It requires cellular energy for the movement of the particles. The larger molecules needs energy to move across concentration gradient.
1) One difference between carbohydrates and lipids is that A) Lipids will dissolve in water but not carbohydrates. B) Carbohydrates will dissolve in water but not lipids. C) Carbohydrates contain hydrogen, carbon, and oxygen and lipids do not. D) Lipids contain hydrogen, carbon, and oxygen and carbohydrates do not.
Final answer:
Carbohydrates and lipids both contain carbon, hydrogen, and oxygen, but differ in that carbohydrates will dissolve in water while lipids will not due to their nonpolar hydrophobic characteristics. So the correct option is B.
Explanation:
One difference between carbohydrates and lipids is that carbohydrates will dissolve in water but not lipids. Lipids contain the same elements as carbohydrates, which are carbon, hydrogen, and oxygen. However, lipids are predominantly composed of hydrocarbon chains that are nonpolar and hydrophobic, meaning they do not dissolve well in water, whereas carbohydrates are generally polar molecules which can dissolve in water.
Both lipids and carbohydrates serve as sources of energy. However, they differ in how they store and provide this energy. Carbohydrates generally provide quick energy, while lipids store energy for long-term use. The solubility of lipids is different than that of carbohydrates due to their physical structure and the presence of fewer polar functional groups. Lipids are more soluble in organic solvents, like dichloromethane, due to their nonpolar nature.

ATP becomes ADP through hydrolysis, which involves the breaking of a high-energy phosphate bond by the addition of water, releasing energy. This reaction is reversible; ATP can be regenerated from ADP and phosphate using energy from cellular respiration or photosynthesis.
Explanation:ATP (adenosine triphosphate) becomes ADP (adenosine diphosphate) through a process called hydrolysis. This involves the addition of a water molecule (H2O) to ATP, which results in the breaking of one of its high-energy phosphate bonds. The reaction releases energy that the cell can use for various functions. Specifically, the equation for this reaction is ATP + H2O → ADP + Pi + energy. The inorganic phosphate released is denoted as Pi.
Cells can regenerate ATP from ADP and Pi by reversing the hydrolysis reaction. This reverse process, called phosphorylation, requires an input of energy. It can occur during cellular respiration or photosynthesis, where the energy is sourced from the breakdown of food or absorption of sunlight, respectively. The reverse equation is often expressed as ADP + Pi + free energy → ATP + H2O.
Those phosphate bonds in ATP are high energy because the phosphate groups have negative charges that repel each other. It takes energy to keep them together, and when the bond is broken, energy is released. This is why ATP is often referred to as the energy currency of the cell.

Water can absorb more heat than land, but water does not increase in temperature as fast because it has a high A) polarity. B) surface area. C) heat capacity. D) surface tension.
Answer;
-Heat capacity
-Water can absorb more heat than land, but water does not increase in temperature as fast because it has a high heat capacity.
Explanation;
-Heat capacity is the capability of water to absorb heat without undergoing an increase in temperature. For water to increase in temperature, its molecules must be made to move faster within the water; which requires breaking hydrogen bonds that absorbs heat.
a behavior in which animals move toward or away from a light source.
Answer: Phototaxis
Explanation: Phototaxis is the phenomenon by which locomotory movement of the organism occurs towards or away from the stimulus of the light.
This is advantageous for the phototropic organism as they can move efficiently towards the sunlight which helps them to make food by the help of sunlight and other substances.
The phototaxis is called positive if the movement is towards sunlight and negative if the movement is against light.
How does the cell membrane help cells maintain homeostasis
The cell membrane maintains homeostasis by controlling the movement of substances in and out of the cell, allowing cells to change shape as needed and recognizing other cells for tissue and organ formation and immune response.
Explanation:The cell membrane plays a crucial role in maintaining homeostasis within a cell. Homeostasis refers to a state of balance within a living organism, which is essential for the survival and functionality of its cells. A significant function of a cell's
plasma membrane
is to define the cell and determine its interaction with its environment. This membrane is selectively permeable, allowing it to control what substances enter or exit the cell.
Growth and dynamic homeostasis
are maintained through the constant movement of molecules across this membrane. The cell membrane must also be flexible to allow cells to change shape as required by their environment. Lastly, the surface of the plasma membrane carries markers for cell recognition, which is essential for tissue and organ formation, and the distinction between 'self' and 'non-self' in the immune response.

The elastic rebound theory suggests which of the following?
Answer;
The elastic rebound theory suggest that; Most earthquakes are produced by the rapid release of energy stored in rock that has been subjected to great forces.
Explanation;
The elastic rebound theory was suggested by Henry Feilding Reid, who made observations and summarized that the earthquake occurs as a consequence of an elastic rebound of elastic strain energy that was previously stored in the rocks on either side of the fault.
The elastic-rebound theory explains how energy is produced when an earthquake occurs. According to this theory as adjoining plates on the Earth's surface move in opposite directions, then the rocks which span the opposing sides of the incipient fault are subjected to extreme shear stress.
The Elastic Rebound Theory explains the phenomenon of earthquakes caused by the sudden release of stored energy in strained rocks. When the stress exceeds the rock's strength, it fractures and rebounds, causing an earthquake.
Explanation:The Elastic Rebound Theory explains how energy is stored in rocks and is then released once the rocks crack or rupture, causing an earthquake. This theory is highly related to the study of tectonic plate movements and earthquakes. In a strained rock formation, when the stress exceeds the rock's strength, the rock fractures and subsequently rebounds, causing it to shake or vibrate leading to an earthquake. This displacement or movement of rocks is sudden and rapid, thus the term 'rebound'.

Which of the following best describes the solar radiation absorbed by and radiated from earth?
a. Most incoming solar energy is absorbed by the atmosphere.
b. Only a small fraction of energy radiating from Earth is from the atmosphere.
c. The Earth’s surface is responsible for a small fraction of heat radiation to space.
d. Earth’s surface absorbs little of the energy that strikes as solar radiation.
Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.
Explanation:
In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.

A fold where the youngest rock layer is in the center is called a(n) _____.
monocline
decline
syncline
anticline
A geological fold where the youngest rock layer is at the center is known as a syncline, a concave-upward fold with beds dipping towards the center.
A fold where the youngest rock layer is in the center is called a syncline. In geological terms, a syncline is a trough-like or concave-upward fold in which the beds dip towards the fold's central axis. By contrast, anticlines are the opposite, where the oldest rock layers are in the center and the rock layers dip away from the central axis. Synclines often appear as 'U' shaped formations in the Earth's surface and are indicators of the relative ages of strata within folded rock formations.
