B. The cells in between failed to grow
Making them not the same but not very different
Answer:
Sensory adaptation.
Explanation:
When the sensory receptors are exposed to a constant stimulus for a prolonged period, the receptors decrease their ability to respond and this leads to a decreased sensitivity of the stimulus. This phenomenon is referred to as sensory adaptation.
Sensory adaptation occurs in all of our five major senses. From taste to smell, touch, sight and hearing. This mechanism is used by the body to ignore trivial and unimportant stimuli and direct our attention to other stimuli around us.
Other examples of sensory adaptation are;
A) When we adapt to constant noise coming from a particular source such as a disco hall.
B) When we no longer notice the smell of our deodorants.
C)When the eyes adjust and adapt to a dark room.
The equation for the process of photosynthesis is:

Fewer plants can bring a huge change in the environment resulting in less oxygen and more carbon dioxide.

weathering away or change the appearance or texture of (something) by long exposure to the air.
erosion the process of eroding or being eroded by wind, water, or other natural agents.
deposition the action of deposing someone, especially a monarch.
Answer:
Which type of selection tends to increase genetic variation? A. Disruptive selection B. Directional selection C. Stabilizing selection
The Answer is option A (Disruptive selection)
Explanation:
Selection can either shift the mean value of a trait, reduce the trait's variation, or increase its variation.
Genetic variation which allows natural selection to increase or decrease frequency of alleles already in the population is a source of phenotypic variation as it refers to differences in all the hereditary information of members of the same species.
Disruptive Selection is important in maintaining variation and initiating speciation as it Increases Variation by favoring alleles corresponding to more extreme phenotypes. But for it to occur, the mean phenotype has to experience the lowest fitness. Disruptive selection affects the frequency distributions of alleles and genotypes within a population.
Disruptive selection is based on the variance of a trait in a population as it increases genetic variance by equalizing the frequencies of existing alleles at polymorphic loci (a genetic loci with two or more alleles). Disruptive selection maintains and may even increase variation in natural populations by favoring extreme phenotypes, individuals with extreme values for a trait have greater reproductive success than individuals with intermediate values.
