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.
Answer:
B
Explanation:
Meiosis produces gametes that contain one complete haploid set of chromosomes
Meiosis is a reduction division, where the number of chromosomes in the daughter cells is reduced to half as compared to the parent cell. This set of chromosomes is called a haploid set or genome. The reduction from diploid to haploid occurs during Anaphase I of meiosis I, where homologous chromosomes separate and enter into two different cells. Meiosis takes place only in reproductive cells that divide to form gametes
So, the correct answer is 'Meiosis produces gametes that contain one complete haploid set of chromosomes'
hope that helps
