Its b during how ever you say that word if not that then c not all the way sure tho
It helps you to think through your problems. It also allows you to figure out equations. Etc.....
Hope this helps
Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
Answer:
1/3
Explanation:
<em>A standard monohybrid cross is a cross that follows the dominance/recessive pattern from Mendel's experiment.</em>
It means the purple flower color is dominant over the white flower color.
Assuming the allele for purple flower color is P and that of the white flower color is p, a standard monohybrid cross will involve a true breeding PP and pp.
PP x pp: Pp, Pp, Pp and Pp. All the F1 offspring will have purple flowers with Pp genotype.
At F2: Pp x Pp = PP, Pp, Pp, and pp.
3/4 or 75% of the F2 offspring have purple flower color out of which 1 is true breeding for the trait.
Hence the fraction of the purple flowered peas in the F2 that is expected to be true-breeding (PP) is 1 out of 3.
