The effects of anaerobic conditions how would anaerobic conditions (when no o2 is present) affect the rate of electron transport
Romashka-Z-Leto [24]
Anaerobic condition refers to an environmental condition where oxygen is absent. In case of Electron Transport System (ETS) and ATP production, oxygen acts as the final acceptor of electrons. As oxygen is a reactant in ETS and ATP production, unavailability of oxygen can cause no oxidation of the coenzymes or the carriers such as NAPH and FADH2 and no ATP will be produced. Thus, both Electron Transport System and ATP production will stop in the absence of oxygen.

What is the function of the mini-valves in lymph capillaries?
Naya [18.7K]

 They increase the permeability of the lymph capillaries. Interstitial fluid enters the lymphatic vessels through the mini valves (which are overlaps of endothelial cells from multiple lymph capillaries). The valves also prevent the backflow of the lymph from the vessels back to the tissues.

Suppose that in another world, DNA does not undergo semiconservative replication, but instead a conservative mechanism is used.
Liono4ka [1.6K]

Answer:

c. ¼ heavy, ¾ light

Explanation:

DNA replication follows semi conservative model which means that both the strands separate during replication and the newly formed DNA molecule has one old and one new strand. If instead of semi conservative, conservative mechanism is used, old strands will not separate from each other and the two newly synthesised DNA strands will come together to form a DNA molecule.

Here the cells were first grown in heavy 15N medium so all the DNA molecules had 15N and thus were heavy. Then the cells were transferred to 14N medium where only lighter 14N were available for replication process.

In first generation, 14N DNA molecules were synthesised from 15N DNA molecules so 1/2 DNA molecules were 15N and other half were 14N. In the second generation, 14N molecules will give rise to new 14N molecules and 15N molecules will also give rise to 14N molecules hence 1/4 molecules will be 15N (heavy) and 3/4 will be 14N (light).

Is the escape of a rattlesnake from a zoo exhibit an example of an invasive species?
Brums [2.3K]

Answer:

No, it isn't

Explanation:

An invasive species is characterized by an organism's appearance in an area it is not a native of, with a high capacity of reproduction that will cause it to be a threat to native species in that area. A species of organism is tagged "invasive" if it is foreign to a region/location and possess a high reproductive rate that spreads fast and causes harm to other species.

Based on the analogy given in this question about the escape of a rattlesnake from a zoo, it cannot be ascertained that it is an example of invasive species. This is because rattlesnakes may be native to that area and possess a zero threat level to the environment in terms of high spreading rate.
