When an animal eats, food stays in the stomach for a period of time. When a unicellular organism, such as paramecium, takes in food, the food is contained in which organelle?.
When a unicellular organism, such as a paramecium, takes in food, the food is contained in a specialized organelle called the "food vacuole." The food vacuole is a membrane-bound sac within the cytoplasm of the unicellular organism.
Phagocytosis is the process by which the unicellular organism surrounds and engulfs solid particles, such as food particles or other microorganisms, forming a food vacuole. It forms by engulfing and enclosing the food particles during the process of phagocytosis, which is a type of endocytosis.
Once the food vacuole is formed, it fuses with lysosomes (organelles containing digestive enzymes) to digest the ingested food and break it down into smaller molecules. These smaller molecules are then used for various cellular processes, including energy production and growth, within the unicellular organism.

Explanation:
What is the probability that a color blind woman marries a man with normal vision will have a color blind boy
Answer:
100%
Explanation:
The gene for color blindness is carried on the X chromosome. A woman who expresses the trait for color blindness has two copies of the allele for color blindness, one on each X chromosome. Since it is not carried on the Y chromosome, and boys always inherit their X chromosomes from their mothers, a son can only inherit a X chromosome with the allele for color blindness, meaning any son from this woman will be color blind.
Answer:
1/2
Explanation:
It depends on the hereditary gene that will dominate, whether the colour blindness or normal vision

What procedure did you use to complete the lab
The Lab Name Is Energy Transfer.
Answer: Energy transfer could come through condoctours (metal, or copper) to another object to power a bulb, speaker or any other electrical gizmo. (This can get a brainliest answer)
Answer:
Energy transfer is a process of passing energy into a source that lacks it, like a lightbulb. Energy can be transferred through conductors, that pass through the energy to the goal (lightbulb). Conductors are available inside of the cables you use to connect the power source and the lightbulb together, they are mostly metals, since they are good conductors. When you turn on your lightbulb, with it connected to the cable which is connected to the energy source, the energy passes through the conductor into the goal and turns on your lightbulb. There are other products to prevent energy transfer, they are called insulators, they stop energy transfer and keep it stored inside of them. An example of insulator is silicon, it stores the energy instead of transmitting it and keeps it stored inside without electrifying anyone when touching it.

Describe the exchange of co2 and o2 the lungs
Explanation:
Co2 and O2 in the lungs are exchanged when alveoli send oxygen to the capillaries surrounding them to the nearby blood vessels which contain c02, and osmosis occurs where o2 is now in the vessels while co2 is now in the alveoli and therefore the lungs, and then the co2 is expelled out of the lungs.

Sea otters tend to inhabit the shores of the pacific (sometimes rivers, ponds, or lakes), a favorite habitat is the kelp forests on the coast of California. Mother otters even tie their babies (and sometimes themselves) in kelp leaves, keeping them near and preventing floating away when diving for food. This is a clear sign of intelligence, and they classify as mammals. Otters stay in groups led by a dominant male, but sometimes females will leave with their babies, or males will depart in search of their own group to manage.
