Answer:
Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.
Explanation:
Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.
Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.

Does a virus have an independent lifecycle?
1. Describe the structure of DNA.
2. What does a nucleotide consist of?
3. What are the base-pairing rules?
4. If one DNA strand reads CCGTAATGCAT, what will be the sequence of the
complementary strand?
Answer:
DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

Answer:
toward the origin of replication
Explanation:
A replication fork is a structure formed during DNA replication when specific enzymes (i.e., helicases) separate both DNA strands at the origin of replication. DNA is always synthesized in the 5' to 3' direction, thereby DNA can be synthesized continuously on the leading strand, because the growth of this strand proceeds in the same direction as the movement of the replication fork, while DNA synthesized in several short segments on the lagging strand which are called 'Okazaki fragments'. DNA polymerases are enzymes that can only add nucleotides to the 3' end of a DNA strand, thereby they require the synthesis of short stretches of RNA or 'RNA primers', which are necessary for DNA replication of the lagging strand.
1. Compare gaseous biogeochemical cycle and sedimentary biogeochemical cycle.
Answer:
Gaseous cycles include those of nitrogen, oxygen, carbon, and water; sedimentary cycles include those of iron, calcium, phosphorus, and other more earthbound elements. In a sedimentary cycle elements move from land to water to sediment. Main reservoirs are the soil and sedimentary rocks.

Which statement best explains the difference between water temperature at
the poles and water temperature at the equator?
O A. The water is denser and saltier near the equator, so it holds more
heat.
B. The sun's rays strike the water at an angle at the poles.
C. Deep sea vents pump steam into the conveyor belt near the
equator.
D. Due to Earth's rotation, gyres near the poles flow clockwise.
Answer:
B. The sun's rays strike the water at an angle at the poles.
Answer:
b
Explanation:
At high latitudes, ocean waters receive less sunlight – the poles receive only 40 percent of the heat that the equator does. These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold -2°C (28°F) near the poles

During a dry year, which plant will most likely be able to survive in clay soil?
Answer:
A
Explanation:
Answer:4
Explanation:
The weight of body is 420 N . Calculate it's mass..
Here,
Force = 420N
Gravity = 9.8m/s^2
Mass = ?
Now,
Force = Mass * Gravity
420 = Mass * 9.8
420/9.8 = Mass
Mass = 42.85Kg

Depletion of nonrenewable resources is often a result of:
1)environmental laws
2)human population growth
3)reforestation
4)recycling
Answer:
Depletion of nonrenewable resources is often a result of reforestation.
Answer:
2 -- Human Population Growth
Explanation:
The rest have no effect on nonrenewable resources because they are renewable, or replenishable. The more humans expand, they more resources they need such as gas, coal, and oil. Due to the fact that resources such as those listed before can't be renewed, or replenished, it causes a loss in those resources (depletion).

2) What does a negative velocity in UAM mean?
3) When you toss a ball into the air expecting it to hit the ground later, when will the ball achieve its
highest velocity? highest acceleration?
4) Suppose you drop an object both on Earth and on the moon, how do you compare its velocity on
Earth and on the moon?
PASAGOT PO BADLY NEEDED
Answer:
the negative distance in UAM indicates left side and downward movement of an object.
Explanation:
The negative distance in uniformly accelerated motion (UAM) indicates that the object is moving to the left side in Horizontal ( UAM ) and the object is moving downwards in Vertical ( UAM ). A positive velocity means that the object is moving in the positive direction, is related to the coordinate system, while a negative velocity means the object is traveling in the opposite direction. The velocity of an object on the moon is very low because the force of gravity is 6 times lower than earth so velocity of an object on the earth is higher than on the moon.

Question 3 of 10
The surface area of a sphere can be approximated as follows:
Surface area = 411/2;
where ris the radius of the sphere;
Ti is a constant that is roughly equal to 3.
Using the simple approximation above, calculate the surface area of a sphere
with a radius of 5 meters.
A. 500 m2
B. 900 m2
C. 3,600 m2
D. 300 m2
Answer:
D. 300 m²
Explanation:
A sphere is a three dimensional object with a surface which as like that of a ball. A sphere is a set of points that are all at the same distance r from a given point in a three-dimensional space.
The surface area of a sphere is:
Surface area = 4πr²
where r is the radius of the sphere, π is a constant = 3
Given that r = 5 meters, hence substituting into the area equation:
Surface area = 4π(5)² = 4(3)(5)² = 300 m²

describe how potatoes and eggs might have been digested with the help of enzymes.
The potato can make you feel at home in any part of the world. According to the International Potato Center, the potato is the third most grown crop in the world, with more than 300 million metric tons produced annually. The United Nations declared 2008 as the International Year of the Potato because of its importance in feeding the poor and hungry. If not deep-fried and loaded with butter or cheese, potatoes have a lot to offer nutritionally, and they are easy to digest as well.
Salivary amylase, an enzyme secreted with the saliva, acts at the long polysaccharide units that make up starch, to shape disaccharides known as maltose. The action of salivary amylase keeps until the potato reaches the belly.
How are eggs digested?The belly empties the chyme containing the damaged egg pieces into the small intestine, where the general public of protein digestion occurs. The pancreas secretes digestive juice that consists of extra enzymes that in addition smash down the protein fragments.
Digestive enzymes play a key position in breaking down the meals you eat. those proteins accelerate chemical reactions that turn vitamins into substances that your digestive tract can take in. Your saliva has digestive enzymes in it. Some of your organs, consisting of your pancreas, gallbladder, and liver, additionally release them.
