During the light reactions, the pigments and proteins of ____________ use light to send energized electrons through an electron
Nataly [62]

Answer:

The correct answer is - photosystem II; ATP; water; oxygen

Explanation:

The photosynthesis process involves two different cycles known as the light reaction and the dark reaction. In light reaction there are two photosystems; photosystem I and photosystem II.

During light reaction, there are several pigments such as chlorophyll a and other pigments present in photosystem II that trap the light and transfer excited electrons through ETC to produce ATP which is a form of energy used by cells.

A water molecule takes place of the excited electron that is transferred and releases oxygen as waste or byproduct in this reaction.

During meiosis i, assuming no crossing over, what chromatid combination(s) will be present at the completion of prophase i?
arsen [322]

Answer

         Crossing over is the phenomenon in which exchange of chromtids occur between non sister chromatids  and result into recombinant chromatids, which is an important tool for evolution and bring about genetic changes in offsprings as compare to their parents.

No crossing over

                If no crossing over occurs, it means no exchange of chromatids between non sister chromatids of homologous chromosomes, then no recombinant chromatids will be formed.

Result

        At the end of meiosis II, when four haploid cells are formed, all these cell will contain similar chromosomes as present in parent. Thus chromosomes are non recombinant because of no crossing over.

(01.04 mc)water at about 4°c (39°f) is more dense than water at 0°c (32°f). why would the living organisms in the lake die if th
makkiz [27]
Didn't you say that the water at 39 degrees is more dense than water at its freezing point? I think the reason organisms would die is because the water already starting to structure in a crystal form, when it starts to freeze into ice. This probably why it kills the organisms, is because the water ceases to allow the organism to function at those temperatures.
