A. Caves and sinkholes are usually associated with karst topography.
How Karst topography is formed?Karst topography is formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. As water flows through these rocks, it dissolves them, creating underground cavities and channels.
Over time, the ground above these cavities can sink, forming sinkholes. The dissolved rock can also create caves and other unique features such as natural bridges, disappearing streams, and springs.
Karst topography is a type of landscape that is characterized by distinctive landforms and features that are formed by the dissolution of soluble rocks, such as limestone, dolomite, and gypsum.
These rocks are highly susceptible to chemical weathering, which is the breakdown of rocks and minerals through chemical reactions. The process of chemical weathering dissolves the rocks, leaving behind distinctive landforms and features.
Overall, karst topography is a unique and fascinating landscape that is created by the dissolution of soluble rocks. The distinctive features of karst topography, including caves, sinkholes, natural bridges, disappearing streams, and springs, make it a popular area for exploration and study.
However, the hazards associated with sinkholes and other features of karst topography also make it important to be aware of the risks when living or traveling in these areas.

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.

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.

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.
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

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.

Design an experiment that would help you collect the data you have identified in question four independent variable - x , dependent variable - y.
What is independent variable?The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.
The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.
The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.
