Since we are mammals, primates, and hominoids, we have a lot in common with all of these other animal species, especially with our closest relatives, the apes. Our species, Homo sapiens, belongs to the genus Homo, but we are also hominins. Knowing our evolutionary history means knowing what we share with other primates as well as what has transpired in the 7–10 million years since we split from other African ape lineages. or more precisely, what transpired during the two million years of our own genus' existence. There is strong evidence that over the Pleistocene, our lineage endured substantial modifications to their bodies, behaviors, and ecologies, which led to the emergence of a human niche. This essay provides an overview of the significant parallels and distinctions between apes and humans.

what do hippopotamus eat
Grass
Explanation:
Hippos have a healthy and mostly herbivorous appetite. Adults eat about 80 lbs. (35 kg) of grass each night, traveling up to 6 miles (10 km) in a night to get their fill. They also eat fruit that they find during their nightly scavenging, according to National Geographic.
Consider the scenario.
A scientist sets up an experiment to see how sugar in the diet of
rats affects their weight. The scientist feeds one group of rats a
diet high in sugar, another group a diet of moderate sugar levels,
and a third group a diet low in sugar.
All of the rats in the experiment are the same species and age
and start the experiment at a healthy weight. The rats also
receive the same kind of sugar.
What is the dependent variable?
A. amount of sugar
B. species of rats
C. starting weight of rats
D. final weight of rats
Answer:
amount of sugar is the independent variable
Which of the following reasons explains why electrical cords are plastic coatings with metal wires on the inside?
Explanation:
metal has high electrical conductivity,but so you don't get electrocuted the metal has plastic coating because Plastic has low electrical conductivity
Why was the need for catalyst in the origin of life important?
Answer:
Catalysts are integral in making plastics and many other manufactured items. Even the human body runs on catalysts. Many proteins in your body are actually catalysts called enzymes, which do everything from creating signals that move your limbs to helping digest your food. They are truly a fundamental part of life.
Over the years, scientists have developed several systems for the classification of organisms. From the late 1960s, organisms had been classified
according to a five-kingdom system. This classification system model was based on principles developed by Swedish scientist Carolus Linnaeus, whose
hierarchical system groups organisms based on common physical characteristics. This system recognized five kingdoms: Monera (bacteria), Protista,
Fungi, Plantae, and Animalia. The scheme divided life into two main divisions based on cell structure: the Prokaryotae (bacteria) and the Eukaryota
(animals, plants, fungi, and protists). As scientists learned more about organisms, classification systems changed. Genetic sequencing has given
researchers a new way of analyzing relationships between organisms. The current system, the three-domain system, classifies organisms primarily
based on differences in ribosomal RNA (rRNA) structure. Under this system, organisms are classified into three domains and six kingdoms. The domains
are Archaea, Bacteria, and Eukarya: two prokaryotic domains and one eukaryotic. Recent work in the classification of life has shown that what was once
called prokaryotes are much more diverse than previously suspected. The prokaryotic domains also represent two distinct kingdoms, the Eubacteria,
and the Archaebacteria, and are as different from each other as either is from the Eukaryota. The kingdoms are Archaebacteria (ancient bacteria),
Eubacteria (true bacteria), Fungi, Plantae, Protista, and Animalia. The Eukarya domain includes eukaryotes or organisms that have a membrane-bound
nucleus. Eukaryotes have rRNA that is distinct from bacteria and archaeans.
Can you distinguish life in the thee domains and kingdoms?
The single feature that separates the domains in the cladogram is cell structure.
Based on this classification system, we can say that plants and animals are more alike than plants and
bacteria.
The domains Archaea and Bacteria differ from each other biochemically.
The domains Archaea and Bacteria both have organisms composed of prokaryotic cells.
The Archea are more closely related to the Eukarya than they are to the Bacteria.
According to this cladogram, scientists believe that all kingdoms evolved from a common ancestor HELP!!!!!
