1.) The Addition Rule: P(A or B) = P(A) + P(B) - P(A and B)
If A and B cannot occur together, then the third term is 0, and the rule reduces to P(A or B) = P(A) + P(B). For example, you can't flip a coin and have it come up both heads and tails on one toss.
2.) The Multiplication Rule: P(A and B) = P(A) * P(B|A) or P(B) * P(A|B)
If A and B are independent events, we can reduce the formula to P(A and B) = P(A) * P(B). The term independent refers to any event whose outcome is not affected by the outcome of another event. For instance, consider the second of two coin flips, which still has a .50 (50%) probability of landing heads, regardless of what came up on the first flip. What is the probability that, during the two coin flips, you come up with tails on the first flip and heads on the second flip.
Let's perform the calculations: P = P(tails) * P(heads) = (0.5) * (0.5) = 0.25
3.) The Complement Rule: P(not A) = 1 - P(A)
Do you see why the complement rule can also be thought of as the subtraction rule? This rule builds upon the mutually exclusive nature of P(A) and P(not A). These two events can never occur together, but one of them always has to occur. Therefore P(A) + P(not A) = 1. For example, if the weatherman says there is a 0.3 chance of rain tomorrow, let's see the chances of no rain.
P(no rain) = 1 - P(rain) = 1 - 0.3 = 0.7
The rules apply to genetics because they are used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases.
Rules of probability -
Probability Rule One (For any event A, 0 ≤ P(A) ≤ 1)
Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)
Probability Rule Three (The Complement Rule)
Probabilities Involving Multiple Events.
Probability Rule Four (Addition Rule for Disjoint Events)
Finding P(A and B) using Logic.
Explanation -
Probabilities predict the likelihood that certain events will occur such as the inheritance of a particular trait in an organism. ... It can also help to predict patterns of inheritance of traits and diseases in family lines.

Answer:SECOND ONE
Explanation:

The Earth systems that interacted to cause climate changes such as an increase in temperature and a decrease in rainfall due to deforestation are the biosphere, atmosphere, and hydrosphere.
Explanation:The interaction of Earth's systems in this scenario involves the biosphere, atmosphere, and hydrosphere. When humans cut down trees, which are part of the biosphere, there is a decrease in the amount of carbon dioxide that is absorbed, leading to higher levels of this greenhouse gas in the atmosphere. This exacerbates the greenhouse effect, which increases Earth's temperature. Furthermore, trees contribute to the water cycle which affects the hydrosphere by releasing water vapor into the atmosphere during transpiration, helping to regulate rainfall. Without trees, this process is hampered, potentially decreasing rainfall in the region.

Changes in wind strength during an El Niño affect surface currents, which affects weather patterns. In 3–5 sentences, explain why this is the case.
Answer:
El Niño is defined as an unusual weather pattern seen in the Pacific Ocean. In this weather unusual winds allows the surface water to get warm from the equator to move east, that is toward Central and South America.
So, El Niño affects wind shear, in which air current present in lower altitude moves to different direction from winds higher in the atmosphere and affects weather patterns. such as El Niño is responsble for more rain in South and Central America and in the United States.

In the reaction below, what is the product?
Catechol + O2 + Catechol Oxidase ------> Hydroxyquinone + H2O + catechol oxidase
a) Catechol
b) O2
c) Catechol oxidase
d) Hydroxyquinone
Final answer:
In the reaction provided, catechol is oxidized by O₂ in the presence of catechol oxidase to produce hydroxyquinone, making hydroxyquinone the correct product.
Explanation:
In the given reaction, catechol reacts with O₂ in the presence of catechol oxidase to produce hydroxyquinone, H₂O, and catechol oxidase. Thus, the correct product of this reaction is hydroxyquinone. This reaction is an example of enzymatic oxidation, where catechol oxidase acts as a catalyst in the oxidation of catechol to hydroxyquinone, incorporating both atoms of oxygen from atmospheric oxygen (O₂) into the product. Such oxidation reactions are significant in biochemistry and organic chemistry as they involve the transformation of phenols into quinones, a process that is facilitated by enzymes in biological systems and can also be achieved chemically.

Explain how birth rate, immigration, death rate, and emigration affect population growth
Population growth is determined by the interplay of birth rates, death rates, immigration, and emigration. These factors are synthesized into a growth rate equation, indicating how each contributes to the overall population change. Demographic transition further affects these rates and, consequently, population size and growth rate.
The population growth rate is the measure of how fast a population size changes over time, and it's influenced by four main factors: birth rate, death rate, immigration, and emigration. The birth rate adds to the population when it exceeds the death rate, while the death rate reduces the population when it is higher than the birth rate. Immigration adds individuals to a population as they move into an area, while emigration removes individuals when they leave an area. The population's growth rate can be summarized by the equation: r = (b + i) - (d + e), with 'r' representing the growth rate, 'b' the birth rate, 'i' the immigration rate, 'd' the death rate, and 'e' the emigration rate.
If a country progresses through the stages of the demographic transition model, we would typically see the birth and death rates high in the early stages, leading to rapid population growth. As the country develops, the death rate tends to decline first, followed by a decline in the birth rate. As a result, the population growth rate often slows down, and the population size may stabilize or even shrink if deaths exceed births and emigration is higher than immigration.
If each dominant allele adds 10 cm to an adult humans hieght which of the following genotypes would produce the tallest adult?
AaBbCc
AaBbcc
AABbCC
Answer:
AABbCC
Explanation:
Has the most dominant genotypes out of all of them. The first one is fully compromised of heterozygous genotypes, and the second one contains a homozygous recessive genotype.
If each dominant allele adds 10 cm to an adult humans height the genotype that would produce the tallest adult is AABbCC.
What is an allele ?The term allele denotes the variant of a given gene. An allele can either be a dominant allele or a recessive allele. The dominant allele masks the effect of the recessive allele.
What is a genotype ?The genotype of an organism is its complete set of genetic material.
Since each dominant allele adds 10 cm to human height, therefore the genotype AABbCC has maximum dominant alleles (5). Hence, it will add 50 cm to the height.

2. Explain how batural selection might have produced the modern giraffe from short-necked ancestors.
Answer:
Natural selection means survival of the fittest, or the most fit animals for an environment. The most fit animals tend to thrive in their environment better than less fit animals. In this case, a short-neck Giraffe will not be able to reach leaves {its source of food}, causing it to be hungry and unable to eat. Over time, Giraffe's formed longer necks to be able to read tree leaves, making them more fit to survive.

What would happen if the hormone levels did not have their peak just before
day 14?
A. Undeveloped eggs would not start to mature.
O
B. Ovulation would not happen.
O
C. The egg would attach to the uterine wall.
O
D. The woman would become pregnant.
Without the peak of hormones around day 14 of the menstrual cycle, ovulation wouldn't occur as this process is triggered by the rise in specific hormones. As a result, it would prohibit the release of a mature egg for potential fertilization.
Explanation:The context of this question is related to the female menstrual cycle. Hormones play a vital role in regulating this cycle. Around day 14 of a typical 28-day menstrual cycle, levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) peak to stimulate ovulation, which is the release of a mature egg from the ovary. If these hormone levels did not reach their peak, ovulation would not occur. Therefore, option B, 'Ovulation would not happen', appears to be the correct answer. It's essential to note that without ovulation, pregnancy is not possible because there is no egg for sperm to fertilize.
