Answer:
sample C have the highest density
Explanation:
Data Given:
mass of sample A = 224.96 g
Convert g to kg
1 g = 0.001 Kg
224.96 g = 224.96 x 0.001 = 0.225 kg
mass of sample B = 0.55632 Ibs
Convert lbs to kg
2.21 lb = 1 kg
0.55632 Ibs = 0.55632 / 2 = 0.278 kg
mass of sample C = 0.30648 kg
Solution:
To calculate density of every sample we have the following formula
d = m/v . . . . . . . . . . (1)
It is clear from the formula that density have direct relation with mass and inverse relation with volume, that is density increase with increasing in mass.
As we have same volume of wood sample, so suppose that each sample have volume of 2 cm³
So now we find density for each sample
As for sample A
- mass of sample A = 0.225 kg
Put values in formula 1
d = 0.225 kg / 2 cm³
d = 0.128 kg/cm³
As for sample B
- mass of sample A = 0.278 kg
Put values in formula 1
d = 0.278 kg / 2 cm³
d = 0.139 kg/cm³
As for sample C
- mass of sample C = 0.30648 kg
Put values in formula 1
d = 0.30648 kg / 2 cm³
d = 0.153 kg/cm³
So it shows that sample C have the highest density that is 0.153 kg/cm³ . As it have the highest mass too among all samples.
Answer:
2 half lives.
Explanation:
Suppose there are 100g of parent isotope at the start.
After 1 half-life there will be 50g of parent and 50g of daughter isotope.
After another half life there is 25 g of parent and 75g of daughter isotope.
Answer:
<h2>Dog's mitochondria lack the transport protein that transport pyruvate ( end product of glycolysis) across the outer mitochondrial membrane
.</h2>
Explanation:
1. As given here that dog's mitochondria can use only fatty acids and also amino acids for their respiration, and as compared to others, Dong's cell produce more lactate then normal, this indicate that his mitochondrial membrane is different then others.
2. The aerobic phases of cellular respiration in eukaryotes occur within mitochondria. These aerobic phases are the TCA Cycle and the electron transport chain. Glycolysis occurs in the cytoplasm and the products of glycolysis enter into the mitochondria to continue cellular respiration.
3. These condition shows that dog's mitochondria lack the transport protein of mitochondria that moves pyruvate across the outer mitochondrial membrane.
