Answer:
A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Answer:
Tilling breaks the natural structure of the ground by exposing the organic matter, accelerates mineralization, and pollutes.
Explanation:
Organic matter, together with porosity and humidity directly influence in the recovery of the soil structure and stability when these are exposed to different mechanical treatments or actions. Porosity and soil matrix continuity directly influence in the hydraulic conductivity and interchange water and air processes.
Tilling systems affect the productivity of the crops, and the physic, chemical and hydraulic characteristics of the soil. Tilling modifies the superficial layer of soil, alters the continuity of porosity and reduces the amount of organic matter in the ground.
Intensive use of tilling contributes severely to the carbon emission. Carbon is stored in the soil and when this last one is altered by tilling, carbon is exposed and released out in the open, becoming CO². This gas is one of the gases of the greenhouse effect and one of the causes of global warming.
Intense tilling breaks the natural structure of the ground by exposes the organic matter, it accelerates mineralization, and it pollutes.
Answer:
A sample of a specific species of microorganism was added to 100 mL of a liquid culture medium. ... The 1 mL of experimental culture medium was replaced by 1 mL of new sterile culture medium to maintain a constant volume.
Answer:
b) glycolisis
Explanation:
Glycolisis precedes the Krebs cycle and can take place under aerobic or anaerobic conditions. Under aerobic condition, energy is directed towards the Krebs cycle in the form of piruvate and NADH to create more ATP. Under anaerobic conditions piruvate does not enter the Krebs cycle and it is oxidized to produce lactate.
