To observe how plants compete for space, seeds were tested in an experiment. The same amount of soil was put into each of five plastic cups. Two seeds were planted in the first cup, 4 seeds were planted in the second cup, 8 seeds in the third cup, and 16 seeds were planted in the fourth cup. Only one seed was planted in the last cup to compare with the other pots. After 25 days, the height of the plants was measured to determine which plants grew best. what is the control of this experiment

What would happen to the nutrients in an ecosystem if decomposers, such as bacteria, didn’t exist there?

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?

What noticeable trend from this graph might be used to make a conclusion?
