Answer:
Thus, the minimum number of photons per second is 77.34
Explanation:
Light intensity,
= 
Pupil has a diameter, d = 8.5 mm
= 8.5 x
m
Radius of the eye, r = 4.25 x
m
∴ Area of the eye, A = 
= 
= 
Let
be the minimum number of photons.
Therefore,
=
x A
=
x 
=
W
Thus the minimum number of photons is given by

where E = 
= 
= 
Therefore,
= 
= 77.34 photons per second
Thus, the minimum number of photons per second is 77.34
The hormone produced by the placenta that stimulates the ovaries to continue producing estrogen and progesterone is called the follicle stimulating hormone. This hormone stimulates the ovarian follicle allowing the egg to grow thus producing continuous supply of estrogen and progesterone.
Hey could you send the picture of what it is, I might could help.
Answer:
a) The substrate 2 will be accumulated in the cells.
b) The enzyme E is mutated
Explanation:
a) The enzyme C has a mutation, the substrate 2 will not be turn into substrate 3 and this will cause to accumulation of 2.
b) when cells have 1,2,3 or 4 because of mutation of E non of these substrates cannot lead to 5. but ıf 5 gıven from the diet, the individuals can survive.
Answer:
Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.
Explanation:
Options for this question are:
- <em>They both lack a nucleus and contain cytoplasm.
</em>
- <em>The unique functional adaptations of Archaea are more similar to Eukarya adaptations. </em>
- <em>
They both evolved in the same geological time period.
</em>
- <em>
</em><em>Genetically, the Archaea are more similar to Eukarya than Bacteria.
</em>
- <em>
They both have membrane-bound organelles.
</em>
- <em>
Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.</em>
Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.
The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.
