Answer:
- Increasing uncontrolled poaching acts as some kind of <em>"selective pressure"</em>.
- Animals that carry the genes to grow tusks are removed from the population, and most of the surviving animals are those that do not have tusk and that carry the gene for tusklessness.
- Tuskless animals get to reproduce more frequently, transmitting the tusklessness gene to their progeny, and hence, increasing its frequency in the population.

Answer:
Xylem cells have no cytoplasm or end walls, meaning they form a tube through which water can pass freely to allow water transport. Lignin strengthens the cell walls, helping to support the plant.
Explanation:
it is the tendency relatively stable equilibrium between interdependent elements especially as maintained by physiological processes.
C. Commensalism
"An association between two organisms in which one benefits and the other derives neither benefit nor harm."
A translocation that moves a gene from an area of euchromatin to heterochromatin would typically cause a(n) reduction in the expression of the gene.
<h3>What is euchromatin?</h3>
- A kind of chromatin that is sparsely packed, enriched in genes, and frequently engaged in transcription is called euchromatin.
- Contrasting with heterochromatin, which is compact and less accessible for transcription, is euchromatin.
- The human genome has 92% euchromatic DNA.
<h3>What is heterochromatin?</h3>
- Heterochromatin, often known as condensed DNA or densely packed DNA, has many different types.
- Between constitutive heterochromatin and facultative heterochromatin, these variations fall on a spectrum. Both contribute to how genes are expressed.
- Eukaryotic genomes contain heterochromatin, which serves a variety of purposes including regulating gene expression and preventing DNA replication and repair.
