Question

22 multiple answer 2 points which of the following contain nitrogen? (choose all that apply) lipids nucleic acids proteins carbohydrates 23 multiple choice 2 points as the population density of rabbits in a field increases, competition for food intensifies. what is a likely outcome of this increased competition if it is considered a density - dependent limiting factor? individual rabbits may have reduced growth rates or reproductive rates due to insufficient food. the rabbit population will continue to grow exponentially because of the abundance of food. the increased competition for food will have no impact on the rabbit population as other resources are abundant. predators of rabbits will decrease in number due to the increased competition among the rabbits. 24 multiple choice 2 points species which are introduced by humans to new habitats and disrupt the food web in that ecosystem is called a(n) species. predator new invasive companion

Explanation:

• For question 22: Lipids mainly consist of carbon, hydrogen, and oxygen. Nucleic acids have nitrogen - containing bases. Proteins have nitrogen in their amino - acid structure. Carbohydrates are composed of carbon, hydrogen, and oxygen only.
• For question 23: In a density - dependent limiting factor situation like food competition in rabbit population, lack of food will lead to reduced growth and reproductive rates. Exponential growth is not possible with food limitation. Abundant other resources won't nullify food competition's impact. Predator numbers are not directly decreased by rabbit - to - rabbit food competition.
• For question 24: Species introduced by humans to new habitats and disrupting the food web are called invasive species. Predators are not defined by human - introduced disruption. "New" is too general. Companion species do not disrupt food webs.

Answer:

1. nucleic acids, proteins
2. Individual rabbits may have reduced growth rates or reproductive rates due to insufficient food.
3. invasive
