What is unique about obtaining water from an artesian well?
O The water is heated by magma or hot rocks.
O The water is found in an impermeable layer.
O The water is under pressure naturally and no pump is needed.
O Amechanical pump must be installed to bring water to the surface.

Answers

Answer:

c-The water is under pressure naturally and no pump is needed.

Explanation:

Water from Artesian well is the water is under pressure naturally and no pump is needed.

What is Artesian well?

A well from which water flows under natural pressure without the need for pumping is known as an artesian well.

It is excavated or drilled whenever a gently sinking, permeable rock layer (such as sandstone) collects water at a level higher than the ground surface at the well site.

Water goes down into the aquifer (water-bearing layer) at the outcrop, but is blocked from escaping by impermeable rock layers above and below it (such as shale).

Water is forced to the surface of a well drilled down into the aquifer by the weight of the water (hydrostatic pressure) the pressure for the continuous up flow is maintained by the continued penetration of water into the aquifer at the intake region.

The ability to collect water is what distinguishes artesian wells.

The water is under pressure naturally and no pump is needed.

Pumping water isn't essential because there isn't any pressure in the water.

Hence, the correct option is C.

Receptors for hearing are found in the cochlea; whereas receptors for balance are located in the vestibule.

What is the inner ear?

The inner ear is a little structure in the ear composed of the Cochlea, Vestibule, and Semicircular canals.

This structure (inner ear) is responsible for both balance skills during movement and hearing sounds.

In conclusion, receptors for hearing are found in the cochlea; whereas receptors for balance are located in the vestibule.

which of the following can be changed during meiosis? Is it a base sequence, a number of amino acids, a number of chromosomes, or a gene sequence

Answers

Answer:

Number of chromosomes

Explanation:

Meiosis is a specialized type of cell division in which the gametes are produced.

A diploid parent cell first replicates its DNA. Then, two rounds of cell division occurs to produce 4 haploid cells, each with half the amount of chromosomes. These gametes fuse during fertilization to restore the diploid state.

Therefore, meiosis changes the number of chromosomes.

what do you think the rock in Earth’s mantle is like? Is the mantle made of hard, solid rock or soft, solid rock? Explain your ideas.

Answers

Answer:

If the mantle is made out of soft rock, then I think it would melt due to the heat, but if it was hard, it would just burn, so I firmly believe the rock is hard.

Explanation:

Mantle is a layer on planetary body which is made up of minerals. Mantle is solid as it is made up of heavy metals and solid rocks which makes it rigid.

What is Mantle?

A mantle is a layer inside a planetary body bounded by a core and on the above by a crust. Mantle is made up of rock or ices, and is generally the largest and most massive layer of any planetary body. Mantles are on the planetary bodies that have undergone differentiation by density.

The mantle is composed primarily of heavy metals, such as iron, nickel, and others. The state of the mantle was described as plastic. Many divide the mantle into further such as  the asthenosphere and lithosphere.

Mantle rocks are soft and able to move over the course of millions of years at great depth and pressure. The transfer of heat and material in the mantle helps to determine the landscape of the planet.

C. mitosis

Explanation:

Mitosis is one of the two types of cell divisions in which a single cell divides into two genetically identical daughter cells. Mitosis is used for growth and repair of tissues in living organisms.

Mitosis is also the process by which cells multiply/duplicate themselves. Hence, the process of a cell increasing its size, doubling its genetic contents, dividing into two independent cell, and repeating the process over and over again is called MITOSIS.

What information would best further the understanding of the relationship between the number of amino acid codons and their frequency in proteins?

Answers

Answer:

Explanation:

The information about the structure of a protein is key to understand its function and why certain codons are distributed the way they are. We know that proteins have several structures:

The primary structure, which is defined by the sequence of nucleotides in RNA.

The secondary structure, the regular arrangement of amino acids within located regions of the polypeptide. The most common structures are α-helices and β-sheets.

The tertiary structure, the folding of the polypeptide chain as a result of the interactions between the lateral chains of the amino acids that are located in different regions of the primary sequence.

The quaternary structure, which consists of the interactions between different polypeptide chains in proteins formed by more than one polypeptide, as is the case with hemoglobin.

We know that structure and function are strongly related to one another, and a crucial determinant for the tertiary structure is the location of the hydrophobic amino acids inside the protein and the hydrophilic amino acids on the surface, where they interact with water. The interior of the folded proteins are constituted mostly of hydrophobic amino acids organized in  α-helices and β-sheets, these secondary structures are located within the hydrophobic center of the protein. The bow regions that connect the elements of the secondary structure are located on the surface of the folded proteins, where the polar components form hydrogen bonds with water or with the lateral chains of the hydrophilic amino acids.

PLEASE HELP ME WITH THIS AND HURRY WILL MARK AS BRANLIEST!!!!!! Why do leaves change color in the fall? Research this phenomenon and write a two-page report describing what happens. Be sure to include an introduction and a conclusion to your report. Use the information you have learned in this lesson about chlorophyll, the green plant pigment, and its role in photosynthesis to help you explain what happens in the fall.​

Answers

Answer:

Leaves are always the color they turn in the fall

Explanation:

The chlorophyll created when the leaves use sunlight to create energy for the tree has a green pigment that covers the leaves actual colors. As the leaves separate from the trees they stop making chlorophyll, thus allowing the leaves true colors to return.

I hope this helps and good luck on that two-pager!

Answer:

During the fall the day gets shorter hence less sunlight this results to leaves stopping their food making process. The chlorophyll breaks down, the green color disappears and the yellow to orange color becomes visible

Why can’t a purine hydrogen bond with another purine within the sugar phosphate backbone of DNA? State your reason with all the details that are required to answer the question for full credit.

Answers

Answer:

due to the structural-binding properties of the nitrogen bases

Explanation:

Adenine and guanine are purines (two-carbon nitrogen ring bases) that pair with thymine and cytosine pyrimidine nitrogen bases (one-carbon nitrogen ring bases), respectively. These specific base-pair rules are due to their hydrogen bonds (i.e., van der Waals forces), which stabilize the structure of the DNA helix. Cytosine and guanine have three sites to form hydrogen bonds to each other, while adenine and thymine have only two sites. The specific interactions between purines and pyrimidines are critical for proper bonding and attachment to the sugar-phosphate DNA backbone (i.e., for the formation of the DNA double-helical arrangement).
