Physics tell us how something was made because of the atoms that we have come from.
Answer:
C) Messenger RNA is transcribed from a single gene and transfers information from the DNA in the nucleus to the cytoplasm, where protein synthesis takes place.
Explanation:
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product, usually protein. Gene expression include steps such as
• transcription – part of DNA is copied into mRNA via an enzyme RNA polymerase
• RNA splicing – formed mRNA during transcription is not mature so it need to be proceed (e.g. excision of introns). Mature mRNA are then exported from nucleus to cytoplasm
• Translation – mRNA serves as information that codes for the synthesis of one or more proteins.
The answer is; SET B
Polar molecules interact well with water because there are charged. Water molecules are partially charged (the oxygen end is partially negative while the hydrogen end is partially positive). Therefore polar molecules can interact stably with charged molecules. The hydrophobic end is non-polar and is ‘water-hating’. When mixed with water, the non-polar region clumps up into globules so they don’t interact with water.
Answer:
B. olfactory information is not integrated in the thalamus prior to processing in the cortex, and the two systems are primarily processed in opposite hemispheres.
Explanation:
The thalamus is the main source of sensory information to the primary sensory cortex except for the sense of smell. The olfactory information from the sensory neurons needs to pass through the thalamus in order to reach the primary sensory cortex. Moreover, different thalamic nuclei, i.e., different groups of packed neuronal cell bodies that form the thalamus, have been involved in language. A bilateral thalamic activation (with left greater than right thalamic activation), as well as the activation of cortical regions associated with the language, is observed during tasks related to language processing. Language information is processed within the left hemisphere, while the olfactory information is processed in the olfactory bulb which is located on the inferior (bottom) side of the cerebral hemispheres.
Quaternary consumers eat the tertiary consumers and are carnivores.
