wo structures seen in this animal cell are composed of microtubules are produced by the centriole. What are those two structures?
In cell biology a centriole is a cylindrical cellular organelle composed mainly of a protein called tubulin. Centrioles are found in most eukaryotic cells. A bound pair of centrioles, surrounded by a shapeless mass of dense material, called the pericentriolar material (PCM), makes up a structure called a centrosome.
Why properties of a substance determine how that substance is will react when combined with other substance
It is the chemical properties of a substance, which determines that how the substance will react when combined with other substance.
The usual properties of a substance like density, color, and hardness are some of the illustrations of physical properties. The properties, which illustrates that how a substance modifies into a completely distinct substance are known as chemical properties.
Some of the examples of chemical properties are oxidation, toxicity, the heat of combustion, and flammability, enthalpy of formation, radioactivity, and chemical stability under particular conditions.
Answer:
It is the synthetic properties of a substance, which verifies that how the substance will respond when joined with other substance.
Explanation:
The standard properties of a substance like thickness, shading, and hardness are a portion of the delineations of physical properties. The properties, which outlines that how a substance changes into a totally particular substance are known as compound properties. A portion of the models of substance properties are oxidation, poisonous quality, the warmth of burning, and combustibility, enthrall of development, radioactivity, and compound strength under specific conditions.
Only the water of marine ecosystems contains dissolved salt.
It is indeed true that only the water of marine ecosystems contains dissolved salt. Marine ecosystems, also known as salt water ecosystems, are aquatic ecosystems that waters harbor a substantial volume of dissolved salts. Definite features of individual salt water ecosystems differ significantly, however knowing their total basic surfaces gives an extensive image of their role, value and function. Furthermore, there are so many types of salt water ecosystem, the open ocean is not the only one. Other types include tidal zones, shorelines, estuaries, mangroves, coral reefs, salt marshes and swamps, hydrothermal vents and the ocean floor, just to name a few of the more main groups.

John loves trout fishing so much that he goes trout fishing several times throughout the year. He began to notice that during the dry season the trout had significantly more lice on them than during the rainy season. John, a curious science student, wanted to find out what was causing the increase of lice on the trout. write a testable hypothesis to help John focus his research
A hypothesis could be "the amount of water affect the number of lice found on the trout".
Experiment could be designed with pools with different amounts of water in it. Pools with less water represent the water during the dry season, while those with more water represent the rainy season.
How does solid rock become soil
rocks can become soil in multiple different ways one could be primary succession which means some algae or moss grows onto rocks with out soil then they slowly gain moisture which attracts some other plants like flowers which then breaks down the rock into smaller things then grasses come in and turns it into soil.

Glycolysis provides the pyruvic acid molecules used in fermentation
Glycolysis converts glucose into pyruvate, fueling cellular energy production through fermentation pathways.
Glycolysis is a metabolic pathway that breaks down glucose into pyruvate molecules, providing energy for the cell. In fermentation, pyruvate is converted into other molecules to regenerate NAD+ so glycolysis can continue without oxygen. Fermentation pathways use organic molecules as final electron acceptors derived from pyruvate.

1s22s22p63s23p63d2
I belive the answer is C. 1s2 2s2 2p6 3s2 3p6 4s2
Electron configuration are used to tell the distribution of electrons of an atom or molecule. The electron configuration order should follow a specific path. You will found some similarity of the rule with the number of row in the periodic table. After the electrons fill 3P, the electron should fill 4S before it go to 3D.
Answer: Option (c) is the correct answer.
Explanation:
Calcium is a group 2 element and it lies in period 4 and group 2.
Atomic number of calcium is 20 and its electronic distribution is 2, 8, 8, 2. That is, in ground state there are 20 electrons present in a calcium atom.
It's electronic configuration is as follows.
[tex]1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}[/tex]
Thus, we can conclude that calcium's ground-state electron configuration is [tex]1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}[/tex].

why are the intestines the largest parts of the alimentary canal?
The parts of the alimentary canal listed in order are the mouth, pharynx or throat, esophagus, stomach, small intestine and large intestine. The alimentary canal is the digestive system and includes the parts of the body with which food comes in contact from eating to waste elimination.
The alimentary canal is the whole passage along which food passes through the body from mouth to anus. It includes the esophagus, stomach, and intestines. The intestines carry the food most of the way down, breaking down the food along they way. The intestines carry food from the esophagus to the stomach.
Molecules are different from atoms because they
An atom is the fundamental(smallest) part of matter, that a chemical element can exist. However it may or may not be chemically stable in nature, due to several factors such as its electronic configuration, imbalance in the force of attraction between the nucleus and electron etc… It can broken down into simpler particle, which can depict the characteristics of an element. An atom represents only a single element.
A molecule is a group of chemically bonded atoms(reacted) which may be of similar elements(H2 molecule, O2 molecule) or different (H2O molecule, HCl molecule), which is formed due to the interaction between atoms in different ways, so as to attain chemical and electrical stability
Answer:
An iota is the fundamental(smallest) some portion of issue, that a concoction component can exist. Anyway it could conceivably be artificially steady in nature, because of a few factors, for example, its electronic arrangement, lopsidedness in the power of fascination between the core and electron and so fort.
Explanation:
It can separated into more straightforward molecule, which can delineate the qualities of a component. An iota speaks to just a solitary component. A particle is a gathering of artificially reinforced atoms(reacted) which might be of comparative elements Hydrogen particle, Oxygen atom or extraordinary (H2O atom, HCl atom), or, in other words to the communication between molecules in various routes, in order to achieve compound and electrical security
What’s the difference between a cold blooded animal and a warm blooded animal??
Plzz help
Reptiles and amphibians are ectothermic, or cold-blooded. They are unable to generate their own body heat and thus cannot regulate their own body temperature.
Mammals and birds are warm blooded, which means they can make their own body heat. They can do this when it's too cold for them to survive outside.
In some instances, humans breed animals that are close relatives to produce desired traits. This is called
Artificial selection refers to the process by which humans selectively breed animals with close relatives to enhance certain traits, a common practice in domestication. This selection can affect genetic diversity and requires careful management to avoid health problems due to increased homozygosity.
When humans breed animals that are close relatives to enhance certain traits, this process is called artificial selection. This selective breeding is a common practice in domestication, where species are bred to accentuate traits that are beneficial to humans. For example, a farmer might only breed sheep with the softest wool or dogs with specific temperaments to create or maintain specific breeds. This is different from assortative mating, which is a natural tendency among species to mate with individuals that resemble themselves in some way.
Artificial selection can lead to a change in genetic diversity within a population, often increasing the prevalence of advantageous traits. However, it can also lead to increased homozygosity and the potential for harmful recessive alleles to surface, which is something that needs to be managed carefully to avoid detrimental health effects in the animals.

The nose has mucus, a sticky substance. When outside air passes through the nose, the mucus . Bronchitis, an inflammation of the bronchioles, is a condition in which the bronchioles are filled with mucus. When mucus accumulates, .
i need to fill in the blanks
1. The right answer is the mucus filters the air.
Mucus are different viscous and translucent secretions, little or not very soluble in water, produced by specific glands of various organisms, and in these by various internal organs (eg by the goblet cells of the stomach) or internal mucosa or skin (eg fish, some amphibians, slugs, snails ...).
In humans, mucus produced in the lungs helps to protect the respiratory system by capturing and exporting many of the foreign particles that enter the nose or mouth with each inhalation. In response to inhalation of particles or allergens, mucus secretion increases (reflex and neurohumoral control process), excessively sometimes (in allergic or asthmatic patients).
2. The right answer is less air reaches the lungs (or it blocks the passage of air to the lungs).
Bronchiolitis is an acute infection of the lower airways of viral origin, affecting the small bronchi of infants and young children and spreading in a seasonal epidemic mode.
The clinical picture is due to an obstruction of the airways, on the one hand caused by a mucous plug obstructing the light, on the other hand due to inflammation of the wall. The mucous plug is created by the accumulation of dead cells and mucous secretions. The obstruction is only slightly related to the bronchial spasm, the smooth muscles being little developed at this age.
Answer:
filters the air and less air reaches the lungs

Hope this helps:)
Cold water holds more dissolved oxygen than warm water, impacting marine life and ecosystem health in aquatic environments.
The amount of oxygen that water can hold depends on various factors, with temperature being one of the most significant. Generally, colder water can dissolve more oxygen than warmer water. This is because the molecules in colder water are closer together and move more slowly, allowing oxygen molecules from the atmosphere to dissolve and stay within the water more easily.
Conversely, warmer water has molecules that are more spread out and move more quickly, which makes it harder for oxygen molecules to dissolve and remain in the water. Additionally, warm water often experiences increased biological activity, such as photosynthesis by algae and other plants, which can consume oxygen during the process, further reducing the dissolved oxygen levels.
This phenomenon has important implications for aquatic ecosystems. In areas with colder water, such as polar regions or deep ocean currents, there tends to be higher dissolved oxygen levels, supporting a diverse range of marine life. However, in warmer waters, such as shallow coastal areas or regions affected by climate change, lower oxygen levels can occur, potentially leading to oxygen-deprived "dead zones" where marine life struggles to survive.
Understanding the relationship between temperature and oxygen solubility in water is crucial for managing and preserving aquatic ecosystems and the diverse array of life they support.
