The DNA in the nucleus and mitochondria are the same.
This is not exactly true, although they are similar. This is not a correct option.
The following three are correct options:
Mitochondria and chloroplasts grow independently from the cell.
This is true, and supports the idea that they previously existed as their own organisms.
Prokaryotic cells, mitochondria, and chloroplasts are all the same size.
All three organisms/organelles are roughly the same size, which supports the idea that chloroplasts and mitochondria are descendants or prokaryotes.
Mitochondria and chloroplasts contain their own ribosomes.This is true as well.
Answer:
The cytoskeleton is a network of fibers that forms the "infrastructure" of eukaryotic cells, prokaryotic cells, and archaea. In eukaryotic cells, these fibers consist of a complex network of protein filaments and motor proteins that help move cells and stabilize the cell.
Explanation:
Function:
It helps the cell maintain its shape and provides support to the cell.
Various cellular organelles are held in place by the cytoskeleton.
It helps in the formation of vacuoles.
The cytoskeleton does not represent a static structure but is able to disassemble and assemble its parts in order to enable the internal and overall mobility of the cell.
The cytoskeleton contributes to cell migration because cell motility is required for tissue construction and repair.
The cytoskeleton helps transport communication signals between cells.
In some cells, it creates cell bulges, such as cilia and flagella.
Cytoskeletal structure
:
The cytoskeleton is composed of at least three different types of fibers: microtubules, microfilaments, and middle filaments.
These fibers differ in their size, and the microtubules are the smallest and the microfilaments are the thinnest.
1) 35mL to L 1 L = 1000ml so, 35mL = 35÷1000=0.035L
2) 950gm = 1Kg =1000g SO, 950÷1000= 0.950 Kg
3) 275mm to cm= 1mm= 1÷10 cm so, 275÷10= 27.5cm
4)1000mL to L = 1L=1000ml so, it will equal to 1L
5)4500mg to g = 1mg= 1÷1000g so, it will equal to 4.5g
6)25cm to mm = 1cm= 10mm so, 25X 10= 250mm
7)0.005Kg to mg, so 1Kg= 10∧6 mg so, 0.005X10∧6= 5000mg
8)0.075m to cm, so 1m =100cm so, 0.075X100= 0.75cm
9)15 g to mg , so 1g = 1000mg so, 15X1000= 15000mg
Answer:
an organism with nutritional requirements
Explanation:
Answer:
scientific conclusions are reliable as they are helpful for many things however it is true that after the evolution of new ideas the old theory have some changes or may change fully or may be proved wrong but yeah the old theories are still helpful for many reasons and things.
so I think scientific conclusions are reliable
