Answer:
Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER.
Explanation:
In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome.
<span>Damming a river has a variety of effects on the freshwater ecosystem, more than just altering the flow from A to B. Dams create calm bodies of water, changing overall temperature regimes and sediment transport, leading to conditions which tend to favour generalist species. Loss of specialist species, particularly endemics, changes the community structure and leads to biotic homogenization. A dam will withhold sediment in the reservoir, not just decreasing the amount of substrate available to local freshwater species, but even impacting diadromous, estuarine and marine species much further downstream. The competition between resident species for food and breeding sites will increase as damming isolates populations, and perhaps more importantly, damming completely restricts migratory fish species. Isolation may lead to decreases in genetic diversity and therefore puts species at greater risk from disease. All of these effects may be exacerbated by changes in the surrounding land use. Overall, damming river flow will lead to both a loss of native species, but also an increase in exotic species which are more likely to become established in degraded habitats. For this reason, dams are one of the greatest global threats to freshwater biodiversity.</span>

Sex is important because its how we reproduce we create new life so that they can create new life and so on with out sex theres no life if that makes sense
The Principle of <u>segregation</u> states that the 2 alleles present at each gene locus separate from one another during gamete formation and remain distinct.
What is principle of segregation?
According to the principle of segregation theory, every human has two alleles for each specific feature and functions, and these alleles separate throughout the development of gametes. In other words, in everycase, each gamete contains a single allele.
Therefore, The Principle of <u>segregation</u> states that the 2 alleles present at each gene locus separate from one another during gamete formation and remain distinct.
