Drilling for fossil fuels.

This is because the main fossil fuels are not typically found in the rainforest. To also back up this claim, use the process of elimination.

The last choice, demand for rainforest products, is obviously incorrect as that would mean expansion into the rainforest to gather said products.

Shortage of food sources wouldn't be the correct answer either as food sources aren't typically found in the rainforest among popular demand and food can be shipped into the country as well. 

Overcrowding in cities would also lead to expansion, where to can differ based on location but to rainforests or anywhere surrounding the area would be preferred or desirable.

Hope this helps!

Ray Of Light [21]

Answer:

50%

Explanation:

Let the allele for red-green color blindness be represented by c.

Normal vision woman whose father is color-blind will be X^CX^c

Color-blind male will be X^cY

X^CX^c   x   X^cY

Progeny: X^CX^c, X^CY, X^cX^c, X^cY (See the attached image)

<em>Out of the 2 male progeny, 1 is affected for color-blindness while the other is not affected. This gives a 50% probability that a son of the couple will be color-blind.</em>

What is an example of reactivity?
igor_vitrenko [27]

Answer:

D. A bicycle rusting.

Explanation:

A. is incorrect because tearing a piece of paper is a physical change, not a chemical change.

B. is incorrect because we are just heating up the object. That only changes how fast the particles are moving and the change in state of matter.

C. is incorrect because we are adding heat to change a state of matter (from solid to liquid) and it is a physical change.

Therefore, only D. is the correct answer. Iron rusts, and when it does, it chemically changes into an iron oxide (rust).

gogolik [260]

Answer:

d. K+ and Na+ both diffuse into the cell along their concentration gradients and drive the transport of glucose.

Explanation:

Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence,concentration of Na is higher outside the cell, while K concentration is higher inside the cell.

Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.

This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
