Answer:
Ang isang monopolyo at isang oligopoly ay mga istruktura ng merkado na umiiral kapag mayroong hindi perpektong kumpetisyon. Ang isang monopolyo ay kapag ang isang solong kumpanya ay gumagawa ng mga kalakal na walang malapit na kapalit, habang ang isang oligopoly ay kapag ang isang maliit na bilang ng medyo malalaking kumpanya ay gumagawa ng katulad, ngunit bahagyang magkakaibang mga kalakal.
Answer:
Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species
Explanation:
Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.
Answer:
Explanation:
Three-parent baby, human offspring produced from the genetic material of one man and two women through the use of assisted reproductive technologies, specifically mitochondrial manipulation (or replacement) technologies and three-person in vitro fertilization (IVF). In general, the reproductive technologies used to produce three-parent babies focus on replacing or otherwise reducing the effects of mutations that occur in the DNA of cellular organelles known as mitochondria, which reside in the cell cytoplasm. The various approaches could help women to overcome infertility and could prevent the transmission to their offspring of potentially debilitating mitochondrial diseases.
There are basically 3 types of pharynx- nasopharynx, oropharynx and laryngopharynx.
The function of the pharynx are:-
1. To transport the food from mouth to esophagus.
2. To warm, moisten and filter the air, before it moves to the trachea, and then to the bronchi, the bronchioles, the alveoli and at last to the lungs.
Therefore, pharynx(or throat) is a part of both- digestive and respiratory systems.
3. It is also important for vocalization.
