Answer:
If mitosis skipped any of the stages, it would result in a mutated cell. If the cell skipped Metaphase, it could make daughter cells that are different than the parent cells. If the cell skipped Telophase, the cell would not divide, and the parent cell would attempt interphase with another nucleus.
Explanation:
The cell cycle has two main phases, interphase and mitosis. Mitosis is the process during which one cell divides into two. Interphase is the time during which preparations for mitosis are made.
Troposphere
The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region.
Stratosphere
The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer.
Mesosphere
The mesosphere starts just above the stratosphere and extends to 85 kilometers (53 miles) high. Meteors burn up in this layer
Thermosphere
The thermosphere starts just above the mesosphere and extends to 600 kilometers (372 miles) high. Aurora and satellites occur in this layer.
Ionosphere
The ionosphere is an abundant layer of electrons and ionized atoms and molecules that stretches from about 48 kilometers (30 miles) above the surface to the edge of space at about 965 km (600 mi), overlapping into the mesosphere and thermosphere. This dynamic region grows and shrinks based on solar conditions and divides further into the sub-regions: D, E and F; based on what wavelength of solar radiation is absorbed. The ionosphere is a critical link in the chain of Sun-Earth interactions. This region is what makes radio communications possible.
Exosphere
This is the upper limit of our atmosphere. It extends from the top of the thermosphere up to 10,000 km (6,200 mi).
Answer:
A cladogram is a diagram used to represent a hypothetical relationship between groups of animals, called a phylogeny. A cladogram is used by a scientist studying phylogenetic systematics to visualize the groups of organisms being compared, how they are related, and their most common ancestors.
Answer:
<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring will all be heterozygous and increase chances of future variation.</em>
Explanation:
The cross for the offsrings that will be produced by F1 generation is shown below:
a a
A Aa Aa
A Aa Aa
As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.
A cross between the F1 generation will give the following results:
A a
A AA Aa
a Aa aa
This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.
Answer:
The movement and interaction of tectonic plates helps to explain many of Earth's features. Interpret data showing topography, the age of the sea floor, the location of volcanoes, and the location of earthquakes to predict the location and type of plate boundaries in a region.
