Those would be enzymes I believe. They are the power house of the membrane and lower the amount of activation energy needed.
Solution:
The most appropiate unit of measurement fro most types of cells is CD4 counts are measured in cells per cubic millimetre = cells/mm3. A cubic millimetre (mm3) = mm3 = 1 mm x 1 mm x 1 mm.
This is the required answer.
If a plant just did photosynthesis then the plant would not have any food and just an abundant amount of ATP. they use cellular respiration to make food they can use to grow
the energy source is primarily the sun, and it drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil.
Macroevolution can cause significant changes in the frequencies of alleles, that can ultimately result in speciation (forming of new species).
Various large-scale events like climate change and continental drift can greatly influence the distribution of species and adaptive radiation of different groups that can fill vacant ecological niches.
The changes in gene regulation and genetic mutations can also contribute to macroevolution by producing novel traits and adaptations.
