History of life documented by fossils
Answer:
5.1 billion metric tons of carbon is emitted by U.S as compared to other countries which emits about 32.5 billion metric tons of carbon.
Explanation:
U.S emits about 5.1 billion metric tons of carbon in the atmosphere which contribute in air pollution also helps in rising the temperature of the earth atmosphere because carbondioxide is a green house gas which increases the earth temperature. The main reason of high amount of carbon emission is the high number of industries and more fossil fuels is burnt in the engines of vehicles.
The right options are; makes food for all organisms, adds oxygen to the atmosphere, is a source of medicines and fibers, is a source of building materials and it provides animal habitat.
Photosynthesis is a process by which green plants and some other autotrophs use light energy in chloroplasts to generate carbohydrates (food) from carbon dioxide and water while oxygen is being released as a by-product. Photosynthesis is essential to all living organisms on earth because it is the main source of oxygen in the atmosphere. Photosynthesis provides animal habitat, it provides food for all organisms (directly for plants and indirectly for animals). Plants and trees produce their foods through photosynthesis and are used as medicines and fibers, and as building materials.
The answer is to this question is A
Answer:
Phenotype genotype Number of individuals
Red RR 245
Pink Rr 210
White rr 45
Number of alleles in total
R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency
r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency
Predict (Hardy Weinberg) genotype frequencies=
p^2 + 2pq + q^2 = 1
p= 0.7
q=0.3
0.49 + 0.42 + 0.9 =1
According Punnett Squares in F1 we have=
Rr* rr = Rr 50% and rr 50%
