When people run quickly, they can sweat profusely. Their muscles undergo movement, and the loss of energy takes place. Based on this description, in which two ways is energy conserved when people run?
Heat energy is released from the body to the surroundings.
Heat energy is taken from the surroundings to the body.
Chemical energy is converted to mechanical energy that’s used for muscle movements.
Radiant energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Answers
Answer: Chemical energy is converted to mechanical energy that’s used for muscle movements.
Heat energy is converted to mechanical energy that’s used for muscle movements.
Explanation:
According to the I law of thermodynamics, energy can neither be created cannot be destroyed but it can only change its form. In the given situation, the energy can only be conserved when it is not lost to the environment. The chemical energy is produced in the body in the form of ATP which is converted into mechanical energy to allow the movement of the muscles during running. So, chemical energy is converted into mechanical energy by this way. The heat energy when directly converted into mechanical energy to induce the movement of muscles the energy will remain conserved and will not lost to the environment.
Answer:
Chemical energy is converted to mechanical energy that’s used for muscle movements.

The extensive size of the fires that burned Yellowstone National Park in 1988 caught both land managers and ecologists by surprise. Many forests suffered intense infernos that removed virtually all vegetation. Some speculated that the park would never recover. Based on what you learned and disturbance and succession, is it likely that the park was irrevocably altered
Answers
Answer:
It is not possible that the park has been irrevocably altered.
Explanation:
The fires are part of the ecology of Yellowstone National Park, and there is a very low risk that this park will be irreversibly modified after a fire. It is scientifically proven that Yellowstone has recovered from fires in a period of thirty years and that the risk of this recovery not happening is very low. In addition, the natural fires that occur in Yellowstone are, in a way, important for the maintenance of the park's ecosystem, since they are able to break the seed dormancy that are in the soil, in addition to promoting the opening of the serine pine cones.
Seed dormancy is the difficulty of germinating that some seeds present, even in an environment with favorable conditions for germination.

than a large, open grasslands habitat?
A. The mountain has less variety in the environment.
B. The mountain would cause less fragmentation.
C. The mountain has wider range of environments.
D. The mountain has more resources.
Answers
Answer:
C. The mountain has wider range of environments.
Explanation:
Steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat The mountain has wider range of environments.
What is Grassland habitat?There are various locations and climates on earth where grassland environments can be found. Depending on where in the world they are and the type of climate there, they may also be referred to as prairies, savannahs, steppes, or pampas.
Because there are few places for animals to hide from predators in grasslands, they have developed underground burrows or grown tall enough to look over thick grasses and shrubs.
Many grasslands have been used for farming because they are suitable for raising crops and providing food for cattle. Yet, this means that grassland animals can no longer reside there.
Therefore, Steep mountain habitat have a higher rate of speciation than a large, open grasslands habitat The mountain has wider range of environments.

How are living organisms linked within an ecosystem? A. by their physical adaptations B. by what they eat C. by their size D. by their habitat
ILL GIVE BRAINLIST!!!PLEASE HELP!!
Answers
Answer:
B
Explanation:
Living Organisms in an ecosystem have a food chain or energy chain. This chain links all organisms within an ecosystem, therefore, answer B "By what they eat" should be the correct answer
Organisms are linked within an ecosystem by their physical adaptations.
What is physical adaptation?
Physical adaptations are special body parts that help a plant or animal survive in an environment.A physical adaptation is some type of structural modification made to a part of the body. A behavioral adaptation is something an animal does - how it acts - usually in response to some type of external stimulus.what is an Ecosystem?An ecosystem is made up of all species and the physical context in which they interact.Nutrient cycles and energy flows connect these biotic and abiotic components. Photosynthesis enters the system, absorbing energy and storing it in plant tissue.Animals assist in the transmission of nutrients and energy throughout the system by eating plants and each other. Both external and internal factors have an impact on ecosystems.
The availability of diverse resources within the ecosystem is determined by internal factors, whilst resource inputs are usually governed by external activities. Ecosystem mechanisms thus regulate as well as control interior elements.
so the correct answer is option A.

O The plant would not be able to grow to normal height.
O The plant would not be able to absorb water from the soil.
Answers
Answer:
The plant would not be able to grow to normal height.
Explanation:
If a plant does not develop a root cap, the plant does not allow the root to grow downwards.
Hope this helps :)
If a plant is unable to produce root caps, the plant will be unable to absorb water from the soil; this is the final option, as root caps are a specialized protective layer at the tip of plant roots that help protect the plants.
What is the significance of the root cap in the plants?The root cap contains cells that are capable of secreting slime, which helps the root to move easily through the soil, helps to maintain the proper orientation of the root tip so it can efficiently absorb water and nutrients from the soil, and acts as a barrier that protects the delicate root tip cells as the root grows through the soil.

Answers
Explanation:
populations are large, it seems fair to ask whether genetic drift is really all that important. It's true that most populations are large, but they don't necessary act large. Thus, the rate of genetic drift is not really proportional to census population size (Nc). Rather, it's proportional to something more abstract — specifically, the effective population size (Ne). In an ideal population of sexually reproducing individuals , Ne will equal Nc. An "ideal" population has the following characteristics, and most deviations will decrease the effective population size:
There are equal numbers of males and females, all of whom are able to reproduce.
All individuals are equally likely to produce offspring, and the number of offspring that each produces varies no more than expected by chance.
Mating is random.
The number of breeding individuals is constant from one generation to the next.
Essentially, anything that increases the variance among individuals in reproductive success (above sampling variance) will reduce Ne (the size of an ideal population that experiences genetic drift at the rate of the population in question). For example, consider the effect of unequal numbers of mating males and females. In an ideal population, all males and all females would have an equal chance of mating. However, in situations in which one sex outnumbers the other, an individual's chance to mate is now affected by its sex, even if all individuals within each sex have an equal chance to mate. In this situation, effective population size can be predicted by the formula Ne = 4NmNf/(Nm + Nf), where Nm is the number of males and Nf is the number of females. Figure 4 shows the relationship between Ne and Nf in a population of 1,000 mating individuals. In an ideal population, all individuals have an equal opportunity to pass on their genes. In real life, however, this is rarely the case, and Ne is particularly sensitive to unequal numbers of males and females in the population.follow me bye nice study

Extensive damage to oligodendrocytes in the CNS could result in reduced speed of nerve impulses. a breakdown of the blood-brain barrier. loss of the structural framework of the brain. inability to produce scar tissue at the site of an injury. decreased production of cerebrospinal fluid.
Answers
Answer:
Loss of the structural framework of the brain.
Explanation:
Damage to oligodendrocytes in the central nervous system leads to the loss of the structural framework of the brain. oligodendrocytes produce the insulating sheath of axons and we know that axons are the nerve fiber that conducts electrical impulses away from the neuron's cell body. Axons are the primary transmission lines of the nervous system that carries impulse throughout the body so if the oligodendrocytes are damaged then our brain did not work properly.
If oligodendrocytes are damaged, the myelin sheaths around axons can be destroyed. This can lead to a loss of the structural framework of the brain, as the axons will no longer be properly insulated. Hence option C is correct.
Oligodendrocytes are glial cells in the central nervous system (CNS) that are responsible for myelinating axons. Myelin is a fatty sheath that surrounds axons and helps to speed up the conduction of nerve impulses.
The loss of the structural framework of the brain can cause a variety of neurological problems, including:
Reduced speed of nerve impulses. As mentioned above, myelin sheaths help to speed up the conduction of nerve impulses. Without myelin sheaths, nerve impulses will travel more slowly, which can cause problems with coordination, movement, and sensation.
Increased risk of seizures. Seizures are caused by abnormal electrical activity in the brain. When the myelin sheaths around axons are damaged, it can increase the risk of seizures.
Cognitive impairment refers to a decline in thinking and memory skills. Damage to oligodendrocytes can lead to cognitive impairment, as the axons will no longer be able to function properly.
Therefore, option C) loss of the structural framework of the brain is correct.
