Organisms that have many characteristics in common are grouped into a ’species’ - hope this helped :)
Answer:
complementary base-pairing rules
Explanation:
DNA is the genetic material of living cells. It is a long chain of double-stranded molecules, in which each strand is complementary to one another i.e. Adenine base is paired with Thymine base while Guanine base pairs with Cytosine base following the complementary base pairing rule as proposed by Chargaff. This pairing is responsible for the double helical structure of the DNA.
The complementary base pairs that a DNA molecule contains make it able to produce identical copies of itself during replication or duplication. Before replication of DNA can occur, the double strands need to unwind to form two separate strands, which serves as a template for the synthesis of new complementary strands.
In this manner, each new strand contains one template strand and one complementary strand, which forms two new double helix that is identical to the original strand. This two identical copies of DNA gets separated into two daughter cells, which is the essence of the DNA replication.
Answer:
Obese
Explanation:
Obesity can occur at any age but in recent times more and more children are becoming obese. They develop an unhealthy relationship with food from a young age. Food rather than being a source of nutrition becomes just a source of sensory stimulation.
These children often chew very fast and swallow food without properly breaking it down. Thus they are not able to realize when they are full. They ignore the internal cues for hunger or fullness and keep eating to satisfy their palate. As a result, they become obese.
The teratogens can be defined as any physical, chemical, or infections agents that have the ability to penetrate the protective layers of the embryo, and affect its viability. The overall development and the development of the different organ systems might be affected because of these teratogens. When the embryo is exposed to the teratogens after the organogenesis is complete, it is most likely that the fetus will suffer from the stunted growth. When the organogenesis is complete, the organs are already formed, and hence, no severe damage can occur to them. Down's syndrome will result if the chromosomal abnormality occur in the fetus, which is not likely after the organogenesis is already complete. Any kind of severe anatomical defects are also least likely after organogenesis is completed. Therefore, the chances of having stunted growth are high.
