Witch two examples show adaptations for plants growing the desert

gladu [14]

Answer and Explanation:

In some, the leaves are needle-like and stomata are reduced in number and located in cavities on the epidermis. A layer of moist air builds up in the cavity. This reduces the humidity difference between the intercellular air spaces in the leaf and the immediate external environment thus reducing the rate of transpiration.

In some the epidermis of the leaves is multilayered and is covered with a thick waxy cuticle which reduces water loss through evaporation, e.g. oleander. The cuticle is normally shiny which helps to reflect solar radiation preventing the leaf from heating up rapidly.

Sam looked at an image of an embryo that is a compact mass of cells. Which is the term for this embryo? A)gastrula B)zygote C)mo

Nezavi [6.7K]

Answer:

The correct answer is option A, Gastrula

Explanation:

Gastrula has three layers of cell and it is the phase in which single layered blastula matures and get converted into multilayered structure.

However, Morula is formed after the formation of blastula through the process of blastulation. In the Morula phase, blastomers get arranged in a spherical shape after the zygote split. And zygote is formed at a very early stage of fertilization .

Thus , gastrula is the correct answer as it is the stage which comes after zygote and morula and thus get developed into more compact mass of cells.

In the family pedigree the majority of individuals that are colorblind are which gender? This is a good indicator that colorblin

irakobra [83]

Answer:

The 'gene' which causes (inherited, red and green types of) colour blindness is found only on the X chromosome. So, for a male to be colour blind the colour blindness 'gene' only has to appear on his X chromosome. For a female to be colour blind it must be present on both of her X chromosomes.

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
