2. Amebas are single-celled organisms that need to obtain food in order to(1) release oxygen into the air (3)(2) protect themselves from other living things(3) get the energy they need to carry out life functions(4) remove harmful chemicals from the environment 相关知识点: 试题来源:...
Now, minerals are not alive of course, so this is not evolution in quite the same sense you'd have in living organisms, but there do appear to be some parallels. Living organisms not only adapt to their environment, but also affect it, change the environment within which other organisms ...
“如果没有细菌”(事实上存在细菌)Jenny: Oh, and bacteria are also useful at the other end of the food production process.They have an important role dealing with your waste and that of other organisms.Josh: Euw! You mean what goes down the toilet?Jenny: Yes Bacteria break down this ...
Bacteria are single-celled organisms that are pretty much everywhere: in the ground, in the ocean, on your hands and in your gut. While some are harmful, most are not — and some are even beneficial to human health. In many cases, humans live in symbiosis with bacteria, maintaining a mu...
Viruses are tiny particles—much smaller than bacteria, which are microscopic single-celled organisms. A single virus is called a virion, and it’s comprised of RNA or DNA genome enclosed in a protein covering called a capsid. Some viruses are also enclosed in an outer lipid membrane, called...
Life slowly moves from single-celled organisms to the simplest multicellular organisms. Multicellular organisms range from simple aggregated multicellular organisms to systemic to organised organisms. With the advent of sexual reproduction, the evolution of organisms has become more rapid and complex. Why ...
These are organisms that lack some of the cell organelles such as the nucleus, mitochondria, and Golgi apparatus. Classes of kingdom monera include: Archaebacteria. Eubacteria. Cyanobacteria.Answer and Explanation: The following are the characteristics of cyanobacteria: They are prokaryotes. ...
Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles. Eukaryotes are single or multicellular organisms with distinctive and enclosed nucleus, and cell organelles.Answer and Explanation: Archaea are primitive microorganisms that are structurally similar to bacteria but are...
To answer the question "Multicellular decomposers are," we will analyze the options provided: saprophytic plants, saprophytic bacteria, fungi, or monerans.1. Understanding Decomposers: Decomposers are organisms that break down
In the study, the scientists examined molecular fossils from core samples taken during ocean drilling projects. The fossil remains are single lipid (water-insoluble) molecules created by archaea, which are single-celled organisms similar to bacteria. The archaea adjust the composition of their outer ...
