Answer:
Skeletal system
Explanation:
the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Answer:
I believe your best choice from the given choices above would be C) skeletal system. The bone structure within the human body, such as the rib cage for instance, provides protection for our organs and takes more impact rather than any of our organs. Without our skeletal system, we would have zero protection for our organs, increasing the chance of more internal body damage.

A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.
Which of the following actions would help the skater reach the top of the other side of the half pipe?
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.
Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.
Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.
The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.
The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.
As the heat energy is lost to the surrounding environment, the skateboard loses velocity.
Bending down by the skateboarder will provide additional energy to make up for the lost energy.
Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.

Answer:
Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.
Explanation:
Got the answer right on a quiz and reducing frictional force leads to many other contributing factors that makes the skateboarder reach the other side of the half pipe.
PLS help!!!!!! brainliest!!!! which activity produces an action potential in nerve cells?
A. mitosis
B. hormone secreation
C. release of neurotransmitters
D. exchange of ions
Answer:
Exchange of ions.
Explanation:
Release of neurotransmitters activity produces an action potential in nerve cells.
A depolarisation current causes an outburst of electrical activity, which is known as the electromotive force.
This indicates that the resting prospective moves toward 0 mV as a result of some activity (a stimulus).
A cell fires a nerve impulse when the depolarization reaches around -55 mV.

2.There can be more than one keystone species within an ecosystem.
3.Keystone species have very little importance to the balance of an ecosystem.
4.One example of keystone species in the ecosystems stem case food web are

For characteristic features of key stone species, option 1, 2 and 4 are correct.
What are keystone species ?The presence of the species whether plant or animal in an ecosystem largely influence on a given environment called as keystone species.
It affect the habitat of all living organisms, so that the ecosystem would become functionless in absence of keystone species.
On of the best example is prey-predator relationship.
Some important environmental influence of keystone species are, it affect organism's physical appearance.
There is an impact of parasites, diseases on prey and host population, act as a mutualist, absence of key stone species leads to domino effect.
For example in absence of carnivore, number of herbivores increased, hence the environment cannot support the infinite number of herbivore population.

what is cell cycle? in detail
Answer:
A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

In response to injury, cell fragments called platelets get activated to induce clotting. Activated platelets release factors that can in turn bind to specific membrane receptors on nearby cells. What type of signaling would this be considered
Answer:
Activated platelets express negative phospholipids on the exterior leaflet of their cell membrane, release vasoactive compounds, release cytokines, and release growth factors.
When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin.
Platelets contribute their hemostatic capacity via adhesion, activation and aggregation, which are triggered upon tissue injury.

What is yeast?Yeast is a fungus that is used in the process of fermentation. Yeast is a single called eukaryotic organism that comes under the fungus kingdom. Yeast cells grow very faster than animal cells. Yeast cells are used to make bread and cakes. It is also used for alcohol making and baking process.
It usually remains inactive when it is added to the food material, but when it is added to warm water or thing, it becomes active and its cells increase in size.
Thus, as a fungus, yeast is. Fermentation is created using it in many different meals. The yeast is activated throughout the bread-making process by soaking it in warm water. The flour will then rise when it is used to make bread.
