intestinal substances, specifically digestive enzymesfrom
Explanation:
paristic worms can not be digested by human digestive system because simply they are parasites ans why does parasite needed to be digest ...so its better for humans to eat things which are humanity based not like chinese poeple...lol...
