Active transport require the cell to expand energy whilst Passive transport require no energy from the cell in active transport.
Passive Transport moves molecules across membrane without the use of energy by the cell.
-Simple diffusion
-Facilitated diffusion
-Osmosis
Active Transport uses energy (ATP) to move molecules across membrane.
-Protein pumps
-Exocytosis
-Endocytosis (Phagocytosis & Pinocytosis)
I think B but I maybe wrong please correct
Answer:
4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.
Explanation:
Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.
Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.
The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).
RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes
RRtt, Rrtt -> Red petals with short bushes
rrTt, rrTT -> pink petals and tall bushes
rrtt-> pink petals with short bushes.
These are the four phenotype variations possible in this dihybrid cross.
Answer:
This question is incomplete but the completed question is below
eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?
(a)The roots change into branches, and the branches turn into roots.
(b)The roots grow toward the force of gravity, and the shoots grow away.
(c)The plant will become a smaller version of a mature plant.
(d)Roots always grow toward the dark, and shoots grow toward the light.
Two options appear to be correct here: options B and D
Explanation:
Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b
