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.
1- Synthesize this hormone
3- a decrease in the amount of glucose in the blood
4- may have fewer side effects then the insulin previously extracted from the pancreas of other animals
5- release of insulin
6- different parts of an individual's DNA are used to direct the synthesis of different proteins...
The answer is C) 9:3:3:1
This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth
Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24
We have
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
