1. Genetics and environment influence the trait as it depends upon the adaptation made according to availability and environment.
2. Traits are passed onto either parents after fertilization when 2 genes from either parent is received.
3. Dominant trait is responsible for the phenotype of the individual.
4. The expression of gene is seen by the phenotype expressed depending upon the environmental factors.
Explanation:
The food preferences are based on the traits adapted over the time for digestion and method of eating due to natural selection. The occurrence of beneficial trait for digestion become common in the population as these traits are transferred for better survival and evolution.
The traits in an organism is passed on from parents. During fertilization one allele from each parent is passed onto the progeny. 2 alleles together are called gene. In the process of meiosis only one chromosome is present in germ cell hence no homologous chromosome thus only one allele for the trait is present in each parent.
The alleles of dominant trait mask the effect of recessive alleles during phenotype expression. According to law of complete Dominance the dominant trait gets expressed and recessive trait do not get expressed.
The temperature, external environment, chemicals, light factor, diet etc influences the expression of genes in certain organisms. The effect of these can be seen on the phenotype of the organism.
Lysogenic cycle commonly
occur in eukaryotes and is a process where viral DNA or RNA is integrated into
the host cell as a new set of genes called prophage. However, the Viral DNA
becomes the part of the cells genetic materials.
Steps involves during
lysogenic cycle:
1) Cell enters the viral genome
2) Integration of the viral genome into the host cell genome
3) Viral chromosome is copied by the host cell using DNA
polymerase
4) Cell division occurs and transfers of virus chromosomes
to the daughter cell
5) Any trigger in virus will result into detachment of viral
genome from the host cell’s DNA.
Answer:
The plant could be a cacti or some other plant with spikes on the leaves.
Explanation:
Answer:
The options
a.social moral reasoning.
b.conventional moral reasoning.
c.postconventional moral reasoning.
d.preconventional moral reasoning.
The CORRECT ANSWER IS b.
b.conventional moral reasoning.
Explanation:
The conventional level of moral reasoning is particular of adolescents and adults. To think in a conventional way is to presume the morality of actions by contrasting them to society's opinions and standard.
In this case, the morality of an action relies majorly on peer acceptance.
Take for instance: I would turn down the act of drinking and driving due to what my friends will reason of me and my perception of belittling myself.
Conventional moral reasoning judges an action by its compliance to society's rules so as to promote social order just as in this case study.
DDT affects the environment negatively. In the past, DDT was known to not cause harm in human because the molecules of DDT are not absorbed by the human skin. But new studies suggested that humans actually have DDT on their bodies and it stays on the liver, kidneys and others. DDT is being used in agriculture; it would be drained into the bodies of water where fishes live, the fishes will then be eaten by birds, humans and other predators. This flow of contamination shows the interdependence of life on earth.
