Answer:
Carbon dioxide production can be measured by breathing through a straw into a solution of bromothymol blue (BTB).
Explanation:
BTB is an acid indicator; when it reacts with acid it turns from blue to yellow. The more carbon dioxide you breathe into the BTB solution, the faster it will change color to yellow.

What are the ratios of the phenotypes of the children in
Snyder's study? Why don't the ratios of Snyder's study fit the expected ratios of Mendel's study?
Answer:
3
Explanation:
drag each micrograph to the target that indicates the stage of mitosis or cytokinesis it shows.
Mitosis occurs after the interphase and involves four stages. After mitosis event occurs cytokinesis. The correct order is 1A, 2F, 3E, 4B, 5C, 6D.
------------------------------------------
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
First occurs duplication of the cell content, and then the separation into two new cells happens.
Mitosis occurs in only one phase.
• In the prophase, it occurs chromosomes condensation and nuclear membrane breaks.
• During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.
Each chromatid joins with a microtubule of opposites poles.
• In Anaphase, bonds between chromatids break. They separate and migrate to the opposite poles.
• In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.
• Finally, cytokinesis occurs. Through invagination of the cell membrane, the cells and their cytoplasmatic content get separated.

what is metaphase and what does it do?
Answer:
Metaphase is the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to spindle fibers. A metaphase separates duplicated genetic material that is carried in the nucleus of a parent cell and then converts it into two identical daughter cells.
Answer:
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. As metaphase continues, the cells partition into the two daughter cells.

In which organelle would the above events most likely occur?
A. Chloroplast
B. Mitochondria
C. Nucleus
D. Ribosome
PLS HELP!!
Answer:
Mitochondria
Explanation:
The organelle in which the above events most likely occur is known as the Chloroplast. Thus, the correct option for this question is A.
What is an Organelle?An organelle may be defined as a type of tiny organ or a subcellular structure that has significantly one or more specific functions in order to perform in the cell which is essential for the survival of living organisms.
The events that are demonstrated in the picture are known as the light reaction and dark reaction of photosynthesis. The light reaction of photosynthesis occurs in the thylakoid membrane of the chloroplast while the dark reaction of photosynthesis occurs in the stroma of the chloroplast.
Therefore, the chloroplast is an organelle in which the above events most likely occur. Thus, the correct option for this question is A.

A. Look at the arrows pointing toward atmospheric CO2. What are the two major sources of
atmospheric carbon?
Although the diagram is missing in this question, we can confirm that two major sources of atmospheric carbon are the use of fossil fuels and the natural ocean-atmosphere exchange.
What sources add carbon to the atmosphere?The most harmful of the sources mentioned is the one caused by humans. The burning of fossil fuels such as the oil we use to power cars and other motor vehicles adds tons of carbon into the atmosphere every day.
On the other hand, there are also naturally occurring sources for atmospheric carbon, such as the ocean or the respiration process of animals.
Therefore, we can confirm that two major sources of atmospheric carbon are the use of fossil fuels and the natural ocean-atmosphere exchange.
