The speed of an object is denoted by a distance time graph.
Explanation:
The speed of an object is calculated on the basis of distance travelled in per unit of time. The distance and time graph's gradient shows the speed of the object. Distance is referred to as measure of the path between two points. Displacement is the vector quantity that measures distance with a line that is straight in nature.
The velocity of the object is represented as the speed by which the object moves in a particular direction. The acceleration of the object can be measured by a velocity - time graph.
Answer:
A climax community develops
The glacier retreated, leaving barren only rock
Lichen and other pioneer species grown on the rocks
Rock is broken down and converted into soil
Grasses and flowering plants grow in the soil
Shrubs and small trees grow in the soil
Small pine trees grow in the soil
Explanation:
hope its correct can i get brainliest i spend a lot of time on it
Answer:
These strands are clones, however, due to their low genetic variability, the population becomes susceptible to diseases taking place in plants. Pando comprises grove of about 47000 trunks, these all are genetically similar that develops from a solitary underground species, Quaking aspen tree. Pando is an extremely large clone.
However, for the past some years, scientists are worried about Pando's health. For the past thousands of years, Pando was living in fine tune with the native wildlife population, but for the past some years, a shift in balance is noticed. As in the absence of the development of novel stems, nothing will be able to substitute the natural withering of the older ones, if this goes on, the death of Pando will take place.
Answer: for cell membranes it would be phospholipids, proteins, carbohydrates and cholesterol.
Explanation:
The levels of structure which are broken when a protein is denatured are the secondary, tertiary, and quaternary structure.
Secondary structure: This level of structure describes the local folding pattern of the polypeptide backbone and is stabilized by hydrogen bonds between N-H and C=O groups.
Tetiary structure describes how regions of secondary structure fold together – that is, the 3D arrangement of a polypeptide chain, including a helices, b sheets, and any other loops and folds. Tertiary structure results from interactions between side chains, or between side chains and the polypeptide backbone, which are often distant in sequence.
Quaternary structure: Some proteins are composed of more than one polypeptide chain. In such proteins, quaternary structure refers to the number and arrangement of the individual polypeptide chains.
