ella [17]

Enzymes come from the pancreas.

What are Enzymes?

Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

The small intestine, not the stomach, is where carbohydrates are chemically broken down. The chemical breakdown of digestible carbohydrates is completed by disaccharidases and pancreatic amylase. The circulation carries the monosaccharides to the liver after absorption.

Bryophytes never formed forests (mats, yes, but not forests) because ________. a. they possess flagellated sperms.
maria [59]

Answer:

c. They lack lignified vascular tissue

Explanation:

We know that forest consists of tall trees. In the tall trees the water and minerals are transported to the every part of tree through the lignified vasucular tissue. This tissue not only helps in transport within the tree but also provides some sort of mechanical strength due to the presence of lignin it its walls. On the other hand bryophytes are non-vascular plants which means they lack vascular tissue and thus a mechanism for long distnace transport of water and minerals is absent in them. So they can't be taller as a tree and thus can't form forest.
