Explanation:
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration help to
release carbohydrates
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
What is the significance of respiration and photosynthesis?The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.
Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.

Read the following summary, which describes blood flow and heart output in space. Then, answer the question.
The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.
What process is being described?
Breathing
Excretion
Homeostasis
Respiration
Explanation:
respiration because it's about blood circulation
Answer:

How do the trachea, bronchi, bronchioles, and alveoli work together to process the oxygen that you inhale?
Answer:
The bronchial tubes divide into smaller air passages called bronchi, and then into bronchioles. The bronchioles end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood. After absorbing oxygen, the blood leaves the lungs and is carried to the heart.
Explanation:
Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water. DNA analysis shows that the two species in each lake are more closely related to each other than they are to any of the other species in the lake. Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
Answer:
The answer is "Sympatric speciation due to disruptive selection"
Explanation:
Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.
23 In any environment or ecosystem, organisms can have several different types of relationships. Three types of relationships are described below. Ecological Relationships Relationship Description Barnacles (small crustaceans) adhere to the skin of a whale in order to be deposited in a new location that is abundant in resources. The whale does not appear to be affected. Fleas attach to the skin of warm-blooded animals, feed on their blood, and make the animals itch. Fungal mycorrhizae live on plant roots and increase the plant's ability to absorb nutrients. The mycorrhizae are provided with carbohydrates from the plant Y Y Z Which of these correctly describes the relationships between the organisms? A X: mutualism Y: parasitism Z: commensalism C X: parasitism Y: commerisallsm Z: mutualism B X, commensalism Y: mutualism Z: parasitism D X: commensalism Y; parasitism Z: mutualism
Answer:
The correct answer is X: commensalism Y: parasitism Z: mutualism
Explanation:
Took a test with the same question
The ecosystem organisms have several different types of relationships. The ecological relationships affect the organism interaction as X: commensalism Y: parasitism Z: mutualism. Thus option D is correct.
What is an ecological relationship?An ecological relationship is an overlapping relationship that an organism has with the environment and is characterized by five types as
competition, predation, commensalism, mutualism, and parasitism.The ecological system all organisms are dependent on each other for food and growth. Thus the fleas attached to the skin of the warm-blooded animals are a sign of parasitism and fungus increases the plant's growth is a sign of mutualism.
