How do you calculate population time?

Answers

Answer 1

To figure out how long it would take a population to double at a single rate of growth, we can use a simple formula known as the Rule of 70. Basically, you can find the doubling time (in years) by dividing 70 by the annual growth rate.

How do you calculate population over time?

Population Growth Calculation To calculate the Population Growth (PG) we find the difference (subtract) between the initial population and the population at Time 1, then divide by the initial population and multiply by 100. The Population Growth Rate (PGR) for that period of time (10 years) was 12%.

How to calculate population?

The best way to measure the size of a population is to count all the individuals in that population. When determining the population sizes of trees or other relatively immobile organisms, this method is practical. If the organism is mobile, however, such as a fish, counting every individual would be difficult.

Answers

Genotype frequency is the percentage of the population that has a certain genotype. In this case, the population of birds has two genotypes: BB (blue tail feathers) and Bb (blue tail feathers). The population has a total of 100 birds.

The population has 16 birds with the Bb genotype and 84 birds with the BB genotype. To calculate the genotype frequency, we divide the number of birds with each genotype by the total number of birds: 16/100 for the Bb genotype and 84/100 for the BB genotype.

In conclusion, the genotype frequency of this population of birds is 16% for Bb and 84% for BB. Blue tail feathers are the dominant trait, meaning that the BB genotype is the most common genotype in the population.

Answers

a.)Optimal temperature for amylase is 37 degrees Celsius.

b.)Tube 1 and tube 7 have the same results because they are both at optimal temperature for amylase.

c.)Tube 2 and tube 5 have the same results because they are both not at optimal temperature for amylase   

Amylase is an enzyme that is found in saliva, pancreatic fluid, and in small intestine mucus. It aids in the digestion of carbohydrates. The colour results for tube 1 and tube 7 indicate that the enzyme is active and that the substrates are being converted to products for the Benedict's test. Tube 2 and tube 5 indicate that the enzyme is active, but the substrates are not being converted to products because they are not at the optimal temperature for amylase, and thus the reaction proceeds more slowly.

Which solution has the higher percent of the acid a 0.10m solution of hc2h3o2

Answers

To determine which solution has a higher percentage of acid, we need to compare the concentrations of the acid in the solutions. In this case, we have a 0.10 M solution of HC2H3O2 (acetic acid).

To calculate the percentage of acid in the solution, we need to determine the molar mass of acetic acid, which is 60.052 g/mol. Then we can use the following formula:

Percentage of acid = (Molar mass of acid / Molarity of solution) * 100

For the 0.10 M solution of HC2H3O2:

Percentage of acid = (60.052 g/mol / 0.10 mol/L) * 100Percentage of acid ≈ 600.52%

Therefore, the 0.10 M solution of HC2H3O2 has a higher percentage of acid, approximately 600.52%.

D. If one becomes damaged, the other can take over.

Answers

Answer:

a

Explanation:

Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not green. Because green is reflected or transmitted, chlorophyll appears green. Carotenoids absorb in the short-wavelength blue region, and reflect the longer yellow, red, and orange wavelengths.

As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

Dr. DeRidder lesions, or damages, the ventromedial hypothalamus in one group of rats and the lateral hypothalamus in another group. What effect might he expect on the eating behavior of each group of rats? Both groups should begin overeating and become grossly obese. Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating. Both groups should stop eating and perhaps eventually starve to death. Rats with ventromedial lesions should stop eating; rats with lateral lesions should begin overeating.

Answers

Answer:

Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating

Explanation:

The feeling of hunger stimulates a desire to eat.

The lateral hypothalamus is responsible for making an organism hunger and craves for food upon receiving any stimulation or signal that causes hunger.

A damaged to the lateral hypothalamus would mean the organism would not be able to sense hunger and thus, there would be no desire to eat. Hence, the rats with lateral lesions should stop eating.

On the other hand, the ventromedial hypothalamus is responsible for quenching hunger and signaling to the organism that it is full, hence, it would stop eating. However, when the ventromedial hypothalamus is damaged, the organism would not be able to tell when to stop eating. Hence, rats with ventromedial lesions should begin overeating.
