DNA is transferred from one bacterium to another. After the donor cell pulls itself close to the recipient using a structure called a pilus, DNA is transferred between cells. In most cases, this DNA is in the form of a plasmid. An F+ donor cell contains its chromosomal DNA and an F plasmid
Answer:
Red blood cells and the heart causes response to stimuli
Answer:
c) allowing an organism to adjust to changes in environmental conditions
Explanation:
A stimulus can be defined as any change in the external or internal environment that produces a corresponding response in the organism. These responses enable the organism to maintain an internal equilibrium (homeostasis). Gene expression in prokaryotes, which are the simplest forms of life, is highly regulated by environmental stimuli. Some examples of stimuli known to regulate gene expression patterns in prokaryotic organisms are light, water, pressure, temperature, etc.
Answer:
All the answers are correct
Explanation:
An inhibitor of carbonic anhydrase would interfere with oxygen binding to hemoglobin, increase blood pH due to increased H+, increase the amount of bicarbonate formed in the blood and decrease the amount of carbon dioxide dissolved in plasma.
Carbonic anhydrase catalyses the reaction between carbon dioxide and water to form carbonic acid. Carbonic acid dissociates to form hydrogen carbonate ions and hydrogen ions. The hydrogen ions combine with haemoglobin to form weak haemoglobinic acid.
