It is neural tissue that contains large numbers of myelinated and unmyelinated axons. It contains the axons of motor neurons that extend into the periphery. It is neural tissue that contains the cell bodies of sensory neurons whose axons carry information to the spinal cord.
Answer:
It is neural tissue that is dominated by the cell bodies of neurons, neuroglia, and unmyelinated axons, and surrounds the narrow central canal.
Explanation:
Grey matter is a part of the central nervous system that is found on the surface of the brain.
It is a neural tissues that has alot of cell bodies of neurons, neuroglia and contain more unmyelinated axons and surronds the narrow central canal.it is distinguished from white matter because it has alot of cell bodies and unmyelinated axons and also it is not as white as white matter with greyish color.
Grey matter form spinal tracts which are the pathways where signals are sent from the brain to all part of the body.
Both the full body plate type and the half body plate trait are also present in an ocean near the lake. Where would you expect a higher occurrence of the full body plate trait, in the lake or the ocean? Explain your answer.
Answer:
In the ocean
Explanation:
Ecological divergence leads to selection of essential traits against migrants and hybrid species. The full body plate type traits requires attention for occurrence in an environment which is free from issues such as resource limitation or predator attacks. In vast ocean spaces , resources are not a limiting factor in ocean and also there is no risk of predators as there is huge chunk of space, thus, full body plate type will occur in higher number in the ocean.
hope it helps you..
The place where there would be a higher occurrence of the full body plate trait would be:
In the ocean
Based on the given question, we can see that when the ecological divergence which helps the full body plate type to have a higher occurrence in the lake because there is a need for attention.
With this in mind, we can see that in the ocean, there is the higher chance for the full body plate because of the absence of predators and the abundance of resources in the ocean.

Which best describes what happens if two waves meet and build on each other?
A. constructive interference
B. destructive interference
C. reflection
D. absorption
Answer:
constructive interference
Explanation:
when two waves build off of each other, they interfere with one another and construct. therefore, the answer is constructive interference.
When the path difference between subsequent crystal planes is equal to an integral number of electromagnetic radiation wavelengths, constructive interference occurs. Thus, option A is correct.
What is the constructive interference?Where the lines (which represent the peaks) cross over one another, constructive interference occurs. In other words, constructive interference occurs when two waves are in phase.
When two waves are entirely out of phase (a peak is located in the middle of two waves), destructive interference ensues.
Constructive interference is the phenomenon where the total amplitude of two waves is equal to the sum of the amplitudes of the separate waves when two waves are in phase and their maxima add.
Therefore, constructive interference best describes what happens if two waves meet and build on each other.

Unselected Remarkably efficient alveolar macrophages crawl freely along the internal and external alveolar surfaces. Unselected Huge numbers of infectious microorganisms are continuously carried into the alveoli.
Answer:
Remarkably efficient alveolar macrophages crawl freely along the internal and external alveolar surfaces
Explanation:
The alveolar macrophages are present on the internal lumenal surfaces of the alveolar ducts, the alveoli, and the bronchioles.
Alveolar macrophages are phagocytes that uses several surface receptors to release many secretions, to interact with other cells and molecules.
But the alveolar macrophages are intact to the inner surface only and do not crawl freely along the internal and external alveolar surfaces.

Why is the citric acid cycle a cyclic pathway rather than a linear pathway?
In the oxidation of pyruvate to acetyl CoA, one carbon atom is released as CO2. However, the oxidation of the remaining two carbon atoms—in acetate—to CO2 requires a complex, eight-step pathway—the citric acid cycle. Consider four possible explanations for why the last two carbons in acetate are converted to CO2 in a complex cyclic pathway rather than through a simple, linear reaction.
Use your knowledge of the first three stages of cellular respiration to determine which explanation is correct.
The given question is incomplete as the four possible explanations or options are not provided, however, the correct options are as follows:
A) More ATP is produced per CO2 released in cyclic processes than in linear processes.
B) It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA.
C) Redox reactions that simultaneously produce CO2 and NADH occur only in cyclic processes.
D) Cyclic processes, such as the citric acid cycle, require a different mechanism of ATP synthesis than linear processes, such as glycolysis.
Answer:
The correct answer would be - option B
Explanation:
Circular pathways or the cycles are able to carry out two or more than two entry and exit points for the substrate enzyme and products, So it is well suited for amphibolic reactions.
In a linear pathway, one reaction with particular substrate or reactants and result in products through the pathway completes the pathway, and the second reaction would be an independent event.
In citric acid cycle It is easier to eliminate electrons and gain carbon dioxide from compounds with 3 carbon or more carbon atoms than from a two-carbon compound such as acetyl CoA. pyruvate is 3 C compound while acetyl CoA is two carbon.
Thus, the correct answer is - option B

The given question is incomplete, the complete question is:
Madison lives near the ocean. She’s formed a hypothesis that increased concentrations of salt in the air speeds the corrosion of certain metals. If Madison plans to test this hypothesis, she will have to deal with the following variables in her experiment: dependent variable: independent variable: one possible confounding variable:
Answer:
A variable, which is under study or observation in an experiment and changes concerning the independent variable is termed as a dependent variable. Based on the given experiment, Madison is checking the influence on the progression of corrosion of metals concerning the variations in the concentration of salt. This shows that the extent of corrosion of metals is a dependent variable.
A variable, which can be controlled or monitored like increased or decreased, and one is familiar with is termed as an independent variable. This variable is not affected by another variable, like a change in the concentration of salt is the air may exhibit an effect on the corrosion of the metal, however, the process that is, the corrosion of metals does not affect the concentration of salt in the air. Hence, the independent variable is the salt concentration in air.
A variable that possesses the tendency to change or influence both the independent and dependent variables is known as a confounding variable. If the airspeed is higher than it will carry the salt particles at a brisk rate and speed resulting in enhanced corrosion of metals. Likewise, if the speed of air is slower, there will be a reduction in the corrosion of metals. Hence, the confounding variable is the speed of air.
