Answer:
1. 2 alleles, solid brown and spotted
2. 1 dominant, spotted, and one recessive, solid
3. Dominant: 16/24 Recessive: 8/24. Spotted- R, solid, r. There are 6 RR, 4 Rr and 2 rr.
4. It would slowly become more common and common. When a spotted and a solid pairs, its still most likely that the offspring will be spotted, however as most spotted die the number of spotted getting offsprings decrease.
5. No genetic variation, everyone in the population has that trait
The answer is; C
Rhizoids are analogous to roots in vascular plants. They anchor the gametophyte of the moss into the substrate. The rhizoid is also significant in absorbing nutrient from the substrate just like roots. While roots of vascular plants are multicellular, rhizoids may be unicellular or multicellular. Unlike in roots where water is absorbed and passes through the roots up the plant, in rhizoids, water is carried by capillary action in between the rhizoid threads.
All of the work being done in side of a cell is being done by enzymes. A bacterial like E.coli has about 1,000 enzymes floating in the cytoplasm at about any time. The purpose of a enzyme in a cell is to allow the cell to carry out any chemical reactions very quickly. the reactions allow the cell to build or take things apart as needed. This is how the cell grows and reproduces. Hopefully my answer helps a little!
The answer to this question would be a
