The five-carbon sugar in RNA is called
Answers
Answer:
Ribose sugar
Explanation:
This sugar is differentiated from deoxyribose sugar of DNA by the 2’ carbon of the carbon ring. This carbon in ribose has a hydroxyl group while that of deoxyribose sugar does not. When this ribose sugar is bonded with a nitrogenous base on the 1’ carbon and a phosphate on the 5' carbon, it becomes a ribonucleoside that is the basic unit of RNA.
The five-carbon sugar in RNA is called ribose. This sugar differs from the deoxyribose found in DNA by having a hydroxyl group on the 2' carbon. The ribose sugar, along with a nitrogenous base, contributes to the structure of RNA nucleotides which, unlike DNA, are single-stranded.
Explanation:The five-carbon sugar in RNA is called ribose. The ribose sugar in RNA differs from the deoxyribose sugar in DNA in that ribose contains a hydroxyl group on the 2' carbon. Furthermore, the carbon atoms of this sugar molecule in RNA are numbered as 1', 2', 3', 4', and 5' (with 1' being read as 'one prime').
The phosphate component of RNA connects to the 5' carbon of the sugar via the formation of an ester linkage. This linkage involves an ester, which is an acid + an alcohol composed of the phosphoric acid and the 5'-OH group. The 2' carbon of ribose also contains a hydroxyl group. Moreover, the nitrogenous base in a nucleotide is attached to the 1' carbon of the sugar.
Structure of Ribonucleotides in RNARNA nucleotides are essentially ribonucleotides, with ribose as the pentose sugar component and a nitrogenous base. These ribonucleotides form a single strand, with bases studded along the sugar-phosphate backbone. This single-stranded structure is what separates RNA from DNA, which typically exists as a double helix.

Ferns produce ATP during photosynthesis, while flatworms and people produce ATP during digestion.
Answers
Answer:
Ferns produce glucose that can be broken down by cellular respiration, while flatworms and people digest foods containing glucose for use in cellular respiration.
Explanation:
Ferns, humans & flatworms all require cellular respiration to live. This energy-productive process occurs in the cell cytoplasm and mitochondria. However, for cellular respiration to occur, it has to work on an energy-rich substrate. In cells, this substrate is usually glucose. Ferns are autotrophs hence can make glucose by photosynthesis because they have chlorophyll molecules. However, flatworm and humans are heterotrophs meaning they have to consume other organic compounds to get this glucose.

Each osteon consists of lamellae, layers of compact matrix surround a central canal (the haversian or osteonic canal) which contains the bone's blood vessels and the nerve Fibre. Osteon in compact bone tissue are aligned in the same direction along lines of stress, helping the bone resist bending or fracturing.
Hope it's helpful...
The layers of bony matrix surrounding the vessels and nerve are called lamellae which are part of the structure of osteons in compact bone. The bone is covered by periosteum membrane externally, and internally by the endosteum lining the medullary cavity.
Explanation:The term for the layers of bony matrix, or compact bone, that surround the vessels and nerve is called lamellae. Compact bone is organized into cylindrical structures known as osteons or Haversian systems. These osteons are composed of lamellae which are layered around a central canal, the Haversian canal. The Haversian canal contains the bone's blood vessels and nerve fibers. Osteocytes the cells of mature bone, occupy small cavities known as lacunae, found between the lamellae.
The outer surface of the bone is enveloped by a membrane known as the periosteum which contains blood vessels, nerves, and lymph vessels that nourish the compact bone. Tendons and ligaments are also attached to the bones at the periosteum. Within the bone the medullary cavity is lined with the endosteum where bone growth, repair, and remodeling occur.

A.) An air mass cannot transfer energy from one area to another
B.) A large mass of air takes on the temperature and humidity characteristics of the land or water under it
C.) And Air mass redistributes energy by moving from place to place
Answers
Answer:
A.) An air mass cannot transfer energy from one area to another
Explanation:
The air masses are constantly on the move. They can be warm and moist, or cold and dry, as well as hot and dry, all depending on the place above which they have formed. The air masses that form over warm, large bodies of water and warm and moist. The air masses that form over cold regions are cold and dry, and the air masses that form deeper into the continent in hot regions, are hot and dry. Because the air masses are constantly on the move, they manage to transfer their energy from one area to another, resulting in change of weather conditions as the energy is transferred.
The statement that an air mass cannot transfer energy from one area to another is not true. Air masses can and do transfer energy in ways such as conduction or radiation. The other choices accurately describe the properties of air masses.
Explanation:The following statement is not true of air masses: A.) An air mass cannot transfer energy from one area to another.
Air masses have the ability to transfer energy from one area to another in two ways: Via radiation or conduction. For instance, warm air masses can move and transfer heat to cooler areas, thus transferring energy.

Are a type of lipid that consists of fatty acids combined with alcohols or other
Answers
Final answer:
Lipids are a diverse group of organic molecules including triglycerides, which consist of glycerol bonded to three fatty acids. Triglycerides are the main component of body fat and can contain either saturated or unsaturated fatty acids. Other lipid types include phospholipids and steroids, all vital to organism function.
Explanation:
Lipids are a diverse group of organic compounds that are insoluble in water but soluble in organic solvents. They play vital roles in living organisms and include substances like fats, oils, waxes, and steroids. One common type of lipid is the triglyceride, which is formed when a glycerol molecule combines with three fatty acid molecules. Glycerol is a sugar alcohol, a simple, sweet-tasting, non-toxic compound that is colorless and odorless.
Triglycerides are the primary constituent of body fat in humans and animals, and can also be found in plant-derived fats. They are important for storing energy and providing insulation. Triglycerides come in many varieties but can be broadly categorized into two types based on the fatty acids they contain: those with saturated fatty acids and those with unsaturated fatty acids. The unsaturated ones are commonly found in plant products and are associated with health benefits.
Other types of lipids include phospholipids and steroids, each of which has unique functions in the body. Phospholipids are essential components of cell membranes, while steroids, like cholesterol, serve as precursors to important hormones and have structural roles in cells.

Answers
Answer:
Microtubules
Explanation:
These filament-like structures are a major component of the cytoskeleton of the cell and help is maintain asymmetrical cell shape. They are composed of tubulin molecules arranged to form a 'hollow straw' attached to the cell membrane end to end . The contraction and lengthening of these microtubules are controlled by the addition of removal these of tubulin molecules to vary its length.
In the case of elongated, tube-shaped cells from the lining of the intestine sagging and becoming rounded after treatment with a certain chemical, the internal structures likely disrupted are the microtubules. These structures are part of the cell's cytoskeleton and help maintain its shape, particularly in the case of columnar epithelial cells.
Explanation:When elongated, tube-shaped cells from the lining of the intestine are treated with a certain chemical, the cells sag and become rounded. The internal structures disrupted by this chemical are probably microtubules.
Microtubules are part of the cytoskeleton of a cell, helping to maintain its shape and also serving crucial roles in intracellular transport and cell division. If they are disrupted, the cell can lose its form, leading to a rounded shape. The elongated, tube-shaped cells in the lining of the intestine, also known as columnar epithelial cells, have a stack of microtubules that maintain their elongated shape. Thus, a chemical treatment that disrupts the microtubules would cause the cells to lose their elongated form and become rounded.

Two genes coding for proteins involved in glycolysis reside on the same chromosome. Can these genes assort independently?
Answers
Answer:
Yes
Explanation:
The Gene's can assort independently
When the two genes coding for different proteins involved in glycolysis reside on the same chromosome, then these genes can assort independently if they are located far apart from each other on the chromosome.
What is Linkage and independent assortment?
Linkage occurs in a chromosome when two or more genes are linked together and are always inherited together in the same combination for more than two consecutive generations, whereas in case of recombination the genetic material of an organism is exchanged between different organisms which ultimately leads to the production of offspring with the combination of traits.
Mendel's Law of Independent Assortment states that during a dihybrid cross, an assortment of each of the pair of traits is independent of the other pair of traits. In other words, during gamete formation, one pair of trait or gene segregates from the another pair of traits or genes independently.

Identify the phrase that best describes a transfer of energy between the hydrosphere and the atmosphere.
1)Ocean currents transport warm water from the equator to the poles and cold water from the poles to the tropics.
2)These currents help regulate air temperatures and, therefore, the global climate, counteracting the uneven distribution of solar radiation reaching Earth.
3)If there were no currents, the temperature near the equator would be extremely hot, and the temperature near the poles would be extremely cold.
4)These areas would not be suitable for living things to survive.
Answers
Answer:
2) These currents help regulate air temperatures and, therefore, the global climate, counteracting the uneven distribution of solar radiation reaching Earth
Explanation:
The ocean currents are part of the hydrosphere. They receive warmth from the sunlight. They warm up at the lower latitudes, and cool off at the higher latitudes. The ocean currents are in constant movement though, and they warm up the higher latitudes, and cool down the lower latitudes. The warming up and cooling off of the temperatures goes through the radiation of energy from the ocean currents. That radiation goes to the air masses, thus there is a transfer of energy from the hydrosphere tot he atmosphere. This transfer of energy between these two spheres helps to balance and modify the climate around the globe.
The phrase that best describes a transfer of energy between the hydrosphere and the atmosphere is:
1) Ocean currents transport warm water from the equator to the poles and cold water from the poles to the tropics.
Option 1) "Ocean currents transport warm water from the equator to the poles and cold water from the poles to the tropics." best describes a transfer of energy between the hydrosphere and the atmosphere. Ocean currents play a crucial role in redistributing heat energy around the globe. Warm currents carry heat from the equator towards the poles, while cold currents transport cold water from the poles towards the tropics. This movement of water helps regulate air temperatures, influencing the climate on both regional and global scales. By transferring heat energy between the hydrosphere and the atmosphere, ocean currents play a significant role in shaping weather patterns and maintaining the Earth's overall climate balance.

Meiosis involves cell divisions.
Answers
Answer:
Meiosis involves two cell divisions
Explanation:
Mitosis and meiosis are two kinds of cell divisions and one of the main differences between the two is that meiosis goes through 2 nuclear divisions.
Meiosis has Meiosis I and Meiosis II division. In Meiosis I, the number of chromosomes in the daughter cells are only half of the parent cells. This is why it is called a reduction division, because the chromosomes will be reduced by half. In Meiosis II, the daughter cells will have the same number of chromosomes as the parent cells, which in this case is the daughter cells of meiosis I.

Answer:
C. Prokaryotic poly-A tails have other functions, because prokaryotes don't have nuclei.
Explanation:
In eukaryotes, the poly-A tails help in import of mRNA from cytosol to nucleus with the help of proteins named as importins and then export of mRNA from nucleus to cytosol with the help of proteins named as exportins. In prokaryotes they serve the function of mRNA degradation instead. In prokaryotes, mRNA doesn't need to be imported and exported because they do not have a well defined double membranous organelle named as nucleus. All of their genetic material lies in the cytosol in the form of nucleoid.
In eukaryotes, poly-A tails serve many other functions apart from export and import like it imparts stability to mRNA, facilitates degradation of mRNA and increases translation efficiency by helping in circularization.
