What seems to be a major difference between a deciduous forest and a coniferous forest
Vera_Pavlovna [14]

Answer:

Explanation:

Coniferous means 'cone bearing,' meaning these trees don't lose their leaves every year. Deciduous means 'falling off' so those trees lose their leaves every year. I would assume the difference is that coniferous forests don't lose their leaves every year while deciduous forests do.

Which genetic variation is shown below?
Leno4ka [110]

Answer:

This Punnett square shows<u> incomplete dominance.</u>

Explanation:

The homozygous red flower has two dominant red alleles, and these are represented by the letters RR. The homozygous white flower is represented by rr. Their offspring are all heterozygous Rr, and they have pink flowers. This is the first filial generation, or F1. When the F1 generation cross-pollinates, their offspring will be RR, Rr, and rr in a 1:2:1 ratio. Some of their offspring (the F2 generation) will inherit two R alleles, some will inherit two r alleles, and some will inherit both.

Hope this help

In the electron transport system
antoniya [11.8K]

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.
