After suffering a brain injury by falling from a ladder, Zack's wife continues to tell the doctor that his personality has chang
ed. He used to be fun loving and carefree, but he is now more critical and yells at his children for seemingly little reason. Zack is likely to have suffered damage to the _____ lobe of his cortex. a. occipital
b. parietal
c. temporal
d. frontal
e. cerebral
According to the information given in the example, Zack is most likely to have suffered damage to his brain's frontal lobe becasue of the symptoms that he show such as a change of personality. Frontal lobe is located at the front of the brain and it is responsible for controlling functions such as judgements, decision making, personality traits, emotions and memory which are all among the most important things for someone to function properly. So the correct answer is D.
<u>Nitrogen-fixing bacteria</u> carry out the conversion of gaseous nitrogen to a biologically useful form of nitrogen
An energy pyramid illustrates that energy in the form of <u>heat</u> is lost to the surroundings as it is passed from one organism to the next
The energy role of a grizzly bear is that of a <u>consumer</u> because it cannot make its own food
<u>Decomposers</u> cycle nutrients from dead organisms back to the soil, where it becomes available for plants
The <u>Savanna</u> biome is characterized by its lack of trees, warm temperatures, and moderate rainfall
Explanation:
The nitrogen-fixing bacteria like Azotobacter which lives in symbiotic relationship in the rhizomes of leguminous plants. They convert inorganic atmospheric nitrogen gas through the action of its enzymes like nitrogenase to organic nitrogen in the form of ammonia, which is readily assimilated by the plants.
In an ecosystem, at each tropic level of an energy pyramid, only 10% of energy is utilized and transferred to the next higher tropic level whereas the majority of energy is dissipated as heat during various metabolic processes.
Decomposers also called saprophytes like earthworms, bacteria, fungi survives on dead and decayed remains of plants and animals and also on fertilizers, pesticides etc in the soil. They recycle the nutrients by breaking down the complex biomolecules into simpler forms and release back into the soil.
Grizzly bears being omnivores eat both plants and animals according to their availability. Hence they are both primary and secondary consumers.
Savanna is a grassland biome with a typical tropical wet and dry climate and receives moderate rainfall. Hence it cannot support trees but only have grasses.

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface.
