Mitochondria and chloroplasts
Grace [21]

Answer:

C. prokaryotic cells

Definitions

The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.

Chloroplast is usually defined as a plastic containing chlorophyll.

Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).  

A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.  

Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

<h2>What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?</h2>

Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.

Why do lipophilic hormones require carrier proteins while being transported in the blood?
valina [46]

Lipophilic hormones, intuitive as the name suggests, tend to dissolve well in lipids/fats than they do in water. Therefore lipophilic hormone does not dissolve well in blood plasma which would affect their diffusion.  The carrier proteins are mainly the serum albumins.

What phase is Homologous chromosome paired.
kumpel [21]

In metaphase I of meiosis I, the pairs of homologous chromosomes, also known as bivalents or tetrads, line up in a random order along the metaphase plate. The random orientation is another way for cells to introduce genetic variation.
