Answer:

Opioids are currently the most effective pain relieving pharmaceuticals. However, they are also rewarding and their repeated use can lead to dependence and addiction. In fact, addiction to opioid analgesics is a growing socioeconomic and health problem with potentially serious consequences documented by a rise in deaths due to overdose [1, 2]. A critical CNS locus for opioid reward is the ventral tegmental area (VTA, glossary, vide infra). Recent work indicates that there is great anatomical and pharmacological heterogeneity in VTA neurons and that there are numerous opioid

If in tobacco plants green color (C) is dominant to white (c) and we cross 2 heterozygous green tobacco plants Cc then the genotypic ratio of the offspring is 1/2 Cc, 1/4 CC and 1/4 cc.

A heterozygous individual can be defined as an individual who carries two different gene variants or alleles for a given locus, which in this case is represented by a green color (C) allele that is dominant to the white (c) allele.

In this case, the Punnet square for this genetic cross is:

      C      c

C   CC    Cc

c    Cc    cc

Therefore, with this data, we can see that the genetic cross between heterozygous individuals is able to produce a progeny with a genotypic ratio of the offspring equal to 1/2 Cc, 1/4 CC and 1/4 cc.

Answer:

The bonds which hold the nucleotides together are covalent bonds and the bonds between nitrogenous bases are hydrogen bonds.

Explanation:

I'll just put some additional info here in case you need it:

There are two types of bonds in each nucleotide: glycosidic bond: bond between a nitrogenous base and deoxyribose pentose sugar; and phospho-diester bond: bond between two deoxyribose pentose sugar molecules. Both of these bonds are covalent, meaning that the participating atoms share electrons.

The bonds between nitrogenous bases are hydrogen bonds. Hydrogen bond is an attraction between two atoms that already participate in other chemical bonds. So it is not really "a real bond" but rather electrostatic force of attraction.

Toxic shock syndrome is most frequently brought on by Staphylococcus aureus (staph). Staph is present in the skin and nostrils of about 25% of individuals and animals. Staph can produce toxins that can lead to food poisoning, but in healthy individuals, it typically does not make them sick.

Either streptococcus or staphylococcus bacteria are responsible for toxic shock syndrome (TSS). These bacteria often reside harmlessly on the skin, nose, or mouth, but if they infiltrate deeper into the body, they may emit toxins that affect organ function and tissue.

Hemolysin, exfoliative toxin, enterotoxin, leukotoxin, and toxic-shock syndrome toxin-1 are some of the toxins that S. aureus most frequently secret.

Thus, we can conclude that toxic shock syndrome is brought on by Staphylococcus aureus (staph) germs.

By diffusion and osmosis removing their wastes and supplying them with useful substances help amoebas in survive.

Human existence depends on diffusion and osmosis because they enable cells to passively absorb nutrients and expel waste. This is due to the fact that osmosis and diffusion both entail the net movement of molecules along concentration gradients and as a result, they don't need any energy input to proceed.

Amoeba is assisted in surviving by diffusion and osmosis, which remove their waste and provide them with nutrients. Osmosis and diffusion are both passive processes, meaning they don't need the energy to work.

The maximum size that a single cell may grow to is constrained by diffusion, which only works over a certain distance. Any food and waste requirements of a single-celled microbe, such as an amoeba, may be met through diffusion.

Answer:

Based on the pattern of inheritance known as sex linkage, if a male is a hemophiliac, he has two genes for this trait on the sex chromosomes in each of his diploid cells, which is the correct answer choice (B).

Explanation:

In humans, the trait for hemophilia is a recessive trait that is carried on the X chromosome. A male has only one X chromosome and one Y chromosome, while a female has two X chromosomes. This means that a male will express a recessive trait carried on the X chromosome if he inherits a copy of the mutated gene from his mother, while a female will only express the trait if she inherits a copy of the mutated gene from both of her parents.

Since a male hemophiliac inherited the mutated gene for hemophilia from his mother, he has two copies of the mutated gene, one on each of his X and Y chromosomes. This means that there are two genes for this trait on the sex chromosomes in each of his diploid cells.

The other answer choices are incorrect, as they do not accurately reflect the pattern of inheritance for sex-linked traits.

When antibodies against a disease are given to a person rather than the individual making them naturally through their immune system, passive immunity is created.

Proteins called antibodies serve as your body's defense against foreign substances. Your immune system creates antibodies, which bind to these foreign molecules and transport them out of your body. Immunoglobulin is a different term for antibody.

Air pollution can be recognized as the influence of a bad environment.

Air pollution is a condition in which the air contains harmful molecules, either caused by human activities or due to natural occurrences from the Earth. The main cause of air pollution today is the burning of fossil fuels, such as oil and coal. Combustion of these fuels is usually used to produce energy for electricity generation or transportation.

Poor environmental conditions due to the many activities that use fossil fuels in motorized vehicles or industrial factories around us, are the main cause of air pollution. The content of carbon dioxide from fossil fuels traps heat in the atmosphere which will result in poor air quality. Air pollution will affect a person's quality of life by having a different adverse impact on each person depending on each person's immunity.

The causing difference in the two shapes is a standard explanation.

For bent vs linear, linear is a straight line with bond angles of 180 degrees. This only occurs when there are no lone pairs to cause repulsion. When there are lone pairs, then the molecule will be bent because the lone pairs cause the bonded elements to move away from the electrons.

Bent = Linear but bent due to the Lone Pairs that it contains, the more Lone Pairs the greater the bent and the smaller the degree.

If you have a lone pair of electrons you know the molecule is bent. In the case of water, there are two bonds connecting to H, but there are also two lone pairs pushing the two bonds, creating a bent shape rather than a straight line.

A byproduct of combustion called carbon monoxide functions as a chemical asphyxiant by keeping oxygen out of the blood, which causes hypoxia in the tissues and the brain.

Uncompleted fuel combustion produces carbon monoxide (CO), an odourless, colourless gas. People exposed to CO gas will become ill because the CO molecules in their bodies will replace the oxygen.

Our senses cannot perceive CO because it lacks odour, colour, or taste. As a result, dangerous gas concentrations can accumulate indoors without people noticing until they become ill. Additionally, when someone is sick, they may mistake their symptoms for those of the flu, leading them to miss the early indications of CO poisoning.

Early deletion of nucleotides in the coding sequence of a gene can result in missense mutation, frameshift mutation, multiple missense mutation and non-functional protein.

A mutation is a change in a short portion of a gene's nucleotide sequence. One nucleotide is frequently replaced by another in point mutations; other changes involve the insertion or deletion of one or more nucleotides. Large deletions can eliminate a whole gene or a number of nearby genes, whereas small deletions just remove one or a few nucleotides from a gene. The impacted protein or proteins' functionality may change as a result of the removed DNA. A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in non multiplier numbers of three. This is important because when a cell makes a protein it reads the code for the gene in groups of three bases. A missense variant is a type of substitution in which a nucleotide change replaces one protein building block (amino acid) with another in the protein made from the gene. An amino acid change can alter the function of a protein. Another type of substitution is nonsense transformation. However, instead of a change in one amino acid, the altered DNA sequence results in a stop signal that tells the cell in advance to stop making the protein.
