A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of: Sympatric speciation. Iterative evolution Evolutionary drift Genetic drift Lamarckian evolution
The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.
Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.

The major factor that will determine how many motoneurons will die during normal development is
Group of answer choices
exercise
target size
cell adhesion molecules
death genes
The major factor that determines how many motoneurons will die during normal development is target size. Target size refers to the size and number of muscle fibers that a motoneuron innervates. During development, motoneurons compete for the limited trophic factors produced by their target muscles.
In the early stages of development, there is an overproduction of motoneurons. As they grow, motoneurons form connections with their target muscles. The muscles produce trophic factors, such as nerve growth factor (NGF), which support the survival and growth of motoneurons. However, the amount of trophic factors produced is limited, resulting in competition among motoneurons for these essential resources.
Motoneurons that successfully connect to target muscles and receive adequate trophic factors will survive, while those that fail to do so will undergo programmed cell death, or apoptosis. This process is regulated by death genes, which control the expression of proteins involved in apoptosis. As a result, only the motoneurons that have established functional connections with their target muscles will survive, ensuring proper neural circuit formation and function.
In summary, target size is the major factor determining how many motoneurons will die during normal development, with death genes playing a crucial role in regulating apoptosis. The competition for trophic factors produced by target muscles ensures that only functional motoneurons survive, ultimately contributing to the proper formation and functioning of neural circuits.

The ratio of alcohol to total blood volume is the blood alcohol concentration.
The blood alcohol concentration (BAC) is the ratio of alcohol to total blood volume. It is used to measure the amount of alcohol in a person's blood. BAC is measured by taking a sample of blood from a person's vein and testing it for alcohol content. The results of a BAC test are expressed as a percentage of alcohol in the blood.The BAC is measured in units of alcohol per 100 milliliters of blood. A BAC of 0.01% means that there is one part of alcohol in 10,000 parts of blood.
How much alcohol you've consumed, your weight, your gender, and how quickly you're drinking, might have an impact on your blood alcohol concentration. Your blood alcohol content will increase as you consume more alcohol. If you consume too much alcohol, your blood alcohol level may rise dangerously high, which could cause serious illness or even death.
Alcohol that is consumed is absorbed into the bloodstream and distributed throughout the body. Because alcohol is a central nervous system depressant, it has an impact on your brain. This indicates that it causes a slowdown in brainfunction.
