Answer:
There are different evidences for evolution that includes anatomy, fossils, molecular biology and biogeography.
Molecular biology uses DNA and protein sequences that the genetic code reflect the shared ancestry of life. DNA comparisons used for the anatomical evidence.
All living cells are organized in the same basic DNA and use the same genetic code. Proteins derived from genes, all originate from the same set of amino acids. Comparing parts of DNA in various species has shown that even very different organisms still have significant parts of similar DNA. For example, in chimpanzees and humans have some precent of same genetic structure. In the amino chain, chimpanzees and humans have only one position, while humans and moths have 31 different positions.
<u>There are different advantages and disadvatages of each type of evidences are:</u>
Advantages:
- Anatomy share information about the similar physical structures shared by common ancestor (homologous structures)
- Fossils provide information about the extinct species.
- Molecular biology provide genetical relationship between organisms.
- Biogeography share global organism distribution and island species unique characteristics reflect evolution and geologic change.
Disadvantages:
- some of the structures such as forelimbs of human and birds seems homologous in structure as per comparative anatomy but they have evolved independently in each species.
- Fossils are impressions of past living organism and buried in earth surface rom long geological past, hence during this geological time there can be many changes in the fossil structure and can manipulate the evidences.
- Molecular biology has disadvantage of lack of assay specificity and sensitivity.
- organism can evolve and adapt according to different condition, hence Biogeography can not exactly tell the exact changes in the characteristics of organisms on the basis of particular geology.
Out of the following given choices;
a. Drink additional water to prevent dehydration.
b. Eat something with 15 g of simple carbohydrates.
c. Go to the first aid station to have glucose checked.
d. Take another dose of the oral agent.
The answer is B. The stated symptoms are symptoms of low blood sugar (hypoglycemia). The exercises drained glucose from her blood as the muscles used up the glucose in respiration. Since diabetics have flawed insulin protein that is incapable of enabling cells take up glucose and hepatocytes to make glucose, the blood sugar levels drop to critical levels that threaten body functions.
Temporal summation with an excitatory synapse will bring the membrane potential from the resting value closer to the action potential threshold.
<h3>
An action potential is produced by temporal summation in what way?</h3>
- A process known as "temporal summation" describes how repeated, equally intense noxious stimuli at a particular frequency result in an increase in pain. Results are typically achieved by comparing the first and last equal intensity stimuli's pain ratings.
- A high frequency of action potentials in the presynaptic neuron results in postsynaptic potentials that add with one another, and this is known as temporal summation.
- A postsynaptic potential's duration is greater than the time between receiving action potentials.
- Neurotransmitter binding at excitatory synapses causes the postsynaptic membrane to become depolarized.
- Chemically-gated ion channels open on postsynaptic membranes in contrast to the action potential in axonal membranes. While diffusing simultaneously, sodium and potassium move in different directions.
