Knowing that a model is considered a representation of something, the correct option is option B, in which the apple represents the Earth. An apple is sectioned into quarters to represent the ratio of water to land on Earth.

--------------------------------

To answer this question, you can think about a model as a representation of something.

A scientific model can represent an object, a system, a process, a phenomenon, etcetera.

Models are used to explain, predict, or describe natural events. They constitute a significant tool in modern science and are essential to scientific practice.

Knowing this, among the provided options, the one that is a model is option B.

The apple is representing the ratio of water to land on Earth. It is a representation of the earth.

All the other options are experiments performed to see what is going to be the result.

What is the process of photosyntheis step by step

dangina [55]

Answer:

Step 1

The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.

Step 2

Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.

Step 3

Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.

Step 4

The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.

Compare the three types of RNA. Note significant similarities and differences. Use the table below to record your observations.

Alchen [17]

Answer: (Structure) mRNA: always single stranded, rRNA: single stranded, twisted upon itself in some regions, tRNA: cloverleaf-like structure

(Function) mRNA: carries the information in the DNA to the ribosomes where it is translated into amino acids of proteins, rRNA: helps assemble tRNA, mRNA, and amino acids to form the polypeptide chain during protein synthesis, tRNA: acts as an adaptor molecule, which identifies correct amino acids corresponding to the anticodon present on it

Do you think scientists have an ethical obligation to speak out when a problem seems so severe

swat32

Yes, when a problem is severe or harmful, scientists are ethically and legally obliged to speak out.

Scientific experiments and testing are vital processes that lead to innovations, medicines, procedures, etc., that better human life. While scientific testing is required before a medicine, product or procedure can implemented or introduced in the market, it is essential to stop or prevent further testing when a severe problem or harm arises at the experimental stage.

For instance, if a clinical experiment testing the effects of a new hair loss prevention drug finds that consumption of said drug causes severe nausea and dehydration, scientists must speak out or stop the experiment to prevent further harm. A failure to prevent harm is both highly unethical and liable to legal consequences.

Differential media: 1. Allow the growth of fastidious microbes through the addition of certain growth enhancers 2. Support the g

Nookie1986 [14]

Answer: 3. Support the grouping of microbes based on different characteristics demonstrated in the media.

Explanation:

Differential media is the growth medium for the growth of bacterial culture. This media consists of specific ingredients that are necessary for distinguishing the selected species by visual examination. The differential media is used to distinguish between the closely related organism and differentiating them with other organisms.

Due to the addition of some dyes or chemicals that are specific to some of aids in observing the bacteria in the medium and their growth pattern can be identified. This kind of macroscopic differentiation of the bacteria shows the ability of the bacteria to conduct the biochemical processes.
