Explanation:
what are the similarities between this activity and actual mitosis
The DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.
What is mitosis?Mitosis is defined as the cell-division process in which the chromosomes multiply and are equally distributed between the two daughter cells. Prophase, Prometaphase, Metaphase, Anaphase, and Telophase are the five stages that make up mitosis. Meiosis is defined as a process by which a single cell undergoes two divisions, resulting in four cells with half the original genetic material.
Cell division occurs during meiosis as well as mitosis. The M-phase of the cell cycle is where both processes take place. The prophase, metaphase, anaphase, and telophase stages are typical for both cycles. DNA synthesis occurs during both cycles. A common goal of meiosis and mitosis is the division of the nucleus and its DNA into two daughter cells.
Thus, the DNA within a cell is duplicated during both meiosis and mitosis. Two sister chromatids are produced for each chromosome as a result of the replication and continued joining of each DNA strand, or chromosome.

How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?
What is always true about the total amount of O2 and CO2 in the test tube?
What happens when the CO2 reaches zero?
Answer:
Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.
Explanation:
Without land regulations to protect rainforests, and continues to be destroyed using slash and burn methods Which environmental impact of rainforest deforestation makes rainforest species less resilient to
change?
Increased fire and drought
Increased pollution
Displaced inbes
Habitat fragmentation
Answer:
Increased pollution is your answer!
Explanation:
Increased pollution is your answer because:
1. ⇒ Burning of mostly anything creats, and all the materials in the forest are one of those materials that will create smoke. And smoke is made out of carbon dioxide, and other poisonous gases that are very bad for our atmosphere.
2. ⇒ The damage from the fire will also cause a lot of damage to the trees and plants. That is very bad because trees are very important for our environment, in their leaves, they have a chemical called chlorophyll, this chlorophyll absorbs sunlight and turns it into oxygen. Not only sunlight is needed, there is also, water, nutrients needed.

What is system of biological classification?The modern system of biological classification is the classification that involves the naming and arrangement of organisms in groups according to a hierarchical order.
In this type of classification, organisms are given scientific names based on their genus and the species.
This pattern of double naming is called binomial nomenclature consisting of two names.

Why do fossils that paleontologists find represent only a partial picture of life in the past?
Answer:
Because we cannot see some animals properly like jellyfish as their tissue is too soft, and feathers or for can often not make an imprint on fossils.
Explanation:
Answer:
Fossils: They are remains of animals or plants in the past that were somehow preserved and buried under the earth's crust.
One fossil can only give us a glimpse into the history of the time that particular animal or plant lived or breathed on the earth. For example, a fossil remains of a particular species of dinosaur would only provide information of the time when that species lived on earth and other information related to that particular time. Fossil remains of dinosaurs would not give us information on the time during the ice age or any other time in history.Explanation:
The study of various fossils can give us information about the development and evolution of living organisms over time but there are limitations to it.It may happen if we compare the fossil remains of an organism that existed billions of years ago we may find a time gap where there is no fossil evidence found so it creates a loop in information.Also, the process of fossilization is complex and long. Many species of the past became extinct without fossilization so we can never get information related to those extinct species.Thus, because of this reason we can say that fossils don't provide us with complete information about the past.For more information:
