Sinkholes and caves are an example of:
A. Climate Change
B. Mechanical Weathering
C. Sediment Deposition
D. Karst Topography
Answer:
I think it's D. Karst Topography
Explanation:
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions.

What is the role of DNA polymerase in DNA Replication?
reads one strand of DNA and creates another strand
unwind and unzip the DNA
repair errors
bind sugars to phosphates in the backbone
Answer:
One of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.
What is the measured output force of a pulley system if the Mechanical Advantage is 0.48 and measured input force is 10N?
Answer:
Output force is 4.8 N
Explanation:
A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.
The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.
The mechanical advantage of a pulley is the ratio of the output force to the input force.
Mechanical advantage = output force / input force
Substituting:
0.48 = output force / 10
Output force = 4.8 N

Los organismos sencillos como las bacterias, los protozoos, las algas y los hongos no tienen sistema especializado para la excreción, la excreción se efectúa por difusión y transporte activo a través de
Answer:
Por difusión.
Explicación:
Los organismos simples como las bacterias, los protozoos, las algas y los hongos no tienen un sistema de excreción especializado. Hicieron la excreción a través del proceso de difusión en el que los materiales se mueven de la región de alta concentración a la región de menor concentración. Debido a esta difusión, hay una gran cantidad de material de agua presente, por lo que el material de desecho se mueve desde el interior del cuerpo al entorno exterior a través de la membrana presente alrededor de su cuerpo y este proceso de difusión también se utiliza para la absorción de nutrientes.
Which of the following is a mixture?
Answer:
⭕ AirHOPE IT helps!
Answer:

plz help with my hmwk
This process is based on a chemical reaction that occurs when the warm exhaust gases from the coal-fired boiler come into contact with limestone.
When the warm gas comes into contact with the limestone slurry a chemical reaction occurs between the Sulphur Dioxide (SO2) in the gas and the limestone.
This reaction removes the SO2 from the flue gases and converts the limestone into Calcium Sulphite.

During the day, plants produce

same time, plants use cellular respiration to produce some of the
needed by the
sugars. During the night, plants produce
because
place.
Answer:
Throughout the day plants manufacture oxygen via light-dependent photosynthesis by dividing water molecules.
In thylakoid membranes of chloroplasts, light-dependent processes occur and start with light energy absorption. This energy (including water and photosystems) is employed in the formation of ATP and NADPH, the reduced electron carrier necessary for the next photosynthesis phase. It releases oxygen.
Explanation:
At the same time, cellular respiration is used by plants to produce some of the carbon dioxide required for light-related sugar processes.
Cellular breathing is a chemical reaction of plants where glucose and oxygen are used to make carbon dioxide, water, and energy.
The plants create carbon dioxide at night, but not oxygen, due to cellular breathing.
At night there is no daylight, thus only cellular breathing happens.
During the day plants undergo a photosynthesis process, in which electrons are excited by light and electrons to begin flowing via Z-scheme. This electron flow causes PS II resonance and splitting of the water leading to the creation of O2 as a by-product. Cells in plants conduct simultaneous cell breathing to make ATP and produce CO2 during the interaction with the breathing cycle of cancer.
During the afternoon, no sunshine causes plants to photosynthesize and cells only breathe in order to make ATP carbon dioxide the by-product.

Ferns have vascular tissue, an adaptation to life on land, but they have an ancestral reproductive trait that tends to limit them to moist habitats. What is it?
Answer:
The correct answer is - flagellated sperm.
Explanation:
In ancestral trait that is flagellated sperm in ferns that were limited to moist habitat has sperms that must swim to the eggs. This is why ferns often require splashing water for the movement of sperm to points near female gametangia during reproduction.
Fern now adapted the vascular system to get life on the life and they are not limited to the water bodies, however, flagellated sperm is the ancestral reproductive trait.
