In biological classification, the organisms are grouped on the basis of their cellular structure, presence or absence of cell wall, presence or absence of a membrane-bound nucleus, motility, ability to produce food, mode of reproduction, and mode of nutrition. They are classified so as to distinguish the differently related organisms from each other and to study evolution, as well as better understanding of the biological system.
Hello there!
Well, that sentence is easy to memorize because it is short. Compare to what I have to memorize :)
How can I remember the definition?
Well, personally, I used different strategies to study Biology.
The first one "Flashcards".
Not every students like flashcards, but I do. In front of the card, you write "Gene". Then at the back of the card, you write the definition of it.
You keep reading it for like 3 times then you'll remember it.
Another strategy I used it writing it down. And this comes after you finished with the flashcards.
Take a piece of paper and write the definition down without looking at the flashcard. Write it down several times.
The next strategy is to test yourself. Leave it for like 4 minutes and go do something else. (Personally, I usually listen to music).
Then after 4 or 5 minutes, come back to it. Without looking at the flashcards or the paper, try to repeat the definition in your mind. Then repeat it out loud. Then write it down again to see if you remember the correct grammars. For example, you might don't remember how to spell "Chromosome".
That should be enough! :)
I used these tips to study Anatomy and some other science stuff. It works for me. I hope it works for you too.
As always, it is my pleasure to help student like you!
Answer: summation
Explanation:
The process which determine if an action potential will be generated or not depends on the combined effects of the signal inputs from multiple sources of synapse or from the repeated signals from the same synapse.
If the input signals reach the threshold voltage, action potential will be generated. (all –or –none principle).Therefore, this process is a determinant of the likelihood of action potential generation and it is called summation.
Summation is the ability to integrate multiple PSPs at multiple synapses.it is the process that determine if an action potential will be generated by combined effects of inhibitory or excitatory signals.
Based on the pathways and voulme of applied stimuli in the presynaptic neuron;
The signals can be temporal summation ( consecutive signals produced from the same synapse)where action potential of high frequency in the PSN generated action potential in the post synaptic neuron, which summate with one another. Or Spatial where signals inputs are from multiple presynaptic cells.
I would say answer A. A silent mutation is a mutation that occurs but it doesn’t change the amino acids within a sequence. So I’d say “The Amino Acid chain is not changed even though the nucleotides sequence on the Original DNA is different from the Mutation DNA
Blue whale, mushroom - heterotrophs
rosebush, algae, pine tree - autotrophs
