Muscles cannot function without ATP. Review your knowledge of ATP by answering the following questions. ATP molecules store and release .
Answer:
The ATP molecule store energy and releases it.
Explanation:
The ATP stands for adenosine triphosphate. The ATP provides energy in cellular processes of the body. The attachment of terminal phosphate group to molecule helps ATP molecule to store energy. The energy stored at one location is transferred to other cell. The transferred energy is released to perform biochemical reactions.
ATP, or Adenosine triphosphate, stores and releases energy that's essential for cellular processes, including muscle contraction. It stores energy in the bonds between its three phosphate groups. When these bonds are broken, energy is released, providing fuel for activities within the cell, like muscle contraction.
Explanation:Adenosine triphosphate, more commonly known as ATP, plays an essential role in energy transfer within cells. ATP molecules are responsible for storing and releasing energy. This responsibility makes them absolutely critical for a multitude of cellular processes, including muscle contraction, hence why muscles cannot function without ATP.
ATP stores energy in the bonds between its three phosphate groups. When one of these bonds are broken, through a process called hydrolysis, energy is released. This released energy is then used to fuel various activities in the cell, including the contraction of muscles.

The diagram shows the layers of earth. Convection currents in which region influence the movement of tectonic plates?
Answer:
C
Explanation:
This layer is called the mantle and is formed of semi-plastic rocks (liquid enough to churn but the rocks are not really melted because of the enormous pressure of the overlying crust above). The layer is heated from below by the core that is hotter, The hotter mantle rises as it gets less dense while the cooler mantle at the upper layers sinks because it is denser. These convections drag with them the continental plates of the crust.
Convection currents in the Earth's mantle are responsible for the movement of tectonic plates. These currents result from the heating, rising, cooling, and sinking of mantle material. The movements of these plates result in phenomena such as earthquakes and volcanoes.
Explanation:The convection currents responsible for the movement of tectonic plates occur in the mantle region of the Earth. This is the layer between the crust and the outer core that accounts for about 84% of Earth's volume.
In this region, heat from the Earth's interior causes the material in the mantle to heat up and become less dense, causing it to rise. Once it reaches the top of the mantle and comes close to the Earth's crust, it cools, becomes denser, and sinks back down. This cycle is repeated over and over to create convection currents which provide the force that ultimately causes the movement of the tectonic plates.
These moving plates are responsible for geologic phenomena such as earthquakes, volcanoes, and mountain building. This complexity of plate tectonics is a fundamental concept in geology, highlighting the dynamic nature of our planet.

describe two properties of an exchange surface that would facilitate rapid diffusion rates
molecules and gaseous
The diffusion rate across an exchange surface is dictated by the extent of the concentration gradient and the surface area and thickness of the plasma membrane. A higher concentration gradient and larger surface area promote rapid diffusion, whilst a thicker plasma membrane slows down diffusion.
Explanation:Two properties of an exchange surface that would facilitate rapid diffusion rates are the extent of the concentration gradient and the surface area and thickness of the plasma membrane.
The extent of the concentration gradient is a key determinant of the diffusion rate. The greater the difference in concentration between two regions, the faster diffusion occurs. On the other hand, when the distribution of the material approaches equilibrium, the diffusion rate tends to decrease.
The surface area and thickness of the plasma membrane also affect the rate of diffusion. A larger surface area enables more materials to diffuse simultaneously across the membrane, thereby increasing the diffusion rate. Conversely, a thicker membrane inhibits the passage of materials, leading to a slower diffusion rate. This principle is applied in cells, where surface area-to-volume ratios are used to predict which cell(s) might eliminate wastes or procure nutrients faster by diffusion.

This energy comes from moving object, or objects that have stored energy. * sound energy chemical energy electrical mechanical
Motion energy, or the more common term, mechanical energy is the energy stored in objects.
The more an object moves faster, the more energy is stored. Some examples of motion energy include wind, a flowing river, a moving car, or a person running.
Final answer:
Mechanical energy is the energy associated with moving objects or storing energy, such as in kinetic or potential forms. Other forms like chemical, sound, and electrical energy can be transformed into mechanical energy. A car's movement exemplifies kinetic energy, while a compressed spring showcases potential energy.
Explanation:
The question refers to energy that comes from moving objects or stored energy sources. This type of energy is commonly known as mechanical energy, which is the sum of kinetic and potential energy in an object. Kinetic energy is the energy of motion, while potential energy is stored energy that is ready to be converted into other forms. For instance, a moving car has kinetic energy, and a compressed spring has potential energy.
Other forms of energy mentioned include sound energy, which involves the vibrations of matter; chemical energy, associated with the arrangement of atoms in molecules such as in food or fuel; and electrical energy, coming from the movement of electrons. Each of these forms of energy can be converted from one to another, like chemical energy converting to mechanical to power a car, or electrical energy converting to light in a bulb.
Understanding these forms of energy and their conversion is essential. For example, when you use a battery, it releases chemical energy which is then converted into electrical energy to power devices. Similarly, when you speak, your vocal cords vibrate to produce sound energy.
A purebred y’all plant crossed with a purebred short plant. All F1 offspring are tall. Is the allele for tallness dominant or recessive
dominant because if it wasm't 1 would come out short
Final answer:
The allele for tallness is dominant as it is expressed in the phenotype of all F1 offspring resulting from the cross between a purebred tall plant and a purebred short plant.
Explanation:
If a purebred tall plant is crossed with a purebred short plant and all the F1 offspring are tall, this indicates that the allele for tallness is dominant. This is because the tall characteristic is visible in the presence of both a tall allele and a short allele within the genotype of the offspring. From Mendel's work, we know that when describing genetic crosses, the dominant factor is represented with a capital letter (T for tall) and the recessive factor is represented by a lowercase letter (t for short). In this scenario, the plants with the genotype TT or Tt will be tall, and plants with the genotype tt will be short. Assuming the purebred tall parent had a genotype of TT and the purebred short plant had a genotype of tt, all the F1 offspring would have a genotype of Tt, expressing the tall phenotype because the dominant allele for tallness 'masks' the recessive short allele.
what is the principal source of dissolved substances in the ocean
weathering
outgassing
infiltration
vaporation
Pretty sure it’s weathering but not 100%
Answer:
infiltration
Explanation:
As Na and Cl make up much of the dissolved common salts found in the ocean waters, the element in the earth's crust can be easily be dissolved in the rain and river and get carried away from the runoff of the river. Infiltration is process by which water on the ground enters the soil. The porosity of the soil particles on land water determine the infiltration capacity and thus are a major source of dissolved sediments in water bodies. Also, rainfall influences this rate of sediment flows in water all the organic and inorganic matter in the soil is mainly composed and collected from the rain and discharge rate of the soil. Weathering produces mass wasting and erosion of the landforms from the above and thus indirectly related to the dissolved content.Ponds are ______.

How many population(s) can have the same species name
Answer:
A population is all the organisms that both belong to the same species and live in the same geographical area. A species is defined as a group of organisms capable of interbreeding and producing fertile offspring. There can be multiple populations of one species but a population only consist of one species.
Explanation:
A population consists of all individual organisms of the same species living in a specified area.
A population refers to all individual organisms of the same species living and interacting in a defined area.
For example, all the angelfish living in a specific part of the ocean constitute the angelfish population.
The number of populations with the same species name can vary from a few individuals to millions, depending on the species and its habitat.
