The change in weather pattern caused forest to become sparse and hot weather caused the reduction of apes as they had less food and difficulty in surviving the climate.
Explanation:
In Miocene epoch volcanic mountain chains were created in Central Africa which abruptly changed the local weather.
The sea-level got drop due to global cooling of that time.
This resulted in continental drift making land connection of Africa with Eurasia.
The primates started migrating through this route.
The African forest become dry causing selective pressures in primates.
The cooler climate in Eurasia caused extinction and migration of primates to Africa in late Miocene epoch.
The hot and humid climate and less woodland caused a reduction in number of apes which were replaced by modern world monkeys.
Answer: True
Explanation:
The VPL stands for the ventral posterolateral nucleus, the thalamic nucleus received the information from lemniscus and it displayed its sensory information into the primary cortex in the brain. In the pathway the trigeminal lemniscus conveyed the vibration and the sense of the touch in the nucleus of thalamic where, it send the data or information in the body.
Answer:
<u>No, there is no control group.</u>
Explanation:
To test various theories, experiments are usually conducted under a number of different conditions. Several considerations must be established when planning studies to ensure reproducibility, accuracy, and validity of findings.
For example, while controls are kept constant, or unmanipulated. Also, separate independent variables are strictly altered and analyzed - this guarantees validity and may show whether external influences affected the experiment. Here the variable being altered or measured is the food, and the resultant weight is the factor being observed.
Answer:
Peahens often choose males for the quality of their trains -- the quantity, size, and distribution of the colorful eyespots. Experiments show that offspring of males with more eyespots are bigger at birth and better at surviving in the wild than offspring of birds with fewer eyespots.
Complete question:
You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Check All That Apply
- The swing will move farther away from the tree trunk.
- The swing will move up. away from the ground.
- The swing will remain in its original position.
- The swing's ropes will become embedded in the branch.
Answer:
The swing's ropes will become embedded in the branch.
Explanation:
The trunk or branch strangulation sadly occurs very often. When people tie a young tree with different materials, such as a rope, or a cable, or a wire, and leave it there, the leash will eventually strangulate the tree.
Strangulation occurs because the tree keeps growing, applying pressure on the leash. The vascular system is in the trunk perimeter under the crust. Through the years, the pressure increases, the trunk is even more strangulated, and the vascular system is affected. One of the first and principal effects of strangulation is the increase in the trunk or branch diameter over the leash. This diameter change is because elements of the sap can not go back to the roots and keep near the strangulation. At this point, there are two options:
- The tree can sort this by including the leash in its tissues, surrounding and absorbing it, and keep growing normally
or
- The vascular system is so affected that the tree can not sort this problem and so, those parts of the tree located over the leash dye.
<em>In the exposed example, it seems that the tree could make it and included the swing's ropes in the branch. </em>
