When there isn't enough room in the cell for two complete molecules of DNA, the prokaryote stops replication and undergoes cell division.
Answer:
Sexual reproduction:
Pros: leads to greater genetic variation.
Cons: requires more time and energy.
Asexual reproduction:
Pros: Does not require finding a mate.
Cons: Produce less genetic variation.
Explanation:
Sexual reproduction is a type of reproduction in higher organisms, in which new individuals are formed by combining genetic information from two different types (sexes) of individuals.
Advantage: Sexual reproduction leads to higher genetic variation due to recombination between genetic material of female and male gamete during meiosis.
Disadvantage: Sexual reproduction is a time and energy consuming process as it needs interaction between mates and organisms which are produced sexually require more time for development.
Asexual reproduction involves formation of new organisms from a single parent organism without gamete fusion.
Advantage: Asexual reproduction requires less time and energy as it does not require finding a mate.
Disadvantage: Asexual reproduction produces less genetic variations as it involves only parent organisms (no mixing of genetic information) and the only source of variations are random mutations.
Cerebral cortex
1. Emotion can invoke an autonomic response.
2. Sexual thoughts or image which can increase blood flow to the genitals.
Hypothalamus.
1. It activates the flight or fight response.
2. It is the major control of ANS.
3. It is the integrating center for thermoregulation.
Brainstem.
1. It is integrating centers for reflexes which control heart rate and blood pressure.
2. It is the integrating center for pupillary reflex
Spinal cord
1. It is the integrating center for urination, erection, defecation and ejaculation reflexes.
Answer:
A vesicle is a small, membrane-bound sac that transports substances in cells. The ER moves proteins and other substances within eukaryotic cells.
