What activity asks? Activity 8.10 asks us ti correlate the distance-time graph of objects with different speeds. Answer--Here we will plot distance on x-axis and time in minutes on the y-axis. Now we need to plot the given distance and time. Once we draw the line, we will get requested graph. After this, we can interpret it easily. [I don't no how to transfer on this app for answer (photo) si u make the graph okkk.... sorry fir the graph] Interpretation: 1)The graph is not straight line for both. It indicates that the speed of each person changes with time. If they had the uniform speed we would have got a straight line. 2) IMPORTANT:Here we see two different graphs for the same distance. It indicates that both people are having different speeds. The area covered in each unit of time indicates the distance. Here it is more for Firoz till 8:20. After 8:20 the total sum of the area represents total distance. So,both, Firoz and Sania will have an equal area on the graph. Interpretation: From a graph we can know if the motion is uniform if the line is straight; the area below the slope represents the distance.

Activity 8.9 asks us to plot a distance-time graph. We should take two axis on the graph paper. One a us represent distance while the other represents time. At 8:00 Distance=0km 11:15 distance=120km at 13:15 = 180 km Fir more precision we can add 15 minute time gap at station B and C

Cell is called the fundamental unit of life. A cell is capable of independent existence and can carry out all the functions which are necessary for a living being. A cell carries out nutrition, respiration, excretion, transportation and reproduction; the way an individual organism does. A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms.

Sap is a fluid transported in xylem cells (vessel elements or tracheids) or phloem sieve tube elements of a plant. These cells transport water and nutrients throughout the plant. Xylem sap consists primarily of water, along with hormones, minerals, and nutrients. Phloem sap consists primarily of water, in addition to sugar, hormones, and mineral elements dissolved within it. Tree sap flows through sapwood, which produces carbon dioxide.

Euglena is a protist that can both eat food and can photosynthesize. When acting as a heterotroph, the Euglena surrounds a particle of food and consumes it by phagocytosis. When acting as an autotroph, the Euglena utilizes chloroplasts to produce sugars by photosynthesis thats why it is said to be a plant animal.

Deuterium is a hydrogen isotope consisting of one proton, one neutron and one electron. Tritium is a hydrogen isotope consisting of one proton, two neutrons and one electron. It is radioactive, with a half-life of 12.32 years. The main difference between protium, deuterium, and tritium is that protium has no neutrons in its nuclei, whereas deuterium is composed of one neutron and tritium is composed of two neutrons. Protium is an isotope of hydrogen that is composed of one proton and one electron.
