Answer: D
They can only change one variable at a time, either water or light, not both. They could test the response to water first and follow that with an experiment for the plant's response to light. They cannot test for both at the same time.
There 2 ways to solve this
1- Directly :
80% of water in the fresh berries è 20% of water in the dried berries
36 Ibs of the fresh berries è X Ibs of the dried berries
X =
<span> = 9 Ibs</span>
<span>2- </span>If you do not understand the first method, the second one is more explicit:
First, we gonna calculate the weight of the berries without water (dehydrated):
<span>36 * 80% = 28.8 Ibs (of water in the berries)</span>
Then:
<span>36 – 28.8 = 7.2 Ibs (of completely dehydrated berries)</span>
Next, we gonna add 20% of water in the dehydrated berries:
X (total weight of dried berries) è 100%
7.2 Ibs of dehydrated berries è 80%
X = <span> </span>
= 9 Ibs
Seismology. Example:
Then there was the development of seismology, the study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies, in the early 20th century
Answer:
The nervous system and circulatory system
Explanation:
Before cell reproduction or mitosis can proceed, the correct sequence of steps that must first occur is the following one: growth, chromosome replication, repair of chromosomal errors, and duplication of cell organelles. This is the right order in which these steps should happen before the cell is to reproduce or split itself into several parts during mitosis.
