Climate change represents a negative impact of technology. Technology can release harmful pollutants into the air such as greenhouse gases that cause climate change.
Answer:
Cooler conditions eliminated many warm water species, and glaciation lowered global sea level. However, during the Cambrian there was no significant ice formation. None of the continents were located at the poles so land temperatures remained mild.
Explanation:
The answer is 0.43
To calculate p we will use one of two formulas of the Hardy-Weinberg principle:
p² + 2pq + q² = 1 and p
+ q = 1
where:
p - the frequency of the allele for long legs which is a dominant trait.
q - the frequency of the allele for short legs which is a recessive trait.
p² - the frequency of dominant homozygote (with long legs)
2pq - the frequency of heterozygote (with long legs)
q² - the frequency of recessive homozygote (with short legs)
So, 33 of 100 organisms have short legs. The frequency of recessive homozygote is represented by q²:
q² = 33/100 = 0.33
⇒ q = √0.33 = 0.57
Using the formula:
p + q = 1
p = 1 - q = 1 - 0.57 = 0.43
Therefore, p = 0.43
Answer: Option D
Explanation:
Apolipoprotein B is a type of apolipoprotein that bind lipids including cholesterol and forming the main organizing protein in lipoproteins such as in the low density lipoprotein. The low density lipoprotein serves as a vehicle to transport cholesterol into the cell through the receptor mediated endocytosis process. This process allows for the movement of larger molecules from the outside of the cell into the cell. Thus apolipoprotein can bind as ligands to the LDL receptors and allow for the transport of fats into the cell..
