The answer of the first question is double fertilization !!! I don't get the second question so.... comment if you have that question !!!
Ganymede & Callisto are low-density moons with a mixture of ice and rock. They are farther from Jupiter and are geologically dead.
The four largest moons of Jupiter, Io, Europa, Ganymede, and Callisto, are known as the Galilean moons or Galilean satellites. Galileo Galilei initially observed them in December 1609 or January 1610, and in March 1610, he identified them as Jupiter satellites. They were the first discovered extraterrestrial objects orbiting a planet other than the Earth.

<u>Chemical bonds between glucose molecules in starch that are easily broken by human </u><u>digestive enzymes </u><u>are called</u><u> alpha bonds.</u>
How is starch broken down into glucose?
- When you consume starchy meals, an enzyme called amylase located in your saliva and small intestine breaks down the starches into sugars like glucose, maltotriose, and maltose.
- Other enzymes, such as maltase, lactase, sucrase, and isomaltase, further break down these compound sugars into simple sugars.
What is alpha and beta bond?
- The 1,4 alpha and 1,4 beta glycosidic linkages are the two different forms of glycosidic bonds.
- When the OH on the carbon-1 is below the glucose ring, 1,4 alpha glycosidic bonds are created, whereas when the OH is above the plane, 1,4 beta glycosidic bonds are created.

Answer:
The correct answer is carbohydrate chain.
Explanation:
Plasma membrane contain three types of protein a peripheral protein b transmembrane protein and c GPI anchored protein.
Some membrane protein basically peripheral proteins contain oligosaccharide chain arranged towards the extracellular region of the plasma membrane with respect to the surface of that glycoprotein.
The oligosaccharide chain of glycoprotein play an important role in to identify signals from outside the cell.These signals may include the entry of virus particles inside our body,protein targeting etc.
Answer:
Plants need a rigid structure. Animal cells have flexible cell membranes. So animal cells can have a variety of shapes, but plant cells can not, they have to take the shape of their cell walls. Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.
