Temka [501]

Mitosis is a type of cell division for somatic cells and for the asexual reproduction of unicellular eukaryotic cells.

Meiosis is the type of cell division for the production of gametes in sexual reproduction . Meiosis is the process through which egg and sperm cells are formed. Mitosis is a necessary step for life.

A cell copies all of its components, including its chromosomes, and separates to generate two identical daughter cells during mitosis.

Meiosis is a form of cell division that occurs in sexually reproducing organisms and results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).

Mitosis is the division of a single cell into two identical daughter cells (cell division).

Mitosis is a kind of cell division that occurs in somatic cells as well as in unicellular eukaryotic cells during asexual reproduction. Meiosis is a sort of cell division that occurs during sexual reproduction to produce gametes.

What food allows bacteria to grow well?.
NemiM [27]

The temperature control for safety (TCS) food items like dairy products, eggs, meat, and poultry support the growth of bacteria, hence ideal for bacterial growth.

Foods that are more likely to become dangerous are referred to as TCS food. TCS food, in contrast to other foods, requires time and temperature controls to prevent the growth of bacteria. This cuisine has a pH that is either slightly acidic or neutral, contains protein, and is wet. Water is necessary for bacteria to break down the food they ingest in order to proliferate. Water that is not attached to food molecules can promote the growth of bacteria. Water activity or water availability refers to this unbound water. To grow, all bacteria require nutrients or an energy source. Carbohydrates, protein, sugar, and starch are a few nutrients. Milk and dairy products typically include a lot of nutrients, which makes them perfect for bacterial growth.

Which of the following is a sign of food spoilage?
grigory [225]

The sign that shows food spoilage is bulging or leaking cans. That is option C.

Food substances can be stored or preserved to prolong the nutritive values and shelf life of the food.

Food spoilage occurs when environmental factors such as:

  • Light,
  • oxygen,
  • heat,
  • humidity,
  • temperature and
  • spoilage bacteria

causes food to become unsuitable for consumption.

For canned products, bulging or leaking cans shows the food content has deteriorated.

This shows some ongoing fermentation by a spoilage bacteria causing the can to bulge and eventually leak out.

Therefore, the sign that shows food spoilage is bulging or leaking cans.
