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 1
Answer:

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.

sensory neuron

Sensory neurons are the neurons responsible for receiving the information from the environment or the stimuli. This sensory neurons pass the message thru interneurons and then to Central Nervous System (brain and spinal cord) which then sends the signal to the motor neuron. 

An experiment was carried out to determine whether drinking caffeinated soda increases pulse rate. The pulse rates of 30 year old men and women who were at rest were measured. On day one, each person was given a caffeinated soda. On day two, each person was given caffeine-free soda. One hour after drinking the soda, their pulse rates were measured. The participants in the experiment were all the same age and they were all given the same amount of soda. The dependent variable in this experiment is the (HINT: ______ depends on ______).

Answers

Final answer:

In the experiment, the dependent variable is the pulse rate of the participants, which is expected to change based on the intake of caffeinated or caffeine-free soda.

Explanation:

In this experiment, the dependent variable is the pulse rate of the participants. This is what the researchers are measuring and observing, and it is expected to change in reaction to the manipulated variables (or independent variables).

In this case, the independent variable is the type of soda consumed: caffeinated and caffeine-free. The hypothesis being tested is that the intake of caffeine (via soda) leads to a higher pulse rate. Therefore, the pulse rate 'depends' on whether or not the soda consumed contained caffeine.

A mutation causes a tomato plant to have much fewer, smaller leaves. Plants use their leaves to make food. Which best describes this mutation? It is harmful because it obviously affects the plant’s ability to survive. It is beneficial because it affects the plant’s physical appearance. It is neutral because it does not obviously affect the plant’s ability to survive. It is neutral because it affects the plant’s physical appearance.

Answers

Answer:

  • It is harmful because it obviously affects the plant’s ability to survive

Explanation:

Mutations are alterations in the genetic code that may occur due to environmental or chemical mutagens. Mutagens, are substances or agents that induce changes in the genetic code.

Photosynthesis is a complex biochemical process; plants convert solar energy into chemical energy as sugars like the polysaccharide glucose. They also use inorganic carbon from CO_{2 along with H_(2)O.

Plants photosynthesize in their leaves- these organs contain tissues for  CO_{2 intake, along with the chloroplasts and mitochondria, the sites of photosynthesis and respiration. If the number of leaves are reduced, this reduces the amount of tissue capable of carrying out this essential process, limiting the plant's chance for meeting its energetic needs, and thus survival.

What is an example of people changing the way water flows? *

Answers

Answer:

waterway has its own particular characteristics related to water flow, velocity, and quantity.

Altered water ways or hydrology defines the variation in such characteristics including water flow. Water flow naturally depends on the climate and landscape ( valleys, mountains and flood plains).

There are several examples of people changing the way water flows such as construction of a dam or weir and the addition of a culvert or pipe. Dams are use to control the flow of water and  through culvert or pipe, the flow or direction can be changed.

Changes in vegetation and landscape by people also affects the flow of water as well.
