light colored frogs becasue they can't survive in this muddy and pulloted pond
Answer:
The correct answer is multicellular organisms.
Explanation:
Organs are differentiated structure formed by group of cells and tissues to perform the similar functions. When more than two organs perform specific function in a coordinated manner they form organ system.
Tissues and organs are a characteristic feature of multicellular organisms as more than one cell is present in these organisms and these cells aggregate together to form tissues, which further aggregate to form different organs carrying out the different functions attaining complexity.
Since, unicellular organisms do not have more than one cell, unicellular cells do not form tissues and lack organs.
Thus, the correct answer is multicellular organisms.
which is absent in unicellular organisms.
Answer:
The results of the mice are different from the expected ratio because alleles assort independently in gametes at the time of gamete formation. Although, we can check the probability of the alleles the offsprings from a cross will carry, but we cannot exactly tell that which gamete will acquire which allele. Hence, the ration through a punnet square is just an assumption. The actual values might defer as alleles assort independently.
The question is incomplete as it does not have the options which are:
-It is established by the promoter.
-It is the DNA strand that runs from the 3′ → 5′ direction
-It doesn't matter which strand is the template because they are complementary and will produce the same mRNA.
-It is the DNA strand that runs from the 5′ → 3′ direction.
-It is signaled by a polyadenylation signal sequence.
Answer:
-It is established by the promoter.
Explanation:
A promoter is a sequence of nucleotides about 1000 bp in the gene which contains the specific nucleotides in the sequence.
The promoter sequence contains the sequence for binding of the RNA polymerase, specific TATA nucleotides, and TSS or transcription start site.
It is the presence of this promoter which determines which strand will be the template strand and which will be the coding strand.
Since the transcription promoter is usually present on the strand which runs from 3' to 5' as RNA polymerase bind new nucleotide at 3'end of the growing chain, therefore, the strand with promoter sequence in that direction decides the fate of the DNA strands and transcription.
