HOPE I HELPED
Explanation:
They share electrons and form a "compound bond".
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.

In Summary: Lipids
Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.
all living cells have enzymes.
B)
life would not be possible without enzymes.
C)
enzymes can speed chemical reactions by 100s to millions of times.
D)
there are a few types of enzymes, but they each perform many types of reactions.
The incorrect statement about enzymes is that there are only a few types, each capable of performing many types of reactions. In reality, there are thousands of enzyme types each specifically designed for a particular type of reaction.
The subject of this question is about enzymes, which are proteins functioning as biological catalysts. They speed up chemical reactions and are vital to life. The options A), B), and C) state that all living cells have enzymes, life would not be possible without enzymes, and enzymes can speed up chemical reactions by hundreds to millions of times. These options are all true. But the statement D) that there are a few types of enzymes, each performing many types of reactions, is incorrect. In fact, there are thousands of different types of enzymes and each enzyme usually only catalyzes one type of chemical reaction.

They knew they would be left behind by the scientific community if they did not.
They needed to discredit Darwin as quickly as possible with contradictory evidence.
They were compelled to prove that this new idea was correct and Lamarck was wrong.
Answer:
Its because they wanted to see if the concept of natural selection fits in the evidence they found in their experiments or not.
Explanation:
Charles Darwin proposed the concept of natural selection. The same context of "Survival of fittest" used by Herbert Spencer was asserted by Darwin as "Natural Selection".
The movement of water from an area of high water concentration to an area of low water concentration is known as osmosis. Diffusion is also one such mechanism in which particles move from high concentration to low concentration. But, there is a difference between diffusion and osmosis. In osmosis, the movement occurs through a semi-permeable membrane. In cells, plasma membrane acts as semi-permeable membrane. Osmosis is a very important phenomenon to sustain life in biological systems because it helps in maintaining homeostasis. Homeostasis on the other hand is a process which aids living beings in regulating their daily activities so as to maintain stable internal environment. For example, if a cell becomes dehydrated (flaccid cell), then it can be easily rehydrated by keeping it in an environment full of water i.e. a hypertonic solution . The water will enter into the cell by osmosis thereby making it rehydrated again.
