Answer:
roses
Explanation:
It occurs when an odor binds to a receptor within the nasal cavity, transmitting a signal through the olfactory system.2 Glomeruli aggregate signals from these receptors and transmit them to the olfactory bulb, where the sensory input will start to interact with parts of the brain responsible for smell identification, memory, and emotion.3
There are many different causes for alteration, lack, or disturbance to a normal sense of smell, and can include damage to the nose or smell receptors, or central problems affecting the brain. Some causes include upper respiratory infections, traumatic brain injury, and neurodegenerative disease.
initially as temperature increases rate of photosynthesis increases, but after reaching on climax, due to scarcity of water, it starts to decrease
<u>Answer</u>:
1. The purpose of the uninoculated control tubes used in the oxidation fermentation test is to serve as basis of the medium for the color comparison and that it is sterile.
2. It is necessary to use two controls in order to illustrate the no color change (green color) under both aerobic and anaerobic conditions.
3. The purpose of the experiment is to determine if the organisms utilize the carbohydrate and thus is fermentative. This will result in a color change from green to yellow.
Thus, the medium in one tube is sealed with a layer of paraffin to prevent diffusion of oxygen. This tube will show that the medium is unaffected by the lack of oxygen.
The second tube will allow the diffusion of oxygen. This tube will show that the medium does not change color naturally in the presence of oxygen. Thus, the color changes will be caused only by the fermentation process of the organisms.
Answer;
Angiosperms are grouped into monocots and dicots.
Explanation;
-Angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary. Their ability to flower sets them apart from non-flowering plants, also known as gymnosperms, allowing them a successful means of reproduction.
-Angiosperms can be divided into two categories, Monocotyledons (monocots) and dicotyledons (dicots). This distinction is based on the number of cotyledons, the food storage structures in their seeds. Monocots have one cotyledon while dicots have two.
