Answer:
A: Unlike DNA, XNA replicates conservatively
Explanation:
<em>The replication of the DNA is </em><em>semi conservative.</em><em> This means that newly replicated double helix DNAs usually consist of one parental strands and one newly synthesized strands. The parental DNA unwinds and each strand serves as template for the synthesis of complementary strands.</em>
In the case of XNA, the two strands of parental XNA were found intact, meaning that the newly produced XNA consist of two newly synthesized strands. This thus means that the replication process is conservative.
Hence, unlike DNA replication that is semi conservative, XNA replication is conservative.
Answer:
When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
Explanation:
The binding allows the nerve impulse to travel through the receiving neuron.
Sustainability refers to how a system remains biodiverse and productive over long periods of time. Succession is a series of predictable changes that occur in a community over time. After a fire, volcano, or other disaster, succession enables an ecosystem to recover.
Answer:
Mountains are prominent landforms that have significant heights above sea level and/or the surrounding land. They are steeper than hills. A mountain or mountain range usually has a peak, which is a pointed top. Mountains have different climates than land at sea level and nearby flat land. Climate is the weather over an extended time period for a specific area. The climate of mountains tends to include colder weather, wetter weather, and thinner air. Thin air refers to the fact that at the higher altitudes of a mountain there is less oxygen to breathe. Also, mountains generally have less hospitable conditions for plants and animals. This leads to quite different evolutionary adaptations for those plants and animals that make higher elevations their home.
Coming to an agreement can sometimes be difficult.
