Answer:
3.
Explanation:
A classroom desktop is the least likely to grow bacteria because it is a relatively clean surface. The armpit of a human and a warm freshwater mud puddle are a more suitable habitat for bacteria because they are warm, and provide a relatively safe environment for them
The study of the environment is called ecology.
The correct answer to the question is C which is a classroom desktop.
What is bacteria?Bacteria are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometers in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitatsAccording to the question, A classroom desktop is the least likely to grow bacteria because it is a relatively clean surface.
The armpit of a human and a warm freshwater mud puddle is a more suitable habitat for bacteria because they are warm, and provide a relatively safe environment for them
Hence, the correct answer is option 3.

Is glucose more or less complex than the rest of the biomolecules? Explain.
Answer:
Less complex.
Explanation:
Glucose is both a monomer and simple sugar.
Glucose is a monosaccharide. It is a biomolecule. It is less complex than the rest of the biomolecules, such as proteins, lipids, and other complex carbohydrates like glycogen.
What is a biomolecule?
Biomolecules are present inside the cell. Carbohydrates, proteins, and lipids are some examples of biomolecules. Carbohydrates are divided into monosaccharides, disaccharides, and polysaccharides.
A monosaccharide has a single unit. Examples are glucose, fructose, etc. A disaccharide consists of two units. An example is maltose. Maltose is made up of two units of glucose connected by a glycosidic bond. An example of a polysaccharide is glycogen. Multiple sugar units are connected by glycosidic bonds to form glycogen. It is a storage product.
Carbohydrates are present on our cell surface as peptidoglycan. Protein is a biomolecule that is made up of amino acid monomers. They make the different structures of a cell, such as actin fibers, etc. Lipid is made up of hydrogen and carbon. Examples are cholesterol, phospholipids, etc.
Hence, in comparison to all other biomolecules, glucose is the simplest.

How might volcanic eruptions change the flow of energy on earth?
Answer:
It causes global warming due to emission of carbondioxide gas.
Explanation:
Volcanic eruptions change the flow of energy on earth by emitting gases such as carbondioxide and sulfur dioxide gases. Volcanic gases like sulfur dioxide is responsible for global cooling by reflecting solar radiation back to the space, while on the other hand, carbon dioxide emitted from volcanoes, has the ability to promote global warming by blocking solar radiation. If the amount of carbondioxide gas is higher as compared to sulfur dioxide gas so global warming occurs.

(d) State the importance of mitosis in the growth of a multicellular organism, such
as a
flowering plant or a mammal.
Explanation:
Like other multicellular organisms, plants grow through a combination of cell growth and cell division. Cell growth increases cell size, while cell division (mitosis) increases the number of cells. As plant cells grow, they also become specialized into different cell types through cellular differentiation.

List and explain the 3 paths natural selection can take.
Answer:
1. Stabilizing Selection
2. Directional Selection
3. Disruptive Selection
Explanation:
Stabilizing Selection
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed:
Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
Directional Selection
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side:
Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
Disruptive Selection
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such:
Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

A helpful shortcut our brain makes in scene recognition is to assume that lighting comes from:
Answer: A. Above
Explanation:
Scientists believe that in order for humans to see things, the brain has to make certain assumptions which are done based on previous scenes that it has interpreted before because the eyes do not provide it with complete data. .
One of those assumptions is that light comes from above which is why the shape of a picture can change depending on the lighting in it.
