Answer:
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.
Explanation:
Answer:
Hotspot
Explanation:
Volcanoes can form in three different places: a convergent boundary, a divergent boundary, or a hot spot.
-At a convergent plate boundary, two plates collide and form a subduction zone. In the subduction zone, the denser, heavier plate goes below the more buoyant plate. The plate that goes under is subjected to immense heat and pressure and melts to form magma. This magma is less dense than the surrounding solid rock and rises to the surface through cracks in the plates to form a volcano.
- Volcanoes will form along divergent plate boundaries. A divergent boundary is when the plates move apart from each other. When the plates part, magma from under either plate rises and forms a volcano.
-A hotspot is the third place a volcano can form. This particular type is the least common. Hot spots are when thermal plumes from deep in the Earth rises. This heat, combined with the lower pressure at the bottom of the lithosphere, causes magma to form. The magma, as we discussed, is less dense than the surrounding solid crust and rises to the surface through cracks and channels and then erupts at the surface to form a volcano.
Answer:
The correct answer would be -provide detailed information about the research and drug and let the man decide if he wanted to withdraw from the research or take new drug.
Explanation:
In this type of case where there is a drug that is in on going study or in clinic trail which is showing promising result, investigator should provide the client or subject a comprehensive account of the drug with is pro and cons and side effects.
He should discuss about the both currently available drug in market and ongoing research drug and let the man decide whether he want to be part of the research or withdraw from the research.
Answer: Pacific Ocean
Marine life, are the plants and, animals and all other organisms that live in the ocean. The oceans cover 71% of the Earth's surface and contain 750,000 marine species. The Pacific Ocean is the largest ocean with the largest number of marine life such as coral reefs. It is where the deepest point in the world is located, the Challenger Deep in the Mariana Trench. Seventy percent of the fish comes also from the Pacific Ocean.
Answer:
20
Explanation:
Haploid cells contain a single copy of each chromosome. Diploid cells contain two copies of each chromosome. So if a haploid cell in an organism contains 10 chromosomes - the diploid cell will contain 20 chromosomes.
In humans, nearly all of our cells are diploid, and contain 46 chromosomes. Our haploid cells - the gametes (egg and sperm cells) - contain 23 chromosomes (one copy of each chromosome). When these fuse during sexual reproduction to form a zygote - the diploid state is restored and the zygote has 46 chromosomes.
