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.

How does ground water relate to lakes or rivers?
All lakes and rivers are replenished by groundwater.
When ground water reaches the surface it can form lakes or rivers.
Groundwater can affect the size of lakes and rivers.
Lakes and rivers produce groundwater.
Answer:
When ground water reaches the surface it can form lakes or rivers.
Explanation:
Groundwater in valleys is often pushed under pressure by rainwater that falls on the nearby highlands. If the water table reaches the surface, a lake, a river, or a spring is formed. A spring in desert country is surrounded by plants that take advantage of the water supply, forming an oasis. Water now coming to the surface at oases in the Sahara Desert came from rain that fell on hills near the desert during the Middle Ages--eight hundred to one thousand years ago.

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.

Explain the characteristics you observed when studying the epithelial types of the Epithelial Tissue from Kidney and Epithelial Tissue from Dermis and Epidermis images.
Answer: The epithelial tissue is a membranous tissue which has a function of covering.
Explanation:
The cuboidal epithelial tissues are present in the proximal convoluted tubules or PCT these tissues help in absorption of materials present in the filtrate generated in the glomerulus. These includes necessary salts, glucose, amino acids, water, gets selectively reabsorbed.
The stratified squamous epithelium are present in dermal layer of the skin. The dermal layer is the layer which receives the nerve supply of blood and nourishment. The epithelium helps in secretion of sweat and protection against microorganisms.

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.

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.
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.

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.
