Answer:
Ecosystem distribution
Explanation:
<u>The placement of biomes throughout the earth as a result of climatic factors such as temperature and precipitation is referred to as ecosystem distribution.</u>
Biomes generally represents a community of living organisms that are able to tolerate the climate of a place based on shared attributes. For example, all plants in the desert biomes are able to withstand low water.
An ecosystem refers a collection of different communities of organisms that are interacting with one another and their physical environment as a form of system.
Climatic factors such as temperature and precipitation delimits species distribution in an environment. Communities that are able to tolerate similar climatic conditions are placed in the same ecosystem. Hence, we have the <em>forest ecosystem, desert ecosystem, marine ecosystem, freshwater ecosystem, etc.</em>
Answer:
The majority of marine organisms are found in coastal regions.
Explanation:
The majority of marine organisms are found in coastal regions because ocean flows bring nutrient-rich water into coastal areas. Marine coasts are the type of environments that change through the weathering process and change in sea levels. Coastlines mostly consist of continental shelves that contain relatively shallow waters of having 200-meter depths only.
Since water is shallow here, photosynthetic processes are possible for marine life, which attracts more organisms to their primary food sources. Since the land is near shallow waters, discharges of nutrients from the soil are brought into the sea for the marine organisms so that they can use it. Aside from these reasons, cyclic upwellings in the sea also provide fresh and nutrient-rich waters for several species.
A protein coat, and some DNA or RNA that isn't normal for a typical human cell.
Answer:
True
Explanation:
Because of their chemical properties (hydrophobic lipid) these steroid hormones can pass through the plasma membrane and bind to their intracellular estrogen receptors in order to achieve their function ( modulate the expression of the genes).
Estrogen is the primary female sex hormone responsible for the development and regulation of the female reproductive system. It is also involved in the formation of secondary sex characteristics. Because of their roles, estrogenes are widely used as medications.
