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:
Photosynthesis is a process by which plants use the sunlight to make their own food. The main role of photosynthesis is to produce food for the plant.
"<span>Based on variability, the costs has been classified into three categories, they are fixed, variable and semi variable. </span>Fixed costs<span>, as its name suggests, is fixed in total i.e. irrespective of the number of output produced. </span>Variable costs<span> vary with the number of output produced. </span>Semi-variable<span> is the type of costs, which have the characteristics of both fixed costs and variable costs".</span><span>

The DNA technology that is helping in this process is the CRISPR-Cas system.
<h3>What is the CRISPR-Cas system?</h3>
The CRISPR-Cas system is a genome editing tool that has revolutionized genetic and molecular biology.
This genome editing tool can be used to insert specific sequences of DNA into a chromosome and thus generate a new cell expressing of these genes.
In conclusion, The DNA technology referred here is CRISPR-Cas system.
