Answer:

Sexual reproduction helps to increase..=genetic diversity within a species and evolutionary advancements

The advantage of asexual reproduction is=large number of offspring identical to parent,no need to waste energy to find a mate

Hope this helps!

Salvesen h, piehl-aulin k, ljunghall s. changes in levels of the carboxyterminal propeptide of type i procollagen, the carboxyte
Dennis_Churaev [7]
Physical exercise preserves bone mass. Measurements of bone biomarkers may reflect the events in bone during exercise. Fifteen healthy, well-trained individuals (7 men and 8 women) performed a running test for 21 min until exhaustion. Venous blood samples were drawn before and 30 min after the exercise to measure the levels of osteocalcin, the carboxyterminal propeptide of type I procollagen (PICP) and the carboxyterminal cross-linked telopeptide of type I collagen (ICTP). After exercise, the women had a marked increase in serum osteocalcin concentrations (from 7.5±5.0 μg/1 to 11.5±3.0 μg/1), whereas the level was unaffected in the men (from 14.5±3.0 μg/1 to 13.5±4.6 μg/l). In the men there was a marked increase in PICP (from 240±47 μg/1 to 268±56 μg/1) that was not seen in the women (from 244±70 μg/1 to 253±60 μg/1). In neither group did ICTP levels change. In conclusion, significant responses were seen in PICP and osteocalcin during exercise, indicating that such measurements may be valuable for the further delineation of the effects of physical activity on bone. Furthermore, the different responses in men and women point to interesting areas for future studies.

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.
