a. What is the diploid number of the species shown in Figure 1?
b. What is the haploid number of the species?
Answer:
I hope this helps you
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.
This variety is abbreviated as 2n wherein n stands for the variety of chromosomes. For people, the diploid chromosome variety equation is 2n = 46 due to the fact that people have units of 23 chromosomes (22 units of autosomal or non-intercourse chromosomes and one set of chromosomes).Under everyday conditions, the haploid variety is precisely 1/2 of the entire variety of chromosomes gift withinside the organism's somatic cells. For diploid organisms, the monoploid variety and haploid variety are identical; in people, each is identical to 23.What are chromosomes?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.

Cas9 complex scans dsDNA for PAM sequence D. Cas9 unwinds dsDNA E. The programmable part of the guideRNA binds to its complementary sequence F. Cas9 cuts both strands to generate a double strand break
Answer: a, b, d, c, e, f
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.

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.

where the energy in food is stored until it is released
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.

When a filament of algae is illuminated with light that is passed through a prism, different segments of algae are exposed to different wavelengths of light. When aerobic bacteria are present, they congregate in highest concentrations in the areas illuminated by the red and blue light. These data suggest a relationship between which of the following variables?
a) Wavelength of light and rate of aerobic respiration
b) Wavelength of light and amt of heat released
c) Wavelength of light and the rate of photosynthesis
d) Carbon dioxide concentration and the rate of photosynthesis
Answer:
The correct answer is C) wavelength of light and rate of photosynthesis.
Explanation:
The given question is a famous experiment conducted by T W Engelmann which is called the action spectrum experiment. In this experiment when light passes through a prism it splits into its constituent colors splits into violet, indigo, blue, green, yellow, orange and red.
Aerobic bacteria require oxygen for their survival. The green algae produce oxygen during photosynthesis. Engelmann released aerobic bacteria to it. it is found that the bacteria accumulated at the blue and red light because photosynthesis and oxygen release were higher there. So, it establishes the relationship between the wavelength of light and photosynthesis.

You should be familiar with the drugstore antibiotic ointment Neosporin (Triple antibiotic ointment), which is often thought of as innocuous. Based on your knowledge of antibiotics from Chapter 12 describe the mode of actions of the three antibiotics found in Neosporin (neomycin, polymyxin, and bacitracin), research their side effects, and postulate on why these three antibiotics were chosen.
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.
