Answer:
A. Both in mitosis and meiosis (II)
B. Mitosis
C. In both
D. Meiosis
E. Mitosis
Explanation:
Prior to every case of cell division in both mitosis and meiosis, the cell always ensures to duplicates its contents including its chromosomes. In both cases of cell division, the sister chromatids separates, apart from in meiosis I where homologous chromosomes separates to opposite poles. Only one cellular division occurs in mitosis which is involved in the growth and development of the diploid individual but in meiosis, two divisions takes place in the gametes (both male and female) to ensure that the haploid number of chromosomes is transfered from both parents each to the offspring ensuring a constant diploid offspring. Thus a diploid parent cell always produces a haploid daughter cell in the gametes during meiosis. In mitosis, the daughter cells are always identical to the parents cells.
Answer:
older, older
Explanation:
Fossils deeper in the ground are older.
Answer: c) and b) are correct.
The brain is encased in a protective bony or cartilaginous housing in craniates.
The anterior end of the nerve cord is elaborated to form a brain in craniates.
Explanation: The craniates include the chordata with well-defined heads. This includes mammals, reptiles and fishes. So we can discard the other answers. Because most craniates have functional jaws, and the adults do not lose their chordate characteristics. The last one does not apply as a specific feature because the tunicate have neural crest but are not recognized as craniata.
Breathing is an essential part of the works of the body. If you go a long time without breathing, you’ll die. The reason why you can go a long time without eating is because your body stores the fat to keep you going. Breathing is kind of the building block of the body.
