Explanation:
Describe limits to cell division.
Answer:
All cells in the body have this internal control and most cells only divide between 50-70 times before they stop or die.
The study of cells is called cell biology.
The cell theory is given by Rudolf Virchow
The postulates of a cell theory are as follows:-
All the organism is made up of cellThe structure and the functional unit of life is the cell.All the pre-existing cell is made up of old cell.The limits of the cell division are cancer cells. The cancer cell does not stop after a limit. It divides continuously and forms a tumor.
Hence, the correct answer is a cancer cell.

Answer:
The nucleus is like the principal of a school, the cell membrane is like a school building, and the mitochondria is like the staff in a school.
Explanation:
Definitions:
The nucleus of a cell contains the majority of the cell's genetic material, and coordinates cell activities like protein synthesis and cell division.The cell membrane is the semipermeable membrane of a cell that surrounds the cytoplasm (the material inside the cell other than the nucleus).The mitochondria is "the powerhouse of the cell", because it produces most of the chemical energy needed to power the cell's chemical reactions.The nucleus is like the principal of a school: the nucleus controls the cell, much like how the principal controls the school.
The cell membrane is like a school building: the cell membrane forms a boundary between the cell and outside environment, much like how the school building separates you from outside.
The mitochondria is like the staff in a school: the mitochondria powers the cell, much like how the staff in a school keep the school running.

how do mutations and natural selection lead to resistant populations of bacteria
Answer:
Mutations are one way for bacteria to become resistant to antibiotics. Some spontaneous mutations (or genes that have been acquired from other bacteria through horizontal gene transfer) may make the bacterium resistant to an antibiotic (See: Resistance mechanisms for information about how bacteria resist antibiotic action). If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.

How are the processes of the water cycle essential to an unpolluted biosphere?
Answer:
Explanation:
if things on earth like dead animals or polluted chemicals in the air can affect the biosphere so keeping the stages of the water cycle safe and clean are essential to keeping the biosphere unpolluted. because Evaporation & transpiration distill water naturally, it filters out minerals and pollutants.

Calculate the force needed to cause a 6 kg bowling ball to accelerate 20 m/s2.
Answer:
Explanation:
F = m * a
m = 6 kg
a = 20 m/s^2
F = 6 * 20
F = 120 N which is short for Newtons.
If a cell in G1 has 20 chromosomes, then at the end of meiosis I there will be _________ chromosomes in each daughter cell, and __________ sister chromatids in each daughter cell.
Answer:
10 chromosomes
20 chromatids
Explanation:
Meiosis is the process by which sexually reproducing organisms produce gametes for sexual reproduction. Meiosis, which reduces the chromosomal number of the parent cell by half, occurs in two stages namely: meiosis I and meiosis II.
Meiosis I is where the actual reduction in chromosomal number takes place because homologous chromosomes are separated in this stage. For example, a cell in G1 that has 20 chromosomes will have 10 chromosomes in each daughter cell at the end of meiosis I.
Since, DNA replication occurs in the S-phase, sister chromatids are formed for each chromosome. Hence, there would be 20 sister chromatids joined together by a centromere at the end of meiosis I.

A biologist from another galaxy might think that automobiles are a dominant form of life on planet Earth. Automobiles move, consume gasoline and oil, and produce wastes. They are sheltered in garages and respond to stimuli. Automobiles age and break down, but new automobiles appear every year. They evolve, changing in appearance from year to year.
What arguments would you use to persuade the alien visitor that cars are not alive?
Answer:
Organisms need 6 things to be considered living which are, responsiveness to the environment, the ability to reproduce, having a metabolism, being able to breathe, maintaining homeostasis, being able to pass down traits, and made of cells. Cars, do not have the ability to reproduce, do not maintain homeostasis, cannot pass down traits, do not have a metabolism, etc... a living being needs to fit all of the criteria to be considered living. In this case, cars do not fit the criteria.
Knowing this, you would tell the alien about the 6 things needed to be considered a living being. After that, you would tell the criteria that the car does not fit which would then explain how a car is in fact, not a living being.

Try reducing the level of fossil fuel percentage increase and decrease deforestation by 1 GT per year. Predict what will happen to the atmospheric carbon levels and record it in your Data Table. Run the simulation to test your hypothesis. Were you correct? Were you surprised by the result? What about your result surprised you?
Answer: The atmosphere can handle almost 700 billion tons of carbon in it. The carbon levels are increasing due to industrial revolution.
Explanation:
The overload of the emission of carbon in the atmosphere surprised me. The data was recorded and investigated for 2000 to 2100. Different parameters like ocean water and fossil fuel. The fossil fuel when burn contribute to the release of carbon monoxide and carbon dioxide gas. The oceanic water release the decomposed carbon dioxide by calcium carbonate of coral reefs and respiration of aquatic animals.

Why do you think ANIMAL CELLS are able to survive without the types of cell walls that are present in nearly every other group of organisms? Provide 3 answers.
Answer:
They survive because these cells need a high permeability to be able to maintain the internal cellular balance in relation to the external environment that surrounds them, and this is due to their high energy demand, their multi-complex and multiple functions, and the capacity for constant homeostasis with the environment. that surrounds them.
Explanation:
In addition, some cells need to transmit signals, second messengers or even to fulfill a function to exchange compounds for their transmembrane, this is what makes the human system together with other systems of other animals is extremely open and is in constant energetic exchange, in addition to Unlike plant cells, plant cells are under an autonomous regime, they do not need to take energy from the environment but they manufacture it themselves, and it fulfills a great function that is to provide structure and support, the wall they have is what gives it the ability to fulfill these two functions.
