A person with brown eyes has children with a person with blue eyes. The genotype of the brown eyed person is unknown;
however, it is known that brown is dominant over blue. If all of their children have brown eyes, what is most likely the
genotype of the brown eyed parent?
.
A. Bb
.
B. None of these
C.BB
D. bb
Answer:
C.
Explanation:
On the punnet square, with genotype BB, you'd be highly likely to have brown eyes unless the person with blue eyes has a dominant blue eye genotype.
A person with brown eyes has children with a person with blue eyes. If all the children are brown-eyed, that means the genotype of the parents is BB. So, the correct option is C.
What is a punnet square?
A square diagram is used to predict the genotype and thus the phenotype of the offspring when the genotype of the parents is known.
In a punnet square, the gametes formed from the genotype of one parent are written across the top row and gametes formed from the genotypes of another parent are written across the left corner.
The gametes are then crossed with each other to predict the genotype and thus the phenotype of offspring.
If one parent is brown-eyed, their genotype could be either BB or Bb. If the other parent is blue-eyed, their genotype is bb.
Now if all their children are brown-eyed. The genotype of the brown-eyed parent would be BB.
If the genotype of the brown-eyed parent was Bb, there would be two offsprings with genotype Bb and two offsprings with the genotype bb.
Therefore, the correct option is C

Analyze evidence from the lesson regarding the relationship between the structures found in cells and functions carried out by cells related to protein formation and transport or the capture, storage, and usage of energy. Choose a cellular function and make a claim about how structural features of the cell support the function. Use specific examples and details to support your claim.
Answer:
This is vvv
Explanation:
One of the cellular functions is making food/creating energy. Plant cells do this the best as they have chloroplasts that can turn sunlight, water, and carbon dioxide into glucose and oxygen via photosynthesis. This glucose is then turned into usable energy when it is transported to the mitochondria where it is turned with oxygen into carbon dioxide and ATP via cellular respiration. The ATP is taken around the cell and distributed to where it is needed via the Golgi apparatus.

Why is it necessary for Vibrio vulnificus to turn on different genes when the microbe invades a human
Answer:
Please see below
Explanation:
Vibrio vulnificus is a gram negative pathogen. It is usually present at the junction between salt water and freshwater. When it invades a human, this is a new type of host for this virus, as opposed to its previous host - a shellfish. So in order to survive and reproduce inside of the human host, it must activate the genes that will enable it to do so.
What have you learn about atoms and the universe
Answer:
Atoms are the basic units of matter and the defining structure of elements. The term "atom" comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.
Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei. This all took place within the first few minutes of the universe's existence

Explanation:
What compelled the Grimms to concentrate on old German epics, tales, and literature was a belief that the most natural and pure forms of culture—those which held the community together—were linguistic and based in history. According to them, modern literature, even though it might be remarkably rich, was artificial and thus could not express the genuine essence of Volk culture that emanated naturally from experience and bound the people together. Therefore, all their efforts went toward uncovering stories from the past. –“How the Grimm Brothers Saved the Fairy Tale,” Jack Zipes What is the author’s purpose for writing the essay "How the Grimm Brothers Saved the Fairy Tale”? to entertain children with details from the Grimms’ tales to persuade adults to read and enjoy fairy tales more often to inform scholars of the ways modern literature can be artificial to inform readers of the reasons why the Grimms collected their tales
Answer:
d. to inform readers of the reasons why the Grimms collected their tales
Explanation:
To inform readers of the reasons why the Grimms collected their tales is the Grimm Brothers Saved the Fairy Tale,” Jack Zipes What is the author’s purpose for writing the essay. Hence, option D is correct.
What is the concept of the passage?The Grimm Brothers developed a system for gathering and documenting folktales. Thus, folklore studies got their start. The Grimm Brothers firmly felt that natural forms of culture are linguistic and grounded in history, which is the core theme of this extract.
It also makes reference to this, making it one of the suitable choices. They thereby preserved the mythical tale. Since the Grimm Brothers believed that old literature was the most natural and pure kind of culture and that new writing was artificial, it is clear from "Fairy Tale" why they focused on old German epics, tales, and literature rather than modern literature. Informing the reader about these causes is the text's main goal.
Thus, option D is correct.

At approximately –50 mV, _____ is reached, Gate 1 of the voltage-activated Na+ channels opens, and Na+ ions _____ the neuron due to voltage and concentration gradients.
Answer:
threshold, enter
Explanation:
Sodium channels may be defined as the integral membrane proteins which forms the ion channels. It conducts the sodium ions through the cell's plasma membrane.
These channels are said to be located in the chromosome 2 of the human a well as mouse species. Sodium channels functions to mediate the fast depolarization and it conduct the electrical impulses throughout the nerves, heart and the muscles.
The sodium channel opens when a threshold is reached at -50mV to -55 mV which causes the rapid opening of the voltage-gated sodium channels.
