<span>A food handler is anyone who handles either
food or surfaces that are likely to be in contact with food such as plates,
bowls or cutlery. Therefore, he is responsible to ensure that food is safe to
eat, monitor a control such as to check and record food temperatures, keep
himself, his work clothes and work place clean. In addition, he need to report
any flu-like symptoms, skin infections, or open wounds. </span>
Answer:
B. into an aquifer
Explanation:
People can obtain groundwater by drilling a well into an aquifer.
An aquifer is a porous and permeable formation where groundwater can be found.
- Aquifer is usually found below the water table.
- In this regard, the pore spaces of this layer of the earth allows for the storage of ground water.
- When the aquifer is punctured, groundwater can be abstracted.
The answer is; D
A balanced equation is one that observes the law of thermodynamics on the conservation of matter and energy. Matter or energy cannot be created or destroyed but can only be transformed.
In this equation, therefore, the number of elements on the right side of the equation should match those of the left side. Of the choice equations, this is a balanced one; 6CO2 + 6H2O --> C6H12O6 + 6O2 and one that reflects the process of photosynthesis.
Answer:
Option 3, 20 or 22
Explanation:
A newly discovered species of dung beetle has 2n = 16 chromosomes. It mates with a closely related beetle species that has 2n = 12 chromosomes. How many chromosomes would there be in an allotriploid beetle produced from this cross?
- 40 or 44
- 20 or 22
- 20 or 22
- 36 or 48
- 40 or 44
Solution
An allotriploid is a species which contains three sets of chromosomes of different species .Crossing can result in triploid offspring with diploid gamete of one species and regular haploid gamete of other offspring
Case I - Resulting offspring (3n) = Gamete I (2n) + Gamete II (n)
OR
Case II - Resulting offspring (3n) = Gamete II (2n) + Gamete I (n)
Case I
Case II
Hence, option 3 is correct
Answer:
Here you go
Explanation:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
