Answer:
They may place a sterility indicator with special dye to detect the growth of endospores.
Explanation:
A sterility indicator should be placed inside and in the center of the item that will be autoclaved, if the indicator changes colors that means that the endospores were not killed with the sterilization process and the bacteria survived the high temperatures of the autoclave.
Answer:
4.2moles
Explanation:
"The answer to your question is 4.2 moles of H₂O
Explanation:
Data
moles of H₂O = ?
moles of C₂H₆ = 1.4
Balanced chemical reaction
2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O
Process
To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.
2 moles of C₂H₆ 6 moles of H₂O
1.4 moles of C₂H₆ x
x = (1.4 x 6) / 2
x = 8.4/2
x = 4.2 moles of H₂O"
During S phase stage of interphase the cells copy their chromosomes.
<u>Explanation:</u>
The S phase of a phone cycle happens during interphase, before mitosis or meiosis, and is liable for the amalgamation or replication of DNA. The cell makes an indistinguishable duplicate of every one of its chromosomes. Chromosomes are found inside the core of the cell and comprise of long strands of DNA that contain the hereditary data of the cell.
G2 stage: This happens after the DNA had been copied in S stage. At that point, at a basic point during interphase (called the S stage), the phone copies its chromosomes and guarantees its frameworks are prepared for cell division. The point of this procedure is to deliver twofold the measure of DNA, giving the premise to the chromosome sets of the daughter cells.
Answer:
Skin color, a polygenic trait, is also determined by environmental factors.
Explanation:
In humans, skin color or pigmentation is a polygenic trait and is also determined by environmental factors such as exposure to the sun.
Polygenic traits are the traits which are controlled by two or more genes located on different chromosomes. For example, height, skin color, and color of the eyes.
John and Pat carry identical DNA however they exhibit different interaction of the polygenes and working conditions (environmental factors). For example, John works in a movie theatre and thus does not have much exposure to sun whereas Par works on the beach which is an open area and thus experience a lot of exposure from the sun.
Exposure to the sun leads to the darker skin and thus polygenic interactions and different environmental conditions lead to the variation in skin pigmentation in John and Pat.
