Answer:
Small leaves
Explanation:
These ensure that less water is lost from the plant by transpiration because the leaf has a smaller surface area.
Answer:
<h2>Its true!!</h2>
Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!
Answer:
RNA Polymerase plays an important role in the process called transcription which result in the in the synthesis of RNA from DNA molecule.
Explanation:
RNA polymerase helps in the addition of ribonucleotides in the growing RNA strans that is synthesized from template DNA .
one ribonucleotide is joined to the adjacent ribonucleotide by the formation of phosphodiester bond.
RNA polymerase is named so because this enzyme helps in the polymerization of ribonucleotides leading to the formation of a Primary RNA transcript.
Answer:
The correct answer is: do not enter into a plexus and directly connect to the structures they supply.
Explanation:
<u>The </u><u>anterior rami</u><u> of the thoracic spinal nerves </u><u>from T1 to T11</u><u> give birth to the </u><u>intercostal nerves</u>, which are part of the somatic nervous system.
The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, <em>directly connecting to the structures they supply</em>.
The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.
