Explanation:

The  following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.

Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

Answer:

Oxbow lake is formed when a bend in a river is cut off to form a lake.

Explanation:

This statement is incorrect , as the shape of the oxbow lake is not like an ox , it is a horse-shoe shaped lake .

This statement is correct , as  An oxbow lake is a U-shaped lake that forms to create a free-standing body of water when a large meander of a river is cut off.

This statement is also wrong, as a river delta is specified by this statement.

This statement is also false, since the creation of a reservoir is established by this statement.

FORMATION OF OXBOW LAKE -:The neck of the meander gets narrower and narrower progressively. The curve gradually grows so close that the river slices through the neck of the meander to take a new, straighter path. Sediment locks the end of the old loop over time. This leaves a region of water that is different, called an oxbow lake.

Hence , the correct option is B.

Temperate deciduous forest

Explanation:

The temperate deciduous forest will have more organic matter concentration in it.

Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.

During cell reproduction, chromatin fibers coil up into structures called chromosomes. Therefore, the correct option is A.

Chromosomes are structures made up of DNA and proteins that are found in the nucleus of the cell. They contain genetic information That are responsible for the inherited characteristics of the organisms such as eye color, hair color, height etc.

Chromosomes play a crucial role in cell division, as they ensure the proper distribution of genetic material to the daughter cells.

During cell division, chromosomes are replicated and then separated into daughter cells, ensuring that each cell receives a complete set of chromosome.

The number and arrangement of a chromosome vary depending on the species, but all human cells except the sperm and egg cell contains 23 pairs of chromosomes. Hence, the correct option is A.

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.

Explanation:

Answer:

The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.[4] Gamma rays, X-rays, and high ultraviolet are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions.

Explanation:

Answer:Each color has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly chromatic light.

Answer:

A protein or ion has passed through the "pump" or carrier proteins and move within the cell.

Nvm short and sweet ;)

Further info..

To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.

Answer:

Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

The overall equation for photosynthesis using words is:

Carbon dioxide + water + sunlight energy → glucose + oxygen

Photosynthesis in plant chloroplasts and photosynthetic microorganisms is a complex metabolic process. Photosynthesis equation: [tex]CO_2 + H_2O + sunlight = glucose (C_6H_{12}O_6) + O_2.[/tex]

Photosynthesis converts carbon dioxide and water into glucose and oxygen. Special pigments like chlorophyll collect sunlight and transform it into chemical energy.

Photosynthesis underpins the food chain and sustains life on Earth. Primary producers, plants synthesise glucose that sustains all other organisms' growth and development. Photosynthesis provides oxygen for respiration and regulates carbon dioxide levels, preserving Earth's atmosphere.

The biogeochemical cycle of water, or the hydrological cycle describes the way that water (Hydrogen Dioxide or H 2 O) is circulated and recycled throughout Earth’s systems. All living organisms, without exception, need water to survive and grow, making it one of the most important substances on Earth.

hope that helps

Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.

A biogeochemical cycle is defined as the path by which a chemical substance cycles through the biotic and abiotic compartments of the Earth where the biotic factor is the biosphere and the abiotic factors are the atmosphere, hydrosphere and lithosphere.

Nutrients cycle occur through organic components as well as abiotic components. In biosphere the term bio refers to biotic components while 'geo' refers to abiotic components. Therefore, nutrient cycles in nature are called biogeochemical cycles.

Thus, Biogeochemical cycles represent the main system where the energy of the Sun is converted into the energy of chemical compounds by living beings and the products of their activity.

A non-polar fatty acids prevent cell membrane from dissolving in water. The correct option is A.

The cell membrane, also known as the plasma membrane, is uncovered in all cells and serves to separate the cell's interior from the outside environment.

The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.

These are glycerophospholipids, which are molecules made up of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon compound that serves as the membrane lipids' backbone.

As, these non-polar fatty acids are insoluble in water, so it protect the cell membrane from water. It actually prevent the cell membrane to get dissolve in the water.

Thus, the correct option is A.
