Sam wished to investigate how fertilizer run-off affects the growth of algae in freshwater lakes and streams. He set his experiment up as follows. He placed 900 ml of water into each of five 1000 ml glass beakers. To each beaker, he added 5 ml of water from an aquarium which contained a large concentration of algae. The beakers were placed under a lamp which was on a timer to provide 12 hours of light each day. Liquid fertilizer was added to the beakers in the following amounts.
Each week, a random sample from each of the beakers was examined under a microscope to get a count of the number of algal cells present.

Question 5 of 10 Match each measurement tool with what it measures. Hygrometer ? Humidity Wind sock ? Air Pressure Barometer ? Wind speed and direction Anemometer ? Wind speed
Answer:
hygrometer measures humidity
barometer measures air pressure
wind sock measures wind speed and Direction
anemometer measures wind speed
The terms with their respective measurable device can be matched as:
1. Hygrometer is a type of device used to measure the content of water vapor or moisture in air or soil.
2. Barometer is a scientific instrument that is used for the measurement of air pressure. Temperature, wind patterns, and the earth's rotation affect the air pressure.
3. Windsock is a type of conical tube that is used to understand the direction of the wind. Windsocks are easily observed at airports and beaches.
4. Anemometer is a type of device, which consists of three spherical plates. The plates are used to measure the speed of the wind.
Thus, the quantities like air, moisture, and speed can be calculated by various instruments.

What theory’s/ideas challenge natural selection? In other words, what disproves natural selection?
Answer:
Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.

Explanation:
what is the point of human life, what is our purpose on earth and why were we put here?
Answer:
The purpose of creation for all men and women for all times has been one: To know and worship God.
The Qur’an teaches us that every human being is born conscious of God: “(Remember) when your Lord extracted from the loins of Adam’s children their descendants and made them testify (saying): ‘Am I not your Lord?’ They said: ‘Yes, we testify to it.’ (This was) in case you say on the Day of Judgment: ‘We were unaware of this.’ Or you say: ‘It was our ancestors who worshipped others besides God and we are only their descendants. Will you then destroy us for what those liars did’?” (Qur’an, 7:172-173)
In Christianity, the meaning of life is rooted in faith in the gospel of Jesus Christ. However, the proposition is not without serious problems.
First, if this is the purpose of creation and the precondition for eternal life, why was it not taught by the prophets to all the nations of the world? Second, had God turned into man close to the time of Adam all mankind would have had an equal chance to eternal life, unless those before the time of Jesus had another purpose for their existence! Third, how can people today who have not heard of Jesus fulfill the Christian purpose of creation? Naturally, such a purpose is too narrow and goes against divine justice.
The Prophet (peace be upon him) teaches us that God created this primordial need in human nature at the time Adam was made. God took a covenant from Adam when He created him.
God extracted all of Adam’s descendants who were yet to be born, generation after generation, spread them out, and took a covenant from them. He addressed their souls directly, making them bear witness that He was their Lord. Since God made all human beings swear to His Lordship when He created Adam, this oath is imprinted on the human soul even before it enters the fetus, and so a child is born with a natural belief in the Oneness of God. This natural belief is called fitra in Arabic.
Consequently, every person carries the seed of belief in the Oneness of God that lies deeply buried under layers of negligence and dampened by social conditioning. If the child were left alone, it would grow up conscious of God — a single Creator — but all children are affected by their environment. The Prophet of God said, “Each child is born in a state of ‘fitra,’ but his parents make him a Jew or a Christian. It is like the way an animal gives birth to a normal offspring. Have you noticed any young born mutilated before you mutilate them?” (Sahih Al-Bukhari, Sahih Muslim)
The Arabs would cut the ears of camels and the likes as a service to their gods in pre-Islamic times.
So, just as the child’s body submits to physical laws, set by God in nature, its soul submits naturally to the fact that God is its Lord and Creator. However, its parents condition it to follow their own way, and the child is not mentally capable of resisting it.
The religion which the child follows at this stage is one of custom and upbringing, and God does not hold it to account for this religion. When a child matures into an adult, he or she must now follow the religion of knowledge and reason.
As adults, people must now struggle between their natural disposition toward God and their desires in order to find the correct path. The call of Islam is directed to this primordial nature, the natural disposition, the imprint of God on the soul, the fitra, which caused the souls of every living being to agree that He Who made them was their Lord, even before the heavens and earth were created, “I did not create the jinn and mankind except for My worship.” (Qur’an, 51:56)
According to Islam, there has been a basic message which God has revealed through all prophets, from the time of Adam to the last of the prophets, Muhammad (peace be upon them). All the prophets sent by God came with the same essential message: “Indeed, We have sent a messenger to every nation (saying), ‘Worship God and avoid false gods...’.” (Qur’an, 16:36)
The prophets (peace be upon them) brought the same answer to mankind’s most troubling question, an answer that addresses the yearning of the soul for God.

Answer: The team that warms up will have there muscles warm and will do a better job during rowing and after theu are done they should stretch again.
Explanation:
The team warms up for thirty minutes and has better results in Olympics.
Why stretching is good before any strenuous activity?Stretching prior to exercise allows the muscles to loosen up and become resistant to the impact they are about to undergo, thereby reducing the chance of injury.
Your muscles and tendons will loosen as a result of proper stretching. During your workout, this will improve your flexibility and range of motion. Performance has improved. Stretching before a workout improves blood flow, suppleness, and range of motion, which boosts overall performance.

Answer:
You can actually apply the same concept, obviusly you want the cars to be the same weight, and you want your cars to be not too fast, because of the same equation F=MA if the car is faster, is because it has higher acceleration, wich results in higher impact force.
