<span>Proteins that minimize fluctuations in pH are known as buffers. A buffering agent can be either a weak acid or weak base. Buffering agents are usually added to water to form a buffer solution, which only slightly changes its pH in response to other acids and bases being combined with it, particularly a strong acid or a strong base.</span>
Answer:
Mutation.
Explanation:
Mutation may be defined as the sudden heritable change in the DNA sequence of the organisms. Mutation can results in the change in the genotype and phenotype of the organisms.
Two main types of mutation are spontaneous mutation and induced mutation. Induced mutation occurs intentionally with the help of the mutagens. Spontaneous mutation is the natural mutation that occurs for the no known reason.
Thus, the answer is spontaneous mutation.
The three ways in which drugs affect the synapses include; they affect the number of neurotransmitters available, the rate of release of neurotransmitters, and binding affinity of neurotransmitter receptors to the neurotransmitters. For example; Drugs can affect the production of neurotransmitters, movement of neurotransmitters into vesicles, or movement of vesicles to a synapse.
Answer:
Asexual and Sexual reproduction.
Explanation:
Reproduction can either have one or two parents. Based on this there is two types of reproduction:
Asexual: A type of reproduction where a single parent is divided by itself and reproduce its offspring.
Sexual: A process where two parents participate in producing their offspring.
Answer:
Parasitism
Explanation:
Batrachochytrium dendrobatidis is a parasitic chytrid fungus which is responsible for the declining population of amphibians in the rain forests of Panama and Australia.
The fungus grows on the keratinized layer of epidermis on amphibian skin and makes a thick covering of fungus on the amphibian's skin. So as amphibian's skin helps them to maintain the proper osmotic balance in the body so when a thick fungus grows on their skin they are not able to maintain the correct osmotic balance in their body which leads to amphibian death.
So as Batrachochytrium dendrobatidis is a parasitic fungus and gets its nutrition from the frog body and do not kill frog immediately as in predation therefore this relationship can be considered as parasitism.
