A possible hypothesis for this situation is that tank 1 contains denitrifying bacteria, tank 2 contains nitrite nitrifying bacteria, and tank 3 contains ammonia nitrifying bacteria.
What is a hypothesis?A hypothesis, which is a common term used in experiments refers to a possible explanation for the results or phenomenon observed. In this case, a hypothesis needs to focus on the type of bacteria that are present in each of the tanks.
This means that to write a hypothesis we need to relate the type of bacteria to each of the tanks.

Answer:
I think your answer is wrong. The right answer is D. Nucleus & Ribosome.
Explanation:
A process that takes place in the cells of all living things: the production of proteins. This process is called protein synthesis, and it actually consists of two processes — transcription and translation. During translation, the genetic code in mRNA is read and used to make a protein. These two processes are summed up by the central dogma of molecular biology: DNA → RNA → Protein. In eukaryotic cells, transcription takes place in the nucleus. During transcription, DNA is used as a template to make a molecule of messenger RNA (mRNA). The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs.
The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Typically, the nucleus is the most prominent organelle in a cell. Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

Explanation:
6:
Answer: Newton's first law of motion,
Explanation: Inertia is the tendency of an object to resist a change it its motion. Describe how inertia affects motion. If an object is already at rest, inertia will keep it at rest. If the object is already moving, inertia will keep it moving.
7:
Answer: The second law
Explanation: The second law shows that if you exert the same force on two objects of different mass, you will get different accelerations (changes in motion). The effect (acceleration) on the smaller mass will be greater (more noticeable).
8.
Answer: Newton's Second Law
Explanation: The second law of motion explains the relationship between force, mass, and acceleration. The law states that the acceleration of an object depends on the mass of the object and the amount of force applied. Newton's second law of motion is also called the law of force and acceleration.

Which of the following is not one of the seven primary odors humans recognize?
fresh
putrid
pungent
roses
Answers
Answer:
roses
Explanation:
It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.2 Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.3
There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease.
Answer:
Fresh
Explanation:
When you look at the chartr, Roses were cconsidered a floral scent, which was listed, then there was putrid, pungent, and 3 others, the only one that wasn't listed was fresh, because often out scent and taste work together to help us find rotten foods, but we find that by smelling putrid scents or pungent scents, rather than fresh scents. Therefor the correct response is fresh

in plants and animals
Answers
Answer:
MAIN DIFFERENCES
- During cytokinesis, animal cells undergo a narrowing in the center, which does not occur in plant cells.
- Once the process is finished, the plant cells are partially united while in the case of animals they remain separated.
- A fundamental difference is that in animals, cytogenesis occurs by strangulation, but this is not the case of plants, which is by septation.

which nutrients are present in solution x?
Answers
Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. They are used in every process of an organism’s body. Some of the processes are growth (building cells), repair (healing a wound), and maintaining life (breathing).
Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.
From these basic nutrients, plants and other autotrophs synthesize, or create, their own nutrients, such as sugars. The human body can also synthesize some nutrients, such as amino acids. However, most organisms need nutrients created by autotrophs. People and animals get most of their nutrients from food.
Essential nutrients are nutrients that the human body is unable to synthesize. They must be obtained from food or water. Essential nutrients include carbohydrates, proteins, fats, vitamins, and minerals.

Will pigs ever fly?
Support your answer with suitable examples.
Answers
Answer:
NO
Explanation:
the pigs will never be able to fly as the birds have:
wings – these enable the force of lift.
lightweight, smooth feathers – this reduces the forces of weight and drag
streamlined body – this helps reduce the force of drag (a shape that lowers the friction drag)
light bones – a bird’s bones are basically hollow with air sacs and thin, tiny cross pieces to make bones stronger – this reduces the force of weight
Meanwhile the pig is obviously heavier, having a stronger force of gravity, and does not have the same type of "lightweight" bones that the birds have.
Answer:yes they might
Explanation:
Birds are able to breed with pigs and pigs might get wings
