Scientists once thought that life spontaneously arose from nonliving things. It took extensive experimentation and the invention of new technology to confirm the tenets that now make up the cell theory. Now, we don't even question that cells are the basic units of life and only come from preexisting cells. What technology had the biggest impact on the development of the cell theory?
A) centrifuge
B) electrophoresis
C) microscope
D) telescope
Answer:
Microscope.
Explanation:
Microscopes were extremely influential in the development of cell theory, as they allow us to see down to the level of cells and observe them. Through process of elimination, we know it cannot be a telescope (used for observing large, far away objects) or a centrifuge (separates substances based on density). Electrophoresis is moreso used for DNA, and not for the entire cells.
In a study of the Hopi, a Native American tribe of central Arizona, Woolf and Dukepoo (1959) found 26 albino individuals in a total population of 6000. This form of albinism is controlled by a single gene with two alleles: albinism is recessive to normal skin coloration. Calculate the expected allele frequencies and genotype frequencies if the population were in Hardy-Weinberg equilibrium. What is the allele frequency of the normal allele
Answer:
0.9342
Explanation:
The Hardy-Weinberg equation states that p² + 2pq + q² = 1,
where p is the frequency of the dominant 'normal' (n) allele and q is the frequency of the recessive 'albino' (a) allele in the population, while q² represents the frequency of the homo-zygous albino genotype (aa), p² represents the frequency of the homo-zygous normal genotype (nn) and 2pq represents the frequency of the heterozygous genotype (na).
In this case, the frequency of individuals in the population that have the genotype aa (q²) is equal to 26/6000 = 0.004333. In consequence, q is equal to √ 0.004333 = 0.0658.
Moreover, the allele frequency of the normal (n) allele p is equal to 1 - q = 1 - 0.0658 = 0.9342, so p² (nn) = (0.9342)² = 0.8727.
Finally, the frequency of the heterozygous genotype (na) is 2pq = 2 x 0.9342 x 0.0658 = 0.123.
A population is a collection of all the types of organisms in an area.

A serial dilution is performed on a culture of Saccharomyces cerevisiae (Brewer's yeast). A 1:10 dilution was performed in series seven times. You plated and spread 100 microliters of the fifth dilution to a YEPD agar plate to grow overnight. After incubation, you count 142 colonies on the plate. What was the viable count of the stock culture
Answer: CFU/mL = 14200 CFU/mL
Explanation:
Microorganisms are very small and difficult to count directly. Instead, a laboratory technique is used to count CFUs (Colony Formation Units). This involves making dilutions of a microbial suspension and spreading it on thin layers of agar containing nutrients for growth in Petri dishes also called agar plates. After incubation under ideal conditions, some plates are completely covered with microbial growth; some have little or no growth; and some are covered with individual isolated "spots", which are microbial colonies. Since a colony may consist of a single organism or a group of microbes, the dots represent a CFU.
To calculate the viable count of the stock culture, you have to count the number of colonies, multiply by the dilution and the result will be the plate count in CFU.
So, the equation is:
CFU/mL = Number of colonies / (Volume trasferred to plate x dilution blank)
100 microliters = 0.1 mililiter
1/10 = 0.1 (dilution factor)
Replacing the information from the question:
CFU/mL = 142 / (0.1 mL x 0.1)
CFU/mL = 14200 CFU/mL

Please help.What would you expect to occur if you were to repeatedly lift 25 pounds over your head for 1 minute,
rest for 1 minute, and then repeat the exercise? Why do you expect this outcome?
Answer:
Strengthen the arms.
Explanation:
If a person repeatedly lift 25 pounds of weight over the head for 1 minute and then rest for 1 minute, the outcome of this exercise is to strengthen the muscles of the arms. The lifting of weight with the help of arms, the muscles of the arms will get stronger and increase occurs in the width of the arms. This exercise done by bodybuilders to get their arms stronger as well as athlete for stronger arms and hand muscles so the outcome of lifting the weight will leads to the increase in the strength of the arms.

Is a plant that has the natural ability to protect itself against predation a genetically engineered organism
Answer:
No, genetically engineered organisms are engineered by humans. The plant evolved to be this way.
Explanation:
Answer:
If it's a natural ability for the plant, it's probably not genetically engineered. It depends on the plant species/fruit.
Explanation:
Predation: A biological interaction where one organism, the predator, kills and eats another organism, its prey.
Genetically Engineered Organism: An animal, plant, or microbe whose DNA has been altered using genetic engineering techniques.
In most cases with let's say a pepper plant, the plant will produce a chemical compound called capsaicin. This is what makes the peppers spicy. It really just depends on the plant we're talking about.

O 2, 4, and 5
O 1, 4, and 6
O2, 3, and 5
O 1, 3, and 6
The correct option is D.) 1, 3, and 6 because pressure is the changing factor in Gay-Lussac's Law, the constant factor in Boyle's Law, and the changing factor in Charles's Law.
Gay-Lussac's Law states that the pressure of a given quantity of gas held at constant volume is directly proportional to the Kelvin temperature which means the pressure of a gas increases as the temperature increases, and decreases as the temperature decreases.
Boyles Law states that the pressure of a gas is inversely proportional to its volume that means as the volume of a gas increases, the pressure of the gas decreases, and vice versa.
Charles's law is a basic physical law that states that the volume of a given amount of gas at a constant pressure is directly proportional to its absolute temperature. This means that when the temperature of a gas increases, its volume also increases, and vice versa.

Indicate whether the statements below are TRUE or FALSE.
1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.
2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.
3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.

Which statement correctly describes how the mitochondrial uncoupling agent valinomycin inhibits oxidative phosphorylation without collapsing the proton (H+) gradient across the inner mitochondrial membrane?
a. Valinomycin carries Kt into the mitochondrial matrix, reducing the electrical component of the electrochemical gradient across the inner mitochondrial membrane.
b. Valinomycin carries Ht into the mitochondrial matrix, decreasing the mitochondrial membrane potential without generating ATP.
c. Valinomycin is a complex I inhibitor that prevents NADH oxidation and the pumping of H+ into the intermembrane space.
d. Valinomycin is an ATP synthase inhibitor that prevents H+ from moving down its concentration gradient into the matrix.
Answer:
a. Valinomycin carries Kt into the mitochondrial matrix, reducing the electrical component of the electrochemical gradient across the inner mitochondrial membrane.
Explanation:
Oxidative phosphorylation is a process by which cells generate ATP (the energy coin of the cells) by coupling an electrochemical potential gradient across the inner mitochondrial membrane created by the electron transport chain to phosphorylation of ADP. Moreover, an ionophore is a molecule that reversibly binds ions. Ionophores are often involved in the movement of ions across the cell membrane. Valinomycin is an ionophore that mediates the transport of potassium (K+) ions down a concentration gradient, which is capable of disrupting the gradient across the membrane by modifying the K+ gradient. Valinomycin binds to K+ ions and enables them to pass more rapidly across the mitochondrial inner membrane, thereby neutralizing the excess of negative charge inside the mitochondrial matrix and thus slowing ATP synthesis.
