For any given gene, what ultimately determines which dna strand serves as the template strand?

vivado [14]

The answer is the base sequence of gene's promoter.

DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.

A sample is termed ____ if it has similar characteristics to the population being studied.

saveliy_v [14]

A sample is termed REPRESENTATIVE SAMPLE if it has similar characteristics to the population being studied.

The representativeness of a sample is the extent to which its characteristics accurately reflects the characteristics of the population being studied.

What are the four classes of nutrients?

Harrizon [31]

Answer:

Nutrients are grouped into macronutrients and micronutrients. Carbohydrates, proteins, fats and water are macronutrients, and vitamins and minerals are micronutrients. Although most foods are mixtures of nutrients, many of them contain a lot of one nutrient and a little of the other nutrients.There are six major nutrients: Carbohydrates (CHO), Lipids (fats), Proteins, Vitamins, Minerals, Water.

1. The effect of initial population sizes on the growth of populations of an organism was

ella [17]

When graphing data, we must consider the variables, label axes, define units of measure. In this case, variables are initial population size / final population size, showing an directly proportional relationship.

-------------------------------------

We need to construct a graph illustrating the data in the table.

We can make a dispersion graph. To do it, we need to define variables.

Since we want to know how different initial population sizes affect population growth,

the independent variable is the initial population size
the dependent variable is the final population size (after 24 hours)

The final population size depends on the initial population size. This is, the number of individuals at the beginning will influence the final number of individuals.

Initial population sizes ⇒X horizontal ax ⇒Unit: Number of individuals
Final population sizes ⇒ Y vertical ax ⇒ Unit: Number of individuals

By making a dispersion graph, we can represent the effect of the varying initial population sizes on the final population sizes. We can compare these effects and observe how populations grow as the N₀ increases.

We can also choose a bar graph. In this way, we can compare initial and final population sizes.

This graph will show populations and two bars per population.

Blue bar ⇒N₀⇒ Initial population size
Red bar ⇒N₁ ⇒ Final population size

Different populations ⇒ 1, 2, 3, 4, 5 ⇒ Represented in the X horizontal ax

The number of individuals ⇒ from 1 to 324 ⇒ Represented in the Y vertical ax.

By making a bar graph, we can represent initial and final population sizes and compare them. The population that begins with 1 individual, after 24 hours has 4 individuals. The population that begins with 3 individuals, ends with 9 individuals. And so on.

No matter which graph you choose, you will observe a directly proportional relationship between both variables. The bigger is the initial population size, the bigger it ends after 24 hs.
