Answer:
Molecules which move against the concentration gradient across the cell membrane employ the mechanism of active transportation.
Explanation:
Normally, permitted molecules moves across the cell membrane of the cell by the process of diffusion and osmosis. This is used when molecules move from hypertonic region to hypotonic region (if ions) and hypotonic to hypertonic (if water). This is a passive transportation which do not require the expense of energy from the cell.
In contrast, when molecules move in or out of the cell against their concentration gradient, that is ions moving from hypotonic region to hypertonic region, they implore the expense of energy in form of adenosine triphosphate (ATP), and the involvement of the membrane carrier proteins. This is called active transport.
<u>Answer</u>:
Organic molecules present in chicken are Nucleic acid, proteins, carbohydrate and lipids
.
<u>Explanation</u>:
Chicken itself has the all four organic molecules in it. Organic molecules are those having carbon in it. They are attached by covalent bonds, in which electrons are being shared within the atoms. The nucleic acids are DNA and RNA which helps in the making of the proteins which are found in the various structure and ought to perform various metabolic functions. Proteins are the building block of the amino acids. Lipids found are the fat bodies, burning of lipids gives us energy.
Long eyelashes is the dominant trait because, in the last sentence, donna mentioned how nearly everyone in the family had long eyelashes, while barbara and her had short ones. this proves that long eyelashes are much more common in the family than short eyelashes, which means long eyelashes would be dominant, while short eyelashes would be recessive.
Vance is demonstrating conceptual knowledge
Conceptual knowledge is the clear and detailed understanding of principles, concepts, models or theories and the understanding of the linking relationships between them. Conceptual knowledge is acquired by thoughtful, reflective learning, listening, reading, or viewing. From the question, Vance is demonstrating conceptual knowledge because he has the explicit understanding of why rainfall amounts affect different types of vegetation positively and others negatively.
