Answer:
Option D is correct.
Unit rate = $75.46/ share
Explanation:
Unit rate defined as the rate are expressed as a quantity 1, such as 3 feet per second or 8 miles per hour, they are called unit rates.
Given the statement: $6,188 for 82 shares of stock.
⇒Number of share = 82
Substitute the given values we get;
Therefore, the unit rate (nearest to hundredth place) is, $75.46/ share
Answer:
10°C.
Explanation:
Heat released in any system can be calculated as follows:
Heat released = m c DT
Here, m is the mass , c is the specific heat and DT is the change in temperature.
Heat released = 200 kcalories = 200,000 calories
The mass of water = 20 kg = 20000 g
The specific heat of water = 1 cal / g degree
The rise in the temperature is as follows:
heat released = m c DT
200,000 = 20,000 ( 1) (DT)
DT = 10°C.
Thus, the answer is 10°C.
A. biodiversity increases ecosystem stability for a given type of ecosystem.
B. ecosystems are highly interconnected and the removal of even a few species can cause ecosystem disruption.
C. the diverse organisms of Earth's ecosystems provide services for humans that humans cannot replicate.
D. all of these
Answer:
Answer choice D
b. the plant flower opening with the sunrise
c. the plant root growing down into the soil
d. the plant turning towards the sun
Answer:
c. the plant root growing down into the soil
Explanation:
The plant root going down deep into the soil is an example of positive gravitropism. Gravity pulls everything towards the center of earth i.e. downwards and roots follow the direction of gravity automatically by growing downward towards soil that is why it is known as positive gravitropism. In short we can say that root favors the direction of gravity.
Shoot on the other hand show negative geotropism/gravitropism i.e. it grows towards the opposite direction of gravity. Shoot grow towards upside direction i.e. away from the surface towards sky.
