In addition to the appearance of the antifreeze gene, icefish have also been found to have DNA sequences similar to the DNA sequences in hemoglobin genes of other fish species. However, these DNA sequences are not complete and therefore not functional in icefish. This evidence makes The Greatest Plant Skit - Anonamix - The Anonymous Mix Volume 2 - Sea Of Green (CDr) likely that.
Green sea slugs are animals that live in water and have developed the ability to produce their own chlorophyll. These creatures can also pass this ability to make chlorophyll to their offspring. Once the offspring have one meal of algae, they are able to make food using sunlight.
This one meal provides the baby slugs with the chloroplasts needed to make use of the chlorophyll, and they are able The Greatest Plant Skit - Anonamix - The Anonymous Mix Volume 2 - Sea Of Green (CDr) produce their own food in the future. The best explanation for why sea slugs are able to pass on this ability to make food to their offspring is that. The diagram below represents one of many microscopic air sacs in a human lung.
The alveolus air sac is the place where oxygen O2 and carbon dioxide CO2 move into or out of the blood, as represented in the diagram. Which statement best explains why these gases are able to move in the directions shown in the diagram? The CO2 moves out of the capillary and into the alveolus to make more room for the blood to carry O2. The O2 is needed by the cells, so it is actively transported into the blood.
The CO2, which is not needed, is actively transported out of the blood. The blood coming to the lungs is low in CO2 and high in O2, so the gases each diffuse from a lower to a higher concentration in this area. The blood coming to the lungs is high in CO2 and low in O2, so the gases each diffuse from a higher to a lower concentration in this area.
During the process of chromosome replication, a genetic error occurs. As a result, a sequence of events occurs as described below. The evolutionary tree below represents possible relationships between several species of plants.
According to the tree, species B and C are more closely related to each other than to species A. Which gel electrophoresis diagram would best support this statement? In addition to analyzing DNA, what other evidence could be used to best support the evolutionary relationship between species B and C?
In his journey to the Galapagos Islands, Charles Darwin was amazed by the variation in the characteristics of plants and animals he encountered. In any habitat, food can be limited and the types of foods available may vary. One year, there was no rain on these islands. Many plants failed to bloom and produced no new seeds.
This left mostly large, tough seeds for the finches to eat. The different tools such as spoons, chopsticks, or pliers used during The Beaks of Finches laboratory activity represented variations in. A student completed a lab activity that demonstrated the connection between pulse rate, heart rate, and fl ow of blood during exercise. She left her class wondering if there is a connection between breathing rate and exercise.
With the help of her track coach, she conducted an investigation to try and find an answer to her question. In the investigation, the respiratory rates of thirty athletes were measured before any exercise. To measure their rates, they counted the number of times they took a breath in The Greatest Plant Skit - Anonamix - The Anonymous Mix Volume 2 - Sea Of Green (CDr) minute. Then, they ran one lap around the track, and their respiratory rates were determined again.
Finally, they ran two laps around the track and checked their respiratory rates one last time. All of their data were recorded, and the averages were calculated.
The data table shows the information obtained in this investigation. During this activity, what was the purpose of finding the respiratory rates of the students at rest? Played 1 times.
