Answer:
Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell (unicellular), according to the educational website CK-12.
Answer:
A. a lamp being turned on
B. a toaster being used to toast bread
D. a car horn honking
Explanation:
Energy transformation is the conversion of one form of energy to another form in accordance with the law of conservation of energy. According to this question, Phil is observing a flashlight, which turns chemical energy (batteries) into light energy.
From the examples given in this question, the following are examples of scenarios that involve energy transformation:
- A lamp being turned on: This converts chemical energy to light energy.
- A toaster being used to toast bread: This converts electrical energy to heat energy.
- A car horn honking: This converts electrical energy to sound energy.
Note that, melting of a chocolate does not transform any form of energy.
Answer: The correct answer would be 112.5 pounds
Explanation:
Let us first covert the pound into grams. We know that 1 pound is equal to 453.59 grams.
Thus, 50 pound of fat = 50 x 453.59 = 22,679.5 grams.
We know that, 1 gram of fat releases 9 Kcal of energy. Thus, total energy produced by 22679.5 grams = 9 x 22679.5 = 204,115.5 Kcal
Glycogen is carbohydrate thus, it will produce 4 Kcal of energy per gram.
Thus, 4 x C = 204,115.5 (where C is the grams of glycogen)
⇒ C = 
⇒ C = 51,028.875 grams
Using 1 pound = 453.59 grams, we con convert 51,028.875 grams into pounds:
453.59 = 1
1 = 
51,028.875 = 
= 112.5 pounds
Thus, 112.5 pound of glycogen would be needed to produce the same amount of energy as produced by 50 pounds of fat.
Estimates of current rates of extinction indicate that rates may be greater than extinction rates seen in the fossil records.
<h3>What is extinction of species?</h3>
Extinction of species refers to the event in which species of organisms are entirely wiped from existence either by man-made causes, natural disasters or disease.
The recent industrial age and many technological advancements by man has resulted in rapid extinction of species .
Estimates of current rates of extinction indicate that rates may be greater than extinction rates seen in the fossil records.
