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
The food chain for the owl as secondary consumer would be grasses, mouse, owl. The food chain for the owl being tertiary consumer would be grasses, grasshopper, frog, owl.
Cytokinesis is when the cell pinches in 2 towards the end of meiosis and mitosis divisions. The chromsomes aren't as spread out and easy to see as during metaphase.
Meiosis is the whole process of producing gametes and not a stage/phase of division.
Mitosis is the whole process of cell division for growth and repair.
Metaphase is a particular phase in mitosis and meiosis where the chromosomes have been duplicated and are contracted and visible.
Thorax is the body segment of an insect supports the legs and wings.
Answer:
Muscles contract through a chain process of electrochemical signalling between the nervous system and muscles.
Explanation:
The muscle contraction is initiated by the nervous system by sending a signal. This signal also referred to as action potential travel through the motor neuron. This motor neuron releases a chemical signal to muscle when the electrical signal carried by it reaches the neuromuscular junction (a junction where motor neuron meets the muscles).
The chemical message referred to as neurotransmitter binds to the receptors present on the muscle fibers. These receptors causes the influx of sodium ion which in turn trigger the release of calcium ion thereby initiating the contraction of muscles.
