Answer:
storage of water and developmend of thorns
Explanation:
The cactus is the best example of a plant that has adapted very well to the desert.
The first adaptation has to do with water storage. Thanks to the long roots it has, it can absorve water from very deep areas. The water stored is stored in adapted vacuoles. The cells of the cactus are adapted to transpirate as little as possible, no to loose water in evatranspiration process.
The second adaptation has to do with it´s thorns. Big, rigid and pointy thorns are the perfect defense tolive in the dessert. Animals will tend to eat plants which will not harm them at all. This is why, thorns are a great protection against hungry eaters.

All foods contain chemical energy, but the amount of chemical energy is dependent of the type of food. The larger the compound, the more chemical bonds, and the greater amount of available chemical energy. We refer to the stored chemical energy in foods as calories. A calorie is the amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius. When we refer to the calories in food, we are really talking about kilocalories or 1000 calories.
Biology students used calorimetry to determine the energy provided by various food samples. They picked food samples of the same mass, 2 grams, and then set the food on fire using kitchen matches. The heat energy of the flaming food was used to heat 100 mL of water. Student results can be seen in the chart above.
What is one condition that may have reduced the accuracy of the temperatures recorded by the student groups?
A) type of foods used in the experiment
B) placement of thermometers in the cans
C) mass of food items used in experiment
D) amount of water measured into the cans
Answer: Option B
Explanation:
The placement of thermometers in the cans be a condition in which the accuracy can be reduced.
Calorie can be defined as the the energy required to raise the temperature of one gram by one degree Celsius.
The weight of the different foods is kept same and the initial temperature is also kept same.
The placement of thermometer should be accurate in order to get the accurate result free of error.

When animals on other farms respond when they hear rumors about animal farm Rebellion.
What is rebellion?
Each day, Snowball and Napoleon dispatched flocks of pigeons with the instructions to interact with the livestock on nearby farms, share the Rebellion's narrative with them, and teach them the tune to Beasts of England.
This notion was utilized by Presidents Truman, Eisenhower, Kennedy, and Johnson to support their military operations in Vietnam, Greece, and Turkey, nations they wanted to "rescue" from the rise of communism. The owners of the nearby farms in Animal Farm worry about a similar outbreak, which we might refer to as the "Snowball Effect."
Mr. Pilkington and Mr. Frederick propagated false information about Animal Farm in a similar manner to how the West attempted to discredit Russian communism.
Therefore, When animals on other farms respond when they hear rumors about animal farm Rebellion.

During digestion, what process or action breaks food down into smaller units that can be absorbed by the body?
Describe the effects that enzymes can have on substrates
Answer:
The effect of enzyme on substrate depends o the concentration of substrate and it affects the rate of reaction.
Explanation:
If the concentration of the substrate is low in a mixture, then substrates will bind to enzyme which will slow the rate of reaction. But if the concentration of the substrate is increased, then there will be more substrate for enzymes to work on and the rate of reaction will be increased.
There is a point upto which the enzymes will be involved in catalyzing action. When that threshold point is reached the increase in concentration of substrate will no longer increase the rate of reaction instead the rate if reaction will be uniform.

what would most likely happen if an error occurred when RNA was receiving coding information?
Answer:
This RNA would form proteins with incorrect coding and would result in a genetic mutation.
Explanation:
Mutations can be defined as changes that occur in the genetic material of living organisms. These changes are an important source of genetic variability and are often responsible for the emergence of new species. Changes in genetic material are extremely important, it is the nucleic acids that carry the information needed for protein synthesis, when one of these nucleic acids (RNA or DNA) is incorrectly coded, the result will be an incorrect protein that will form a characteristic that wasn't being expected in the body .
Which of the following statements about olfactory receptors is false?
They are bulb-like structures at the tip of the frontal lobe where the olfactory nerves begin.
They are cells.
They are located in a mucous membrane at the top of the nose. \
They have small, hair-like extensions.
The false statement about the olfactory receptors is they are bulb-like structures at the tip of the frontal lobe where the olfactory nerves begin.
Further Explanation:
Receptors are the protein molecules present on the cell surface which binds to the ligand and cause response in the immune system. Receptors have the primary role in controlling membrane channels, cell division, and cell growth.
Olfactory receptors are an odour or smell molecules which are mainly found in arthropods, animals and terrestrial vertebrates. These receptors are present in the nasal cavity forming nasal epithelium. It consists of cilia which are covered by the mucus of the nasal cavity. Cilia facilitate the response to olfactory receptors.
Olfactory receptors are not bulb-like structure. It has an olfactory bulb that lies on the ventral aspect of the frontal lobes. Olfactory receptors are the cells located in a mucous membrane at the top of the nose. They have small hair-like extensions which are particularly known as cilia. These cilia contain active sites for the process of olfactory transduction.

Describe the major differences in acute versus passive range of motion (rom) when distinguishing between an articular and nonarticular joint issue.
The major difference between an acute and passive range of motion based on the articular and non-articular problem is that:
In articular problems, active and passive range of motion is restricted. In non-articular problem, only articular range of motion is restricted.
Further Explanation:
The joints are formed by the articulation of the two or more bones and muscles. These joints are the characteristics of the range of motion. The articulation of the bone type determines the type of movement. The articular structure is consisting of synovial fluid, synovium, intra-articular ligaments, articular cartilage, and joint capsule. Bone, muscle, nerve, tendons, ligaments are non-articular structure.
Articular problems are described by swelling, diffuse pain and a very limited range of motion on passive and active movement. Non-articular problems are more painful in the active range of motion, whereas no pain in passive motion.
To examine the active range of motion, a doctor asked a client to move their body. There is no external force or pressure is applied to the body, whereas in a passive range of motion, an external force is applied to move the body. In the case of a particular problem, there is a restriction in the movement of joints.

how are hydrogen bonds different from covalent bonds?
A.) They are organic.
B.) Hydrogen bongs are weaker bonds that form from molecules that have a slight positive charge on one side and a slight negative charge on the other.
C.) They have valence electrons.
D.) The resulting compounds contain carbon.
Hydrogen bongs are weaker bonds that form from molecules that have a slight positive charge on one side and a slight negative charge on the other.
Molecules with a tiny positive charge on one side and a slight negative charge on the other create weaker bonds called hydrogen bongs. Thus, option B is correct.
What is a hydrogen bond?Chemical bonds that are present in covalent compounds include covalent and hydrogen bonds.
The sharing of electrons between atoms results in the formation of a covalent bond. The attraction between two atoms of two distinct molecules results in the formation of a hydrogen bond.
When a hydrogen is covalently bound to one electronegative atom, an attraction called a hydrogen bond is created.
Because a hydrogen is an attraction rather than a true bond, it differs from a covalent bond. Because the positive charge of the hydrogen is drawn to the negative charge of another atom, there is an attraction.
Therefore, hydrogen bonds different from covalent bonds.
