A beaver population of 15,000 experiences 1,000 births and 3,000 deaths in a year. Apply the growth rate equation to determine the beaver population's growth rate for the year.
The beaver population's growth rate for the current year is -13.33%.
Data and Calculations:
Past population of beaver = 15,000
Births this year = 1,000
Deaths in the year = 3,000
Decrease = 2,000 (1,000 - 3,000)
Present population of beaver = 13,000 (15,000 + 1,000 - 3,000)
Growth rate equation = (Present Population/Past Population)^1/n - 1
= (Present Population - Past Population)/Past Population x 100
= (13,000 - 15,000)/15,000 x 100
= -2,000/15,000 x 100
= -13.33%
Thus, the beaver population's growth rate for the year is negative, showing a decrease of 13.33% or 2,000 persons.

Adult size basketballs have a radius of approximately 12 cm.
Calculate the volume of air needed to fill the basketball to the nearest whole
number
Include the proper units.
Answer:
The volume of air needed is 603 cm³.
Explanation:
In general, basketball has a size of a sphere, so you have to find the volume of sphere using the formula :
[tex]v = \frac{4}{3} \pi {r}^{2} [/tex]
[tex]let \: r = 12[/tex]
[tex]v = \frac{4}{3} \times \pi \times {12}^{2} [/tex]
[tex]v = \frac{4}{3} \times \pi \times 144[/tex]
[tex]v = 192\pi[/tex]
[tex]v = 603 \: {cm}^{3} (near. \: whole \: no)[/tex]
Describe the Mexican immigrants in Texas. Why did they emigrate from Mexico to Texas? What are some examples of their culture in Texas?
Answer: Mexican Texas is the historiographical name used to refer to the era of Texan history between 1821 and 1836, when it was part of Mexico. Mexico gained independence in 1821 after winning its war against Spain, which began in 1810. Initially, Mexican Texas operated similarly to Spanish Texas. Ratification of the 1824 Constitution of Mexico created a federal structure, and the province of Tejas was joined with the province of Coahuila to form the state of Coahuila y Tejas.

Today Russia has tried to overcome the
Friction of Space by building the
A. Bullet Train
B. Orient Express
C. Blue Train
D. Trans-Siberian Railroad
Answer:
Russia has built the Trans-Siberian Railroad to overcome the Friction of Space.
Explanation:
Russia is the largest country in the world, and on top of it, its territory is stretched by longitude which creates a situation where from the easternmost to westernmost point the distance is incredibly big. As both the eastern and western coasts are strategically very important for Russia, it is crucial that they are connected with infrastructure that will enable relatively fast and cheap transportation and traveling.
The solution came in the form of the Trans-Siberian Railroad. This is the longest railroad in the world, starting from Saint Petersburg, diverging into two lines, one going to Tyumen but before that at Yekaterinburg turning to merge with the other line at Chelyabinsk, continuing to Chita where it diverges again with one line going through Khabarovsk to Vladivostok while the other moving slightly through Mongolia, Harbin in China, and ending in Vladivostok.

What do the above calculations tell you about the relationship between surface dew point and cloud height?
Answer:
Explanation:
From calculations we make and answers we get, we can tell that the smaller the difference between the air temperature and the dew point temperature, the lower the cloud base will be. Also, the bigger the difference between the air temperature and the dew point temperature, the higher the cloud base will be.
When there is convective cloud one can get a good approximation of the cloud base by using the formula Dewpoint Depression (Temperature - Dewpoint in °C) multiplied by 400ft.

What determines an organism’s traits at the molecular scale?
Answer:
Genes Have Alleles
The traits an organism displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype.
An organism's traits at the molecular scale displays are ultimately determined by the genes it inherited from its parents, in other words by its genotype.
What is a genotype?Genotype refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism. Humans are diploid organisms, which means that they have two alleles at each genetic position, or locus, with one allele inherited from each parent.
Each pair of alleles represents the genotype of a specific gene. Each plant's genotype contributes to its phenotype, which, in this case, is the outward appearance of its flowers. A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ.
The process of determining a genotype is called genotyping.
