True or false? A mating between a tetraploid individual and a diploid individual produces biologically fit offspring.

Katyanochek1 [597]

A cross between a diploid individual and a tetraploid individual produces triploid offspring. There are many species of plants that are triploid, but those come from crosses between two triploid individuals. In those cases, the chromosomes from one parent match up with the chromosomes from the other parent just fine. The same is not true with a cross of a tetraploid and a diploid. In that case, one third of the chromosomes are unmatch, causing many offspring to die, to be sterile, or to be generally unfit. Long story short, the answer you seek is False.

What determines the type of igneous rock that forms from magma? a. The heat and pressure the magma is exposed to b. Whether the

Answer:

c. Magma composition and cooling rate.

Explanation:

A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.

Basically, the three (3) main types of rocks are; metamorphic rock, sedimentary rock and igneous rock.

All igneous rocks are produced from magma (lava) and formed at the Earth’s surface, thereby, causing them to have a coarse texture and dark colors.

Generally, the cooling and solidification of magma (lava) leads to the formation of an igneous rock, either when the melted rock is still inside the continental crust of the Earth or at volcanoes on the Earth's surface.

Hence, magma composition and cooling rate determines the type of igneous rock that forms from magma. Some examples of an igneous rock are granite, obsidian, tuff, basalt, rhyolite, andesite, pegmatite, dacite, scoria, pumice, etc.

Access Control Points

They are restrictions points that enforce regulations and guidelines on decontamination when exiting the sites and ensuring adherence safety standards when entering the site. The regulation are usually, as standard practice, conspicuously posted at the Access Control Points.
Access Control Points are usually set up at the periphery of the Exclusion Zones, and ideally, there should be a separate entrance and exit Control Access Point.
