Answer:
All of these are correct
Explanation:
According to the question, marble is a rock formed from limestone, which in turn is also formed from Calcite. This shows that marble is a kind of metamorphic rock because a metamorphic rock is any rock that is formed by the alteration of other rocks caused by heat, pressure or chemicals etc. These changes that occurs in the previously existing rocks are called METAMORPHOSIS.
Hence, since marble is formed from limestone, it concludes that marble is a metamorphosed rock formed from a previously existing limestone rock. Also, since Calcite, a precursor of limestone that marble is formed from can be degraded by acids, both limestone and marble which are formed from it will also be dissolvable by acids.
which of the following correctly orders the zone of depths in a lake from shallowest to deepest?
A. profundal, littoral, limnetic
B. Littoral, profundal, limnetic
C. Limnetic, littoral, profundal
D. Littoral, limnetic, profundal
Answer:
D. Littoral, limnetic, profundal
Explanation:
The level of water bodies like ponds and lakes are divided into different zones from top to bottom and side to side. The Littoral zone starts from the dry land that moves in a downward direction towards the open water. There are lots of nutrients and minerals in this zone. Insects, small fish, and zooplankton live in this zone. The limnetic zone starts after the littoral zone ends. It is the part of the pond which receives the sunlight. Algae and other plants live in this zone because the level of oxygen is high in this area. The profundal zone is located where the sunlight does not reach. The population of fish is very low in this zone.
Answer:
Littoral, limnetic, profundal

The image shows a paramecium and a bacterium. One of these organisms is very good at rapidly adapting to environmental changes because it has the ability to take in stray genetic information from the environment. Which structure allows the organism to do this?
Answer:
The bacteria forms new kind of cells to adapt to a new environment. This adaptation is under tight genetic control, involving the expression of multiple genes.
the bacteria need to adjust their enzyme levels in order to quickly benefit from the nutrient mix that is currently available in the surrounding.
If the living environment undergoes a sudden change, the bacterium's own production of proteins has to fulfill these changes in an effective way.
The following picture shows the three primary types of plate boundaries. Which boundary is being shown in label A? an arrow pointing from A to a formation of trenches and Island Arcs, an arrow pointing from B and C to an Oceanic Spreading Ridge, and an arrow pointing from D to a trench. © 2016 US Department of the Interior; US Geological Survey Divergent boundary zones Convergent boundary zones Plate boundary zones Transform boundary zones
Answer:
The label A corresponds to Convergent boundary zones
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped volcanic islands, the island arches. Subduction zones coincide with deep-sea trenches or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.

Convergent boundaries

What is a similarity between a tulip and a crocodile? A function of both of their outer coverings is to reduce water loss. In both the tulip and crocodile the male reproductive organ is the testes. The tulip and crocodile both have internal skeletons that support them. The outer coverings of the tulip and crocodile both protect the organism.
Answer:
A function of both of their outer coverings is to reduce water loss
Explanation:
Crocodile and Tulips are both distinct species of organisms. Crocodile belongs to Kingdom Animalia while Tulips belong to Kingdom Plantae. However, despite their elaborate differences, they do have one feature in common, which is the function their outer covering performs.
Tulips are temperate plants I.e. like cold regions, hence, their outer covering functions to prevent excessive loss of water. On the other hand, the scaly skin of the crocodiles help them against water loss. This is common between the two different species.

Please help me, and only provide with the given answers so I am not confused. The curve on the left shows the height of a population of penguins. The curve on the right shows the population five years later. What has happened to this population? (Available answers are in photo) Will mark best answer BRAINLIEST
Explanation:
DIRECTIONAL SELECTION!!!!!!!!!!!!!!!!!!
The population of penguins has gone through the directional selection.
What is directional selection?It is a mode of negative natural selection in which an extreme phenotype is favored over other phenotypes.
This causes the allele frequency to shift over time in the direction of that extreme advantageous phenotype.
How these two graphs shows directional selection?On each graph, the X-axis variable is the type of phenotypic trait (here height) and on the y- axis variable is the number of penguins.
Left graph shows the population before directional selection and right graph shows the population after directional selection.
Here height of the penguins reduces and favored over time due to directional selection.

Plants absorb sunlight through Photosynthesis. Which characteristic of life is this an
example of?
A. Obtains and uses energy
B. Responds to stimuli
C. Grows and develops
D. Homeostasis
Answer:
A. Obtains and uses energy
The characteristic of life shown here is plants obtain and use energy.
What is photosynthesis?By using the energy from sunlight, plants, some bacteria, and some protozoa make sugar, which cellular respiration then transforms into ATP, the "fuel" that all living things use. The green pigment chlorophyll is responsible for the transformation of inefficient solar energy into useful chemical energy. The photosynthetic process makes use of water and emits the oxygen that is vitally necessary for our continued existence.The overall reaction of photosynthesis is:6H₂O + 6CO₂ + light energy → C₆H₁₂O₆+ 6O₂

Which one of the following statements about the troposphere is
true?
Select one:
a. The troposphere is the atmospheric layer farthest from
the earth's surface.
b. The tropospheric gases move because of convection
currents.
c. The temperature in the troposphere ranges from 100° C
to -150° C.
d. The outer boundary of the troposphere is called the
stratopause.
e. Weather does not occur in the troposphere.
Answer:
B. The tropospheric gases move becuase of convection currents.
Explanation:
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. In the Northern and Southern hemispheres, air rises along the equator and subpolar ( latitude about 50 to about 70 north and south ) climatic regions and sinks in the polar and subtropical regions. Air is deflected by the Earth's rotation as it moves between the poles and equator, creating belts of surface winds moving from east to west ( easterly winds ) in tropical and polar regions, the winds moving from west to east ( westerly winds ) in the middle latitudes. This global circulation is disrupted by the circular wind patterns of migrating high and low air pressure areas, plus locally abrupt changes in wind speed and direction known as turbulence.

Detailed descriptions of what happens to the carbon atom:
during photosynthesis (the light-dependent reactions and the light-independent reactions)
transitioning between photosynthesis and respiration
during cellular respiration or fermentation
An explanation of how the carbon atom is transferred between molecules. Please include descriptions of the molecules involved in each of the processes above and be sure to mention the movement of electrons and energy as the carbon atom moves from one reaction to another.
During cellular respiration:
The cell is oxidized.
Transitioning between photosynthesis and respiration:
It is taken from CO2 converted to glucose then either converted back to CO2 or it is used for other processes and may expelled another way.
How is the carbon atom transferred between molecules:
The electrons move through a series of electron carrier proteins, called the electron transport chains, within the thylakoid membrane.For every 12 of the resulting three-carbon molecules made, two are removed to build organic compounds and 10 continue on in the cycle. The two three-carbon molecules that are removed bond together, forming a six-carbon sugar such as glucose.
What happens to the carbon atom during:
Photosynthesis: carbon is taken in from the air, in the form of carbon dioxide and through the energy provided from sunlight it is converted to a carbon chain known as a sugar.
Explanation:
