If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population
s344n2d4d5 [400]

<u>Given:</u>

Present population of bison = 3652

Maximum growth rate = 0.28

<u>To find:</u>

The population of bison after one year.

<u>Solution:</u>

The future population can be calculated with the help of the following formula,

P_F=P_P\times(1+r)^n

where P_F is the future population, P_P is the present population, r is the growth rate and n is the number of years.

On substituting the given values in the formula we get,

\Rightarrow P_F=3652\times(1+0.28)^1

\Rightarrow P_F=3652\times1.28\rightarrow4674.56\approx4675

Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.

Brums [2.3K]

Answer: asexual reproduction

Explanation:

From the question, we are informed that Brady took a cutting from a sweet potato vine in his family garden and placed the vine in a small vase filled with water. We are further told that after about a week, tiny roots had begun to grow. This is simply an example of asexual reproduction.

Asexual reproduction is simply refers to a form of reproduction which doesn't have to do with changing the chromosomes or gametes fution. In this case, the fact that tiny roots began to grow despite the fact that there was no fusion of gamete shows that it's an asexual reproduction.

Classifying the characteristics of dna, mrna, and trna determine from the description if each characteristic applies to dna, mrn
Jlenok [28]
The DNA, mRNA and tRNA are the essential nucleic acids that initiate protein synthesis. The DNA contains the genetic code of our human body in the form of chromosomes. It is composed of nucleic acids like uracil (U), guanine (G), adenine (A) and cytosine (C). The messenger RNA or mRNA carries this code called codons expressed in three-letter codes. Each amino acid has its own assignment of code. The mRNA carries this code to the ribosome which is the site for protein synthesis. The translational RNA or tRNA contains anti-codons to translate the codes in the mRNA into amino acids that link together to form proteins.

To measure the population of lake trout in a 250-hectare lake, 400 individual trout were netted and marked with a fin clip, then
kenny6666 [7]

Answer:

Estimated size is 1600

Explanation:

Given data:

Size of lake is 250 hectares

Total number of trout who netted is 400

Total number of trout in next week is 200

Total number of trout having fin clip 50

estimation population size is estimated by mark rupture as follow

Estimated population size = \frac{(marked\ initally \times total\ recaptured)}{mark\ recaptured}

Estimated size= \frac{400\times 200)}{50}

Estimated size is 1600

A student measures the length of a glass rod five times and records the data as: a. 23.487 cm b. 23.493 cm c. 23.516 cm d. 23.50
MAVERICK [17]
Percent error is calculated by the expression:

%error = |actual value - observed value| / actual value x 100

We calculate the error of the values as follows:

<span>a. 23.487 cm
% error = |</span><span>23.490  - 23.487| / 23.490 x 100 = 0.013%
</span><span>
b. 23.493 cm
</span>% error = |23.490  - 23.493| / 23.490 x 100 = 0.013%
<span>
c. 23.516 cm
</span>% error = |23.490  - 23.516| / 23.490 x 100 = 0.11%<span>

d. 23.501 cm
</span>% error = |23.490  - 23.501| / 23.490 x 100 = 0.05%<span>

e. 23.477 cm
</span>% error = |23.490  - 23.477| / 23.490 x 100 = 0.055%
