Have you ever sat around a campfire or watched flames flicker in a fireplace? The burning of wood is a chemical reaction. A chemical reaction always involves changes in chemical bonds that join atoms in compounds. The elements or compounds that enter into a chemical reaction are called reactants. The elements or molecules produced by a chemical reaction are called products. As wood burns, molecules of cellulose are broken down and combine with oxygen to form carbon dioxide and water vapor, and energy is released. What are the reactants when wood burns? What are the products when wood burns?
Answer:
The correct answer is -
Reactants - oxygen and cellulose.
Products - carbon dioxide and water (carbon residues sometimes)
Explanation:
Burning wood is a chemical reaction that involves a reaction between reactants and produces products with energy. In this chemical reaction, the reactants that take part are oxygen present in the atmosphere and cellulose (wood made up of cellulose).
In this reaction a lot of energy or heat loss takes place and at the end of the reaction carbon dioxide and water produces. however, sometimes other substances also present.

Which statement accurately describes a light-year?
It is the shape of a galaxy.
It is the distance that light travels in a year.
It is a yearly measurement of light given off by stars.
It is the amount of time it takes light to travel one million kilometers.
The statement accurately describes a light-year is it is the distance that light travels in a year. Therefore, option (B) is correct.
What do you mean by light year?A light-year, also spelled light year, is a significant length measure that is used to express astronomical distances. It is around 9.46 trillion kilometers, or 5.88 trillion miles, in length.
The distance that light travels in a light-year is one year. At 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year, light travels through interstellar space.
The distance that light travels in a year is called a light year (365 days). Because "year" is right there in the name, it is frequently used incorrectly as a measure of time.

What is volume of a substance?Volume of a substance is defined as the space it occupies. Length, width and height of a substance are taken into consideration for measuring volume. Thus, volume is a three dimensional quantity.
It is the product of length, width and height of a substance. Volume is expressed as unit per cube. The SI unit for volume is m3.
It is possible to calculate the density of matter, if the volume and mass of the substance is known.
Here, to find out volume of a computer; the product of length (46cm), width (20 cm) and height (48 cm) is taken.
Therefore, the answer is 44160 cm3.

(c) Many bacterial diseases can no longer be treated with antibiotics. Outline how
antibiotic-resistant strains of bacteria can develop.
Antibiotics kill or inhibit the growth of susceptible bacteria. Sometimes one of the bacteria survives because it has the ability to neutralize or escape the effect of the antibiotic; that one bacterium can then multiply and replace all the bacteria that were killed off. Exposure to antibiotics therefore provides selective pressure, which makes the surviving bacteria more likely to be resistant.
which cell organelles are known as secretary vesicles
Answer:
the membrane
Explanation:
Secretory vesicles are tiny little packages in which certain cell secretions can be transported. The vesicles are membrane bound and produced by the golgi apparatus or endoplasmic reticulum. Most vesicles will have specialized functions and specific materials which they transport. In addition to transportation, secretory vesicles can store or digest certain secreted molecules. Synaptic vesicles store neurotransmitters, hormones are stored in secretory vesicles for release into the blood stream, and enzymes are also stored in secretory vesicles to be used when needed to make cell walls in certain plants, fungi, and bacteria. The release of the substances inside of the secretory vesicle can be stimulated by a neural or hormonal signal. The membrane of the vesicle can then fuse with the membrane of the target cell and essentially spill its contents. The vesicle then adds its membrane to that of the target cell. This is typically temporary until another vesicle is created when certain components are then removed from the cell.
