Why do parrots mimic people?
Answer:
Parrots are intelligent and highly social animals with long life spans, just like people. ... So a domestically-bred parrot, such as a budgerigar, that mimics its people is doing what wild parrots naturally do: they are learning and repeating sounds made by its family and flock mates, who happen to be people.
Explanation:
Parrot expert Michael Schindlinger of Lesley University explained in Scientific American in 2007 that mimicking helps parrots separate members of their own community from outsiders. It can allow a bird to find its mate and prevent intracommunity conflicts over territory.

What is the difference between a scientific law and a scientific theory?
O A. A scientific law has been proved with scientific evidence. A
scientific theory can change when new evidence is found that
does not support the theory.
B. A scientific law is supported by research. A scientific theory is only
an educated guess.
C. A scientific law describes how natural events happen. A scientific
theory is an explanation of natural events.
D. A scientific law involves mathematics. A scientific theory is a
description based on observations.
Answer: I belief its B. A scientific law is supported by research. A scientific theory is only an educated guess.
-Like theories, scientific laws describe phenomena that the scientific community has found to be provably true. Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, where as theories describe how the phenomenon happens.

How did the new island in the Pacific Ocean near the Vava'u Islands form? See below
for a picture of the new islands and for the location on earth.
Answer:
They were created from the subduction of the western-moving Pacific plate under the Australia-India plate at the Tonga Trench. The Tongan Islands sit on the Australia-India plate just west of the Tonga Trench. These volcanoes are formed when materials in the descending Pacific plate heat and rise to the surface.
Explanation:
The new island in the Pacific Ocean near the Vava'u Islands forms as divergent plates allow magma to come to the surface at this location. The correct option is a.

The anterior rami of spinal nerves ______ are called intercostal nerves because they travel in the intercostal space sandwiched between ______.
Answer: T1-T11; two adjacent ribs
Explanation:
The anterior rami of spinal nerves T₁ - T₁₁ are called intercostal nerves because they travel in the intercostal space sandwiched between two adjacent ribs.
What are the rami of spinal nerves?A typical spinal nerve typically branches out into rami as soon as it exits the intervertebral foramen.The smallest of the two main branches is the posterior (dorsal) ramus. It innervates the skin of the back as well as the deep muscles of the back, such as the transversospinalis and erector spinae. The bigger of the two main branches is the anterior (ventral) ramus. The anterior ramus divides into numerous additional branches that innervate the upper limbs, lower limbs, and anterior and lateral regions of the trunk. Numerous anterior rami develop into nerve plexuses.Learn more about rami of spinal nerves here:

why is it necessary for the human body to maintain homeostasis?
Answer:
Conditions in the body must be constantly controlled because cells depend on the body's environment to live and function. The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly.

it's 1 hour
lord have mercy. another genshin player
explanation: divide the distance traveled by the rate of speed. since the distance traveled and the rate of speed are both stated in the same units of measurement, there's no unit conversion needed. so, you can just convert the miles per hour to miles per second, and then convert the total seconds to the hours/minutes or whatever

1) variation in the UV spectra in batch culture. Mineral medium (MM) spectrum (dot), 4-CPh 120 mg L−1 (empty diamond), 4-CPh preozonated (filled triangle). Biodegradation of preozonated 4-CPh by a mixed microbial consortium at 30 h (empty square), 62 h (empty inverted triangle), 102 h (empty circle) of culture, respectively. (B) MM spectrum (dot), 2,4-DCPh 120 mg/L (empty diamond), 2,4-DCPh preozonated (filled triangle). Biodegradation of preozonated 2,4-DCPh by a mixed microbial consortium at 30 h (empty square), 72 h (empty inverted triangle), and 191 h of culture, respectively
2) The UV spectrum profiles of the 4-CPh are compared in Fig. 12.5A. The ozonated spectra show only the presence of organic acids (approximately 20% of the initial COD removal), found in the typical wavelength region for these compounds (210 nm)
3) One can note from this table that oxalic and formic acids are the main identified byproducts for all phenols. Also, all phenolic intermediates different from hydroquinone and cathecol were not detected, nor the organic acids that have been reported in other studies
