Even when they are not using an electron transport chain (ETC), fermenting bacteria need a proton motive force (PMF) for transport processes.

The proton motive force (PMF) is an electrochemical gradient of protons that bacteria produce and sustain across their cytoplasmic membrane. Numerous crucial bacterial functions, including ATP production, flagellar motility, and transport processes, depend on this PMF. Proton motive force (PMF) is a fundamental component of all bacterial growth and survival in both replicating and non-replicating environments. Energy is conserved during respiration by producing PMF across a proton-impermeable barrier.

Answer No 1:

Process 1 is cellular respiration. Cellular respiration can be described as a process in which glucose and oxygen are converted into water and carbon dioxide. ATP is released by this process which is used as an energy source.

Process 2 is anaerobic respiration. It is a process which occurs in the absence  of oxygen. This process will also yield ATP.

Answer No 2:

The process 1, cellular respiration, is known to produce 38 molecules of ATP. Out of these, 2 molecules are the result from the process of glycolysis, 2 molecules arise from Kreb's cycle, rest 34 are known to occur from the electron transport chain.

The process of anaerobic respiration is known to make 2 molecules of ATP in total.

m_a_m_a [10]

Answer:

12 : 3 : 1

Explanation:

According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and  1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.

<em>Dihybrid cross for heterozygous summer squash:</em>

                    WG         Wg            wG            wg          

    WG      WWGG   WWGg     WwGG     WwGg

    Wg       WWGg   WWgg     WwGg      Wwgg

    wG        WwGG    WwGg     wwGG      wwGg

      wg       WwGg    Wwgg     wwGg        wwgg

   Genotypes:

   W-G-  and W- gg  = white = 12

    ww G- = yellow = 3

     ww gg = green = 1

vazorg [7]

Answer:

b.

Explanation:

Based on the information provided within the question it can be said that from this info the researcher can conclude that Dandelion seed number is a constitutive defensive response to rabbit herbivory. This is mainly due to the fact that Dandelions that have been eaten by the rabbits have produced more seeds, meaning that the Dandelions defense mechanism produces more seeds when attacked in order to prevent the flower's extinction.
