In 1985 a biologist counted 750 pine trees in a 250 hectare forest. Using similar counting techniques, the biologist counted 1,2

Alisiya [41]

Answer:

Suppose that we have a given function f(x)

The average rate of change of the function between two values x₁ and x₂ is given by:

$r = \frac{f(x_2) - f(x_1)}{x_2 - x_1}$

a) We want to find the average (rate) of change on the size of population from 1985 to 1995.

We have that:

f(1985) = 750

f(1995) = 1500

Then we have:

$r = \frac{1500 - 750}{1995 - 1985} = 750/10 = 75$

This means that the population of trees increases, in average, at a rate of 75 trees per year.

b) What is the density of trees each year that they were counted?

This will be equal to the quotient between the number of trees and the area.

1985: number of trees = 750 pines

area = 250 ha

Then the density is:

D(1985) = (750 pines)/(250 ha) = 3 pines/ha

So 1985, there were 3 pines per hectare.

1990: number of trees = 1250 pines

area = 250 ha

Then the density is:

D(1990) = (1250 pines)/(250 ha) = 5 pines/ha

1995: number of trees = 1500 pines

area = 250 ha

The density is:

D(1995) = (1500 pines)/(250 ha) = 6 pines/ha

3) now we want to get the average change between 1985 and 1995 in the density, this will be:

$r = \frac{D(1995) - D(1885)}{1995 - 1985} = \frac{6 pines/ha - 3pines/ha}{10} = 0.3 pines/ha$

So, on average, each year the number of pines per hectare increases by 0.3

During gene expression, the dna-to-rna step is known as , while the rna-to-protein step is known as _____.

zlopas [31]

During the process of gene expression, the DNA to RNA step is known as transcription while the RNA to protein step is known as translation.

Gene expression is a process which involves the synthesis of a functional gene product by using the information present in the genes.

Transcription is a process which involves the synthesis of a RNA from the DNA. In eukaryotic cells, the transcription occurs in the nucleus whereas in prokaryotes the transcription occurs in the cytoplasm of the cell.

Translation is the process by which the RNA is converted into a protein. The translation in prokaryotic cells occurs in the cytosol of the cell whereas in eukaryotic cells, the translation occurs in the ribosomes.

The _____ system eliminates the majority of nitrogen-containing metabolic waste products

serious [3.7K]

The urinary system, also known as renal system, eliminates the majority of nitrogen-containing metabolic waste products. It is a group of organs which filters out excess fluid and other substances from the bloodstream. The organs that compose the urinary system are: kidneys, ureters, bladder, and the urethra. The result is stable balance of salts and other substances in the blood.
