Answer:
Your brain is a hotbed of electrochemical activity. About 100 billion neurons are each firing off 5-50 messages (action potentials) per second. This activity allows you to process your environment, move your muscles, and even keep your balance! If you touch something slimy, that information goes from your fingertips to your brain, and then your brain says “eww, no!” and sends information to your fingertips telling them to move away. The same thing happens when you trip and you’re about to fall, or a bright light flashes in your eyes. Your brain receives information about where you are in space, or the brightness of the light, and responds accordingly. And it’s in our best interests that this action-reaction process goes quickly – so that we can catch ourselves as we fall, or shut our eyes tight. The process of sending these signals takes place in two steps: along the cell (action potential) and between cells (neurotransmitters).

Which type of dating method can be used on rock layers by applying the law of superposition
Answer:
Relative dating
Explanation:
The Law of Superposition of rocks states that the layer of rock which is below is older than the one above it.
Therefore, the type of dating method that can be used on rock layers by applying the law of superposition is relative dating because it is used when the rocks have been kept in their original sequence and not tampered with.

If Adam is walking to his car in the snow and feels himself starting to slip and fall, he is using what sensory pathway to convey this information to the level of his conscious awareness?a. posterior column pathway b. corticospinal pathway c. anterior spinothalamic tract d. lateral spinothalamic tract
Answer: A (POSTERIOR COLUMN PATHWAY)
Explanation: Corticospinal pathways are involved in motor pathway whereas others are involved in sensory. however, lateral spinothalamic pathway carry sensations like pain and temperature.
But,the posterior column and the anterior spinothalamic carries the sensation of touch.
The anterior spinothalamic pathway carries light touch while the posterior column carry deep touch and sensation.
Now from the question,fall and slip vibration and movement brings about the activation of posterior column, However,it carries information to the conscious center of the cerebrum whereas the spinothalamic pathway carries information to the thalamus in the brain.

Sorry if its wrong
The food color mixes more easily with the warm water than with the cold water, as the warm water has less density than the cold water, which allows the diffusion of the color in the water.
What role does food coloring play in the lives of organisms?It has numerous negative effects on the organism, including allergic reactions to certain food coloring, increased hyperactivity in children, disruption of the endocrine system, negative effects on reproduction and development in animals, and so on. Aside from that, the animals may exhibit symptoms of liver and kidney failure due to its toxicity.
Hence, the food color mixes more easily with the warm water than with the cold water, as the warm water has less density than the cold water, which allows the diffusion of the color in the water.

b. Name one advantage and one disadvantage of replacing wild forestland with
cropland.
Answer:
Advantage: Having the space and land to make an economy and to grow crops
Disadvantage: Destroying animal, and wildlife habitat and reducing O2 productions from trees
Explanation:
Why?
Deforestation can eliminate many living organisms and take down trees, which produce oxygen. On the plus side, the land allows for humanity to settle in, farm and start an economy.
One advantage is having the space and land to make an economy and to grow crops. One disadvantage: Destroying animal, and wildlife habitats and reducing O2 production from trees.
What is deforestation?
Many living things can be wiped out by deforestation, which also removes trees that produce oxygen. On the bright side, the land enables human settlement, agriculture, and the emergence of an economy.
The consequences of deforestation are increases in greenhouse gas emissions, which contribute to climate change, desertification, soil erosion, fewer crops, flooding, and a myriad of issues for indigenous people.
Therefore, having the room and acreage to build a business and raise crops is one benefit. One drawback is the destruction of wildlife and animal habitats, which lowers tree O2 output.

A small family farm has 230 acres of farmland to grow corn . If each acre yields 63 bushels of corn and each bushel can be sold at $9.00, how much does the farm make corn per year?
Answer:
$130,410
Explanation:
According to this question, a small family farm has 230 acres of farmland to grow corn. Each acre yields 63 bushels of corn i.e 1 acre = 63 bushels of corn
Also, each bushel can be sold at $9.00 i.e. 1 bushel = $9.00
If 1 bushel = $9.00
63 bushels = 63 × 9 = $567
Since 63 bushels of corn = 1 acre, it means that $567 is made on one acre.
Hence, on 230 acres, 230 × 567 = $130,410 will be made on corn per year

The following section explains the description and as per the given situation.
Explanation:
Throughout the 1920s, Walter Garang proposed whether vertebrates formed from some kind of pedomorphosis simplified such as lava. Garstang mentioned whether attaining sexually mature would just have frozen several tunicates throughout their larval stages at a much more early development stage, in which they'll replicate.04.

A roller coaster containing four cars is accelerating at -15 m/s2 before it comes to an abrupt stop at the end of the ride. The mass of one car is 200 kg. How much force was exerted on the roller coaster to bring it to a stop
Answer:
F = -3000 N
Explanation:
Given that,
Mass of the car, m = 200 kg
A roller coaster containing four cars is accelerating at -15 m/s²
We need to find the force exerted on the roller coaster to bring it to a stop. Let F is the force.
F = ma
Putting all the values,
F = 200 kg × (-15 m/s²)
= -3000 N
So, the force us 3000 N and it act in opposite direction.

This describes the dynamic changes between sedimentary metamorphic and igneous substances
Answer:
This is a solid substance that is composed of minerals. This describes the dynamic changes between sedimentary, metamorphic, and igneous substances. This occurs are mid-ocean ridges where a new oceanic crust is formed and then slowly moves away from the ridge.
Explanation:
The "dynamic changes" between sedimentary, metamorphic, and igneous substances refer to the processes by which these rock types are transformed from one another over time and explain the geological process.
What is the significance of the different rocks?There are different types of rocks, such as metamorphic rocks, which form from the alteration of pre-existing rocks, such as metamorphic rocks, through heat, pressure, etc., and igneous rocks, which form from the solidification of magma or lava. Sedimentary rocks form from the accumulation of sediments, such as sand and gravel, and all these rock types explain the complex geological processes.
Hence, the "dynamic changes" between sedimentary, metamorphic, and igneous substances refer to the processes by which these rock types are transformed from one another over time and explain the geological process.

Consider the contents of your stomach 1 hour after eating this meal. What, if anything, ha been digested? What, if anything, has been absorbed? Constituents What happens to_____ in the stomach? Digested or of food Absorbed? CarbohydratesFatsProteinsVitamins SucroseWater
Answer:
Proteins
Explanation:
Of all the food types, Protein has the shortest digestion process. The digestion and absorption of protein starts in the stomach where protein is converted to amino acids and other polypeptides by the enzyme pepsin and more amino acids are produced in the pancreas by the trypsin. Note that much of these amino acids are not absorbed by the body, they are excreted through the urine as uric acid.
In which of Studies 1 and 2 did some of the fruit flies live for more than 75
days, and what diet were those fruit flies fed?
Study 1; 05% SY medium
O Study 1; 15% SY medium
Study 2:05% SY medium
O Study 2; 15% SY medium
Answer: Study 2: 05% SY medium
Explanation:
The x axis on each graph shows the number of days that has elapsed while the y axis shows the percentage of fruit flies that are still alive. In the Study 1, we notice that all the fruit flies had died off by the 55th day.
In Study 2, we then see that some fruit flies lived past 75 days. Those were fruit flies which had been put in the tube that had only 5% SY medium which contains 5% sugar and 5% killed yeast.
