Cellular respiration and fermentation are metabolic pathways that transfer the energy in glucose to ______________________.
Cellular respiration and fermentation are metabolic pathways that transfer the energy in glucose to ATP.
Specifically, the energy held in glucose is converted to ATP during cellular respiration and fermentation. The chemical energy the cell can use is called ATP, or adenosine triphosphate.
What is the process of fermentation?
In the absence of oxygen, carbohydrates are broken down by the enzymes of microorganisms during fermentation. Because they possess distinctive sets of metabolic genes, microorganisms like bacteria and fungus are able to develop enzymes that can break down various kinds of sugar compounds.

The round body that sits inside the nucleus of a eukaryotic cell and makes ribosomal subunits from proteins and ribosomal rna is known as the.
Nucleolus is the round body that sits inside the nucleus of a eukaryotic cell and makes ribosomal subunits from proteins and ribosomal RNA.
What is ribosomal RNA?
Bi-somatic RNA Ribosomal ribonucleic acid (rRNA), which is the RNA component of the ribosome in molecular biology, is necessary for protein synthesis in all living things. It makes up the majority of the ribosome, which is made up of roughly 60% rRNA and 40% protein by weight.
The largest nuclear organelle, the nucleolus, is where ribosomal subunit biogenesis mostly occurs in eukaryotic cells. It forms specialized chromosomal structures called nucleolar organizing regions (NORs), which are the locations of ribosomal DNA transcription. These NORs are formed around arrays of ribosomal DNA genes.
Hence the correct answer is Nucleolus.

If you hold your finger next to the flame on a candle like the one in the picture, you can feel the heat, but you will not get burned; however, if you hold your finger above the candle, you will get burned. Why?
1.As the heated air rises, cooler air moves in to take its place. This causes convection and more hot air to to rise. Some thermal energy is radiated from the flane to the side of the candle, and that is why you feel the heat. It is hotter above the candle becasue of convection.
2.The shape of the candle flame directs the heat out through the top so if you place your hand at the top of the flame you could get burned
3.The sides of the candle are cooler than the flame so it doesn’t get as hot on the sides.
4.The candle absorbs the heat from the lower part of the flame so the top part of the flame is hotter.
Answer:
Pain
Explanation:
Because if you get burned by the flame is caused by your skin is not used to so much heat and if your skin get's too much heat it will burn and harm or even damage your skin internal and external organs so it is best not get into flames way and can also even cause death.

What can be used to determine the relative age of two rocks? question 13 options: vertical position the presence of unconformities radioactive dating of each layer relative age cannot be determined
The relative age of two rocks can be determined by: radioactive dating of each layer.
Radioactive dating is the method of determining the age of rocks or minerals using the radioactive substances. The method is very useful for determining the age of igneous and metamorphic rocks whose dating cannot be done using any other method.
Rocks are the solid aggregates of minerals, soil and many other components. According to their composition rocks can be of three types: Igneous, Sedimentary and Metamorphic. Igneous rocks are formed from molten rocks. Sedimentary rocks are formed by the layers of sand, silt and dead plants. Metamorphic rocks are formed from other rocks subjected to heat and pressure.

As a result, if a diploid zygote has 50 chromosomes, it signifies that the diploid organism as a whole has 50 chromosomes, which will be divided in half at the time of gamete creation during meiosis. Consequently, a gamete will have 25 chromosomes.
chromosomal number, the exact number of chromosomes that a certain species typically has. The number of chromosomes in any given asexually reproducing species is constant. The number of chromosomes in somatic (body) cells of sexually reproducing animals is normally diploid (2n; a pair of each chromosome), which is twice as many as the haploid (1n) amount found in the sex cells, or gametes. Meiosis is when the haploid number is formed. Some sexually reproducing creatures can generate individuals from unfertilized eggs, making them haploid; a drone is one example (a male bee).

Amendment is a formal and official change of some important document. Best- known are the amendments to the Constitution of the United States.
There is a formal procedure for passing the amendments.
Although the Third Amendment is rarely discussed in court, the First and Second Amendments receive a lot of attention. No soldier should be quartered in any residence during times of peace or during times of war other than in a way authorized by law, according to the complete text of the legislation.
In reaction to a particularly specific set of circumstances involving the British military in the late 18th century, the U.S. ratified it. Nevertheless, the modification has been discussed or taken into consideration by courts in a few 20th and 21st century judicial instances.
Tens of thousands of men were dispatched by the British Empire to its American colonies between 1754 and 1763 to fight in the French and Indian War for control of the Ohio River region. After then, many of these men remained in the 13 colonies as a standing army. The colonies were required to feed and shelter these soldiers under the Quartering Act, which was approved by the British Parliament in 1765.According to Gordon S. Wood, an emeritus professor of history at Brown University, "the colonists were to provide barracks for the soldiers, and if they were not available, the men were to be billeted in inns, stables, and alehouses."

How does prokaryotic and eukaryotic DNA replication differ?
The primary distinction between prokaryotic and eukaryotic DNA replication is that prokaryotic DNA replication occurs through a single replication origin, whereas eukaryotic DNA replication occurs through multiple replication origins.
There are three major types of polymerases found in prokaryotes: DNA pol I, DNA pol II, and DNA pol III. DNA pol III is now known to be the enzyme required for DNA synthesis, while DNA pol I and II are primarily required for repair. They are replicated by the action of telomerase, a unique enzyme that can keep telomeres alive by catalyzing their synthesis in the absence of a DNA template.

In a protein, the most conformationally restricted amino acid is Proline and the least conformationally restricted is Glycine.
The fact that proline's amino group is involved in bonding, resulting in imino (-NH-) rather than amino (-NH2), which is involved in the formation of a cyclic ring as a side chain, prevents it from being free to confirm. Proline is the most conformationally restricted amino acid due to the cyclic side chain's 60° phi value (angle between N and C').
Because it only has one hydrogen group (-H) in its side chain, glycine has the smallest conformational restriction of any amino acid. Because it is less sterically hindered, its presence in the Ramachandran plot is much greater than the permitted range.
