Answer:
External fertilization usually occurs in aquatic environments where both eggs and sperm are released into the water Most external fertilization happens during the process of spawning where one or several females release their eggs and the male(s) release sperm in the same area, at the same time.
Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them In this case, the eggs are fertilized inside the female's body before they are released.
<span>In the skeletal muscle cells of vertebrates, as many as 38 molecules of ATP are produced from one molecule of glucose. This is less than might be expected, because electrons from NADH produced during glycolysis must be shuttled through the inner mitochondrial membrane at a cost.
</span>The energy of the electrons can be used to make ATP and in eukaryotes, glycolysis occurs in the <span>cytosol, outside mitochondria. </span>
Answer:
the genetic code is universal.
Explanation:
Answer:
Signal transduction
Explanation:
A signal molecule binds to a receptor.
A conformational change in the signal-receptor complex activates an enzyme.
Second messenger molecules are released.
Protein kinases are activated.
Target proteins are phosphorylated.can be defined as the process in which a physical or chemical signal is transmitted through a cell as a series of molecular events inform of protein phosphorylation are catalyzed by protein kinase and this ultimately result into a cellular response. However, the protein that is responsible for the detection of stimuli is commonly refers to as receptors or sensor.
B is the most efficient answer
