PLEASE HELP and explain The claim that a certain species of plants produce ammonia in their roots to counteract the negative effects of acidic soil would be supported by which of the following observations?T
he frequency in the population of individual plants that produce high levels of ammonia in their roots increases with soil acidity.
As the acidity of the soil increases, the number of individual plants able to survive and reproduce decreases.
When the plants are grown in soil with a neutral pH, the levels of ammonia in the roots of the plants remains stable over generations.
When plants that produce high levels of ammonia are crossed with plants that produce low levels, the offspring survive.

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.

Graphs you see question 5 options: the change in data over time the relationship between different dependent variables the relationship between the independent variable and the dependent variable/s the relationship between different independent variables

Why is the theory of evolution important? it disproves all other theories about how life began. it provides a topic for debate. it is a unifying concept in biology. it explains how life began. i know for sure, it is not "it is a unifying concept in biology."
