Hey there :)
All the options you have given are applicable.
Because xylem and phloem are essentials as they are the veins of the leaves. They are bundled together in thin strands. They allow the movement of water and nutrients.
The veins of leaves are finely branched to be in close contact with photosynthesizing cells as they need to store food.
I believe it's RNA. But double check that please.
Answer;
Arrangement of events in stellar formation;
C) The Big Bang occurs.
B) Pockets of elements in higher concentrations begin experiencing greater gravitational force.
A) Hydrogen atoms shed their electrons and fuse together to form larger helium atoms.
D) the glass clouds begin reducing in volume, which leads to increase in density, pressure, and temperature.
Explanation;
-Stellar evolution is the process by which a star changes over the course of time. All stars are born from collapsing clouds of gas and dust, often called nebulae or molecular clouds.
-Stars are born out of the gravitational collapse of cool, dense molecular clouds. As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores.
Answer:
that would be a phenotype
<span>The experimental evidence that leads </span><span>scientists to believe that only quantized electronic energy states exist in atoms </span>was the Niels Bohr experiment on Hydrogen gas. The quantized model for electron orbits in atoms that effectively explained the spectroscopic behavior of the atoms. Each line in the spectrum corresponds to one exact frequency of light emitted by the atom.
