Answer: The curvature of the crystalline lens increase
Explanation:
Since accommodation is the ability of the eye lens to change in shape so as to focus on an object. So, when we look at a far-away object, the ciliary muscles relaxes and moves away from the lens making the suspensory ligaments tight, pulling the lens, and causing its crystalline curvature to become thinner (decrease), so that light rays passing through it are bent less enabling them to focus on the retina.
However, the reverse happens when the human eye focus is switched to a near object, such that: ciliary muscles contracts, suspensory ligaments slackens, and crystalline lens becomes more curved (increase)
Thus, the change in accommodation makes the curvature of the crystalline lens to increase
Answer:
hypothesis
Explanation:
A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge. A prediction is a statement that tells what will happen under certain conditions. Evidence is any type of data that may either agree or disagree with a prediction, so it may either support or disprove a hypothesis.
Is that in evolution? Genetic modifications and advancement in DNA helps organisms survive better in their environment
Answer:
Monohybrid cross:
Monohybrid cross may be defined as the cross done by taking single trait at a time. The ratio of the monohybrid cross by the pure parent breed result in the formation of 3:1 phenotype in the second generation.The genotype ratio is 1:2:1.
Test cross:
Test cross may be defined as the cross between the unknown genotype and the recessive parents. This cross is done to determine whether the genotype is heterozygous or the homozygous dominant trait. The ration of the cross may vary depending on the genotype of the organism.
Answer:
External factors include physical and chemical signals. Growth factors are proteins that stimulate cell division. – Most mammal cells form a single layer in a culture dish and stop dividing once they touch other cells. Two of the most important internal factors are kinases and cyclins.
