Answer: A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.
Answer: Endoplasmic Reticulum
Explanation:
The Endoplasmic Reticulum is a network of interconnecting membrane enclosing channels that are continuous from outer outer nuclear envelope to plasma membrane. ER is classified into rough and smooth varieties.
The ER is very prominent in the cell activity synthesizing proteins e.g glycoproteins, lipoproteins and immunoglobins
The answer is B. "<span>The Comprehensive </span>Environmental Response<span>, </span>Compensation, and Liability Act<span> -- otherwise known as CERCLA or Superfund -- provides a Federal "Superfund" to clean up uncontrolled or abandoned hazardous-waste sites as well as accidents, spills, and other emergency releases of pollutants and contaminants into the environment"</span>
From the dichotomous key, the result would be STURGEON FISH.
The sturgeon fish, according to the dichotomous key, has a single dorsal fin, has no fin on its back near the tail and it has a tail that is asymmetrical.
A dichotomous tree is a tool which is used to identify animals. It is made up of a series of choices which lead the user to the correct animal.
Answer:
a. Manipulated variable: TEMPERATURE
b. Responding variable: CRICKET CHIRP
c. Controlled variable: Same species of cricket
d. Hypothesis: IF the temperature is increased, THEN crickets will chirp more
Explanation:
Independent variable, also called the manipulated variable, is the variable that is changed or manipulated in an experiment. In this case, the independent variable is the TEMPERATURE.
Dependent or responding variable is the variable that responds to changes made to the independent variable. The dependent variable in this case is CHIRP OF THE CRICKETS.
Controlled variable is the variable that must be kept unchanged for all groups throughout the experiment. The controlled variable in this case is SAME SPECIES CRICKET USED.
Hypothesis is a testable explanation (via experimentation) to an observed problem or a given question. In this investigation involving Melissa, an hypothesis is: IF the temperature is increased, THEN crickets will chirp more.
