D. Gene splicing. They remove specific genes in order to create a transgenic organism.
Very large astroids broke apart to form rocky planets, including earth and Dacia is playing it slowly change to rocky planets after colliding with meteorites
Answer:
1. c
. The life cycles of insects and animals all start from a fertilized egg.
2. d
. A bee goes through a pupa stage, while the grasshopper goes through a nymph stage.
3. b
. I and II
Explanation:
The egg fertilization is very important for the emergence of almost all organisms. If the egg is fertilized then it will change into an organism otherwise no organism is produced from that unfertilized egg. The bees has four distinct life stages i.e. the egg, larva, pupa and adult whereas grasshopper has three stages i.e. egg, nymph, and adult. A moth and an eagle both start their life cycle as a fertilized egg and moth and an eagle both hatch from an egg which is laid by the mother outside of their body..
Acid-fast and Gram is used to visualize the structures in a membrane.
It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>
Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.
They stain poorly with Gram stain procedure, and appears as weak Gram-positive.
Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids, and
<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>
To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.
