Answer:
Cell wall
Explanation:
Plant cells have cell wall, chloroplast, and central vacuole.. which cannot be found in animal cell
Answer:
Controlling the proteins in an organism controls the organism's characteristics because proteins are enzymes, and enzymes catalyze and regulate chemical reactions, and therefore can control certain traits such as color, shape, or even gender.
Explanation:
DNA unwinding begins at the Origin of replication.
Answer:
The statement supported by the description of the process of protein synthesis determined by DNA and its packaging and sorted by the Golgi apparatus is that various organelles within a cell interact with each other to carry out life processes (option D).
Explanation:
From the transcription of RNA from DNA to protein synthesis and its packaging and distribution, the participation of organelles is observed:
- <em>Cell nucleus</em><em>: contains the DNA and is where the transcription into mRNA occurs.
</em>
- <em>Ribosomes</em><em>: where the mRNA is coupled to produce translation and protein synthesis.
</em>
- <em>Rough endoplasmic reticulum</em><em>: contains ribosomes and participates in the process of membrane protein synthesis, also contributing to their conjugation, glycosylation or sulfonation.
</em>
- <em>Golgi apparatus</em><em>: it is in charge of receiving synthesized proteins, packaging and distributing them to be sent to the extracellular space or other cells.
</em>
In this way, the coordination of the functions of various organelles is useful and necessary to fulfill vital functions. The statement that varoius organelles within the cell interact with each other to carry out life processes is, therefore, correct.
<em>The options for this question are:</em>
<em> A. Organelles within a cell act independently of each other at all times
</em>
<em> B. Some organelles are more important than other organelles within a cell.
</em>
<em> C. Only up to three organelles may interact with each other at any given moment in time.
</em>
<em> D. </em><u><em>Various organelles within a cell interact with each other to carry out life processes.</em></u>
Answer:
Neither observer nor subjects know which subject receives the vaccine and which receives a placebo
Explanation:
In a double-blind study neither the participants nor the experimenters is aware of who is receiving a particular treatment.
Its used to prevent bias in research results from demand characteristics or the placebo effect
