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.

In the Bird Beak Gizmo, how did the bird beak depth change in drought conditions?
O No change
O Beaks got shorter beacuse the birds had to scrape more to find seeds.
Beaks got longer because the only birds that survived had larger beaks that could crack the hard seeds
Answer:
I think it would be #3, Beaks got longer because the only birds that survived had larger beaks that could crack the hard seeds
Explanation:
In years of extreme drought, the small, delicate seeds get eaten up quickly, leaving behind only the largest, toughest seeds.

Collagen has: Group of answer choices pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable). rings of glycine, which can stabilize helices and proline residues at every third position (because only proline residues can fit inside of the super-helical cable). rings of proline and glycine residues at every second position. pyrrolidine rings, which can push off and destabilize the helix and glycine residues at every second position (because only glycine residues can fit inside of the super-helical cable).
Collagen has: A. pyrrolidine rings, which stabilize helices and glycine residues at every third position (because only glycine residues can fit inside of the super-helical cable).
Collagen can be defined as the main or most abundant structural protein found in the bones, tendons, connective tissues, skin and muscles of a living organism such as a human being.
Basically, collagen is a chemical substance (protein) made up of amino-acids and it holds the human body together.
Hence, collagen typically makes up about 30% of the proteins contained within the human body.
Additionally, collagen comprises the following specific amino-acids:
Hydroxyproline.Glycine.Arginine.Proline.Each of the three chains of a collagen triple helix with 3.3 residues per turn, is normally stabilized by the steric repulsion between the pyrrolidine rings of hydroxyproline, glycine and proline residues.
Therefore, the pyrrolidine rings of collagen helps in the stabilization of helices and glycine residues, at every third position because the only residue that fits inside of the super-helical cable is the glycine residues.

the tensor fascia latae is involved in hip __________.
Answer:
Abductor Muscle.
Explanation:
The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).

What is the name of a species that is the first species to colonize an
area?
Select one:
a. Frontier species
b. Pioneer species
c. Explorer species
d. Pilgrim species
Answer:The answer is b. Pioneer species
Step-by-step explanation; The first species to colonize an area after a major disturbance are called pioneer species; they help to form the new environment. Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow.

during which stage of meiosis does the diploid parent cell become four separate haploid cells?
Answer:
To summarize, meiosis is a cellular process in which a diploid parent cell divides into four haploid daughter cells. One very important event in meiosis is crossing over, which occurs between prophase and metaphase I. Crossing over increases genetic variation. The haploid cells produced through meiosis are otherwise known as gametes.

an energy drink advertises that it contains atp. will this atp be absorbed by your muscle cells, thereby increasing the amount of atp within your muscles?
Yes, the ATP will be absorbed by your muscle cells and increase the amount of ATP within your muscles.
What is ATP?ATP is adenine triphosphate, which is an organic compound.
The role of ATP is to provide energy to carry out many functions of the living cells.
The ATP is made up of one adenine atom attached to nine carbon atoms and one sugar group.
The ATP is the energy source and if we drink, an energy drink, the ATP will go to the body.
Thus, the given statement is true.

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.
