During the rainy season, rivers may overflow their banks, flooding the area and causing great damage. What is one thing people can do to help reduce the impact of flooding and subsequent erosion?
A number of different methods can be used to prevent the damage caused by flooding including vegetation to retain excess water, terrace slopes to reduce the slope flow, and building dams, reservoirs or holding tanks to store extra water during flood.
What is Flood?Floods caused due to overflow of river due to excessive rainfall causes river to exceed its capacity. Floodwater can also alter the landscape, by riverbanks and causing them to collapse. As floodwater carries materials from the soil, it suspends the sediment in the water, which will degrade the water quality and hence lead to harmful blooms of algae
The flooding of a river is an example of unsteady and non-uniform flow of water. There are many different types of flow includes steady flow in which the fluid characteristics like velocity (V), pressure (P), density (ρ), etc. at a point do not change with time.

what do a bacterium and a human being have in common?
Answer:
This means that the same codon "means" the same amino acid in all organisms. For example, in both humans and bacteria, a codon made of three thymine DNA-letters will code for an amino acid called Phenylalanine. ... This code is common to both humans and bacteria, and indeed, for most living things.

what is the colour change when universal indicator is added to apple juice
Answer: The color would be light red
Explanation:
Apple juice is derived from apples which are rich in vitamin C. Chemically, vitamin C is an acid called ascorbic acid and apple juice also contain acids like folic acid and Pantothenic acid.
Hence, it is to be considered as acidic in nature.
So that, pH of apple juice is found to be in the range of 2.9 - 3.5.
Hence, the Colour of pH will be Light Red

Microscopes are important tools. But do you know the difference between there microscopes and when to use each type?
The compound light microscope combines the power of lenses and light to enlarge the subject being viewed.
The stereo microscope allows an object to be viewed three-dimensionally under the lenses.
Very small, live cells, like bacterial cells should be viewed using a scanning electron microscope.
The scanning electro microscope produces high-resolution, sharp, black and white 3D images.
If your task was to dissect the mouth parts of a grasshopper, you would use a compound light microscope to assist you.
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light.
Answer:
A scope built of two systems of lenses ... ==> Compound light microscope
The light compound microscope is composed by two groups of lenses. In the first one, the lens projects a real intermediate image which is enlarged and inverted to the focal plane of the eyepiece. In the second group, the eyepiece that behaves like a magnifying glass, gives an image of the intermediate image which is enlarged and inverted again.
Designed for studying cells and tiny slices... ==> Transmission electron microscope.
The transmission electron microscope is an electron microscope for viewing objects much smaller than cells.
The transmission electron microscope (TEM or TEM) uses a high-voltage electron beam emitted by an electron gun.
If sample preparation is longer and more demanding than for optical microscopy, the resolution offers an incomparable view of the structures. Transmission electron microscopy allows to visualize intracellular organelles, viruses, crystals ...
A microscope that has lower magnifying power .... ==> Stereoscope (dissecting microscope).
The stereomicroscope is a special type of magnifying glass, often called a binocular loupe.
It is a device intended primarily for observation at low magnification with lighting overhead. It allows especially stereoscopic perception, in relief, of small subjects.
The stereomicroscope should not be confused with a microscope equipped with a binocular head. The latter only provides two identical images, with a "flat" rendering.
A microscope which magnifies from magnification ranging from 20X to 30.000X... ==> Scanning electron microscope
Scanning electron microscopy (SEM) is an electron microscopy technique capable of producing high resolution images of the surface of a sample using the principle of electron-matter interactions.
This microscope consists of an electron beam scanning the surface of the sample to be analyzed which, in response, reemits certain particles. These particles are analyzed by different detectors that reconstruct a three-dimensional image of the surface.

Land heats up faster during the day than water does. As the beach gets warm during the day, it heats the air above it. The warm air rises and cool air from the ocean is pulled in to
replace it. So, air flows from the ocean to the land. At night, the land cools faster than the ocean. What most likely happens to the air at the beach at night?
The air is still
The air moves along the coast
The air flows from the ocean to the land
The air flows from the land to the ocean. At night, the land cools faster than the ocean. What most likely happens to the air at the beach at night
Answer: I believe the ocean will be cool and the land will be cool so pretty much it will be more cooler at night than the day I hope this helps.

There were a large number of pure varieties and relatively short generation time. It was one of the few plants that can be grown in a garden as well as can self-fertilize.
Mendel select pea plants as a subject for his experiments because the flowers of pea plant are bisexual, self-pollinating means both male and female present on the same flower so self and cross-pollination can be done easily.
The different physical characteristics of the pea plant were easy to study. The garden pea had a relatively short generation time means it can complete its lifecycle in short period of time. It was one of the few plants that can be grown in a garden easily.

How frequently do warm interglacial periods occur?
Answer:
Warm interglacial periods occur every 100 000 years. We are currently in an interglacial period. Has Earth spent more time in cold ice age periods or in mild interglacial periods over the past 400 000 years? Over the past 400 000 years, Earth has spent much more time in Ice ages.
Explanation:
An interglacial period (or alternatively interglacial, interglaciation) is a geological interval of warmer global average temperature lasting thousands of years that separates consecutive glacial periods within an ice age.

What seems to be the best way to get the 'puck (point charge)' into the goal More charges in the field
Answer:
We can find the electric field created by a point charge by using the equation E=kQr2 E = k Q r 2 .
Explanation:
The electric field of a point charge is, like any electric field, a vector field that represents the effect that the point charge has on other charges around it. If the charge is positive, field lines point radially away from it; if the charge is negative, field lines point radially towards it.
