The answer is The law of ''gravity'' helps explain why the density of air as the altitude above earth's surface increases.
Answer:
Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide. Your digestive system absorbs water and nutrients from the food you eat. Your circulatory system carries oxygen, water, and nutrients to cells throughout your body.
Explanation:
Answer: The correct answer is-
Allopatric- option 2.
Sympatric - option 1.
Allopatric and sympatric are primarily the two major mechanisms for speciation ( formation of new species from an ancestral species).
In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.
On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.
Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.
Answer:
Memory and learning - Cerebrum
General bodily arousal - Cerebellum
Complex mental processes - Cerebral cortex
Connects two halves of brain - Cerebrum
Relax, dream, sleep - Hypothalamus
maintain homeostasis - pons
Regulates body circulation - Medulla
Emotions - Cerebrum
Tells senses - Cerebrum
tells nervous system - Cerebellum
Explanation:
Cerebrum is the largest part of the brain which controls emotion and senses of the body. It controls information of the body. Medulla Oblongata is the part of the brain which is just near the spinal cord. It regulates blood circulation. Hypothalamus is the part of brain which regulates sleep wake cycle of a person.
