Answer:
Question: Two requirements for gas exchange which are accomplished by the gills in a fish include:
1. Water flowing in opposite directions across the gill lamellae for gas exchange, in other words, respiration is experienced by the fish.
2. The fish allows water through its mouth, then forces the water to drain through the gills supporting gill lamellae, and enhancing gas exchange.
Question: How does their structure help to satisfy these requirements?
1. The rows of gill filaments with numerous folds through diffusion makes sure oxygen from the water moves from a place of more concentration to the blood of the fish which has less concentration causing the removal of carbon dioxide.
2. The large surface area of the gill means it has to maximize the low percentage of dissolved oxygen in the water compared to the higher percentage of oxygen in the air makes it possible for water to pass through the mouth and empty through the gills after the mouth is closed.
Answer:
d. The cell begins to elongate and the two poles have an equivalent collection of chromosomes.
Explanation:
The cell cycle is a fundamental cellular process by which a parent cell divides into two or more daughter cells. In somatic cells, this cycle can be divided into two major phases: interphase, where the cell prepares for its division, and mitosis or 'M phase'. The M phase can in turn be divided into four stages: 1-prophase (also divided into early prophase and prometaphase), 2-metaphase, 3-anaphase, and 4-telophase. During prophase, chromatin condenses, thereby forming visible chromosomes. Subsequently, during metaphase, the sister chromatids (i.e., the two identical halves of a single replicated chromosome) align along the middle of the cell at the metaphase plate by attaching their centromeres to the spindle fibers. Next, during anaphase, sister chromatids are separated and move to opposite poles of the cell, pulled by the mitotic spindle fibers. At the end of anaphase, the microtubules of the mitotic spindle pull the two sister chromatids toward opposite poles, thereby the cell gets begins to lengthen. Finally, during the telophase, daughter chromosomes arrive at opposite poles and uncoil, while daughter nuclei begin to form at the two poles and nuclear envelopes are formed.
