The answer to this question is true
1. The answer is; B
Transcription is part of the central dogma. It is conducted by the RNA polymerase enzyme that adds complementary bases too, the DNA is transcribed, on growing RNA strand. The RNA is processed (such as splicing) and the mRNA is then used to produced proteins in the process of translation conducted by ribosomes.
2. The answer is; C
Pollution is made up of individuals of the same species, while the community is made of an amalgamation of different species that interact. An ecosystem is composed of a community and its interaction with the biotic and abiotic factors in the environment and habitat.
3. The answer is; B
Helicases are important enzymes in DNA replication because they unzip the DNA strand and allow for the DNA polymerase to access the single strands and replicate the DNA. They use the energy from ATP to break the hydrogen bonds between the two strands.
4. The answer is; B
The climate in the temperate forest is ideal for most life because they receive rainfall throughout the year while the temperatures also remain at a small optimum range throughout the year. This is capable of supporting a wide variety of vegetation and hence also support a large variety of animals.
5. The answer is; C
Many food chains interconnected together make up a food web. A food chain begins with primary producers which are mainly photosynthetic plants. These plant harness the energy of the sun into biomass. The transfer of this energy and biomass occur mainly through interactions such as predation. Primary producers are consumed by primary consumers that are consumed by secondary consumers that are consumed by tertiary consumers.
Explanation:
by photosynthesis sunlight provides the food the tree needs
