Answer:
The correct answer is- Lophotrichous
Explanation:
There are four types of bacteria based on the presence and distribution of flagella on them. The bacteria which have only one flagellum at one pole that bacteria is called monotrichous.
The bacteria which have single flagella at both sides are called amphitrichous. Bacteria that have numerous flagella distributed evenly on their body surface are called Peritrichous.
The bacteria which have a tuft of flagella attached on one side or pole are called lophotrichous. Therefore the correct answer is lophotrichous.
Answer: The Cell structure.
Explanation: Most Archaeas don't have membrane-bound organelles, they are mostly unicellular prokaryotic organisms.
Archaea are found living alongside bacteria in many environments. Recently Archaea belongs to Crenarchaeota have been implicated in nitrogen cycling in the soil.
Fungi are eukaryotic multicellular organisms and they have membrane-bound organelles. they are hence more closely related to plants and animals than to bacteria or archaea. Like eukaryotes, Fungi has nuclei with chromosomes that contain DNA. They possess membrane-bound organelles such as mitochondria. Fungi are heterotrophs, and they are saprophytic, they feed on decaying matter. some fungi occur as unicellular organisms, they are generally referred to as yeasts.
The question above is incomplete, the complete version of the question is given below:
In the early days of germ theory, contagious diseases were thought to be caused by fungi or bacteria. In the 1890s, Dmitri Ivanovski filtered extracts from diseased tobacco plants and discovered that the disease could be transmitted to new plants through the filtrate. He concluded that the disease was caused by particles smaller than bacteria: the tobacco mosaic virus.
Which best explains how Ivanovski’s work led to a change in the germ theory?
A. He tried to promote his hypothesis as a law.
B. He used a new experimental method to test his hypothesis.
C. He used a more powerful bacterial strain than other scientists had.
D. He obtained results that confirmed what other scientists were thinking.
ANSWER
The correct option is B.
The germ theory of diseases states that diseases are caused by microbes. Prior to 1890s, scientists believed that communicable diseases are caused by microorganisms such as bacteria and fungi; viruses were not known during that time. The work of Dmitri Ivanovski on tobacco plant was the one responsible for the discovery of the existence of viruses. Dmitri Ivanovski was able to arrive at the results he obtained because he used a new experimental method to test his hypothesis.
The amplitude of the sound wave determines the range of variation of pressure, compression, or displacement. Amplitude is the volume of the sound in sound waves. The higher the Amplitude, the louder is the sound. Sound waves are pressure or compression waves in the material through which the sound is traveling. So I'd say D.
Water molecules will pass through the cell membrane into the cytoplasm of the cell causing it to swell and become turgid until it get to the elastic limit where the cell splits or burst
