The behavior of zebras and other grazers banding together while grazing indicates their social behavior to protect themselves and their group mates from predators.
Grazing: It is a process in which herbivores roam from one place to another in search of grass, small plants, etc which are the main source of food for them. It involves forage search, selection of forage, and eating the selected forage. Different animals differ in the type and method of searching and eating forage. This different grazing behavior makes them different from one another.
Although, one common thing which is observed in these grazing animals is the practice of grazing in bands or groups. This is generally noticed in the area where they have more danger from predators so they practice this banding method as a protective measure because predators find it difficult to attack groups and they get less chance to kill a lone individual.

Heyy.
So i did the alternative activity for this assignment.
In task one I only did part F:
answer:
Weathering damage on Cleopatra's Needle, an Egyptian obelisk in Central Park, New York City, is compared to known weathering rates of granites in various regions. The detrimental influence of the city's environment in 83 years of exposure has been attributed by textbook authors to damage to this coarse-grained foliated granite. As evidenced by the original depth of inscription in New York, about 11/2 inches of maximum surface reduction had occurred. Granite reduction rates in humid regions were calculated to be as low as 0.0076 mm per year, and even lower in deserts. The majority of the damage to the obelisk was caused by rising moisture laden with sulfate salts in Egypt, according to the findings. The hydration pressure of these salts, combined with frost wedging, is responsible for the major damage to the monument, which happened during its first few years in New York.
In task 2 I only did part D
answer:
Two independent sets of observations on sand activities in relation to the flowing river are recorded as the water passes through the meandering river. Stream abrasion can affect the morphology of a stream or river dramatically over time. Because the water can start erosion with anything near it, erosion can impact human communities near rivers.
MAKE SURE YOU SAY THAT YOU DID THE ALTERNATIVE ACTIVITY!!!!
Crust is destroyed (apex) earth secience [sem2]
If the father had the gene BB (purebred & not carrying colourblind allele), then the answer will be a). All of their children will have normal vision with half of them carrying the colourblind allele.
If the father had the gene Bb (hydrid & carrying colourblind allele), then the answer will be d). 3/4 of their children would have normal vision whilst the last quarter would have colourblind males. This is due to them having to receive one colourblind allele from their mother on the X chromosome & one colourblind allele from their father on the Y chromosome.
