Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes

Answer:
1) start as a carbon molecule in the atmosphere
2) taken in by trees through photosynthesis
3) carbon is taken into decayed organism
4) then it is taken into dead organisms and waste products underground
5) millions of years later, it is stored in a fossil
6) fossil fuels used by factories then emit carbon dioxide back into the atmosphere (back to starting position
if you want the whole cycle then..
7) used again by a tree
8) released as organic carbon (some)
9) tree leaf is eaten by an animal, which then releases carbon either from respiration or when it dies
Answer:
b. Foraging birds eat left over rice and trample the ground making trilling unnecessary.
Explanation:
The California ricelands Habitat Partnership is a partnership between rice farmer and conservation group that will promote long term sustainability of wetland species.
This farming method is beneficial to both the farmers and the species. The wetland species such as foraging birds will benefit by coming to eat the left over rice after the farmers have harvested the rice.
As the birds eat the rice, they trample the grounds making trilling unnecessary hence benefiting the rice farmers.
Answer:
a. The formula for finding the number of colonies in a given volume is,
CFU/ml, here CFU is the colony forming units or the number of colonies formed in a volume plated in ml × dilution
The dilution factor given in the question is 1 × 10⁻⁴ and the number of colonies given is 186. Therefore, the number of bacteria present in the given 1 ml of the milk is,
CFU/ ml = 186 / 1 × 10⁻⁴ = 186 × 10⁴.
Hence, the concentration of bacteria in the milk is 186 × 10⁴ CFU/ml.
b) The limit of the bacterial concentration in the pasteurized milk is 20000 CFU/ml, however, it can be seen that the sample of the milk possess more concentration of bacteria than the desired value. Therefore, the milk is not safe to drink by Public Health Standards.
