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.
Answer:
The sternum, thoracic vertebrae, and ribs protect the heart and lungs.
Explanation:
The skeleton can be divided into the <em>axial skeleton</em> (the skull and the vertebral column), <em>visceral skeleton</em> (ribs and sternum) and the <em>appendicular skeleton</em> (extremities).
The function of the <em><u>visceral skeleton</u></em> is to <em>support and protect</em> the first portion of the digestive and cardio-breathing apparatus.
In mammals, the second part of the vertebral column (thoracic vertebrae), the ribs and the sternum delimitate a protective box for lungs and heart.
b) cytosine pairs with guanine in both. literally in dna replication,
<em>adenine goes with thymine</em>
<em>thymine goes with adenine</em>
<em>guanine goes with cytosine</em>
<em>cytosine goes with guanine</em>
hope this helps mina! :) <3
