red-green colorblindeness occurs more commonly in men than it does in women. using this information, which chromosome do you suppose the gene for red-green colorblindness resides on, and is the trait dominant or recessive?
Answer:
Usually the Y chromosome. It is recessive because if one Y chromosone is mutated with red-green colorblindness and the X is not, the child will have colorblindness. But, if one X chromosome has the mutation and the other X does not, they will cancel out, meaning the child will not have colorblindness.
How do the properties of water and the ability to modify the rates of chemical reactions enable living things to carry out functions necessary for life, such as digesting food?
Answer:
A chemical reaction is a process that changes some chemical substances into others. It involves breaking and reforming chemical bonds. They follow the Law of Conservation of Matter.
Explanation:
Energy is a necessity for all living organisms to survive, and ATP is a reactant that powers several other chemical processes inside cells. Cellular respiration is the method used by cells to produce energy.
What attributes of water are requisite for an organism?The term “universal solvent” refers to water's enormous capacity to dissolve a wide range of molecules, and it is this capacity that makes water such a priceless life-sustaining agent.
Water has five key characteristics: strong polarity, high specific heat, high heat of vaporization, low solid density, and affinity for other polar molecules.
The process of converting one chemical substance into another is known as a chemical reaction. Chemical bonds are broken and rebuilt in this process. The Law of Conservation of Matter is observed by them.
Therefore, Water's function as a solvent aids cells in the transfer and utilization of chemicals like oxygen and nutrients on a biological level.

Which of the following is an accurate description of a positive feedback loop? SC.912.E.7.7
A.
It is uncommon in nature and it makes systems stable.
B.
It is common in nature and it doesn’t change the stability of systems
C.
It is uncommon in nature and is usually caused by humans
D.
It is common in nature and it makes systems stable
Regulatory functions such as feedback loops are very common in nature and happen thousands of times every day within our bodies alone.
A feedback loop is one of the methods by which biological organisms regulate functions. Feedback loops are a self-regulatory means through which the output of a system is then used as the input. Feedback loops can be of two types:
Positive FeedbackNegative FeedbackA positive feedback loop is one in which the system is stimulated to increase the production of a product. For example, the low levels of an enzyme in the blood will cause the body to produce more of that enzyme in a positive feedback loop. A negative feedback loop is just the opposite, in which high levels will cause a decrease in production.
Feedback loops are a vital part of maintaining homeostasis and for the survival of all organisms. Therefore, we can conclude that option D is correct in stating that feedback loops are common in nature and make the system stable.

Answer:
B) Oxygen and E) Carbon Dioxide
Explanation:
Cellular respiration has a general chemical equation as:
[tex]C_6H_{12} O__6[/tex] [tex]+6O_2[/tex] ⇒ [tex]6CO_2[/tex] [tex]+6H_2O[/tex]
glucose + oxygen ⇒ carbon dioxide + water
Photosynthesis has a general chemical equation as:
[tex]6CO_2[/tex] [tex]+6H_2O[/tex] ⇒ [tex]C_6H_{12} O_6[/tex] [tex]+ 6O_2[/tex]
carbon dioxide + water ⇒ glucose + oxygen
Reactants are on the left side of the equation while products are on the right. You can see that the products in cellular respiration are carbon dioxide and water, these also are the reactants in photosynthesis. So (B) Oxygen and (E) Carbon dioxide are the answers.

what is a chain of molecules linked with peptide bonds
Answer:
polypeptide chain
Explanation:
each amino acid unit in a polypeptide is called a residue. A polypeptide chain has polarity because its ends are different, with an α-amino group at one end and an α-carboxyl group at the other.
A chain of molecules connected by peptide bonds forms a polypeptide, a fundamental component of proteins. Peptide bonds are chemical bonds that link amino acids, the building blocks of proteins. This chain structure determines a protein's shape and function.
A polypeptide is made up of a series of molecules connected by peptide bonds and is an essential component of proteins. The coupling of amino acids is made easier by peptide bonds, which are produced by a condensation reaction between the carboxyl group of one amino acid and the amino group of another.
These amino acids, which are the building blocks of proteins, each have a distinct side chain, or R-group, which influences their characteristics. A polypeptide chain's amino acid composition determines the protein's three-dimensional shape, which is essential to its function. This complex link between structure and function emphasizes the importance of peptide bonds in biological processes.

Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.
What is protein?
Proteins are among the most prevalent organic molecules in biological systems and have a much wider range of structural and functional variations. Many thousands of proteins, each serving a different purpose, can be found in a single cell.
All proteins are composed of one or more chains of amino acids, despite the fact that their structures and activities differ substantially from one another.
In biological reactions, enzymes function as catalysts, accelerating the reactions. Each enzyme may distinguish between one or more substrates, or the molecules that act as the catalysts for the reactions they catalyze.
Therefore, Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.

What drives surface currents?
differences in air temperature
differences in climate
differences in water density
differences in water salinity
Answer:
WHAT DRIVES SURFACE CURRENTS?
Surface currents in the ocean are driven by global wind systems that are fueled by energy from the sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
DIFFERENCES IN AIR TEMPERATURE.
Movement of air due to differences in temperature between two locations is known as convection or advection. Convection is the term commonly applied to vertical movement of air, whilst advection is used in the context of horizontal displacement of air.
DIFFERENCES IN CLIMATE.
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
DIFFERENCES IN WATER DENSITY.
High temperature makes water less dense. As water gets warmer, its molecules spread out, so it becomes less dense. As it gets colder, it becomes denser. Most chemicals get denser when they turn from a liquid to a solid, but water is different.
DIFFERENCES IN WATER SALINITY.
As we have seen, most differences in salinity are due to variations in evaporation, precipitation, runoff, and ice cover. All of these process occur at the ocean surface, not at depth, so the most pronounced differences in salinity should be found in surface waters.
