<u>Answer:</u>
<em>It is not true to say that common ancestors occurs only within a single species rather two species with similar traits might have a common ancestor. </em>
<u>Explanation:</u>
If the ancestor is same for both the species then it is said that both the species are closely related and share common ancestor with similar evolutionary relationship.
Phylogenetic tree are drawn and studies are done to understand the ancestor of a species. The evolution has occurred from the ancestor to the new species formed.
Answer:
Urinary bladder - superior mesenteric ganglion
Explanation:
The inferior mesenteric ganglion is located in the center of the abdomen where the inferior mesenteric artery begins. The axons of postganglionic neurons extend through the hypogastric plexus. These neurons then innervate the blood vessels of several organs like the rectum, urinary bladder, and distal colon, etc.
The postganglionic neurons from superior mesenteric ganglion innervate the blood vessels of the small intestine and proximal colon.
Calcium ion is responsible for Muscle Contractions.
Answer:
Photosynthesis a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities
they need sun water and CO2
Explanation:
Hypothesis: I believe an increase in temperature would lead to a decrease in surface tension.
Here's why: As the temperature increases, the molecular interaction between the liquids molecules becomes weaker because the hydrogen bond is the main factor for association between two molecules. It is a very weak bond to begin with, so when the temperature increases, it just further weakens it.
