Vertebrates have a bilateral symmetry due to which their entire body is divided into right and left halves while the invertebrates either have radial symmetry or the bilateral symmetry. Therefore, option D is correct.
The other basic differences between the vertebrates and the invertebrates are that vertebrates have a spinal cord and a backbone while invertebrates lack them, vertebrates have well developed brain, lungs or gills in respiratory system and closed circulatory system.
Answer:
Meiosis is a special type of cell division used by sexually-reproducing organisms to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
2 divisions
4
Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes.
No genetic variation, all daughter cells are identical
Explanation:
Everyone could get cancer, most likely people who has a bad immune system, cancer develop when cells starts to reproduce in a certain way. There’s different types of cancer.
Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.
<h3>What are prokaryotic cells?</h3>
Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.
Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).
Examples of prokaryotes are as follows:
Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.
