Answers
The primate family characterizes by having long arms they use to move, an improved visual system, 5 fingers, and prehensile capability. Options B, C and D.
What are the primates' morphological characteristics?
Primates characterize as having an elongated head that culminates in the snout.
They are pentadactyl, meaning that they have five fingers in their hands and feet. Their thumbs are opposable, providing the animal the prehensile capacity.
Their visual system tends to face both eyes to the front and see in colors, characteristics that improve their sight, as primates rely little on their smell sense and much on their sight.
They are quadrupeds with a svelte body and soft hair. Their tail is long. They move from tree to tree by making use of their extremities. They have a dental comb to clean themselves and others.
They are herbivorous frugivorous.
The three correct answers are,
b. the animal's eyes face forward with overlapping fields of view, providing a three-dimensional view and accurate judging of distance.
c. the animal has long flexible arms and a prehensile tail that help it swing from branch to branch.
d. the animal has five flexible fingers and toes, and an opposable thumb and big toe, all used for grasping tree branches and food items, such as fruits, leaves, and seeds.

Reduced vegetation on Earth results in _____.
Answers
Answer:
fragmentation of habitat, soil erosion, soil compaction, and increased input of sediment into waterways.
Explanation:
Reduced vegetation on earth will result in more carbon dioxide in the atmosphere because the plants will not absorb the rest.
The effects of plant removal on soil biota were similar to that in the dry season. For both seasons, understory removal had no significant effects on soil Physico-chemical properties (soil water content, pH, total nitrogen, and soil organic carbon) but the removal of all plants significantly decreased soil pH.
Expansive changes in tundra and boreal vegetation can have significant implications for physical and ecological processes, as well as impacts on communities. Vegetation change that alters land surface darkness influences albedo and surface energy balance.
