Answer: Gram staining is arranged in the following order;
1) Crystal violet
2) iodine
3) Alcohol-acetone
4) safranin
Explanation:
Applying primary stain to a heat fixed smear of a bacterial culture
Then you add iodine which binds the crystal violet and traps it in the cell. After you decolourise with ethanol finally counter shade with safranin
Your answers would be:
1. ---- B. A cell cannot be subdivided into smaller units that maintain the living state.
2. ---- The organism is a eukaryote because it has a nucleus.
3. ---- D. Water would flow into them because they are hypertonic to external environment.
If you want to know why:
1. The cell is the basic unit of life or in other words, its the smallest unit that makes up a living thing. It does not subdivided further if you are talking about sustaining life. Yes, it is made up of smaller units of organelles, but these organelles work together as a single unit (as a cell), to do life sustaining processes.
2. The organism is a eukaryote because of the presence of a nucleus. This is one of the main features of a eukaryote that differentiates it from a prokaryote. Prokaryotes to not have a true nucleus.
3. Water would flow into them, causing the cell to swell and eventually burst if the concentration of solutes would not even out before then. The process of osmosis is what brings the water into the cell. The cell would have a higher solute concentration than freshwater. Through osmosis, the water would then go to the area of higher concentration, which would be the cell.
The correct answer is: By using dichotomous.
I hope my answer benefites you! c:
Answer;
mRNA is synthesized from a strand of DNA
During transcription mRNA is synthesized from a strand of DNA.
Explanation;
Transcription is the process that takes place in the nucleus of a cell, where DNA molecules acts as a primer to synthesis messenger RNA, catalyzed by the enzyme RNA polymerase.
It is the first step of expression of gene, a particular segment of DNA is copied to mRNA by RNA polymerase.
Then the mRNA is transported to the cytoplasm for the process of translation in which proteins are formed.
<span>Scientific research has an integral relationship to environmental resources. Resources that exist in the environment can help scientific research by making available the material that is necessary to conduct experiments. Water is an environmental resource and scientists can test the water in the environment in order to see if there are toxic levels of chemicals in the water. Without these resources, the science would not be as relevant.</span>
