lue eyes (b) are recessive to brown eyes (b). in a population of swedes 64% of the individuals have blue eyes. in a population of armenians, 9% of the individuals have blue eyes. assuming that hardy-weinberg equilibrium holds for the swedish and armenian populations independently, what are the proportions of eye color genotypes in each population? show your work.
Answers
In the Swedish population, the genotype proportions are 36% BB (brown), 48% Bb (brown carriers), and 16% bb (blue). In the Armenian population, the genotype proportions are 82% BB (brown), 36% Bb (brown carriers), and 4% bb (blue).
To determine the proportions of eye color genotypes, we can use the Hardy-Weinberg equation. In the Swedish population, where 64% have blue eyes, the frequency of the recessive allele (b) can be calculated as the square root of 0.64, which is approximately 0.8. The genotype proportions are then calculated as follows: BB (brown) = (1 - 0.8)^2 = 0.36, Bb (brown carriers) = 2 * 0.8 * (1 - 0.8) = 0.48, and bb (blue) = 0.8^2 = 0.16.
Similarly, in the Armenian population, where 9% have blue eyes, the frequency of the recessive allele (b) is approximately 0.3. The genotype proportions are: BB (brown) = (1 - 0.3)^2 = 0.49, Bb (brown carriers) = 2 * 0.3 * (1 - 0.3) = 0.36, and bb (blue) = 0.3^2 = 0.09. These calculations assume that the populations are in Hardy-Weinberg equilibrium.

What is the main function of nervous tissue?
A. To cover the body to protect other cells
B. To transport materials and defend the body
C. To send signals to control the body
D. To contract to cause movement in the body
Answers
Answer:
Explanation:
To send signals to control the body
Nerve cells: Transport signals around body
Tissue: Made of many cells
The main function of nervous tissue is C. To send signals to control the body. Nervous tissue is made up of specialized cells called neurons that are capable of transmitting electrical and chemical signals throughout the body. These signals allow the nervous system to control and coordinate various body functions, including movement, sensation, and thought processes. In addition to neurons, nervous tissue also contains support cells called glial cells that help to protect and nourish the neurons. Overall, nervous tissue plays a critical role in the functioning of the nervous system and the control of bodily functions.
In photosynthesis, carbon dioxide (CO₂) and water (H₂O) combine to form the sugar glucose (C6H12O6) in the following reaction:
6CO₂ + 6H₂O → C6H12O6 + ?
Assuming this equation is balanced, which part is missing from the product side?
(1 point)
O 6 carbon atoms
O 6 oxygen atoms
O 12 hydrogen atoms
12 oxygen atoms
Answers
Answer:
Explanation:
6CO₂ + 6H₂O → C₆H₁₂O₆ + ?
To have a balanced equation there must be the same number on both sides of the equation for each type of atom.
There are 6 carbons on the left and right sides of the equation, so they are balanced.
There are 12 hydrogens on the left and right sides of the equation, so they are balanced.
There are 18 total oxygen atoms on the left side of the equation, but there are 6 oxygen atoms on the right side of the equation.
We need 12 more oxygen atoms on the right side of the equation to have a complete and balanced equation.
Add 12 more oxygen atoms in the form of 6O₂ on the right side of the equation. Now there is a total of 18 oxygen atoms on the left and right sides of the equation.
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
What is the probability that an individual is Aa or AA if his or her parents are both heterozygous for the trait?a. 1/4b. 1c. 1/2d. 3/4
Answers
The probability that an individual is Aa or AA if his or her parents are both heterozygous for the trait is d. 3/4.
To determine the probability, we can use a Punnett square to show the possible outcomes of the parents' alleles.
| A | a
--|----|--
A | AA | Aa
a | Aa | aa
As we can see from the Punnett square, there are four possible outcomes for the offspring: AA, Aa, Aa, and aa. Of these four outcomes, three of them (AA, Aa, and Aa) include at least one dominant allele (A), which means the individual will have the dominant trait.
Therefore, the probability of an individual being Aa or AA is 3 out of 4, or 3/4.

Consider an animal cell in which motor proteins in the kinetochores normally pull the chromosomes along the kinetochore microtubules during mitosis. Suppose, however, that during metaphase, this cell was treated with an inhibitor that blocks the function of the motor proteins in the kinetochore, but allows the kinetochore to remain attached to the spindle. The inhibitor has no effect on any other mitotic process, including the function of the nonkinetochore microtubules. Consider three questions concerning the animal cell that has been treated with the inhibitor. Drag the terms to answer the questions. Terms may be used once, more than once, or not at all.
Answers
1. Will this cell elongate during mitosis ? - Yes
2. Will the sister chromatids separate from each other ? - Yes
3. Will the chromosomes move to the poles of the cell ? - No
What is kinetochore ?To transport the replicated DNA from a mother cell to its daughters, large protein structures called kinetochores connect chromosomes to the microtubules of the mitotic and meiotic spindles.
A area of the mitotic chromosomes known as the "kinetochore" receives the majority of the spindle's force. This area is typically depicted as the pinnacle of the characteristically V-shaped anaphase chromosome, which points the chromosome toward the pole.

Answer:
Mouth: The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
Pharynx: It receives food and air from the mouth, and air from the nasal cavities.
Esophagus: the esophagus receives food from your mouth when you swallow.
Stomach: It takes in food from the esophagus, mixes it, breaks it down, and then passes it on to the small intestine in small portions.
Small Intestine: The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream.
Large Intestine: The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption has already taken place.
Rectum: The rectum stores the stool until you feel the need to have a bowel movement. Muscles of your rectum then push the stool through your anus and out of your body.
Anus: The anus is the opening at the far end of the digestive tract through which stool leaves the body.
Liver: Your liver makes a digestive juice called bile that helps digest fats and some vitamins. Bile ducts carry bile from your liver to your gallbladder for storage, or to the small intestine for use.
Pancreas: your pancreas makes pancreatic juices called enzymes.
Gallbladder: the bile passes to the gallbladder which concentrates and stores it for later use
Blood: blood transports nutrients and hormones

Evolution occurs when there is selection pressure for some heritable trait over a period of time.
True
False
Answers
True
Explanation
Everything is always evolving over an amount of time, for example say we had two types of rabbits, one had white fur and the other has brown. If the one that has white fur tries to live in the same habitat as the one with brown fur they will be able to be spotted easier. So the brown rabbits they have the “desirable trait” or “heretable trait” because they can hide from being hunted. Even then the brown rabbit will adapt over time, evolution is always competing, so if the brown rabbit needs to hop higher then over time the rabbits that have the strongest trait will become the new normal.
