all organisms possess a genetic system based on what

Answers

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.

How MDMA affects the synapses in the brain

Answers

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

8. The amount of energy the producers in this energy pyramid provide the primary
consumers is 54,000 joules. From this amount, 540 joules are provided to the tertiary
consumers. Based on this model, how much of the energy was provided to secondary
consumers?

Answers

Answer:

Energy provided to secondary  consumers = 5,400

Explanation:

Given:

Primary  consumers = 54,000 joules

Tertiary  consumers = 540 joules

Find:

Energy provided to secondary  consumers

Computation:

10 % energy is transfer to next user

So,

Primary  consumers used 54,000 joules

So,

Energy provided to secondary  consumers = 54,000 × 10%

Energy provided to secondary  consumers = 5,400

Which statement describes the structure of lipids?
O composed of chains of monosaccharides
O composed of long chains of amino acids
O composed of single or double strands of nucleotides
O composed of a glycerol molecule bonded to fatty acid molecules

Answers

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.

What is the functional group in the fatty acid ?

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.

Do you playing video games after school affect a students grade

Answers

Answer:

No, exercising something you enjoy does not affect a student's grade, if it is controlled.

Explanation:

Playing a couple of hours a day (1-3 MAX) will not affect a student's grade, but excessive playing will affect their grade negatively, as the video game will stay on their mind unconciously (most of the time) which will distract the student and prevents the student from thinking straight, regarding the fact that it could cause eye damage, and increases the chances of epilepsy.

how are saturated fats different from unsaturated fats

Answers

Answer:

Saturated fats have no double bonds in their chemical structure. They are “saturated” with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature. Unsaturated fats are typically liquid at room temperature. They differ from saturated fats in that their chemical structure contains one or more double bonds. They can be further categorized as: 3  

Monounsaturated fats: This type of unsaturated fat contains only one double bond in its structure. Monounsaturated fats are typically liquid at room temperature and include canola oil and olive oil.

Polyunsaturated fats: This type of unsaturated fat contains two or more double bonds in their structure. They are liquid at room temperature. Polyunsaturated fats include safflower oil, sunflower oil, and corn oil.

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.
