Answer:
C.
Explanation:
Before mitosis begins, which happens before the nucleus starts dividing?
The DNA replicates.
The cytoplasm separates.
The sister chromatids separate.
The homologous chromosomes cross over.
Answer:
The DNA replicates.
Before mitosis begins, the DNA replicates. During the S phase of interphase, which precedes mitosis, the DNA in the nucleus undergoes replication, resulting in the formation of identical sister chromatids.
This ensures that each daughter cell produced during mitosis receives a complete set of genetic information.
After DNA replication, the cell enters the mitotic phase, during which the nucleus divides and the replicated DNA is distributed to the daughter cells.
The cytoplasm separates during cytokinesis, which occurs after mitosis and is not directly related to events before nucleus division. The separation of sister chromatids occurs during anaphase of mitosis, not before the nucleus starts dividing.
Thus, the process of homologous chromosomes crossing over occurs during meiosis, not mitosis.

How can we learn about what the buffalo are eating? What kinds of data do we need?
The person can learn about the food habits of buffalo by observing the buffalo and its surrounding reduction in vegetation.
What is a Herbivore?These are the animals that can eat and digest only plant or plant-based material.For example- A buffalo can be observed to eat green grasses, small plants, leaves, etc. but buffalo cannot eat other animals or meat.This can be confirmed by the data of vegetation around a buffalo. Some animals eat other small animals or animal-based are known as carnivores.Therefore, the person can learn about the food habits of buffalo by observing the buffalo and its surrounding reduction in vegetation.

What might happen to the Burmese python population over time as it reaches or
surpasses its carrying capacity in South Florida? How might other organisms in the
ecosystem be affected? What might happen to the population sizes of various types
of organisms in the Everglades?
Answer:
If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.
Explanation:
If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.
What is carrying capacity?The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.
Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.

Answer: resource
Explanation:
A substance valued or required by any living organism(s) for survival is defined as a resource.
What is living organism ?The environment consist of both living and nonliving organisms with two interacting components such as Physical or abiotic and biological or biotic components.
The physical component are temperature, light, soil, air, and water where as the biological component are animals, plants, and microorganisms.
The biotic components are plants, animals, and micro-organisms while green leaves of the autotrophic plant have chlorophyll and this pigment help in making food using light, water, and carbon dioxide by the process of photosynthesis.
Animals on the other hand are heterotrophs need nutrients and absorb nutrients such as nitrogen, phosphorus, and calcium from the soil.
Decomposer and Scavengers feed on the dead bodies and decaying substances, animal release the nutrients trapped inside them.

Answer:
conclusion
Explanation:
hope this helps
Answer:
1. What caused the tree bark to become darker than it was, was the soot from factories in the Industrial Revolution.
2. The light-colored peppered moths have a higher rate of survival on the light bark since it's the same color as it and can't be easily spotted.
3. The dark-colored peppered moths have a higher rate of survival on the dark bark since it's the same color as it and can't be easily spotted.
4. What caused the population of light-colored peppered moths to decrease was the color of the tree bark. The tree bark was dark from the soot from factories. If the tree bark was a dark color, then light-colored peppered moths are more easily spotted, and since the tree bark is a dark color the dark-colored peppered moths can hide more easily, and not be as spotted than the light-colored peppered moths.
5. You have to answer this question. If the tree bark is a dark color, then the dark-colored moths have a better chance of surviving, but if the tree bark is a light color, then the light-colored moths have a better chance of surviving.

how does heat from the sun warm the earth?
Answer: the sun heats the earth through radiation
Explanation:
Answer:
Heat from the sun may warm the Earth when greenhouse gases absorb infrared radiation (IR), which you cannot see but can feel as heat. Dark surfaces also play a huge role in heating up Earth's surface, as they reflect less light and absorb most of the energy from the sun, in contrast to lighter surfaces, which reflect more light than it absorbs.
