in the microbiology world, is used to determine O Capability of a microbe to perform a specific enzymatic activity. O Staining characteristics. O Nucleic acid-base composition of DNA sequences.
Answer:
3.14g (3.s.f.)
Explanation:
change in mass = 0.25
mass at start = 7.96
percentage change in mass = 0.25/7.96 × 100
= 3.14g (3.s.f.)
This question is quite difficult
Answer: air, water, food
, a place to live
Explanation:
The living beings are composed of multiple cells, blood and water. They require certain necessities to survive and reproduce. The air is necessary for respiration. Water is necessary for fulfilling the thirst and maintaining the balance of fluid in the body. Food is necessary as it provides energy to do various biological functions. A place to live is necessary as it is the place where the living being rests, eat food and does other important activities.

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
