The study of genes is called genetics.
The correct answer is A.
In the reproduction process, there are two parents involved in the process which leads to the mixing of two different types of a chromosome which have a different sequence of genes.
The mixing of the different genes leads to the formation of new characters by mixing the new genes and forming a new sequence.
The variation in the dogs is because of the variation in the gene sequence.
The genes are present on the chromosome and the chromosome is present inside the nucleus.
Hence, the correct answer is A that is a gene, chromosome, and nucleus.

About one hundred thousand years ago, very fluid lava started erupting slowly and gently from a place near a plate boundary. What best describes the slope of the mountain that resulted from such a phenomenon?
Steep slope with high mountain, as these are formed by a composite volcano
Gentle slope with mild hill, as these are formed by a composite volcano
Gentle slope with mild hill, as these are formed by a shield volcano
Steep slope with high mountain, as these are formed by a shield volcano
Answer:
Fluid lava (which is less viscous because it has less silica content) flows much further than viscous lava (that is high in silica content). Therefore, this types of lava forms shield volcanoes – low slopes and low height- because they flow over longer distances before they cool. Viscous lava from composite volcanoes that are high in height and have steep slopes.Explanation:

Why is the temperature of the liquid in the flask on the previous page measured when the liquid in the thermometer has stopped rising? Explain
How can the thermometer in the flask on the previous page be used to demonstrate the relationship between heat transfer and kinetic energy? Explain.
Answer:
when heated, the molecules of the liquid in the thermometer move faster, causing them to get a little further apart. this results in movement up the thermometer. when cooled, the molecules of the liquid in the thermometer move slower, causing them to get a little closer together.

Reproduction processes can produce offspring similar to and different from the parent
organisms. Which of the following would produce the most similar offspring?
F cutting a portion of a potato that contains an eye or bud and planting it in a
vegetable garden
G butterflies bringing pollen from one wildflower plant to another plant as they gather
nectar
H a scientist that cross-pollinates bean plants by transfer pollen from one flower to
another
J a bee collecting pollen from one flower to delivering it to other flowers within a
field.
Cutting a portion of a potato that contains an eye or bud and planting it in a vegetable garden would produce the most similar offspring due to vegetative propagation.
What is vegetative propagation?Potatoes are almost exclusively cultivated using vegetative means (cloning). Potato tubers each contain their own nodes or eyes, which are the origins of new growth. The new stalks that emerge from each eye are referred to as sprouts, and these are what give the young plant its start.
The offspring of plants that reproduce vegetatively are new plants that are genetically identical to their parents because they form from the vegetative components of their parents' plants. The progeny that are produced through vegetative reproduction are referred to as clones because of this.
Therefore, Cutting a portion of a potato that contains an eye or bud and planting it in a vegetable garden would produce the most similar offspring due to vegetative propagation.
