Answer: IQUID WATER DUE TO LOW ATMOSPHERIC PRESSURE WHICH IS LESS THAN 1% OF THE EARTHS EXCEPT AT THE LOWEST ELEVATIONS FOR SHORT PERIODS. ( FOR FURTHER INFORMATION GO TO MARS - WIKIPEDIA https://en.m.wikipedia.org)
Explanation: MARS IS THE 4TH PLANET FROM THE SUN . IN MARS THE IRON OXIDE PREVALENT ON ITS SURFACE GIVES IT A REDDISSH APPEAREANCE THAT IS DISTINCTIVE AMONG THE ASTRONOMICAL BODIES VISIBLE TO THE NAKED EYE.

The genes in a population give forth the genetic variability across a population (genotypes). In addition, occasional mutations of these genes in a population increase this genetic variability. Hovever, natural selection only favours reproduction of individuals with genes that are favourable in the environment/habitat. Therefore, natural selection has no foresight but is rather pegged on being an ‘opportunistic’ process.
Answer:
Based on their body <u>structure</u><u>,</u> flatworms and rotifers were not thought to be closely related. However, <u>bilateral symmetry and body texture</u><u> </u>showed that they are a <u>soft-bodied</u> group.
Explanation:
- Flatworm belongs to phylum Platyhelminthes and Rotifera belongs to phylum Rotifera.
- Their body structure may be different but both of them have a bilaterally symmetrical body.
- Both are aquatic animals.
- Flatworm is made up of ectoderm endoderm and mesoderm and has circular and longitudinal muscles. Rotifera is made up of skeletal and visceral muscles. So, they are soft-bodied animals.
I wish you added the diagram but I can tell that the long strings are the spindle fibres.
