Answer:
From the given Options, Option C is correct.
the inheritance of the alleles from each parent is completely random but in a population, there may be natural selective pressure from the environment to favor different levels of expression
Explanation:
The evolutionary basis of human skin color stems far back to the genetic mutations involved in skin pigmentation. Although the diversity of skin color is a characteristic trait of humans, These variants and their evolution reveal that the history of skin color is much older than previously thought.
The evolution of various variations in the human skin color is a result of selective forces which is an environmental factor that favors various levels of expression. Thus, the best option that explains the basis of human skin color in terms of evolutionary trend is Option C.
The train speeding down the track. The faster the train moves diesel fuel the train uses. That means the faster the train goes, the more what it needs?
Answer:
I really think that this is engineering or maths but this not for biology
FOR SURE
The train speeding down the track. The faster the train moves diesel fuel the train uses. The faster the train goes the more it need energy.
What is energy?Energy is defined as a quantitative quality that is conveyed to a person or a physical system and is discernible in the way work is done as well as in the way heat and light are produced. It is important because it is a fundamental human requirement, energy plays a significant role in our daily lives. The primary energy source is the sun.
Railroads used to run their locomotives on petroleum-based diesel fuel, but they are now powered by renewable diesel and biodiesel blends. Biodiesel and renewable diesel are both produced using renewable energy sources rather than fossil fuels.
Thus, the train speeding down the track. The faster the train moves diesel fuel the train uses. The faster the train goes the more it need energy.

The disorder known as cystic fibrosis (CF) is inherited in a recessive autosomal manner. In populations of Northern European descent, the frequency of people with CF is about 1 in 2,500. Assuming Hardy-Weinberg equilibrium for this disorder, answer the following: A. Assuming Hardy-Weinberg equilibrium, what percentage of people in the population would be expected to be heterozygous carriers
Answer:
The correct answer is -
A. 3.9% people in the population would be expected to be heterozygous carriers
Explanation:
The genotype frequency for the CF affected is 1/2,500,
= 1/2500
= 0.004. This is equal to q^2
here q = frequency of recessive alleles combination or CF people. (H-W equation => p^2+q^2+2pq=1)
The allele frequency is the square root of q^2 value, which equals 0.02. The frequency of the dominant allele or p would be
1 - 0.02 = 0.98 (p+q = 1)
The frequency for the CF combinantion =0.004
the dominant or unaffected people genotype
= (098)^2
= 0.96;
and for the heterozygote, it is
= 2pq
=2(0.98)(0.02)
= 0.039 or 3.9%

Lake trout are found in the Great Lakes because they can only live in cold environments. This example shows how the number of populations an ecosystem can support is limited by _______. A. water B. air C. food D. temperature
Answer:
D. Temperature
Explanation:
Several environmental factors affect how dense or sparsely populated an ecosystem is. These factors include; temperature, pH, predation, food, etc. The presence or absence of this factors can either limit or enhance the number of populations that exists in an ecosystem.
According to this question, Lake trout are reported to be found in the Great Lakes because they can only live in cold environments. Since temperature is a measure of how hot or cold a substance/place is, this means that this exemplifies how a number of populations an ecosystem can support is limited by TEMPERATURE.

would it be better to mine in a wilderness area than a developed area?
Answer:
Yes.
Explanation:
Mining in a area of wilderness can provide great succes as long as you know the area well and know some things about where to mine and not.
Answer: Yes, it is better to mine in a wilderness area than a developed area.
Explanation: Mining is carried out to gather raw materials that serve as the foundation for any country's or region's growth. It is more likely to occur in a wilderness area than in a developed area because mining usually has a negative impact on the environment.
The ores recovered by mining, such as oil, coal, metals, and others, cannot be obtained from any developed location, and the mining process destroys settlements in developed areas.

A possible consequence of staphylococcal infections is glomerulonephritis. Glomerulonephritis affects the filtration membrane by causing the basement membrane underlying the glomerular endothelium to lose its negative charge. The negative charge on the basement membrane is what prevents plasma proteins from entering the filtrate. Thus, with this condition, proteins can enter the urine (proteinuria). What effect will this have on the glomerular filtration rate
Answer:
Proteinuria is a general characteristic in different types of kidney and renal diseases where different types of proteins come in the filtrate. This causes a diminishing in the glomerular filtration rate due to the reason that proteins in the filtrate cause aggravation and scarring.
Explanation:
The value of Glomerular Filtration Rate or GFR is given as
[tex]GFR=K_f(P_c-P_b)-\pi_c[/tex]
Here
K_f is the Permeability constant of glomerular capillariesP_c is the hydrostatic pressure of the glomerular capillaryP_b is the hydrostatic pressure of the Bowman's spaceπ_c is the oncotic pressure of the glomerular capillaryAs the proteins start to occur in the filtrate, they reduce the [tex]P_c[/tex] and increase the value of [tex]P_b[/tex]. This leads to a reduced difference [tex]P_c-P_b[/tex], which leads to reduced GFR as they are directly proportional.
Carbon dioxide is a naturally occurring gas that is vital to plant and animal life, yet carbon dioxide emissions from burning of fossil fuels are expected to result in significant climate change within 100 years. Should carbon dioxide be considered to be a pollutant? Support your position by providing reasons why or why not.
Answer:
Yes, it should be considered a pollutant
Find the reason below
Explanation:
A pollutant is any substance that poses threat or causes harm to the sustainability of the environment. As rightly stated in this question, carbon dioxide (CO2) is a naturally occuring gaseous constituent of our atmosphere. It is vital to both animal and plant life as it is utilized by plants to synthesize their food (glucose), which is the starting point for the flow of energy.
Although CO2 plays a major role in sustaining life, it is also a major cause of GLOBAL WARMING. Carbon dioxide is considered the most important greenhouse gas as it has the ability to trap and emit heat, contributing to the global rise in atmospheric temperature. This causes a lot of harm and environmental disturbance, hence, CO2 despite its beneficial purpose, should be considered a POLLUTANT.
Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the male minnows all had a moderate number of spots. Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots. After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Answer:
Geographic isolation
Explanation:
Geographic isolation occurs when a population is split by geographic factors, such as the flood mentioned. They can become separate species over time and will no longer be able to produce viable offspring. Hope it helps :)
Consider the principles and applications of classification systems (e.g., ICD-10, HCPCS) and medical record auditing used within a clinical documentation improvement (CDI) program. Appraise the value and challenges of a quality CDI program by defending the need for ongoing CDI program support and critique at least two (2) challenges in the CDI process. Make connections between auditing, accurate diagnostic and procedural coding with classification systems, and CDI programs. Your executive summary should reflect upon the need for CDI and best practices for ensuring compliance
Answer:
Explanation:
In a clinical documentation improvement (CDI) scheme, the following are the principles and implementations of classification schemes (e.g., ICD-10, HCPCS) as well as medical record auditing:
ICD-10 (International classification of diseases, 10th edition) codes offer additional comprehensive information for assessing healthcare quality, safety, and its' effectiveness. These codes aid in the recording of diseases in medical history and the tracking of epidemiological patterns. They also aid in the decision-making process for medical reimbursement. HCPCS (Healthcare Common Procedure Coding System) exists as a coding system for identifying product devices, equipment, and facilities not covered by CPT codes. When encoding bills, these codes reflect medical procedures through Medicare, Medicaid, as well as other third-party payers.
CDI provides a shared interface for data sharing and real-time monitoring, allowing clinical teams to communicate more effectively.
The following are the three obstacles and challenges in the CDI process:
Eliminating the discrepancy between clinical terms used among healthcare providers and medical coding terminology applied for reimbursement. Hiring the right CDI for the job, i.e. someone who knows the ethical and legal concerns affecting the healthcare provider request and inquiry process and has a basic understanding of coding guidelines. Maintaining correct and precise paperwork documentation across treatment transitions and in other healthcare environments is a top priority.
Timely auditing, correct diagnostic and procedural code labeling, and grading processes help CDI practitioners track their practice and maintain the highest degree of program integrity.
Clinical reporting is required in order to meet quality standards. There is a need for CDI because it encourages coding, which is the foundation to accurate sales and compensation because it offers quality records, which in turn supports patient coordination in hospitals.
Examining records thoroughly for missing, unclear, or contradictory details, physicians responding promptly and fully to CDI professionals' questions, inquires, and active cooperation from prescribing physicians are some of the best practices to undertake to ensure compliance. These procedures assist hospitals with capturing the correct codes in order to receive fair reimbursement for the care they offer.
Dinosaurs evolved over millions of years and became well-suited to their
environment. Unfortunately, dinosaurs did not have the ability to adapt to the
climatic change that occurred sixty-five million years ago due to the asteroid
collision. Which statement best describes why the dinosaurs were unable to survive
this event?
Answer:
Dinosaurs did not have the ability to adapt to the climatic change that occurred sixty-five million years ago due to the asteroid collision.
Explanation:
The rapid extinction of dinosaurs is believed by many scientists to have been caused by the very powerful meteorite impact on the northern Yucatan Peninsula about 65.5 million years ago, which created the Chicxulub crater. After that event, no dinosaurs have been found other than early birds, suggesting that all died out during or just after this short period.
The event enabled mammals to evolve and fill many of the ecological niches that were liberated since the disappearance of the dinosaurs. Even about a third of all known mammals disappeared in this mass extinction.
