B. epidermis
C. guard cell
D. spongy mesophyll
The structure of plants that allowed the first land plants to survive out of water is known as the cuticle. Thus, the correct option for this question is A.
The first plants that were tends to live on land are the Non-vascular plants, which include mosses and liverworts, which were the first-ever land plants. They do not have much of an internal support system but have slightly simpler material for the same tasks.
Early in their history, land plants also evolved a cuticle. The cuticle is the structure that involves a waxy layer on the outer surface of the aerial parts of a plant that helps to prevent water loss. Sometimes cuticle with details of epidermal cell structure is preserved in fossil plants.
Guard cells play an important role in the opening and closing of the stomata. While epidermis is the outer cell which prevent the whole plant form injury.
Therefore, the structure of plants that allowed the first land plants to survive out of water is known as the cuticle. Thus, the correct option for this question is A.

Answer:
A
Explanation:
Living organisms use 20 standard amino acids to make proteins, as coded by DNA. However, there are additional ones that are modified post-translation into proteins, raising the actual total number of amino acids found in a living organism.
In living organisms, there are 20 standard amino acids that are used to make proteins. These comprise the basic set of amino acids encoded by the genetic code. However, there are additional amino acids, not directly coded for in DNA, that are modified after being translated into proteins, like hydroxyproline and selenocysteine, making the actual total number of amino acids in a living organism somewhat higher than 20.

Likeanimals, plants must maintain an internal balance, or homeostasis. All theliving organisms must be able to maintain homeostasis in their environment andalso to themselves to avoid dysfunction in their bodily system and continue toadapt tp the dynamic surroundings.
2. in its xylem
3. in its roots
4. in its palisades and spongy cells​
The strengths of the model the student created are it is clearly labeled and shows that oxygen and carbon dioxide is going in which direction.
A model is something that graphically describes any reaction or process. A model is made up of plastic or any solid material with colors. A model is a good way to show any process or work that has to be done at a big pace.
The model shows the movement of gas into and outside the body. The oxygenated blood transfer into the blood and the deoxygenated blood goes into the lungs.
Thus, the student's model has the advantage of being clearly labeled and showing which way oxygen and carbon dioxide are moving.

Like and Rate!!
One strength of the model is that it clearly shows which gases are taken in and which gases are released for exhalation.
