The question is incomplete. The rest of the question is : Which of these is not supported by the endosymbiosis theory concerning organelles?
A) contain DNA.
B) contain ribosomes.
C) are capable of living independently.
D) are surrounded by a double membrane.
Answer:
Option C) are capable of living independently is not supported by the endosymbiosis theory concerning organelles
Explanation:
The endosymbiosis theory proves that chloroplasts and mitochondria were prokaryotic cells before due to many reasons. Some of which are:
- These organelles have their own separate DNA.
- The separate DNA present in them is capable of making their own proteins.
- They are membrane- bound organelles.
However, these organelles can now not live separately outside of the cell. This might be because of the evolutionary changes which occurred in these cells during the long period of time.
DNA: double-stranded helix held by complementary base pairs. Which the DNA carries the genetic info for making the proteins. The four bases A, T, C and G make up the genetic code. The base succession determines amino acid excerpt in the protein.
in which I got some information about this from edubuzz or something like that but I can't put a correct complete link of website
Their sequence was:
1). Mercury
(one astronaut in the capsule, in Earth orbit)
2). Gemini
(two astronauts in the capsule, in Earth orbit)
3). Apollo
(three astronauts in the capsule, in Earth orbit, then to the Moon)
4). Space Shuttle
(crew of six, in Earth orbit; carried other satellites and put them into orbit;
carried the Hubble Space Telescope and put it into orbit;
carried materials and began construction of the International Space Station;
ferried astronauts and supplies to and from the ISS.)
Because by practicing, they control there breathe and also increase the volume of the lungs ! so , it is just practice, we can also have that type of lung by regular efforts !
Answer:
I believe your answer is B
Explanation:
An organ is a self-contained group of tissues that performs a specific function in the body. The heart, liver, and stomach are examples of organs in humans. ... Organs are found in most animals and plants.
An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ does a particular job in the body, and is made up of distinct tissues.
