The first statement is wrong because photosynthesis occur during day by plants, while respiration happens during day and night which are very related and they can be happened at the same time, in other hand photosynthesis cannot Accor in human cells because animal cells do not have chloroplasts which are using light energy to make glucose ,but in our cells or in animal cells we have mitochondria which break down the energy to make ATP....
for the second statement I'm not sure about that ....
I think that the third statement Is correct, because
the Cellular respiration make carbon dioxide + water + ATP then those would be then used by photosynthesis to make glucose and oxygen .
can I get brainlist pls?
Edwin Hubble's observation of galaxies revealed that the light received from them were red-shifted, indicating that they are moving away from us. And the seemingly farther away a galaxy was, the greater its red-shift. This can only be explained if a all the galaxies were expanding outward. Determining the exact distances to the other galaxies was a problem, however, until the Hubble space telescope. It had high enough resolution to identify Cepheid variable stars in other galaxies, and accurately determine their distance, and therefore the expansion rate of the universe. Hope this helps!!
I think you got it right
But I’m but sure
Taxonomy can be defined as science of naming, describing and
classifying orgainisms. In 1707-1778, Swedish botanist named Carolus Linneaus developed a
modern taxonomic system and the statement that describes the modern
taxonomy of organism is that “Organism physical characteristics can be used to
differentiate and identify different species and this factor is based on their
genetics".
