Answer:
The elements in increasing order of atomic radius: oxygen, carbon, aluminum, potassium
Explanation:
The distance from the center of the nucleus to the outermost shell of the electron is known as the atomic radius of an element. The atomic radius decreases rightward along each period (row) of the table due to the increase in effective nuclear charge (the charge of the nucleus equal to the number of protons). Across a period, electrons are added to the same energy level and the increasing number of protons causes the nucleus to exert more pull on these electrons, which makes the atomic radius smaller. Atomic radius increases down each group (column) of the periodic table because of the addition of electrons to higher energy levels, which are further away from the nucleus and the pull of nucleus weakens. Another reason for the increase in atomic radius is the electron shielding effect, which is the reduction of the attractive force between a nucleus and its outer electrons due to the blocking effect of inner electrons
While moving from left to right in the second period, c
arbon comes before oxygen and so oxygen will have a smaller atomic radius than carbon. While moving down the periodic table, al
uminum comes before potassium even if they are not in the same period. So aluminum
's atomic radius will be smaller than that of potassium but bigger than that of carbon and oxygen.

Answer:
Connective Tissues
Explanation:
According to my research on studies conducted by various medical professions, I can say that based on the information provided within the question this scientist is most likely looking at Connective Tissues. These are tissues in which material secreted by the cells is fills up the spaces between the cells, thus connecting or binding otherwise separate tissues or organs. Which is what the scientist seems to be describing.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer:
not 100% sure but
Explanation:
might be because each fruit fly has a different eye color because offspring from parents will have different eye color. or it might be from some sort of mutation that happened, that might be why they still have the gene to orange eyes. or red eyed fruit flys(or fly) migrated into a orange eyed populating and had offspring like that, that would also explain why red eyed fruit flys have the orange eyed gene.
again not 100% sure
but I hoped it helped a little
More nitrogen in the atmosphere leads to NITRIC ACID RAIN.
When nitrogenous fertilizers are used on the farm, some gases are released into the atmosphere including nitric oxide. These gases rises up into the atmosphere, mix with rainfall.
Nitric oxide react with rainfall to form nitric acid and it falls as acidic rain.
