Ribosomes are microscopic machines found within all living cells. Found on the rough endoplasmic reticulum and in the cytoplasm, the main function of ribosomes is to synthesize proteins. Ribosomes are able to make proteins by “reading” information contained within messenger RNA (mRNA). The information contained within the mRNA contains the instructions for the ribosome to assemble the proteins bit-by-bit.
Proteins are made up of chains of organic molecules called amino acids. Ribosomes grab amino acids and link them together to create proteins in a process termed translation. During translation, every protein must be folded correctly in order to function properly.
Another of the ribosome's function is to mediate the proper folding of proteins.
Answer:
Angiosperm
Explanation:
The mitochondria of flowering Angiosperm plant are the largest. The size of these mitochondria varies from 1.86 million bp to 2.4 million bp. It is also the most complex one as it carries large number of repeating units which allows multiple permutations for recombination. This allows generation of mitochondria of varying sizes with in the same species.
It is least gene dense as the inter regions are highly expanded. One of the most distinguishing feature of these mitochondria's are that they contain polypeptides. These polypeptides are basically non functional but have potential to evolve into functional one.
Answer: A, the white mice are able to reproduce faster (the mouses only differ in color).
Answer:
pulse
axon
action potential
frontal lobe
hypothalamus
occipital
dopamine
Before receiving a nerve impulse, a neuron is at its resting potential, with more negative charges inside the cell than on the outside of the cell. When the neuron receives the nerve impulse, it is depolarized, allowing positive ions to flow across the cell membrane into the neuron. This is called an action potential, and the action potential travels the length of the neuron, taking advantage of the myelin sheath on many neurons. Once the signal has traveled through the neuron, the sodium-potassium pump repolarizes the cell, restoring the resting potential of the neuron.
