Answer:

The correct answer is - True.

Explanation:

Degradative pathways are the pathways that provide energy for the anabolic reactions, these are catabolic reaction. An activator protein is a protein that enhance the transcription by binding to DNA.

A transcriptional activator are bind to the enhancers or promoter proximal elements. These are the the DNA binding proteins that regulates the transcription of the DNA molecule.

Thus, the correct answer is - true.

Number the steps from when the stimulus received to when the body reacts​
Natasha2012 [34]

The given question is not complete. The complete question is:

Number the steps from when a stimulus is received to when the body reacts.

The stimulus is received by sensory receptors.

Motor neurons cause muscles to contract so the body can react to the stimulus.

The brain processes the information through interneurons.

Interneurons transfer response information to motor neurons.

Sensory neurons carry stimulus information to the brain or spinal cord.

Answer:

The body of an organism like humans reacts towards each of the external stimuli of the environment like the smell of the food and even to the internal stimulus like hunger or pain. Thus, it can be considered that one is stimulated all the time and reacts towards the constituents found in the surroundings. The entire procedure of the organism reacting towards the stimuli are as follows:  

1. The sensory receptors receive the stimulus.  

2. The stimulus information is further carried to the spinal cord or the brain by the sensory neurons.  

3. The processing of the information in the brain takes place with the assistance of interneurons.  

4. After that the response information is mediated towards the motor neurons by the interneurons.  

5. The motor neurons eventually result in the contraction of muscles showing that the body is reacting towards the stimulus.

Which value is being measured in the columns labeled fraction remaining and percentage remaining
ahrayia [7]

<u>Question</u>:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

  1. years of decay
  2. quantity of energy
  3. number of stable atoms
  4. amount of material that has not decayed

<u>Answer</u>:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

<u>Explanation</u>:

The table shown below having explains about the half life , the  amount of sample in both fraction and percentage. The first column named half life elapsed tells  us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind  after the half life particular number of half life has completed.  similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over \frac{1}{16} th of the sample remained. In percentage it is 6.25%
