Answer: Fish
Explanation:
Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.

Answer:
they use echos to communicate
Explanation: dolphins make echos in order to signal there partners, and others in there pod. or they can use it to signal for prey, or signal that they are in trouble.
Answer: A good example for this one is bats.
Explanation: While a couple of bats are known to emanate the beats through their nose, most bats will in general express them. The recurrence is estimated to be around 200 heartbeats each second, nonetheless, the time frame can fluctuate with the types of a bat. Credits: Adi Ciurea/Shutterstock A bat's squeaks are more rewarding than Ben's on the grounds that with higher recurrence comes higher-goal or more distinctive detail – they are equipped for evading deterrents no more extensive than a human hair! They use it to find and explore towards prey, for example, a hurrying bug. As the distinguished sound waves that structure the pictures are basically echoes, they should adjust to a standard — the recovered train of heartbeats should be sufficiently noisy to get back to the sender, yet short sufficient with the end goal that the reverberation of the sender returns before the following one withdraw.

Answer:
This is not a redox reaction.
Explanation:
A redox reaction is a reaction that involves reduction and oxidation processes. The best way to identify a redox reaction. Changes in the oxidation number f the species indicates that it is a redox reaction.
Na+
Reactant side = +1, Product Side = +1; No change
Cl-
Reactant side = -1, Product Side = -1; No change
Ag+
Reactant side = +1, Product Side = +1; No change
N
Reactant side = +5, Product Side = +5; No change
O
Reactant side = -2, Product Side = -2; No change
There is no change in any of the oxidation numbers, Hence this is not a redox reaction.

The diagram illustrates the water cycle.
Parts of the water cycle labeled U through Z. U: Water moving from a lake into the clouds. V: Clouds. W: Water falling from clouds as rain and snow. X: Water moving from ground to the clouds. Y: Water flowing down the mountainside into a lake. Z: Underground water going into lake.
Which process occurs at location W?
precipitation
evaporation
condensation
transpiration
Answer:
The Answer is Precipitation
Explanation:
Look it up on and then also got it right on the Unit Test and the Quiz.
The diagram illustrates the water cycle, the process that occurs at location W is precipitation. The correct option is a.
What is precipitation?Precipitation is any product of the condensation of atmospheric water vapour that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail.
Precipitation occurs when a portion of the atmosphere becomes saturated with water vapour so that the water condenses and precipitates or falls. Thus, fog and mist are not precipitation but colloids, because the water vapour does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapour to the air. Precipitation forms as smaller droplets coalesce via collision with other raindrops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers.
Precipitation is a major component of the water cycle and is responsible for depositing the fresh water on the planet.

Balance the chemical equation. Based on the equation, how many grams of bromine are produced by the complete reaction of 11 grams of potassium bromide?
Answer:
Explanation:
The balanced chemical equation is Cl2 + 2KBr → 2KCl + Br2. The amount of bromine is calculated as follows:
11.0 g KBr (1mol KBr/119.002g KBr * 1mol Br2/2mol KBr * 159.808g Br2/1mol Br2= 7.39 g Br2.)
Will the energy released in the synthesis of water equal the energy absorbed in the decomposition of water?
Answer:
yes
Explanation:
the energy released in the synthesis of water is equal to the energy absorbed in the decomposition of water. This outcome happens because the difference in energy between the reactants and the products in both cases is equal. . It follows the law of conservation of energy.

This is the type of wave that travels in one direction but the energy travels in the opposite direction
Answer:
Transverse wave
Explanation:
A wave is defined as a disturbance along a medium which transfers energy from one point to another.
A wave may be classified as transverse or longitudinal based on the direction of energy transfer relative to the direction of wave motion.
In a transverse wave, energy is transferred in a direction perpendicular to the direction of wave travel. Hence, the direction in which the energy travels is opposite to the direction in which the wave travels.

3. Why have we not been able to create a fusion reactor on Earth?
Answer:
We are not able to create a fusion reactor on Earth because fusion energy production is not based on a chain reaction, as is fission. Plasma must be kept at very high temperatures with the support of external heating systems and confined by an external magnetic field.

Calculate the average atomic mass for an imaginary element "E" that has the following isotope abundances:
56.67 % E-102.658 amu
43.33% E-104.770 amu
Answer:
Average atomic mass of E = 103.57 amu
Explanation:
Given data:
Average atomic mass of E = ?
Abundance of E-102.658 = 56.67%
Abundance of E-104.770 = 43.33%
Solution:
Average atomic mass of E = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass of E = (56.67×102.658)+(43.33×104.770) /100
Average atomic mass of E = 5817.63 + 4539.68 / 100
Average atomic mass of E = 10357.31 / 100
Average atomic mass of E = 103.57 amu.
