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
Answers
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.

Answers
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.

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.
Answers
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.

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
Answers
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.
