Jenny had 50 g of canola oil and 63 g of olive oil stored at room temp (20*c). She wondered Does the type of cooking oil affect how much thermal energy it takes to raise the temp of the oil? She created the follow hypothesis : If both canola oil and olivia oil are at the same temp (20* C) Then they would need the same amount of thermal energy to raise the temp to the same final temp (60* C)

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.

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.

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.

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.

All electromagnetic waves travel at the same speed in a vacuum, usually referred to as the speed of light. This speed is approximately 300,000 kilometers per second and is represented by the symbol c.
Identify the formula you can use to calculate the speed of an electromagnetic wave.
Answers
Answer:
The following formula is used to calculate the speed or velocity of a wave. V = f * w Where V is the velocity (m/s) f is the frequency (hz)
All electromagnetic waves travel at the speed of light, which is approximately 300 million metres per second (3.0 x 10⁸ m/s). The wavelength and frequency of electromagnetic waves vary. Electromagnetic waves with longer wavelengths have lower frequencies, while those with shorter wavelengths have higher frequencies.
What are electromagnetic waves ?Electromagnetic radiation is made up of electromagnetic field waves that travel through space carrying momentum and electromagnetic radiant energy. Radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays are all examples of electromagnetic waves.
In general, light travels in waves, and all electromagnetic radiation travels at the same speed through a vacuum, which is approximately 3.0 * 108 metres per second. This is referred to as the "speed of light" because nothing can move faster than the speed of light.
v = λ f.
Thus,The speed of electromagnetic waves in free space is the speed of light c = 3 × 10⁸ m/s. Electromagnetic waves have any wavelength λ or frequency f as long as λf = c.

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.

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.
