Concept 1 -Introduction to Ecology Notes Review

During a field trip to a local forest, Ava, Zoe, and Avery observed various interactions between plants, animals, and their surroundings. What were they studying?

• The study of human behavior

• The study of relationships between organisms and their environment

• The study of geological formations

• The study of historical events

What role does the study of organisms play in enhancing our ecological conservation efforts?

• To improve genetic engineering techniques

• To better predict climate change impacts

• To enhance strategies for biodiversity conservation

• To develop new computational models for ecosystems

During a biology project, Ava researches the simplest forms of life. What can be the minimum number of cells that living organisms are composed of?

• Two

• Multicellular

• One (unicellular)

• None

During a science fair, Priya presents a project on the molecules responsible for heredity and genetic information in living organisms. Which of the following can be a genetic material?

• Proteins

• Lipids

• DNA or RNA

• Carbohydrates

What is one of the characteristics of life according to the provided material?

• Ability to shrink

• Capability of growth

• Ability to remain static

• Capability of flying

How many parents are involved in sexual reproduction ?

• 1

• 2

• 3

• 4

What type of offspring results from asexual reproduction?

• Genetically unique offspring

• Genetically identical offspring

• Offspring with mutations

• Offspring of different species

What is the primary function of the sperm and egg in sexual reproduction?

• To provide nutrition to the offspring

• To combine genetic material and form a new organism

• To divide and form multiple cells

• To migrate to different parts of the body

What is a stimulus in the context of the characteristics of life?

• How an organism reacts to a change in its environment

• A change in an organism's environment

• The direction in which sunflowers grow

• The ability to respond to outside stimuli

Answer explanation

A stimulus in the context of the characteristics of life refers to a change in an organism's environment, which triggers a response or reaction from the organism.

What does the term 'response' refer to in the characteristics of life?

• The direction in which sunflowers grow

• A change in an organism's environment

• The ability to respond to outside stimuli

• How an organism reacts to a change in its environment
