Answer:
Multicellularity Cellular
wall made of cellulose
Chlorophyll
Mobility in mature individuals
Explanation:
Multicellularity is because they have multiple cells in their conformation.
The cellulose wall that forms them usually provides the function of protection, maintenance of osmolarity, among others.
On the other hand, chlorophyll is what makes them independent individuals at the time of feeding, and in this way they have the necessary energy that consists of motility, which is a transport mechanism.
Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
Answer:
Do you mean the definition?
I think it is "population density". Population density is the number of individuals per unit area or volume.
Explanation:
They would work out how old the fossil was to see how old the egg was
I believe it is 'Common Descents'
