Answer:
Explanation:
This question appears incomplete. However, one of the main differences (in organelles) between plants and animal cells is the absence of cell wall and chloroplast in animal cells while both organelles are present in plant cells. The cell wall is outside of the cell membrane. The cell wall provides rigidity and support to the plant cell while the chloroplast is the cellular "machinery" for photosynthesis. The chloroplast contains the green pigment called chlorophyll which provides green plants with there colour and assist the plants in absorbing/capturing of sunlight/energy for the purpose of photosynthesis (self production of food by green plants).
Answer: Shale changes into Slate.
Explanation:
Shale is a sedimentary rock, formed by the deposition and compression of clay and silt.
Shale layers is buried deep into the earth through the process of deposition (i.e the laying down of rock forming material by natural entities like glaciers, wind, and water).
Temperatures and pressures rise greatly because the shale’s layers are buried. When the temperatures and pressures become higher. The shale is changed into a metamorphic rock (with dark brown streak), called Slate.
I believe it is the "myelin sheath." White matter = myelinated (has myelin sheath), while gray matter = unmyelinated (no myelin sheath)!
Answer:
It will take 83 days to recover the extra cost
Explanation:
To determine the length of time it will take to recover the extra cost, it will be logical that we compare the $200 extra cost to the total savings in running cost made for a year and covert this into days
The total savings in running cost is the cost savings per hour multiplied by the number of hours in a year.
The calculations are set below:
Savings in running cost per hour = $0.1
Total savings in a year = 365 days × $0.1 × 24 = $876
Extra cost of Energy Star refrigerator = $200
If total savings for a year is $876 , then equivalent length of time to save $200 would be
Length of time = 200/876 × 365 days = 83 days
It will take 83 days to recover the extra cost
