Answer:
La biogeografía es el estudio de la distribución de especies y ecosistemas en el espacio geográfico y a través del tiempo geológico.
Answer: The correct answer is-
B. by mutating their DNA in response to environmental conditions to gain beneficial traits.
Antibiotic resistance in bacteria means the bacteria is not susceptible to the antibiotic that is the effectiveness of antibiotic against the bacteria is eliminated or reduced.
It occurs when bacteria undergoes mutation that is alteration in the genetic material ( for instance, in one mechanism of resistance, mutation changes the protein that was earlier target for the antibiotic).
Therefore, by mutating the DNA in response to environmental condition ( such as exposure to antibiotic in this condition), bacteria gains beneficial characters and become resistant.
Thus, option B) is the right answer.
<h2>DNA and its evolution</h2>
Explanation:
- Evolution is how a species changes over many generations. A species is all the animals of one particular kind, like cats or turtles. Members of the same species can have babies with each other. A species evolves when parents pass down helpful traits to their children. A trait is anything about the animal. For example, some cats have long hair and some cats have short hair. When cats with long hair have babies, their babies also have long hair.
- Heredity alludes to the hereditary legacy went somewhere around our natural guardians. It's the reason we appear as though them! All the more explicitly, it is the transmission of characteristics starting with one age then onto the next.
- DNA stands for deoxyribonucleic acid. In eukaryotic organisms, such as animals, plants, and fungi, the DNA is stored inside the cell nucleus and in the chromosomes. Prokaryotes (bacteria) store their DNA only in the cytoplasm within their cells. This master molecule, the DNA, is the perfect hiding place for biological or genetic information.
- Any number of items, functions or purposes which are dependent upon each other function are interrelated to each other
- The purpose of evolution is known as the function
Answer:
last one
Explanation:
because they have no nucleus of any membrane bound organelles
Sudden stops in exercise are not good for the heart and blood vessels, therefore you might get Heart <span>Arrhythmias.
Not cooling down properly can also lead to blood pooling, which can cause dizziness.
