The Appalachian Mountains were formed due to a continental collision, which might have occurred more than 270 million years ago.

<h3>What is plate tectonics?</h3>

The expression 'plate tectonics' makes reference to the creation of landforms due to Earth's movement.

The Appalachian Mountains were formed due to the collision between different continental plates.

In conclusion, the Appalachian Mountains were formed due to a continental collision, which might have occurred more than 270 million years ago.

What specific spinal nerve branch controls the movement of rectus abdominis
CaHeK987 [17]

Answer:

The correct answer will be-ventral ramus

Explanation:

Rectus abdominis is a skeletal muscle found in the front part of the body which begins from the sternum and ends at the pubic zone.

Rectus abdominis is also known as "Abs" which viewed externally appears to be six, eight or ten in number.

These muscles are innervated by the thoracoabdominal nerves which carry and transmit signals to CNS and to the muscles back. The main spinal nerve which controls the movement of Abs is known as the "ventral ramus".

Thus, ventral ramus is the correct answer.

What are the factors that contributed to the success of pteridophyte as land plant
Anna35 [415]

Two factors contributed to the success of the pteridophytes: the extreme miniaturization of the gametophytic generation and an important development of the sporophytic generation (development of the tree forms).

Pteridophytes are a group of plants that peaked in the Carboniferous (-300 million years). It is the first great terrestrial plant civilization. These plants would have appeared in the Devonian -400 million years ago, perhaps from certain primitive terrestrial plants which, unlike bryophytes, would have favored the diploid generation on the haploid generation.

Particularly well adapted to terrestrial life, they have created, thanks to the development of tree forms, immense forests whose fossilization is at the origin of coal deposits.

Pteridophytes are at the origin of an evolutionary lineage based on the extreme miniaturization of gametophytic generation and an important development of sporophytic generation, leading to all tracheophytes including current flowering plants. Pteridophytes are well adapted to terrestrial life, however fertilization still requires the presence of water since male gametes are swimmers.

LuckyWell [14K]

Answer: The correct answer is option C

FACILITATED DIFFUSION.

Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).

Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.
