Answer: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle.

Answer:

Incomplete Dominance

Explanation:

When two organisms that are true-breeding for different colors are bred, their offspring will show incomplete dominance. This will result in the offspring having all grey feathers. In the attached punnet square, a true-breeding red flower (R) and a true-breeding yellow flower (R') are bred to produce 4 orange offspring (RR').

Codominance makes offspring display both phenotypes separately. So, the chicken babies would have white and black feathers, no grey.

Complete dominance would be if one allele dominated the others. For example, if all of the whitexblack chicken babies were black

Simple dominance is when a gene is controlled by only two alleles, one dominant and one recessive, and shows complete dominance.

State three reasons for preventing food spoilage​
bogdanovich [222]

Answer:

1) Refrigerate or freeze

If you freeze or refrigerate the food, the bacteria or whatever organism growth will slow down in the food by a Greta amount due to the coldness. Refrigerate might be a temporary food soteage for like a week or 2/ month max. While freezing will just freeeze the bacteria and mold on the food which can be stored up to 3- 12+ months even. But then again it will be most likely flavorless by the end or have no nutrients value. You can stores mik in the freezer for a while but its not recommended to taste, same for other thing syou usually see in the fridge, eggs/ vegetables/fruits/ milks/ yogurts/ etc.

2) No moisture, no water of any kind (drying in the sun or salted)

So every living thing we know of needs water. Including bacteria and mold. Without water, theres no place to thrive. No place to thrive means no bacteria and food is safe for a good amount of time. Dried foods can last a really long time, sure some types are really unpleasant but its edible. But you can’t techincally “dry” meat since it will be A whole nest for flies before it even reaches the halfway mark. You can slat it which will lessen he time but still really efficient. Salt absorbs water and breaks down any type of Stuff. Its like a mini acid.

3) Canned good and no air access (Pressurized/ controlled container)

This is done by putting all your favortie food in a metal container. With no air access, the bacteria or mold in the food already in can’t escape and new ones can’t get in. THe can then is boiled to a certain tempature where then the bacteria dies. Now the food can even be perishable stuff like meat (most common fishes), fruits and even a nice can of liquid soup. Nothin g can get in. Nothing can get out but nothing CAN get out becuase eveythign is dead. Canned food can last REALLY LONG, good for long term expeditions without a fire or food.
