Identify each type of disturbance
Answers
Answer:
Explanation:
Acid-base disturbances have profound effects on the body. Acidemia results in arrhythmia, decreased cardiac output, depression, and bone demineralization. Alkalemia results in tetany and convulsions, weakness, polydipsia and polyuria. Thus, the body will immediately respond to changes in pH or H+, which must be kept within strict defined limits. As soon as there is a metabolic or respiratory acid-base disturbance, body buffers immediately soak up the proton (in acidosis) or release protons (alkalosis) to offset the changes in H+ (i.e. the body compensates for the changes in H+). This is very effective so minimal changes in pH occur if the body is keeping up or the acid-base abnormality is mild. However, once buffers are overwhelmed, the pH will change and kick in stronger compensatory responses. Remember that the goal of the body is to keep hydrogen (which dictates pH) within strict defined limits.

How does the ocean affect the rate of accumulation of [tex]CO_{2}[/tex] in the atmosphere?
increases it
decreases it
maintains it at a constant rate
Answers
Answer:
The ocean is a large CO2 sink because of its large surface area. The CO2 emissions are caused by human and manufacturing activities which some of them are absorbed in the ocean because CO2 is partly soluble in water. Thus, the answer is CO2 is decreased in the process.
CO2 is part of the carbon cycle and as such, moves from the land to the atmosphereby human burning of fossil fuels and forest fires,. But CO2 also moves from the atmosphere into the oceans when when the solubility is right - this is called an ongoing "flux" or movement of CO2 in and out of the oceans. Hence the oceans act as a kind of buffer to ensure that not too much CO2 remains in the atmosphere and hence the greenhouse effect will not get too strong.When the oceans are colder, they can absorb more CO2 out of the atmosphere, and when they warm up, they tend to release it back into the atmosphere. However, global warming is also now transferring heat from the atmosphere to the oceans and so the oceans are less inclined to absorb excess CO2 from the atmosphere. Also, as the oceans absorb excess CO2 from the atmosphere, this tend to make the salinity of the oceans become more acidic.

Answer:
A. grasses begin to grow in soil with organic matter
B. tress begin to grow in thick rich soil
C. mosses begin to grow in thin rocky soil
D. lichens begin to cover bare rock
It would be B. because that comes last.
Explanation:
Whenever a volcano erupts, it puts a layer of rock over everything. Basically, over years and years, lichens will start growing and breaking down the rock. A bunch of years later, mosses will begin to grow in the "soil" that the lichens broke down. When the rocky dirt becomes actual dirt, grasses will start to grow. After that shrubs, and then trees.

A science class is learning about exothermic reactions, which are reactions that transform chemical energy into heat. The students combine substance X and substance Y in a beaker. A chemical reaction between X and Y creates new substance Z. How could the students tell whether the reaction is exothermic?
A. They could measure the change in mass of substance X and substance Y using a balance.
B. They could measure the increase in temperature of the mixed substances using a thermometer.
C. They could measure how long the chemical reaction lasts using a stopwatch.
D. They could measure the volume of substance Z using a graduated cylinder.
Answers
Answer:
c
Explanation:
The students could tell whether the reaction is exothermic by measure the increase in temperature of the mixed substances using a thermometer.
What is exothermic reactions?Those reactions which produces heat in the form of energy is known as exothermic reaction.
So to tell whether the reaction is exothermic in nature student should measure the temperature of the reaction beaker befor adding the reactants and after the mixing of reactants.
They could measure the change in mass of substance X and substance Y using a balance, how long the chemical reaction lasts using a stopwatch and volume of substance Z using a graduated cylinder are not considered as they have relation with heat.Hence student could measure the increase in temperature of the mixed substances using a thermometer.

Which answer best describes the continental shelf?
75-mile shallow flat area just off coastlines
thick deposits of sediments carried out from land
the surf area along coastlines
area of land that drops toward deep ocean basins
Answers
The answer that best describes the continental shelf is thick deposits of sediments carried out from land. The correct option is b.
What is a continental shelf?Geologists refer to the portion of the continental margin between the shoreline and the shelf break—or. In the absence of a discernible slope, between the shoreline and the point where the depth of the adjacent water is roughly between 100 and 200 meters—as the "continental shelf."
Where the continental shelf stops, the continental slope starts. It serves as a dividing line between the oceanic and continental crusts, much as its name suggests.
The continental slope separates the crusts of the continents and the oceans. Gravity's effect causes soil, boulders, and debris to eventually wash down the steep sides of a continental slope over time. At the bottom of the slope, they amass into a clump.
Therefore, the correct option is b, thick deposits of sediments carried out from land.

Answer:
circulatory and excretory
plz brainliest
Explanation:
Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin. Your nervous system controls all these activities with electrical impulses.
The organ systems which are working together to helps to remove waste products from blood are circulatory system and excretory system.
What are organ systems?Organs systems are groups of organs joined together to perform specific functions in body. There are various organs systems in our body such as respiratory system, circulatory system, digestive system, excretory systems etc.
Among which, circulatory system is circulating the pure blood and oxygen through out our body. It removes wastes from blood and purify blood and oxygenate it.
Excretory system is removing liquid and solid wastes from out body with help of a pair of kidneys. They contains a large number of sieve like structure called nephrons which filter out the urine.

the half-life of sodium-24 is 15 days. A laboratory technician measures out a 72 g sample. Approximately how many grams of sodium-24 would remain after 45 days?
Answers
Answer: 9 grams left After 45 days
Explanation:
Given,
Half life of sodium-24 = 15 days
Measured Sample = 72 grams
After 45 days how many grams remains is :
Number of half lives = time elapsed / half life
Number of half lives = 45 days / 15 days
Number of half lives = 3
At time zero total amount = 72 g
After first half life = 72 g/ 2= 36 g
At 2nd half life = 36 g/2 = 18 g
At 3rd half life = 18 g/2 = 9 g
Hence After 45 days 9 grams left.

Amani wants to know if crushed ice or whole ice melts faster. She puts the whole ice in a bowl on the kitchen counter. She puts the crushed ice in a bowl in the oven. Lastly, she times both bowls of ice to see which melts fastest. Is this a valid experiment? Why or why not?
Answers
Yes,
Because she wants to know which melts faster so she puts a bowl of crushed ice in a oven, which in then can melt it. If she turns on the oven light she will be able to understand if it melts.
If she leaves it out on the counter the regular un-crushed ice, she can see if that is also melted faster but this is in fact a valid experiment.
