Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.
Answer:
159.808 g/mol
Explanation:
Br itself is 79.904 g/mol. So multiply it by two.
Answer: c. Air pollution
Explanation:
There was a heatwave in Europe during the early years of the 21st century that killed tens of thousands across the continent and thousands in France.
Air pollution was blamed for having made the situation worse because the pollutants in the air acted to prevent heat from escaping back into the atmosphere which led to increased heat on ground and therefore a heat wave.
<span>Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So, in general, if you cut 500 calories from your typical diet each day, you'd lose about 1 pound a week (500 calories x 7 days = 3,500 calories).

Answer:
BB - Dark brown color - (1/4)
Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)
bb - white color - (1/4)
Explanation:
Let the allele for dark brown pigment be represented by "B"
And the let allele for white (no pigment) be represented by "b"
Due to incomplete dominance, the phenotype of heterozygous species would be "light tan"
Genotype of heterozygous female - Bb
Genotype of heterozygous male - Bb
Bb * Bb
BB, Bb, Bb, bb
BB - Dark brown color - (1/4)
Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)
bb - white color - (1/4)
