14. To determine the correct answer between option A and D, let's break down the statements and analyze them.
Option A: "The cell may become too large to remove enough wastes."
Option D: "Waste products can't leave the cell if it's too small."
Both options A and D mention waste removal as a critical aspect in limiting cell growth. However, option A states that if the cell becomes too large, it may not be able to remove enough wastes, implying that a larger cell would have difficulty eliminating waste products effectively. On the other hand, option D states that if the cell is too small, waste products can't leave it. This suggests that a smaller cell may have limited capacity for waste elimination.
From a logical standpoint, it is reasonable to conclude that as a cell grows larger, the demand for waste removal increases, making option A the correct answer. Therefore, the correct choice is:
a. the cell may become too large to remove enough wastes.
2. Let's evaluate the different options given for the correct order of events during meiosis.
Option A: "The cytoplasm divides, chromosomes line up at the equator, nuclear envelope forms."
Option B: "Chromosomes become visible, chromosomes line up at the equator, chromosomes gather at the poles of the cell."
Option C: "Homologous chromosomes move to the equator, chromatids move to opposite poles of the cell, spindle forms around chromosomes."
Option D: Both B and C.
To determine the correct sequence of events during meiosis, we need to understand the various stages and their order. The correct order is as follows:
1. Chromosomes become visible (condensation).
2. Homologous chromosomes line up at the equator (metaphase I).
3. Homologous chromosomes move to opposite poles of the cell (anaphase I).
4. Spindle forms around chromosomes (prometaphase I).
Considering the given options, option B only matches the correct order for the events during meiosis. Thus, the correct choice is:
b. Chromosomes become visible, chromosomes line up at the equator, chromosomes gather at the poles of the cell.
3. Let's analyze the options provided to determine Gregor Mendel's contribution to the study of genetics.
Option A: "He determined four hypotheses that form the basis of the theory of heredity."
Option B: "He confirmed the current theory that offspring were a blend of the traits of their parents."
Option C: "He was able to determine that patterns of heredity could not be predicted."
Option D: "He invented the Punnett square to predict the pattern of heredity."
Gregor Mendel's contribution to the study of genetics involved his experiments with pea plants, which led to the establishment of fundamental laws of inheritance. His work discovered specific patterns of inheritance that contradicted the notion of traits blending together. Instead, Mendel proposed that traits were inherited in discrete units, which are now known as genes. His findings formed the basis of modern genetics and challenged the prevailing theory of blended inheritance.
Therefore, the correct choice is:
a. He determined four hypotheses that form the basis of the theory of heredity.
