What are the values of a, b, and c in the quadratic equation 0 = 5x – 4x2 – 2? a = 5, b = 4, c = 2 a = 5, b = –4, c = –2 a = –4, b = 5, c = –2 a = 4, b = –5, c = –2
Hey there! :)
Answer:
The 3rd choice. a = -4, b = 5, c = -2.
Explanation:
Rearrange the quadratic equation given into the form 0 = ax² + bx + c:
0 = 5x - 4x² - 2 --> 0 = -4x² + 5x - 2
The corresponding coefficients for the a, b and c values are:
a = -4
b = 5
c = -2.
The given quadratic equation must be first rearranged in the form ax2- bx-c. From this, we can find the values of a= -4, b= 5, and c= -2
How can a quadratic equation be defined?Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is ax² + bx + c = 0.
Quadratic equations are commonly used in situations where two things are multiplied together and they both depend on the same variable. For example, while working with the area, if both dimensions are represented in terms of the same variable, you use a quadratic equation.
Throwing a ball, shooting a cannon, diving from a platform, and hitting a golf ball are all examples of situations that can be modeled by quadratic functions.

A student recorded the height of each student in the school. She then made a bar graph of her results. She observed that
the results form a bell-shaped curve. The student could use her graph as evidence to support which argument?
Height is affected by multiple pairs of genes on different chromosomes.
The alleles for tall height and short height are codominant.
The allele for being tall is dominant to the allele for shorter heights.
There are three alleles for height that demonstrate incomplete dominance.
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The height is a quantitative trait, it is a phenotypic feature that presents a continuous range of variation in the population. The cumulative effects of many genes and the environment produce a normal distribution bell-shaped curve when they are drawn, this being a characteristic of quantitative genetic traits. Examples of quantitative traits include, among others, height, metabolic rate and weight.
The student could use their graph as evidence to support the argument that "The alleles for tall stature and short stature are codominant."
What is a Codominant gene?Codominant: Autosomal codominant inheritance is the condition in which the heterozygote has the characteristics determined by both alleles (dominant and recessive).
What is allele?Allele genes are those that occupy the same locus on homlogous chromosomes and are involved in determining the same character.
With this information, we can conclude that the genes alleles of the students in this class are codominant.

Based on what you know of bone features, what do you think this canal is for? Why would we need a hollow space in this area of this bone?
Answer:
The mandibular canal, also referred to as the Inferior Alveolar Canal (IAC), sits within the mandible. It serves the purpose of housing the inferior alveolar nerve which is responsible for supplying sensation to the lower teeth.
This canal also houses the inferior alveolar vein - a dental vein whose function is to (with the assistance of the posterior alveolar artery) drain blood from the lower teeth and jaw.

Explanation:
Which capillary would be least likely to allow substances to enter or exit the blood due to tight junctions that join the endothelial cells
Answer:
Those capillaries that have endothelial cells tightly attached have an increase in cell-to-cell junctions, such as desmosomal junctions that are poorly permeable to substances.
These capillaries generally function as conductors or collectors and not as permeabilizers like the pulmonary capillaries that are fenestrated and allow a high passage of substances and gases.
The capillaries are waterproof and prevent the passage of substances or fluids such as in the blood-brain barrier that is very selective
Explanation:
The blood-brain barrier is too selective since it is not favorable for the organism that many fluids, drugs, substances or chemical compounds enter the brain space.
This is the reason why the vessels are waterproof and why pharmacology was challenged to invent drugs that could cross this barrier since it was considered impossible.
An example is dopamine, which in parkynson's disease the levo group is added to dopamine, thus forming levodopamine as a product, this is the only way that the drug crosses the blood-brain barrier and can pass the impermeable barrier generated by capillaries with endothelial cells that are close to each other or closely linked
A microbiologist would like to use a noncompetent genus of streptococcal bacteria, Enterococcus faecalis, as a cloning host to express genes from Streptococcus pneumoniae, which is naturally competent. Is this possible? Group of answer choices
Answer:
Yes, with the assistance of electroporation the bacteria Enterococcus can be made competent, and afterward, the Streptococcus bacterial genes can be presented within the Enterococcus with the help of a cloning vector.

A population of birds lives on a small island. Another population of the same species lives on the mainland. The distance between the island and the mainland is too great for birds to fly back and forth. Recently, a series of sandbars and tiny islands have formed between the island and the mainland?
Answer:
Explanation:
Based on this information it can be said that this formation between the islands and the mainlands will most likely cause an increase in gene flow between the bird populations. Since the islands and the mainland are now connected birds from both these two different habitats will begin mating and producing progeny, thus causing gene flow to increase between these species.
Answer:

PLEASE HELP. DONT ANSWER IF YOU DONT KNOW. Name any three specifications that reduce carbon dioxide expenditure and promote biodiversity.
Answer:
A carbon footprint is the total greenhouse gas (GHG) emissions caused by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent.[1] Greenhouse gases, including the carbon-containing gases carbon dioxide and methane, can be emitted through the burning of fossil fuels, land clearance and the production and consumption of food, manufactured goods, materials, wood, roads, buildings, transportation and other services.[2]
In most cases, the total carbon footprint cannot be calculated exactly because of inadequate knowledge of and data about the complex interactions between contributing processes, including the influence of natural processes that store or release carbon dioxide. For this reason, Wright, Kemp, and Williams proposed the following definition of a carbon footprint:
Specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:
1. Provide tree plantation through urban afforestation.
2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen
3. By promoting fruits and shade for the neighborhood.
What is Carbon Dioxide?Carbon dioxide is defined as the chemical compound which is made up of molecules each containing a carbon atom bonded twice to two oxygen atoms and is found in the gaseous state at room temperature. In air, carbon dioxide is transparent to visible light but absorbs infrared radiation which acts as a greenhouse gas.
This is a minor component of the Earth's atmosphere at about 3 volumes in 10,000 employed by plants in the combustion of carbon-containing material, in fermentation, and in the respiration of animals and in the photosynthesis of carbohydrates.
Thus, specifications that reduce carbon dioxide expenditure and promote biodiversity are as follows:
1. Provide tree plantation through urban afforestation.
2. It has low concentration of carbon dioxide as plants absorb this gas and release oxygen
3. By promoting fruits and shade for the neighborhood.
