Answer:
F1 and F2 Generations
The offspring of the P generation are called the F1 (for filial, or “offspring”) generation.
Answer:
popcorn kernels aren't living things
Explanation:
characteristics they have that show proof they are living organisms:
• movement when exposed to heat
• irritability/sensitivity since they react to change of temperature
• growth since when they are exposed to high temperatures they grow and become bigger
We can determine if they are living or not by:
• seeing if they respire
• seeing if they need nourishment
• seeing if they can excrete
• seeing if they can reproduce
In conclusion they aren't living things
Answer:
as I know
Explanation:
<em>Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils. The “soft” tissues of an organism, such as skin, muscles, and internal organs are typically not preserved as fossils.</em>

Answer:
A. NADH and FADH2 both donate electrons at the same location.
Explanation:
In the respiratory chain, four large protein complexes inserted into the mitochondrial inner membrane transport NADH and FADH₂ electrons (formed in glycolysis and the Krebs cycle) to oxygen gas, reducing them to NAD⁺ and FAD, respectively.
These electrons have great affinity for oxygen gas and, when combined with it, reduce it to water molecules at the end of the reaction.
Oxygen gas effectively participates in cellular respiration at this stage, so its absence would imply interruption of the process.
NADH and FADH₂ electrons, when attracted to oxygen, travel a path through protein complexes, releasing energy in this process.
The energy released by the NADH and FADH₂ electrons in the respiratory chain in theory yields <u>34</u> <u>ATP</u>, however, under normal conditions an average of 26 ATP molecules is formed.
If we consider that these 26 molecules are added to the two ATP formed in glycolysis and two ATP formed in the Krebs cycle, it can be said that cellular respiration reaches a maximum yield of 30 ATP per glucose molecule, although theoretically this number was 38 ATP per glucose molecule.
