What will happen to ATP production when the electron transport chain is disabled? Explain your answer.
Tanya [424]
It would be decreased significantly. The ETC makes 28 molecules of ATP so if it is disabled then you would only get your net gain of 2 ATP from glycolysis

Intramembranous ossification begins with differentiation of ________ cells.
PIT_PIT [208]

Answer:

Intramembranous ossification begins with differentiation of mesenchymal  cells.

Explanation:

Fibrous membranes are involved in the development of the bones. The process through which this occurs is termed as the intramembranous ossification.

The cells of the mesenchyma begin to split. These cells differentiate into specialized cells each performing different functions. The following bones are formed by the process of intramembranous ossification:

  • mandible
  • clavicle
  • some bones of the skull

Two genes determining a trait In primroses, the dominant allele of gene K is necessary to synthesize blue flower pigment. Blue p
GREYUIT [131]

Answer:

The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

Explanation:

<u>Available data:</u>

  • The dominant allele K is necessary to synthesize blue flower pigment
  • K is inhibited by the dominant allele D
  • Plants with the genotype K- D- will not produce pigment (and their flowers will be white)

Cross: testcross for (Kk Dd) plants

Parental)   KkDd     x     kkdd

Gametes) KD   kD   Kd   kd      

                kd   kd   kd   kd

Punnet square)        KD        Kd       kD       kd

                      kd     KkDd   Kkdd   kkDd   kkdd

                      kd     KkDd  Kkdd   kkDd   kkdd

                      kd     KkDd   Kkdd   kkDd   kkdd

                      kd     KkDd   Kkdd   kkDd   kkdd

  • Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
  • Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
  • The recessive form for K and D genes will express white-flowered plants, with genotype ddkk

F1) Progeny genotype: 4/16 KkDd, white-flowered plants

                                      4/16 Kkdd, blue-flowered plants

                                      4/16 kkDd, white-flowered plants

                                      4/16 kkdd, white-flowered plants

     The ratio of blue to white offspring in the progeny is 4 blue : 12 white.

     Blue-flowered plants: 4 Kkdd

     White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd

Do you think lava could have formed the channel on Mars? Why or why not?
shtirl [24]

Answer:

maybe but not probable

Explanation:

Larger image Flowing lava can carve or build paths very much like the riverbeds and canyons etched by water, and this probably explains at least one of the meandering channels on the surface of Mars. ... Lava is generally not thought to be able to create such finely crafted features.
