Answer:
1500
Explanation:
Let's assume that the allele for yellow seed color is "Y" and the allele for green seed color is "y". Genotype of pure breeding yellow seeded plant would be "YY" and that of the green seeded plant would be "yy". A cross between YY and yy gives all heterozygous yellow seeded plants (Yy) in F1 progeny. Self pollination of two F1 plants (Yy x Yy) obtains F2 generation in 3 yellow: 1 green ratio.
The total population size of F2 generation = 2000
The proportion of yellow seeded plants in F2 generation = 3/4 (since the F2 phenotype ratio is given 3 yellow: 1 green)
Therefore, total number of yellow seeded plants in F2 progeny = 3/4 x 2000= 1500
D) relieving fishing pressure on over fished species
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
because malnutrition causes various health issues and diseases, lowers your immune system, and causes death.
The answer is : Light waves would be more likely to be refracted or diffracted, thus failing to reach plants and phytoplankton
Sunlight is needed by the producer(plants, phytoplankton) in the ocean to do photosynthesis. When an are is attacked by severe storm, the area will be covered by cloud of the storm which impede the light, cause it to be refracted or diffracted. This will cause less light comes to the producer of the plants and phytoplankton.
