One example of a contagious disease is the flu, also known as influenza.
The flu is caused by a virus known as the influenza virus, which belongs to the Orthomyxoviridae family.
Symptoms of the flu include fever, chills, cough, sore throat, runny or stuffy nose, muscle or body aches, fatigue, and sometimes vomiting or diarrhea. Symptoms typically appear within 1-4 days after infection and can last up to a week.
The flu is primarily spread through respiratory droplets when an infected person talks, coughs, or sneezes. The virus can also be spread by touching a surface or object that has the virus on it and then touching your mouth, nose, or eyes.
There is a cure for the flu. The primary treatment for the flu is antiviral medication, which can shorten the duration of the illness and prevent severe complications. Antiviral drugs can be taken within the first 48 hours of symptoms appearing to be most effective. Vaccination is the best way to prevent the flu. Your doctor can recommend the best treatment course based on your situation.

In animal cells, a pair of small cylindrical structures composed of microtubules that duplicate during interphase and move to opposite ends of the cell during prophase called centrioles.
Describe centrioles.
The majority of eukaryotic cells contain centrioles, which are cylindrical organelles. At the center of the cell, they are found in pairs and are made of microtubules. Numerous cellular processes, such as the development of cilia and flagella as well as the structuring of the cytoskeleton, are carried out by centrioles. Centrioles also play a role in the development of the mitotic spindle, which divides chromosomes during animal cells.

Although they are ecological connections, competition and predation are not mutualistic. Competition is an indirect interaction over resources, whereas predation does not happen over an extended period of time.
Competition is an interaction between two populations of closely related species that are vying for the same resources.

What process happens during prophase I of meiosis and creates genetically unique daughter cells?.
There is a breakdown of nuclear structure in prophase 1. It is also possible to see how chromatin condenses into chromosomes. The two chromatid-containing homologous chromosomes unite to generate tetrads by connecting at their centromeres. At this point, "crossing over" takes place, resulting in genetic variety.
Homologous chromosomes (one from each parent) pair along their lengths during meiosis. Chiasma points are where the chromosomes cross. The chromosomes split and reassemble at each chiasma, swapping some of their genes. Genetic variety is produced by this recombination. Homologous chromosomes link up and create synapses during prophase I, a process that only occurs during meiosis. The paired chromosomes are known as bivalents, and it is now clear that genetic recombination is what causes chiasmata to occur. These can be seen under a microscope thanks to chromosomal condensation.

What are the colours observed by plants the green light of the sunlight is blocked How will the photosynthesis be affected?.
The colors absorbed by the plants are blue and red and they reflect green light back, hence appear so. Hence, there will be no effect if green light of the sunlight is blocked.
The plants appear green because they reflect the green light back into the environment. Therefore, blocking green light won't have an impact on photosynthesis. Plants reflect back the green light because they absorb red and blue light, which is when photosynthesis is at its peak.
Light is absorbed during photosynthesis, and the energy from that light is used to create sugars that the plant can utilise. Photosynthetically active radiation is the term for the spectrum of light that plants can use for photosynthesis, which also happens to be the same spectrum that we can see.

There are five main points to be considered during natural selection. They are variation, adaptation, selection, inheritance, and time.
Populations of living creatures fluctuate over time due to a fundamental mechanism called natural selection. It is so straightforward that it can be divided into five simple processes, referred to here as VISTA (variation, inheritance, selection, time, and adaptation).
Variation: Individuals in a population are different from one another because they have different genetic makes up than other individuals. This is true for all species.Inheritance: Some of a parent's genetic makeup is transferred to their children.Selection: Some people have inherited traits (genes) that help them live longer or have more children. These offspring have a higher likelihood of surviving and having children of their own. Their genes spread throughout the entire population as a result.Time: Selection leads to changes in species throughout time. Successful variants build up throughout time as these changes happen over days, decades, or even millions of years.Adaptation: The change of an organism to its environment to increase its chances of survival is known as an evolutionary adaptation or adaptation.To know more about natural selection:

C. Yes; the product of any two monomials is a monomial..
D. No; the product of two monomials could be a rational number.
The correct explanation of the set of monomials closed under multiplication is Yes, the product of any two monomials is a monomial.
What is monomial and how to multiply monomial by monomial?
An algebraic expression with only one term is called a monomial. It contains only constants, variables, and exponents. Monomials can be manipulated using the basic operations of addition, subtraction, multiplication, and division. Examples of monomials include 3x2, 4, and 7xy. To multiply monomials, you multiply the coefficients, then multiply the variables. For example, to multiply (3x) and (5y), you would multiply 3 and 5 to get 15, then multiply x and y to get xy. So, the answer would be 15xy.
When two monomials are multiplied together, the result will always be another monomial, which is composed of the products of the coefficients and variables of the two monomials. For example, if we multiply 2x2 and 3x4, the result will be 6x6, which is a monomial.

It is used by data scientists, analysts, and developers to build and deploy machine learning models. It offers a variety of powerful tools for data preparation, modeling, and deployment, as well as a range of algorithms for supervised and unsupervised learning.
In the given question, the percent yield can be calculated by dividing the amount of water produced (18 g) by the amount of reactant that was used (4 g). This gives us an answer of 4.5, which can be expressed as a percent yield of 450%.
The percent yield is an expression of the efficiency of a reaction. It is calculated by dividing the amount of product actually produced by the amount of product that should have been produced (based on the stoichiometric ratio). In this case, the reaction of 4 g of hydrogen with excess oxygen should have produced 18 g of water. Since 18 g of water were actually produced, the percent yield is 100%. This means that the reaction was 100% efficient and all of the reactants were used up in the reaction.

What do you mean by Bipedalism?
Bipedalism is the ability of an organism to move using only two limbs, usually the legs. It is a form of locomotion used by most humans and some other animals, such as apes and birds. Bipedalism increases the range and speed of movement, as well as providing better balance and stability.
Darwin’s theory of the origin of bipedalism explains that the upright posture of humans evolved as an adaptation to the changing environment of the African savanna. According to Darwin, a bipedal posture allowed for the freeing of the hands, increasing the efficiency of foraging and tool-making. This theory has been widely accepted as the most plausible explanation for the emergence of bipedalism, as it is supported by the fossil record and other evidence. The theory has become central to our understanding of human evolution, as it has been confirmed by numerous archaeological discoveries and is supported by the current scientific consensus.
