Answer: the expression of certain genes is affected by temperature
Explanation:
For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.
For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.
Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature
Vacuoles store water in plants
I just got this question on my test, the answer is D) glycogen. All excess glucose is stored long-term in the liver and muscle cells as glycogen when animals need it for energy.
Answer:
The prokaryote divides by asexual mode of reproduction.
Explanation:
The concept of species which defines a species as a group of individuals of a population which can interbred and produce a fertile progeny is applicable to the organism which can reproduce sexually.
Since the bacteria divide through asexual means and not through sexual ways therefore the concept of defining a species becomes complicated and does not apply.However the concept of species in prokaryotes is still a topic of research.
Thus, the biological concept of species is not applicable to prokaryotes.
<span>To summarize, when we swallow food, the food pushes on the soft palate, sealing off the nasal cavity and preventing food from entering the nose. The food then begins to slide down the esophagus. The swallowing reflex raises the larynx up under the epiglottis as the ball of food pushes down the epiglottis, sealing off the trachea; then the esophageal sphincter relaxes so the food passes through the esophagus. I hope this helps you! :D</span>
