Answer:
The answer is B
Explanation:
Its B because the definition of species is "a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding."
B. tree roots growing downward because of gravity
C. sunflowers turning toward light
D. vines curling around a fence
I AM THinking b but im not sure
One example that is not a behavioral adaptation in plants is tree roots growing downward because of gravity. The correct option is B.
Behavioral adaptation is what creatures do to survive. If we are talking about animals, the behavior can be acquired and carried down over generations, or it can be an innate adaption, which entails adaptions being passed down through generations genetically.
Individual organisms or entire groups can benefit from behavioral adaptations. Behavioral adaptations are actions taken by a plant to increase its chances of survival. Tropisms are an example of a behavioral adaptation in plants. Tropism refers to plant growth toward sunlight.
Roots growing downward due to gravity is not an adaptation because it is a natural cause, adaptations are the ones that save them from extreme conditions.
Therefore, the correct option is B.

Ans.
The membrane proteins that pump sodium ions out of the cell from inside and potassium ions inside the cells are called as sodium-potassium pumps or sodium-potassium ATPases.
These proteins perform active transport by using energy from ATP hydrolysis and transport two potassium ions inside the cells, along with transport of three sodium ions outside the cells, against the concentration gradient.
Thus, the correct answer to complete the sentence is sodium.
If the cell membrane does not allow the water or solute particles to pass through it then the cell will be deficient in those particles which could even lead to the deathof cell.
The animal cell has an outermost covering which is known as the cell membrane or the plasma membrane. It is selectively permeable in nature. It only allows some solute particles to move across it. The cell membrane does not allow all the particles to move across it, as a result the restricted particles requires a protein or ligand through which it can cross the membrane.
Cell membrane is made up of phospholipids and membrane proteins. Their is a lipid-bilayer in which some proteins are embedded are known as integrated proteins and some are present on the membrane. Cell membrane is present in all types of cells, however a cell wall is also present in plants outside the cell membrane.
