Marco has experienced extreme fatigue (tiredness) lately. He eats three balanced meals each day and exercises 2-3 times per week on his Peloton bike. He gets 7-8 hours of sleep each night, but just can’t seem to stay awake during the day. Which organelle is most likely causing Marco’s problems?
Answers
Given the symptoms shown by Marcos, we can infer that the organelle that may be causing his problems is the mitochondria.
The mitochondria are one of the most famous and important organelle within a cell. Found in most eukaryotic cells, they are the organelle responsible for most of the energy production of a cell, and throughout the cells of the body, they become responsible for the energy production of the organism. This is the origin of its famous "Powerhouse of the cell" title. Mitochondria produce energy in the form of ATP.
ATP is a molecular compound necessary for most of the reactions that take place in a cell. It is so common as a requirement for any cellular activity that ATP is known as the "molecular currency". Marcos is said to be experiencing chronic fatigue, which is a symptom of mitochondrial disease. When the mitochondria of an organism's cells are not functioning as they should be, the cells do not have the energy needed to perform basic functions.
In reaction to this, the body sends signals to the brain to go to sleep, which minimizes energy consumption by slowing down the metabolic processes which require ATP and thus gives the body time to produce more energy. For these reasons, we can conclude that the fatigue and problems Marcos is experiencing are due to mitochondrial disease.

Which of the following does not describe a source of greenhouse gases?
Steam of fossil fuels
Burning of fossil fuels
Freezing of permafrost
Emissions from landfills
Answers
Answer:
i think its C) Freezing of perma frost
Explanation:
The option that does not describe a source of greenhouse gases is the freezing of glaciers. Thus, the correct option is C.
What are greenhouse gases?Greenhouse gases may be defined as those gases that are present in the earth's atmosphere and trap the heat and radiation from the sun and emitted toward the earth.
Such greenhouse gases are responsible for the greenhouse effect that ultimately leads to global warming.
Steaming and burning of fossil fuels and emissions from landfills extremely liberated the high amount of carbon dioxide in the atmosphere which is one of the most potent greenhouse gas.
Therefore, the option that does not describe a source of greenhouse gases is the freezing of glaciers (hailstone). Thus, the correct option is C.

Answers
Answer: The correct answer is A. nucleic acids.
Explanation: The genetic information is stored in the form of nucleic acids i.e. deoxyribonucleic acids (DNA) or ribonucleic acids (RNA).
Nucleic acids are large macromolecules in cells and viruses. Nucleic acids store and express genetic data. Therefore, option (A) is correct.
What are nucleic acids?The biopolymers and macromolecules known as nucleic acids are fundamental to every known type of living being. Nucleotides, which are the monomers that make up nucleotides, are composed of a 5-carbon sugar, a phosphate group, and a nitrogenous base. They are the building blocks that make up nucleotides. Deoxyribonucleic acid and ribonucleic acid are the two primary subgroups that can be found among nucleic acids.
Nucleic acids, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), are responsible for carrying genetic information. This information is read in cells and used to produce RNA and proteins, which are necessary for the functioning of living things.

Discuss the unique properties of water. (Polar, Hydrogen bonds, Cohesion, Adhesion)
Answers
Answer:
Water has cohesive and adhesive properties.
Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.
Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. ... Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.
Answer & Explanation:
The difference in electronegativity between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms.
Water molecules attract or are attracted to other polar molecules.
Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.
Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size. Water is also a good solvent for ionic compounds and many others because it readily forms hydrogen bonds with the solute.
Cohesion holds hydrogen bonds together to create surface tension on water.
Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.
Water is transported in plants through both cohesive and adhesive forces; these forces pull water and the dissolved minerals from the roots to the leaves and other parts of the plant.
Key Terms:
hydrogen bonds: A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
adhesion: The ability of a substance to stick to an unlike substance; attraction between unlike molecules
cohesion: Various intermolecular forces that hold solids and liquids together; attraction between like molecules
hydrophilic: having an affinity for water; able to absorb, or be wetted by water
hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water
polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.
