D? maybe i’m trying to. see if it’s d or b
Answer:
496.7 K
Explanation:
The efficiency of a Carnot engine is given by the equation:

where:
is the temperature of the hot reservoir
is the temperature of the cold reservoir
For the engine in the problem, we know that
is the efficiency
is the temperature of the cold reservoir
Solving for
, we find:

The volume of a cylinder is given by the formula v=pi r^2h, where r is the radius of the cylinder and h is the height.
<h3>What Does a Cylinder's Surface Area Look Like?</h3>
The overall area or region that the surface of a cylinder covers is referred to as its surface area. A cylinder's total surface area includes both the area of the curved surface and the area of the two flat surfaces because there are two flat surfaces and one curved surface. A cylinder's surface area is measured in square units like m2, in2, cm2, yd2, etc.
<h3>What is the cylinder's total surface area?</h3>
The sum of the curved surface areas makes up the cylinder's overall surface area.

Answer:
Production of GMOs is a multistage process which can be summarized as follows:
1. identification of the gene interest;
2. isolation of the gene of interest;
3. amplifying the gene to produce many copies;
4. associating the gene with an appropriate promoter and poly A sequence and insertion into plasmids;
5. multiplying the plasmid in bacteria and recovering the cloned construct for injection;
6. transference of the construct into the recipient tissue, usually fertilized eggs;
7. integration of gene into recipient genome;
8. expression of gene in recipient genome; and
9. inheritance of gene through further generations.
The basic principles that apply to circuits is that electrons must receive energy from a source, and electrons transfer energy to perform some useful function.
<h3 /><h3>What is circuit?</h3>
Individual electronic components, like resistors, transistors, are connected by metallic wires or traces by which the electric current can flow to form a circuit design.
The basic principles that apply to circuits will be;
1. Electrons must receive energy from a source.
2. Electrons transfer energy to perform some useful function.
Hence, option 1 and 2 are correct.
