Somatic mutation, genetic alteration acquired by a cell that can be passed to the progeny of the mutated cell in the course of cell division. Somatic mutations differ from germ line mutations, which are inherited genetic alterations that occur in the germ cells (i.e., sperm and eggs).
Answer;
Without the keystone species, the rocky inter-tidal ecosystem would be dramatically different or cease to exist altogether
Explanation;
Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.
For instance; the starfish Pisaster ochraceus is a keystone species in the rocky marine inter-tidal communities off the northwest coast of North America. It feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities.
The eye spot of euglena is to detect the intensity of light.
<h3>COMPONENTS OF EUGLENA:</h3>
Euglena is a protist that possesses the characteristics of plant and animal. It is a unicellular and microscopic organism.
Euglena possesses certain structures that serve different purposes in the cell. They include:
- Gullet
- Eye spot or stigma
- Chloroplast
- Pellicle
Therefore, the eye spot as a structure is used to detect the intensity of light.

The nucleic acid sequences are complementary and parallel, but they go in opposite directions, hence the antiparallel designation. The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way.
False.
Explanation:
Human heart is four chambered with one auricle and one ventricle on each side.The auricles are the receiving chambers and ventricles are the distributing chambers.
The right side of the heart contains de-oxygenated blood and pumps the blood to the lungs and is known as pulmonary circuit pump.
The left side of the heart receives oxygenated blood from lungs and pumps it to the body. It is referred to as systemic circuit pump.
