<span>This is an example of facilitated diffusion using a channel. Diffusion is the process of an object moving across a concentration gradient, usually from areas of higher to lower concentration in membranes. In this case, the diffusion is "facilitated" by the aquaporin molecules and water is allowed to enter or exit the membrane based on concentration level.</span>
Answer:
ionic
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
There are one valance electron in sodium so it needed to lose one valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus electrons lost by sodium atom is gained by atom of chlorine and form ionic compound.
2Na + Cl₂ → 2NaCl
Answer:
it´s <u><em>B</em></u> the answer is B
Explanation:
thats just the answer i think not too sure really but feel free to correct me is you like my dude.
<span>Like watercolor, the substance that can be applied in a translucent wash, that is well suited to large areas of flat, saturated color is called a gouache. It makes the colors opaque like an inert pigment which is colorless in paints. </span>
Answer: within the first year, within the second year
Explanation:
Many toddlers start to sit, stand and walk by the age of 9 to 15 months of age. These are because of the changes that occur in the brain and the spinal cord. By the age of two the brain develops coordination with the muscles of the body and the infant establishes balance on the feet and hip muscles becomes strong that aids in achieving the squatting position.
