Answer:
C. the sympathetic division of the autonomic system.
Explanation:
The sympathetic nervous system is one of the divisions of the autonomic nervous system that controls involuntary body functions in the body. The sympathetic nervous system is said to stimulate the fight-or-flight response of the body when the body senses threat, or is exposed to a stressor. These fight-or-flight responses are generated in the body in form of physiological changes in order to put the body at top alert to focus on dealing with the stressor.
Physiological changes that are stimulated by the sympathetic nervous system as fight-or-flight responses include dilated pupils, inhibited digestive activity, increased respiratory rate, and release of glucose from the liver, which are all stated in the question. It is the sympathetic division of the autonomic nervous system that controls all these activities.
Answer:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
Answer:
Transcription
Explanation:
This occurs in three steps itself: initiation, elongation, and termination
Initiation (beginning)
- RNA polymers bind to a promoter on a gene
- DNA then unwinds to be "read" by an enzyme
- DNA now ready to make mRNA strand
Elongation (Second step)
- nucleotides are added to mRNA strand
- mRNA molecule is built after RNA polymers reads the DNA that unwound
- adenine (A) in DNA connects to a uracil (U) of RNA while connected to each other
Termination (End)
- RNA will cross a stop sequence in the gene (termination)
- mRNA done and disconnects or detaches from DNA
Hope this helps!
The more growfast used the higher the growth rates of carrots are expected to be.
Answer:
Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atomThe atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). A brief treatment of ionic bonds follows.
