acid rain is made by sulphuric acid which is toxic for human and water and land species.
when acid rain reaches the pond, the acid will mix with H20. the biodiversity will likely become mutant.
Answer:
B i hope this help
Explanation:
The cell membrane consists primarily of a thin layer of phospholipids which spontaneously arrange so that the hydrophobic "tail" regions are shielded from the surrounding polar fluid, causing the more hydrophilic "head" regions to associate with the cytosolic and extracellular faces of the resulting bilayer. This forms a continuous, spherical lipid bilayer approximately 7 nm thick, barely discernible with a transmission electron microscope.
The arrangement of hydrophilic and hydrophobic heads of the lipid bilayer prevent polar solutes (e.g. amino acids, nucleic acids, carbohydrates, proteins, and ions) from diffusing across the membrane, but generally allows for the passive diffusion of hydrophobic molecules. This affords the cell the ability to control the movement of these substances via transmembrane protein complexes such as pores and gates.
Vacuoles store the materials needed for the cell.
Answer:
C. is a passive process caused by increased intrathoracic pressure.
Explanation:
Inhalation is an active process as it includes the contraction of muscles and diaphragm. Exhalation is a passive stage of breathing. It does not include any muscular contraction. Rather, diaphragm and the external intercostal muscles become relaxed. This reduces the volume of the thoracic cavity and lungs. The reduced volume causes increased air pressure in alveoli as compared to the atmospheric pressure. The increased pulmonary pressure drives the movement of air towards the outside of the body.
Answer:
The correct answer is - Trains can have inconvenient schedules, but produce less pollution than cars do.
Explanation:
Trains are expensive to build and also required land for making routes and stations and platforms for passengers but that can be reimbursed by fare in a longer time period.
Trains also produce pollution but in comparison to cars these are way less contribute to the pollution, However, these are not convenient as they start and reach at a specific time and also sometimes not comfortable like cars.
