Linda is studying the interaction between porcupines, pinion pine trees, and pine bark beetles. over the course of her study in northern texas, she observes the behaviors of 25 porcupines, records the location of 151 pinion pines, and traps 332 beetles. her study encompasses population(s) and organisms. a. 1; 508 b. 3: 3 c. 508; 508 d. 3; 508 e. 508; 3

D. 3; 508

Explanation:

A population compromises of the number of organisms of same species which can interbreed living in a particular geographical area. These members can interbreed to reproduce fertile offspring. A population can occur both in small and large areas.

Here, Linda observed three different populations: porcupines, pinion pines and beetles. The total organisms in her study comes from adding all the organisms from the three different populations. Thus, total organisms she studied is:

25 + 151 + 332 = 508.

Hence, Linda's study encompasses 3 populations and 508 organisms.

i do not know and i have a 100 in this class

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
