Both transcription and DNA replication are essential and significant genetic mechanisms.

Transcription is a process where the genetic material i.e. DNA  is getting converted or transcribed to RNA by an enzyme RNA polymerase.

Whereas the DNA replication is a process where, doubling or copying of DNA  from original DNA (identical replica copies). Which is the basis for biological inheritance.

nirvana33 [79]

Answer:

d. The species diversity of plot 2 is greater than that of plot 1.

Explanation:

Species diversity of an area depends on its species richness and species evenness. Species richness is the number of species present in that area. Species evenness measures how evenly these species are distributed.

Here, both plot 1 and plot 2 have same number of species. They both have four species of trees ( maple, birch, oak and pine) hence their species richness is same. However plot 1 has 85% maple trees and the rest three species make the remaining 15%. Plot 2 has more even distribution as 35% of trees are maple trees and birch and oak also have similar frequency with 25% and 35% respectively. Hence, plot 2 has more evenness.

Species diversity depends on both richness and evenness. Since plot 1 and 2 have same richness but plot 2 has more evenness, plot 2 has more species diversity than plot 1.

Why are many cells wired together in a typical photovoltaic panel
Harrizon [31]
It would have been easier to answer the question if there would have been some options to choose from. I am answering the question based on my knowledge and hope that it helps you. Many cells are wired together in a typical photovoltaic panel because of increasing the amount of electricity generated.

Which of the following is not a result of olimate change partially caused by burning fossil fuels? a. Leaves changing color in t
Verdich [7]

Explanation:

An environment's biology includes both abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem. These factors lead to a gradual change of an ecosystem over time; however, humans drastically impact the environment through over-exploitation and pollution- we disrupt normal abiotic and biotic interactions. Furthermore, human impact can lead to population die-offs and extinction events, along with food and water scarcity.

Human impact on the environment can manifest as:

  • overpopulation- natural resources are over used, and habitats cannot support human communities;
  • urban communities also expand by cutting down trees in deforestation- this leads to erosion and flooding;
  • burning fossil fuels- this reduces air quality and adds carbon dioxide to the environment leading to global warming;
  • pollution- adding contaminants to the atmosphere, waterways, soil etc.

Leaves change in the fall via a natural process; in green leaves the photosynthetic pigment, Chlorphyll a is produced in significantly lower amounts. Other pigment molecules that absorb and reflect different wavelengths exist in larger concentrations- their effect is more apparent, leading to visibly orange-red leaves.
