Draw the phases of mitosis of a cell that contains four chromosomes as its diploid or 2n number

Answer:

Monomer is a molecule that can be bonded to other identical molecules to form a polymer.

Polymer is a substance which has a molecular structure built up chiefly or completely from a large number of similar units bonded together

A monomer is a molecule that forms the basic unit for polymers, which are the building blocks of proteins

Polymer is a big molecule that forms from monomers, it consist of macromolecules (large molecules)

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:

Independent variable- different kind of music played

Dependent variable- will listening to music make the players make more baskets?

Control- didnt play any music at all

Explanation:

CJ wanted to see if listening to music would make the basketball players make more baskets. Day 1, he didn't play any music and counted how many baskets they could make in 10 minutes. Day 2, he played rap music and counted the baskets. Day 3, he played classical music and counted the baskets.

The Independent variable in above question is listing to music or not because it totally depend upon CJ that he is listing music or not.

Dependent variable

The dependent variable in above question is number of basket made by the players because it's totally depend on player that how much he want to made basket.

Controlled variable

The controlled variable in above question is 10 minute time period, players, height of the basket because it totally depend upon CJ that how much time they listen music and how he throw the basket so all above is controlled variable.

Therefore,CJ wanted to see if listening to music would make the basketball players make more baskets. Day 1, he didn't play any music and counted how many baskets they could make in 10 minutes. Day 2, he played rap music and counted the baskets. Day 3, he played classical music and counted the baskets.

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

The mitochondrial DNA team examines biological items of evidence from crime scenes to determine the mitochondrial DNA (mtDNA) sequence from samples such as hair, bones, and teeth. Typically, these items contain low concentrations of degraded DNA, making them unsuitable for nuclear DNA examinations.

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.

Answer:

The receptors on the postsynaptic membrane (dendrites) of a neuron receive(s) the transmitter released by other neurons.

Explanation:      

Neurons transmit nervous impulses. These cells are formed in general by a cellular body, dendrites and an axon. The dendrites are cytoplasmic extensions that receive stimuli from other cells. The axon is a long formation capable of conducting the electrochemical signals.    

Every neuron forms connections with other neurons. These connections are known as synapsis. As it happens in every synapsis between neurons when a presynaptic neuron sends information, a neurotransmitter is released. This molecule is a chemical substance that travels through the synaptic cleft to the junctional area of the other neuron and binds to its receptors in the postsynaptic membrane, located in dendrites of the other neuron. This receptor is a protein structure that triggers an answer. The binding produces a depolarization of the cell called an excitatory postsynaptic potential. An action potential is initiated and spreads to the rest of the membrane depolarizing it.  As long as the signal molecule is in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space.

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.

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.
