Answer:
The correct answer is
d. heating evaporative cooling and mineral transport
Explanation:
Plants transpire to expel excess heat energy by a process known as evaporative cooling. As the water involved in transpiration evaporates, heat energy is transferred from the plant system into the surrounding environment cooling down the plant.
During transpiration, the stomata of the plant are open allowing the outward flow of the evaporated water and also the open stomata enable the plant to absorb carbon dioxide (CO2) from the atmosphere. The carbon dioxide is required in photosynthesis for the formation glucose while producing oxygen as well.
The water also transports nutrients dissolved in it as it is being transported to the leafs for evaporation. These nutrients are thus delivered tm all parts of the plant.
I believe the givens should be written in this manner,
(4.2 x 10⁵)(4.0 x 10⁻⁹)
To answer, we first multiply the bases 4.2 and 4 which will give us,
16.8
Then, we multiply the multipliers by adding up the exponents of 10. This will give us the answer of,
16.8 x 10⁻⁴
Then, the final answer would be 1.68 x 10⁻³.
Answer:
B, produces animals that can yield greater amounts of milk, meat, or eggs
Explanation:
it is the only answer that is a positive outcome of selective breeding
Answer:
Saturated, water-bearing materials often exist in horizontal layers beneath the land surface. Since rivers, in time, may cut vertically into the ground as they flow, the water-bearing layers of rock can become exposed on the river banks. Thus, some of the water in rivers is attributed to flow coming out of the banks.

Answer: radio and television
Satellite orbits with an East-West orientation are best used
for communication purposes. The satellite orbit should always be suited for its
purpose. Radio and television are powered by numerous satellites rotating the
Earth from east to west.
