Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).
Thus, Nonflammable materials are those that do not readily ignite and do not burn even when exposed to high temperatures or flames.
Combustion Behaviour: During a fire, when wood is exposed to heat and oxygen, a combustion process takes place, releasing heat, light, and numerous combustion byproducts like carbon dioxide and water vapour.
The fire is maintained and can spread as a result of this procedure. Even when exposed to high heat or flames, nonflammable materials do not burn and do not support a fire.
Thus, Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).

I need a small text (about 50 words) for the human brain.
Answer:
The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.The largest part of the human brain is the cerebrum, which is divided into two hemispheres, according to the Mayfield Clinic. Underneath lies the brainstem, and behind that sits the cerebellum. The outermost layer of the cerebrum is the cerebral cortex, which consists of four lobes: the frontal, parietal, temporal and occipital. [Nervous System: Facts, Functions & Diseases]
Like all vertebrate brains, the human brain develops from three sections known as the forebrain, midbrain and hindbrain. Each of these contains fluid-filled cavities called ventricles. The forebrain develops into the cerebrum and underlying structures; the midbrain becomes part of the brainstem; and the hindbrain gives rise to regions of the brainstem and the cerebellum.

Answer: Hewo, there! your answer is below
Mass
Mass is a measure of how much matter an object contains.
Explanation:
Mass is a property that an object has no matter where it is located. Weight, on the other hand, depends on the force of gravity acting on that object.

Texto donde se desarrolle la definicion de seleccion natural. Además, empleem los siguientes terminos: Variabilidad, mecanismo selectivo y Darwin.
Answer:
la selección natural es el mecanismo principal por el cual la evolución ocurre
Explanation:
Charles Darwin fue un naturalista inglés que propuso la teoría de la evolución o 'descendencia con modificación' mediante el mecanismo de selección natural. Acorde a esta teoría, la selección natural se define como el mecanismo selectivo de reproducción diferencial de los individuos mejor adaptados a su ambiente. La variabilidad es el la materia prima sobre la cual la selección natural actúa, seleccionado aquellos individuos que presentan combinaciones fenotípicas y genotípicas más adaptadas para sobrevivir en un ambiente en particular. Los individuos de una población que son 'superiores adaptativamente' poseen más chances de sobrevivir y reproducirse, y por lo tanto tienen también más probabilidades de transmitir sus genes a la siguiente generación.

When a pelican gets hot, it opens its bill and flutters the sides of its pouch. This causes water to evaporate, which cools the pelican. What type of adaptation is the movement of the pelican’s pouch?
behavioral adaptation
life-cycle adaptation
physical adaptation
reproductive adaptation
Answer:
Behavioral adaptation
Explanation:
life-cycle adaptation would be like a tadpole growing legs.
physical adaptation would be a change in the animals body like wings for a bat.
reproductive would be beneficial for making offspring like a peacocks bright feathers that attract mates.
Behavioral adaptations are responses to external stimulus like heat.
So behavioral is the best option.

The flooding of fields in winter can affect aquifers without having long term impacts on the height of the water table. Which statements explain why this is possible?
Select the TWO correct answers.
A. In winter, using groundwater to flood fields causes the water table to drop because water is withdrawn from the aquifer.
B. In winter, removing water from the aquifer causes the water table to rise because water covers the areas where rice is grown.
In spring, changes in the level of the river cause the water table to rise because water flows from the river into the aquifer.
C. In spring, removing water from the aquifer causes the water table to drop because water flows from the aquifer to the river.
D. In summer, changes in the level of the river cause the water table to rise because water flows from the river to the aquifer.
The flooding of fields in winter has no long-term effect on the height of the water table because removing water from the underground water - the aquifer causes water to drop and summer melts water into the water table.
Aquifers, Water Tables, Summer, and WinterDuring winter, the flooding of the field traps water from going back into the aquifers and the use of water from them causes the water level to drop.
Due to the melting of snow in summer, the water levels are normalized. Therefore, the correct answers are C and D.

Which structure separates an animal cell from its surrounding environment? (1 point) 1 Golgi apparatus 2 plasma membrane 3 nuclear membrane 4 central vacuole
Answer:
2) plasma membrane
Explanation:
The structure that separates the cell from its surrounding is plasma membrane, the correct option is 2.
What is plasma membrane?The plasma membrane, also renowned as the cell membrane, is the membrane located outside all cells that distinguishes the cell's interior from its surroundings.
A cell wall is attached to the plasma membrane on the outer of the plasma membrane of bacterial and plant cells.
The semi-fluid living matter in the cell is called protoplasm or in other words simply plasm. This living matter, or one can say plasm, is contained within the plasma membrane, a biological membrane.
Lipids which are phospholipids and cholesterol, proteins, and carbohydrate groups attached to some of the lipids as well as proteins are the primary components of the plasma membrane.
A phospholipid is a sort of lipid that is created by glycerol, two fatty acid tails, and a phosphate-linked head group.
Thus, the correct option is 2.

If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), later analysis will show that all of the following molecules produced by the algae contain 18O except If photosynthesizing green algae are provided with CO2 containing heavy oxygen (18O), later analysis will show that all of the following molecules produced by the algae contain 18O except ribulose bisphosphate (RuBP). O2. 3-phosphoglycerate. glucose. glyceraldehyde 3-phosphate (G3P).
Answer:
Option B, O2
Explanation:
It is because the oxygen released during the process of photosynthesis comes from the water absorbed by the roots and not by the CO2containing heavy oxygen (18O). In fact oxygen from CO2 containing heavy oxygen (18O) is used in making sugar which is then stored for energy.
Hence, option B is correct
