Which word belongs in a different group than the group below?brain, glands, motor neuron, movement, muscles, sensory neuron, stimuli

brain
motor neuron
glands
stimuli

Answers

Answer:

In the group of a brain, motor neuron, glands, and stimuli, the glands can be considered as an odd one out.

It is because the brain, motor neuron, and stimuli come under a common biological system which is termed as a nervous system.

A nervous system is a network or complex of nerve cells that perform the function of transmitting nerve impulses from one body part to another.

It consists of a brain, spinal cord, and different types of nerve cells (such as sensory nerves, motor nerves et cetera).

In contrast, a gland is defined as an organ of cells which synthesize and release chemical substances (such as hormones, enzymes et cetera) either into the bloodstream (endocrine glands) or into the body cavities (exocrine gland).

Thus, the gland can be considered as the odd one out.

9. Which of the following best sequences the functions of the digestive system from start to finish? A. Absorption, ingestion, digestion, elimination B. Ingestion, digestion, absorption, elimination C. Elimination, absorption, ingestion, digestion D. Ingestion, absorption, digestion, elimination

Answers

Answer:

The correct answer would be B. Ingestion, digestion, absorption, elimination.

Digestion refers to the breakdown of complex compounds into simpler elements.

The process of the digestive system can be sequenced as:

  1. Ingestion: Intake of food from outside the body. For example, in humans, food is taken in from a mouth.
  2. Digestion: The breakdown of complex compounds into simpler elements. For example, polysaccharides, polypeptides, and fats are converted into monosaccharides, amino acids, and fatty acid chains and glycerol respectively.
  3. Absorption: The digested food is absorbed and transported to all parts of the body. In humans, the small intestine is the major site of food absorption.
  4. Assimilation: The nutrients are transported or distributed to all cells of the body where they are utilized for power generation.
  5. Excretion: The undigested food is then excreted out of the body. In humans, the solid waste is excreted through the anus.
its B.
 you eat it (ingest) it goes to your stomach (digest) then to your intestines where more nutrients are extracted(absorption) then to your and out your anus (elimination) 

Arial decides to ride her bike to work instead of driving her car. What impact is this decision likely to have on the environment? A. More energy resources will be required. B. Contamination of nearby land will be reduced. C. The global footprint of people in the US will increase. D. Less carbon dioxide will be released into the atmosphere.

Answers

D.

Since she's not driving her car, there is no carbon emissions emitting from her car. Thus, there will be less carbon dioxide in the atmosphere in comparison if she were to drive her car. Good luck!
I go for D since riding a bike will not produce smoke to the atmosphere and is more environmental friendly.
