Explanation:
Antibiotic resistance happens when germs like bacteria and fungi develop the ability to defeat the drugs designed to kill them. That means the germs are not killed and continue to grow. Infections caused by antibiotic-resistant germs are difficult, and sometimes impossible, to treat.
hope this helps you.
Ans.
The Che proteins (chemotaxis proteins) are cytoplasmic proteins that play an important role in signal transduction pathways between the repellent or attractant and flagellar motor switch of a bacterium. Bacterial cell membranes contain different chemoreceptors for different attractants and repellents.
When a repellent or attractant binds with a chemoreceptor, stimulation of signal-transduction pathway occurs. It sends a signal to the cytoplasmic domain of receptor, which interacts with Che proteins, present at cytoplasm. The rate of auto-phosphorylation decreases when an attractant binds with receptor, while the rate of auto-phosphorylation increases when an attractant binds with receptor.
Thus, 'the attractant enhances smooth swimming and counterclockwise rotation towards the chemical source, which repellent enhances tumbling clockwise rotation away from a chemical source.'
It is true that Urban sprawl covers land once used for food
production and destroys ecosystems. Many of the large cities that have come up
were once fertile lands for irrigation or were big jungles. These jungles were
cut down or the fertile lands destroyed to build cities and industries.
By the United States Census Bureau standards, a population
of 1000 people define an urban area is completely false statement. As per the
United States Census Bureau, more than 50000 people define an urban area.
Answer:
The <u>genotype </u>is the internal hereditary code that tells which <u>phenotype</u> will be expressed.
Answer:
i think it would be A for wild fire, D for flood and E for Tsunami
Explanation: wild fire are one of the most common ways for a secondary succession that can bring change when the environment is disturbed or damaged. For instance, by allowing fast-growing plants to grow and provide a source of food and shelter for many animals to use and eventually draw them back into the ecosystem. Both flooding and tsunamis help push older organisms and other stuff from the environment to create for room for other plants and animals to come and keep the ecosystem healthy and ongoing.
