what protects the brain by acting as a shock absorber and removing waste?
a. durameter
b. cerebrospinal fluid
c. arachonid membrane
d. cranium
Answers
Cerebrospinal fluid protects the brain by acting as a shock absorber and removing waste. It is located in the subarachnoid space, which is the area around and inside the brain and spinal cord that is made up of the pia mater, the arachnoid mater, and the ventricular system.
Cerebrospinal fluid serves as a shock absorber for the central nervous system and serves as the brain's major cushion within the skull. Additionally, CSF eliminates trash from the brain and circulates chemicals and nutrients filtered from the blood. The dural venous sinuses, a drainage system found in the dura mater, allow blood to exit the brain and cerebrospinal fluid to re-enter circulation. The dura-mater, a thin membrane adhering to the surface of the brain and spinal cord, is connected to the pia-mater by thin, elastic fibres known as the arachnoid. Protection and structure are the primary functions of the skull and the meninges that surround it.

The diagrams show the sequence of events that occur as an action potential is conducted along an axon.
Drag each label to the appropriate location on the diagrams.
Answers
Action potential, Axon, Depolarization, Repolarization An action potential is an electrical signal that is conducted down the axon of a neuron. It is initiated when the membrane potential of the axon reaches a certain threshold and is followed by a series of events that result in the propagation of the signal. The diagrams show the sequence of events that occur as an action potential is conducted along an axon.
The first step is depolarization, in which the membrane potential of the axon reaches the threshold level and is exceeded. This causes the voltage-gated sodium channels to open, allowing sodium ions to enter the axon. This depolarizes the membrane and causes an influx of positively-charged ions. This depolarization spreads in an all-or-none fashion along the axon.
The second step is repolarization, which is the return of the membrane potential to its resting state. This is accomplished by the opening of voltage-gated potassium channels, which allow potassium ions to leave the axon. This causes the membrane potential to become more negative, restoring it to its resting state.
The action potential then continues along the axon in a “wave” of depolarization and repolarization. This process allows the action potential to travel along the axon, allowing the neuron to transmit signals to other neurons.

The unit mentions that the timber industry was devastated by chestnut blight. What other industries might be harmed by this infestation? Explain.
Answers
Answer:
hope this helps :D
Explanation:
1. Factors that make wildfires a problem or unlikely in an area depend on several factors, such as the climate, weather patterns, vegetation types, topography, and human activities. For example, areas with dry, hot summers and strong winds are more likely to experience wildfires. Conversely, areas with wetter climates, frequent rainfall, and less flammable vegetation are less prone to wildfires.
2. Controlled burns can be a good idea in some circumstances. These controlled fires can help reduce the buildup of dead plant material that can fuel more severe wildfires. They can also help promote the growth of new plants and improve the overall health of an ecosystem. Controlled burns are often used by land managers to reduce the risk of more destructive wildfires and to restore natural habitats.
3. In the case of a wildfire, it is easiest to eliminate the fuel source. This can be done by clearing vegetation, creating fire breaks, and reducing the amount of dead plant material on the forest floor. However, this is often difficult to do in practice, especially in remote or rugged areas.
4. Motivations for arson in a forest can vary widely, ranging from revenge, financial gain, or mental illness. To reduce arson in forests, a multi-pronged approach is needed, including education and outreach programs, stronger enforcement measures, and increased public awareness about the dangers of wildfires.
5. The chestnut blight epidemic devastated the timber industry, but other industries could also be affected by similar infestations. For example, the maple syrup industry could be impacted by invasive insects that attack maple trees, and the citrus industry could be harmed by diseases that affect citrus crops. These infestations could have far-reaching economic impacts, including job losses and reduced revenue for local communities.

Which term describes the two groups of plants that do not need water to reproduce?
Paleozoic plants
cotyledons
spermatophytes
embryophytes
Answers
Spermatophyte is the term that describes the two groups of plants that do not need water to reproduce.
Water is not necessary for fertilization or reproduction in spermatophytes since siphonogamy occurs where the male gametes are transported via the pollen tube. Siphonogamy is a condition in plants in which the male cells are transferred to the eggs via the development of pollen tubes. Seed plants are often siphonogamous.
Spermatophyte is a group of plants including gymnosperms and angiosperms. Gymnosperms are cone-bearing plants, while angiosperms are flower-bearing plants. They reproduce sexually through the means of seeds.
Spermatophytes initially develop pollen for fertilization. The pollen is then transferred to the ovary via pollen tubes, resulting in the production of seeds. Pollen is transferred by vectors like air, any insect, etc. Thus, they do not require water for reproduction.

B The heart muscle relaxes to reduce

C The heart muscle contracts to increase

the volume in the heart chambers.
Answers
Answer:
A
Explanation:
The correct answer is A: The heart muscle contracts to reduce the volume in the heart chambers.
When the heart muscle contracts, it creates pressure that pushes blood out of the heart and into the arteries. The contractions are initiated by electrical signals that spread through the heart muscle, causing the heart muscles to contract in a coordinated manner. During the contraction, the ventricles (the two lower chambers of the heart) reduce in volume, which forces blood out of the heart and into the blood vessels. This process is known as systole.
After the heart has pushed the blood out, it relaxes to allow the blood to fill the heart again. During this relaxation phase, known as diastole, the heart chambers increase in volume, allowing blood to flow in from the veins. This cycle of contraction and relaxation allows the heart to pump blood efficiently and effectively throughout the body.

What has the greatest influence on windspeed
Answers
The primary factor affecting wind speed is the pressure gradient between high and low pressure locations.
What affects the wind's velocity?
The difference in pressure between high- and low-pressure zones is known as a pressure gradient.
The pressure gradient and wind speed are intimately correlated, so as the pressure gradient (i.e., change in pressure) grows, the wind speed at that place also increases.
What influences wind speed the most?
Because the sun heats the Earth differently in different regions, creating pressure differences, wind is a result of a horizontal variation in air pressure, therefore the sun is the primary source of most winds.

how does the genetic diversity of a modern corn field compare to the genetic diversity of a population of teosinte?
Answers
The genetic diversity of a modern corn field is generally much lower than the genetic diversity of a population of teosinte.
The Teosinte is the wild ancestor of modern corn, and it is native to Mexico and parts of Central America. Teosinte populations have a high degree of genetic diversity, with many different varieties that have adapted to a wide range of environmental conditions and have evolved in response to different selection pressures.
The "modern-corn" is a highly uniform crop that has been selectively bred for specific traits such as high yield, disease resistance, and uniformity of appearance.
The loss of genetic diversity in modern corn has several potential implications. For example, it may make corn more vulnerable to diseases and pests, as there are fewer genes that confer resistance to these threats.
