Answer:
Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. ... A molecule is a chemical structure consisting of at least two atoms held together by one or more chemical bonds.
Explanation:
The answer is C. Thermal energy is transferred to her face by radiation, and thermal energy is transferred to the bottoms of her feet by conduction.
Conduction is a method of transferring heat by using the collision of molecules and free electrons (depending on the material). Heat is usually transferred by conduction if both objects are in contact with each other that way the molecules can collide and spread the kinetic energy thus raising their internal heat. So, since the feet and the sand are in contact, so the heat should be transferred by conduction. However, air is a very poor heat conductor, it cannot transfer heat efficiently, therefore, the first answer is not conduction.
Radiation is a method of transferring heat too but using electromagnetic waves. It works great even in the air, or even with vacuum space. The sun shining from outer space to earth through the vacuum space is also by radiation. So, the first answer is radiation.
The answer is C, hope it helps!
Answer:
A) Ice cream starts dripping down the sides of an ice cream cone: melting
B) Fog is created by using dry ice: sublimation
C) Frost forms on trees on a very cold day: deposition
D) The mirror gets fogged up when you breathe on it: condensation
E) Your wet hair dries after a few minutes: evaporation
F) Liquid glass cools and hardens : freezing
Explanation:
Sublimation process where solid state changes to gaseous state by escaping liquid state.
Deposition process where gaseous state changes to solid state by escaping liquid state.
Condensation process where gaseous state changes to liquid state.
Melting is the process where solid state changes to liquid state.
Evaporation process is a process where liquid state changes to gaseous state.
Freezing is the process in which liquid changes to solid state.
Gametes are the genetically different kind of cells which are produced as a result of meiosis. Meiosis is a reductional division in which the chromosomes are reduced to half. Genetic variation in the gametes is due to crossing over between two non-sister chromatids of a homologous chromosomes during meiosis.
Answer:
The correct answer is A. Substrate-level phosphorylation
Explanation:
During the substrate-level phosphorylation, phosphoryl group is directly added to ADP or GDP to form ATP or GTP from phosphorylated intermediate rather than from inorganic phosphate like in case of oxidative phosphorylation.
So in glycolysis 4 ATP are produced by substrate-level phosphorylation. Apart from the 4 ATP, 2NADH are also produced during the glycolysis which is used during the oxidative phosphorylation and produce 4-6 ATP.
So ATP made during glycolysis is generated by substrate-level phosphorylation as ATP is produced by direct addition of phosphoryl group from intermediates.
