Answer:
viviparous animals like birds have a disadvantage compare to viviparous animals like mammals (humans) because the mammal embryo will have a steady supply of nutrients throughout its development through the umbilical cord. The egg needs to have all the necessary nutrients to shape the organism.
The egg yolk along with the egg white supply the "raw materials" necessary for the embryo development.
Protein is used to make structural component like muscles and bones also enzymes are a type of protein.
Fats and cholesterol provide energy. Cell membranes are phospholipid bi-layers. Lipids are fats hence the need for them. Some hormones also contain protein and lipids.
A. geographic range because there is a range of area where a species can thrive but after you reach a certain point the climate and environment changes and species will no longer be able to withstand it. Climate, weather, and sometimes habitat would all be considered abiotic factors.
The correct answer is cohesion and adhesion.
The cohesion of the water means that the H₂0 molecules are attracted by other H₂O molecules (molecules of the same kind are attracted). Adhesion is the attraction of molecules of different kinds. <span>Water moving up a straw is an example of the motion of water against gravity which depends on the attraction between water molecules and the walls of the straw (adhesion), and also on the attraction between water molecules (cohesion).</span>
Butter is mostly fat, A chicken bone is mostly calcium, and meat does not have a compostable composition.
Answer:
Active transport
Explanation:
Active transport requires energy from the cell. It occurs when substances move from areas of lower to higher concentration or when very large molecules are transported. Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis.
