In terms of density, the oceanic crust is denser than continental crust, which also means it is heavier.Density is important in the formation of layers on Earth. Because continental crust is less dense, it floats higher than oceanic crust. If the two will have different densities, then continents will be submerged in the ocean.
According to Mendel's experiment if we construct a punnet square the expected ratios should be 9:3:3:1. From our experimental results,
purple smooth = 75 ( 0.56) the expected is 0.56
white smooth = 28 ( 0.21) expected is 0.19
purple wrinkled= 24 (0.18) expected is 0.19
white wrinkled = 8 (0.06) expected is 0.06
From this results we plug the observable and expected values in a chi-square which is used to account for the differences between the expected and observable values. Then we conclude that the deviation of the observable value from the expected value is probably due to random sampling error and therefore we accept the hypothesis, such that the results are in consistent with the law of assortment.
Answer:
The neuro cognitive disorder of blood flow to the brain is called as dementia.
Explanation:
When mental function decreases due to mental diseases,the term is called dementia in medical terminology.
There are several causes of dementia are-
- Brain injury which is caused by trauma.
- Intra cerebral hemorrhage,blood clot in the brain
- Breathing problem like hypoxia.
- Cardiovascular problems like TIA, Stroke,heart infection etc.
- Alzheimer disease,Huntington disease,HIV,any injury in brain.
- Pick disease etc
Answer:
The preferable words for the fill in the blanks will be -
Aragonite, calcite
Explanation:
- Biogenic minerals are minerals produced by living organisms. Two commonly seen biogenic minerals are <u>aragonite</u>, which is often produced by coral and other invertebrates, and <u>calcite</u>, which often makes up the shell material of mollusks such as clams.
- Biogenic minerals are the mineral substances that are produced by geologic processes. For living organisms, it is their most commonly produced byproduct.
- E.g; vertebral bones, shells of Oyster, mussel, and clam (aragonite), etc.
