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.

Which statement est describes how organisms and populations depend on abiotic fertors in
an ecosystem?
A Algae is the main diet of tadpoles.
B Woodpeckers nest in dying trees.
с Worms dig tunnels 'n soll.
D
Gids nest in cattail plants
"Worms dig tunnels in soil", best describes how organisms and populations depend on abiotic factors in an ecosystem. Therefore, option (C) is correct.
What are abiotic factors?Abiotic factors are non-living aspects of the environment that have an effect on living things. In this scenario, worms are considered to be biotic factors; however, the abiotic factor of soil is required for the worms' tunneling activity in the soil. The behavior of worms and the impact that they have on the ecosystem can all be influenced by the moisture level, texture, and nutrient density of the soil.
Therefore, choice (C) illustrates how organisms' ability to survive and perform their roles within an ecosystem is contingent on the presence of abiotic factors.

Compare and contrast the location and function of ribosomes in prokaryotic and eukaryotic cells.
Answer:
Explanation:
In eukaryotic cells, ribosomes are found in the cytosol of a cell, the mRNA , endoplasmic reticulum and also the matrix of the mitochondria. They are large molecules that catalyzes the synthesis of proteins, which is called translation. The ribosome choose tRNA and covalently links the amino acids into a polypeptide chain.
In prokaryotes, it can be found in cystosol and it help translate genetic code into protein.

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.

The hypothalamus is the link between the nervous system and the endocrine system. The pituitary gland is called the master gland because it influences the release of hormones by other glands in the endocrine system, malfunctioning of which releases growth hormone, which can lead to gigantism.
What is Pituitary gland?The pituitary gland is defined as a small, pea-sized endocrine gland located at the base of your brain below the hypothalamus that releases several important hormones and controls the function of many other endocrine system glands.
There are four hormones which is secreted by the anterior pituitary gland that control the functions of other endocrine glands where these hormones include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), and luteinizing hormones (LH). The pituitary gland is called the master gland.
Thus, the hypothalamus is the link between the nervous system and the endocrine system while the pituitary gland is called the master gland

Through which of these will light waves travel with the greatest speed? PLZEXPLAIN Y THE ANSWER IS CORRECT
a. Air
b. Glass
c. Vacuum
d. Water
Answer: The correct answer is C. Vacuum.
Explanation: It was correct on my test : )
why it is important to know the speed of earthquake waves, the strength of the waves and how do we determine the location of the epicenter of an earthquake. ?
Answer: As the P and S waves travel out from an earthquake the P waves get progressively farther ahead of the S waves. Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave.

What happens in sickle cell anemia?In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the sequence of amino acids in β-globin, with valine being incorporated instead of glutamic acid. This constitutes a mutation of the missense type.
Missense mutations are characterized by the substitution of one nucleotide by another in the DNA sequence —a point mutation— whose consequence is reflected in the transcription and substitution of one amino acid by another in a protein, whose structure or function will be altered.
The change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease.
Therefore, the type of mutation will affect the largest number of proteins produced by an organism is Missense mutation. Thus, option D is correct.
