Both osmosis and diffusion require energy and are considered active transport
True or False?!
Explanation:
Diffusion can be defined as the movement of the particles from a higher amount to the lower amount. it is usually used for gaseous particles.
Osmosis can be defined as the movement of the solvent particles from an area where its amount is high or more to an area where its amount is low or less through the semi permeable membrane.
These two processes does not requires energy and is not an active process.

a. True
b. False
The statement is true. Disinfectants and antiseptics are both types of antimicrobial chemicals. Disinfectants are used for inanimate objects while antiseptics are for living tissues.
Explanation:This statement is indeed true. Both disinfectants and antiseptics are antimicrobial chemicals. Disinfectants are substances that are applied to non-living objects to destroy microorganisms. For example, you might use a disinfectant to clean a bathroom. On the other hand, antiseptics are applied to living tissues to reduce the possibility of infection, sepsis, or putrefaction. For instance, a doctor may use an antiseptic on your skin before making an incision.

Rice is a procedure for treating minor strains and sprains. what does it stand for?
"The acronym RICE stands for Rest, Ice, Compression, and Elevation. It is a common treatment for minor strains and sprains.
To elaborate on the RICE method:
- Rest: The first step is to rest the injured area to prevent further damage and to allow the body to begin the healing process.
- Ice: Applying ice to the injured area helps reduce swelling and pain. Ice should be applied for 20 minutes every 2 to 3 hours during the first 48 hours after the injury.
- Compression: Wrapping the injured area with an elastic bandage can help minimize swelling and provide support. However, the bandage should not be too tight as to cut off circulation.
- Elevation: Elevating the injured area above the level of the heart also helps reduce swelling by decreasing blood flow to the area.
The RICE method is most effective when it is started soon after the injury occurs and continued for at least 48 hours. It is important to note that while RICE can be very effective for minor injuries, more serious strains and sprains may require medical attention."

Describe the stages of photosynthesis. Use the terms thylakoid, light-dependent reactions and light-independent reactions.
Photosynthesis in plants occurs in two stages. These stages are known as the light-dependent reactions and the Calvin Cycle.
The first stage of photosynthesis is the light dependent reactions. These reactions take place on the thylakoid membrane inside the chloroplast. During this stage light energy is converted to ATP (chemical energy) and NADPH (reducing power).
The second stage of photosynthesis is the Calvin Cycle. These reactions occur in the stroma of the chloroplast. Energy from ATP and electrons from NADPH are used to convert carbon dioxide into glucose and other products.
Photosynthesis comprises of two stages: the light-dependent reactions, which occur in the thylakoid membrane and convert light energy into chemical energy, ATP and NADPH, and the light-independent reactions, or Calvin Cycle, which happen in the stroma and utilise the ATP and NADPH to convert carbon dioxide into sugars.
Explanation:Photosynthesis consists of two stages: the light-dependent reactions and the light-independent reactions, or Calvin cycle. Initially, the light-dependent reactions occur in the thylakoid membrane where light energy is captured by pigments (like chlorophyll) and converted into chemical energy, ATP and NADPH. These reactions also involve the splitting of water molecules and the releasing of oxygen. The energy-carrying molecules ATP and NADPH are then passed on to the second stage of the process.
The light-independent reactions, otherwise known as the Calvin cycle, take place in the chloroplast stroma. Here, ATP and NADPH are used to transform carbon dioxide into sugar (carbohydrates) through a series of complex enzymatic reactions. Although they were named light-independent reactions because they do not use light energy directly, they rely on the ATP and NADPH produced by the light-dependent reactions.

How is breathing related to cell respiration? (Hint: Think about both the reactants and the products of cellular respiration)
Answer:
We breathe oxygen that is captured through cellular respiration.
Explanation:
Cellular respiration is the chemical process carried out by living beings and takes place inside cells. It is necessary to maintain the functioning of our body. For cellular respiration to happen efficiently, in addition to the absorption of oxygen (which is essential for our breathing), the body's nutritional needs must be met. That is, living beings need to ingest carbohydrates, lipids and proteins. However, as these molecules are large, the organism needs to break them down so that they can be used as an energy source. After ingestion, simple carbohydrates, such as glucose, fatty acids and amino acids, remain. Cellular respiration takes place at this stage.
Most used by living beings, aerobic respiration uses glucose as its main source of energy. Its function is to start from the molecules, obtained by the producing organisms, in the process of photosynthesis and by consumers' food. Aerobic respiration is represented by the following equation: C6H12O6 + 6 O2 - 6 CO2 + 6 H2O + Energy
In this equation, it is possible to identify that the glucose molecule (C6H12O6) is divided, so that it can originate the simplest substances (CO2 and H2O). This mechanism occurs within the mitochondria, a cytoplasmic organelle that acts as a power plant. With this, several reactions with the participation of enzymes and coezimas are carried out within the aerobic respiration, which favors the constant oxidation of glucose. In this way, this way of obtaining energy generates thirty-six moles of ATP from one mole of glucose. Aerobic respiration is divided into three stages: glycolysis, the Krebs cycle and oxidative phosphorylation (respiratory chain).
Breathing is related to cell respiration as oxygen is used in cellular respiration and carbon dioxide is exhaled during breathing.
Breathing is related to cell respiration in several ways. In cellular respiration, oxygen is used as a reactant to break down glucose and produce ATP, which is the energy currency of cells.
Carbon dioxide is a waste product of this process and is exhaled during breathing.
The respiratory system, which includes the lungs, muscles, and passageways, helps to transport oxygen from the air into the body and remove carbon dioxide.

Is a crocodile a carnivore herbivore or omnivore?
Crocodiles are carnivorous animals that feed on many vertebrates such as fish, reptiles, birds and mammals, and occasionally invertebrates such as molluscs and crustaceans, depending on the species and age.
What are Carnivorous?A carnivore is defined as an organism that eats mostly meat, or the flesh of animals. Sometimes carnivores are called predators while the organisms that prey on carnivores are called prey. Carnivores are a major part of the food web which is the details of which organisms eat which other organisms in the wild.
These are described as animals that eat other animals. The word is derived from the Latin word and means "flesh-eater." Wild cats, such as lions, crocodiles and tigers, are examples of vertebrate carnivores, as are snakes and sharks, while invertebrate carnivores include sea stars, spiders, and ladybugs.
Thus, Crocodiles are carnivorous animals that feed on many vertebrates such as fish, reptiles, birds and mammals, and occasionally invertebrates such as molluscs and crustaceans, depending on the species and age.

Daphnia are freshwater organisms sometimes referred to as “water fleas.” Design an experiment that
could be used to test the effects of temperature on the size of a daphnia population. In your
experimental design, be sure to:
• state a hypothesis to be tested
• describe how the control group will be treated differently from the experimental group
• identify the independent variable in the experiment
• identify the type of data that will be collected
Answer:
Experiment to test the effect of temperature on the size of a daphnia population:
1. The hypothesis to be tested is: "Cooler temperature will reduce the size of the population due to a decrease in the reproduction rate while the hotter temperature will increase the size of the population due to an increase in the reproduction rate.
2. In all groups, daphnia will be counted weekly at the same time. The amount of water and nutrients supplies will be the same between groups. The only thing that will change is the temperature. For example:
Control group will be at 20 Celcius degrees, the cooler group will be at ten Celcius degrees, and the hotter group will be at 30 Celcius degrees.
3. The independent variable is the temperature.
4. The dependent variable (data that will be collected) is the size of the population.
Explanation:
Daphnias are microscopic crustaceans, which are called water fleas because of their saltatory behavior like fleas. Their life span and reproduction can be affected by different factors, including the abundance of predators, food, and temperature. They alternate their reproduction strategy during their life; they can reproduce asexually and sexually. Lower temperatures (cooler) decrease their metabolic and reproduction rate while higher temperature (hotter) increase their metabolic and reproduction rate. Because they can reproduce more times during their life span and the reproduction rate is higher in higher temperatures, I expect that temperature will affect the size of the population of Daphnia.

During the cold winter months, the surface of a lake becomes hard ice. This is due to which change of state?
Condensation
Evaporation
Melting
Freezing
Answer:
Freezing
Explanation:
During cold winter months, the water on the surface of lakes/water bodies changes its state from liquid to solid state (ice) and the process is known as freezing. This phenomenon helps the flora and fauna living under such water bodies survive even in extremely cold weather. The ice being less dense than water floats on the surface of lake and acts as a shield. This shield of ice acts as an insulator and restricts the outside cold waves from entering the water beneath the ice cover and maintains optimum temperature inside. Hence due to the change of state of water, the flora and fauna is able to survive even in harsh winter season.
