<span>Stem cells. There are two types of stem cells: adult stem cells - these are unspecialised cells that can develop into many (but not all) types of cells. Embryonic stem cells - these are unspecialised cells that can develop into any type of cell. And that's all! ;)

What does topography show?
muminat

Answer:

I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.

II. The shape of the land.

Explanation:

In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a topographic map is used to graphically describe this features.

A topographic map can be defined as an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of the Earth.

A topographic map is a two-dimensional model that uses contour lines to represent points of equal elevation above sea level such as mountains, hills, plains, valley etc.

The two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.

Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface.

Hence,a topography show two (2) main things and these includes;

I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.

II. The shape of the land.

A marine biologist has dredged up an unknown animal from the seafloor. Describe some of the characteristics that could be used t
jeka57 [31]

Answer:

The first thing to look at would be type of symmetry the organism exhibits. If it is asymmetrical then it would be a sponge and the discovery could stop right there. If not, other characteristics need to be investigated.

Knowing the type of body cavity this organism has would be helpful.

It would also be beneficial to know what type of skeleton (endo or exo) this organism has and what its appendages look like.

Finally, the type of digestive tract and the presence or absence of a head would help to determine what this creature is.

what introduced species on macquarie island were most responsible for severely degrading the local biological communities, inclu
RideAnS [48]

The culprits for the degradation of local biological communities on Macquarie Island are the rabbits, rats,mice and cats that were non-native species were introduced by humans.

The introduction of non-native species to Macquarie Island was responsible for severely degrading the local biological communities, including the vegetation, birds, and invertebrates that were native to the island. The introduction of rabbits, rats, cats and mice led to the loss of native plants, while cats and pigs preyed on native birds and invertebrates. These introduced species caused extensive damage to the local ecosystem, resulting in the loss of native species and the decline of the island's biological diversity.

The new species competed for resources and habitat, and often preyed upon the native species. This had a devastating impact on the local ecosystem, and led to the decline of many native species. The introduction of rabbits was particularly damaging, as they caused widespread destruction of the native vegetation. This had a knock-on effect on the birds and invertebrates that depended on that vegetation for food and shelter. The decline of the native species has had a significant impact on the biodiversity of Macquarie Island, and has resulted in the loss of many unique and valuable species.

These species have wreaked havoc on the island, preying on native birds and other small animals, as well as destroying vegetation. The impact of these introduced species has been so severe that the island has been declared a World Heritage Site. In order to protect the remaining native species on the island, a eradication program was launched in the 1990s to get rid of the introduced animals. While this program has been successful in reducing the populations of these animals, they continue to pose a threat to the island's ecosystem.
