The figure shows two water molecules held together by a/an
bond. (arrow tip)
A. covalent
B.hydrogen
C.ionic
D.van der Waals
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
the path of a nerve signal involved in kicking a ball .When and where do you motor or sensory nerves fire?
Answer:
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.

1. In the overall energy transformation in photosynthesis, the energy of ____ is converted to the energy of ____.
2. In the overall energy transformation in cellular (aerobic) respiration, the energy of ____ is converted to the energy of ____.
3. In the overall energy transformation in fermentation, the energy of ____ is converted to the energy of ____.
Answer: 1. Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.
2. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
3. Any chemical process that yields energy is known as a catabolic pathway. Cells release the energy in those organic molecules by breaking them down. Through cellular respiration and fermentation, those bonds are broken releasing the potential energy of organic molecules into kinetic energy that cells use to do work.
Explanation:
how are active faults and inactive faults similar
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.
Explanation:
HELP WILL GIVE BRANLIEST
Answer:
Respiration removes oxygen from the atmosphere, and photosynthesis puts oxygen into the atmosphere.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Tell the story of the predator/prey loop.
If the owl population goes up, then ...
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.

Explanation:
Analysis of _____ can be used for very precise personal identification. It is even used in anthropology to identify the bones of a deceased person.
odontology
DNA
long bone measurement
fingerprinting
Answer:
DNA
Explanation:
The DNA of a human being is very unique as each human has a different sequence of it. This allows for it to be used for very precise identification of humans such that it has been used to solve crimes.
DNA is also present in every cell in the human body which is why it is useful in anthropology as well. Anthropologists can simply extract cells from a bone and through the DNA extracted, find out more about a dead person.
Therefore, DNA is the answer.

Which of the following occurs when the moon is closest to the Earth?
periapsis
apogee
revolution
ellipse
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.
What is 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.

ATP hydrolysis is needed for active transport. Which of the following requires the transfer of the terminal phosphate group of ATP?
Aquaporins
Carrier proteins
Channel proteins
Sodium potassium pump
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.
