Shrubs, pine trees, and kudzu are all plants that are common in southern states. What is another characteristic these plants have in common?
Question 5 options:
They are heterotrophs because they must consume their food from other sources..
They are autotrophs because they produce their own food.
They are all both autotrophs and heterotrophs because of how they get their food.

The image below shows the metamorphism of a frog. Which characteristic of life is being represented in this process?
Answer: The tubule is long and highly coiled to provide a large surface area for selective reabsorption. The coiling of the tubule reduces the speed of the flow of the filtrate to give more time for efficient reabsorption. The tubule is well supplied with blood capillaries to increase a steep diffusion gradient for selective re-absorption.
Explanation: Selective reabsorption occurs because during ultrafiltration, important components of the blood are filtered out and they need to be reabsorbed into the body.
Repressors are proteins that inhibit gene expression, They usually have DNA or RNA binding site which enables them to binde to the operator or associated silencers. Allosteric domain is the site for the binding of other molecules, such as corepressors and inducers that regulate repressor's activity.
Relative age only tells us the order in which events occurred, from the earliest to the most recent. Knowing the actual date of an event allows us to say exactly how old something is or how long ago it actually took place.
