When the head is tilted, what are the structures the signal passes through on its way to becoming a fully processed neural signal within the brain?
When the head is tilted, the fluid within the_____of the inner ear moves. The exact location of stimulated cells depends on the plane of movement-with each plane being represented by a different part of that structure. The movement of fluid stimulates______which transduce the signal into an electrical signal. This signal travels through the_____nerve to the____nucleus of the_____.
Answer:
The fluid within the semicircular ducts of the inner ear, that is, endolymph moves when the head is tilted. The precise position of the stimulated cells relies upon the plane of movement with each vertical or horizontal plane being signified by distinct parts of its composition. The hair cells that transduce the signal into an electrical signal get stimulated due to the movement of fluid. The conduction of this signal takes place via the auditory nerve to the cochlear nucleus of the brainstem.
Within the inner ear cochlea, the stimulation of the hair cells or stereocilia takes place by endolymph, it is a fluid present in semicircular ducts. After stimulation, the hair cells mediate electric signals to the brain via the auditory nerve, these are the nerve bundles that carry signals of sound. The initial central auditory composition found in the brainstem is the Cochlea nucleus.
Answer:
the fluid within the -semicircular canals- of the inner ear moves. the movement of the fluid stimulates the -hair cells- which transduce the signal into an electric signal. This signal travels through the -vestibulocochlear nerve- to the vestibular nucleus of the -medulla oblongata-.

Answer:
I'm pretty sure it's fish since they evolved into both reptiles and amphibians
Explanation:
The first creatures that evolved the first are fish. The first creatures they were evolved before amphibians,reptiles and mammals were fish.
What is the king organism of reptiles ?The king organism of reptiles category is crocodile.
Amphibians, reptiles, mammals and birds evolved after fish where the first amphibians that evolved from a lobe-finned fish ancestor about 365 million years ago. Fishes were the most earliest vertebrates to live on land but they had to return to water in order to reproduce.
The first vertebrates were therefore the fishes that had the different categories from chordates and vertebrates where few had the notochord and few had the vertebral columns.

Use the diagram below to help you to choose ALLL the CORRECT answers for the question: What are the differences between Meiosis i and Meiosis II?
(MULTIPLE CHOICE)
A In Metaphase I and Metaphase II the chromosomes line up differently because there are a different number of copies
B Telophase and cytokinesis do NOT happen in Meiosis II
C After Meiosis II the 4 daughter cells undergo cell specialization to become eggs or sperm, which does not happen after Meiosis I
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Answer:
D In Prophase I the chromosomes crossover, in Prophase II they do not crossover
Explanation:
Meiosis is a type of cell division in which four daughter cells, which are genetically different from one another, are produced. The daughter cells have their chromosomal number reduced by half. Since, the meiotic process aims at producing haploid gametes, it occurs in a series of two-division steps viz: meiosis I and meiosis II.
Meiosis I involves the separation of homologous chromosomes into two daughter cells while the meiosis II involves separation of chromatids to make four daughter cells. One major difference between meiosis I and meiosis II is that in the PROPHASE of meiosis I, a unique process called CROSSING OVER occurs but does not occur in meiosis II (as seen in the attached image).

Explanation:
If you fertilize your houseplant too often, you may find that it looks wilted even when the soil is wet. Explain what has happened in terms of water potential?
Answer:
Water moved out of the cells of the houseplant into the extracellular solution because they (plant cells) have a high water potential (Ψ) than the extracellular environment.
Please find the explanation below
Explanation:
In biology, water potential, denoted by Ψ, refers to the ability of water to move freely in a system. Based on this definition, a hypertonic solution (solution with higher solute concentration) will have a low Ψ while a hypotonic solution (solution with low solute concentration) will have a high Ψ.
According to this question, if a houseplant is fertilized too often, it will increase the concentration of solute in the soil (extracellular environment of the plant cells) i.e. the fertilizer will make the extracellular solution HYPERTONIC. Because the cells of the houseplant are hypotonic to the soil solution i.e. now has a high Ψ in comparison with the soil solution, water will move from the cells of the plant to the soil solution (extracellular) via the cell membrane (semi-permeable membrane) in a process called OSMOSIS.
NOTE: Water moves from a solution with high Ψ to a solution with low Ψ. This is what propels the movement of water from the cell with a high water potential to the exterior of the cell with a low water potential (caused by frequent addition of fertilizer). Overall, the houseplant will look WILTED even if the soil is wet.

1. Imagine that the class had 25% of students with free earlobes and 75% with attached earlobes. What would this suggest about the frequency of the dominant (F) and recessive (f) alleles for these traits in the class population? Explain your reasoning.
Answer:
People with free earlobes carry one or two dominant alleles which means that the free earlobe is a dominant trait over attached earlobes that carries two recessive alleles. The recessive allele is represented by f and the dominant allele is represented by F.
It is given that in a class 25% of students in the class had free earlobes which means either 25% of total alleles are FF or Ff and the rest 75% have ff. It suggests that recessive alleles have more frequency than dominant alleles.

What is plate tectonics?A uniform framework for comprehending mountain-building processes, volcanic eruptions, earthquakes, the evolution of the Earth's surface, and reconstructing the planet's former continents and oceans was provided by the plate tectonics theory, which deals with the dynamics of the lithosphere, the outer shell of the planet. This theory revolutionized Earth sciences.
In the 1960s, the theory of plate tectonics was developed. The lithosphere, which is Earth's outermost layer and is normally around 100 km (60 miles) thick, sits on top of the asthenosphere, which is malleable and partially molten. The lithosphere is divided into numerous tiny plates, six or seven medium-sized regional plates, and seven extremely massive continental and oceanic plates.
These plates interact at their borders, where they converge, diverge, or slide past one another, moving relative to one another often at speeds of 5 to 10 cm (2 to 4 inches) each year. Although earthquakes and volcanoes can occur in plate interiors, these interactions are regarded to be the main cause of the majority of Earth's seismic and volcanic activity.
Where plates press together or converge, mountains will rise, and where plates pull away or diverge, continents will split and oceans will arise. Since the continents are passively drifting with the plates over the course of millions of years, the Earth's geography has undergone enormous changes.
Therefore, this analogy is used to illustrate the movement of the plates and to assist understand it.

Explanation:
Enzymes are protein catalysts. What is the role of a catalyst?
Answer:
Enzymes are proteins functioning as catalysts that speed up reactions by lowering the activation energy. A simple and succinct definition of an enzyme is that it is a biological catalyst that accelerates a chemical reaction without altering its equilibrium.
Catalysts make such a breaking and rebuilding happen more efficiently. They do this by lowering the activation energy for the chemical reaction. Activation energy is the amount of energy needed to allow the chemical reaction to occur. The catalyst just changes the path to the new chemical partnership.
