Answer:

Below : )

Explanation:

Well, in most cases if the predator population rises most likely the prey population decreases this is because there is a big population of the predator which allows more of them to eat the prey so the prey decreases. Now when the prey decreases this again affects the predators because now the predators are limited to food so that causes many of them to decrease.

In this scenario, if the owl is the predator, as the population rises, its prey will decrease.

If the owl is the prey, the predators would most likely increase.

Answer:

Active faults are structure along which we expect displacement to occur. By definition, since a shallow earthquake is a process that produces displacement across a fault, all shallow earthquakes occur on active faults. Inactive faults are structures that we can identify, but which do no have earthquakes.

Answer:

b) Hydrogen

Explanation:

The figure shows the hydrogen bonding of two H2O molecules. The red atom is Oxygen which is δ−, and the white atom is Hydrogen which is δ+, this is determined by their electronegativity. H2O molecules can form hydrogen bonding when the Hydrogen atom bonds through hydrogen bonding to the oxygen atom and vice versa.

This type of bond is an intermolecular bond

Answer:

periapsis

Explanation:

Periapsis is the point when the orbiting object comes the closest to the thing it is orbiting around; for example, the moon is at periapsis when it is closest to the Earth.

Moon revolves around the earth in an elliptical pathway. At some point moon approaches earth at its closest point.  This point is called perigee. This closest approach is called periapsis.

Moon is the only satellite of earth. Moon revolves around earth along with rotating about its own axis. Earth have a gravitational pull into moon and this force will be different at different point of orbital revolution.

Moon's orbit is elliptical. The points of farthest approach to earth is called apogee  and the closest point is called perigee. Every planet will have an apogee and perigee with sun as for earth and also with their  satellites.

The farthest approach of moon from the earth is called apoapsis and the closest approach is called periapsis. Periapsis is also called perilunar, parselene, perilunar etc. Hence, option A is correct.

The purpose of technology is to solve problems and improve various aspects of human life. Option C.

The purpose of technology is multifaceted and encompasses various objectives.

However, at its core, technology is developed to address challenges, solve problems, and enhance different facets of human existence. Whether it is improving efficiency, increasing productivity, advancing communication, or creating innovative solutions, technology aims to provide practical and tangible benefits.

Technological advancements enable us to overcome obstacles and improve the quality of life.

From medical technologies that diagnose and treat diseases to renewable energy sources that combat climate change, technology plays a pivotal role in finding solutions to complex problems. It empowers us to tackle issues in areas such as healthcare, transportation, agriculture, education, and environmental sustainability.

Furthermore, technology drives scientific discoveries and innovation. It provides scientists with tools and methodologies to conduct research, gather data, and analyze information, leading to new insights and understandings of the world.

Technological advancements in fields like computing, artificial intelligence, and genetic engineering have opened up new frontiers for exploration and scientific breakthroughs.

While technology can be used for political advocacy, social mobilization, and improving governance processes, these are additional applications rather than its fundamental purpose.

The primary aim of technology is to address challenges, solve problems, and enhance human experiences in various domains. It serves as a catalyst for progress and development, shaping the way we live, work, communicate, and interact with the world around us. SO Option C is correct.

The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have  a negative effect on aquatic species. The negative effects include:

Toxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.

The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female  aquatic species such as reef fish.

Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

Answer:

I would think Channel proteins but I could be wrong

The sodium potassium pump is the only one of the options that requires the transfer of the terminal phosphate group of ATP.

Active transport is the process of moving molecules across a cell membrane against their concentration gradient. This requires energy, which is provided by ATP hydrolysis.

Aquaporins are water channels that allow water to move through the cell membrane without requiring energy. Carrier proteins and channel proteins are also involved in passive transport, which does not require energy.

The sodium potassium pump is an example of active transport. It uses the energy from ATP hydrolysis to move sodium ions out of the cell and potassium ions into the cell. This creates an electrochemical gradient, which drives the movement of other ions and molecules across the cell membrane.

The sodium potassium pump is essential for maintaining the electrical potential of the cell membrane. It is also involved in the transport of nutrients and waste products into and out of the cell.

Explanation:

the path of a nerve signal involved in kicking a ball .When and where do you motor or sensory nerves fire?​

The nervous system is made up of two parts. Each part contains billions of neurons. The first part is the central nervous system. It contains the brain and spinal cord, which is a fibrous, ropelike structure that runs through the spinal column down the middle of the back.

The other part is the peripheral nervous system. It consists of thousands of nerves that connect the spinal cord to muscles and sensory receptors. The peripheral nervous system is responsible for reflexes, which help the body avoid serious injury. It's also responsible for the fight or flight response that helps protect you when you feel stress or danger.

Let's examine an individual neuron up close.

Here is a peripheral nerve. Each one of the nerve bundles, or fascicles, contains hundreds of individual nerve.

Here's an individual neuron, with its dendrites, axon, and cell body. The dendrites are tree-like structures. Their job is to receive signals from other neurons and from special sensory cells that tell us about our surroundings.

The cell body is the headquarters of the neuron. It contains the cell's DNA. The axon transmits signals away from the cell body to other neurons. Many neurons are insulated like pieces of electrical wire. The insulation protects them and allows their signals to move faster along the axon. Without it, signals from the brain might never reach muscle groups in the limbs.

Motor neurons are responsible for voluntary control of the muscles all over the body. The operation of the nervous system depends on how well neurons communicate. For an electrical signal to travel between two neurons, it must first be converted to a chemical signal. Then it crosses a space about a millionth of an inch wide. The space is called a synapse. The chemical signal is called a neurotransmitter.

Neurotransmitters allow the billions of neurons in the nervous system to communicate with one another. That's what makes the nervous system the body's master communicator.
