invertebrates developed


C.

single-celled life


D.

Answer 1

Answer:

E B C

Explanation:

thats the 3

Answer 2

The characteristics of the Cambrian period are all life lived in the sea, Vertebrates developed, and Single-celled life. Options (A) (C) and (E) are correct.

What are invertebrates?

An invertebrate is a cold-blooded animal having no backbone. Invertebrates can live on the land including insects, spiders, and worms, or in water including crustaceans (crabs and lobsters), mollusks (squids and clams), and coral.

The Cambrian Period is an important point in the history of life on Earth. it is the time when the first vertebrate fishes appeared in the fossil record. The Burgess Shale contains the best record of Cambrian animal fossils, including soft-bodied forms.

Therefore, Options (A) (C), and (E) are correct. All life lived in the sea, Vertebrates developed, and Single-celled life.

The climate region labeled with the number 1 on the map above is the __________ region

Answers

The climate region labeled with the number 1 on the map above is the ARID region

Explanation:

A region is arid when it is characterized by a severe lack of available water, to the extent of hindering or preventing the growth and development of plant and animal life.Arid regions by definition receive little precipitation—less than 10 inches (25 centimeters) of rain per year. Semi-arid regions receive 10 to 20 inches (25 to 50 centimeters) of rain per year. Most of the world's arid climates lie just north and south of the tropical rain forests of the equator. Mountain plateaus are another location where you might find an arid climate. The southwestern corner of the United States, for example, is quite dry and hot.Cold currents carry dry air, so these lands are blasted with dry air most of the year, which causes the low precipitation.Environments subject to arid climates tend to lack vegetation and are called xeric or desertic.

Explanation:

Part C - Karst Topography Recall from the introduction that karst topography exists because some minerals dissolve when they come into contact with rainwater. Minerals that contain calcium carbonate are especially susceptible to dissolving. Sinkholes and springs are common karst landforms that have the following characteristics: • Sinkholes can develop slowly where rainwater infiltrates te dissolving soil and rock, slowly lowering the ground surface of an area. In these instances, sinkholes are shallow with gently sloping sides • Sinkholes can also form rapidly and catastrophically when the cave ceiling collapses, resulting in deep sinkholes with steep walls • Rainwater in karst landscapes flows on the surface differently than other types of terrain. Streams are fewer and less developed in karst areas because water readily infiltrates the ground • Limestone dissolution is often not spatially uniform. In some circumstances, nonuniform dissolution can lead to the formation of lower karsts, which are large structures of rock that have dissolved at a much lower rate than the surrounding rock that has eroded away Which of the following is true about karst landscapes? Select the two that apply. View Available Hints) Sinkholes form from the same process as cave formations the dissolution of minerals Consider two regions (Region A and Region B) with the same type of environment (eg, climate) except Region A has karst topography Region A must also have more streams. A karst landscape is expected in the southwestern United States where conditions are dry Karst topography erodes at different rates, meaning that tall karst towers might form. Sinkholes that form abruptly tend to be shallow and have gone, not stop walls

Answers

Final answer:

Karst topography forms as a result of the dissolution and erosion of soluble rocks, such as limestone. This often results in sinkholes and caves. The landscape varies as the rate of erosion and dissolution can differ across the area.

Explanation:

The options about karst landscapes that are true are: 'Sinkholes form from the same process as cave formations: the dissolution of minerals' and 'Karst topography erodes at different rates, meaning that tall karst towers might form.'

Karst topography emerges due to the erosion and dissolution of soluble rocks such as limestone. The process of dissolution often leads to the formation of sinkholes and caves, leading to a unique landscape. Different rates of erosion could result in the formation of tall karst towers.

It's also worth noting that the presence of a karst landscape does not necessarily mean that there are more streams in that area. Water in karst areas often infiltrates the ground, leading to fewer and less developed surface streams.

Which is not a result of the low water level of the Danube River?

a
Fish are dying in record numbers
b
Unexploded WWII bombs have been exposed
c
Ships and barges have become stranded
d
Illegal immigrants are wading across the river

Answers

The correct answer to the question of which is not a result of the low water level of the Danube River is option d, as it pertains to illegal immigrants wading across the river, which is unrelated to environmental consequences like those listed in options a, b, and c.

Which is not a result of the low water level of the Danube River? The options a, b, and c are indeed consequences of low water levels, as they can lead to the exposure of previously submerged hazards such as unexploded WWII bombs, stranding of ships and barges, and the death of fish due to changed habitats and water conditions. Option d, illegal immigrants wading across the river, is not directly a result of low water levels because the primary concern with illegal immigration would be border enforcement and security rather than environmental factors like river water levels.

Low water levels in rivers can cause significant environmental degradation, which is often reflected in the form of reduced fish populations and uncovered hazards. Such conditions can severely impact both natural ecosystems and human activities such as navigation and fisheries. However, the wading of illegal immigrants across the river is less about environmental issues and more about border security and human migration patterns.

characteristics of it's waves?

Answers

Seafloor of the Galveston is full of sand and sediment which is suspended in and around the bay.

Explanation:

The water in and around the Galveston bay. The reason for the water to be brown in that area is because of the sediments and other material which are suspended to be brown in the water.

The water in the Galveston is shallow as a reason of which the sediments and the sand turn over in that area is high, making it look brown in color instead of blue. Thus water seems to be dirty and muddy at many point of time.
