when a homozygous white rabbit (bb) is crossed with a heterozygous black rabbit (Bb). what proportion of white rabbits would the offspring have?
Answer:
Based on the Mendelian fashion cross,
bb is hetezygote reccessive.(white)
Bb is heterozyote dominant.(black)
Therefore,the the cross to show the proportion is below
Bb,Bb,bb,bb,
2 blacks(hetero zygote blacks) and 2 white.(homo zygote whites)
thus 2 of the offspring will be white, in 50%, of the number of offspring
Explanation:
Answer:
Point A - Intrusive igneous rock
Point B - Extrusive igneous rock
Explanation:
Intrusive igneous rocks are rocks which is formed by molten magma that cools and solidifies below and within the surface of the earth, thereby forming large crystals beneath the earth surface. Examples of Instrusive igneous rocks gabbro, granite, peridotite etc.
Intrusive Ignoeus rock is formed at point A in the diagram given above.
Extrusive Ignoeus rock, on the other hand, is the opposite of Intrusive igneous rock. Extrusive igneous rock is formed when molten rocks, called magma, erupts from beneath the earth and cools and solidifies on the surface of the earth, thereby forming small crystallized rocks. Examples of extrusive igneous rocks are basalt, pumice, etc.
Extrusive Ignoeus rocks would formed at point B in the diagram above.
Answer:
D
Explanation:
Water and air circulate around the world in water currents and wind systems (like prevailing winds) respectively, hence distribute energy and whatever else they are carrying across the globe. This is why polluting the oceans in the equatorial region will have indirect consequences for marine life in the poles.
Pollution of air through emission of greenhouse gases in one part of the globe will contribute to global warming across the world because these emissions will be carried around by prevailing winds and diffuse across the atmosphere.
Global warming also causes climate change that subsequently causes the displacement or migration of organisms when this change in climate is unfavorable
