when are chromosomes (dna) copied?​

Answers

Answer 1

Answer:

Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids.

Have a good day. :)

Answer 2

Answer:

Chromosome replication

Explanation:

Chromosome replication is a key event during the cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome and distinguish these sister chromosomes from one another.

why do planets take different times to comple an orbit?​

Answers

If a planet is close to the Sun, the distance it orbits around the Sun is fairly short. This distance is called an orbital path. The closer a planet travels to the Sun, the more the Sun's gravity can pull on the planet. The stronger the pull of the Sun's gravity, the faster the planet orbits.

What is an exothermic reaction?

When a chemical reaction takes place, energy is transferred to or from the surrounding in the universe. When the energy is transferred to the surrounding, there is a loss of energy, this reaction is called an exothermic reaction, and the temperature of the surrounding increases during this reaction.

The process of dissolving a substance is exothermic when more energy is released when water molecules bond to the solute particles in the solution than is used to break the solute particles apart. Because, more energy is released than is used in this process, the molecules which are present in the solution move faster, and thus results in an overall increase in temperature.

Therefore, the correct option is C.

If you have a hamster with long fur, what possible genotypes could the hamster have?

Answers

Answer:

Ll, Ll, LL

Explanation:

So, there is one thing we must remember to answer this:

1# dominant genes(long fur) are expressed over reccesive genes(short fur)

Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. Long fur - Ll, lL

Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. Long fur - LL

Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll

How does a fire help grasslands?

Choose all that apply

Answers

Answer:

In most grassland ecosystems, fire is the primary mode of decomposition

Explanation:

Grasslands burn more readily than forest and shrub ecosystems, with the fire moving through the stems and leaves of herbaceous plants and only lightly heating the underlying soil, even in cases of high intensity. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. In some grassland systems, fire only became the primary mode of decomposition after the disappearance of large migratory herds of browsing or grazing megafauna driven by predator pressure. In the absence of functional communities of large migratory herds of herbivorous megafauna and attendant predators, overuse of fire to maintain grassland ecosystems may lead to excessive oxidation, loss of carbon, and desertification in susceptible climates. Some grassland ecosystems respond poorly to fire.

A fire helps grasslands through the following:

Keeps trees from overtaking the grasses.Preserve biodiversity.

What is Fire?

This is the visible aspect of combustion of fuel and other materials to produce heat and flame.

what type of destruction result in primary succession

Answers

Answer:

Destruction that ends with the creation of new land, like a volcanic eruption

Explanation:

Primary succession refers to how life comes to be in a new land that has never been inhabited before. So any type of destruction that creates land that has never supported life would cause primary succession. Volcanic eruptions is the most common type of destruction for primary succession because the lava cools and becomes new land. Primary succession is defined by succession occurring in an area that does not have any soil for life to grow on.
