Julie has been working in the laboratory with a new antibiotic. First, she placed an
antibiotic on a petri dish of bacteria. Then she placed a solution of distilled (plain)
water in the petri dish and observed under the microscope that water moves into the
bacterial cells, causing them to burst. In the control group of bacteria that did not
receive the antibiotic, the cells do not swell or burst. Julie is trying to determine what
organelle must be damaged by the antibiotic to allow for the cell to burst.

Smooth endoplasmic reticulum (SER) is an organelle found in eukaryotic cells.

the SER plays a critical role in a number of cellular processes such as lipid metabolism, detoxification of drugs and toxins, and calcium storage.

SER is abundant in cells that are specialized for the production and secretion of various substances. For example, liver cells or hepatocytes are involved in the detoxification of toxins and drugs and hence are enriched with SER.

SER contains a group of enzymes called cytochrome P450 enzymes that are responsible for breaking down and modifying drugs, hormones, and toxins. The abundant presence of SER in liver cells reflects their high metabolic activity and their role in detoxification.

The production of antibodies inside the lymphocytes starts at the ribosome (organelle) by joining amino acids together, creating peptide bonds, and forming the primary level structure polypeptide. The polypeptide bends and folds tertiary in the Golgi apparatus (organelle), to form the next level of structure. For instance, the secondary level of structure is formed by hydrogen bonds to create alpha helix or beta-pleated formations.

In order for an antibody to be released into the blood, a fully formed antibody will move from rough endoplasmic reticulum (organelle) to another organelle named Golgi apparatus to sort and be processed for shipment out of the cell. Antibodies transport from organelle to organelle and to the plasma membrane in a vesicle, which is made out of fatty acids-phospholipids.

Cell respiration involves different steps, among which there is the oxidative phosphorilation that produces and stores ATP. The answer is the electron transporter chain.

The electron transporter chain + chemiosmosis constitute the process of oxidative phosphorylation.

Chemiosmosis refers to ATP production through a proton gradient.

The electron transporter chain is a series of molecules and proteins located in the internal mitochondrial membrane.

It constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.

Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.

Different redox reactions occur to pass electrons along the chain.

Released energy creates a proton concentration gradient used to synthesize ATP.

1) NADH provides electrons to the first complex, Complex I. From there, electrons go to the coenzyme Q that carries them to complex II. Meanwhile, complex I pomp four protons to the intermembrane space.

2) Complex II receives electrons from CoQ and also receives electrons from FADH2. Electrons are sent from complex II to ubiquinone Q, which carries these electrons to complex III.

3) Complex III receives electrons from ubiquinone Q and pomps protons to the intermembrane space. Electrons are transferred to Cytochrome c.

Electrons travel from cytochrome c to complex IV.

4) Complex IV is the last complex that pomps protons to the intermembrane space.

5) Electrons are sent to O₂ molecules, which also receive protons in the matrix to create water molecules. Four electrons are needed to produce two water molecules from one O₂ molecule.

The proton gradient is used to produce ATP molecules.

In conclusion, the set of proteins in the cristae of the mitochondrion, which collectively extract the energy from reduced coenzymes to form atp, are called the electron transporter chain.

The probability of K being colorblind if he is male is equal to the probability of the mother carrying the mutant colorblind allele, which is 1/50.

Colorblindness is an X-linked recessive genetic trait, meaning it is associated with genes located on the X chromosome. In males, who have one X chromosome, the presence of the colorblind allele on that chromosome determines whether they will be colorblind or not.

The given information states that the frequency of the mutant colorblind allele in the population is 1/50, which means that in a random individual, there is a 1/50 chance of having the colorblind allele.

Since it is not known if anyone in K's family is colorblind, we assume that the mother's allele frequency is the same as the general population. Therefore, the probability of the mother carrying the mutant colorblind allele is also 1/50.

As K is male, he inherits his X chromosome from his mother. If his mother carries the mutant colorblind allele and passes it on to him, he will be colorblind. Thus, the probability of K being colorblind if he is male is equal to the probability of the mother carrying the mutant colorblind allele, which is 1/50.

Explanation:

The population after 40 years will be 400,000 animals, and the population after 65 years will be approximately 336,000 animals.

To determine the population after a certain time period, we can use the formula for exponential decay;

N(t) = N0 × \((1/2)^{(t/T)}\)

Where;

N(t) is the population at time t

N0 is the initial population

t is the time elapsed

T is the half-life of the population

Given;

N0 = 1.6 million

T = 20 years

Let's calculate the population after 40 years;

N(40) = 1.6 million × \(1/2^{(65/20)}\)

= 1.6 million × (1/2)²

= 1.6 million × (1/4)

= 400,000

Therefore, the population after 40 years will be 400,000 animals.

Now, let's calculate the population after 65 years;

N(65) = 1.6 million × \((1/2)^{(65/20)}\)

= 1.6 million × \((1/2)^{(13/4)}\)

≈ 1.6 million × 0.210

≈ 336,000

Therefore, the population after 65 years will be approximately 336,000 animals.

Answer:

1.) Dependent variable is weight

Independent variable is growth hormones.

2.) Independent variable is mosquito repellent

Dependent variable is number of bites

3.)Dependent is water

Independent is mass

4.) Indepent is the whole scenario

Dependent is the speed and how it affects the cars.

5.) Independent is the wet or dry enviroment

Dependent is the time spent

Explanation:

Dependent variable is weight and Independent variable is growth hormones.2.) Independent variable is mosquito repellent and Dependent variable is number of bites.

The dependent variable is the variable that is being measured or tested. For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants' test scores since that is what is being measured.

This is different than the independent variable in an experiment, which is a variable that stands on its own. The independent variable (tutoring) doesn't change based on other variables, but the dependent variable (test scores) may.

One way to help identify the dependent variable is to remember that it depends on the independent variable. When researchers make changes to the independent variable, they then measure any resulting changes to the dependent variable.

Therefore, Dependent variable is weight and Independent variable is growth hormones.2.) Independent variable is mosquito repellent and Dependent variable is number of bites.
