b)growth factors
c)the mitotic spindle
d)cancer cells
Answer:
a) Cyclins
Explanation:
The internal regulators of the cell cycle are cyclins and CDK (cyclin-dependent kinase). These are proteins that regulate the cell cycle in different checkpoints.
The cyclin proteins stimulate another kind of protein i.e. CDK, which helps in the entry and exit of cells in different checkpoints. The checkpoints are G1, S, and G2 phases. Without this protein regulation the cell cycle can't run properly, nondisjunction of chromosomes, and cancer may result.
The growth factors help in the migration of cells in different parts of the body. This causes cellular growth. These include hormones and enzymes.
Mitotic spindle/spindle fibers separate the double number of chromosomes and put them equally in 2 daughter cells. During the cell cycle, the spindle fibers are not active. It is active in cell division.
Cancer cells are uncontrolled growth of cells. This results due to the failure of cell cycle regulators. Thus cells divide rapidly.
is the attraction of two similarly charged ions
is the attraction of two oppositely charged ions
involves actual transfer of electrons
does not involve actual transfer of electrons
The answer you're looking for is Involves actual transfer of electrons. I hope that this helps you! Please leave brainliest answer if you can!

Answer:
Asexual reproduction is a method of reproduction for most of single cell organisms including yeast, in this type of reproduction a single parent generates new organism and new one is exact copy of parent both physically and genetically.
In yeast asexual reproduction is carried out by budding, its an asymmetric type of division in which first a protruding body is produced on its surface, it fully grows and forms bud later. When full grown, buds detach from the parent cell and grows independently. Instead of single bud, a chain of buds could also be produced at the surface of yeast.
