The answer is...
C) Medulla Oblongata
(The brainstem is made up of the Medulla Oblongata, Pons, Mesencephalon.)
Answer: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides.
Explanation: Amino acids are absorbed via a Sodium cotransporter, in a similar mechanism to the monosaccharides. They are then transported across the alabaster membrane via facilitated diffusion. Di and tripeptides are absorbed via separate H+ dependent cotransporters and once inside the cell are hydrolyzed to amino acids.
Answer: Depending on the nature of the signaling molecule, it may either bind to and activate a receptor protein embedded in the plasma membrane, or it may move across the plasma membrane and bind to a receptor protein in the cytoplasm.
Explanation: I found this answer on quizlet
Oligonucleotide primers associate by hydrogen bonding to specific sections; primers are then extended.
Answer:
Living organisms that are able to adapt to the environment (natural disaster) will increase in number while the ones such as warbles who can't adapt will die and go into extinction.
Explanation:
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.
Additionally, due to genetic variation within populations, some living organisms have a better chance of possessing good or beneficial traits being passed from the parent organism to her offsprings which enables them to survive a natural disaster.
Hence, if a natural disaster caused all warbles to go extinct, the natural disaster may not kill all living organisms due to natural selection.
