Answer:
Yes, smoking (or chewing) tobacco can make people aggressive. First, while smoking and just after finishing smoking , people report feeling "good". That is, smoking gives them a sense of pleasure.

Answer:
6 giraffes
Explanation:
If an area can provide 450 pounds of food for the giraffes and the giraffes eat 75 pounds of food per day, you can divide:
450 by 75= 6
6 giraffes is the capacity for that area
This backbone is composed of alternatingsugar and phosphate groups, and defines directionality of the molecule. Thesebonds are called phosphodiester bonds, and the sugar-phosphate backbone is described as extending, or growing, in the 5' to 3' direction when the molecule is synthesized.
Answer:
It is necessary.
Explanation:
If a member of a species doesn't reproduce, other members of the same species will become extinct.
Answer:
<u><em>Endocytosis</em></u>
Explanation:
Facilitated diffusion just means that a channel/carrier protein facilitates the transport of the molecule. It goes along the concentration gradient.
Diffusion is simple passive transport/simple diffusion. Only small nonpolar molecules can do this.
<u><em>Endocytosis is a type of bulk transport. It is when macromolecules are brought into the cell. This is a type of active transport because it requires energy to do.</em></u>
Osmosis is specifically used for water, and water is a small, nonpolar molecule. In a phospholipid bilayer/cell membrane, aquaporins (a protein) are used to facilitate transport across the membrane. Fun fact: Reverse osmosis is used to desalinate salt water. They basically push water through a man-made membrane that will only allow water to pass through.
Overall, passive transport is along the concentration gradient, while active is against it (going along the concentration gradient means if there is more of one molecule on one side of a membrane than the other, the molecule on the higher side will go towards the lower side)
I learned this in respect to a phospholipid bilayer. If you need a further explanation on any of this lmk.
