Answer:
50
Explanation:
Contact occurs from a reservoir to contaminated surfaces or objects, or to vectors such as mosquitoes, flies, mites, fleas, ticks, rodents or dogs, etc. Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air.
When 50% of the population are infected, the disease transmission is said to be greatest.
The marine invertebrates of phylum Cnidaria are called corals. Corals are important as they build reefs in oceans and feed on planktons.
The given statement is :
<u>True</u>
The position of corals can be explained as:
- The corals are both a primary producer as well as the consumer.
- They take energy from algae through the mutual relation between both organisms. The corals feed on planktons, zooplanktons and phytoplankton for energy so they are consumers.
- The algae living in coral make food for them and corals produce oxygen.
Therefore, corals are producers.

I THINK:
The DNA strands unwind, and
RNA polymerase binds to the
template strand.
The tRNA moves through mRNA
with the activated amino acids
attached to it.
The synthesis of mRNA begins.
The amino acids assemble
to form peptide.
The mRNA undergoes intron
splicing and exits the
nucleus.
(sorry in advance if it's wrong)
