Endoplasmic reticulum is situated close to the nucleus and is involved
in protein synthesis. Rough ER has lysosomes around the edges.
Lysosomes - The cleaner of the cell. Small and numerous, increases
surface area and increases the rate at which waste products are removed
from the cell.
Chloroplasts - Made up of Grana, stacked up to increase surface area.
This allows more Chlorophyll to be made to increase the rate of
photosynthesis.
Nucleus - Information point of the cell</span>
Answer:
In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

For this reason:

Answer: Via ice chips or water, although not appropriate for all patients.
Explanation:
Patient is allowed to drink water btwn meals (beginning a minimum of 30 mins after meals); oral care must be done prior to consuming water; patient should be upright and use appropriate swallowing strategies.
A. The increased biomass in the sunlit dish came from the carbon and oxygen atoms present in the carbon dioxide it took up during photosynthesis that it used to synthesize organic molecules.
Plants use photosynthesis in order to convert light energy (from the sun) into chemical energy, stored in carbohydrate molecules (such as sugars). This chemical energy can be further transformed to fuel some of the organism's activities. This chemical reaction (photosynthesis) is light-dependent and includes the use of carbon dioxide and water to produce sugars and oxygen. The seeds that were put on a sunny windowsill had plenty of light energy needed for their photosynthetic activity. This resulted in the accumulation of sugar molecules in the plant tissues and an increase in the biomass. These sugar molecules were synthesized by the carbon and oxygen atoms comprising the carbon dioxide molecules absorbed during photosynthesis.
B. The most likely explanation for the why the dark-grown seedling lost biomass is that cellular respiration in the cells of the seedlings consumed the starch and oils present in the seed as sources of energy.
Plants use cellular respiration in order to constantly supply energy to their cells. This chemical reaction uses the sugar molecules produced by the photosynthesis and stored in the plant tissues to get energy. Seeds put in a dark cupboard did not have access to any light energy, therefore, they could not perform photosynthesis. As a result, they had to perform respiration and consume starch and oils which were present in the seed to get the necessary energy. This resulted in a reduction in their biomass.
