What is the different between mechanical digestion and chemical digestion in the mouth?
Alborosie

Answer and Explanation:

The mouth is part of the digestion system.

Mechanical Digestion is the physical motion our mouth makes to chew up the food. We grind up the food with our teeth, then swallow the food into the next part of the digestive system.

Chemical Digestion in the mouth is the saliva our mouth produces. It breaks down the food along side the mechanical part of the mechanical digestion.

bearhunter [10]

Answer;

B) Neurons, epithelial cells

Explanation;

-Primary lateral sclerosis (PLS) is a rare neuromuscular disease with slowly progressive weakness in voluntary muscle movement. PLS belongs to a group of disorders known as motor neuron diseases. PLS affects the upper motor neurons (also called corticospinal neurons) in the arms, legs, and face.

-It occurs when nerve cells in the motor regions of the cerebral cortex (the thin layer of cells covering the brain which is responsible for most higher level mental functions) gradually degenerate, causing movements to be slow and effortful.  The disorder often affects the legs first, followed by the body, trunk, arms and hands, and, finally the bulbar muscles (muscles that control speech, swallowing, and chewing).

When completing Punnett Squares, you cross the letters that meet up. For example, their are two TTs and two Tts. Dominant will always show before a recessive so if it's TT or Tt it will be the dominant version. two tt's mean that it's recessive. In a Punnett Square, one box = 25%.

Part A: The genotypic ratio is 50% TT and 50% Tt. The phenotypic ratio is 100% tall.

Part B: The two Tt's could produce a short plant because there is a 25% that the parents will both give t's.
