Answer:
All of the above
Explanation:
CAM leaves the stomata closed during the day. They are most common in hot, arid environments. During the night, when their stomata are open, these plants take up CO2 and incorporate it into a variety of organic acids.
B. It provides information about why certain measurements are made in an experiment
From experience, to be able to have background research helps in the design of an experiment because it would tell you what is being measured in a experiment. Without the background information, my whole class got lost on what to do until my teacher told us what we had to measure and how we could measure the experiment.
Given Question:
Can prokaryotes exchange genes with each other?
Answer: <u>True</u>
Explanation:
By the process of conjugation, their DNA is <u>transferred</u> from one prokaryote to another by means of a pilus, which brings the organisms into contact with one another. The DNA transferred can be in the form of a plasmid or as a hybrid, containing both plasmid and chromosomal DNA.
Answer:
1. 80 chromosomes are found in each of the daughter cells. 2. Two daughter cells are produced. 3. The daughter cells are identical to each other.
Explanation:
Mitosis is simply a process of cell division whereby two daughter cells that are genetically identical are produced from a single parent cell. A cell having 80 chromosomes would undergo Mitosis through these various stages:
Interphase: This can be referred to as the rest phase between cell division when mature enough for reproduction. This is a preparatory stage where DNA is duplicated and ready for the division of chromosomes
Prophase: This stage marks the beginning mitosis of the cell with 80 chromosomes. The chromatin threads start a coiling process in which the chromosomes become condensed to enable easy distribution to daughter cells without tangling.
Prometaphase: This phase commences toward the end of the prophase, where the nuclear envelop breaks down. The chromosomes move toward to the center of the cell.
Metaphase: At this stage, the duplicated chromosomes line up on the mid plane or equator of the cell. During this stage, each chromatid is condensed completely and appears thick and distinct.
Anaphase: At this stage, the chromosomes move toward the poles as each replicated copies of the DNA of the cell ends up on either side of the cell. What we would have here at this stage is an entirely two new sister chromatid having 80 chromosomes. Cytokinesis begins towards the end of this stage as the parent cell cytoplasm divides which also continues at telophase.
Telophase: This is the final phase of Mitosis where two separate nuclei are formed and Cytokinesis takes place to complete the division of the cell to form two daughter cells having the same number of chromosomes. These cells are genetically identical to the original parent cell.
