Answer,

Ribosomes

Explanation,

Ribosomes are cell organelles which help to produce proteins.It contains RNA and DNA strands which help in formation of new proteins.The synthesis of proteins takes place in two stages  transcription and translation.Transcription takes the information encoded to the DNA and encodes it into mRNA which heads to the nucleus inthe cytoplasm.Translation mRNA works with a ribosome and tRNA to synthesize proteins.

I need help with this (#20)
tester [92]

Answer:

a Anaphase I

b Metaphase I

c Telophase I

d Anaphase II

e Prophase I

f Telophase II

Explanation:

Prophase I begins after the DNA has been duplicated, as shown in picture e. The chromosomes are condensed, and also visible, which is apparent in picture e.

The next stage is called Metaphase I, in which the pairs of homologous chromosomes align at The the centre of the cell and the spindle fibres attach, as shown in picture b.

The pairs of chromosomes are pulled apart to opposite poles of the cell by the spindle fibres., as shown in picture a. This stage is called Anaphase I.

Then, a process called Telophase I occurs, when the cell divides into two daughter cells. One of these cells is shown in picture c.

Picture d shows the stage Anaphase II, where the spindle has attached and the chromatids are pulled to the opposite poles of the cell.

The final picture left is picture f, which shows the daughter cell at the end of meiosis II, where the nuclear envelope is reforming, as in telophase II.

Amino acids are usually taken up into animal cells using a coupled transport system in the plasma membrane. Clearly stated in th
exis [7]

Answer:

It requires energy

Explanation:

In the coupled transport system, coupled carriers couple the inward transport of one solute across the membrane to the outward transport of other solutes across the membrane. The tight bonding that occurs between the transport of two solutes allows these carriers to utilize the energy stored in one solute, usually an ion, to facilitate transport of the other. With this way, the free energy released during the movement of an ion down an electrochemical gradient is utilized as the driving force to transport other solutes inwards, against their electrochemical gradient.
