Answer:
a) i) Xylem
ii) Upper epidermis
iii) Stoma
iv) Chroloplast
v) Palisade cell layer
b) By a waxy layer on the cuticle of the leaf
Explanation:
The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.
The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.
Answer;
Water has polar bonds and is a polar molecule.
Explanation;
-Water is important in life of living organisms. The major important properties of water include; Its attraction to polar molecules
,high-specific heat, high heat of vaporization, the lower density of ice
and High polarity.
-Water's attraction to other water molecules, is one of the major properties of water. Water's polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together.
-Water's attraction between molecules of a different substance is called adhesion. Water is adhesive to any molecule it can form hydrogen bonds with.
Answer:
When bacteria are exposed to an antibiotic, such as penicillin, they often mutate.
Explanation:
This means that part of their DNA changes, giving the antibiotic resistance to the bacteria.
In this way, the bacteria can generate a copy of their DNA and transmit it to their offspring, giving their resistance.
On other occasions, a resistant bacterium dies from causes unrelated to the antibiotic, leaving its DNA free.
If other bacteria manage to capture that DNA, it will also acquire antibiotic resistance.
