The tundra has trees, some grasses, large animals, and is usually cold. The desert on the other hand, Is usually hot, and has less animal and plant life. Deserts can be cold in some places though.
When an action potential does arrive at the terminal, the neurotransmitter must be quickly and efficiently released from the terminal<span> and into the synaptic cleft. The neurotransmitter must then be recognized by </span>selective receptors on the postsynaptic cell<span> so that it can pass along the signal and initiate another action potential.</span>
Answer:
Amino acids
Explanation:
Like a house, every molecule is formed of units (blocks) that determine their structure and function. Proteins have a diverse functions in the body and are very important in multiple biological processes. Proteins are molecules called polymers (molecules formed by monomers), the simplest units of proteins are the amino acids (building blocks). The amino acids are bind together by peptide bonds and when the chain of amino acids is less than 30 is called peptide and more than 30 is called protein. Every amino acid has a special structure and the type and number of aminoacids determinate the structure and function of the protein.
During glycolisys in cytoplasm, first step involves adding two phosphates to glucose molecule. This step requires the use of two ATP molecules. The next step is splitting 6 carbons glucose into two 3 carbons pyruvates. This step produces 4 ATPs and 2 NADHs. However, since we used up two ATPs during the initial phosphorylation, the net gain is only 2 ATPs
First I would use a magnet to get the iron filings out then I would use a sieve to separate the wood chips from the sand and salt. After this pour water into the sand and salt and put it through filter paper, the salt will go through as it is dissolved in water and the sand will be left behind. Place this salt solution into a dish and put it over a flame, the water will evaporate and leave the salt behind
