Bio Semester II Review (2 Of 3)

Based on the graph, the highest point on the curve occurs at 30 degrees. This indicates that photosynthesis is most efficient at this temperature. As the temperature increases beyond 30 degrees, the rate of photosynthesis starts to decrease. Therefore, 30 degrees is considered the ideal temperature for photosynthesis based on the information provided by the graph.

Antibiotics are effective in fighting bacterial diseases. Bacterial diseases are caused by harmful bacteria that invade the body and multiply, leading to various infections. Antibiotics work by either killing the bacteria or inhibiting their growth, allowing the body's immune system to effectively eliminate the infection. However, antibiotics are not effective against viral diseases, genetic diseases, or non-communicable diseases. Therefore, the correct answer is bacterial diseases.

The most ancestral characteristic based on the cladogram is vertebrae. This means that having a backbone is the oldest and most primitive trait among the options given. The cladogram suggests that all the other characteristics (bony skeleton, amniotic egg, egg with shell) evolved after the development of vertebrae.

Line B is going down so it shows a reverse direction, which would be returning home.

The independent variable in this graph is temperature in Celsius. This is because temperature is being manipulated or changed by the researcher to see how it affects the rate of photosynthesis. The other options given, such as "Rate of Photosynthesis" and "10, 20, 30, etc" are not the independent variable because they are the dependent variable and the values of the independent variable, respectively. The range of 0 - 1000 is just the range of values for the independent variable, but it does not define what the independent variable is.

Out of a total of 388 peas produced (117 green + 271 yellow), the number of yellow peas is 271. To find the percentage, divide the number of yellow peas by the total number of peas and multiply by 100. Therefore, (271/388) * 100 = 69.8%, which can be rounded to 70%.

The key idea of modern evolutionary thought is that there is individual genetic variation within a population. This means that individuals within a population have different genetic traits, which can lead to differences in their survival and reproductive success. This variation is important because it provides the raw material for natural selection to act upon, allowing for the adaptation and evolution of species over time.

The correct answer is "rabbits and birds." Both rabbits and birds are animals that lay amniotic eggs. Amniotic eggs are characteristic of reptiles, birds, and some mammals, including rabbits. These eggs have a protective amniotic membrane that surrounds the developing embryo, providing it with nutrients and protection. Amphibians do not lay amniotic eggs, as their eggs lack this protective membrane. Primates, on the other hand, give birth to live young and do not lay eggs.

The given characteristics of having a nucleus, cell wall, and being heterotrophic are all traits commonly associated with fungi. Fungi are eukaryotic organisms that have a distinct nucleus and a cell wall made of chitin. They are heterotrophic, meaning they obtain nutrients by absorbing organic matter from their environment. Therefore, based on these characteristics, it is likely that the cell described in the question is a fungi.

During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. As a result of this process, water and carbon dioxide are released as waste products. Oxygen is used in the process to oxidize glucose, while carbon dioxide is produced as a byproduct of the breakdown of glucose. Therefore, the correct answer is water, carbon dioxide.
