Which source contains most of earths fresh water
Answers
Answer:
A large portion of Earth's crisp water is secured away in the polar tops. A large portion of the rest is ground water. All things considered, there are three primary wellsprings of crisp water: groundwater, the water in lakes and waterways and the water tied up in the strong state as ice.
Fresh water is the water found either in the form of liquid or ice, which has low content of salts. Lakes, river, ponds, glaciers, are some examples of fresh water bodies.
The majority of the world's fresh water is stored in icecaps and glaciers.

I NEED HELP ASAP
Answers
Answer:
The gametophytes grow directly from the sporophyte - third choice
Answer:
The correct answer is The gametophytes grow directly from the sporophyte.
Explanation:
Conifers are a group of plants that belong to what is called Pinophyta.
They abound in quantity in cold areas although many different types of this plant can also be found in tropical areas.
They are formed by live gemnosperm plants, this means that their seeds do not form in closed cavities but are "naked". These seeds are evergreen, this means that their leaves will not fall throughout the year and usually live for more than two years or produce other seeds again.
Gametophytes are haploid plants that are usually located in or below the soil and are responsible for producing gametes.
These grow directly from the sporophyte, which is the phase in which a plant reproduces by spores.
So we can say that the correct answer is The gametophytes grow directly from the sporophyte.

What was the purpose of mendel’s experiments with dihybrid crosses
Answers
Final answer:
Mendel's experiments with dihybrid crosses were conducted to test the hypothesis of independent assortment. He crossed pea plants with different pairs of traits to determine if these traits are inherited together or independently. The results showed that traits segregate independently during sex cell division, leading to Mendel's law of independent assortment.
Explanation:
Mendel's experiments with dihybrid crosses had the purpose of testing the hypothesis of independent assortment. By crossing pea plants with different pairs of traits, such as yellow round seeds and green wrinkled seeds, Mendel was able to determine if these traits were inherited together or independently.
The results of his dihybrid crosses showed that traits segregate independently during sex cell division. This led to the formulation of Mendel's second law of inheritance, known as the law of independent assortment.
what physical traits were favored in the peppered moth species after the Industrial Revolution
Answers
Their skin color was dark which made the moths blend in. During the Industrial Revolution, the soot from factories caused the trees to become black. The light colored moths became easier to kill because they could not blend into their environment.
Answer:
Dark Skin Color
Explanation:
After the industrial revolution, the tree trunks got covered with dark soot and the lichens present on these tree trunks were killed. Under these polluted conditions, the dark-colored moth could blend themselves easily with soot-covered tree trunks. Hence, these dark-colored moths exhibit better survival and reproductive rate than the light-colored moth population.
So, natural selection favored light skin color after the industrial revolution.

Explanation:
Answer: From birth to three years old they produce 700 neural connections. A baby has 100 billion neurons. It multiplies to trillions at two years old, most probably at three it would be quadrillions.
Explanation: Babies are born with billions of brain cells, and by the time they are three years old, they have formed trillions of brain connections. This rapid increase in brain connections is a result of the brain's remarkable ability to adapt and change in response to experiences. As babies interact with their environment, engage in play, and receive nurturing and stimulating experiences, their brain cells form new connections, creating a complex network of neural pathways. The exact number of brain connections varies between individuals, but it is estimated that by the age of three, a baby's brain can have trillions of connections. These connections are essential for cognitive development, learning, and the foundation of future abilities and skills.

How do you extract the oil from the fruit of the Tung tree?
Answers
Answer:
Tung oil is made from pressed seeds from the nut of the tung tree. The tung tree, native to China, is named for its heart-shaped leaves because “tung” is Chinese for “heart.” In the 14th century, Chinese merchants were noted for using tung oil to waterproof and protect wooden ships from the eroding powers of the sea. There are even mentions of tung oil appearing in the writings of Confucius in around 400 B.C. For these reasons, it is also sometimes referred to as “China wood oil.
Explanation:
To extract oil from Tung tree seeds, the seeds are either pressed or crushed, or, for more efficiency, a solvent like n-hexane is used. The solvent is then distilled off, leaving the Tung oil. Traditional methods might involve boiling and skimming the oil from the surface.
Initially, Tung fruit is harvested and the seeds inside are collected because the oil is contained within these seeds. The seeds might be dried and then crushed or pressed to release the oil. However, for higher efficiency, chemical solvents such as n-hexane can be used to extract the oil from the seed material. After extraction, the solvent is distilled off, leaving behind the Tung oil, which can then be further processed and purified.
The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angles of the pentagon are equal, which expression represents the measure of two angles?
2x2(20 – 32x + 25x2)
2(8x2 – 13x +10)
5x2(8x2 – 13x + 10)
5(3x2 – 8x + 5)
Answers
Answer:
2(8x^2-13x+10)
Explanation:
There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.
Let's let A represent the measurement of one of the those angles in our pentagon.
The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.
But we are also given that this equals 40x^2-65x+50.
So that means 5A=40x^2-65x+50.
If we divide both sides by 5 we can find what one of our angles is in terms of x. So let's do that A=8x^2-13x+10.
So we want to know the sum of two our angles, we want to know what is A+A or 2A. 2A=2(8x^2-13x+10). To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.

1. Do you think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved? Why or why not? Think about your opinion and then back it up with at least one fact. (10 points) APEX
Answers
Answer:
Yes, I agree that the discovery of DNA model by Watson and Crick took help from the work of many other scientists which were not credited with the discovery as much as both of them were credited.
Explanation:
One of the major breakthroughs made in the discovery of DNA structure was the work of a female scientist, Rosalind Franklin who did X-ray crystallography according to which DNA was helical in shape. Watson and Crick took strong support from this theory and proved that DNA was helical in shape. However, she was a perfectionist and she had not published her work yet while the Watson and Crick were fast enough to do so. Before that Watson and Crick while working independently formulated incorrect DNA models in which bases were placed outside while phosphate groups were outside. However, Rosalind Franklin's work was of substantial help to both of them. There was another colleagues of Franklin, Maurice Wilkins who was working with Franklin in doing X-ray studies. n 1962 Watson, Crick, and Maurice Wilkins were jointly honored with the Nobel Prize in medicine for their model of DNA in 1953 but she was not nominated for Nobel price because it could only be shared by three scientists maximum and Franklin was died by that time too.
Therefore, i think it was not fair with Franklin that she never received the credit of the work which she did tirelessly and which became basis of modern DNA model.
Hope it helps!
No, it is not fair that Watson and Crick were only credited with the discovery of the DNA model.
What is Watson and Crick's model of DNA?Watson and Crick proposed a model of DNA in 1953 which is semi-conservative in nature. This model of DNA has a double helix that is bound together with the help of units known as bases.
During the time of Watson and Crick, Erwin Chargaff proposed the rule of base pairing which is also seen in Watson and Crick's model of DNA. According to him, the amount of adenine is always equal to the amount of thymine, and the amount of guanine is always equal to the amount of cytosine.
[A] = [T] and [G] = [C]
Therefore, Watson and Crick were not the only ones who were credited with the discovery of the DNA model.

Explanation:
Diffusion occurs when molecules move from an area of high concentration to a low concentration until equilibrium is achieved. This does not require energy because it is a spontaneous process. This also included osmosis when there’s a difference in the concentration of solutions across a semipermeable membrane, water molecules move from the low concentration the solution to high concentration until the two solutions are isotonic to each other.
To move molecules against a concentration gradient, energy must be expended. In cell this is through the energy of ATP molecules.

Surface currents are a result of all of the following except
the moon’s gravitational pull
shape of the ocean basins
global wind patterns
Earth’s rotation
Answers
Answer:
the moon’s gravitational pull
Explanation:
Surface currents are a result of all of the following except the moon’s gravitational pull.
Surface currents are created by "global wind patterns", Earth's rotation, and the shape of ocean basins, but not by the moon's gravitational pull, which instead affects tides.
Surface currents in the ocean are a result of several factors, but not the moon's gravitational pull, which primarily affects tides rather than surface currents. The main drivers of surface currents include global wind patterns, Earth's rotation, which contributes to the Coriolis effect, and the shape of ocean basins. These currents are responsible for distributing heat around the planet and have a significant influence on the climate. It is the tides that are affected by the moon's gravity, whereas surface currents are influenced by other factors.
