Answer: 2. The rubbish is separated first by hand, then through flotation (separating plastic and paper), magnets, and an eddy current method, which pings off aluminium and other metals. A laser beam identifies each type of plastic as it passes on a conveyor belt, then a timed jet of air pushes it into the appropriate bin. There are two broad types of recycling operations: internal and external. Internal recycling is the reuse in a manufacturing process of materials that are a waste product of that process. Internal recycling is common in the metals industry, for example. 3. Repurpose Glass, Plastic and Cardboard Containers. One of the best uses for empty plastic soda bottles is as a planter for flowers and herbs. ...

Explanation:

  1. In mechanical digestion, the teeth grind food and break it in to smaller parts.
  2. Churning and the enzyme pepsin break down protein in the stomach.
  3. The pancreas releases the enzymes trypsin and chymotrypsin.
  4. Trypsin and chymotrypsin act on the proteins to break them down in the duodenum.
  5. Amino acids are absorbed by the capillaries in the jejunum.
  6. Amino acids enter the bloodstream and are circulated throughout the body.

Further Explanation:

Food is chemically and mechanically broken down into into smaller particles. This begins in the mouth, where food is mechanically crushed by the teeth, and mixed with saliva to allow water based enzymes like lingual lipase to work;- it's then transported to the stomach via the esophagus. Next in the stomach the enzyme gastric lipase acts on lipids, breaking them up into their components.

In the stomach, the enzyme pepsin breaks proteins, like those found in salmon, into smaller peptides by splitting the peptide bonds holding the proteins together. In the stomach, the enzyme pepsin breaks proteins, into smaller peptides by splitting the peptide bonds holding the proteins together.

The duodenum processes these newly-formed peptide chains or polypeptides, into smaller ones, through the enzyme action of elastase, trypsin and chymotrypsin; these are produced in the pancreas. Peptidases convert these fragments into amino acids for absorption into the bloodstream via the small intestines.

After digestion, the process of absorption occurs within villi of the small intestine; this occurs within the jejenum. Villi are small finger-like projections from epithelial cells of the small intestine; due to the projections, they have increased surface areas for absorption. Absorption involves several processes such as:

  • endocytosis
  • passive diffusion
  • facilitated diffusion
  • active transport
  • secondary active transport (co transport)

The nutrients are then taken up into the bloodstream via capillaries, and circulated through the body

Which of the following best describes gene flow?
Dimas [21]

I have no straight answer with ABDE as of your lack there-of. But here.

Gene flow is the introduction of genes/alleles between populations. An example is a flower having it´s pollen carried by a bee. The bee then introduces it (intentional or not.) to other flowers.

Another example is a pack of gray wolves suddenly having a different wolf introduced. *As long as it can breed, that is* They will slowly incorporate the new alleles/genes into the pack.

I wish you luck young lad.

It is expected that one of the offspings might be lavender as lavender is also a type of violet color, only lighter because of the white color parent. Offsprings have genes that are obtained from the mother and father gametes which hybrid sometimes to form separate genes.
