Primates are a group of mammals
including humans, apes, monkeys, lemurs and lorises. The physical adaptations
that all primates share are; a fairly generalized skeletal layout that can be
used for many different modes of locomotion, specialized forelimbs, hands and
feet, a larger brain especially the cerebral cortex, an omnivorous diet, stereoscopic
vision that helps in the perception of depth and measuring distance and a small
number of offspring at birth.
Answer:
The rule of magnetism illustrated is the field lines are more concentrated at the poles and also about the direction of magnetic field.
Explanation:
- Every magnet has two pole, north pole and south pole. The like poles repel each other and unlike poles attract each other.
- The direction of magnetic field is from north to south that can be seen by the iron filling experiment.
- When the iron fillings are kept near the bar magnet, we observe that most of the fillings are attached to either poles.
- It is due to the fact that the concentration of magnetic field is highest at the poles.
It's either 1 or 4 (hfjsjhsjsjwjje)
Answer:
D
Explanation:
The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.
(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.
(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.
(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.
(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.
Commonly called the enterics due to the fact that they inhabit the intestinal tracts of humans and other animals.
