Answer:
Because they are the most destruction waves
Explanation:
Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.

D. As oceanic crust sank beneath other oceanic crust, the cooling rocks aligned with the earth's magnetic field, which periodically reversed. This periodic pattern was seen on one side of a mid-oceanic ridge</span>
Answer:
The probability of producing a round and green plant from this cross is 3/16
Explanation:
This question involves two distinct genes coding for seed shape and seed colour. In the seed shape gene, allele for round seeds (R) is dominant over allele for wrinked seeds (r), while in the seed colour gene, allele for yellow seed (Y) is dominant over allele for green seeds (y).
A truebreeding plant means that the plant possesses homozygous genotype. Hence, a truebreeding pea plant with round and green seeds will have genotype: RRyy while true-breeding pea plant with wrinkled and yellow seeds will have genotype: rrYY. These two parents will produce F1 offsprings with genotype: RrYy (heterozygous).
When the F1 offsprings are self-crossed (RrYy × RrYy), the following allelic combinations of gametes will be produced by each F1 parent: RY, Ry, rY, ry
Using these gametes in a punnet square (see attached image), 16 possible F2 offsprings with a phenotypic ratio 9:3:3:1 will be produced
9- Round yellow offsprings (R_Y_)
3- Round green offsprings (R_yy)
3- Wrinkled yellow offsprings (rrY_)
1- Wrinkled green offsprings (rryy)
Answer: option D - After eating a large batch of salty popcorn, levels of salt in the urine increase
Explanation:
Homeostasis is the ability of a living organism to ADJUST its internal environment to maintain a stable equilibrium
FOR EXAMPLE: warm-blooded animals like humans allow blood vessels dilate during hot weather, and constrict during cold weather IN ORDER to maintain a constant body temperature.
Thus, after eating a large batch of salty popcorn, levels of salt in the urine increase due to the homeostatic mechanism of the ANTI-DIURETIC HORMONE stimulating reabsorbtion of water from urine, and excretion of excess salt.
