Answer:
Explanation:
Bicoid gene is the maternal effect gene whose protein concentration gradient patters the anterior-posterior axis in Drosophila embryogenesis. It was the primary protein that is demonstrated to act as a morphogen. Morphogens are proteins whose concentration gradient will affect the developmental fate of the surrounding region.
The specified bicoid gene is the one which codes for bicoid protein. This protein is being existing in a gradient manner in the egg and thus its concentration is higher at the anterior end and lower in posterior end.
This bicoid protein is responsible for the stimulation of the development of the anterior end.
The posterior region (including the hindgut) expands and extends towards the anterior pole along the dorsal side of the embryo. At this time, segments of the embryo become visible, creating a striped arrangement along the anterior-posterior axis.
The answer could be A.
A bacterial cell is about 0.2-20 um, while a typical eukaryotic cell is about 10-100um, according to many sources of research.
Answer:
i would say A. Both are needed as a reactant of cellular respiration.
Explanation:
While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. ... Without oxygen, much less ATP would be produced.Aug 31, 2018
