Which source contains most of earths fresh water
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.

what physical traits were favored in the peppered moth species after the Industrial Revolution
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.
How do animals store energy
Answer:
Animals store their glucose subunits in the form of glycogen, a series of long, branched chains of glucose.
Explanation:
ANSWER:
Animals store their energy in glycogen form in the body. This energy has been stored in the body for later use to perform the various life functions.
EXPLANATION:
Animals obtain their energy from the food they take in so that the various metabolic processes of the body can be performed. When animals eat food, the glucose present in food is broken-down by "cellular respiration" into an energy molecule known as ATP. When "excess ATP and glucose" are present, these are converted to glycogen by the liver and stored in the body for later use.which is a purine base in dna
Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.

The spores release from the male cones
I NEED HELP ASAP
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.

The look of an organism according to its genes is called as phenotype of an organism.
Explanation:
The genetic makeup of an organism is usually called as the genotype whereas the physical morphological structure of an organism is termed as a phenotype of an organism. The phenotype usually depends upon the genotype of the organism; this genotype is not visible and hence cannot be known easily.
Whereas a phenotype is easily visible. To know the genotype of an organism the unknown organism should be crossed with a true breeding cross.
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)
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.

How does the acidity of soil affect flower growth?
Soil pH can affect plant growth in several ways. Bacteria that change and release nitrogen from organic matter and some fertilizers operate best in the pH range of 5.5 to 7.0 making this the optimum pH range. Plant nutrients leach from the soil much faster at pH values below 5.5 than from soils within the 5.5 to 7.0 range. In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. PH can also affect the structure of the soil, especially in clay soils. In the optimum range clay soils are granular and easy to work with. However, if the soil is either extremely acid or alkaline clay, soils tend to become sticky and hard to cultivate.
A pH soil test will tell you whether your soil is within the optimum range or whether it will need to be treated to adjust the pH level. Although the optimum range is 5.5 to 7.0 some plants will grow in a more acid soil and some at a more alkaline level.
PH is not an indication of fertility, but it does affect the availability of fertilizer nutrients. The soil may contain adequate nutrients yet plant health may be limited by an unfavorable pH level. On the other hand, builder’s sand, which is devoid of nutrients, may have optimum pH for plant growth.

What was the purpose of mendel’s experiments with dihybrid crosses
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 is Water source?Rainfall or melting snowfall is the source of practically all of the water supplies for human civilisation.
Rain that falls on land either evaporates to form streams and rivers or seeps into the soil to form groundwater. The sluggish subsurface movement of groundwater eventually causes it to resurface at the bottoms of lakes and rivers.
Every river or stream drains a certain portion of the land. The watershed of a river refers to the region of land that it drains. Drainage basins are another name for a watershed.
Therefore, Underground reservoirs and Melting snow and Surface-water runoff from rain are the sources of water in lakes.
