Answer:
Viscosity
Explanation:
Ive had this question on quizzes many times. And viscosity was the answer.
The limiting factor on the population of Arctic foxes is density-dependent. In population ecology, density-dependent processes happen when population growth rates are regulated by the density of a population. Density-dependent factors are factors where the effects on the size or growth of a population vary with the density of the population itself.
<h3><u> Answer;</u></h3>
B. organelles
<h3><u>Explanation;</u></h3>
- Eggs contribute 50% of the chromosomes as well as cytoplasm and cellular mechanisms required for the cell to thrive and replicate.
- Mitochondria for example are particularly important to the embryo but are only passed from mother to child via the egg.
- Sperms on the other hand, are just packets of DNA.
Smooth muscle is the type of muscle tissue responsible for propelling food along the digestive tract.
Smooth muscle is a type of muscle tissue that can be found in the walls of hollow organs of the body such as the digestive system, urinary tracts, tubes such as blood vessels and reproductive system. Smooth muscles contracts involuntarily and allows the walls of organs to move. The layer of smooth muscle present in the digestive system helps to break down food and propel it along the tract. Food substances and liquid moves from one organ to the next through the muscle action.
Answer:
<h2>Ear has three main parts; outer most part is called outer ear, middle one is as middle ear and innermost as inner ear.
</h2>
Explanation:
1. Outer Ear: Pinna (the outer, funnel-like part), Ear Canal (Conducts sound vibrations from the pinna to the tympanic membrane), and Tympanic Membrane.
2. Middle Ear: Ossicles (Tiny bones that amplify sound waves), Malleus, Tensor Tympani, Incus (Connects the Malleus to the Stapes; receives vibrations from the Malleus and looks like an anvil), Stapes, Stapedius, Oval Window (Receives vibrations from the Stapes and is the flexible opening to the cochlea).
3. Inner Ear: Cochlea (The main structure in the inner ear; tiny coiled structure); Tympanic Canal, Vestibular Canal, Basilar Membrane, Cochlear Partition , Round Window Organ of Corti.
.
Route of Sounds: External environment → Collected by the pinna → Through the ear canal → Vibrates the Tympanic Membrane → Vibrates the ossicles → Vibrates the Oval Window → Sends “Traveling Waves” through the Vestibular Canal → Pressure released by Round Window if necessary → Inner and Outer hair cells transduce the vibrations.
