B. The sperm cells swim to the egg cells through their watery surroundings.
- TGA (opal)
Answer:
Explained below
Explanation:
A mutation in a gene that results in total loss of the normal function of the gene product encoded by that gene, resulting in a Null phenotype.
Changes in DNA sequence are termed as nonsense mutation that introduce a stop codon, resulting in a non functional protein. This terminology results stop codons have also worked as nonsense codons.
There are three different stop codon-
In RNA
- UAG (amber)
- UAA (ochre)
- UGA (opal)
In DNA
- TAG (amber)
- TAA (ochre)
- TGA (opal)
Answer:
yes, sexual reproduction leads to the selection of better individuals for a particular environment
Explanation:
Natural selection can be defined as a mechanism associated with the survival and reproduction of individuals better adapted to their environment. Sexual reproduction is able to increase genetic variation, which is the primary source on which natural selection works. In consequence, individuals that exhibit an evolutionary adaptive phenotypic variant will have more chance to survive and to reproduce than those individuals with other less adaptive traits, thereby leading to evolution of the population and tending to optimize phenotypic variants for particular environmental conditions.
