Two linebackers tackle a quarterback. One hit him with a force of 105 N and the other hit him with a force of 150 N. They are both running East. Calculate the net force acting on the Quarterback.
Answers
The net force on the quarterback when he is hit by two linebackers running eastwards is 255N.
Force is a vector quantity, we must recall that if two forces act in the same direction, we obtain the net force by adding the two forces together. If two forces act in opposite direction, we obtain the net force by subtracting the forces from each other.
Since the both linebackers are running East, the net force is obtained as; 105 N + 150 N = 255 N.

What is the end result of cytokinesis in mitosis?
Answers
The end result of cytokinesis in mitosis is the formation of two daughter cells, each having identical copies of the original parent cell's chromosomes.
What is mitosis?Mitosis is a type of cell division which results in two daughter cells that are genetically identical to the parent cell. During this process, the nucleus of the parent cell is divided into two daughter nuclei, each containing an identical set of genetic material. The daughter cells then divide further to form two new cells.
Cytokinesis is the process of cell division that occurs after the genetic material has been divided into two identical sets during mitosis. It involves the physical division of the cytoplasm, cell membrane and cell organelles into two distinct daughter cells. During cytokinesis, the membrane of the parent cell pinches inwards, forming a cleavage furrow that divides the cell into two separate, identical daughter cells. Once the division is complete, each daughter cell will have its own nucleus, cytoplasm and cell membrane, as well as a full set of chromosomes identical to those of the original parent cell.

Dozens of earthquakes hit Hawaii as the world's largest volcano erupts
On November 27, Mauna Loa erupted for the first time in nearly 40 years. Located in Hawaii, Mauna Loa is the world's largest active volcano. Volcanoes are openings or vents where lava, small rocks, and steam erupt onto the Earth's surface. Melted rock that comes up from inside the Earth and out of a volcano is lava. The Mauna Loa eruption occurred at the Moku'āweoweo summit caldera. This is a large sunken basin at the summit — or highest point — of the volcano.
Following the eruption, dozens of earthquakes swarmed the region — one of them a magnitude 4.2 quake. Magnitude is a number that characterizes the relative size of an earthquake from 1 to 9.
Remain Vigilant
Officials issued an ashfall advisory for Hawaii's Big Island and asked residents to remain vigilant. So far the eruption's lava flows pose no risk to people living downhill from the eruption, according to Hawaii's Tourism Agency.
Map showing lava flow of Mauna Loa from the years 1843 to 1984.
Image 1. The volcano's last eruption was in 1984, when it sent a lava flow close to the city of Hilo.
"At this time, lava flows are contained within the summit area and are not threatening downslope communities," said officials from the U.S. Geological Survey (USGS). The USGS is a government agency that collects information to help monitor natural hazards such as earthquakes. They warned, however, that the location and advance of lava flows can change rapidly.
The USGS's Hawaiian Volcano Observatory noted that it is set to perform flights to assess the eruption. They warned that "winds may carry volcanic gas and possibly fine ash and Pele's hair downwind." Pele's hair are thin strands of volcanic glass formed from cooling lava. The glass is sometimes carried into the air by strong winds and is sharp enough to tear skin and eyes.
Monitoring The Volcano
Mauna Loa takes up more than half of Hawaii's Big Island. It rises 13,679 feet (4,169 meters) above the Pacific Ocean, according to the USGS. The volcano is fairly active, having erupted 33 times since its first well-documented eruption in 1843. Its last eruption was in 1984 when it sent a lava flow close to the city of Hilo. After that, Mauna Loa entered its longest dormant period in recorded history. Periods of time when the volcano is not erupting, but could in the future, are volcanic dormant periods.
Scientists tracked an uptick in earthquake frequency beginning in June with five to 10 earthquakes a day. By September, the warning signs of an eruption increased. The number of earthquakes grew to around 40 a day in October.

Answers
An epidural increases the chance of having a cesarean section, the correct option is B.
An epidural is a regional anesthesia technique commonly used during labor to provide pain relief to the mother. While it effectively reduces the pain experienced during childbirth, it can also have certain effects and potential risks. One of the most common problems associated with epidurals is an increased likelihood of cesarean section.
When an epidural is administered, it can lead to a decrease in the mother's ability to feel and control her contractions. This can result in a longer labor process and potential complications, such as fetal distress or an inability to progress in labor. The correct option is B.

Answers
A synaptic cleft is a fluid-filled space between two neurons through which neurotransmitters travel. It is in this area where messages are transmitted chemically.
The synaptic cleft is a vital component of the synaptic junction, which is the point of communication between two neurons. When an action potential reaches the presynaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the postsynaptic neuron, initiating a series of biochemical events that lead to the transmission of the message. The synaptic cleft acts as a physical and chemical barrier, ensuring that the neurotransmitters are specifically received by the appropriate receptors. This process allows for precise and controlled communication between neurons.

The close genetic linkage of human pubic lice to gorilla body lice, in that hominid body hair, was lost in the Australopithecine era.
Three types of lice attack humans: head lice, body lice, and pubic lice are the basis of researchers in deepening their evolution.
Pubic lice are in a different genus from body lice and head lice. Pubic lice are the closest living relative to the gorilla louse. Although the common ancestor of humans and gorillas lived about 7 million years ago, pubic lice and gorilla lice have a much younger ancestor - around 3-4 million years ago. The most likely explanation is a shift in a host as gorilla lice adapted to life on human pubic hair. This will happen after we lose our body hair, so our head and pubic hair are in different places and before we start wearing clothes.

One friend tep away from the rock. Doe the rock move? If o, in which direction doe it move?
Answers
A rock is pushed against with great force by two friends. The forces are equally powerful, but they are moving in opposite directions. The rock is supported on top by a bulky box. Because both sides exert equal forces, the rock does not move.
An influence that has the ability to alter an object's motion is known as a force. A force can alter the velocity or accelerate a mass-bearing object. A push or a pull is an obvious way to define force. Since a force has both magnitude and direction, it is a vector quantity.
A body's tendency to alter or change its condition as a result of an external cause is referred to as force. The body can also change its size, shape, and direction when force is applied. Some examples include kicking a ball, opening and closing doors, and mixing dough.

Answers
Answer:
continental drift
Explanation:
The most likely reason for this would be continental drift. It is believed that millions of years ago our world was one giant continent. This continent began breaking apart and drifting slowly more and more as millions of years passed by, ultimately creating the seven continents we know now. This would mean that Brazil and South Africa were most likely once the exact same location or the edge of where the continent broke apart. This would explain why the same rock was found in both locations.
