What is Flood?Flood is defined as a natural disaster which results from the overflow of water on land. It is mainly generated by the heavy rainfall, sudden snow melt, etc. It affect the ecosystem adversely.
The floods are mostly affected to the coastal regions. It is even a threat to life of people. The habitat of aquatic organisms are destructed by the floods. The ground water is found to be contaminated with pathogenic microbes and causes water borne diseases.
As a result of floods the life of small insects which play a primary role in the ecosystem of food chain is also affected. All fields like education, communication, transport, etc. of our state is affected by the floods.
The floods can cause loss of people, low water quality, destruction of habitats. Some times the effect of flood in our life will be long lasting.
Thus the correct option is D.

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.
Explanation:
Answer:
nucleoid

How many moles of oxygen are in 2.00 moles of NaCIO4?
Answer: 8 Moles of Oxygen
Explanation: The formula shows that there are (exactly) 4 oxygen atoms in each mole or formula unit. Therefore 4 * 2.00 = 8.
What mass of oxygen combines with 2.81 mol
of magnesium in the reaction
2 Mg(s) + O2(g) → 2 MgO(s)?
22.48 g. mass of oxygen combines with 2.81 mol of magnesium in the reaction. For the reaction 2 Mg(s) + O2(g) → 2 MgO(s).
What do you mean by molar mass ?The term molar mass is defined as the mass of 1 mole of that particular substance and number of grams per mole of a compound.
In other words, the molar mass is the total mass in grams of all the atoms that make up a mole of a specific molecule. As a result, the molar mass units are grams/mole.
The balance chemical equation is as follows :
2 Mg(s) + O2(g) → 2 MgO(s)
The metal Mg reacts with Oxygen in a 2:1 ratio you would divide 2.81 by two.
Now, we get,
2.81 / 2 = 1.405
You would then multiply 1.405 by the molar mass of Oxygen which is 15.999
= 1.405 × 16
= 22.48 g.
Thus, 22.48 g. mass of oxygen combines with 2.81 mol of magnesium in the reaction.

1pt Which of the following is NOT true about the role tectonic forces play in the rock cycle?
O A. When plates pull apart, rocks melt, and magma forms igneous rocks.
O B. When plates crash together, rocks are buried and form metamorphic rocks.
O c. When plates slide over and under each other, the heat and pressure form igneous rocks.
OD. When rocks push upward and form mountains, the erosion of the mountains can produce sediment.
Tectonic forces do not cause plates to slide over and under each other, to produce heat and pressure which forms igneous rocks
What is the rock cycle?The rock cycle is a cycle which describes how the three basic rock types are related and how earth processes convert one rock type into another over geologic time.
Plate tectonic forces together with weathering and erosional processes, are responsible for the rock cycle.
Tectonic forces play the following roles in rock cycle:
When plates pull apart, rocks melt, and magma forms igneous rocks.When plates crash together, rocks are buried and form metamorphic rocksWhen rocks push upward and form mountains, the erosion of the mountains can produce sedimentTherefore, the statement that when plates slide over and under each other, the heat and pressure form igneous rocks is not True.

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.

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.

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

When chlorine is added to sodium bromide solution, the mixture turns brown. What type of reaction has taken place?
Answer:
A displacement reaction
Explanation:
This is because the chlorine reacts with the sodium bromide, forcing it to go brown.
I hope this helps, good luck! (✿◡‿◡)
When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine.
What do you mean by Solution?In chemistry, a solution is a homogeneous mixture of two or more compounds in their relative proportions that can be continually altered up to what is referred to as the limit of solubility.
Although the word "solution" is typically used to refer to the liquid state of matter, solutions of gases and solids are also possible.
When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine. Because chlorine is more reactive than bromine, sodium bromide loses its bromine content. The mixture darkens to brown. The bromine has been displace, giving this colour of brown.

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.
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.
