Ecosystem condition can vary as a result of fire, flooding, drought, extinctions, invasive species, climate change, mining, overexploitation in fishing, farming or logging, chemical spills, and a host of other reasons.

Based on the function of dna polymerase explain why each part of the name dna polymerase makes sense?

Sauron [17]

The enzyme known as DNA polymerase is responsible for creating DNA from nucleotide monomers. The enzyme's functions are indicated by its name, DNA polymerase. The term "DNA" refers to the fact that it generates DNA utilising nucleotides. "Polymer" signifies that the enzyme is converting monomeric nucleotides into a polymer molecule. Lastly, "ase" refers to an enzyme.

<h3>What role does DNA polymerase play ?</h3>

The primary role of DNA polymerases is to preserve the genome and guarantee that the genetic code is reliably transmitted from one generation to the next.

The essential enzyme for replication in eukaryotes is DNA polymerase. Additional DNA polymerases are used for primer removal, repair, and proofreading.

Once you have stopped for a school bus, do not pass until the driver signals you to proceed, the red lights stop flashing,

DaniilM [7]

Once you have stopped for a school bus, do not pass until the driver signals you to proceed, the red lights stop flashing, or the bus starts moving ahead. Whenever a vehicle ahead of you stops to let a pedestrian pass in front of you, you should stay in line and until the vehicle ahead proceeds.

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

Which factor most likely caused animals and plants in India to differ greatly from species in nearby southeast Asia?

Dominik [7]

Answer:

India was a separate continent until 45 million years ago

Explanation:

India was part of the Gondwanaland continent which was one of the two remnants of Pangaea, while Asia was part of Laurasia, the other remnant of Pangaea. Because these two land masses were separate, the animals and plants were evolving separately for millions of years. India further separated from Gondwanaland, and it was actually a very large island for millions of years, resulting in isolation and development of unique animals and plants because of it. As India was moving it reached Asia and collided with it, thus becoming one land mass. Some Asian species managed to get in India, but mostly in its northern parts, while the central and southern parts remained dominated by the indigenous species. The Himalayan Mountain Range that formed because of the collision also helped in preserving lot of the indigenous species as it became a natural barrier that most species can not go through.
