At some point in their lives, all chordates have a flexible supporting rod in their backs called a

Answers

The right answer is notochord.

La chorde (ou notochorde), issue du mésoderme axial, est une structure embryologique cartilagineuse, spécifique de l'embranchement des Chordés (Chordata), auquel appartiennent notamment les Vertébrés (Vertebrata).

Elle constitue une sorte de baguette rigide mais flexible, formée de grandes cellules et située dorsalement entre le tube neural et le tube digestif. Elle est également un important centre de signalisation, produisant notamment la protéine Shh qui permet la formation du sclérotome à partir des somites ou « mésoblaste dorsal » (et donc les vertèbres) et la mise en place de l'axe dorso-ventral du tube neural.

La chorde est entourée de somites qui sont pleins et métamérisés.

The notochord is a flexible rod made out of a material similar to cartilage. If a species has a notochord, it is, by definition, a chordate.

A depression in the ground due to a cave collapse or acidic water dissolution of limestone is called a A. cave. B. stalactite. C. sinkhole. D. stalagmite.

Answers

A cave is a cave...you know, something generally in the rock, something that bears sleep in. It isn't really a depression in the ground. A stalactite is a build up of sediments from the ceiling that drip down to form a icicle shaped rock hanging from the ceiling, and a stalagmite is the same thing, but on the ground. So out of all those choices, I would choose answer D, a sinkhole.

Which of the following materials is damaged by acid rain? quartz marble aluminum glass

Answers

The material that is damaged by acid rain is marble.

Answer:

Option B, Marble

Explanation:

Limestone or marble is severely affected by the acid. Acid rain causes corrosion of all building and sculpture that are made up of marble. The sulphuric and nitric acid in the acid rain reacts with the calcite in the marble to dissolve it. This leads to peeling of marble structure which further exposes black crust made of gypsum formed by the reaction between calcite, water and sulphuric acid.
