From the information provided here, it can be said that both the types of organisms contain exactly the same four nitrogen bases, but in different sequences and numbers. Thu, the correct option is C.
The genetic code is a set of rules which defines how the four-letter code of the DNA is translated into the 20-letter code of amino acids in an organism, which are the building blocks of proteins in that organism.
The genetic code is almost completely universal across all the different life forms, with a few minor differences in some of the bacteria such as Mycoplasma and in the bacterial-derived lineages such as mammalian mitochondria and chloroplast of plant cells. The variation is due to the codon usage.
The genetic code consists of the sequence of bases in the DNA or RNA molecules. Groups of three bases form codons, and each codon in this stands for one amino acid. The codons are read in the sequence following the start codon until a stop codon is reached in that sequence. The genetic code is universal, unambiguous, and redundant.
Therefore, the correct option is C.

B. churning movements of the gastrointestinal tract
C. pendular movements of the gastrointestinal tract
D. waves of muscular contractions that propel contents from one point to another
Answer:
Option (D).
Explanation:
Peristaltic movements are involuntary movement occur due to the longitudinal and circular muscle.Peristaltic waves helps in the passage of food from one point to another during the process of digestion.
Peristaltic waves occur mainly due to muscular contraction. These contractions propel the contents from one location to another. These waves occur in stomach, intestine and esophagus.
Thus, the correct answer is option (D).
Peristaltic waves are waves of muscular contractions that propel contents from one point to another. Therefore, the option is D.
The waves of muscular contractions known as peristaltic waves are responsible for moving materials from one location to another. They are in charge of the transportation of food through the digestive system from beginning to end.
Therefore, peristaltic waves are waves of muscular contractions that propel contents from one point to another

How many times does the rrTt combination appear in this Punnett square?
Answer: The combination produced is RRtt.
The combination rrTt does not appear in this punnett square.
Explanation:
As the problem does not indicate more information, I assume that punnett square is made between two RRtt genotypes. It can produce gametes that have the alleles Rt. A gamete is a sexual cell (egg or sperm) that has only one allele of each gene. And, each gamete codes for a different gene. Since here we have two different types of alleles (R and t), it is a dihybrid cross.
A Punnett square is a diagram used to predict the genotypes of a cross or breeding experiment. It is used to determine the genotypes and phenotypes of the offspring. To do it, you have to label the rows with one parent's gametes and label the columns with the other parent's genotype. Then, have each box inherit letters from its row and column, and interpret the results.
Then, the punnett square (shown in the picture) will be between RRtt and RRtt whose gametes can only be Rt, so Rt x Rt will be made.
The result in an offspring which will be 100% RRtt, and there is no rrTt combination here because non of the parents have an r allele, then none of the children can inherit it.
To have an offspring where rrTt genotype is shown, a different genotype must be used, in which both parents must have at least one r allele and one t allele. For example, it could be Rrtt x rrTt.
