What are Nuc, Flag, ER, Mito, Chlora, Golgi, Ves, and Lys short for? What does each of these organelles do in a cell?
Nuc is short for nucleus; the nucleus is the control in the cell. Flag stands for flagella; the flagella is used to move the cell. ER stands for endoplasmic reticulum; the endoplasmic reticulum is used for helping things travel in the cell. Mito is short for mitochondrion; the mitochondrion is in charge of making energy. Golgi is short for golgi apparatus; Golgi does the moving chemicals around in the cell. Ves is short for vesicle; the vesicle is used to store things. Last but not least, Lys is short for lysosomes; a lysosome is used to break up food in the cell.
Answer:
They sleep on just one side of their brain at a time
Explanation:
Dolphins are different from fishes that can breathe underwater.
It is necessary for them to get to the surface of the water at intervals to breathe air.
While sleeping, dolphins allows one hemisphere of their brains fall asleep while the other half is fully conscious. This means that If the left brain is sleeping, the right eye stays open and if the right brain is sleeping, the left eye stays open.
This happens so they always know when it's time to surface and breathe and when to escape when there is trouble.
Answer:
The correct answer is - substitution.
Explanation:
Substitution mutations are the point mutations that are the mutations that least likely affect the trait of an organism or have no effect at all. Substitution mutations take place when there is only one nucleotide base is substituted by another nucleotide base in the DNA or RNA of an organism's genome.
In this case, there is no effect found on the protein formed by these DNA sequences. These substitution mutations generally found in somatic cells and have little to no effect at all.
The main reason is because they are heavy, and because they don't have to chase their food. They're not predators and their shells give them protection like running away gives protection to other herbivores.
