Answer:
The two main processes of cell division, meiosis and mitosis, have in common their main steps. In both cases the metaphase ( pairing of homologous chromosomes), anaphase (migration of chromosomes to the ends) and telophase (beginning of DNA decondensation and cell division) are very similar.
The greatest difference occurs in prophase I of the meiosis, which involves the process of recombination (cross over), resulting in variability in the gametes.
Another difference is that meiosis is a reductional process, where the final result of meiosis will be gamens with half of the genetic information, and in mitosis both cells will be equal.
The correct option is C.
The hypothalamus is an area of the brain which contain a number of nuclei which have varieties of functions. The hypothalamus link up the nervous system and the endocrine system through the pituitary gland in the brain. The hypothalamus is responsible for the secretion of orexin hormone, which regulates appetite, wakefulness and arousal. Hypothalamus is also responsible for monitoring the secretion of other appetite hormones.<span />
Answer:
B
Explanation:
Competition is defined as an activity done by two opposing sides, both of which are trying to do better than the other.
The organism is a plant.
Plants are photosynthetic and autotrophic organisms, characterized by plant cells containing chlorophyll. The plants do not have locomation devices and are therefore immobile.
Photyosynthesis starts from inorganic ingredients (CO2 and H2O) to give an organic molecule (glucose) and oxygen at the end.
