Answer:a. mitosis
Explanation: mitosis is a type of cell division found in somatic cells.
The daughter cells contains the same number of chromosomes as the parent cell.
Mitosis involves four stages namely;prophase, metaphase, anaphase,telophase.
There is also an interphase,of normal functioning of the cells.
Mitosis is important in asexual reproduction , regeneration and replacement of lost cells.
It also causes growth in organisms.
Unlike meiosis , crossing over does not occur in mitosis thus there is no variation in daughter cells
Idk bro i just want points plz dont report me follow me onna gram @nawff.justin
Answer:
Have larvae which are motile and move via the motion of cilia. (Ans. A)
Explanation:
Sponges: They are belongs to porifera phylum and defined as the simplest species. In sponge for particular function they are containing specialized cells, and they lack true tissues. All sponges are marine or aquatic in nature.
Sponge lives in contact with water because it helps them to excretion, gas exchange, and feeding. They can filter out the food, eliminate waste, and absorb dissolved oxygen with the help of body structure of sponge is dedicated to moving water.
Sponges produce motile larvae through the process of sexual reproduction, and move with the motion of cilia or budding formation through the process of asexual reproduction.
