How did one-celled organisms form?
One-celled organisms are believed to have evolved from simpler molecules in the primitive Earth environment, eventually forming into structures capable of self-replication and metabolism. Over time, these structures evolved into more complex organisms through processes like natural selection and genetic mutations.
Do more-complex organisms always have more chromosomes than simpler organisms do.?
Chromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.
Do more-complex organisms always have more chromosome than simpler organisms do?
Yes
Do more complex organisms always have more chromosome than simpler organisms do?
Yes
What is deference between protozoans and bacteria?
Protozoans are eukaryotic, single-celled organisms with complex cellular structures and can be parasitic or free-living, while bacteria are prokaryotic, single-celled organisms that are much smaller in size compared to protozoans and have simpler cellular structures. Additionally, some bacteria can cause diseases in humans and other organisms, whereas protozoans are generally not known to cause diseases.
Are salmon eukaryote or prokaryote?
Salmon are eukaryotes. Eukaryotes are organisms whose cells contain a nucleus and other membrane-bound organelles, which is characteristic of all animals, including fish like salmon. In contrast, prokaryotes are simpler organisms, such as bacteria, that lack a nucleus.
Which is simpler a protist or a sponge?
Protist, which are mainly one-celled organisms.
What is a small single celled organisms that do not contain nuclei?
A small single-celled organism that does not contain nuclei is known as a prokaryote. Prokaryotes include bacteria and archaea, which are simpler in structure compared to eukaryotic cells that have a nucleus. These organisms have genetic material that is not enclosed within a membrane-bound nucleus.
Is mitochondria found in virsuses?
No, viruses do not have mitochondria. Viruses are simpler organisms that lack many cellular structures found in more complex organisms like mitochondria. They rely on host cells for energy production.
Which breaks down dead organisms into simpler forms?
Decomposers break down dead organisms into simpler forms through the process of decomposition. This includes fungi, bacteria, and other organisms that play a crucial role in returning nutrients back into the environment.
Is there a presence of complex organ systems in eubacteria and archaebacteria?
Eubacteria and archaebacteria are both prokaryotes and do not have complex organ systems like those found in eukaryotes. They have simpler cellular structures and lack membrane-bound organelles. These organisms rely on specialized structures within their cells to carry out essential functions.
Is chlorophyll always green?
no, because chorophyll is broken down into simpler coundpounds, so green color leaf color will gradually fade. (got it from website) no, because chorophyll is broken down into simpler coundpounds, so green color leaf colorwill gradually fade. (got it from website)
