Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.
The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.
At room temperature, a moderate number of oxygen bubbles were observed. The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.
Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.

The mouth is the beginning of the digestive tract; and, in fact, digestive starts here when taking the first bite of food
Answer:
No-till farming, which is the practice of leaving old stalks, provides cover from rain. The cover reduces water runoff and slows soil erosion. Contour plowing helps prevent erosion from heavy rains.

Answer:
1. You will be unable to smell
3. Your olfactory receptor cells will no longer be able to respond to molecules trapped in the mucus.
Explanation:
The Olfactory receptors are the receptors present in the olfactory neurons which detect different odorants or smell.
The olfactory receptors are embedded in the epithelium or mucous lining of the nose in which one extension of the cell body reaches the epithelium surface and branches into cilia like structures which sense the odour.
If the axons of the olfactory cells are broken then the cells will not be able to respond to the molecules trapped in the mucus and thus no detection of odour. The signal will not be generated in response and thus will not be sent to the brain. Thus, the person will not be able to smell.
Thus, Options-1 and 3 are correct.
Answer: a (weak) acid
Explanation: the solutions are mostly neutral but the pH shown by the indicator as a bright blue means it is slightly acidic meaning the pH is between 6 and 7.6
