Answer:
As the water flows down, it may pick up more water from other small streams, springs or or from rain or snow melt. ... Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.Water can be introduced into rivers and streams through surface runoff, springs, groundwater discharge, melting ice and snow, and precipitation. ... The water at the source of the river has high oxygen content, but the width and depth are typically less than they are in the middle sections. The most simplistic answer is that all the water in a river comes from the sky—and that is certainly true, as streamflow is one part of the water cycle. It is also true that most of the water flowing in rivers comes from precipitation runoff from the surrounding landscape (watershed).

Which list correctly orders the forms of radiant energy by increasing
wavelength?
A. infrared light, radio waves, ultraviolet light, visible light
B. visible light, ultraviolet light, radio waves, infrared light
C. radio waves, visible light, ultraviolet light, infrared light
D. radio waves, infrared light, visible light, ultraviolet light
Answer: Option D.
radio waves, infrared light, visible light, ultraviolet light.
Explanation:
Radiant energy is energy electromagnetic radiation that travels by waves or particles. It is measure in Joule. There are different type of electromagnetic radiation and they are defined by the amount of energy, photons and wave lengths.
Radio waves have photons with low energies and wavelengths, microwaves have little, infrared waves have more than the two, ultraviolet have more, x rays have more energy photons and wavelengths, then gamma rays have more.
A gene mutation is a change in the sequence of nucleotides that occurs during cell replication (mitosis and meiosis) within a single coding section of DNA. Mistakes can also occur in the transcription of mRNA or the translation of a polypeptide. However, these changes are not considered to be mutations, because they are not permanent changes to the cell. Explain why "mistakes" in transcription or translation are not as serious as mutations in a gene.
Answer:
The cell has an elaborate mechanism in place that check for and correct the mistakes that happen during replication, transcription or translation. This process is called as proofreading. The incorrect nucleotide added during replication cause the replication to be halted for a while. The DNA polymerase enzyme fixes the error and replication then resumes as normal.
Gene mutation, on the other hand, is a permanent change in the DNA sequence that might lead to cancer.

Consider a melt that has cooled to a temperature such that olivine, pyroxene, amphibole, and calcium-rich plagioclase feldspar have crystallized. which elements will be enriched in the melt, and which will be depleted in the melt?
Answer:
Calcium is enriched, while they are depleted of carbon.
Explanation:
It should be understood that during the process of volcano eruption, carbon is liberated as the molten magma is coming out , this is due to the heat that is being evolved. And calcium will be the molecules that will make the molten solidified after wind has cooled it down.
That is why they are depleted of carbon, and enriched with calcium.

Carbon in the ocean originates from the atmosphere.
lease select the best answer from the choices provided
true or false
Answer:
true
Explanation:
Carbon in the ocean originates from the atmosphere; that is true as the carbon in the ocean's main source is the atmosphere, where carbon dioxide (CO2) dissolves into the surface waters of the ocean through a process called gas exchange.
What is the role of carbon ?Carbon is an essential element for life on Earth, and it cycles through various reservoirs such as the atmosphere, ocean, land, and biosphere, the ocean is a major carbon sink, meaning it stores large amounts of carbon. But carbon dioxide is a greenhouse gas that is naturally present in the atmosphere, and its concentration has increased significantly over the past century due to human activities such as burning fossil fuels that harm all living organisms.
As a result, carbon in the ocean comes from the atmosphere; this is true.

7. A type of cell division that results in diploid cells: [meiosis / mitosis
Answer:
Mitosis
Explanation:
Mitosis is a cell division process. The 2 cells created are exactly the same, and they have the same number of chromosomes. The result is two, identical, diploid daughter cells. Diploid means that there is 2 complete sets of chromosomes, and one complete set of chromosome pairs.
Meiosis is another cell division process, but the cells created are different from those in mitosis. There are 4 cells created, not just 2. Additionally, the cells produced are not identical. There is variation in the genetics of the daughter cells. This process creates haploid cells, meaning there is only 1 complete set of chromosomes, or half of a complete set.
Therefore, the cell division that results in diploid cells is mitosis.
The type of cell division that results in diploid cells is mitosis. Mitosis is a fundamental process in which a single cell divides into two identical daughter cells, each containing the same number of chromosomes as the parent cell.
The daughter cells produced through mitosis are genetically identical to each other and to the parent cell. Mitosis is involved in the growth, repair, and maintenance of tissues in multicellular organisms. It ensures that the body's cells retain the same genetic information and have the appropriate number of chromosomes (diploid) characteristic of the species. In contrast, meiosis is a specialized type of cell division that results in the formation of haploid cells, which have half the number of chromosomes as the parent cell.
Therefore, the type of cell division that results in diploid cells is mitosis.

how are the inorganic and organic fertilizers important in agriculture?
Answer:
It helps grow food and large amounts of it to feed the nation!
Explanation:
Fertilizer maintains the soil fertility, so the farmer can continue to grow nutritious crops and healthy crops. Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Most farmers today use fertilizers that are either mined or manufactured.
Answer:
In addition to releasing nutrients, as organic fertilizers break down, they improve the structure of the soil and increase its ability to hold water and nutrients. Over time, organic fertilizers will make your soil–and plants–healthy and strong.

The yellow ring inside the bacterial cell represents the bacterial DNA. Why does this structure disappear by step 3(this is when replication of viral nucleic acid and protein and envelope.) of the lytic cycle?
Answer:
When the virus injects it’s nucleic acid into the cell it uses the cell’s ribosomes to make virus proteins and those proteins are the main cause for the break up of the cell’s DNA.
The bacterial DNA structure will disappear because of ; The usage of the ribosomes of the bacterial cell by the nucleic acid injected by the virus.
The lytic cycle which is one of the cycles of viral reproduction is the cycle which leads to the breakup of the DNA of the cell ( i.e. destruction of the host cell and its membrane).
Therefore the yellow ring inside the bacterial cell will disappear by step 3 after which the nucleic acid is injected into the host cell by the virus .
Hence we can conclude that the bacterial DNA structure will disappear because of the usage of the ribosomes by the nucleic acid from the virus

100 POINTS! CORRECT ANSWER GETS BRAINLIEST! Study the image of chromosomes in a human cell. Do the chromosomes in this image belong to a female or a male? Autosomes and Sex Chromosomes You may have noticed in the image of chromosomes in a human cell that all of the chromosome sets are labeled with a number except one set, which is labeled with X and Y. Together, chromosome pairs 1 through 22 makes up your autosomes, which are chromosomes that contain genes for characteristics not directly related to the sex of an organism. Most sexually reproducing species also have sex chromosomes that directly control the development of sexual characteristics. Humans have two very different sex chromosomes: X and Y. In all mammals, including humans, an organism's sex is primarily determined by the XY system. An organism with two X chromosomes is female. An organism with one X and one Y chromosome is male.
