How will distinguish between natural and artificial fibres by observing the smell produced when burnt?
its not biology it's chemistry
Answer:
Natural fiber smell like paper whereas artificial fiber smells like an acid.
Explanation:
We can distinguish between natural and artificial fibers by observing the smell produced when burnt because both produces different types of smell when burnt. When the artificial fibers are burn, it produces acid or chemical like odor and leaving a plastic like bead while on the other hand, when the natural fiber burn, it produces smell of burning paper or hair and leaving ash of soft and grey colour. Natural organic fibers burn rapidly with a yellow flame.

Why is it important for a cell to be able to turn a gene off?
Answer:
Gene regulation is an important part of normal development. Genes are turned on and off in different patterns during development to make a brain cell look and act different from a liver cell or a muscle cell, for example. Gene regulation also allows cells to react quickly to changes in their environments.

Explain what can increase the spread of cancer in the body.
Answer:
In metastasis, cancer cells break away from where they first formed (primary cancer), travel through the blood or lymph system, and form new tumors (metastatic tumors) in other parts of the body. The metastatic tumor is the same type of cancer as the primary tumor.

Which two elements have the most similar chemical properties?
aluminum and barium
nickel and phosphorus
chlorine and sulfur
sodium and potassium
Answer:
the answer is sodium and pottasium because their chemical properties are almost the same
Sodium and Potassium elements have the most similar chemical properties. So, the correct option is (D).
What is Periodic Table?The periodic table is also called the periodic table of the elements. It is described as an arrangement of chemical elements in rows and columns. It is widely used in chemistry, physics, and other sciences, and is commonly seen as a symbol of alchemy.
It consists of all discovered chemical elements in rows which is called periods and columns which is called groups according to increasing atomic number. There are 18 groups and 7 periods in the modern periodic table.
Element which belong to the same group have similar chemical properties like the elements in the first column of the periodic table which are lithium, sodium, potassium and so on have one electron in their outermost electron shell which means they share similar properties and behave similarly in chemical reactions.
Thus, Sodium and Potassium elements have the most similar chemical properties. So, the correct option is (D).

An underground water supply has a depth of 200 m of water. Water seeps in at the rate of 4 cm / year . Water is pumped out at the rate of 1m / year . How long will this water supply last? To find the net water loss from an underground water supply, subtract the amount that seeps into the water sup ply from the amount removed from the water supply. How long will the water supply last if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year ?
Answer:
208 years.
Explanation:
The water supply last for 208 years if the water seeps in at the rate of 4 cm / year and water is pumped out at the rate of 1m / year. The water supply last forever if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year because the same amount of water enters the underground which can be pumped from the soil. If more water is extracted from the soil as compared to it seeps, so with the passage of time water concentration in the soil decreases and in the last it disappeared.

process of how a seed grows into a plant
Answer: As it takes up more water, the seed expands and the seed coat cracks open. The embryo inside the seed is made up of a small shoot and a small root. The root is the first to emerge from the seed. As it grows, it anchors the plant to the ground, and begins absorbing water through the root.
