I’m pretty sure number 1? I’m not sure though sorry
Answer: Option D is the correct answer.
Explanation:
Animals are not the first to colonize land. Prokaryote are probable the first organisms to colonize land. They have been existing about 2.6 billions years ago. Fungi have been in existence long time ago. Study reveals that they have been living in aquatic habitat before coming to colonize the land.
I feel the producers are the most important, because if they collapse, soon the plant eaters will collapse, then the animals that eat them, and so on.
You could also say A scavenger is the most imporant because without them we wouldnt be ŕecycling´ food.
Answer: If the F2 occurs in the ratio 9 blue:3 pink:4 white, one gene pair (i.e 2 genes) control the flower color phenotype.
Explanation: This principle is called INCOMPLETE DOMINANCE where one gene (dominant) won't completely override the other (recessive).
Let assume B represents the dominant gene and b represents the reccesive gene. Let also assume that Blue color is dominant over white color. We can assign the genotype as follows;
Homozygous dominant genes BB will produce Blue color
Homozygous recessive genes bb will produce white color
Heterozygous genes Bb will produce pink color.
Therefore, a pair of gene ( 2 genes) will determine the flower color phenotype.
Homeostasis is the property of either an open system or a closed system, especially a living organism, that regulates its internal environment so as to maintain a stable, constant condition. The bigger the body size, the harder it has to work.
