Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
Answer:
This is false. Modern humans evolved from great apes.
Answer:
It connects amino acids.
Explanation:
The process of synthesis of proteins is known as Translation. The process takes place inside the ribosome and involves tRNA and codons. The proteins are synthesised in their linear form which is composed of monomer units called amino acids.
The amino acids are therefore known as the building blocks of the proteins. These amino acids possess a carboxyl group (-COOH ), an amine group (- NH₂) and -R group.
A bond is formed between -COOH and -NH₂ in the amino acids which links the two amino acids together releasing a molecule of -H₂O, therefore, called dehydration method. This bond is known as a peptide bond which is involved in the formation of amino acid.
Thus, the selected option is the correct answer.
Answer: uncharged particle found in atomic nuclei
Explanation: A neutron is one of the three components of an atomic nucleus. A neutron has no charge that is, it is unchanged. An atom has three components: electrons, protons and neutrons. The neutrons and protons are located inside the nucleus of an atom while electrons are found outside the nucleus where they revolve round the nucleus. The number of neutrons and protons in a nucleus of an atom makes up the mass number of an element.
The similarities are: 1. Both are compounds, different types of atoms.
2. Both contain H and O 3. Both are formed form covalent bonds or non metals.
3. Both are clear liquids at room temperature.
Hope this helps!
