Answer:
answer is d
Explanation:
THe answer is D because this is dihybrid cross and we cross bwbw RR( normal red eye gene) x RR cncn. The F1 progeny has R in all locus of these genes so all will be R as heterozygous. When F1 progeny crossed, the 1/4 of bw cross and 1/4 of cn cross habe bwbw/cncn and will be white. So it will be 1/4x1/4 = 1/16
Answer:
C
Explanation:
Acidic soils mean they have more of Al3+ and H+ ions which are acid forming cations. These cations make alkaline forming ions unavailable to plants as nutrients. When the pH of the soil is raised, the Al3+, Fe3+, and H+ are neutralized. The ions bind with –OH ions hence releasing the ions in the negatively-charged sites on the hummus to play a role in the nutrient exchange.
Answer:
1. The cell splits itself twice
2. 4 resulting sperm cells are made
3. Only half of the DNA is kept per cell
Explanation:
Mitosis only has one diving phase that occurs only on body cells, which makes it have 2 daughter cells. This, on the other hand, has 4 daughter cells. If you notice, after the third set of bubbles, the genome(DNA) is split among 4 cells.
96 kelvin = about -177 Celsius so A
