Answer:
Facilitated Diffusion
Explanation:
Some molecules can move down their concentration gradients by crossing to the lipid portion of the membrane directly,while others must pass through membrane protein s in a process called Facilitated Diffusion
Examples of lipids include fat boils wags his hormones and steroids. Lipid or non-polar molecules so they are not soluble in polar like water.
Double fertilization-plants with seeds (flowering plants), two male gametes joining with female gametophyte
Gametophyte generation-both (haploid, sexual stage stage-gametophyte, and the diploid stage that produces spores – sporophyte)
Endosperm formed-plants with seed because it is a tissue formed inside the seed which surrounds the embryo and provides nutrition
Mitosis-both (mitosis occurres in spores)
Spores develop into gametophytes-both but, in seedless plants sporophyte produces spores that will develop into a new organism (multicellular gametophyte) using mitosis, while spores of seed plants are produced internally and develop into more complex structures.
Answer:
Explanation:
A gray squirrel can either have the same alllele GG or have two different allele Gg this will determine the percentage of the offspring that will be Grey.
For 2 parent with same allele
GG × GG
!
GG GG GG GG
all are grey 100%
For 2 parents with different allele
Gg × Gg
!
GG Gg Gg gg
75% will be grey
25% other color
Answer: Evolution
Explanation:
Evolution can be defined as the change in the characteristics of the species over a period of time which basically relies on the process of the natural selection.
The characters that allows the survival of the organism is favored and is known as the survival of fittest which is a natural selection.
This is known as evolution in which the herbicide resistant plant is favored more and has developed over a period of time.
