Which combination of alleles are always involved in the inheritance of a se.x-linked trait?
heterozygous alleles
hom.ozygous alleles
alleles that are carried on X and Y chromosomes
alleles that are carried on all chromosomes except the X and Y chromosomes
For the se.x-linked traits, the aleles are carried on X and Y chromosomes in organisms.
What are alleles?Alleles refers to a pair of genes that control the same trait but are expressed in different ways. The combinantion of alleles in an organism determines the phenotype.
The inheritance of a se.x-linked trait is linked to alleles that are carried mostly on the X and Y chromosomes in organisms.

According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.
Explanation:
Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.
In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.
Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.
In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.
The other options are not correct because:
Cell growth occurs in G1 phase.Cell preparation occurs in interphase.DNA replication occurs in S phase.Mitosis is represented in yellow, and involves 4 phases.Epithelial cell must be replaced quickly in order to prevent _______________________ and ____________________ from entering.

Answer: Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
Explanation:
what is cell cycle and what are its main phases?
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Answer:
Water vapor
Explanation:
Water vapor is the gaseous phase of water. Combustion of 1 cubic meter of fuel in a solid fuel furnace produces 0.8 liters of water vapor.
It can be produced by the evaporation of boiling water or the sublimation of ice. Water vapor is water in gaseous instead of liquid form. The water when it's boiling it doesn't disappear, it becomes gas, ,
What,generally, is the current level of deforestation in the United States? In developing nations? How would you expect the deforestation in developing nations to change in the next 100 years? Explain.
The current level of deforestation is increased. This is due to the fact that the industrial revolution has taken its place, and wood is one of the main reasons for deforestation.
What is deforestation?The large-scale removal of trees from forests (or other places) to make way for human activity is known as deforestation.The deliberate clearance of forested terrain is known as deforestation.
Forests have been cleared throughout history and into the present era to make room for agriculture and animal grazing as well as to obtain wood for fuel, manufacture, and construction. Around the world, deforestation has significantly changed the terrain.
Therefore, the rate of deforestation is rising at the moment. This is because the industrial revolution has replaced it, and wood is now one of the primary causes of deforestation.

In anaerobic respiration , one molecule of glucose is broken down into two molecules
Answer:
In anaerobic respiration , one molecule of glucose is broken down into two molecules of pyruvate which are then converted to lactate
Explanation:
Cellular respiration is the process by which cells metabolize glucose through various steps and pathways to produce energy in the form of ATP molecules. Cellular respiration is of two types: aerobic and anaerobic respiration. Oxygen is present in aerobic respiration to accept the electrons produced in glycolysis whereas it is absent in anaerobic respiration.
In anaerobic respiration, glucose is broken down in ten reaction steps into two molecules of pyruvate. Two net ATP molecules are also released.
The overall equation for glycolysis is: glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O
The two pyruvate molecules produced are then converted to lactate when they accept electrons from NADH molecules. The equation is given below:
2 pyruvate + 2NADH ⟶ 2 Lactate + 2 NAD+

how can an understanding of the interactions between matter and energy help you understand whether different carbon reservoirs are growing or shrinking?
Answer:
Carbon reservoirs are shrinking.
Explanation:
the interactions between matter and energy help us to understand and provides information whether different carbon reservoirs are growing or shrinking because when the matter converts into energy, it releases heat energy along with different gases. For example, when volcanic eruption occurs the carbondioxide gas is released in this process which shows that carbon reservoirs are shrinking.
Answer:
By understanding the amount of energy devoted to processes that release carbon versus processes that store it, one can gain an understanding of how the carbon concentrations in different reservoirs are changing.
why does moving pollen from one pollen to another help the plants
Answer:
Flowers have male parts called stamens that produce a sticky powder called pollen. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants. The plants must be of the same species.

Do you think scientists will succeed in being able to make objects totally invisible?
Answer:
Yes I do
Explanation:
Scientists already made a shield that could make you sort of invisible
Answer: I don't think so
Explanation: To be honest, being able to be invisible either has to do with the time of day and what your wearing. Take for example, robbers wear all black when robbing at night. When they run, It'll be almost impossible to make them out in the night unless you shine a light on them.
