The purpose of a presumptive test is to see which substance the sample is.
Answer:
Underground stem, Aerial stem, and subaerial stem.
Explanation:
Plant stems can be Underground stem, Aerial stem, and subaerial stem due to its presence and strength of the stem. Underground stem are thick stems that run below the ground surface. e.g rhizome. Aerial stems are thin stems that can not stand erect. Examples include watermelon and strawberry etc. Subaerial stems are very thin stems that do not rise up but grow just above the ground. for example, water plantain, flowering rush etc.
I guess the stomach is held in place by a variety of Muscle cells, Epithelial cells, and connecting tissues; so the answer is: all of the above.
Answer:
Methionine- Serine- Histidine- Aspartate- Glycine- stop
Explanation:
Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.
In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the
mRNA sequence from this DNA during transcription will be:
AUG UCC CAC GAU GGG UGA
From this mRNA sequence, the peptide chain that will result following translation is:
Methionine- Serine- Histidine- Aspartate- Glycine- stop
