The process of apoptosis, I believe, is when the tadpole's tail is reduced in size during metamorphosis.
In most animal phyla, metamorphosis actually takes place in conjunction with morphological, ecological, and physiological changes.
Marine invertebrates' larva behaves as a drifting tiny creature in the ocean, expanding its habitat distribution to find the best location for its survival.
When muscle cells undergo apoptosis, which is the final stage of their metamorphosis, they are split into membrane-bound muscle fragments and consumed by macrophages.
As a tadpole becomes a frog, apoptosis occurs. The cells in its tail are induced and it will be lost.

Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane. Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. ... Channel proteins form open pores through the membrane, allowing the free passage of any molecule of the appropriate size.t is the proteins, therefore, that give each type of membrane in the cell its ... Many extend through the lipid bilayer, with part of their mass on either side ..... Many hydrophobic membrane proteins can be solubilized and then purified in an active, if not entirely ..... Many Membrane Proteins Diffuse in the Plane of the Membrane.
hope this helps :)
Warning Dont copy all of this i just answered this question to give you idea of what it is

Answer: d. Extracellular matrix was discovered more than 20 years ago.
Explanation:
According to biological sciences, the extracellular matrix is a matrix that consists of three dimensional network of extracellular macromolecules such as enzymes, collagen and glycoproteins which provide structural and biological support for surrounding cells as well.
It is found that it is discovered over 20 years ago in the matrix formed in the mouse EHS sarcoma. Therefore, correct answer is (d).
