In humans, the ABO blood type is under the control of autosomal multiple alleles.Color blindness is a recessive X-linked trait.Mom is type A and has normal color vision.Dad is type A and has normal vision.They have a son who is type O and is color-blind.What is the probability that their next child will be a daughter who is type O and has normal color vision?Enter your answer as a fraction (for example: 1/5).

Answers

Answer 1

Answer: 1/4

Explanation:

Firstly, in order for both parents to be type A and have children with type o blood, their blood types must both be Ao. Since o is a recessive blood type, a punnett square shows there is a 25% chance any child of theirs will have type o blood. If neither parent is color blind and they have a son who is, it implies that the mother is a carrier of colorblindness and has the genotype XᴮXᵇ. If you do a punnett square of the not colorblind father (XᴮY) and the mother, it shows that a daughter would have a 0% chance of being colorblind. Therefore colorblindess is irrelevent, since there is no possibility of the daughter not having normal color vision. In conclusion, there's a 25% chance she will have type o blood and not be colorblind, since the other 75% chance would be having type A blood and not being colorblind.

Which solubility graph correctly depicts the increase of solubility associated with an increase of temperature of the solution?

Answers

In the given graphs, graph A shows the increase of solubility associated with an increase in the temperature of the solution, showing as solubility increases when the temperature increases.

What is the relationship between solubility and temperature?

A solubility curve is a line drawn on a graph to depict the relationship between temperature and a substance's solubility at various temperatures. The solubility curve is a graph showing the relationship between solubility and temperature.

Most solid or liquid solutes become more soluble with rising temperatures. In many cases, fractional crystallization, which divides compounds according to their solubilities, can separate the constituents of a mixture. A gas becomes less soluble as the temperature rises.

Therefore, in the graph, A solubility increases as temperature increases.

Explanation:

In Julius Caesar, Act II is rife with supernatural events. The night before Caesar's assassination, strange occurrences break out in Rome. A terrible storm shakes the city; warriors do battle upon the clouds; blood rains down on Rome; a lioness gives birth in the city streets; graves have opened up and "yielded up their dead." Ghosts have appeared to "shriek and squeal about the streets." Calpurnia is terrified by these supernatural events, seeing them as signs that Caesar is headed for destruction. She tells Caesar, "The heavens themselves blaze forth the death of princes." Caesar dismisses her fears and goes to the Senate where he is assassinated.

Calpurnia's strange dream may also be viewed as a supernatural event since it came true. Her dream of Caesar's statue pouring blood while Romans bathe in it becomes reality when his body bleeds from many wounds after being mortally wounded by the conspirators. They cover their arms "up to the elbows" in Caesar's blood.

Another important supernatural event occurs when the ghost of Caesar appears to Brutus in his tent before Brutus and Cassius meet Antony and Octavius in battle at Philippi. Caesar's ghost tells Brutus "thou shalt see me at Philippi." Brutus is shaken by the ghost's appearance, wanting to hear more before the ghost disappears. When no more information is forthcoming, Brutus orders that Cassius lead his forces to Philippi immediately, with Brutus to follow. Brutus will not wait for his fate to come to him. He seeks it.

Lipids in a bilayer can diffuse laterally at a relatively fast rate, but \"flip-flop\" from one leaflet to the other very slowly without catalysis. Three protein families –flippases (or flipases), floppases, and scramblases – catalyze the movement of lipids across the bilayer. Sort each of the phrases as describing flippases, floppases, or scramblases. Choose the best, most-specific enzyme name.

Explanation:

Flipases are transportes that require energy for their functioning (ATP dependent) beause they move phospolipids across the lipid bilayer against the concentration gradient (from extracellular side to cytosolic side).

Floppases are ABC transporters, opposite than flippases (move phospholipids from the cytosolic side).

Scrablases are bidirectional transporters, responsible for asymmetry formation. It also enables exposure of phosphatidylserineon the outer leaflet when it is necessary.

Food chains are usually short mainly because A) only a single species of herbivore feeds on each plant species. B) local extinction of a species causes the extinction of the other species in its food chain. C) most of the energy in a trophic level is lost as it passes to the next higher level. D) predator species are less diverse and less abundant than prey species. E) most producers are inedible.

Answers

Answer:a

Explanation:because the other ones don’t make sense

Final answer:

The primary reason for the brevity of food chains is due to substantial energy loss at each trophic level. This energy loss limits the number of viable trophic levels within a given food chain, making them usually short. Food webs better illustrate this complexity, as they factor in organisms feeding on multiple trophic levels.

Explanation:

Food chains are often limited in length due to the loss of energy at each trophic level. In essence, most of the energy within a given tier is lost as it moves to the next higher level, which is a consequence of the second law of thermodynamics. So, essentially, after several trophic energy transfers, the quantity of energy left might not be sufficient to sustain viable populations at an even higher trophic level, making food chains usually short. This is evident in the complexity of food webs, where organisms feed on or can be fed on from multiple trophic levels, creating a complex network of energy transfers that isn't purely linear like a food chain.

For example, in a typical food chain, primary producers like plants generate energy via photosynthesis. Herbivores, or primary consumers, then eat these plants, and carnivores, or secondary consumers, eat the herbivores. Each time energy is transferred to the next level, a significant portion is lost, primarily as heat, limiting the number of viable levels in the food chain.

The three-dimensional structures of tRNAs are highly conserved for what reason?The reason is probably so that each can fit equally well onto the ribosome and carry out its functionThe binding site on the ribosomes defines the order of tRNA binding, so there is no need for tRNAs to show any structural variation.The presence of different amino acids on the acceptor stem provides any necessary distinguishing features.This statement is incorrect; the three dimensional structure of tRNA is not highly conserved. If it were, the ribosomes would not be able to determine the correct amino acid to accept.

Answers

Answer:

The reason is probably so that each can fit equally well onto the ribosome and carry out its function

Explanation:

The three-dimensional structure or tertiary structure of tRNAs is conserved and crucial for the interaction : it is L-shaped 3D structure that allows them to fit onto the ribosome (its P and A sites). This is important for the function of tRNA: to be link between mRNA (carries the information from DNA) and ribosome (performs protein synthesis-translation).

Answers

Answer:

The phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.

Explanation:

The law of independent assortment is Mendel's fourth postulate which states that alleles of different genes are independently of one another assorted into gametes during meiosis. So, if we observe two traits, for example pea color (gene A) and pea shape (gene B), the alleles A and a will separate independently of alleles B and b. Mendel has shown in his experiments (with dihybrids-heterozygous for both genes e.g. AaBb) that there are four different categories with the phenotypic ratio 9:3:3:1.

Dwarf mistletoes are flowering plants that grow on certain forest trees. They obtain nutrients and water from the vascular tissues of the trees. The trees derive no known benefits from the dwarf mistletoes. Which of the following best describes the interactions between dwarf mistletoes and trees? A) mutualism B) parasitism C) commensalism D) facilitation E) competition

Answers

Answer:

C) commensalism

Explanation:

Commensalism is an interaction in which one organism benefits without causing any harm to the other. The other organism derives no benefit from the relationship.

The scenario above in which the dwarf mistletoe obtains nutrients from the vascular tissues of trees is a perfect example of such a relationship.

Parasitism is similar to this but the other organism is harmed in the process.

Final answer:

The relationship between dwarf mistletoes and trees is parasitic as the mistletoes gain nutrients from the trees without providing any benefits to the trees.

Explanation:

The interaction between dwarf mistletoes and trees can best be described as B) parasitism. This is because dwarf mistletoes obtain nutrients from the trees, thereby benefiting, while the trees derive no known benefits, indicating that they might even be harmed. This is different from examples like bees and plants or mycorrhizal relationships in plants and fungi, which represent mutualistic relationships where both parties benefit.
