Bdelloid rotifers appear to reproduce only asexually. which outcome, if found in this group, would demonstrate that sexual reproduction may occur in <u>meiotic</u><u> </u><u>cells</u><u> demonstrate sexual reproduction</u>.
Parthenogenesis is an asexual reproductive method used by bdelloids. This indicates that fertilisation is not necessary for the development of embryos from eggs. Sex has a lot of benefits from a biological standpoint.
For instance, during sexual reproduction, the child receives one pair of genes from the mother and one pair from the father; as these genes come together, they frequently get rearranged into new combinations. Asexual reproduction speeds up the spread of organisms, but it also creates clones with little genetic variation.

Answer:
it's called nitrogen fixation
Answer: Water erosion
A scientist observes the ocean tides moving large amounts of sand away from the beach is a evidence for natural process which is known as water erosion. Water erosion is a process of removal or detachment of upper soil layers from its's original place due to the effect of water. The rate of erosion may be rapid or slow depending upon the soil, the landscape and weather conditions. The beach exhibit sandy soil whose particles are not connected or aggregated with each other and not with the surface over which it is present. Therefore, sand being loose soil is taken away by oceanic tides due to water erosion.
Answer:
Global warming
Explanation:
Global warming is defined as the heating of Earth's surface, atmosphere and oceans due to the result of human activity such as burning of fossil fuels that releases methane, carbon dioxide (CO2), and other greenhouse gases into the atmosphere.
Global warming is the result of action at one part of the world but it affects the other part of the world where human intervention is zero.
Due to global warming, there is extreme changes in climate which is resulting in melting of glaciers, rise in sea levels and loss of biodiversity.
Hence, the correct answer is Global warming.
