Binary fission is the process of a bacterial cell going from singular to double. Therefore the correct answer would be: "During binary fission, a bacteria cell grows in size because DNA and other organelles are duplicated."
The wing of a bat is homologous to the flipper of a whale. Homologous structures are structures that have a similar ancestries and common traits but maybe not have the same function in an organism. For example the arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures.

Answer:
No, it isn't
Explanation:
An invasive species is characterized by an organism's appearance in an area it is not a native of, with a high capacity of reproduction that will cause it to be a threat to native species in that area. A species of organism is tagged "invasive" if it is foreign to a region/location and possess a high reproductive rate that spreads fast and causes harm to other species.
Based on the analogy given in this question about the escape of a rattlesnake from a zoo, it cannot be ascertained that it is an example of invasive species. This is because rattlesnakes may be native to that area and possess a zero threat level to the environment in terms of high spreading rate.
Mitosis helps in the growth by means of hyperplasia. It also helps in reproduction in single celled organisms.
Neuron and Red Blood Cells doesn't undergo cell division once formed.
Osteoblasts help in forming new bones and joining old ones after there's a fracture in bone.
<h3><u>Explanation:</u></h3>
Mitosis is the process by which a cell divides into two daughter cells. It helps in growth of multicellular organisms as well as reproduction in single celled organisms.
The Red blood cells are formed from the bone marrow megakaryocytes and never undergo mitosis. Same are the neurons which are formed from stem cells and never undergo cell division.
The osteoblasts come into action as the bone breaks. They diposit new calcium compounds between the broken part of bones. This leads to irregular growth of bones between them which is then remoulded and brought back to shape by osteoclasts and osteocytes.
