The frequency of the allele for blood type B in a country is represented as 30 out of every 100 people. Type A’s frequency is found in 40 out of every 100 people. Given those two frequencies, what is the frequency of the recessive type O allele? Use either decimal or whole number % to answer this.
Answers
We can use the fact that the frequencies of all the alleles must add up to 1 to find the frequency of the O allele. That is:
Frequency of A allele + Frequency of B allele + Frequency of O allele = 1
Solving for the O allele frequency:
Frequency of O allele = 1 - Frequency of A allele - Frequency of B allele
Frequency of O allele = 1 - 0.40 - 0.30
Frequency of O allele = 0.30 or 30%
Therefore, the frequency of the recessive type O allele is 0.30 or 30%.

Why do teens tend to make riskier decisions than adults?
Answers
Brain Development: The brain undergoes extensive development and reorganization during adolescence, particularly in the prefrontal cortex, which is responsible for decision-making, impulse control, and weighing consequences. This region develops at a slower pace compared to the reward-seeking regions of the brain, such as the limbic system. As a result, teenagers may be more driven by immediate rewards and less inclined to consider long-term consequences.
Sensation Seeking: Adolescence is characterized by heightened sensation seeking and a desire for novel and exciting experiences. Teenagers often seek out new sensations and engage in risk-taking behaviors as a way to explore their own identity, gain independence, and test boundaries. The pursuit of thrills and excitement can overshadow the potential risks involved.
Social Influence: Peer influence plays a significant role during adolescence. Teenagers are highly attuned to social acceptance and approval, and they may engage in riskier behaviors to fit in, gain peer recognition, or conform to social norms within their peer group. The desire for social status and acceptance can override concerns about potential negative outcomes.
Incomplete Experience and Judgment: Compared to adults, teenagers have less life experience and exposure to various situations, making it more challenging for them to accurately assess risks and make informed decisions. They may lack the cognitive tools and judgment skills to fully evaluate the potential consequences of their actions.
Emotional Intensity: Adolescence is a time of heightened emotional intensity, with teenagers experiencing intense emotions and seeking ways to regulate them. Risk-taking behaviors can serve as a means to cope with or regulate these emotions, providing temporary excitement, distraction, or a sense of control

which of the following is typical correct order of floral organs from the outside to the inside of a complete flower?
Answers
sepals, petals, stamens, carpels are correct order of floral organs from the outside to the inside of a complete flower.
The four primary whorls of a typical flower are the calyx, corolla, androecium, and gynoecium. The flower's outermost whorl is composed of sepals, which are green, leafy structures. The calyx, which is made up of the sepals, serves to shield the closed bud. The corolla, or collection of petals in the second whorl, are typically brilliantly colored. Whether a plant is a monocot or a dicot affects how many sepals and petals it has. Petal counts in dicots are typically four or five, or multiples of four and five, whereas they are typically three or multiples of three in monocots.

Natural gas may also be produced from organic material at high enough pressure. The two basic factors that convert biological matter into fossil fuels are heat and pressure.
What transforms extinct animals into crude oil and natural gas?Algae and plants inhabited shallow oceans millions of years ago. The organic material was buried when it perished and sank to the bottom, where it mingled with other materials. The remnants of these animals were converted into fossil fuels over millions of years under extreme pressure and heat.
Layers of clay and sand have been covering dead creatures that were buried in the water millions of years ago. These decomposing organisms became petroleum and natural gas as a result of the lack of air, the high temperature, and the high pressure.

The allele for a widows peak hairline is recessive. Mulan has a widow’s peak. Both of her parents have widow’s peaks. What is the probability for Mika to have a widow’s peak. Create a Punnett Square.
Answers
The probability for Mika to have a widow’s peak is 100% or 1.0. The Punnett square is in the image attached.
How to create a Punnett square?Assuming that the genotype for the widow's peak allele is "W" and the genotype for the non-widow's peak allele is "w", we can represent the genotypes of Mulan's parents as WW and Ww, since both have widow's peaks.
To create a Punnett Square, list the possible gametes that each parent can produce along the top and left side of the square, and then fill in the boxes with the resulting genotypes of their offspring:
| W | w
--|----|---
W | WW | Ww
--|----|---
W | WW | Ww
Each box represents a possible offspring genotype. The probabilities for each genotype can be calculated by counting the number of boxes with that genotype and dividing by the total number of boxes.
In this case, there are four possible genotypes for the offspring: WW, Ww, wW, and ww. The first three genotypes all result in a widow's peak, while the fourth genotype results in a non-widow's peak.
Counting the boxes, we see that there are 2 boxes with the WW genotype, 2 boxes with the Ww genotype, and 0 boxes with the wW genotype or ww genotype. This means that the probability of Mika inheriting a widow's peak is 100%, or 1.0.

What is the trend in humans as it relates to skin color?
Answers
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.
