Answer:

Differences in beak shapes tell us that all the finches eat the same type of food. Different finch beak shapes are evidence that all Galápagos finches shared a common ancestor a long time ago. Different finch beak shapes are evidence that over time, finch species adapted to different food sources on the islands.

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.

A marked decrease in brain processing and memory in some older adults is MOST likely caused by: A. inadequate control processes.

Andru [333]

Answer:

Option-B

Explanation:

The brain is an organ composed of neurons which controls all the voluntary and involuntary of animals. In humans, the brain is located in the skull where the brain is suspended in a fluid called cerebrospinal fluid.

As humans ages and becomes old aged, the neurons in the brain losing their ability to perform their function, if they are lost they cannot be regenerated.

The lesions appear on the white matter of the brain and the brain shrink. Due to these known and other unknown features, the process controlled by these neurons become inadequate and shows slower brain processing and weak memory.

Thus, Option-B is the correct answer.
