Primary sensory areas of the brain have connections to association areas. What are the names, locations, and functions of the association areas for sight, hearing, and touch
Answer:
There is no short answer.
Explanation:
Association areas are mostly located in the cerebral cortex and they process the information coming from the sensory areas such as hearing, vision etc.
The association area for sight is located in the occipital lobe and it's name is striate cortex. It's main function is to process the signals coming from the eye.
The association area for hearing is located in the temporal lobe and it's main function is to process the information coming from the ears.
The association area for touch or the sensory association area is located in the cerebral cortex and it's main function is to process the signals coming from the sensory stimuli outside the body.

You want to know if music increases productivity in the workplace. One group of employees listens to music while they work. Another group does not listen to music. Productivity is measured at the end of each month. What is the independent variable?
Answer:
The independent variable is one that is controlled to corroborate its effects or the relationship causes consequence with a phenomenon in relation to the dependent variable.
Explanation:
In an epidemiological study, or a research based on a hypothesis, there are different variables.
Variables are those phenomena that vary over time and can be quantifiable over time.
The quantification of the variables must be through indexes or analysis, and these in turn must confer data reliability.
On the other hand, there are two types of variables, dependent and independent, homogeneous or non-homogeneous (that is, they occur in one individual or in many at the same time) and if they are reasonable or not in the face of a given investigation.
If the variable that is chosen in an investigation is not reasonable or homogeneous, it will never become independent or dependent since it will not be good to take it into account or count it during the investigation.
In this case, the possible variables could be: the type of music, different levels of hearing by the workers, the type of work they do when listening to music, the volume of the music in which it is heard.
Why do you think Dr. Margulis met so much resistance with her introduction of endosymbiosis?
Answer:
Because there is scientific evidence that evolution occurs gradually and endocimbiosis is a type of evolution that occurs suddenly.
Explanation:
Although Dr. Margulis was very thorough in her defense of endosymbiosis, she had to face great resistance from the scientific community around this theory. This was because as we know, and as it is scientifically proven, evolution is something that happens gradually and slowly and that is exactly what scientists believed and defended. However, endosymbiosis presented a kind of evolution that happened abruptly and suddenly, which provoked resistance to the theory.

5. Some undiluted acids are more corrosive when diluted
with water. That is why lab workers are told to wipe off
splashes with a towel before washing. Explain.
Answer:
The correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.
Explanation:
Diluted acids are more corrosive then undiluted due to the presence of more H+ ions than the undiluted acids. The More the H+ ions are added the more corrosive the acid is.
When water is mixed with strong acid the hydrogen ions reacts with acid ions and a exothermic reaction takes place that release high amount of energy which boils violently, to avoid any accident it is advised to lab workers to wipe if any splash self before washing.
Thus, the correct answer is : due to the hydrogen ions reacts and release high amount of energy with the strong acid.
A ship is at anchor. Over its side hangs a rope ladder with rungs a foot apart. The
tide rises at the rate of 8 inches per hour. At the end of 6 hours, how much of the
rope ladder will remain above the water, assuming that 8 feet were above the
water when the tide began to rise?
Answer:
At the end of 6 hours, 6 feet of the ladder remained above water
Explanation:
we are given the following:
change in tide = 8 inches per hour
1 hour = 8 inches
∴ 6 hours = 8 × 6 = 48 inches
Now, since the length of the ladder is measured in foot, let us convert the rate of tide rising to foot.
12 inches = 1 foot
dividing both sides by 12:
[tex]1\ inch=\frac{1}{12}\ feet\\ \therefore 48\ inches\ =\ 48\ \times \frac{1}{12}\\ =\frac{48}{12}\\ = 2 feet[/tex]
Therefore, after 6 hours, the tide rises by 2 feet.
Next, we are told that the rope ladder at the beginning was 8 feet, hence the length remaining above water after 6 hours of the rising of the tide is calculated as follows:
= 8 feet above water
height of tide = 2 feet = amount submerged in water
∴ length above water = (ladder before rising of the tide) - (amount submerged in water)
length above water = 8 - 2 = 6 feet
Therefore at the end of 6 hours, 6 feet of the ladder remained above water
Sally has collected a sample of dirt from a riverbank and wants to analyze it. First she decides to find the mass of the sample. What tool should she use?
Answer:
By using s measuring cylinder
Answer:
A ,pretty sure
Explanation:
Enzymes only work with certain substrates. If a certain enzyme only works with a certain substrate, it is because the enzyme Group of answer choices has a particular shape that matches the substrate. can only reach that one substrate inside the cell. activates in response to chemicals from the substrate. is only found in organisms with that substrate.
Answer:
has a particular shape that matches the substrate
Explanation:
Enzymes are proteinous biological catalyst i.e. they speed up the rate of biochemical reactions in living systems. Like every other catalyst, enzymes reduce the activation energy of the reactions they are involved in without getting used up in the process.
Enzymes operate by binding to a substrate molecule i.e. the reactant and form a bond with them in order to synthesize a product. However, enzymes are substrate-specific i.e. they are very particular about the substrate they bind to. This property is due to the shape of the enzyme which matches a particular substrate.
Enzymes, like every other protein molecules, are made up of amino acid subunits, which are responsible for the shape that determines the specificity of the protein.

Find the weight of a pine tree that has a circumference of 14 inches and a height of 120 feet. Use the equation: W = b0 + b1(D2H)
Answer:
W = b0 + 2381 b1
Explanation:
First of all, you need to understand that in the formula shown above, the "W" represents the weight in tones. The "b0 + b1" are the constants, "D" is the diameter of the tree that must be presented in centimeters and the "H" is the height of the tree in feet.
As shown above, the circumference of the pine is 14 inches, but we know that the circumference is equal to 2πr, in this case, we will use the value 22/7.
I understand the factors above we will have the formula:
14 = 2 (7/22) × r
14 = (44/7) × r
r = 14 × 7/44 = 2.23 inches
So the diameter = 2r = 4.45 inches
Now we will replace the formula W = b0 + b1 (D2H).
W = b0 + b1 (4.45 ^ 2 * 120)
W = b0 + 2381 b1
To solve the rest we would need the values of b0 and b1, which we don't have. For that reason, the answer would be ended in this way.
how does a human and scuba gear interact
Answer:
Scuba diving is a mode of underwater diving where the diver uses a self-contained underwater breathing apparatus, or scuba gear, which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers.

At the coordinates 45 degrees W & 72 degrees N it is 9:32 AM. What time is it at the coordinates 75 degrees W & 45 degrees S? 8:32 AM, 10:32 AM, 11:32 AM, 7:32 AM
Answer:
The correct option is;
7:32 AM
Explanation:
The information given are;
The time at 45 degrees W and 72 degrees N = 9:32 AM
The variation of time with lines of longitude is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west of the initial location
Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted
The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM
The latitude of a place left out in the calculation of the relative time of a place.
The two thyroid hormones, thyroxine and triiodothyronine, have complementary effects in which they decrease the rate of cellular metabolism and oxygen consumption in almost every cell in the body.
a. True
b. False
Answer:
False
Explanation:
The thyroid gland secrete two thyroid hormones called thyroxine and triiodothyronine. Thyroxine is the in active form which is later converted to the active form triiodothyronine by kidneys and livers. The two hormones function by increasing the metabolic activities of tissues. They increase the body heat production which in turn increase oxygen consumption and ATP hydrolysis because they burn body fat thereby increasing energy production and increasing basal metabolic rate. They regulate body temperature.

The atmosphere is made up from 77 percent nitrogen (N2), 22 percent oxygen (02) and all other gases are less than one percent of the atmosphere. The crust, part of the Geosphere is made up for almost 47 percent of Oxygen. Why can’t we breathe the crust?
Answer:
Well, we can not breathe in solids. But I'm guessing that this question is more based on the type of oxygen that's in the crust.
There are oxygen ions in m=almost everything in the earths crust, yes, but we do not breathe in the same type of oxygen that is bound to their crystal structures.
There are plenty of oxygen atoms in the earth's crust, but there are very few oxygen molecules. The crust is primarily made up of silicate minerals…feldspars, pyroxenes, amphiboles, quartz, etc. There are also lots of oxide, carbonate, phosphate, and sulfate minerals. These all have large amounts of oxygen atoms tightly bound in their crystal structures. But this is not the free molecular oxygen that we breathe.
Because free oxygen molecules (O2) are very reactive, vanishingly little of it is found in the crust below the depths of shallow cool groundwater. Air, including its 20% oxygen, dissolves in rain as it falls from the sky. Some of this air-saturated water soaks into the earth and recharges the groundwater system, carrying the air with it. Nitrogen, argon, and other unreactive trace gases can be circulated quite deeply with this downflowing water…to 10km or more. However oxygen is very reactive, and so it reacts with the minerals in the rocks (or forms new minerals) before it gets transported very deep. You have probably seen evidence of this reaction in red or brown stained rocks exposed at the earth's surface that have been oxidized by downflowing surface waters.
In the geothermal industry, where wells produce deep, magmatically heated waters for power generation, we routinely see atmospheric nitrogen and argon in the produced fluids. This, along with the isotopic composition of the water, gives a clear indicator atmospheric origin of the water (most of it, at least). However there is absolutely no dissolved oxygen in those waters. It all reacted with the rock long ago.
