1,000x2=2,000
2,000x2=4,000
4,000x2=8,000
8,000x2=16,000
Answer: 16,000
The correct answer is: A) The polarity of membrane phospholipids
Factors that affect membrane permeability are
1. Chemicals :
Some of the organic solvents such as chloroform and ethanol can dissolve the membrane and thus, destroy the selective permeability of the membrane.
2. Temperature :
Too high temperatures denature the protein that are in the structure of the membrane destroying its selective permeability. On the other hand, too low temperature slows down molecule movements and the permeability decreases.
3. Cholesterol:
Increases the permeability by reducing the barrier formed by phospholipids’ heads
4. The saturation of hydrocarbon tails in membrane phospholipids:
Saturated fatty acids decrease permeability of the membrane because they get very close together, which makes it harder for the molecules to pass through.
Answer:
a. (black fur): phenotype
b. (AA, Aa, aa): genotypes
c. (Aa): heterozygous
d. (aa): hom0zygous recessive
e. (AA): hom0zygous dominant
Explanation:
(lol brainly wont let me some of the words)
I took bio and genetics I hope this helps !!!
6 protons is the amount of electrons so it would be... 6 protons 6 neutrons 6 electrons in all so it is probably 18 protons but im not to sure but..idk good luck
The answer is <span>insect and pest populations decreased.
</span>
DDT (dichlorodiphenyltrichloroethane) was used as an insecticide which is a substance used to kill insects. That resulted in decrease in insect and pest populations. It is a persistent and non-degradable insecticide, but as well organic pollutant readily accumulated to soils and consequently affects organisms.
