You mix activated yeast with different carbohydrates and measure the CO2 production over a time span of 10 minutes for each type

of carbohydrate. Is this experiment a qualitative analysis or a quantitative analysis

Answer:

quantitative analysis

Explanation:

Qualitative analysis refers to quality whereas quatitative analysis refers to the amount or quantity. In this experiment, we see how much carbondioxide gas is produced after the use of different carbohydrates given to the yeast. In this experiment, we want to know the concentration of the product in the reaction not the quality so we can say that this experiment shows quantitative analysis as compared to qualitative analysis.

Cross bridge formation between myosin heads and actin molecules is caused by the elevation of calcium ion concentration in the c
almond37 [142]

Answer:

sarcoplasmic reticulum deteriorates and ATP production is stopped

Explanation:

Rigor mortis is the third stage of death characterized by stiffening of joints and muscles in body. The stiffening occurs because muscles are not able to return to the relaxed state. There are two reasons for rigor mortis, depletion of ATP and increase in calcium concentration in cytosol. Due to these factors the actin-myosin crossbridge is not able to break and the muscles remain in contracted state.

Sarcoplasmic reticulum deteriorates and calcium is released into the cytosol. Sarcolemma ( covering of muscle fiber ) also breaks down releasing extra calcium into the cytosol. Calcium is responsible for formation of actin-myosin cross bridge and when its concentration increases the bridge is formed continuously leading to stiffening of muscles and joints.

What is the correct term for variation in characteristics within populations of the same species? A variation in characteristics
Crazy boy [7]

Answer:

The correct answer would be phenotypic variation.

Phenotype refers to observable traits or characteristics of an individual. For example, height, color, shape, et cetera.

Phenotypic variation refers to the sum total of variations in characteristics within populations of the same species.

In contrast, genotypic variation refers to the sum total of variations (such as allele frequency) present in the genome of populations of the same species.

The distribution of water between intra- and extra-cellular spaces depends on concentration differences of _____, or dissolved s
Aleks04 [339]

Answer:

Solutes

Explanation:

According to my research on studies conducted by various chemists, I can say that based on the information provided within the question this depends on concentration differences of Solutes. This although already defined in the question, is the minor component in a solution, it is the component that gets dissolved in the solvent.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
