1) Use the following situation and tables to choose the correct answer.
Randomly sampled students from two high schools were asked what color the district should paint the new stadium. The results are presented in the following tables:
Stadium Color - North Valley High
Color: Survey Results:
silver 30
blue 54
teal 36
Stadium Color - South Hills High
Color: Survey Results:
silver 78
blue 24
teal 18
Make an inference comparing which color each of the two high school populations should choose for the stadium, based upon a qualitative comparison of the sampled data.
A.) North Valley High should choose silver to give the minority of the students who selected silver a win in the selection process. South Hills High should choose teal because a minority of their sampled students selected the color teal than other colors.
B.) North Valley High should choose blue because more of the sampled students selected the color blue compared to the other colors in the survey. South Hills High should choose silver because more of the sampled students selected the color silver than other colors.
C.) North Valley High should choose teal because that color was selected between the other two colors and would appeal to a broader base of students. South Hills High should choose blue in order to appeal to a broader base if its students.
North Valley High should select blue because more of the sampled students picked the color blue compared to the other colors in the survey. South Hills High should select silver because more of the sampled students picked the color silver than other colors.
This is the correct inference based on the given data. The survey results show that blue was the most popular color among the North Valley High students, and silver was the most popular color among the South Hills High students. Therefore, it would make sense for each high school to choose the color that was most popular among their respective student populations.

What is the blood group of a person who has neither antigen A nor B but is positive for antigen d
Answer:The blood group of a person who does not have antigen A or B but is positive for antigen D is classified as blood group O positive (O+).
Explanation: In the ABO blood typing system, there are four main blood types: A, B, AB, and O. These blood types are determined by the presence or absence of specific antigens on the surface of red blood cells. Antigens A and B are responsible for blood types A and B, respectively.
If a person lacks both antigen A and antigen B, they are considered to have blood type O. The positive (+) or negative (-) designation refers to the presence or absence of the Rh antigen, also known as the D antigen. A person who tests positive for the D antigen is Rh-positive.
Therefore, a person who does not have antigen A or B but is positive for the D antigen is classified as blood group O positive (O+).

Explain how energy flows in an ecosystem giving a specific food chain example. Be sure to use the following vocabulary (producer, primary, consumer, secondary consumer, tertiary (3rd) consumer, sunlight energy)
Answer:
Within the food chain energy can be passed and transferred from one organism to another. Whilst mammals get their energy sources from food – whether this be eating other animals or eating vegetation; plants get their energy from photosynthesis.
Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers.
They are then eaten by tertiary consumers and in a long food day these can be eaten by quaternary consumers. Each stage of a food chain is called a trophic level.
When food chains are linked together they form a food web.
So how does all this energy get into the food web, and how is it then distributed between organisms?
Plants harvest their energy from the sun during photosynthesis. This energy can then be passed from one organism to another in the food chain.
The organism that obtains energy from sunlight is called the producer. Often these are plants but in some circumstances it can be bacteria.
Even though it is producers that bring energy into the food chain from the sun it is consumers that make up the majority of the food chain. These can be predators, scavengers and parasites.
When a plant is eaten by a primary consumer, only 10% of the energy is passed on.
The low percentage of transferred energy can be attributed to different reasons like some of the organism not being eaten, incomplete digestion of the eaten organism, energy lost in excretory processes or energy lost as heat.
Consumers pass 20% of their energy onto other consumers. This is because they are more efficient than plants at passing on the energy. A lot of the energy is lost in excretion and some is lost in trying to maintain a constant body temperature.
When producers or consumers die they will be fed on by decomposers. Decomposers break complex materials into simple components after producers and consumers die, using up the energy they contain. In this way, minerals and elements needed by plants are released in a form that can be absorbed by them.
Sometimes there are plants that need to be killed. Herbicides will kill plants. However, they need to be used carefully as they could cause damage to plants you do not want to kill.
If you are wanting to get rid of pests (organisms that compete with humans for food and space) you would use pesticides or biological controls.
Pesticides are chemicals that are poisonous to pests. You can also use biological controls (other organisms) to get rid of pests. The organisms used as biological control are normally either predators or parasites of the pest organism. An example of this type of control is the ladybird, which feeds off aphids. Aphids can cause severe damage to crops.
However biological controls often act slower than pesticides. Also they can be bad as the organism itself may become the pest in time.
In the cause of transferring energy in animals, many farmers will restrict movement so that less energy is lost. In turn this energy can be transferred into body mass.
Also, the environment can be kept warm to reduce heat loss from the body.

Systolic blood pressure is dependent on the force and velocity of ventricular contraction (systole) and diastolic pressure dependent on the degree of vasodilation/constriction during ventricular relaxation (diastole). Explain this statement.
Answer:
Blood pressure is the force applied on the walls of the blood vessels by the blood. This force is perpendicular. There is to part of blood pressure systolic and diastolic, a single heartbeat consists of one systole, the contraction, and one diastole, the relaxation.
The pressure applied on the blood vessels due to the contraction of the heart is systolic and due to the relaxation of the heart is diastolic blood pressure.
Systolic blood pressure is directly proportional to the velocity and force of contraction whereas diastolic is due to relaxation of the heart.
The highest point of blood pressure is measured at the end of the contraction that is systolic blood pressure and the minimum blood pressure is at end of relaxation that is diastolic blood pressure.

A single gene with two alleles control variation in haemoglobin type in sheep. There are three different phenotypes corresponding to genotypes S^AS^A S^AS^B and S^BS^B respectively in a flock of 175 sheep the frequency of allele S^A was found to be 0.6 and frequency of allele S^B WAS found to be 0.4
Populations in Hardy-Weinberg equilibrium express the same allelic and genotypic frequencies through generations. Number of individuals expressing each phenotype: 63 sheep S^AS^A, 84 sheep S^AS^B, 28 sheep S^BS^B.
What is Hardy-Weinberg equilibrium?The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies in populations that is in equilibrium remain the same through generations. No evolutive forces are acting on these populations, so no evolution occurs.
Assuming a diallelic gene,
Allelic frequencies
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qGenotypic frequencies
p² (Homozygous dominant genotypic frequency), 2pq (Heterozygous genotypic frequency), q² (Homozygous recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Alleles Frequencies
S^A f(S^A) = p = 0.6S^B f(S^B) = p = 0.4Genotypes
S^AS^A ⇒ homozygousS^AS^B ⇒ heterozygousS^BS^B ⇒ homozygousWe need to get the number of animals expressing each genotype and phenotype. To do it, we just need to use allelic frequencies and calculate genotypic frequencies (p², 2pq, and q²), and then multiply these values by the total number of animals (N = 175).
Genotypic and Phenotypic frequencies
F(S^AS^A) = p² = 0.6² = 0.36
F(S^AS^B) = 2pq = 2 x 0.6 x 0.4 = 0.48
F(S^BS^B) = q² = 0.4² = 0.16
Number of individuals expressing each phenotype
S^AS^A ⇒ 0.36 x 175 = 63 individualsS^AS^B ⇒ 0.48 x 175 = 84 individualsS^BS^B ⇒ 0.16 x 175 = 28 individualsYou can learn more about the Hardy-Weinberg equilibrium at

What is the trend in humans as it relates to skin color?
Answer:
As a species, humans exhibit a wide range of skin colors that vary across different regions of the world. Skin color is primarily determined by the amount of melanin produced by melanocytes in the skin, which is influenced by genetic and environmental factors. There is no one-size-fits-all trend in humans as it relates to skin color, but generally speaking, skin color tends to be darker in populations that live closer to the equator, where there is more intense sunlight and a greater need for protection against UV radiation. In contrast, skin color tends to be lighter in populations that live further away from the equator, where there is less intense sunlight and a greater need for the skin to produce vitamin D. It is important to note, however, that skin color is a complex and multifactorial trait that is influenced by many factors, including evolutionary history, genetic variation, and cultural and social factors.
Humans as a species display a wide variety of skin tones that differ between various geographical locations. The amount of melanin that the skin's melanocytes make, which is influenced by both genetic and environmental factors, is what mainly determines skin color. There is no universal human tendency when it comes to skin tone, but in general, populations that are closer to the equator tend to have darker skin because there is a greater need for protection from UV rays and more intense sunlight. People who live farther from the equator, where there is less intense sunlight and a greater need for the skin to make vitamin D, have lighter skin on average.

Is it the paternal or maternal gamete that determines sex? Explain
Answer:
Sex of the baby is determined by the paternal gamete
Explanation:
Sex of the baby is determined at the time of fertilization as during this time the sperm from the male and the ovum from the female fuse with each other.
Women are homogametic and produce one type of ovum (maternal gamete) (22+X).
However the male companion is heterogametic and produces two types of sperm (paternal gamete) i.e. one 22+X and the other 22+Y in identical amounts.
Therefore the zygote would be off (44+XX or 44+XY) chromosomes depending on which kind of sperm fertilizes the ovum.
The zygote carrying 44+XX chromosomes would be a male baby whereas the other carrying 44+XY would be a female baby.
Therefore the sex of the baby is determined by the paternal gamete and not by the maternal gamete at the time of fertilization.
The mother gives an X chromosome to the child. The father may contribute an X or a Y. The chromosome from the father determines if the baby is born as male or female.
