Answer:
Scientists first discovered chromosomes in the nineteenth century, when they were gazing at cells through light microscopes. But how did they figure out what chromosomes do? And how did they link chromosomes — and the specific genes within them — to the concept of inheritance? After a long period of observational studies through microscopes, several experiments with fruit flies provided the first evidence.

How can water-holding capacity of soil be improved?
O Increasing irrigation on the soil
O Reducing drainage on soil surface
O Tilling soil
Adding compost or organic matter to the soil
Answer:
Soil organic matter (SOM) is another factor that can help increase water holding capacity. Soil organic matter has a natural magnetism to water. If the farm increases the percentage of soil organic matter, the soil water holding capacity will increase. SOM is decayed material that originated from a living organism.

If we heat a substance or chemical in a test tube, we should hold it away from people because may be it can explode and the chemical split on the body that cause serious problems in people. We have to handle laboratory procedures very carefully because the chemicals are not good for health and can cause serious diseases in humans and can damaged the skin very badly so we can conclude that the open end of the test tube should be placed away from the people.

explain how capillaries are adapted for their functions
Capillaries have walls only one endothelial cell thick, meaning their walls are very thin. This makes them well adapted for gas exchange, as substances only have to diffuse over a short distance. Additionally, there are many capillaries within a capillary bed. This also increases the surface area available for gas exchange, making exchange more efficient.

In the metric system, all are units 1000 times larger than a base unit. The correct option is c.
What is a metric system?The metric system is a measurement system that employs the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass).
The meter, gram, and liter are the three most common base units in the metric system.
This name is derived from the Greek word metron, which means "measure."
The physical standard for the meter was to be built to equal one ten-millionth of the distance between the North Pole and the Equator along the meridian running between Dunkirk, France, and Barcelona, Spain.
The kilogram, kilometer, and kilocalorie all share the property of being 1000 times larger than a base unit in the metric system.
Thus, the correct option is c.
