Answer:
evolution
Explanation:
For example, scientists believe that monkeys have evolved to become humans.
This clearly has happened over many millions of years.
Monkeys look really different from humans (don't you think!?).
This was just a random example that came to my head.
Hope this helps.
-Gumina
Answer:
She will add color dye to antibodies, and the antibodies will attach to the antigen of the pathogen.
Explanation:
Immunostaining is the process where the antibodies for a specific pathological antigen is combined with fluorescent dye or any other indicator, like enzyme. Fluorescein are common staining materials used because it is easily detectable under UV light. This antibody coated with indicator thus bind to the specific pathogen or protein and help in its identification. Also the pathogenic cell fixation is done to facilitates clear and precise identification.
Phospholipids will form a bilayer in water because they contain hydrophobic (Water fearing.. in this cause water "hating") tails and hydrophilic heads (water loving). So they form a bilayer to remove the tails from water likewise, this satisfies the hydrophilic heads because they are still exposed to water.
Plant tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis - Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue - The primary components of vascular tissue are the xylem and phloem.
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
