Answer:
K-Pb
Explanation:
because according to the radioactive elements it is because the rock cannot express its feeling buy you can see by it's texture how it feels about your decision
<h2>Given statement is false</h2>
Explanation:
According to dispersive model of DNA replication,DNA molecules are hybrids of parental and daughter DNA;In this model each individual strand is a combination of original and new DNA
Meselson and Stahl did an experiment on DNA replication using E.coli bacteria
- E.coli was grown in a medium containing heavy isotope of nitrogen,bacteria took up the nitrogen and used to synthesize new biological molecules,including DNA
- It was grown for many generations,the nitrogenous bases of the bacteria's DNA were all labelled with heavy nitrogen
- Bacteria were then switched to light nitrogen isotope and allowed to grow for several generations
- They then measured the density of the DNA using density gradient centrifugation
- This method separates molecules such as DNA into bands by spinning them at high speeds in the presence of another molecule, such as cesium chloride
- Each DNA produced two DNA molecules each with one new strand and one old strand called semi conservative replication(half of the parental DNA conserved in daughter DNA)
- Each DNA strand act as a template for synthesis of new strand
- Hence,dispersive model of DNA was eliminated and semi-conservative model of DNA replication was proved by the above experiment
The statement that best describes the Americans who served in the Vietnam war was most of the US soldiers were all young, working class volunteers. The correct answer is D.
Answer:
Biology is the scientific study of life.[1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.[1][2][3] For instance, all living organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.[1][2][3] Finally, all living organisms require energy to move, grow, and reproduce, as well as to regulate their own internal environment.[

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
