Select the most complete model that shows the cellular structures present in all living cells.
Answer animal cells
Explanation:
The most complete model that shows the cellular structures present in all living cells is option B. So, the correct option is (B).
What is Animal Cell?An animal cell is defined as the type of eukaryotic cell that lacks a cell wall and has a true, membrane-bound nucleus as with other unicellular organisms.
Animal cells are generally smaller than plant cells. Animal cells are irregular in shape due to the absence of a cell wall. But animal cells share other cellular organelles with plant cells as both evolved from eukaryotic cells.
Animal cells consist of following cell organelles:
Cell membraneNucleusNuclear membraneCentrosomeLysosomeCytoplasmGolgi ApparatusMitochondriaRibosomeEndoplasmic reticulumVacuoleNucleoporeThus, the most complete model that shows the cellular structures present in all living cells is option B. So, the correct option is (B).

differentiate between the structure and function of the following plant cell organelles cell membrane, cell wall, nucleus, cytoplasm, mitochondria, chloroplasts, and vacuole
Answer:can you break it down for me
Explanation:it needs to be explained to me first for me to understand
The cell wall is only found in plants, whereas the cell membrane is found in all living organisms, including plants. Only found in plants and a few fungi, bacteria, and algae. Introduce in all types of cells, including humans, animals, plants, and bacteria.
What is a cell?In biology, the base unit that can live by itself and is made up of all living organisms and body tissues.
Photosynthesis occurs in chloroplasts; cell walls allow plants to be strong and upright; and vacuoles help regulate how cells handle water and other molecules.
Mitochondria provide metabolites for epigenetic modifications and other nuclear-associated activities, and mitochondrial proteins have been discovered in the nucleus.
The material or protoplasm within a living cell, excluding the nucleus, is referred to as cytoplasm.
Whereas the nucleus is a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
Thus, these are the basic differences between plant cell organelles cell membrane, cell wall, nucleus, cytoplasm, mitochondria, chloroplasts, and vacuole.

List two types of chemical erosion
Answer:Oxidation and Hydrolysis
Answer:
The most vivid examples of chemical erosion are caves and sinkholes created in areas with a lot of underground limestone that ends up dissolving from acidic groundwater.
Explanation:
Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts. Oxidation - the breakdown of rock by oxygen and water, often giving iron-rich rocks a rusty-coloured weathered surface.

A. A renewable resource is more likely to run out.
B. A renewable resource can never be replenished.
C. A renewable resource has a higher demand
D. A renewable re purse is replenished faster than it is used
Answer:
Explanation:
d
A renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.
What is a Renewable resource?A renewable resource may be defined as a type of resource that significantly continues to exist in nature despite being consumed or can replenish itself over a period of time even as they are utilized by the organisms.
Examples of renewable resources may include wind power, solar energy, geothermal energy, biomass, etc. These resources are available in nature in unlimited amounts as compared to non-renewable resources.
Therefore, a renewable resource is different from a nonrenewable one by the fact that a renewable resource is replenished faster than it is used. Thus, the correct option for this question is D.

Calculate the number of liters of liquid that are in Lake Erie, which has a volume of 484 cubic km (km3). Express your answer in scientific notation.
Answer: The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]
Explanation:
The conversion factor is : [tex]1km^3=10^{12}L[/tex]
Given : Volume of liquid in Lake Erie = [tex]484km^3[/tex]
To find : Volume of liquid in Lake Erie in units of liters
As [tex]1km^3=10^{12}L[/tex]
Thus [tex]484km^3=\frac{10^{12}}{1}\times 484=484\times 10^{12}L[/tex]
The answer in scientific notation is [tex]4.84\times 10^{14}[/tex]

. What causes a hurricane to form
will give brainliest to smartest answer
Answer:
For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm. As it rises, the air in a hurricane rotates.
Explanation:
In short pressure zones over warm ocean
Answer:
When warm moist air over the water rises, it is replaced by cooler air.
The cooler air will then warm and start to rise.
If there is enough warm water, the cycle will continue and the storm clouds and wind speeds will grow causing a hurricane to form.

When Mendel crossed hybrid pea plants, he observed that certain traits would appear in the next generation more often than others. He also observed that traits did not show up in offspring in predictable combinations. For example, not all tall plants had green peas, while not all short plants had yellow peas. Which term describes this observation?
A. Dominance
B. Sex Linkage
C. Segregation
D. Independent Assortment
The law of independent assortment describes that it is not necessary for the plant to have only the predictable observations. New combinations of characters can also develop in plants. Thus, the correct option is D.
What is Independent Assortment?Mendel in his laws of genetics described that there are two different alleles present for all the characters in an organism where, one allele is dominant and the other is recessive.
The principle of Mendel's law of independent assortment describes how the different genes separate from each other independently when the reproductive cells develop in an organism. Independent assortment of genes and their corresponding traits were observed for the first time by Gregor Mendel in 1865 during his studies of genetics in the garden pea plants (pisum sativum).
Therefore, the correct option is D.

Identify how Newton's third law of motion was responsible for the astronaut's return to the space station.
Answer:
sorry i cant understand clearly
Explanation:
i hope its help more
Answer: The equipment will "push back" on the astronaut with the same amount of force.
Explanation: Newton's third law of motion can be summed up as "For every action, there is an equal and opposite reaction." This means that when the astronaut applies force to push the object, that object will apply an equal amount of force to the astronaut.
