Vertebrates have a backbone and an ____.
The word that completed each sentence should be
1. exoskeleton
2. endoskeleton
An exoskeleton refers to the skeleton that is external in nature at the same time it supports and protects the body of the animal. While on the other hand, the endoskeleton refers to the internal skeltion. So we can say that invertebrates should contain the exoskeleton with respect to protection and support. While the vertebrates should contain the backbone also the endoskeleton.

Explanation:
b. more air to push through the rima glottidis
c. more taut vestibular folds
d. longer and thicker vocal folds e) wider arytenoid cartilages
Answer;
c. It led to the development of contact-inhibition regulators.
Explanation;
-While normal cells possess mechanisms that inhibit proliferation when conditions are inappropriate, tumor cells circumvent these mechanisms and continue proliferating.
-Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells.
Answer;
A. of a private residence becoming publicly important
Frank Lloyd Wright's Fallingwater house is best described as an example of a private residence becoming publicly important.
Explanation;
Frank Lloyd Wright first became known for his Prairie Style of architecture which incorporated low pitched roofs, overhanging eaves, a central chimney, and open floor plans which, he believed was the antidote to the confined, closed-in architecture of the Victorian era.
Falling water is a house designed by architect Frank Lloyd Wright in 1935 in rural southwestern Pennsylvania. The house was designated a National Historic Landmark in 1966.
Answer:
A. of a private residence becoming publicly important

Part B: Describe in detail their experiment. Include what they used to simulate the conditions of early Earth, and what their results were. (3 points)
Answer:
A// If early conditions of primeval earth had ammonia, methane, hydrogen in its atmosphere, then it is possible that amino acids such as glycine, α-alanine, and β-alanine may have been spontaneously formed from chemical reactions spurred by energy from lightning.
Their hypothesis was that the early conditions of primeval earth favored the spontaneous formation of organic molecules, from inorganic precursors, that may have been the origin of life. This theory is called abiogenesis.
B//Miller Urey put methane, ammonia, hydrogen gases in a glass flask and a pool of water at the bottom of the glass flask. The flask was heated moderately to simulate the hot conditions then. Sparks were also occasionally induced in the flask to mimic lighting. The flask was then cooled slowly to simulate cooling of earth over time.After one day, they found the presence of some amino acids (glycine, α-alanine and β-alanine) was discovered in the water in the flask
