What type of plate boundary did subduction occur? Convergent boundary, divergent boundary, transform boundary
charle [14.2K]

Answer:

Subduction is the submerging of one plate under another hence can only occur in convergent boundaries where plates are colliding head on with each other.

Explanation:

Divergent boundary- plates moving away from each other

Transform boundary- plates 'sliding' across each other

The type of RNA that delivers amino acids to the ribosome during protein synthesis is tRNA.a) trueb) false
DENIUS [597]

Answer:

A). True

Explanation:

tRNA, which means transfer RNA is one of the three types of RNA known in nature. The tRNA is found in the ribosome, where it plays a pivotal role in protein synthesis (translation). Transfer RNA is the RNA responsible for reading the nucleotides in the mRNA codon and carrying the amino acid that corresponds those codons to the ribosome.

The tRNA has a 3-dimensional structure that allows it to carry anticodon that reads codon and also carry amino acids on opposite ends. Hence, according to this question, tRNA is a type of RNA that delivers amino acids to the ribosome during protein synthesis.

Cells must be alive to use energy and do work dose passive transport occur in a cell that is dead? Why or why not?
Orlov [11]

Answer:

<h3>Yes, Passive transport can occur in dead cells.</h3>

Explanation:

For passive transport to occur, a concentration gradient has to be formed across a permeable or semi-permeable membrane. If the cell membrane of the dead cell, which is a semipermeable membrane, is intact and a concentration gradient has formed on both sides, passive transport can occur.

A concentration gradient is the difference in the concentration of solute molecules  across the membrane. Passive transport will allow solute molecules to travel from the higher concentration of the solute to the lower concentration across a membrane till equilibrium is reached, that is, both the sides of the membrane has equal concentration of the solute.

The transport of the solvent can occur as well, from higher concentration to lower concentration.
