Answer:

Well,if this place can only support a maximum amount of 40 wolves and 55 wolves are living in the area, the wolves population will decrease.

A student made a model of a cell. First, she filled a clear plastic bag with gelatin.

Ksivusya [100]

B) the model does not show that cells can contain smaller structures inside.

This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.

Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.

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

Ugo [173]

Some bones develop within sheet like layers of connective tissue which are called intramembranous bones whereas the bones that are develop from a model of hyaline cartilage and are called endochondral bones.

<h3>Formation of intramembranous bones and endochondral bones</h3>

Endochondral ossification involves the replacement of hyaline cartilage with bony tissue which leads to the formation of endochondral bones whereas, intramembranous ossification refers to the replacement of sheet-like connective tissue membranes with bony tissue which results in the formation of intramembranous bones.
