Answer:

А.  They belong to the same group of the periodic table.

Explanation:

Two elements possess similar chemical properties if they belong to the same group on the periodic table.

What determines the chemical properties of elements;

→ the number of valence electrons an element contains determines its chemical properties.

  • On the periodic table, groups are vertical arrangement of elements.
  • Periodic groups classifies elements into groups based on the number of valence electrons they contain.
  • So, elements in the same group will have the same number of valence electrons and hence similar chemical properties.

A researcher is carrying out an experiment where she labels a protein with a fluorescent tag (so she can visualize its location
melisa1 [442]

Answer:

The protein likely travels through a common lumen shared by thylakoid membranes and grana, and cannot easily diffuse through the thylakoid membrane.

Explanation:

There is a lot of scientific research in which a specific molecule can be labeled with some fluorescent marker (usually carbon 14). This type of marking allows the researcher to make observations about the movement of these molecules, as you can see in the question above. About the research shown in the question, the researcher realized that the protein labeled with the fluorescent marker moved between the grana and was always in the lumen, so she can conclude that the selocomovement protein moved through the lumen that is shared between the tilacoid membranes and the grana.

Under what environmental conditions would a zygote not undergo meiosis
sashaice [31]

A zygote will not undergo meiosis in an environmental state that is not favorable for the zygote’s survival i.e. the chance of the zygote to survive is not certain. Take for example, chlamydomonas will form a zygote under normal asexual mitotic reproduction in a favorable environmental condition. However, under unfavorable environmental conditions the organism also reproduce sexually to form a zygote but will never proceed to meiotic division because of the unfavorable environmental state.
