The complete question is :
The success of plants extending their range northward following glacial retreat is best determined by _____.
A) whether there is simultaneous migration of herbivores
B) their tolerance to shade
C) their seed dispersal rate
D) their size
Answer: The seed dispersal rate
Explanation:
The seed dispersal can be defined as the movement of the seeds away from the parent plant. The ability of the plant to extend is completely dependent on the ability of the plant to disperse its seeds.
Plants have very limited ability, they need vectors to carry its seed from one place to another.
The biotic and abiotic vector both are involved in carrying the seeds which helps in expansion of the trees.
hence, the correct answer is option C
The relationship between ionic bonds and cleavage is "as the ionic bond strength increases, cleavage will be more difficult".
There are ionic bonds between the minerals that held them together. Ionic bonds are the consequence of electrostatic fascination and electron exchange amongst positive and negative particles (cations and anions). Ionic bonding infers the development of requested crystalline solids and the cleavage of those solids will rely upon the quality of this bonding.
Answer:
They are genetically identical to the parents and only differ if a genetic mutation occurs.
Sexual reproduction involves two parents and produces offspring that are genetically unique.
The greater the genetic variation, the better change that an individual in the population have a favorable gene that can help survival. Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population.
Explanation:
Answer:
Alcohol fermentation
Explanation:
When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration
One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.
Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture
This process is taken advantage of to brew beer and wine.
Calcite is the most common rock
