Answer:

relaxed packaging of the chromatin and increased transcription.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.

Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.

Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

Answer:

An outbreak of a disease that infects squirrels in the park.

Explanation:

All the other answer choices would increase the population of squirrels. For the first option, more trees = more habitats = more squirrels to live in. For the second option, less hawks = less predators = more squirrels that will survive. For the third option, heavy rain = more acorns = more food for more squirrels.

Only the last option would limit the growth of a population of squirrels since diseases kill organisms in a population.

Explanation: The steps of Cas9 DNA recognition and cleavage goes in the following order lettered A, B, D, C, E and F. Cas9 recognizes and binds the sgRNA after which it binds to the double stranded DNA. It then unwinds and scans the dsDNA for its protospacer adjacent motif sequence (PAM) and on recognition the sgRNA binds to its complementary sequence followed by cleavage of the DNA at two points. That is how the double stranded break is created.

-- b), fluorinated gas

hope this helps.

The greenhouse gas that is produced by commercial refrigeration and air conditioning systems is fluorinated gas.

A greenhouse gas is a gas that has the ability to trap and release heat energy into the atmosphere.

Greenhouse gases are the major causes of global warming, which is the rise in the global atmospheric temperature.

Examples of greenhouse gases are carbon dioxide, methane, fluorinated gas etc. Therefore, greenhouse gas that is produced by commercial refrigeration and air conditioning systems is fluorinated gas.

Explanation:

1)This number is abbreviated as 2n where n stands for the number of chromosomes. For humans, the diploid chromosome number equation is 2n = 46 because humans have two sets of 23 chromosomes (22 sets of two autosomal or non-sex chromosomes and one set of two sex chromosomes).

2)Under normal conditions, the haploid number is exactly half the total number of chromosomes present in the organism's somatic cells. For diploid organisms, the monoploid number and haploid number are equal; in humans, both are equal to 23.

The diploid number is 2n no. of chromosomes and thus it is diploid instead of haploid.

Chromosomes are thread-like systems placed in the nucleus of animal and plant cells. Each chromosome is made from protein and a single molecule of deoxyribonucleic acid (DNA).

Thus it is clear that the diploid and haploid number of the species depends on the number of chromosomes.

Answer:

The correct answer is - Mitochondria.

Explanation:

Mitochondria is the location that stores the energy in food until it is released. It is the cellular organelle that is the place where the cellular respiration process takes place.

In this organelle, the stored food is converted into a usable energy form, ATP. Mitochondria is also known as the powerhouse of the cell as it converts and releases the energy from the stored sugar or food.

Thus, the correct answer is - mitochondria.

Answer: Antibiotics are chemicals which, in low concentrations, can selectively kill or inhibit the growth of most pathogenic bacteria and are not harmful to humans.

Explanation:

Neosporin is a type of antibiotics which is used for the treatment or prevention of mild superficial infections. It consists of three active component, hence the name Triple antibiotic ointment. These active components, their mode of action and side effects include:

--> NEOMYCIN : This is one of the active components of Neosporin which inhibits the protein synthesis of an invading pathogenic bacteria through irreversible binding to the 30 S ribosomal subunit of susceptible bacteria. Their MODE OF ACTION is bactericidal meaning that the effect it has on the protein synthesis inhibits it's growth leading to the death of the bacteria.

SIDE EFFECTS: it can cause irritation, burning, itching, rash redness when applied topically.

--> POLYMYXIN: This is one of the active components of neosporin which attacks the invading pathogenic gram negative bacteria. In its mode of action, is the ability to combine with and disorganise structures of the bacterial cell which are responsible for the maintenance of the osmotic equilibrium of the cell thereby exposing the underlying peptidoglycan layer to lysozyme.

SIDE EFFECTS: Burning, redness, or irritation of the skin may occur.

--> BACITRACIN: This is also one of the active components of Neosporin. In its mode of action, it inhibits bacterial cell wall synthesis. This is achieved by preventing the final dephosphorylation step in the phospholipid carrier cycle, which interferes with the mucopeptide transfer to the growing cell wall.

SIDE EFFECTS: it may cause rash, itching/swelling (especially of the face/tongue/throat).

These three active components of Neosporin are combined to broaden the antibacterial spectrum. This means that at least one of the active components will effectively kill an invading pathogenic bacteria through its unique mode of action.

Answer:

True

Explanation:

Humidity refers to the moisture in the air or the amount of water vapor found in the air, and it is very high in rainforests is True statement.

The amount of water vapor in the air is known as humidity. The humidity will be high if there is a lot of water vapor in the atmosphere. It feels wetter outside as the humidity rises.

Relative humidity is the term typically used to describe humidity in weather reports.

The amount of water vapor that is actually present in the air, represented as a percentage of the maximum amount of water vapor that the air can contain at the same temperature, is known as relative humidity.

Therefore, Humidity refers to the moisture in the air or the amount of water vapor found in the air, and it is very high in rainforests is True statement.
