Answer:
The correct answer would be an option B.
Asexual reproduction is a reproduction in which offspring are produced from a single parent.
It does not involve fusion of gametes and crossing over due to which the offspring contain identical genome as that of parents.
This reduces the genetic diversity in a population due to which all the organisms of a population are at equal risk of extinction under unfavorable conditions such as high temperature, antibiotics, change in pH of surrounding medium et cetera.
Thus, the disadvantage of asexual reproduction is the lack of genetic diversity due to which a single antibiotic is able to kill millions of genetically identical bacteria.
Answer:
Oxygen is one and i can't think of others
Explanation:
The ganglia are formed from the cell bodies of a group of neurons. The ANS or autonomic nervous system associates with the CNS (central nervous system) and the somatic nervous system with the help of ganglia. The ganglia accommodate the cell bodies of sensory (afferent) and motor (efferent) cell bodies of the ANS.
The sympathetic ganglia are situated near to the central nervous system. The two sympathetic ganglia, which locate the cell bodies of post-ganglionic cell bodies are sympathetic trunk ganglia (situated alongside the vertebral column) and collateral ganglia (anterior to the vertebral ganglia).
Answer:
23 pairs in meiosis 1 and 23 numbers in meiosis 2.
Explanation:
There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.
