Answer:
the population has a Hardy-Weinberg equilibrium
Explanation:
According to the case and the information given, the genotype frequencies are:
EE (p2) = 0.61
Ee (2pq) = 0.26
ee (q2) = 0.13
To obtain the allele frequencies we can perform the following equation
Frequency of E = p = p2 + 1/2 (2pq) = 0.61 + 1/2 (0.26) = 0.61+ 0.13 = 0.74
replacing the data we obtain:
Frequency of e = q = 1- p = 1 - 0.74 = 0.26
Regarding the expected frequencies of the genotype, taking into account that there is a Hardy-Weinberg equilibrium:
EE (p2) = (0.74) 2 = 0.547
Ee (2pq) = 2 × (0.74) (0.26) = 0.384
ee (q2) = (0.26) 2 = 0.067
We know that: (p² + 2pq + q² = 1)
replacing with the obtained data:
0.547 + 0.384 + 0.067 = 0.998 ~ 1
finally we can affirm that the population has a Hardy-Weinberg equilibrium

Which of the following is the best definition of the term genotype?
A genotype is a feature in the genes. I know this since a pheno is a physical trait while geno meaning gene is a trait in the genes that can't be seen.
The genotype refers to an organism's entire genetic makeup, including all of its inherited genes.
What is a genotype?It represents the underlying genetic information that determines the traits and characteristics an organism will have, such as eye color, height, and susceptibility to certain diseases.
The genotype is influenced by the combination of genes passed down from parents and can also be affected by mutations or changes in the DNA sequence. The genotype serves as the blueprint for an organism's development and can impact its phenotype, or observable traits and characteristics.

Explanation:
give one reason mendel chose pea plants for his experiment .
Answer:
-Pea plants reproduce sexually
-Male and female sex cells on pea plants allowed Mendel to cross pollinate them
-Pea plants have a variety of traits
Explanation:
which of the following words best matches this definition: The process in which the best adapted organisms survive and pass on their traits, while those that are NOT well adapted do not survive.
Answer:
Survival of the fittest
Explanation:
According to the Darwin’s theory of survival, a species can survive among its peers only when it is fit enough to adapt to the natural changes and hence remain alive till its reproductive stage in order to produce fertile offspring.
Such species which survive are known as fit species while the remaining unable to cope with changing environment die out at an early stage of life.
Determine whether each characteristic describes a nonvascular plant or a vascular plant.
are small when fully grown
are always seedless
can be large when fully grown
normally live in moist environments
may have seeds
can live farther from water
Answer:
Vascular plants:
Can be large when fully grown.
May have seeds.
Can live farther from water.
Nonvascular plants:
Are small when fully grown.
Are always seedless.
Normally live in moist environments.
Explanation:
Plants can be classified regarding their flowering and their vasculature. When taking vasculature into consideration, they can be classified as Vascular Plants or Nonvascular plants.
Vascular plants have separate tubular tissues that are used to transport food and water, while nonvascular plants do not have these tissues. For this reason, nonvascular plants have a much harder time controlling the water inside them, and that's why they need to live in humid environments in order to survive. Vascular plants, on the other hand, can live in places farther from water.
Since they do not have vasculature, nonvascular plants are short in length, which makes it easier to survive considering the lack of tubular structures made for transport that vascular plants have.
Nonvascular plants do not have a vasculature, which means they do not have roots, stems, leaves nor seeds.

Answer:
1. perception
2. perception
3. sensation
4. sensation
5. sensation
6. perception
7. perception
8. perception
9. sensation
10. perception
Explanation:
Sensation and perception are two processes which look very similar to each other but are a different process.
Sensation involves the sensory organs of the body which can sense the physical world around us whereas perception involves the process which involves the brain as it organizes and interprets the sensory input.
1. perception- Taste is considered the perception because the taste is interpreted in the brain.
2. perception- the sensory receptors send the signals about roughness to the brain where the brain tells that the substance has roughness.
3. sensation- playing a song in the grocery store is an example of sensation as the person has just listened to the music and is not interpreting whether it is good or bad.
4. sensation- smell involves the sensory receptors but the taste of the smell is perception therefore is the smell is considered a sensation.
5. sensation- the smell is sensation therefore sensation is correct.
6. perception- perception involves the memory, experience and emotions therefore recognizing Bob is considered perception.
7. perception- reminding of soup involves memory, therefore, is considered perception.
8. perception-loud sound involves the brain, therefore, is a perception
9. sensation-feel of cloth is by sensory receptors but the type of feel will be perception.
10. perception-colour and shape are recognised by the brain and depends on memory, therefore, are perception.
This Pedigree represents a family with an Autosomal Recessive Disorder. What is the probability that IV4 and IV5 have a child with the trait?
As this family has an Autosomal Recessive Disorder, we must know that this disorder will only be expressed, in the family members who are homozygous recessive (aa), in this way, to know the probability of IV-4 and IV-5 to present the disorder, we must evaluate the probabilities of combinations of their parents' alleles in a diagram called a punnett square.
In the pedigree above, we can see that the dark colored balls and squares represent the members of the family who have the disorder and therefore have the "aa" genotype.
Thus, when observing the crossings throughout the family, we know that the father of IV-4, has the genotype "Aa", however we do not know which genotype of the mother of IV-4, but as she does not have the disorder, she may have the genotype "Aa", or "AA", for that reason, we must make the punnett square for both situations and see what the probabilities of IV-4 will present the disorder.
As you can see in the figure attached below, if IV-4's mother has the "Aa" genotype, IV-4 will have a 25% chance of presenting the disorder. If IV-4's mother has the "AA" genotype, IV-4 has a 0% chance of inheriting the disorder.
In the case of IV-5, we can see that his mother has the disorder and therefore has the genotype "aa", we know that his father does not have the disorder, but we do not know if the father's genotype is "AA" or "Aa "and therefore we must evaluate both situations.
As you can see in the figure below called "IV-5", if IV-5's father has the "AA" genotype, IV-5 will have a 0% chance of inheriting the disorder. However, if IV-5's father has the "aa" genotype, IV-5 will have a 50% chance of inheriting the disorder.

Which statement regarding lung cancer is correct?
A. Individuals with emphysema are not at risk for lung cancer.
B. Lung cancers are not aggressive.
C. More Americans die from lung cancer than any other form of cancer.
D. Only smokers will develop lung cancer.
Answer:
The correct answer is: C. More Americans die from lung cancer than any other form of cancer.
Explanation:
Lung cancer is one of the most aggressive cancers in the world, and is also the cancer that kills the most people in America every year (it is estimated that almost 140,000 Americans die from this cancer every year).
Emphysema is a chronic pulmonary disease that occurs when the air sacs in the lungs, called alveoli, enlarge and get damaged. This condition is mostly caused by smoking, and makes up a very significant risk factor for lung cancer.
Even when smoking makes up a huge risk factor for developing this and other types of cancer, non-smokers can develop lung cancer as well.
Answer: A is wrong, emphysema is not a risk factor for lung cancer. Lung cancer is primarily due to exposure to tobacco smoke and carcinogens in the smoke. Emphysema is due to loss of alveolar surface areas due to destruction of alveolar surfaces.The results is loss enough surface area for oxygen and C02 exchange in the lungs.
Generally D is wrong lung cancer is not limited to smokers only, smoking just increases it risk. Passive smokers can also develop cancer.But 45-50 of lung cancers is due to smoking. Beneze inhale from rubber industries,and asbestos industries are other places where Lung cancer can be developed after exposure.
A type of lung cancer can be agressive.(SCLC) While others can be slow.
C is correct.
Thus A is Odd
Explanation:
A student plays football outside on a hot day and lost a significant amount of water in sweat. How will this affect his blood volume?
A.Blood volume decreases
B. Blood volume stays the same
C. Blood volume increases
Answer:
A.Blood volume decreases
Explanation:
Blood volume refers to the fluid substances including blood circulating in the body via blood vessels. The blood volume must be optimal in order to ensure that every organ in the body gets an ample amount of blood. One of the things that can result in alteration of the normal blood volume is DEHYDRATION, which is the loss of water from the body.
Dehydration decreases the blood volume because the water content in the blood becomes decreased as water is lost, which would have detrimental effects on the body because the blood pressure (force at which blood flows) will be reduced.
This is the case of the student in this question that loses a significant amount of water as sweat when he undergoes exercise in a hot weather condition. The loss of water will result in the decrement of his blood volume.

How do organims form carbon films
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
Explanation:
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
When an organism is covered by sediment, it begins to decay. When decaying, the organisms release a gas. This process in turns leaves a thin film of carbon that preserves parts of the organisms.
