Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.
FRONTAL LOBE are involved in that.....
Answer:
Competition will occur between organisms in an ecosystem when their niches overlap, they both try to use the same resource and the resource is in short supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.
A eukaryotic cell that is involved in synthesizing large amounts of protein might be expected to have a lot of ribosomes. Ribosomes are dot like structure that are located around the rough endoplasmic reticulum. They are where proteins are made. There are also a few that are located in the cytoplasm. These ribosomes are the ones that give the endoplasmic reticulum a rough edge.
Natural selection doesn't favor traits that are somehow inherently superior. Instead, it favors traits that are beneficial (that is, help an organism survive and reproduce more effectively than its peers) in a specific environment. Traits that are helpful in one environment might actually be harmful in another.
(one again, I hope this helps ^^)
