The most forward two teeth in the upper or lower mouth are incisors
Answer:
True
Explanation:
The embryonic development of fertilized egg includes cleavage, blastulation, implantation, gastrulation and organogenesis.
Cleavage division divides the zygote into blastomeres. First cleavage division result in two blastomeres, second cleavage division results in a transient three cell stage. Third cleavage division forms 8 blastomere. These result in the formation of a sold ball of cells called morula. Morula is 16 cell stage and it descends towards the uterus in 4-6 days. As the morula enters the uterus, it gets a rich supply of nutrients. Trophoblast cells are formed which secrete a fluid into the interior creating a cavity called blastocoel. The inner cell mass now comes to lie on one side as embryonal knob. With the formation of blastocoel, morula is converted into blastula which is called blastocyst in mammals.
Answer:
The
answer to the question is d
Answer:
Option D, polysaccharides
Explanation:
Both Cellulose and starch are polysaccharides which are made up of several polymer units.
A polysaccharide is a sugar which is made up of large number of mono or disaccharide sugar units.
In case of Cellulose, the polymer unit is monosaccharide units of glucose connected by acetal beta linkages
While in case of starch, the polymer unit is again glucose units joined by glycosidic bonds.
Hence, option D
