Sickle cell anemia is an inherited autosomal recessive disease, which means that only the homozygous recessive individuals have the disease, heterozygous individuals are carriers, and homozygous dominant individuals are normal.

Let "N" represent the normal gene, i.e. without the mutation, and "S" represent the gene with the sickle cell mutation.

The genes of the parent without the disease will be NN, and it will produce gametes with the normal allele "N"

The genes of the parent that carries the disease will be NS and will produce gametes with the normal allele "N" and the recessive allele "S"

For both parents, each allele will have a 0.50 probability, this is granted by the random segregation of genes during meiosis.

To construct the Punnet square, you have to write the gametes of one of the parents in the first row and the gametes of the second parent in the first column. Write the corresponding probabilities for each gamete in each cell:

Cross each column with each row to determine the gene combination of the offspring:

When you cross the first column with the first row, the resulting genotypes will be NN, to determine its probability you have to multiply the probability of the individual inheriting each allele:

Write the result in the Punnet square:

Repeat for all combinations:

-First-row + second-column, the genotypes for the offspring will be NN, and its associated probability is equal to the product of the probabilities of each allele:

-Second-row + first-column, the genotypes of the offspring will be NS, and the associated probability is equal to the product of the probabilities of inheriting each allele:

-Second-row + second-column, the genotypes of the offspring will be NS, and, as before, the probability associated will be:

Write the results in the Punnet square:

As you can see, the offspring will have two possible genotypes NN and NS, to determine the percentage for each you have to add the probabilities of the cells that show the same genotype:

So, 50% of the children will be homozygous dominant (NN) and 50% of the children will be heterozygous (carriers).

As you can see, since there was only one parent that carried the allele S, there is no possibility that their children will carry the homozygous recessive genotype SS. The probability of their children having sickle cell anemia is 0%

These factors are the same climatic factors that can either promote or inhibit plant growth and development and, eventually, crop productivity.

Vertical agriculture is not a reliable urban substitute, as it lacks many resources to implement, which makes implementation difficult in poorer countries.

The vertical garden is an agriculture concept for growing plants inside buildings or multi-story skyscrapers, often called farmscrapers, a term derived from the English skyscraper. In these buildings, which would function as large greenhouses, agriculture involves the use of technologies such as hydroponics to aid in plant growth. Some projects include the practice of livestock (especially poultry) on the lower floors.

While vertical farming may be an urban substitute for expansive farmlands, there is no guarantee that it will be a dependable substitute for traditional farms. This is true.

Vertical farming is the method of growing crops in vertically stacked layers in a controlled environment. Vertical farming is utilized in urban places where there is limited space for crops to grow.

However, we cannot consider vertical farming to be a reliable substitute for traditional farms due to the high maintenance level and cost of vertical farming. It will be challenging to implement hydroponics and other plant-growth techniques on conventional farms.

As a result, vertical farming cannot be used in place of traditional farming.

The TCA cycle's starting and stopping requirements include the acetyl group, oxaloacetic acid, coA, citric acid, and others.

What is the TCA cycle, and what makes up the TCA cycle?

Tricaboxylic acid (TCA), commonly known as Krebs cycle, requires acetyl coenzyme A and a particular quantity of water to begin.

An substantial amount of citric acid is produced during the initial reaction between water and acetyle coA.

A molecule of coA is released as a result of this process, which is catalysed by the enzyme citrate synthase.

The following stage is isomerization, in which a substrate is converted from citrate to isocitrate.

Following decarbocylation, alfa ketoglutaric acid is produced, and succinyl coA is then oxidised to OAA in TCA cycle.

According to the given data It most likely rain on Day 4 98%.

The correct option is D.

The relative humidity is typically between 90 and 99 percent when it is raining, but it is rarely greater than 100 percent. Rain happens when water droplets get too large to be maintained in the atmosphere and fall to the ground. Clouds are created when invisible water vapor gas condenses to visible water droplets.

The water vapour content controls the amount of rainfall during extremely strong downpours, in which all of the water in the atmosphere is frequently soaked out. We are more likely to experience rain when the humidity is higher because water vapor expands at a faster rate.

The dilution of 1 mL stock in 99 mL of water is a 100-fold dilution. Option C.

A 100-fold dilution is a dilution involving 1 part of the stock solution and 99 parts of diluting solvent.

A stock solution is a standard solution from which solutions of lower concentrations can be prepared by dilution.

Thus, when you take 1 mL of a stock solution and dilute it with 99 mL of water, you are carrying out a 100-fold dilution with water being the solvent used in dilution.

A 100-fold dilution is different from a 1000-fold. The latter requires 1 part of the stock solution in 999 parts of diluting solvent.

For 10-fold dilution, 1 part of the stock is taken and diluted with 99 parts of the diluting solvent.

Those messages are sent to the hand using sensory neurons.

Axons are long single fibers that carry messages from the cell body to the dendrites of other neurons or other body tissues such as muscle. In muscles, this electrical message causes them to contract or shorten. Think of catching a ball. The brain tells neurons to send electrical signals to the neuromuscular junction. This releases neurotransmitters into your finger muscles, which contract to catch the ball.

Motor neurons release chemicals that are taken up by muscle fibers. This causes the muscle fibers to contract and the muscle to move. Neurons carry messages from the brain through the spinal cord. These messages are sent to the muscles, directing muscle fibers to contract and causing the muscles to move. Neurons that are sending signals release chemicals called neurotransmitters. This chemical binds to receptors on the surface of receiving neurons.

Plasmolysis is the loss of water by plant cells after being placed in a solution with a higher concentration of solute than the cells. This is called a hypertonic solution. Osmosis causes water to flow from the cell into the surrounding liquid.

Plasmolysis is the process by which cells lose water in hypertonic solutions. When cells are in a hypotonic solution the reverse process cytolysis or cell lysis occurs resulting in a decrease in external osmotic pressure and a net flow of water into the cell. When plants are not watered the extracellular fluid becomes isotonic or hypertonic causing water to leave the plant cells.

This causes a loss of turgor pressure. You will probably notice it as a wilt. In more concentrated solutions cell contents lose water by osmosis. They contract and move away from the cell wall. Cells are limp It is cytolyzed. When a high concentration of salt is placed on the outside of the cell membrane water leaves and binds with the cell. As water is lost by this movement, the plant cells shrink and die. Because of this, salt can kill plants. It leaches water out of the cells.

Solar energy is an apparent infinite source of energy, which alleviates the pressures associated with raw materials searching. Given said that, solar energy could be conceived as the more parsimonious source of energy, as it is the motor of biological systems that gave rise to life as we know (that is, photosynthetic organisms). So, to sum up, it is "infinite", cheap, and easy to exploit (at least in tropical latitudes).

Given the information about PKU and the PAH, we can evaluate the options:

A is false because it says the protein is functional in individuals with the disease.

B is more likely to be true because when the protein produced by PAH isn't functional, the phenylalanine builds up.

C is false because it says the protein isn't functional in healthy individuals.

D is false because phenylalanine is an essential amino acid, which means the body can't produce it.
