Centrioles is the organelle.
Answer:
A) many noncoding stretches of nucleotides are present in mRNA.
Explanation:
A transcription unit in eukaryotes includes the region that code for mRNA extending from the 5' cap site to the 3' poly-A site. It also includes the controlling regions. The mRNA formed by transcription also has some non-coding intervening sequences. These are called introns. Introns are removed from the primary transcripts by the process of splicing that occurs after transcription.
Therefore, a transcription unit that is 8,000 nucleotides long may use only 1,200 nucleotides to code for a protein having 400 amino acids since the rest of the nucleotides are part of introns and are removed from mRNA after transcription.

Photosynthesis is done only by plants by using sunlight water and CO2
All living organisms can do cellular repirations
She is wrong because she said plants only do photosynthesis but that's not true because trees do cellular repiration too because when there is no sunlight they need energy. So what they do is they break down the sugar doing glycolysis by using mitochondria. Sidenote:Both plants and animals have mitochondria in their cells.They need energy right when there is no sun.So they use glycolysis.Glyco means sugar and lysis means break down.Then there come 2 steps.
Aerobic Respiration
Anaerobic Repiration
If the sugar that we just break down contains oxygen the that sugar falls to the aerobic respiration
If it does not contain sugar it goes to Anaerobic Respiration
Aerobic Respiration : It would use Kreb Cycle to Make 2 ATP.ATP is for Adension Tri Phosphate. Which is basically enregy.Then there comes Electron Transport Chain.Where they use protons to gain 32 ATP.Overall
2 ATp from glycolysis 2 from Kreb Cycle and 36 from ETC so 36
Anerobic: They fall part to 2 major respirations of this section which are
1. Alcoholic Repiration - It contains no oxygen, gain 2 atp and used to make breads and alcohol
2.Lactic Acid - gain 2 ATp and no oxygen and used in yogurt you eat and it creates sore in your muscles
She is wrong because that is completely wrong statement that trees only do photosynthesis but no they use cellular Respiration to gain energy from ATP when there is no sun available to them
Hope that answers the question
The density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors such as; availability of food, predation, disease, and migration.
