Answer:
It's a form of asexual reproduction!
Development of the offspring happens without fertilization in this type of reproduction.
The two main ways in which parthenogenesis happens is by apomixis or automixis. Through apomixis , the egg cells are produced by mitosis. Through In automixis, egg cells are produced by meiosis.
Mitosis = a part of cell cycle: replicated chromosomes are separated into 2 nuclei
Meiosis = type of cell division that reduces the chromosome number by half. So now there is four haploid cells that are genetically distinct from their parent cell.
Example:
An example of an animal that can use this reproduction is a bonnethead shark! Once a shark had a baby in a tank that only had three females!

The undulations on the cerebral cortex (the outer layer of the brain) are called gyri (ridges) and sulci (gorges). Also called the grey matter, the cerebral cortex is the core of brain functioning region with approximately 20 billion neurons.
It is believed that the cerebral cortex is highly folded to accommodate many neurons.
Answer:
c
Explanation:
Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
If you are talking about frequency in terms of waves, it is in seconds^-1
The answer is c. their gametes do not require water for fertilization to occur.
<span>Fertilization is the process in which two gametes fuse which first creates a zygote and then leads to the development of an embryo. Pollination is a transfer of male pollen to the female reproductive organ. </span><span>After pollen lands on the stigma, pollen tube begins to grow until it reaches an ovule which is inside the ovary. A nucleus of pollen will fuse with a nucleus of the ovule and that fertilization will occur. </span>
