1. How are the life cycles of a bird and an insect the same?
Correct Answer
B. Both start out as an egg and grow and change until they can lay eggs of their own.
Explanation
The correct answer is that both birds and insects start out as an egg and go through a process of growth and change until they are able to lay eggs of their own. This is known as metamorphosis, which is a common characteristic of both bird and insect life cycles.

What would happen to baby robins if their parents did not care for them?
Correct Answer
C. They would not survive alone becaue they cannot stand up, see, fly , or feed themselves.
Explanation
If baby robins were not cared for by their parents, they would not survive because they are unable to stand up, see, fly, or feed themselves. This implies that they are completely dependent on their parents for their basic needs and without their care, they would not be able to survive on their own.

How can animals that do not hibernate survive the cold?
Correct Answer
E. All of the above.
Explanation
Animals that do not hibernate can survive the cold by using various strategies. Migration to warmer places allows them to escape the harsh winter conditions. Storing food for winter ensures a constant food supply when resources are scarce. Growing thicker fur provides insulation and helps retain body heat. Eating lots and gaining an extra layer of fat also helps in keeping warm during the cold months. Therefore, all of the mentioned options are valid ways for animals to survive the cold.
4.
When winter arrives in the animal kingdom, warmth and food become hard to find. What are the two things that animals do to survive at this time?
Correct Answer(s)
A. Hibernation
C. Store food
Explanation
During winter, animals face challenges in finding warmth and food. To survive, some animals hibernate, which means they go into a deep sleep-like state to conserve energy. This allows them to survive with limited food resources. Additionally, animals also store food during the fall to have a sufficient supply throughout the winter when food is scarce. Therefore, the two things that animals do to survive during winter are hibernation and storing food.
5.
What do all animals need to survive?
Correct Answer(s)
A. Food
B. Shelter
C. Oxygen
Explanation
All animals need food, shelter, and oxygen to survive. Food provides the necessary nutrients and energy for their bodies to function properly. Shelter protects them from harsh weather conditions, predators, and provides a safe place to rest and sleep. Oxygen is essential for respiration, the process by which animals obtain energy from food. Without oxygen, animals cannot survive. Reproduction is important for the continuation of the species, but it is not necessary for an individual animal's survival. Urination is a bodily function that helps eliminate waste products, but it is not a requirement for survival.
6.
Is a cow's life cycle the same as or different from a frog's life cycle?
Correct Answer
E. All of the above.
Explanation
The correct answer is "all of the above" because both a cow's life cycle and a frog's life cycle begin as eggs, change and grow as they get older, have babies, and eventually die. Additionally, a frog undergoes a specific transformation from living in water to being able to live on land, which is a unique aspect of its life cycle compared to a cow.
7.
Why do some animals grow up faster than other animals? Give 2 reasons.
8.
What happens to animals that hibernate?
Correct Answer
A. Their body temperature drops
Explanation
During hibernation, animals undergo a state of reduced metabolic activity to conserve energy. As a result, their body temperature drops significantly. This drop in body temperature helps to slow down their heart rate, breathing, and other bodily functions, allowing them to survive with minimal energy expenditure during the winter months. By lowering their body temperature, animals can conserve energy and survive without the need to actively search for food or maintain their usual level of activity.
9.
All animals need _______________ to survive because it gives them the energy to keep all parts of their body working.
Correct Answer
A. Sunlight and food
Explanation
Sunlight and food are essential for animals to survive. Sunlight provides energy through the process of photosynthesis, which is the primary source of energy for plants. Animals obtain this energy by consuming plants or other animals. Food, on the other hand, provides the necessary nutrients and building blocks for the body to function properly. Together, sunlight and food ensure that animals have the energy to fuel their bodily functions and maintain their overall health and well-being.
10.
What kinds of changes do not come from growth?
Correct Answer
E. All of the above
Explanation
All of the mentioned changes (reproduction for females, illness, aging, and learning) do not come from growth. Growth refers to the increase in size or development of an organism, while these changes are separate processes that can occur regardless of growth. Reproduction for females is a natural process that allows for the creation of new individuals, illness is a result of external factors such as pathogens, aging is a natural biological process that occurs over time, and learning is a cognitive process that involves acquiring knowledge or skills. None of these changes are directly linked to growth.
11.
Which of the following is not essential for good health?
Correct Answer
D. Stress
Explanation
Stress is not essential for good health. While exercise, sleep, and keeping clean are all important factors for maintaining good health, stress can have negative effects on both physical and mental well-being. High levels of stress can lead to various health issues such as cardiovascular problems, weakened immune system, and mental health disorders. Therefore, reducing and managing stress is crucial for overall good health.
