A disorder in which the immune system is overly sensitive is known as an autoimmune disorder or hypersensitivity disorder.

Autoimmune disorders occur when the immune system, which is designed to protect the body against harmful substances, malfunctions and targets its own cells and tissues. This abnormal immune response leads to inflammation and damage to various organs and systems.

The exact cause of autoimmune disorders is not fully understood, but a combination of genetic and environmental factors is believed to play a role. These disorders can affect different parts of the body, such as joints (rheumatoid arthritis), skin (psoriasis), or organs (lupus). Treatment often involves managing symptoms and suppressing the immune response through medication and lifestyle modifications.

(a) The probability that exactly 3 individuals have conditions caused by outside factors is 0.183. (b) The probability that 3 or more individuals have conditions caused by outside factors can be calculated using a cumulative binomial distribution table or a statistical calculator. (c) The mean number of individuals with conditions caused by outside factors is 1.8, and the standard deviation is 1.124.

To solve this problem, we can use the binomial distribution since we are dealing with a fixed number of trials (15 patients), and each patient's condition is either caused by outside factors or natural occurrences, with independent probabilities.

(a) To find the probability that exactly 3 individuals have conditions caused by outside factors, we use the binomial probability formula:

Probability = C(n, x) * p^x * q^(n-x)

where n is the total number of trials (15), x is the number of successes (3), p is the probability of success (12% or 0.12), and q is the probability of failure (88% or 0.88).

Plugging in the values, we have:

Probability = C(15, 3) * 0.12^3 * 0.88^(15-3)

Probability = 0.183

Therefore, the probability that exactly 3 individuals have conditions caused by outside factors is 0.183.

(b) To find the probability that 3 or more individuals have conditions caused by outside factors, we need to calculate the probability of 3, 4, 5, ..., 15 individuals having outside factors and sum them up.

Probability = Probability(3) + Probability(4) + ... + Probability(15)

Using the binomial probability formula, we can calculate each individual probability and sum them. However, to save time and effort, we can use a cumulative binomial distribution table or a statistical calculator.

Assuming you have access to a statistical calculator or software, you can enter the values of n (15), p (0.12), and the range of x (from 3 to 15) to get the desired probability.

(c) The mean (μ) and standard deviation (σ) of the number of individuals with conditions caused by outside factors can be calculated using the formulas for the binomial distribution:

Mean (μ) = n * p

Standard deviation (σ) = √(n * p * q)

Plugging in the values, we have:

Mean (μ) = 15 * 0.12 = 1.8

Standard deviation (σ) = √(15 * 0.12 * 0.88) ≈ 1.124

Therefore, the mean number of individuals with conditions caused by outside factors is 1.8, and the standard deviation is approximately 1.124.

The conclusions that can be made is because of ringing the area of phloem is cut and the food is not translocated further hence the food gets collected on that area thus it gets swollen.

Girdling, also known as ring-barking, is the full removal of the bark from all around the perimeter of a branch or trunk of a woody plant. This bark is made up of cork cambium, sometimes known as "phellogen," phloem, cambium, and occasionally even xylem. In the ringing experiment, a complete ring of tissue is excised from a dicot plant at a specific height above the ground outside the vascular cylinder. Water can flow freely from roots to the aerial regions because the xylem is intact.

Phloem, or food-carrying tubes, transport food made from leaves to other sections of the plant. Food produced by the leaves will not be able to get to other sections of the plant if the food-carrying tubes are removed. Because of this, the food builds up near the cut, causing the stem to bulge.

Thus we can conclude that the outer bark of the woody plants consist of the phloem tissues which is responsible for the movement of food inside the plant.

If you are focusing on the biology aspect of a slurry tank, your presentation could cover the following topics:

Microorganisms: The slurry tank is home to a diverse range of microorganisms, including bacteria, fungi, and protozoa. These microorganisms play a crucial role in the biological breakdown of the waste material in the tank.

Anaerobic digestion: Anaerobic digestion is the process by which organic material is broken down by microorganisms in the absence of oxygen. This process is central to the functioning of a slurry tank, as it is the primary means by which bio-waste is converted into energy.

Methane production: As part of the anaerobic digestion process, microorganisms in the slurry tank produce methane gas. This gas can be harnessed as a source of renewable energy, either by being burned to generate electricity or by being used as a fuel for vehicles.

pH levels: The pH level of the slurry tank is a critical factor in maintaining the optimal conditions for the microorganisms to thrive. The pH level can be affected by various factors, including the type of waste material being added to the tank and the rate of digestion.

Nutrient cycling: The slurry tank is an excellent example of nutrient cycling in action. As the microorganisms break down the waste material in the tank, they release nutrients such as nitrogen and phosphorus, which can be used to fertilize crops or other plants.

Challenges: Despite the many benefits of using slurry tanks to convert bio-waste into energy, there are also several challenges associated with their use. These challenges include managing the odors associated with the process, ensuring the proper mixing of the waste material in the tank, and preventing the buildup of toxic substances.

By covering these topics, you can provide a comprehensive overview of the biology aspect of a slurry tank and highlight the many ways in which this technology is helping to reduce waste and promote sustainable energy production.

The correct answers are: small ribosomal subunit, initiator tRNA, and messenger RNA.4. Translation initiation is now complete, and the ribosome is ready to proceed with the elongation phase of protein synthesis.
The terms directly involved in this process are:

1. Small ribosomal subunit
2. Initiator tRNA
3. Messenger RNA (mRNA)
4. Large ribosomal subunit

Here's a step-by-step explanation of translation initiation:

1. The small ribosomal subunit binds to the mRNA molecule, searching for the start codon (AUG).
2. The initiator tRNA, carrying the amino acid methionine, recognizes and binds to the start codon on the mRNA through complementary base pairing.
3. Once the initiator tRNA is in place, the large ribosomal subunit associates with the small subunit, forming a complete ribosome.
4. Translation initiation is now complete, and the ribosome is ready to proceed with the elongation phase of protein synthesis.

The amino acid residue that is closest in position to the initial alanine residue on the same face of the helix will be located three residues away from the alanine residue in the direction of the helix.

When a peptide sequence forms an α-helix, there is a repeating pattern of amino acid residues along the helical backbone. In the case of the peptide sequence aefflamep, if it forms an α-helix, the initial alanine residue would be located at the beginning of the helix, with the subsequent amino acids following in order.

The fourth residue in the sequence is a leucine (L), and this residue would be located three residues away from the initial alanine residue on the same face of the helix.

Therefore, in the α-helical conformation of the peptide sequence aefflamep, the leucine residue would be closest to being in the same position on the same face of the helix as the initial alanine residue.
