What is an ecosystem?An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Which organelle of a prokaryotic cell contains genetic information?
cell membrane
ribosomes
nucleus
nucleoid
Answer:
The right option is the 4 one. nucleoid
Prokaryotic cells are simple cells that lack a definite nucleus and some membrane-bound organelles. Prokaryotic cells have a nucleoid region, which is an irregularly-shaped central region of the cell that contains the cell’s genetic information (DNA). Other organelles that can be found in prokaryotic cells include plasma membrane, cell wall, cytoplasm, and ribosomes.

Calculate the vapor pressure (in torr) of a 35°C solution of ethanol and propanol where the mole fraction of propanol is .75. Assume Ideal behavior P°ethanol35=100torr P°propanol35=36torr
The vapor pressure (in torr) of a 35°C solution : 52 torr
Further explanationGiven
x propanol = 0.75
P°ethanol=100 torr
P°propanol=36 torr
Required
the vapor pressure
Solution
Raoult's Law
P solution = xA.P°A +xB.P°B
x ethanol = 1- 0.75 = 0.25
Input the value :
P solution = 0.25 x 100 + 0.75 x 36
P solution = 25 + 27
P solution = 52 torr

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.

What word is the biotic factor in this sentence:
Fish breath oxygen that is dissolved in water.
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.

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.

A boy sets up a picnic on the beach next to a sand dune. how are sand dunes formed?
Answer:
Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight.
