The correct answer is phototrophism.
Phototrophism is said to be the growth of a plant toward a source of light.
It is response to the stimulus of light and is seen when a plant bends towards the direction that light is coming from. Response by plants to a stimulus is called tropism. The word or prefix "photo" means or refers to light. Therefore phototropism simply means response to light.
Phototropism can be especially evident in the jungle where the jungle floor gets very little light. If a tall tree falls to the ground, it leaves a gap in the canopy through which sunlight streams to the ground. Many jungle plants growing on the ground will bend towards the gap and rapidly grow towards the source of light.
Degeneracy
Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 <span>nucleotides that codes for a specific amino acid.
Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate. </span>
Answer:
It is maternal inheritance (cytoplasmic inheritance) of the gene for petal color.
Explanation:
In the given experiment, the color of the petal is regulated by maternal inheritance. In the first step, the true-breeding pale plant was pollinated by a true-breeding normal plant, therefore, all the F1 was identical in terms of petal color to the female plant (the true breeding pale plant).
In the second step, the F1 pale plants were pollinated by the true breeding normal plant. Again, the petal color in the progeny was determined that the female parent (the F1 pale plant). If true breeding normal plants will be pollinated by true breeding or F1 pale plant, the progeny will exhibit "normal phenotype" for petal color since the female plant has normal phenotype here.
There are several ways to treat or cope with presbycusis (age-related hearing loss). Here are some of ways:
1. Hearing Aid(s)
2. Implants (Cochlea, Middle ear) - involves surgical operation
3. Lip reading or speech reading training
4. Hearing assistive devices - sound amplifying devices (cellphones, tablets, etc.)
It would be best to refer to an audiologist or otolaryngologist to for extensive diagnostic evaluation of the gravity of hearing loss and seek proper medical treatment.
