Observation and measurements recorded during an experiment. All the variables that are kept the same throughout the experiment so they will not affect the results of the experiment. independent Variable. The variable which the experimenter changes so that he/she can observe the results of the experiment.

The statement which says that it is   composed of a glycerol molecule bonded to fatty acid molecules, it is the glycerol molecule which holds up together the fatty acid molecules. The statement that is correct is option D.

Fatty acid is the bio molecule in which the functional group is the carboxylic acid.

In molecule of the fats, the molecules of the  fatty acids are linked to each of three of the  carbons of  the glycerol molecule with the ester bonds  through oxygen atoms. While ester bond is forming on, 3 molecules are  being released. Since the  fats are  consisted  of three fatty acids with the  glycerol but  they are called as  triacyl glycerol  as well or the  triglycerides.

A glycerol with the  3 fatty acids are  attached with are  referred  as triglyceride , that is a sub constituent of  the lipids or fat.  It is formed from  molecules  of  the glycerol with 3 fatty acids.  The molecules of the triglycerides are main energy storing molecules of  body of  the animals that is  mainly stored inside the  adipose tissue.

Explanation:

Observations

Answer:

MDMA affects the brain by increasing the activity of at least three neurotransmitters (the chemical messengers of brain cells): serotonin,89,90 dopamine, and norepinephrine.91 Like other amphetamines, MDMA enhances release of these neurotransmitters89–92 and/or blocks their reuptake,93,94 resulting in increased neurotransmitter levels within the synaptic cleft (the space between the neurons at a synapse).

Answer:

MDMA increases levels of these neurotransmitters within the synapse

Answer:

DNA

Explanation:

Deoxyribonucleic acid or DNA is defined as the genetic material in all the living organisms responsible for all the genetic activities in an organism.

DNA carries genetic instructions that are inherited from one generation to another generation. The DNA comprises of genes having specific genetic code that encodes the sequence of amino acid residues in proteins. DNA undergoes the process of replication and form several copies of it which are passed on to next generation.

Hence, the correct answer is "DNA".

All organisms possess a genetic system based on DNA as it is a hereditary material.

DNA  is a hereditary material which is present in human beings as well as all other living organisms.  Every cell which is present in an organism's body has DNA  which is the same. Most of the DNA is situated in the cell's nucleus  and small amount of it can be found in the cell's mitochondria as well.

Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.

As all genetic information is stored in DNA all genetic systems are based on DNA.

Answer:

This question is incomplete; the complete question is as follows:

Pillbugs are placed in a container where they have a choice of a wet or a dry environment. Researchers record how much time was spent on each side. What is the INDEPENDENT and DEPENDENT variables?

The independent variable is WET OR DRY ENVIRONMENT

The dependent variable is TIME SPENT

Explanation:

The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to bring about an effect on the dependent variable.

Conversely, the dependent variable is the variable that the experimenter measures in an experiment. It is dependent on the independent variable.

In this question, the researchers placed pillbugs in containers that are either WET or DRY in order to measure how much time they spent in each side. Hence, the independent variable is the WET or DRY environment the pillbugs were placed because it is what the researcher changes while the dependent variable is the TIME SPENT because it is what the researchers measure.

Answer:

The answer is D.

Explanation:

I think the answer to this question is D because the employees are constantly exposed to poisonous chemicals. The Chemical Hygiene Plan (CHP) states " CHP is a written program stating the policies, procedures and responsibilities that protect workers from the health hazards associated with the hazardous chemicals used in that particular workplace."

Hope this helps!

Robert, who owns a fertilizer manufacturing firm have made some findings and these can be documented and referred as Chemical Hygiene Plan (CHP). Thus, the correct option is D.

The Chemical Hygiene Plan (CHP) is a written program which states the policies, procedures, and responsibilities which protect the workers from the health hazards which are associated with the hazardous chemicals that are used in that particular workplace.

Chemical Hygiene Plan includes list of several things which are hazard identification strategies, hazard controls, equipment inspection and maintenance protocols, employee training requirements, medical consultation and examination, containment equipment, and the procedures which require prior approval.

Explanation:

The secretory pathway moves proteins to the cell membrane, where they are released to the extracellular medium. In this pathway, the proteins enter into the membrane of the rough Endoplasmic Reticulum (ER) in a cotranslationally way (i.e., during their synthesis in ribosomes). This pathway can be summarized by the following transporter activities: Endoplasmic Reticulum >> Golgi apparatus >> secretory vesicles (such as lysosomes) >> cell membrane, where proteins are finally released by exocytosis.
