Answer:
Polygenic traits are quantitative because their phenotype expression depends on several different alleles found on different chromosomes.
Explanation:
ON EDGE
Answer:
F. Both regulation and secretion
Explanation:
Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.
Answer:
Order the steps to take when drawing electron dot diagrams.
Count the dots to make sure that all of the valence electrons are represented.
✔ 4
Draw dots around the chemical symbol to represent the valence electrons of the atom.
✔ 3
Use the periodic table to find the chemical symbol of the atom and the number of electrons in the valence shell.
✔ 1
Write the chemical symbol of the atom.
✔ 2
Explanation:
I did it on Egde I guess on the answers BTW just to help you guys
<em>here is the answer ,, you can make a decay curve like this example..</em>
The correct answer is B.
Genetic drift is one of the four evolutionary mechanisms. It changes the frequency by chance, aka at random.
For example. if you have 100 frogs in the population, 20 red, 20 green and 60 yellow, not all of the alleles are going to be passed down to the next generation because a portion of the population can be affected by a random event such as the flood. So, if the flood accidentally kills 20 red frogs, none of the offspring are going to be red by chance.
