Answer:
Which describes farsightedness?
The eyeball is too short for light to focus properly.
Explanation:
This farsightedness best describes longsightedness which has to do with short eyeball for light to be able to focus properly.
Uncontrolled production of cyclin proteins will most likely result in the formation of tumors (Option f).
<h3>What are cyclins?</h3>
Cyclins are proteins that control the progression through the cell cycle by their interaction with specific kinases.
These cyclins-dependent kinases (cdks) can be phosphorylated as a control points during the cell cycle.
Uncontrolled production of cyclins will produce uncontrolled cells that divide forming tumors.

Answer:
A) one human somatic cell
Explanation:
A human genome is a complete set of DNA in somatic cell and it contains 23 chromosome pairs (nuclear genome). Beside nuclear genome cell also have mitochondrial genome. Unlike somatic cells (diploid-two sets of chromosomes, one from mother and one from father), germ cells (egg cell and sperm cells) are haploid, have only one set of chromosomes.
Human genomes include genes that are protein-coding but also noncoding DNA.
The right answer is A: Enzyme activity decreases at these temperatures
Temperature influences the activity of the enzymes responsible for assisting with chemical reactions in the Calvin cycle. When temperatures are low, enzyme activity is slow. As temperatures increase, the activity of the enzymes that assist in these chemical reactions also increases to a certain extent, which is the optimal response to temperature. It is at this point that the rate of photosynthesis of plants is the highest.
As the temperature continues to rise beyond this point, the enzyme activity decreases until photosynthesis stops. It is important to remember that the rate of photosynthesis in C3 plants is higher in cold conditions, whereas it is the opposite in C4 plants.
Answer:
RNA Polymerase is the enzyme responsible for the synthesis of RNA
Explanation:
Ribonucleic acid [RNA] is synthesized from DNA in a process known as transcription. this process is facilitated by RNA polymerase enzyme. The corresponding RNA produced is complementary to the parent DNA
While DNA is usually double-stranded, RNA is single-stranded and they are synthesized from each strand of DNA.
RNA polymerase is responsible for unwinding the double strands of DNA and copying the information into the newly formed RNA strand.
