Answer:
DNA replication
Explanation:
DNA is the genetic material and serves to store genetic information. The genetic information is transmitted from a parent cell to the daughter cells or from the parent to the progeny by the process of DNA replication.
DNA replication is the process that occurs in the nucleus in eukaryotes and includes the synthesis of new DNA strands using the existing DNA strands as a template. The newly formed DNA molecules are then distributed among the daughter cells during cell division. Thereby, the process of DNA replication ensures that the DNA of the parent generation is carried to the next generation.
For instance, sperms and egg cells in humans carry the DNA of male and female parents respectively to the young one. DNA replication occurs in sperm mother cells and egg mother cells during the formation of sperms and egg cells respectively.
Every other organism other than bacteria or archae is eukaryotic.
(eukaryotic organisms are organisms whose cells have a nucleus, and prokaryotic organisms are organisms whose cells DON'T have a nucleus.)
Answer:
a) Two reasons why polythene bags are not environment friendly are as following:
- Plastic bags are made up of non-renewable materials such as polypropylene and their manufacturing and disposal cause greenhouse gases to release in the environment and contribute to global climate change.
- Polythene bags or Plastic bags are non-degradable and break into small pieces in the environment which are then consumed by wildlife or run off into oceans.
b) Yes, the decision of using paper bags is correct as it will minimize the use of plastic bags and also reduce the environmental pollution caused by plastic waste. Paper bags can be reused or recycled again and again and they are easily degradable in the environment causing very less or no pollution.
c) The values associated with the ban on use of polythene bags is to establish a sustainable environment for our present and future generation. It will reduce environmental pollution and will minimize the effect of global warming.
Answer:
True
Explanation:
Let the allele for green color of pods be G
and the allele for yellow color of pods be g
Phenotype of true breeding parent with green colored seeds is GG
Phenotype of true breeding parent with yellow colored seeds is gg
In F1 cross
GG mates with gg
Genotype of offspring - Gg
Phenotype of offspring - Green seed
Since the offspring has both the allele for green and yellow seeds color but yet only green is expressed. This indicate that green allele dominated the expression of yellow allele thus, it can be concluded that green seed pods were dominant over yellow seed pods.
