The formation of sea ice removes freshwater and dissolved solids from seawater, leading to a decrease in density. The correct option is C.
What is salinity?The concentration levels of salts in water or soils are referred to as "salinity."
Salinity is classified into three types based on its cause: primary salinity (also known as innate salinity), secondary salinity (also known as dryland salinity), and supplementary salinity (also called irrigation salinity).
When the water table rises, natural salts rise to the surface; in sufficient quantities, these salts become toxic to most plants.
As a result, the surrounding seawater becomes saltier because salt is left behind when sea ice forms.
As seawater becomes saltier, its density rises and it begins to sink. Surface water is drawn in to replace sinking water, which eventually cools and salts enough to sink.
Thus, the correct option is C.

During cellular respiration, cells convert the energy stored in glucose to make the energy molecule ATP, as shown in the equation. Less than 40% of the energy found in glucose is actually converted into ATP. What happens to the other 60% of this energy
Answer:
the other 60% of energy is stored away for further use in the cell
Explanation:
i hope im right
In the cell from glucose, 40% of energy is utilised to make ATP and the rest 60% is used in the process of making ATP. So 100% of glucose cannot be converted into ATP.
How does ATP form from glucose?Glucose is a major source of energy. It has carbon, oxygen, and hydrogen . Due to the presence of oxygen, it can easily break down to produce energy during times of need.
Glucose is broken down into pyruvate by the process of glycolysis. In this process, the net gain is 2 ATP. Pyruvate converts into acetyl CoA. ATP is required in this process. Acetyl CoA enters the Krebs cycle.
To enter the mitochondria, ATP is required. Acetyl CoA enters the krebs cycle and electron transport chain. The FADH₂ , NADH are broken. Proton gradient is formed due to the electron movement. Then ATP is formed due to the proton gradient across the inner mitochondrial membrane . To make ATP a lots of ATP have used in the process. So net gain of ATP of a glucose is 40% as rest 60% has used in the process .
Hence, 40% of energy of glucose make ATP, and the rest 60% is used in the process of making ATP.

Answer:
A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.
Answer:
If you are talking about reflexes in the body
Explanation: Some functions are involuntarily performed, such as breathing, digestion, heart beating, eye reflexes, etc., but some involuntary actions have voluntary control to a certain extent – examples are breathing, salivation, deglutition (swallowing), defecation, micturition (urination) and others.

how is the classification of living things related to the structure of their cells?
Answer:
The most basic classification of living things is kingdoms. ... Living things are placed into certain kingdoms based on how they obtain their food, the types of cells that make up their body, and the number of cells they contain. Phylum. The phylum is the next level following kingdom in the classification of living things.
Explanation:
hope these help
The classification of living things significantly depends on the structure of their cells and based on this, they are divided into two types. They are as follows:
Prokaryotes. Eukaryotes. What do you mean by Cell structure?The structure of a cell may be defined as the components through which it has developed. It includes the cell membrane, the nucleus, and the cytoplasm. The cell membrane is a semi-permeable membrane that separates the inner atmosphere of the cell from the outer environment.
The nucleus is a structure inside the cell that contains the nucleolus and most of the cell's DNA. It is also where most RNA is made. When it comes to prokaryotes, they lack a well-defined nucleus and other membrane-bound cell organelles.
Eukaryotic cells generally have a well-defined nucleus and other membrane-bound cell organelles. Apart from this, these types of cells are generally highly compartmentalized as compared to prokaryotic cells.
Therefore, the classification of living things significantly depends on the structure of their cells that has been described above.

Based on the thin layer of sediment on his flooded farm,
James Hutton concluded that strata:
A Are made of large rocks
B
Settle in vertical layers
C
Are formed by catastrophes like floods and earthquakes
D
Take many thousands of years to form
Answer:
D. Take many thousands of years to form
Explanation:
James Hutton discovered thin layers of sediments on his flooded farm and he concluded that strata was part of the earth surface in the past and thus takes many thousands of years to form.
This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.
The passive movement of particles from a region of higher concentration to a
region of lower concentration is known as...
A. Diffusion
B. Active Transport
C. Osmosis
D. Selective Permeability
Answer:
Answer is A. Diffusion
Explanation:
Because diffusion is a passive process in which a substance moves from a higher concentration to a lower concentration until the concentration becomes equal
The passive movement of particles from a region of higher concentration to a region of lower concentration is known as diffusion. Thus, the correct option is A.
What is Diffusion?Diffusion may be defined as the passive movement of particles from a region of higher concentration to a region of lower concentration.
Active transport requires energy for the movement of particles. Selective permeability may be defined as the ability to differentiate the movements of different types of particles in and out of the membrane.
