Answer:
Yes
Explanation:
Yes, the impact on one species over time can impact ecosystem.
An ecosystem is consist of biotic and abiotic organisms. There is a major relationship between biotic and abiotic or biotic and biotic components.
The relationship between biotic and biotic components is called food chain, in which one organisms depends on others for their survival and balance the energy flow in the ecosystem. So impact on any one species in the food chain will impact the whole ecosystem.
For example: Plants are the producers in the food chain, and if plants will be impacted or destroyed over time, the consumers depending on the plants will die from starvation and disturb the energy flow in the ecosystem. Along with this, plants are also related to abiotic factors such as maintenance of oxygen and carbon dioxide in the atmosphere, so the balance of these gases will also get disturbed.
When voltage of a plasma membrane shifts from +30mV towards 0mV, we say cell is repolarizing. Repolarization results from the movement of positively charged K+ ions out of the cell. This repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting membrane potential.
Answer:
Explanation:
Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin.
Answer:
They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste,and the deep biosphere of the earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals. Most bacteria have not been characterised, and only about 27 percent of the bacterial phyla have species that can be grown in the laboratory.[5] The study of bacteria is known as bacteriology, a branch of microbiology.
viruse
A virus is a small infectious agent that replicates only inside the living cells of an organism. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.
