Science & Health Final Exam Quarter 2

An interact is to help each other.

When we breathe in, we inhale air into our lungs, and when we breathe out, we exhale air from our lungs. The lungs are the organs responsible for the exchange of oxygen and carbon dioxide between the air and our bloodstream. They play a crucial role in the process of respiration, allowing us to take in oxygen and release carbon dioxide. Therefore, the correct answer to the question is "lungs."

In Marshallese language, the word "deka" is used to refer to the kidney.

An ecosystem is a term used to describe communities of living things in a specific area. It refers to the interactions between organisms and their physical environment, including the biotic (living) and abiotic (non-living) factors. These interactions play a crucial role in maintaining the balance and functioning of the ecosystem.

The excretory system is responsible for eliminating waste products from the body. This system includes various organs such as the skin, lungs, and kidneys. The kidneys play a crucial role in filtering the blood and removing waste products, excess water, and toxins from the body. Therefore, from the excretory system, we learn about the importance and functions of the kidneys in maintaining the body's internal balance and eliminating waste.

The correct answer is animals and plants. Biotic factors refer to the living components of an ecosystem. Animals and plants are both living organisms and play crucial roles in the functioning of ecosystems. Animals interact with plants through processes like pollination and seed dispersal, while plants provide food and habitat for animals. Together, animals and plants form a complex web of interactions that contribute to the overall balance and health of an ecosystem.

The correct answer is "no" because it is important to stand up against unethical behavior such as stealing. By saying "no," you are asserting your integrity and refusing to participate in illegal activities. It is crucial to prioritize honesty and respect for others' property, even if someone is pressuring you to do otherwise.

It is not advisable to always say yes when someone pressures you to drink alcohol. This answer is correct because it is important to prioritize your own well-being and make decisions that align with your personal values and beliefs. It is okay to say no to drinking alcohol if you do not want to or if it goes against your principles. It is crucial to assert your own boundaries and make choices that are right for you, rather than succumbing to peer pressure.

"Learn Draw the Line and Respect the Line" is a program that provides education and information about HIV, STDs, and pregnancy prevention. By participating in this program, individuals can gain knowledge about safe practices and make informed decisions to protect themselves from these risks. Therefore, it is reasonable to conclude that this program can indeed help prevent HIV, STDs, and pregnancy, making the statement true.

The statement implies that pregnancy is not advisable for 12-year-old girls. This is because their bodies are not fully developed and they may face serious physical and emotional health risks. Pregnancy at such a young age can also hinder their education and future opportunities. Therefore, agreeing with the statement suggests understanding the potential negative consequences and advocating for the well-being of young girls.

Birds cannot live underground as they are adapted for flying and living in trees or on the ground. They build nests in trees, cliffs, or on the ground, but they do not inhabit underground burrows like some mammals do. Birds require open spaces for flight and access to the air for breathing. Therefore, the statement that birds can be habitat in live underground is false.

The correct answer is "community." A community refers to a group of different populations of organisms that live and interact with each other in the same geographical area. It consists of various species, each with its own population size and dynamics. Therefore, a community is the most appropriate term to describe all populations in different species within a given area.

The given statement is true. When a living thing dies, it undergoes decomposition. During this process, the organic matter in the body breaks down, releasing nutrients into the environment. These nutrients can then be utilized by decomposers, such as bacteria and fungi, to grow and reproduce. Insects, such as flies and beetles, are often attracted to the decaying organic matter and lay their eggs on it. These eggs hatch into larvae, which feed on the decomposing matter. Therefore, the death of living things can indeed create small insects from a mixture of non-living matter.

The statement is false because biotic and abiotic factors do interact with each other in an ecosystem. Biotic factors refer to living organisms such as plants, animals, and microorganisms, while abiotic factors refer to non-living components like temperature, sunlight, water, and soil. These factors interact and influence each other's presence, distribution, and behavior. For example, plants require sunlight (abiotic factor) for photosynthesis, and animals depend on plants for food (biotic factor). Additionally, changes in abiotic factors like temperature can affect the behavior and distribution of organisms. Therefore, biotic and abiotic factors are interconnected and interact in an ecosystem.

The correct answer is 5 because abiotic factors refer to non-living components of an ecosystem that can influence living organisms. These factors include temperature, sunlight, water availability, soil composition, and air quality. Therefore, there are five main categories of abiotic factors, making option 1 the correct answer.

The correct answer is 4 because physical fitness is generally divided into four main components: cardiovascular endurance, muscular strength, muscular endurance, and flexibility. These four components encompass different aspects of physical health and fitness, including the ability to perform aerobic activities for an extended period, the strength of muscles to perform tasks, the ability of muscles to sustain repetitive movements, and the range of motion of joints and muscles. By focusing on these four components, individuals can improve their overall physical fitness and achieve a well-rounded level of health.

Climate refers to the average weather conditions of an area over a long period of time, typically 30 years or more. It includes factors such as temperature, precipitation, humidity, wind patterns, and other atmospheric conditions. Climate is an important factor in determining the type of vegetation, wildlife, and overall ecosystem of an area. It is different from weather, which refers to the short-term and day-to-day variations in atmospheric conditions.

The biosphere refers to the part of Earth that supports life. It includes all living organisms and their interactions with the environment. This includes the atmosphere, hydrosphere (water bodies), and lithosphere (land). The biosphere is where all ecosystems and habitats exist, making it the correct answer. Ecology refers to the study of the relationships between organisms and their environment. Habitat refers to the specific place where an organism lives.

The correct answer is "say no, walk away, use body language, and change the subject". These steps can help prevent oneself from getting HIV and pregnancy by effectively communicating boundaries and refusing unwanted advances. Saying no clearly establishes consent, walking away physically removes oneself from the situation, using body language reinforces the message of disinterest, and changing the subject redirects the conversation away from potentially risky topics.

Endurance refers to the ability to sustain physical activity for an extended period of time. It involves both muscular endurance, which is the ability of muscles to repeatedly contract over time, and cardiovascular endurance, which is the ability of the heart and lungs to supply oxygen to the muscles during prolonged exercise. Therefore, the correct answer is muscle and heart/lungs.
