In order to be considered wet, the fish should be introduced to the air first as having to be wet is where you are introduced to a water in a state that you're not in or on. The fish submerged in the water is not considered wet as this is its natural habitat.
Answer:
All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4) ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.
Explanation:
In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid
Answer:
Increased fossil fuel use has increased atmospheric carbon dioxide.
Explanation:
Burning fossil fuels increases the amount of CO₂ in air, which is unhealthy.
Answer: B
Explanation:
Seasons on Earth occur due to tilt of its axis. Earth's axis is tilted 23.5° from the vertical. As the Earth revolves around Sun, the hemisphere is points towards Sun experiences summer season and the hemisphere points away from the Sun experiences winter.
It is given that U.S. is experiencing winters. U.S. lies in the northern hemisphere. Thus, the image which depicts winters in U.S. is image B as the sun rays are falling directly in southern hemisphere and northern hemisphere is pointing away from the Sun.
The correct answer is prey predator relationship.
The given graph possibly shows the prey predator relationship, in which the prey is shown in red and the predator is shown in blue. It is observed that the predator population generally remain less than the prey, in order to get food easily.
The prey predator relationship shows that if the population of the prey start increasing, then the population of the predator would also increase, as the predators have abundant of food. But when the population of the prey start decreasing, the predators start to decline due to the starvation.
