Explanation:
Echolocation is one of the methods of orientation mainly used by the microchiropteran or insectivorous bats. While flying, these bats emit high frequency ultrasound. These sound pulses hit obstacles like rocks, trees, walls etc. and their echoes are heard by bats.
Bats are mammals that are capable of long flights. The uses pulses like the echolocation of ultrasound waves to navigate and catch prey in the darkness of night.
What is echolocation?
Echolocation has been defined as the emission of the sound waves by the mouth of the bats that get reflected back by the object which is useful in determining the distance, size, and shape of the object. These sound waves are ultrasound and cannot be heard by humans.
It is majorly used by dolphins and bats to navigate and communicate in the dark nights. It allows them to move freely without getting hit and to locate the food. The bats emit pulses and communication calls that are at a frequency of 34 kHz.
Therefore, bats use ultrasound-like echolocation to locate food and navigate.

All forms of pollution eventually taint water. Air pollution contaminates lakes and oceans. An underground stream, a river, and ultimately the ocean could all become contaminated due to land contamination.
What is the impact of pollution in the deep ocean region?The consequences of the toxins aren't usually obvious or simple to spot. Only in the cases of marine debris, man-made noise, and acidification by atmospheric CO2 can cause and effect be clearly shown.
The unfavorable climate makes it difficult to study the ocean floor. Instruments like sonar can be used to pollution study the seafloor in an indirect manner.
In contrast to mapping the land, the sea floor can't be directly measured from space using radar, since the water there absorbs the radio signals.
Therefore, With the aid of unique vehicles, it may be directly researched. To the ocean floor, certain vehicles transport scientists and their equipment.

Fertilizers can be distinguished from liming materials or other non-nutritional soil amendments. There are numerous fertilizer sources, both natural and man-made.
Fertilizers are plant food. Fertilizers replenish the essential minerals lost by crops in the soil. Crop yields and agricultural productivity would be significantly reduced if fertilizers were not used.
It provides nutrients to the plants throughout the growing season. The base fertilizer, along with presowing fertilization and top dressing, forms the fertilizer system used in crop rotation.

Activity Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. Part A What are the student’s observations and inferences before he starts his investigation?
Answer:
OFFICIAL ANSWER (do not copy verbatim):
The student has observed that artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he infers that compost will make his plants grow at a faster rate than they grow in plain soil.

The statement (C) is correct. The cellulose has more chemical bonds.
What do you mean by cellulose?Cellulose is an organic compound with the formula ₙ, a polysaccharide consisting of a linear chain of several hundred to many thousands of β linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes.
Moreover, cellulose, a tough, fibrous, and water-insoluble polysaccharide, plays an integral role in keeping the structure of plant cell walls stable. Cellulose chains are arranged in microfibrils or bundles of polysaccharide that are arranged in fibrils (bundles of microfibrils), which in turn make up the plant cell wall.
Hence, cellulose is an insoluble dietary fibre consisting of glucose polymers present in all cell walls of plants.
