Answer:
Water has the property of cohesion and adhesion. Cohesion provides the property of water to get attached with other water molecules and it holds water molecules together, adherence provides the property of stickiness to any surface to the water molecule.
These two properties together allow water molecules to move upwards against gravity. Water moves by capillary action through the water column. Cohesion and adhesion create a pull on the column which transport the water towards the leaves from where they get evaporated.
This evaporation then causes tension on another water molecule and this tension then pulls another water molecule towards leaves.
The pattern of embryonic development in which only the cells lacking yolk subsequently undergo cleavage is called meroblastic development, which is typical of birds.
Therefore, the correct answer is Option D.
<h3>What is embryonic cleavage?</h3>
- Embryonic cleavage is the division of cells which occurs just after fertilization and are involved in the early development of the embryo.
- The different cells formed after cleavage are called the blastomeres and these are present in a compact mass called the morula.
- The end product of cleavage is blastula which is a hollow sphere with a cavity called blastocoel.
- Cleavage can be of different types depending upon the concentration of yolk in the egg as yolk does not undergo cell division.
- In holoblastic cleavage, the entire egg divides as yolk is present in very less concentration.
- In meroblastic cleavage, only the cells lacking yolk divide.

They are energy production, energy storage, building macromolecules, sparing protein, and assisting in lipid metabolism
hope this helps :)
Answer:ATP is required for muscle contraction. Four sources of this substance are available to muscle fibers: free ATP, phosphocreatine, glycolysis and cellular respiration. A small amount of free ATP is available in the muscle for immediate use
Explanation:
Answer:
cell membrane
Explanation
It's the outer living boundary of animal cells. It's made of lipid and protein. Plasma Membrane is a mosaic of phospholipids, cholesterol, and proteins, the proteins in plasma membrane regulates the coming/going of substances into/out of the cell.
