Can organisms express a trait that they do not have the code for in their genes?

1 answer:

4 0

They must have the code in their genes in order to express it and they can have the code but not express the trait depending on the regulatory mechanisms which determine if the genes are turned on or off

In chloroplasts, when the two photosystems work in series, electrons ejected from the photosystems do not return to them, which

cricket20 [7]

When electrons do not return to the photosystems, it is because of a process known as oxygenic photophosphorylation, a process that is key to photosynthesis.

Photosynthesis is the process by which plants get their energy. This process involves many steps taken in order to turn energy from light, into sugar and molecular energy known as ATP, needed for plants to survive. This process uses a variety of important and complex steps, among which is included oxygenic photophosphorylation.

Oxygenic photophosphorylation is one of the key processes to photosynthesis. It involves the use of photosystems <u>one </u>and <u>three</u>, located in the thylakoid membrane of plant cells, in order to produce NADPH and ATP. These systems enter a state of photoactivation, releasing an electron to be carried by the NADPH molecule towards the Calvin cycle where the electron can be placed onto a carbon atom, for long-term storage, often as a carbohydrate.

A hypertonic solution has:

BaLLatris [955]

A hypertonic solution has:

Fewer water molecules outside the cell than are inside the cell. Thus, option "A" is correct.

<h3>What is hypertonic solution?</h3>

The cell is in a hypertonic solution because it lost water through osmosis and shrunk.
A hypertonic solution contains more solute molecules compared to solvent molecules while the hypotonic solution has more solvent molecules than solute molecules.
When a plant cell is placed in a hypertonic solution it loses water through osmosis and shrinks.
An animal cell placed in a hypotonic solution absorbs water through osmosis, increases in size and then bursts. Plant cell, on the other hand, does not burst when placed in a hypotonic solution as it contains a cellulose cell wall.

Thus, option "A" is correct.

give an example of what the failure on an organ have on other organ systems? pls write your answer short! Thanks in advance!

devlian [24]

Hey this is late, but if an organ fails, like for example the kidney fails right? So then it affects the heart. and so on, because the kidney helps clean the blood and your body needs blood.
