Answer:
reduction in biodiversity by eliminating spawning and nursery grounds of aquatic life
Explanation:
Estuaries are transition zones localized between rivers and marine ecotones. These regions are influenced by marine factors such as waves, tides, and saline water, while rivers provide freshwater and sedimentary material. The mixture between seawater and freshwater is generally highly nutritive, thereby estuaries often represent high-production systems where fishes and shellfishes spawn and grow. However, many estuaries have suffered the negative effects of human activities, including deforestation, drainage, overfishing, nutrient pollution, etc.
Cell membrane: Scattered in the lipid bilayer are cholesterol molecules, which help to keep the membrane fluid consistent. Membrane proteins are important for transporting substances across the cell membrane. They can also function as enzymes or receptors. On the extracellular fluid side of a cell membrane, you find carbohydrates.
Cytoplasm: Function of Cytoplasm. The jelly-like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts.
Nucleus: Function of the Nucleus. The nucleus is an organelle found in eukaryotic cells. Inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
Cell wall: The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.
Answer:
mixing chemicals together
Explanation:
eating and drinking
An epoch is longer than an era.
Answer:
The acidic environment in the stomach stops the action of the amylase enzyme.
The stomach will secrete digestive juice that contain hydrochloric acid and digestive enzyme such as pepsin to digest protein.
The HCL create an acidic environment that will deform the ionic and hydrogen bond of the amylase which cause the enzyme to be denatured.
