how do depressants affect the central nervous system
Answer:
Depressant substances reduce arousal and stimulation. They do not necessarily make a person feel depressed. They affect the central nervous system, slowing down the messages between the brain and the body. They can affect concentration and coordination.

Which of the following properly describes an ion?
O an atom or molecule that has lost or gained one or more electrons
O a molecule that has lost or gained one or more atoms
O an atom or molecule that has lost or gained one or more protons
O an atom that has lost or gained one or more neutrons
An ion is an atom or a molecule that has lost or gained one or more electrons. So the correct option is A.
What is an ion?An atom or molecule which has a charge is referred to as an ion. Usually, the number of electrons and protons in an atom is equal. While electrons are present in the atomic shells, protons are present in the nucleus.
Because, the electrons are negatively charged and the protons are positively charged, the loss of one or more electrons would mean that the atom will now be positively charged. This will be called a positively charged ion.
Also, the gain of one electron would mean a gain of an additional negative charge. So the atom will now be negatively charged and will be called a negatively charged ion.
This is true for an atom individually or an atom which is part of a molecule. In that case loss or gain of one electron would result in the development of a positive or negative charge on the molecule.
Therefore the correct option is A.

If the DNA sequence is --- AAA TAT CCG TAG CAA ATG, write the mRNA sequence, tRNA anticodon sequence, and the six amino acids for this.
adenine(A) binds with uracil(U)
Thymine(T) binds with Adenine(A)
guanine(G) binds with cytosine(C)
The complementary mRNA, which contains the codons is
UUU AUA GGC AUC GUU UAC
The complementary tRNa , which contains the anticodons is
AAA UAU CCG UAG CAA AUG
The six aminoacids are
phenylalanine-isoleucine-glycine-isoleucine-valine-tyrosine
The bases tend to exist as a pair in the DNA’s double helix structure. The bases are bonded by hydrogen bonds.
Their bonds are mentioned as follows:
Adenosine (A) is paired with thymine (T) Cytosine (C) is paired with guanine (G)However, the base thymine (T) is present only in the nucleotide of DNA and the base uracil (U) is present only in the nucleotide of RNA.
Based on the understanding of the nucleotide and central dogma concepts, the following sequences are determined:
DNA Sequence: AAA TAT CCG TAG CAA ATGmRNA Sequence: UUU AUA GGC AUC GUU UACtRNA anticodon: AAA UAU CCG UAG CAA AUGSix amino acids: PHE ILE GLY ILE VAL TYRSix amino acids are namely Phenylalanine, Isoleucine, Glycine, Isoleucine, Valine, and Tyrosine.

Can some one give me a brief paragraph of how low pressure system can cause storms
Answer:
Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms.

Explanation:
blood enters on the left side of the heart through the_____ and enters the left atrium. Then passes through the_____ to enter the left ventricle 
Blood enters on the left side of the heart through the pulmonary veins and enters the left atrium. Then passes to the mitral(bicuspid valve) to enter the left ventricle.
Blood is a fluid component of the circulatory system that is very vital for transporting oxygen and nutrients in the body system. It comprises cells suspended in plasma.
The correct answers for the blanks are:
Blank 1: Pulmonary veinsBlank 2: Bicuspid valveThe blanks can be explained as:
The left side of the heart has an atrium that gets the oxygenated blood from the lungs through the pulmonary veins.Oxygenated blood from the left atrium flows to the left ventricle.Blood from the left ventricle flows to the aorta that distributes the oxygenated blood to the body parts.To learn more about the path of the circulatory system follow the link:

If a cell normally has 32 chromosomes, what would be the results of going through mitosis?
Answer:
For mitosis, the DNA content of the daughter cells and the mother cell will always be identical. Since the number of cells have doubled, so has the DNA. The 16 chromosomes in the mother cell will be duplicated, then the duplicates split and evenly divided into the daughter cells. The 16 chromosomes in each daughter cell will be non-duplicated at first.
