Describe how Stella’s view of these cells and their parts changed as she transitioned through the three levels of magnification. Be sure to identify at least one cell structure or part of the paramecium in your description.
Answers
Answer:
The paramecium body.
Explanation:
1. The objective lenses on a compound light microscope doess have powers that start of as smallest to highest power, 4x, 10x, and 40x on the maximum power setting. This means that the sample can be magnified either, 40x, 100x or 400x.
At 40x magnification Stella will see organism 5mm.
At 100x magnification Stella will be able to see organism 2mm.
At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.
2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.
Pellicle capacities like skin and shields them from the components. For movement they have cilia.
Answer:
At 40x, Stella could see the cells, but they looked really small. At 100x, Stella was able to see the cells to the point where she could see most of them up close. At 400x, Stella could see the cells one by one close enough. Some of the cells are shoe-shaped, which is one of the characteristics of paramecium. The brown at 400x next to the orange is the one that mostly looks like a shoe.

Which of the following is an example of reproductive isolation? two populations of finches that cannot produce viable offspring two populations of finches that have different feather colors two populations of salamanders that live in different lakes two populations of salamanders that have different tail lengths
Answers
The correct answer is A. Two populations of finches that cannot produce viable offspring
Explanation:
Reproductive isolation is a biological and evolutionary phenomenon that prevents two species from successfully reproducing, this means they cannot produce offspring or the offspring is not fertile, even if these species had a common ancestor. Additionally, as a result of reproductive isolation, each species keeps its genes and features. This phenomenon is best exemplified in "Two populations of finches that cannot produce viable offspring " because this refer to the barriers for different species to reproduce or produce viable offspring, which is the focus of reproductive isolation.

Where is the energy shown in the equation transferred as a result of photosynthesis?
into water
into the air
into sugars
into the ground
Answers
Answer:
The chemical equation of Photosynthesis in the question is not clear but the energy goes into water.
The answer is "Into Water"
Explanation:
Photosynthesis is a metabolic reaction which involves the synthesis of sugars (Glucose) in plants using carbondioxide and water input in the presence of sunlight. Photosynthesis, which occurs in the Chloroplast of plant cells, occurs in two stages viz: light dependent stage and light-independent stage.
The light dependent stage involves the production of ATP and NADPH molecules, which will be used in the light-independent stage. The chemical equation of photosynthesis is as follows:
6CO2 + 6H2O ---light energy--> C6H12O6 + 6O2
The light energy input in this reaction (from sunlight) is used in the light-dependent stage to break down water molecules, a process called PHOTOLYSIS OF WATER. The photolysis of water releases electrons and protons used to build a proton pump for the synthesis of ATP.
Therefore, the energy input from photosynthetic process goes into water.

Which specialized carbohydrate is used in shrimp exoskeletons?
Answers
Answer:
A specialized carbohydrate that is used for structure in shrimp is called chitin. Not only it is found in the shrimp cells, but also on other crustaceans such as crabs and lobsters. Chitin is a derivative of glucose and a characteristic element in the exoskeletons of crustaceans, cell walls of fungi, internal shells of squids and octopuses, and scales of fish.
Explanation:
The specialized carbohydrate that is used in shrimp exoskeletons is chitin.
An exoskeleton refers to an external skeleton that protects and supports the body of an animal. The specialized carbohydrate that is used in shrimp exoskeletons is chitin.
Chitin is a fibrous substance that's made up of polysaccharides. It's the major constituent in the exoskeleton of arthropods. Chitin can also be found in crustaceans. It is a derivative of glucose.

Answers
Answer:
1st term- groundwater discharge
2nd term- subsurface runoff
3rd term- surface runoff
4th term- groundwater runoff
Explanation:
I hope this helps:)
Surface runoff: falling rainwater that flows over the ground.
Subsurface runoff: the water that infiltrates in the vadose zone; an example is falling rainwater that gets absorbed into the soil
Groundwater runoff: describes water pulled by gravity across land's surface, replenishing groundwater and surface water as it percolates into an aquifer.
Groundwater discharge: this describes the movement of groundwater from the subsurface to the surface i.e. groundwater returns back to land.
How do you explain surface runoff?Runoff is nothing more than water "running off" the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
What is a runoff in groundwater?Runoff is the water that is pulled by gravity across land's surface, replenishing groundwater and surface water as it percolates into an aquifer or moves into a river, stream, or watershed.

Anaerobic respiration in yeast.
Anaerobic respiration is economically important - many of our foods are produced by microorganisms respiring anaerobically. Yeast is used to making alcoholic drinks. When yeast cells are reproducing rapidly during beer or wine production, the oxygen is used up.
How do humans benefit from the products of anaerobic respiration?Another advantage of anaerobic respiration is its speed. It produces ATP very quickly. For example, it lets your muscles get the energy they need for short bursts of intense activity (see figure below). Aerobic respiration, on the other hand, produces ATP more slowly.

What could happen if a person doesn’t get the proper amount of protein in his or her diet? The impact of a diet lacking in protein would be of little consequence. Stored proteins would assist in creating new amino acids that the body needs. The body would break down existing muscle to get the amino acids it needs.
Answers
Answer:
The body would break down existing muscle to get the amino acids it needs.
Explanation:
If a person doesn’t get the proper amount of protein in his or her diet, then the body would break down existing muscle to get the amino acids it needs, which are present in the last option.
What is the function of proteins?Proteins are made up of building blocks called amino acids; some of these amino acids can be produced by the body, while others must be obtained through the diet, so if a person does not consume enough dietary protein, their body may not have access to enough essential amino acids to build and repair tissues or produce enzymes. As a result, the body may break down muscle tissue in order to obtain the amino acids it requires, resulting in muscle wasting; the immune system may not function optimally; and so on.
Hence, the body would break down existing muscle to get the amino acids it needs, which are present in the last option.
