1. The right answer is d. A and B only.
On September 8, 2017, the earth shook in Mexico on the night of Thursday to Friday. An earthquake measuring 8.2 on the Richter scale hit the south of the country off the coast of Chiapas state, according to the US Geospatial Monitoring Center (USGS). The shock was felt as far as the capital, Mexico City.
2. The right answer is e. A, B, and C.
El Niño, and its La Niña counterpart, are large-scale oceanic phenomena of the equatorial Pacific Ocean, affecting the wind regime, sea temperature, and precipitation. El Niño and La Niña correspond to the two opposite phases of the coupled ocean / atmosphere phenomenon called ENSO (El Niño / Southern Oscillation).
Originally, the name El Niño was attributed by Peruvian fishermen to the small invasion of hot water that occurs every year along the coasts of Peru and Ecuador around Christmas - hence its name: in Spanish, El Niño means the child Jesus. By extension, the climatic phenomenon corresponding to the increased warming of surface waters near the coast of South America is now called El Niño. We know that it is linked to a cycle of changes in atmospheric pressure between the east and west Pacific, coupled with a cycle of ocean current along the equator.
Only ENSO has such a marked global impact. The other two ocean basins, Indian and Atlantic, are too small to allow such an important coupling between atmospheric and oceanic circulation, even if they also undergo deep water upwelling and trade winds.
C.No mutation can take place.
D.The population must be very small.
The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection.
The correct answer is C.No mutation can take place.
A low rate of mutations would help keep a population in equilibrium. The five assumptions of Hardy-Weinberg equilibrium are:
No gene flow can occur to increase variability in the gene pool. A very large population size is required to ensure allele frequency is not changed through genetic drift. Mating must be random in the population. Natural selection must not occur to alter gene frequencies.

A.Though unicellular, amoebas have all the necessary cell organelles and a well-defined nucleus, therefore fulfilling the characteristics of eukaryotes.
B.Though unicellular, amoebas have a nucleoid and no cell organelles, therefore fulfilling the characteristics of eukaryotes.

pelvic blades rotated inward
very long arms
thick rib cage
The correct answer is:
large jaw bone for muscle attachment.
Pelvic blades are rotated inward anyway, so it is not the right answer. Very long arms are characteristic of many other animals, as well as a thick rib cage is. This leaves a large jaw bone for muscle attachment as the right answer. This trait is an adaptation to eating large quantities of food.
Explanation:
By analyzing the fossil record we can tell how long life has remained on Earth, and how different plants and animals are compared to each other. The mandible, lower jaw or jawbone is the biggest, greatest and lowest bone in the human face. It affects the lower jaw and holds the lower teeth in place. The mandible sits below the maxilla. It is the only movable bone of the skull.
