White perch is a fish that is native to Atlantic coastal regions and is invasive to the Great Lakes. It feeds on native species
VARVARA [1.3K]

ANSWER:  Trapped in a ship's ballast or water tank.

REASONING:  There are many examples of species being transported in the ballast or water tank of ships.  Ships need to be stable so they don't turn over.  Stability is provided by weight in the bottom part of the ship called the ballast.  This weight often comes from water that is stored in water tanks or the ballast area of the ship.  Water is taken in to the ballast at the beginning of its voyage.  When it arrives at it's destination, the ballast water is often drained.  Anything living in that water will also be drained in to the new location.  This is how species like the white perch can be introduced into new areas.

crustal formation,which may cause the widening of an ocean is most likely occurring at the boundary between...?
balandron [24]

Divergent boundary.

This is the boundary between two tectonic plates move away from each other in opposite directions.

Explanation:

One major example of a divergent boundary is the mid-Atlantic ridge that cuts, longitudinally, across the middle of the Atlantic ocean.

When two tectonic plates move away from each other in opposite directions, the void they leave in between is filled by rising magma from the mantle and cooling to create new crust. A mountainous ridge along a boundary is evidence of a divergent boundary. The Atlantic ocean will therefore continue to widen as the North American and Eurasian Plates move away from each other. As new crust is formed at divergent boundary, old crust is being consumed at convergent boundary on another end of earth. This way tectonic plates of earth renew themselves.

Human gametes should contain chromosomes each. This number would be considered the
Sophie [7]

Answer:

Human gametes should contain <u>23 </u>chromosomes each. This number would be considered the <u>haploid </u>number for humans. The symbol for this is <u>n</u>.

Explanation:

Gametes are an organism's reproductive cells. Female gametes are called egg cells, and male gametes are called sperm.

In most organisms, somatic cells (all cells except for gametes) are diploid, whereas the gametes tend to be haploid. Haploid cells have a single set of chromosomes, while diploid cells have two sets of chromosomes.

When it comes to human cells, somatic cells have 46 chromosomes. This means that each gamete has 23 chromosomes. This is called the haploid number and is marked by a lowercase <em>n</em>. This number refers to the total number of chromosomes found in a gamete (for human cells n=23).
