Answer:
How can you know what happened millions of years ago if no one was there to see it? Evidence and observation are the building blocks of all scientific inquiry; ... of the fossil record, geological formations, and genetics attest to change having taken ... clues together into a cohesive explanation of the diversity of living things. Because of the specialized and rare conditions required for a biological structure to fossilize, many important species or groups may never leave fossils at all. Even if they do leave fossils, humans may never find them—for example, if they are buried under hundreds of feet of ice in Antarctica.
Explanation:
The correct answer is "regulating important involuntary bodily functions such as blood pressure, heart rate, breathing and swallowing".
The area highlighted in this example is the posterior part of the brain, called the brainstem. The brainstem is comprised of three important parts, the medulla, the pons and the midbrain. The basic functions of this brain area include breathing, heart rate and sleeping.
The Prader-Willi syndrome (PWS) is due to the lack of expression of paternal genes of the 15q11-q13 region. It usually occurs sporadically, although some family cases have been described (<1%). Approximately 70% of cases are produced by deletions of paternal origin in the 15q11-q13 region. 28% of cases are due to maternal uniparental disomy and less than 2% are caused by imprinting alterations. A geneticist studying prader-willi syndrome should focus on chromosome 15, its structure or changes in the number, these anomalies are also related to other syndromes such as: Bloom Syndrome, Breast cancer, Isovaleric acidity among others.
Somatic cells are Body cells such as blood cells.
'<span>According to the following diagram, approximately how much time goes by between phase H and phase B? Explain your answer.'
I'll try to explain this as simply as possible. A single moon cycle is 29 and a half days. Each individual cycle takes approximately 3 and a half days to transition to the next phase, so i</span>f you want to know how much time goes by between phase H and phase B, you would multiply 3.5 by however many phases there are between H and B. The answer is approximately 11 or so days.
I hope this helped!
