Answer:
The right answer is intercalated discs.
Explanation:
If you observe cardiac muscles under a microscope, the first feature that appears is Intercalated discs. Cardiac muscles contains heart muscle cells which are called as cardiomyocytes which are linked by these discs to perform a single functional organ.
Intercalated discs helps in harmonizing the contraction of cardiac tissues.
The sentence which should come next in the paragraph to maintain the compare contrast structure is, Gerbils have long furry tails, while hamsters do not have tails.
Answer: Option C
<u>Explanation:</u>
Compare and contrast text structure is basically a type of structure where two things are compared and contrasted at the same time. In simple terms, comparison is finding the similarities whereas contrast means finding the differences.
When it comes to Gerbils and hamsters, both these organism have many similarities. The only difference is in their tail. Gerbils have a very long and furry tail, hamsters on the other hand have a very short tail. Their tails are so short that one often find it difficult to notice its tail.

Explanation:
Rr*Rr punnet square
Results
RR round
Rr round

50% round heterozygous
25% oval homozygous
Answer:
<h2>Incomplete dominance</h2>
Explanation:
As given here;
Two pure line of four-o'clock plant, one having red flower and other having white flower, when they are crossed, they produce all pink progeny.
So, lets red as RR and white as rr
Cross between RR and rr
Here all offspring are Rr ( Pink ).
It's the result of incomplete dominance, in complete dominance the offspring is the intermediate of both the parents.
F2 generation:
As cross between Rr and Rr
progeny are: RR, Rr, Rr, rr
RR =red
Rr= pink
rr= white
So, red: pink: white = 25:50:25
Since, the experiment is not given but on the basis of the mechanism of genetic transfer this question can be answered.
Answer:
The mechanism of gene transfer is important and beneficial for bacteria in the adverse environment conditions. The different mechanism of gene transfer are conjugation, transformation and transduction.
The ampicillin resistance gene is present on the plasmid DNA and not on the chromosomal DNA. Only conjugation is the mechanism in which the plasmid DNA is transferred from one bacteria to another bacteria. The ampicillin resistance gene is transferred from Strain II to strain I means from the bacteria that has the ampicillin resistance gene to the bacteria that has no ampicillin resistance gene in it.
