I know this because it was in my syllabus last year
Answer:
False
Explanation:
The basic cycle of energy shows how energy decreases as it moves through higher trophic levels in an ecosystem. In the first level, the primary organisms (such as plants) utilize energy from the sun to generate biomass through photosynthesis. In the second level, the organisms exploit primary trophic level organisms as food sources and thus obtain energy. Finally, in the third level, carnivores eat the herbivory organisms to obtain energy. At each trophic level, an important part of the energy is lost as metabolic heat; however, this energy can not be reused, this principle is known as the 'law of conservation of energy'.
Answer:
The motor area both has a homunculus and has descending projection fibers is primary motor cortex
Explanation:
The primary motor cortex has projections for the entire human body map, or homunculus. Axons from the primary motor cortex project from the frontal lobe to the spinal cord.
It may be muscle fiber which control pretty much things!
Answer:
A population of rattlesnake in the state of Florida.
Explanation:
A population refers to the group of individuals of a species present together in a defined region at the same time. All the members of a particular population belong the same species and hence, are able to interbreed to produce fertile progeny. Since they belong to same species, individuals of a population also share several common morphological traits.
Some of the attributes of a population are natality (the birth rate), mortality (the death rate), density (number of individuals per unit area), sex ratio, etc.
Therefore, the given example explains the population of the rattlesnake in the state of Florida.
