Answer:

The correct answer would be four limbs.

Explanation:

The cladogram or branching tree displaying different characters shared by the different animals. This cladogram shares the character four limbs by all of the organisms in this from amphibians to up to cats.

Amphibians, reptiles, marsupials, dogs, and cats all have four limbs and this character is evolved at the beginning.

Thus, the correct answer would be four limbs.

You are given a flask with standard liquid media containing a population of S. pombe cells that have a temperature sensitive mut
Ne4ueva [31]

Answer:

The best graphic that represent the growth of the cells is the plot #2

Explanation:

Using flow cytometry, a cell cycle analysis study uses a dye for DNA binding, and it is fluorescently labeled to allow stoichiometry of DNA to bind to DNA content.

During the phases, the DNA content will be:

G0 / G1 phase = 2n (diploid).

Phase S = 2n (duplication of DNA content)

G2 / M phase = 4n (content of tetraploid DNA 4n)

When cells are growing, a mutation will occur in the gene. This would lead to the cell cycle being unlikely to stop due to the checkpoint gene mutation, causing it to be unable to detect any damage. the cell cycle continues normally.

In exercise, cells that were in the G1 phase will reach the S phase. Therefore, the peak of that phase will be increased, and the peak of the G1 phase will decrease. The cells that were in the S phase will go to the G2 / M phase, which will increase the peak.

The light independent reactions produce ______________ and _______________ which are used in the light dependent reactions. A) N
Elan Coil [88]

The light dependent reaction produces B NADPH and ATP which are used in the light independent reaction or dark reaction.

Explanation:

Light dependent reaction also called light reaction occur in the thylakoid of grana. Light dependent reaction leads to the generate ATP and NADPH.

  Role of ATP

ATP is an energy rich compound which undergo hydrolysis to generate huge amount of free energy. ATP is formed in the cyclic photo phosphorylation by the transport of electron through various electron carrier leading to generate energy for the phosphorylation of ADP into ATP.

Role of NADPH

NADPH act as reducing agent which is formed as the end product of noncyclic photo phosphorylation.NADPH helps in the reduction of Phosphoglyceric acid(PGA) into Phosphoglyceraldehyde(PGALD). The so formed PGALD undergo further reacts to generate glucose and also to regenerate Ribulose bisphosphate(RUBP).
