Answer:
B. identifying the regions of human DNA that are transcribed into RNA
C. identifying the regions of human DNA that bind to proteins
D. analyzing the regions of human DNA that vary among individuals
Explanation:
The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.
Answer:
Nodes of Ranvier are gaps in the myelin sheath coating on the neural axon. The myelin allows the electrical impulse to move quickly down the axon. The nodes of Ranvier allow for ions to diffuse in and out of the neuron, propagating the electrical signal down the axon.
Answer:
The individual was exposed to Loa loa at some point.
Explanation:
The helminth Loa loa , also called the African eye worm , is a type of nematode which can lead to loiasis .
Laiasis is a disease spread to the western and the central Africa .
The disease is generally found found in <u>less than 30 % of the population .
</u>
Travelers are more susceptible on developing the symptoms than the native population .
Answer:
The correct answer is "sea star living deep in the ocean".
Explanation:
A sea star living deep in the ocean isaAn example of an ectothermic organism that is not able to control its body temperature. However, sea stars are able to sense temperature and have few behavioral options to regulate it. Usually, a sea star lives in waters that are between 72 and 78 degrees Fahrenheit. If the water reaches 88 to 95 degrees Fahrenheit, the sea star responds by shucking their limbs.
The answer is B... they are poisonous because of the plant they eat
