Answer:
Explanation:
1. Depolarizes (depolarization of membrane causes opening of sodium channels which causes outward motion of emphatically charged sodium particles into the grid from the phones. This makes the network be profoundly positive charged and the cell film turns out to be exceptionally contrarily charged)
2. Sodium particles, ECF (As the layer depolarizes, the voltage gated sodium channels situated over the plasma membrane open up and the outwards motion of sodium particle happens deserting an enormous negative charge on plasma layer)
3. Invigorated (the muscle cells contain afferent and efferent neurons which help in transfer of data from muscles to mind and back to muscles. This progression of data happens by the methods for emission of synapses from the mind because of an upgrade)
4. Potassium particles, hyperpolarize (after the activity potential has been played out, the sodium particle channels near forestall further spillage of sodium particles in the ECF. Be that as it may, the potassium channels stay opened for longer occasions and consequently hyperpolarize the layer with a net profoundly negative charge)
5. Resting membrane potential (this procedure is known as transmission of motivation in a cell by a pattern of polarization, depolarization and hyperpolazation)
Explanation:
Solar eclipse
-The moon is in-between the earth and sun.
-only lasts for a few minutes.
Lunar eclipse
-The earth is in-between the sun and moon.
-can last up too an hour
Hope this helps!!
Answer:
DNA replication is important because without it, cell division could not occur. With DNA replication, the set of DNA of a cell can be duplicated and then each cell that results from division can have its own entire set of DNA, and cell division can theoretically continue indefinitely.
Answer:
C) Primary, tertiary and quaternary levels of protein structure
Explanation:
Primary structure; Covalent bond is present in form of peptide bond in the primary structuture of proteins. The amino acids are held together in the polypeptide chain by peptide bond.
Tertiary structure; Disulfide bonds are present between cysteine amino acids, that keeps the parts of polypeptide chain strongly attached to one another.
Quaternary structure; The Quaternary structure of protein is held together by hydrophobic interaction and disulfide bonds.
TEMPURATURE:
Raising temperature generally speeds up a reaction, and lowering temperature slows down a reaction. However, extreme high temperatures can cause an enzyme to lose its shape (denature) and stop working.
pH:
Each enzyme has an optimum pH range. Changing the pH outside of this range will slow enzyme activity. Extreme pH values can cause enzymes to denature.
DIFFERENT SUBSTRATES:
Increasing substrate concentration also increases the rate of reaction to a certain point. Once all of the enzymes have bound, any substrate increase will have no effect on the rate of reaction, as the available enzymes will be saturated and working at their maximum rate.
I got these explanations from khan academy :)
