6.25% is the probability .

What does a probability simple definition entail?

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Both proportions between 0 and 1 and percentages between 0% and 100% can be used to describe probabilities.

                          Probability is a measure of the likelihood that an event will occur or the likelihood that something will happen. Probability is the measure of how likely it is that a coin will land heads up after being tossed into the air.

0.5 • 0.5 • 0.5 • 0.5 = 0.0625 or 6.25%

There’s a 0.5 chance of getting a y allele from parent 1, 0.5 chance of getting an r allele from parent 1, 0.5 chance of getting a y allele from parent 2, and 0.5 chance of getting an r allele from parent 2.

Answer:

The correct answer is - 3 × 10⁻²

Explanation:

first find LKo = length of BDNA/ 10.5 bp/turn

= 4200/10.5

= 400

now calculate Δ LK= LK - LKo

ΔLK = 412-400

ΔLK = 12

now, superhelix density  = ΔLK/LKo

⇒ 12/400 = 0.03

= 3×10⁻²

Thus, the correct answer is - 3 × 10⁻²

Internal waves:

-P-waves: primary waves because they are the first to arrive at a seismograph. They are compressive-type waves and cross the planet via solid, gas, or liquid.

-S-waves: secondary waves. They are transversal-type and their vibration is perpendicular to their movement and propagation. They can't cross through the Earth's nucleus.

Superficial waves:

-L-waves: love waves. They travel above the Earth from side to side, as a result of the interference of multiple S-waves propagated on a superficial elastic layer.

-R-waves: Rayleigh waves, they're a superficial acoustic type of wave that travels along the surface of solids.

I think that the most dangerous time period for a patient with cystic fibrosis is;

Cystic fibrosis is a disease that results when there is a malfunctioning of the epithelial cells that line the walls of the sweat glands, lungs, digestive, and reproductive systems.

It causes the skin to taste salty. The patient suffers from shortness of breath and recurrent pneumonia.

In the graph shown, ages 35-44 seem most dangerous for patients with cystic fibrosis because that is the time when the various bacteria that affect the lungs of patients reach their peak and maintain a constant rate.

Therefore, the patients have a high rate of succumbing to the disease during this period.

Explanation:

Endurance deals with how long you can do something that puts a physical strain on your body and not necessarily how much strain at once. That being said both physical strength and emotional strength play a big role in this. Physical strength is needed to be able to exert yourself and accomplish the initial task in the first place. While emotional strength is also needed in order to not give up and persevere as long as possible. Without will power (emotional strength) you will give up as soon as you are given the opportunity.

Dependent variable for the study will be Frog population .

A dependent variable is the variable that changes as a result of the independent variable manipulation. Dependent variables are also called as response variables.

A dependent variable is what you measure in the experiment and what is affected during the experiment. The dependent variable responds to the independent variable. It is called dependent because it "depends" on the independent variable. The independent variable in a research study or experiment is what the researcher is changing in the study or experiment. It is the variable that is being manipulated.

Explanation:

They structure muscles, accelerate compound responses, and carry out numerous other cell roles. Nucleic acids are natural mixtures that incorporate DNA and RNA.

Nucleic acids are huge biomolecules that assume fundamental parts in all cells and infections. A significant capability of nucleic acids includes the capacity and articulation of genomic data. Deoxyribonucleic corrosive, or DNA, encodes the data cells need to make proteins. A connected sort of nucleic corrosive, called ribonucleic corrosive (RNA), comes in various sub-atomic structures that assume different cell parts, including protein blend.

Nucleic acids are made of nitrogen-containing bases, phosphate gatherings, and sugar atoms. Each kind of nucleic corrosive has a particular design and assumes an alternate part in our cells.

Because of the universality of the genetic code, the polymerases of one organism can accurately transcribe a gene from another organism.

Answer:

Carbohydrates, Proteins, and Lipids

Explanation:

Answer:

If the molecule of an element contains 1 atom it's called a monoatomic molecule. E.g. Na, He, etc. If the molecule of an element contains 2 atoms it's called a diatomic molecule.

the evidence that all life on Earth shares common features is that All life on Earth performs transcription and translation in a similar fashion. and All life on Earth has cells surrounded by membranes.

What is transcription and translation?

The process of transcribing a piece of DNA into RNA is known as transcription. Messenger RNA is created when segments of DNA are translated into RNA molecules that can encode proteins. Translation is the process by which ribosomes in the cytoplasm or endoplasmic reticulum create proteins following the transcription of DNA to RNA in the cell's nucleus. The entire process is known as gene expression.

What is cell membrane?

The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment. The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
