Answer:
The function of catalase is to protect cells from toxic effects by some reactive chemicals, such as hydrogen peroxide.
Explanation:
As a result of the metabolism, each organism causes some chemical substances to be produced, for example, hydrogen peroxide. Catalase catalyzes the reaction, decomposing hydrogen peroxide to compounds less dangerous for cells, for example, in water and oxygen. In the following reaction the function of catalase is shown:
2H2O2 -----------> 2H20 + O2
Answer:
any change at the third codon position
Explanation:
The genetic code is considered to be degenerate because a single amino acid may be coded for more than one codon. In this case, Leucine (Leu) is an amino acid that can be encoded by four different codons: CUU, CUC, CUA and CUG codons. In consequence, all nucleotide changes (mutations) at the third codon position don't affect the synthesis of Leu. This type of mutation that does not alter the sequence of amino acids is called silent mutation.

Explanation:
Given what we know, we can confirm that plant root cells get their energy through a veinous transport system within the plant as well as containing a higher concentration of mitochondria.
<h3 /><h3>Why do root cells contain more mitochondria?</h3>
This has to do with the function of this organelle. The mitochondria are responsible for producing the energy needed by the cell. The root cells require more of this energy in order to undertake active transports of nutrients, which is the reason they contain more mitochondria.
Therefore, we can confirm that plant root cells get their energy through a veinous transport system within the plant as well as contain a higher concentration of mitochondria.

Answer:
Option D, Five radish plants are grown in sunlight, while another five radish plants are kept in the dark.
Explanation:
In a controlled experiment, impact of one independent variable is studied on the dependent variable.
Here in this study sunlight is the independent variable while the radish plant is dependent variable.
The researcher wants to study the effect of sunlight on radish plants when they are exposed to it and compare it to the effect created on radish plants that are kept in dark.
Hence option D is correct.
