Answer: peristalsis
Explanation:it's the contraction and relaxation of muscles as the bolus moves down the oesophagus
Answer:
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
Complete question:
You will find the cladogram in the attached files
Answer:
- multicellularity
- xylem/phloem
- flowers
Explanation:
Based on this cladogram, the order of changes was multicellularity, vascular system, flowers.
<em>Multicellularity.</em> The first division or point of divergence is located between moss and the rest of the organisms. Moss is included in the Bryophyta group, characterized for being the first terrestrial plants. They are not vascular plants, and their general structure is simple but pluricellular. Multicellularity implicates association between different cells that specialized in accomplishing different functions. This complex association works to make the organism survive. Algae might be unicellular or pluricellular. Although is not the same, unicellular algae might form colonies, that are groups of cells agglomerated.
Xylem/ Phloem: The second change is related to the vascular system. Cycads are gymnosperms. These are vascular plants that produce naked seeds. The vascular system developed by gymnosperms is very elaborated, with secondary growth, and including supporting cells that allow these plants to get bigger dimensions, particularly in height.
Flowers: The last change is related to the emergence of flowers. Arabidopsis is included in the angiosperm group, the most evolved one, with great capabilities of reproduction and dispersion. They have flowers, which carry the reproductive structures. Once occurred fertilization, fruits develop and carry the seeds. Flowers might be unisexual or hermaphrodites. Their vascular system is also very complex and adapted to different environments.
The question is incomplete as it does not have the options which are:
- manufactured proteins to be short and defective
- the DNA to break up into thousands of short segments
- incorrect pairing between mRNA codons and amino acids
- no bad effects, as long as the stop codons are not also inserted into tRNA
- all of the above
Answer:
manufactured proteins to be short and defective
Explanation:
The virus particle replicates in the host machinery by using its DNA replication machinery and then transcription and translation machinery.
If by chance, the virus particle inserts stop codon along with the segments of DNA therefore the stop codon will show its effect during the translation process when the DNA sequence is translated into the proteins.
When the stop codon will be read during the translation then the protein synthesis will stop at that time and short or defective proteins will be produced.
Thus, the selected option is correct.
The pulmonary embolism is mostly likely to have originated from the Deep veins of the leg response feedback. Pulmonary embolism occurs when a clump of material, most often a blood clot, gets wedged into artery in your lungs. These blood clots most commonly come from the deep veins of your legs. It is a blockage of an artery in the lungs by a substance that has moved from else where in the body through the bloodstream.
