Answer:
The sun has an arrow leading to the decomposer, the sun should be at the bottom of the pyramid
Explanation:
The sun is the ultimate source of energy that provides energy to the producers. The producers use the light energy to synthesize the chemical compound. The energy from the producers is transferred to the primary consumers and their energy is transferred to the next levels. The sun cannot be decomposed by decomposer so the arrow from the sun leading towards the decomposer is not right.
Answer:
hello there
Explanation:
A protein domain is another phrase describing what type of structure of a protein? None of these- The protein domain is an organizational unit that is distinct from the primary, secondary, tertiary, and quaternary levels of organization.
The question is incomplete as it does not have the option which are:
A. The lagging strand glows more because its RNA primer is nearer the replication fork.
B. The leading strand glows more because it is elongated nearest the replication fork.
C. The lagging strand glows more because it forms the "trombone loop."
D. The leading strand glows more because it forms the "trombone loop."
Answer:
A. The lagging strand glows more because its RNA primer is nearer the replication fork.
Explanation:
The process of DNA replication requires the primase enzyme which synthesises RNA primers from the DNA strand. The RNA primers bind to the site near the replication fork from where the replication begins.
If the ribonucleotides are radioactively labelled then the strand which glows brighter than the other will be the lagging strand as the lagging strand is synthesized by the template DNA running in 5' to 3' direction as a result of which the RNA primer moves towards the replication fork.
Thus, Option-A is correct.
Answer:
The impact of so many humans on the environment takes two major forms: consumption of resources such as land, food, water, air, fossil fuels and minerals. waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases.
