Answer:

The reasons are the following.

Explanation:

Bear can live on land in a very cold regions of earth with the help of its thick skin and more hair on its body.

Frogs lives on lands due to its body structure and food availability. It has sticky tongue that captures insects.

Humans lives on lands not in water due to its body structure because its body structure can't allow humans to live in water due to absence of gills.

Seagull lives in the aquatic ecosystem because seagull feeds on fishes and other marine animals.

Sharks lives in water due to its body structure such as gills that are used to respire in water and the shark can't respire without water.

Meerkat lives in the arid climate because they lives underground to save themselves from the environment and the presence of food.

Protea lives in desert due to their dry skin that can tolerate the warm temperature.

Lions lives in the jungle due to the presence of food such as deer, buffalo etc and warm environment.

Dragonfly lives on land and water due to feed on the larva of mosquitoes that is present in the water bodies and good environmental conditions.

ELEN [110]

Answer:

Total 495 liters of natural oil are needed.

Explanation:

It is given that Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 3 liters of synthetic oil.

It means the ratio of natural oil and synthetic oil is

$\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{5}{5+3}=\frac{5}{8}$

Let in order to make 792 liters of Petrolyn oil he needs x liters of natural oil.

It means the ratio of natural oil and synthetic oil is

$\frac{\text{Natural oil}}{\text{Petrolyn motor oil}}=\frac{x}{792}$

Equate both ratios,

$\frac{x}{792}=\frac{5}{8}$

On cross multiplication we get

$8\times x=5\times 792$

$8x=3960$

Divide both sides by 8.

$x=\frac{3960}{8}$

$x=495$

Therefore total 495 liters of natural oil are needed.

<u>Answer:</u>

Heat moves from the land to the air through the process of "conduction".

<u>Explanation:</u>

When the two things come in contact with one another at different temperatures or basically when heat flows from the warmer to the colder region or phase until both reach at the same temperature is understood as "conduction". Conduction is a physical process which occur by collision of the microscopically colliding particles like molecules, atoms and electrons on the movement of heat through a substance.

While convection take place by the movement of heated objects and it isn't the process influencing air and water temperature difference. The examples of conduction are like a radiator, a heating pad, sand can conduct heat etc.

The frontal lobe of the brain is _____ for driving a motor vehicle.

ANTONII [103]

The frontal lobe of the brain is not essential for driving a motor vehicle. The only time that the frontal lobe would be activated during driving would be when there is potential danger, for example a car swerving in front of you. The dorsal lateral prefrontal cortex is more essential for driving, as it is involved in judgment and decision making.
