The scenario which describes a relationship of parasitism is a tick feeds on the blood of a dog. Therefore, the correct option is D.
What is parasitism?In parasitism, one organism (the parasite) benefits at the expense of another organism (the host). In this scenario, the tick benefits by feeding on the dog's blood, while the dog is harmed by the loss of blood and potential transmission of diseases by the tick.
Option A describes a mutualistic relationship, where the ox pecker birds benefit by feeding on the ticks, and the zebras benefit from having the ticks removed.
Option B describes a predator-prey relationship, where the polar bear benefits by catching and eating the seal, while the seal is harmed by being eaten. Option C and D describe commensalism. They both are same. Therefore, the correct option is D.

To see a general view of a microscope slide, use _____ power. If you need to see a more specific and detailed view, use _____ power.
Answer:
Low; high.
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Basically, a microscope is used for viewing very little objects, microorganisms and cells found in living organisms such as humans, animals and plants.
The interchangeable lenses found in a microscope which are close to the specimen being observed are called objective lenses. These objective lenses comprises of low power objective and high power objective. To see a general view of a microscope slide, use low power. If you need to see a more specific and detailed view, use high power.
Hence, the field of view (FOV) is largely dependent on the objective lens being used, it is largest (general view) for low power and smallest (specific and detailed view) for high power.

Why is it important that all amino acids share a common structure and only vary in their side group?
Answer:
The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. ... The polar and nonpolar chemical traits allow amino acids to point towards water (hydrophilic) or away from water (hydrophobic).

Summarize sexual reproduction in plants. I need help please!!
Answer:
Plant reproduction is the development of new offspring that can be achieved through sexual or asexual reproduction in plants. By the fusion of gametes, sexual reproduction creates embryos, resulting in offspring genetically distinct from the parent or parents. Asexual reproduction creates new individuals, genetically similar to the parent plants, without the fusion of gametes.

D. When the guard cells inflate with oxygen, they become stiff and

A. When the guard cells are full of water, they become stiff and hold
the pore open.
Two guard cells make up the stomata. The walls of these cells are thicker on the inside than they are on the outside. Stomata open when they take in water and close when they lose water due to the unequal thickness of the paired guard cells.When stomata open, they release water vapor and other gases into the atmosphere, including oxygen.A.

What role have nitrates and phosphates played in damaging Muddy Creek?
Answer:
Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.
Explanation:
Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.
Nitrates and phosphate found in water are usually from plants that have been washed off by rain water and also from vehicles' exhaust.
When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).
This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a swamp and eventually a meadow
Is The sun warms up the swimming pool conduction or radiation
Answer:
Given that water is clear and colorless, it seems that it will absorb very little direct radiation from the sun. The sides and the bottom of the pool can however heat it by conduction.
Explanation:
hope it help and if it doesnt sorry;)
Answer:radiation
Explanation:It’s radiation because when you conduct heat to something it mostly to an object and that is creating energy.Conduction is also mostly used with a object like wood doesn’t conduct heat well but metal does.
