A gene directs the synthesis of a protein<span> by a two-step process. First, the instructions in the </span>gene<span> in the DNA are copied into a messenger RNA (mRNA) molecule. The sequence of nucleotides in the </span>gene<span> determines the sequence of nucleotides in the mRNA. This step is called transcription.</span>
Answer:
1,250,000 shrimps per m³
Explanation:
Population density refers to how dense an area is per unit area/volume, and it is calculated by dividing the number of individuals in that area (population) by the area/volume of that area. That is;
Population density = population (N)/volume
According to this question, a certain lake has a volume of about 480 m³ that harbors a 600 million of freshwater shrimp. This means that;
Population density of the lake = population of shrimps ÷ volume of lake
Population density = 600,000,000 ÷ 480
Population density = 1,250,000 shrimps per m³
The class iv calcium blocker that exclusively administered to treat acute supraventricular tachyxardia is Diltiazem. Calcium channel blockers obstruct the movement of calcium into conductive and contractile myocardial cells by inhibiting the influx of calcium through its channels, causing a slower conduction through the SA and AV. Diltiazem is administered intravenously to treat acute supraventricular tachycardia.
Answer:
BENEFITS:
The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.
A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.
The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.
LIMITATIONS:
<u>descriptive method of investigation
</u>
It cannot be used to correct variable or be used to determine causes and effect of the problem
<u>experimental method of investigation
</u>
It might create an artificial situation that do not always represent the real life situation
<u>comparative method of investigation
</u>
It is not easy to control other variables that might influence the study
