Answer:
1. Reverse Osmosis
Reverse Osmosis works by forcing feedwater through a semi-permeable membrane.
A pump is used to apply pressure to reverse the normal osmotic flow across a membrane, meaning purified water molecules (permeate) are forced through the reverse osmosis membrane and recovered in preference to contaminants in the concentrated side which are left behind (reject concentrate).
2. Oxidisation
Oxidisation in the form of chlorination has been used as a means of water purification since the beginning of the last century. Hypochlorite is the key agent, achieving a disinfection of water by oxidising bacteria to eliminate waterborne diseases. Several different methods can be used to provide oxidation, including ozonation, chloramination, UV, bromination & chlorine dioxide. During the treatment, hydroxyl radicals are generated to destroy bacteria cells.

What is the energy source for producers, consumers, and decomposers?
Answer:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Why do offsprings look different from there parents?
Living things produce offspring of the same species, but in many cases offspring are not identical with each other or with their parents. Plants and animals, including humans, resemble their parents in many features because information is passed from one generation to the next.
What is an example of a codominate
phenotype?
Answer:
With a codominant trait, phenotypes like fur color are combined. For example, if a black-feathered chicken breeds with a white-feathered chicken, their offspring will be both black and white. They will not be gray; rather, there will be spots of both colors. Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.

Which three organs are part of the digestive tract?
A) salivary glands, gall bladder, appendix
B)teeth, tongue, mouth
C)esophagus, stomach, small intestine
D)esophagus, liver, pancreas
Answer:
C
Explanation:
Due to the stomach and small intestine being part of the digestive tract and the esophagus allowing food, liquids and air to enter the torso
Esophagus, stomach, small intestine are part of the digestive tract. Therefore option C is correct.
The digestive tract, also known as the gastrointestinal tract, is responsible for the process of digestion in the human body. It consists of a series of organs that work together to break down food and absorb nutrients.
The three organs that are part of the digestive tract are the esophagus, stomach, and small intestine.
The esophagus is a muscular tube that connects the mouth to the stomach and helps in the transportation of food. The stomach is a sac-like organ that mixes and churns food with digestive enzymes and acids.
The small intestine is a long tube where the majority of digestion and absorption of nutrients occurs.
Therefore option C esophagus, stomach, small intestine is correct.

a sailboat moves faster as the wind blows on its sail. this is an example of acceleration, force, speed, velocity
Answer:
force
Explanation:
Gravity and buoyancy are the two key forces that operate on a stationary sailboat. The power of the wind pulls on the sail in order for the boat to move which allows the boat to move. The powers are now unbalanced, which is apparent from the acceleration of the ships.
The boat accelerates until the forward portion of the force from the sails is matched by the drag from the water.

How do cells obtain energy?
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.
This process is called 'cellular respiration'.
The process is happens in all the cells in our body.
Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

Answer:
There are many ways to save energy at home some are as following:-
1)Use Led Bulbs rather than Tubelight
2)Using Heater or Air Conditioner uses a lot of energy so we should reduce there usage
3)If possible, install a programmable thermostat to automatically adjust your home's temperature settings when you're away or sleeping.

Explanation:
other 2/4 will be carrier(Ss) and other 1/4 will have both dominant trait (SS)
Answer:
B. 1/2
Explanation:
The genotypes of the parents are Ss and Ss. We know this because Heterozygous basically means different alleles. The punnet square of this problem will show that the possible genes given to the offspring are SS (capital letters mean dominant. keep in mind that sickle-cell anemia is a recessive trait, meaning it is written in lowercase), Ss, Ss, or ss. So this means the offspring will have a 1/2 chance of becoming heterozygous (Ss).

Explanation:
A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.
What is Dichotomous key?More details regarding the unique characteristics of a given organism are disclosed with each successive division. Once the organism no longer exhibits all of the chosen traits in concert with any other organism, it has been recognized.
In order to identify specimens with a dichotomous key, it is recommended to employ immutable traits (i.e. features that do not change). Size, coloration, and behavioral habits can all change across people and over the course of a lifetime.
Better traits are produced by physical features (like the number of limbs) and biological processes (like the mode of reproduction). Typically, dichotomous keys are displayed in one of two ways.
Therefore, A dichotomous key is an identification technique that repeatedly divides groups of organisms into two categories.
