what trait only appears when a organism is a homzygous
Answer:
Both can show.
Explanation:
The genotype can look like the following:
TT <= Homzygous Dominant
tt <= Homzyogous Recessive
Tt <= Heterzygous
See? It would be hard to determine exactly which trait would show without the second half of the name! (By the way, I can't say the proper names so I apologize)
I hope this helps! ^-^

What process is represented in the picture above?
The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. View Available Hint(s) The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid always requires energy when _____. a transport protein is involved in the movement of the molecules the lipid bilayer is permeable to the solute the concentration of the solute is lower inside the cell than outside it the concentration of the solute is higher inside the cell than outside it
Answer:
the concentration of the solute is lower inside the cell than outside it
Explanation:
This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.
This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.

he bodies of wild-type fruit flies are colored by dark pigments, but an X-linked recessive mutation can confer a yellow, unpigmented phenotype. However, feeding silver salts to larvae results in adult flies that phenocopy the yellow phenotype. You are conducting epistasis experiments in fruit flies to understand the genetics of pigmentation. A rival research lab sends you a vial of yellow-bodied flies for your experiments. How can you tell whether these flies are mutants instead of phenocopies
Answer:
We could feed them with another type of food free of silver salts.
Explanation:
When talking about a phenocopy, we are referring to individuals who genotypically should be expressing a determined phenotype, but due to environmental influence, they express another phenotype. This is a non-inheritable phenotype, so it is not considered a mutation.
If we grow thy flies feeding them another type of food that does not include silver salts, and let them mate and reproduce, they will express the real phenotype, because they will not be influenced by the food. In the following generation, there will be dark individuals carrying the dominant allele, and yellow individuals, with the recessive genotype.
Why do rats have three lobes of liver and humans only have one?
Answer:
Although the rat liver is typically lobated2 and its ap- pearance does not resemble that of the human liver, the hepatic lobes of the rat liver have been found to be equivalent to the sectors of the human liver. As rats and humans belong to the class Mammalia, similar em- bryological development is expected.

The International Astronomical Union (IAU) defines a constellation by its:
boundary
star pattern
brightest star
Greek name
Answer:
Each constellation is a region of the sky, bordered by arcs of right ascension and declination. ... Together they cover the entire celestial sphere, with their boundaries adopted officially by the International Astronomical Union in 1928 and published in 1930.
So I would say its A : Boundary
Explanation:
- Eijiro <3
Love the pfp by the way! :D
The International Astronomical Union (IAU) defines a constellation by its boundary. The correct option is A.
What is International Astronomical Union?In 1919, the International Astronomical Union (IAU) was established. Its goal is to encourage and protect astronomy in all of its forms, including research, interaction, education, and development, through international cooperation.
The International Astronomical Union (IAU) is the oldest intergovernmental organization of professional astronomers, having been in existence for over a century. It has over 13000 members and 82 national members, among them India.
The IAU designates a constellation by its boundary rather than its pattern, and the same constellation can have multiple representations. Asterisms should be distinguished from constellations.
Thus, the correct option is A.

How do both sodium and potassium ions travel
Answer:
Sodium ions pass through channels in the hydrophobic barrier that have been formed by membrane proteins. The crossing membrane is called facilitated diffusion because it is facilitated by the channel
Potassium ions have to be transocated through specific membrane transport proteins. It is then transported into the cell through potassium pumps with energy being consumed int the form of ATP.
The sodium-potassium pump goes through cycles of shape changes to help maintain a negative membrane potential. In each cycle, three sodium ions exit the cell, while two potassium ions enter the cell. These ions travel against the concentration gradient, so this process requires ATP.
Explanation:
Answer:
The sodium potassium pump goes through cycles of shape changes . In this way they help maintain a negative membrane potential. In each cycle, two potassium ions enter the cell while three sodium ions exit the cell . These ions travel against the concentration gradient. And this process requires ATP.

Explanation:
certain minerals form only under high heat and oressure that develop near volcano. That is why minerals vary among areas.
The option (C) is correct. Certain minerals form only in specific climates, and not all climates, are the same around the world.
What are minerals?A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.
Moreover, the major minerals, which are used and stored in large quantities in the body, are calcium, chloride, magnesium, phosphorus, potassium, sodium, and sulfur. The trace minerals are just as vital to our health as the major minerals, but we don't need large amounts.
Therefore, economic minerals are used in a wide range of applications related to construction, manufacturing, agriculture and energy supply. Economic minerals include: Energy minerals used to produce electricity, fuel for transportation, heating for homes and offices and in the manufacture of plastics.
