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.

Lyophilization Methods of microbial control do not rely on protein denaturation and/or disruption of cell membrane integrity
Lyophilization Freeze-drying or freeze-drying is the process of freezing the product and placing it under vacuum, then removing the water from the product, allowing the ice cream to go directly from solid to vapor without going through a liquid phase. Freeze-drying is a water removal process commonly used to preserve perishable materials, extend shelf life, or make materials easier to transport. Freeze-drying is to sublime the frozen water in the material by lowering the pressure and applying heat after freezing the material. Lyophilization converts pharmaceuticals into stable solids by removing water from liquids

Answer: D
Explanation:
Many unicellular organisms live in bodies of water and must move around to find food. Most often, they must obtain nutrients by eating other organisms. Plant-like protists, and some types of bacteria, can make their own food through photosynthesis.
