Answer:

Light energy absorbed by pigments produces high-energy electrons that are used to convert NADP+ ( a coenzyme that functions as a universal electron carrier, accepting electrons and hydrogen atoms to form NADPH) and ADP ( adenosine diphosphate which helps in formation of the energy) to the compounds NADPH and ATP (energy), trapping the energy in chemical form.

Explanation:

During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP. The third phosphate chemical bond contains the new chemical energy.

What organelle converts molecules from the food you eat into usable energy?

Vanyuwa [196]

I believe the correct answer would be the mitochondrion

The food we eat is processed into glucose, and then converted into ATP - usable energy by the mitochondrion

The mitochondria is the powerhouse of the cell

I hope this helped!

If a species currently alive today were undergoing intense diversifying selection, which of the following might you expect to se

jenyasd209 [6]

<span>Separate populations of the species with distinctive profiles, perhaps even the start of speciation, or multiple species descended from the original one.
This is because it's diversifying, with many different traits changing.</span>

Answer:

Yes, P. Falciparum and T. Cruzi undergo similar antigenic variation because of repetitive genomes evolved by time.

Explanation:

Living (i.e., actively proliferating) repeats are dynamic elements which reshape their host genomes by generating rearrangements, creating and destroying genes, shuffling existing genes, and modulating patterns of expression. Dead repeats (i.e., those which are no longer able to proliferate) constitute a palaeontological record, which can be mined for clues about evolutionary events and impetus. The dynamic nature of repeats leads to a rapid evolutionary divergence that can be used in species identification and phylogenetic inference. Repeats can also provide passive markers for studying processes of mutation and selection.

The genomes of these protozoan parasites, like all eukaryotic genomes, have been colonized by diverse repetitive elements. Repetitive sequences can be artificially divided into two groups: interspersed repeats and tandemly repeated DNA. P. falciparum undergoes antigenic variation ans similar anitgenic variation is present in t. cruzi because of repetitive sequences resembling each other.
