To solve this problem on genetic dominance, we will need a punnet square.
Let's let P represent purple-flowered and p represent white-flowered.
We have one purple flowered plant with the alleles PP, and we have one white flowered plant with the alleles pp. Using a punnet square, we can determine the alleles of the offspring.
<u>P</u> <u>P</u>
p| Pp Pp
p | Pp Pp
As we can tell from our punnet square, all of our offspring will have purple flowers. This is because the purple-flower allele is dominant and the white-flowered allele is recessive.
Since each flower has a dominant and recessive allele, they are heterozygous.
Therefore, the solution to this problem is D.
To locate <u>positions</u> in east and west directions, <u>cartographers</u> use lines of <u>longitude</u>, also known as <u>meridians</u>. Longitude is the distance in degrees <u>east</u> or <u>west</u> of the prime meridian, which is the reference point for longitude.
<h3>What is a topographic map?</h3>
A topographic map can be defined as a type of map which contains an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of planet Earth.
Generally, a topographic map make use of contour lines to represent points of equal elevation above sea level such as:
- Mountains
- Hills
- Plains
- Valley
<h3>What is a line of longitude?</h3>
A line of longitude can be defined as an imaginary great circle of constant longitude on the surface of planet Earth which passes through the North pole (terrestrial pole) and South poles (Meridian) at right angles to the equator.

Answer:
Explanation:
Antibodies are blood proteins produced to combine with and combat specific antigens and foreign substances such as bacteria and viruses.
An antibody which is also known as immunoglobulin is a Y-shaped structure that normally consists of 4 polypeptides which are 2 heavy chains and 2 light chains. This is the structure that makes it possible for antibodies to carry out their double functions which are - Antigen binding and Biological activity mediation.
Each role is executed by different parts of the antibody. That is, the fragment crystallizable region known as the fc region and the fragment antigen binding known as fab fragment.
The fab fragment is an area on the antibody that joins to antigens. It normally consists of one variable and one static domain of each of the light chain as well as the heavy one.
The fragment crystallizable region is the tail area of an antibody that combines with surface receptors and proteins of the complement system.This normally enables the antibodies to activate the immune system
They are found in proteins
