Vertebrates have a bilateral symmetry due to which their entire body is divided into right and left halves while the invertebrates either have radial symmetry or the bilateral symmetry. Therefore, option D is correct.
The other basic differences between the vertebrates and the invertebrates are that vertebrates have a spinal cord and a backbone while invertebrates lack them, vertebrates have well developed brain, lungs or gills in respiratory system and closed circulatory system.
Answer:
because it doesn't release carbon emissions
Explanation:
hydrogen itself in a hydrogen powered car literally drains water out the exhaust while a gas or diesel engine releases carbon gas and pollution which harm the environment
Answer:
amoeba
Explanation:
Amoebas are organisms that are just basically jelly and a nucleus. There's an attached picture.
That "jelly" is called protoplasm; it's the fluid that makes up the amoeba's body.
Why not A: vacuoles are just protoplasm, no nucleus. they're not organisms.
Why not C: bacteria have no nucleus; they have a nucleoid region.
Why not D: a pseudopodium is an extension of an amoeba, kind of like a retractable arm.
Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.
Answer:
The relationship between both bacteria is Mutualism.
Explanation:
There are different ecological interactions between living organisms, depending on the benefits or harms that one or both species can receive as a result of their interaction. In this case, we talk about two bacteria that live on the surface of the Mixotricha paradoxa protist. These two bacteria have well-defined functions, <u>one is responsible for locomotion and the other for the generation of energy in the form of ATP</u>. In this interaction both organisms obtain benefits. When two organisms take mutual benefit from their interaction, it is called mutualism.
Other kinds of interactions are:
-Commensalism: An interaction that benefits an organism and the other organism is neither benefited nor harmed.
-Parasitism: One organism parasites the other to feed, causing damage to its host.
-Amensalism: One organism harms another without any benefit received.
