3. The sperm is produced inside the scrotum and stored in the e<span>pididymis. During ejaculation, the sperm flows through the Vas deferens and the ejaculatory duct before reaching the urethra. The urethra is the tube inside the penis that ends in the preputial orifice or the hole at the tip of the penis where the sperm flows out.</span>

Whether during mitosis or meiosis, sister chromatids are held together by proteins referred to as cohesions. Such molecules must
scoundrel [369]

Answer:

1. They must be removed before sister chromatids or homologous chromosomes can separate

Explanation:

During the S-phase of the cell cycle, not only does DNA have to be replicated, but also newly synthesized DNA molecules have to be connected with each other. This replicated DNA (sister chromatids) remain physically connected with each other from S phase until metaphase. This physical connection is called Sister chromatids cohesion.

Sister chromatid cohesion depends on COHESIN, a tripartite protein complex that forms a ring structure to hold sister chromatids together during mitosis and meiosis. Cohesin regulates the separation of sister chromatids during cell division, either mitosis or meiosis. This sister chromatid cohesion is essential for the biorientation of chromosomes on the mitotic or meiotic metaphase spindle, and is thus an essential prerequisite for chromosome segregation. Without the cohesion, sister chromatids would not be segregated symmetrically between the forming daughter cells, resulting in aneuploidy.

Cohesion is established during S-phase of DNA replication, and the cohesins hold the sister chromatid together after DNA replication until anaphase when the removal of cohesin leads to separation of sister chromatids (meiosis II and mitosis) and homologous chromosomes (meiosis I).

Explain how life history traits vary with environmental conditions and with population density
schepotkina [342]
They vary on shape reproduction patterns in species. Traits that affect a organism's schedule of reproduction, selective pressures vary so life histories are very diverse. Life history traits are products of natural selection and an organisms life history comprises the traits that affect schedule of reproduction and survival, and also the traits are evolutionary outcomes reflected in the envelopment, physiology and behavior.
