Answer:
C
Explanation:
<em>A person with garbled speech may have experienced damage to the frontal lobe portion of the brain.</em>
<u>This is because the left portion of the frontal lobe of the brain is an area that has been touted to be responsible for the control of speech in humans. Research in the past has shown that damage to that region of the brain affects the formation of spontaneous speech as well as motor speech control.</u>
Hence, garbled speech in someone that has experienced stroke can be attributed to damage to the frontal lobe.
Correct option: C.
Answer:
Idiopathic thrombocytopenic purpura or ITP is also known as Immune thrombocytopenic purpura that is a disorder in which there is an abnormality in the clotting of blood due to a decreasing number of platelets in an individual.
Platelets plays role in clotting the blood to prevent bleeding so this disorder leads to easy bruising, bleeding gums, and internal bleeding. It is an autoimmune disorder as in this case, an immune reaction takes place against one's own platelets.
It occurs in all age and sex groups however, it occurs normally in young children and females more often.
The event was volcanic eruption.
The second largest volcanic eruption took place in June 1991. The volcanic eruption took place in the Mount Pinatubo (a chain of volcanoes along the Luzon arc) on the island of Luzon in the Philippines. After the millions of tons of sulfur dioxide were discharged into the atmosphere, resulting in a decrease in the temperature worldwide over the next few year.
Answer:
Most food webs have between 4 and 5 trophic levels
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers only absorb 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow. It passes through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is eventually dissipated in the environment.
There is an energy transfer from each trophic level to the next, and each level only uses 10% of this energy. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The rest of the energy is used by the organisms in their own metabolism or dissipated as heat to the environment.
The progressive reduction of energy determines the number of trophic levels, which, in general, turns to be between 4 and 5.
