Polygenic inheritance is the pattern of inheritance where a wide range of phenotypes that result from many gene pairs in an individual organisms controlling a single trait.
Examples would include = skin colour and or measurement of height.
Answer:D.D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.
Explanation
Options A-C are correct except D.
→Increase in Telomere length is indicative of abnormal growth, cancer cells can reactive telomerase to increase cell's length.
→Once a monolayer is reached; this a stage of a complete normal cell division , a cell that goes beyond this stage must be mutated. assuming all other factors are constant .
Uncontrolled cell division is an indication of virulent growth in mutated cells.
<u>Cancer cell requires a ,medium of living host to thrive, alga medium will not support growth for carcinoma cells -the correct answer. </u>

:Imagine that you are a graduate student working in a cancer lab. You accidentally mix unlabeled tubes of carcinoma cells with tubes of normal epithelial cells. Which of the following is NOT a possible strategy to allow you to distinguish which tubes contain carcinoma cells?
A.)Monitor telomere length over time during multiple cell divisions.
B.) Plate the cells in culture and look for the culture that stops dividing once a monolayer is reached.
C.) Monitor the rate of cell division.
D.) Suspend the cells in liquid agar culture and monitor which culture continues to grow.
Answer: Coelenterates as a whole are of little economic importance. Seldom used as food by man, they are eagerly devoured by certain fishes and by invertebrates such as the crown of thorns starfish. Certain corals used as ornaments and for the manufacture of jewelry have become rare because of exploitation.

Answer:
If a DNA strand has the base sequence TTCCGGAA the complementary strand has the sequence AAGGCCTT.
Explanation:
A DNA molecule is constructed from sequences of its four nitrogenous bases: adenine, thymine, guanine and cytosine. Since DNA is made up of two strands, the sequence of nitrogenous bases of one strand is complementary to the other
.
The complementarity of the bases is a characteristic of the nitrogenous bases in the nucleic acids to combine with their complementary base, which is the same as saying that purines complement with pyramidines.
- <em>Adenine is combined with Thymine A=T
</em>
- <em>Cytosine is complemented with Guanina C≡G
</em>
In this way, given a sequence on a DNA strand
:
<em> T-T-C-C-G-G-A-A</em>
The complementary strand will have this sequence:
<em> A-A-G-G-C-C-T-T</em>
The frequency will be one in a ten thousand, in a real life situation. The X-linked recessive disorder has the same frequency as that of its frequency in the men. The frequency in women is close to zero, and in 5000 men, it will be one, so in total, the allele frequency will be 1/10000.
When we use a Punnett sqare, it comes out that 0% of the females will have he disease. But, as 50% of the eggs of the mother will carry a recessive allele, 50% of the male offprings bear the cahnces of being affected, i.e., 25% of the total offsprings, which mean 2500 male children bear the chance of having Hemophilia.
