A person sees a ball and kicks it, in part because of actions of the nervous system. Using the parts of the nervous system listed, describe the path of nerve impulses that cause the person to (1) see the ball and (2) kick the ball.
Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles

The graph below shows the averaged sunspots from 1610 to 2007. The graph shows sunspot number on the y axis and years 1600, 1650, 1700, 1750, 1800, 1850, 1900, 1950, and 2000 on the x axis. The graph rises and falls in a cyclic order in gaps of approximately 10 years. The number of sunspots observed in 1610 was 40, in 1650 it was 5, in 1700 it was 10, in 1750 it was 90 and the number of sunspots in 1800 was 50. The number of sunspots observed in 1850 was 130 and the number of sunspots in 1900 was 10. The number of sunspots observed in 1950 was 150 and the number of sunspots observed in 2000 was 30. Based on the graph, which of these conclusions is correct? Some of the previously warm regions became colder from 1650 to 1700. Some of the previously cold regions became warmer from 1600 to 1700. Some of the previously warm regions became warmer from 1610 to 1700. Some of the previously cold regions became colder from 1900 to 1950.
Answer: Some of the previously warm regions became colder from 1650 to 1700
Explanation: I got it right on the test
According to the graph, the number of sunspots decreased from 1650 to 1700. That means the correct option is A.
What is a sunspot?The areas of the sun where the magnetic field of the sun is 2500 times more than the Earth. In these areas, the magnetic field is more than anywhere else on the surface of the sun.
Near the area of a sunspot, there is a small amount of energy output from the sun. UV rays from the sun also increase at a high sunspot activity. This increase in UV radiation causes dramatic effects on the atmosphere of the Earth.
The more number sunspots are observed, the more energy will be delivered to the earth. This increase in the energy delivered to the earth would result in an increase in the overall global temperature.
According to the graph, the number of sunspots observed decreased from 40 to 5 and increased slightly from 5 to 10 from 1610 to 1700. So, the statement says that some of the warm regions would become colder from 1650 to 1700.
Therefore, the correct option is A.

They rely on fire as part of their renewal is common in grasslands, dry woodlands, and shrublands.
Grasslands, dry woodlands, and shrublandsTropical Grassland, Savanna & Shrubland is dominated by grasses and shrubs, with or without scattered trees. Some occur in climates too dry for the forest; others depend on soil conditions or fire, or both, rather than climate. The structure is a single, major grass or shrub stratum, or a mix of the two, with trees typically <10% cover, rarely with bare ground.Thus, we can conclude that grasslands, woodlands, and shrublands depend on fire they have these common characteristics.

The hormone that regulates water reabsorption by the kidneys Group of answer choices only increases water permeability in certain portions of the kidney tubules. increases water permeability throughout the kidney tubules. only decreases water permeability in certain portions of the kidney tubules. decreases water permeability throughout the kidney tubules.
Answer: increases water permeability in certain portions of the kidney tubules.
Explanation:
The proximal convoluted tubule is the site in nephron where selective reabsorption of water and electrolytes like sodium and potassium ions occurs. From there water and other substances are reabsorbed and reenter into the circulation. This cause an increase in blood pressure and blood volume. Only the cells of the proximal convoluted tubule are permeable for this reabsorption process and they are stimulated by a hormone named as aldosterone.

Variation in great horned owl body size due to food supply can / cannot be acted on by
natural selection.
Answer:
Variation can be acted on by natural selection.
Explanation:
Variation are the difference that exist in the organism in terms of the body size and can be acted upon by natural selection.
Natural selection could act on the owl body size, favor the selection of owl with small body size especially when resources available are limited and can only sustain small number of individuals leading to availability of owl with small body size in such area and a gradual reduction in the number of owl with large body size.

A population of large predators in an ecosystem has been trapped and removed from the area. How would this event most likely change the food web in this ecosystem?
As per the given scenario, the number of small predators will decrease and the number of herbivores will increase. The correct option is C.
A reduction in the pressure of large predators on herbivores would follow from their disappearance.
Since there would be less threats to them from predators, the population of herbivores would probably rise.
The effect would be a reduction in the population of tiny predators, which may have previously depended on the huge predators as a food source.
As a result of this adjustment, the ecosystem's small predator population would decline while the population of herbivores would expand.
Thus, the correct option is C.

mechanisms of pesticide resistance shown in the graphic.
A)Insects that are sensitive to the pesticide all die out after the first
application, leaving only the resistant insects in the population,
B)When insects are exposed to the pesticide, some will develop a mutationmaking it resistant. Only these insects survive in the next generation
C)The first generation has an insect with a gene responsible for resistance toa pesticide. This allows it to survive the pesticide application and reproduce
D)The insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this
trait become more prominent in the population
E)As a population of insects is exposed to a pesticide, those susceptible to
the pesticide will die out of the population, leaving those with a resistance
to survive and reproduce, becoming more common in the population
