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.
No, not always. If there are more recessive traits in a human, then it will show recessive. However, There are more people in a population with Dominant genes over recessive ones.
Answer: About 97 percent of Earth's water is in the ocean.
Answer:
carbon dioxide from living beings is also returned to the atmosphere through processes of respiration of dead tissue.
The answer is (c) respiration
Burning fossil fuels or cement has relatively little of an influence on humans in terms of producing carbon dioxide. The general people has been duped into believing we are a major factor in the greenhouse effect.
The biggest misconception regarding the movement for people to emit no net amount of CO2 is that natural supplies of this plant nourishment dwarf our emissions. This indicates that even if all people disappeared overnight, atmospheric CO2 levels would not significantly drop.
The statistics on the steady increase in CO2 throughout the heaviest periods of the global lockdown, which significantly restricted any human-sourced emissions, will give you a decent idea of this.
As for the so-called greenhouse gases, CO2 naturally occurs in water vapor, which makes up more than three times as much of the GHG as CO2. This indicates that the human component of the GHG is 0.6 percent.
When you take into account how little human emissions are in the grand scheme of things, you have to stop and wonder if any efforts you make to lower your emissions are in vain.
