Answer:
<em>What role did endosymbiosis play in the evolution of eukaryotes? Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. This kind of natural selection led to the evolution of eukaryotic cells and the plants and animals we see today.</em>
Explanation:
<em>Endosymbiosis is important because it is a theory that explains the origin of chloroplast and mitochondria. It is also a theory that explains how eukaryotic cells came to be. DNA, RNA, Ribosomes and Protein Synthesis
</em>
<em>
</em>
<em>This provided the first substantial evidence for the endosymbiotic hypothesis. It was also determined that mitochondria and chloroplasts divide independently of the cell they live in.</em>
Answer:
- 100% of the girls are expected to be normal, X+X+ and X+X-
- 50% of the boys are expected to be normal, X+Y
- 50% of the boys are expected to be hemophilic, X-Y
- 75% of the whole offspring normal (X+X+, X+X-, X+Y)
- 25% of the whole offspring hemophilic (X-Y)

There are four types of sensory receptors that respond to one of the four primary stimuli.
Thermoreceptors detect temperature changes in the environment.
Mechanoreceptors detect changes in pressure
Photoreceptors detect the photons composing light
Chemoreceptors detect chemical stimuli and are found inside the body (for example blood vessels). They are also responsible for our sense of taste and smell.
Thus, the correct answer to the question is D. on the tongue and in the nose, to detect taste or odor.
Answer:
A nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials, such as nucleic acids and proteins, between the nucleus and cytoplasm.
