What is the probability that a seed from a parent plant of genotype Rr will carry the r gene
daser333 [38]
The answer is 50 percent.

Parent plant of genotype Rr will in meiosis produce haploid gametes which will carry either R allele or r allele. Since there are only two possibilities R or r, the probability that seed will get r gene is 1 of 2. This can be presented as 1/2, which is 50%.

Describe some of the factors that have contributed to the success of seed plants
SpyIntel [72]
Heterospory, highly reduced gametophytes, ovules, pollen, seeds are the five adaptations common to all seed plants that ensure their success in the adaptation to land. Three things: The gametophytes of seed plants are reduced and dependent upon the parent sporophyte which protects them (particularly in the case of the female gametophyte). Pollen is covered with sporopollenin which is resistant to physical factors in the environment. The structure of the seed protects the next generation sporophyte and allows it to remain dormant until conditions are right for germination, development and growth.

Why is nonpoint surface pollution is a greater threat and hazard than point source pollution

Nonpoint source pollution is a greater hazard, because scientists are not able to identify a single location the pollution came from. It is harder to find a solution if they are unable to find the source.

Hope this helps!

The organelle identified in the picture as #10 helps the cell maintain homeostasis in what way? This organelle is the smaller wh

Microtubule – serves as a framework of the cell –cytoskeleton.<span>

Nucleus – the control center of each cell. It regulates, monitors and organizes the whole cell<span>

Since the pictures isn't given I can assume that it can be the microtubule, the microtubule is responsible for maintaing the shape and structure of the overall cell. It maintains homeostasis by permanently aiding the framework of the overall cell.
If it is the nucleus, the control center of a cell. It does a lot of functions in the cell, it helps maintain homeostasis by sending commands that the organelles do, supply energy, excrete or digest waste, regulate the movement of objects and cellular respiration, even cell division. It sustains the cell to be functional and proactive at the same time reactive to situations that is likely to occur.
