This information, along with the discovery that rocks along the mid-Atlantic ridge were younger, was evidence for Seafloor spreading.
What is seafloor spreading?
Seafloor spreading is the hypothesis that the ocean's crust develops along the mid-ocean ridge system's undersea mountain zones and spreads out laterally away from them. The theory of plate tectonics, which revolutionised geologic thought throughout the final quarter of the 20th century, was developed in large part as a result of this concept.
When the seafloor spreads, tectonic plates, which are huge portions of the Earth's lithosphere, split apart from one another. Seafloor spreading and other tectonic activity processes are caused by mantle convection. Mantle convection is the term for the mantle's slow, turbulent circulation.
Hence the correct option is B; seafloor spreading.

If a more concentrated salt solution is on one side of a membrane and a less concentrated salt solution is on the other side, water molecules tend to pass through the membrane.
Cellular water is drawn to salt concentrations which are highest.
A cell will enlarge as it overflows in order to interact with the salt if there was enough salt within than outside. Water will penetrate through into the membrane as well as flow inside if this is the case.By enabling solvent molecules to move through a selectively permeable membrane from a somewhat concentrated solution towards a more concentrated one, osmosis represents a process that typically equalises the solute concentrations on the two sides.The magnitude of both the concentration differential between the opposite sides of the membrane affects how quickly molecules diffuse.

D. addition of biologically available N to an ecosystem / reduces NO. "
Nitrogen fixation results in the addition of biologically available N to an ecosystem while the metabolic process of denitrification reduces NO.
What is the process of denitrification?The denitrification procedure removes bioavailable nitrogen from the environment by converting nitrate to nitrogen gas.
Although nitrogen gas (N₂) is the final byproduct of denitrification, there are also additional intermediate gaseous forms of nitrogen. Nitrous oxide (N₂O), one of these gases, interacts with ozone to form greenhouse gases that cause ozone depletion and air pollution.
Denitrification and other anaerobic processes often occur in an anoxic lake and sea bottom areas, sediments, and soils. There are many different types of prokaryotes that can denitrify, and recent research has shown that some eukaryotes can as well. Bacillus, Paracoccus, and Pseudomonas species are some of the denitrifying microorganisms.

what biogas generator tend to work best in hot countries
The United States generates over 70 million tons of organic waste each year. Biogas is produced after the decomposition of organic matter by bacteria in an oxygen-free environment. This is a process called anaerobic digestion.
Biogas systems use anaerobic digestion to recycle these organics and convert them into biogas which contains both energy and valuable bottom products. Stored biogas can provide a clean, renewable and reliable baseload power alternative to coal and natural gas. Baseload power is generated continuously to cover minimum power demand. Baseload renewables can supplement more intermittent renewables.
Like natural gas, biogas can also be used as a rapidly capable peak power source. Direct use of biogas has the highest efficiency, but the use of this fuel is usually confined to locations close to the anaerobic digester, limiting available markets and applications. Biogas is a methane-rich gas obtained from the anaerobic digestion of organic matter.

Chyme is required to contact the microvilli of the intestinal wall because the brush border enzymes are not secreted into the lumen.
What is chyme?A chyme is a semi-liquid mass of partially digested food that is expelled from a person's stomach through the pyloric valve into the duodenum. Chyme is formed by mechanical and chemical breakdown of the bolus and consists of partially digested food, water, hydrochloric acid, and various digestive enzymes.
Chyme has two main functions: first, it increases the surface area of food so that digestive enzymes can work, and second, it stimulates various digestive glands to produce secretions. The action of the enzyme requires direct contact with the substrate molecule.
When food enters the stomach, stomach muscles mix the food and liquid with digestive juices. The stomach slowly expels its contents, called chyme, into the small intestine.

in ____, one allele is dominant to a recessive allele.
In Simple Dominance, one allele is dominant to a recessive allele.
Simple dominance occurs when a single gene codes for both the dominant allele and the recessive allele of an inherited characteristic. The dominant allele of the gene masks the recessive allele.
what is dominant and recessive allele?
The relation between different genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent. If the alleles are distinct, only one of the gene's alleles—referred to as the dominant gene—will be displayed.
For instance, because the dominant gene for brown eyes only needs one copy of the 'brown eye' allele to result in brown eyes (although, with two copies you will still have brown eyes).
Recessive alleles are a subset of alleles that do not affect a person when they are present alone.
For instance, you need two copies of the "blue eye" allele because it is recessive in order to have blue eyes.
