Answer:
The cells need water to maintain their metabolic functions, the way water enters through cells membranes is by osmosis.
Explanation:
The cell membrane is a lipidic bilayer composed of phospholipids and embedded proteins. Phospholipids have the characteristic of being amphiphilic which means that possess hydrophilic and lipophilic characteristics. The most common way is by osmosis, that is a mechanism that moves water from high concentration to less concentration of water. In the cell membrane, there are is channels of proteins called aquaporins that facilitate the pass of water through the membrane. Also, as water is a very small molecule without charge, this characteristic allows passing a limit amount of water molecules through the hydrophilic characteristic of membranes.
Coal came from swampy environments, while oil and natural gas came from open ocean environments is true about fossil fuels. The correct option among all the options that are given in the question is the third option or option "c". Coal mainly came from decomposition of plants for a long time and oils as well as natural gases are mostly found in ocean environments.
Since the
speed of many physiological processes in marine organisms is determined by the
temperature, the first consequence of the changes in the conditions of the
medium becomes offset the timing of seasonal events, such as the timing of
spawning fish. There have also offset migration routes and spawning areas. So,
as a result of warming in the Sea of Japan, spawning navaga shifted to an
earlier date, because of the reduction of the area of "cold spots"
in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab
are lengthened, but because of the temperature rise to the east of Japan,
spawning saury expanding. These changes significantly affect the success of
reproduction, resulting in changes populations of their fishery.
Answer:
13 is the answer for both
Explanation:
The atomic number is also the atoms count of protons and electrons when the element is of a neutral charge.
Answer:
Perception
Explanation:
Perception is usually defined as a collective process of accumulation, selection and interpretation, and organization of the sensory information. In simple words, it helps in the collection of information that is transferred from the different sense organs and interpreted by the brain. This collected information is used in understanding and interacting with the environment.
Thus, perception refers to the use of sense organs such as the nose, ear, eyes and making a person able to smell, hear and see things.
