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:
P. aeruginosa
Explanation:
<em>P. aeruginosa</em> is a gram-negative bacteria that belongs to the family Pseudomonadaceae.
From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :
1. Flat spreading colonies with a metallic sheen on SBA - <em>P. aeruginosa</em> is known to produce smooth colonies with flat edges.
2. Fluorescent green color in the media with clear colonies on cetrimide agar - <em>P. aeruginosa</em> is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.
3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - <em>P. aeruginosa</em> has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.
Thus, from all these characteristics one can conclude that the organism in the culture is <em>P. aeruginosa. </em>
Answer:
The chemical level of organization is the simplest level. It includes the building blocks that make life possible. Atoms bind together in various combinations to form molecules that take up several essential functions of life.
Explanation: Hope this helps can I please have brainliest.
Answer:
Living things are classified by scientists in order to organize and make sense of life's tremendous diversity. We can also use classification to learn how living things are related to one another. This also makes it easier for people to study them
Classification aids in our understanding of different types of plants and animals, as well as their characteristics, similarities, and differences. It allows us to see how complex organisms develop from simpler organisms.
Answer:
What previous paragraph? I don't really understand the question but, a molecule is the smallest part of a substance that has physical and chemical properties of that substance.
¿Qué párrafo anterior? Realmente no entiendo la pregunta, pero una molécula es la parte más pequeña de una sustancia que tiene propiedades físicas y químicas de esa sustancia.
