The given blank can be filled with Cones.
The visual acuity can be defined as the clarity of the vision, it is related to the sharpness and the clearness of the image formed. The vision acuity is determined by the optical and the neural factors, it is dependent on the retinal focus and the sensitivity of the nerve cells and the brain.
The cones are the pointed, thick and short sensory receptors, present in the eye. They are responsible for the color vision and the sharpness or the acuity of the image. They work better in brighter light.
Answer:
Option B, Observation 2
Explanation:
The four main observation of Darwin’s areas follows –
Observation 1 – Variation occurs in the species with time leading to evolution. Offspring of two parents vary distinctly in traits such as height, color, weight etc. These variations are also affected by the surrounding environment
Observation 2-
Based on observation 1, Darwin concluded that offspring inherit traits from their parents. These traits improve the odds of survival and only genetic traits will be passed. Traits developed in an individual due to environment will not be passed on.
Observation 3 –
Offspring compete among themselves to survive.
Observation 4
The fittest among the competing species for survival will survive and pass on its traits to the next generation.
Since here the Pigeon breeders want to exemplify the looks (a genetic trait) of parents to their offspring, observation 2 applies here
Hence, observation b is correct

Answer:
opponent-process theory
Explanation:
Based on the information provided within the question it can be said that this perceptual phenomenon is best explained by the opponent-process theory. This theory explains that when one color pair is activated it triggers activity from another pair, meaning that the three opposing color pairs ( blue/yellow, red/green, and black/white) are all linked together. Which is why Sharon saw red when looking at a white surface.
Cell division occurs in all living organisms. This is known as mitosis.
The advantages of a larger organisms to subdivide themselves into smaller cells is that as all organisms grow, some of their cells die or get damaged with time and need replacements. So,it divides into smaller cells because when a cell becomes large, it demands more of cell places of its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. So to grow properly the cells need to be divided.
