Answer:d)mimosa plant folding its leaves when touched in an effort to keep them from being eaten.
Explanation:
The option which is not a characteristic of chordates is chloroplasts in their cells.
Chordates do have a dorsal supporting rod (vertebrates are types of chordates - they have a spine), a dorsal hollow nerve cord (within the spine), and pharyngeal pouches. However, they do not have chloroplasts, because that is a characteristic of photoautothropic eukaryotes, which chordates certainly are not.
Answer:
The correct answer is through anaerobic respiration in the cytoplasm.
Explanation:
Cellular respiration is of 2 types
1 Aerobic respiration Respiration that require oxygen to occur
2 Anaerobic respiration Respiration that do not requires oxygen.
During low oxygen level the body of runner keep up with the demand for energy by undergoing anaerobic respiration which includes Glycolysis.
During anaerobic condition the functionally active body cells undergo glycolysis and with each glycolysis 2 molecules of ATP are generated which can some how boost the energy supply within runner"s body.
Answer:
DNA replication a process of copying of a cell's DNA. DNA replication is semiconservative process which means that each strand in the double helix helps in the synthesis of new, complementary strand and conserve the parent template.
The Molecular mechanism of DNA replication is as following:
- The double starnded DN in binded with hydrogen bond, the enzyme helicase opens up the DNA at the replication fork.
- A single stranded binding protein prevent the rewinding of DNA and so binds to the DNA around the replication fork
- Topoisomerase prevent supercoiling at replication fork.
- The ezymes primase come in action and produces RNA primers which are complementary to the DNA strand.
- DNA polymerase III help to extends the primers and allow them to add to the 3' end, to make new DNA.
- DNA Polymerase then remove RNA primers and replace with DNA.
- DNA ligase blocks the the gaps between DNA fragments.
So, this is the molecuar mechanism of DNA replication.
These organisms that consisted only of unicellular were called prokaryotes.
