I believe the correct answer is C.
Answer: D. The genes for antibiotic resistance help the transformed bacteria survive in their environment.
Explanation:
First and foremost, we should note that plasmids used in the delivery of DNA typically consists of genes which helps in antibiotic resistance.
Based on the question given, we should note that the genes for antibiotic resistance help the transformed bacteria survive in their environment. This is because cells that have been treated with plasmid are able to survive and grow compared to those that have not been treated with plasmid which are eventually killed by the antibiotic.
Answer:
Water
Oxygen
Carbon dioxide
Lipids
Explanation:
The plasma membrane is a lipid bilayer with a hydrophobic core made of nonpolar tails of phospholipids. The plasma membrane allows only uncharged, small and hydrophobic substances to pass through it. Charged particles such as ions, polar molecules such as sucrose can not cross the hydrophobic core of the plasma membrane.
Oxygen and carbon dioxide gases have small sizes and can diffuse through the spaces between the tails of phospholipids of lipid bilayer of the plasma membrane without any transport proteins. Lipids are hydrophobic and therefore, do not need any transport proteins to cross the lipid bilayer. The small water molecules are also free to move through the membrane.
Vaporizations from oceans
Passive agglutination - antibodies or antigens attached to particles (ex:latex beads)
-produced commercially
-beads mixed with drop of body fluid or bacterial culture
