what is population density? What is the formula for calculating population density?​

Answers

Answer 1

Answer:

Explanation:

To calculate the population density, you will divide the population by the size of the area. Thus, Population Density = Number of People/Land Area. The unit of land area should be square miles or square kilometers.

During the process of mountain building, earthquakes sometimes occur along continental-continental convergent boundaries. Which statement best describes the motion of the plates along these boundaries that causes the earthquakes?

Answers

Answer:

Although you have not put the answer options, the movement of the plates in the situation shown above occurs with the approach of their continental plates that collide and bend due to the impact.

Explanation:

The converging movement of the plates indicates that two plates are moving towards each other until they collide. When these two plates are continental, the movement is called continental-continental convergent.

As the two continental plates have the same density, the impact between the two causes them to bend and not sink into each other.

The cause of humanity's increased water consumption is an increased population. What is the effect?

Answers

Option are not provided in the question. The complete question is as following:

The cause of humanity's increased water consumption is an increased population. What is the effect?

A. less potable water, a growing threat to biodiversity

B. more potable water, a growing threat to biodiversity

C. less potable water, a decreased threat to biodiversity

D. more potable water, a decreased threat to biodiversity

Answer:

A. less potable water, a growing threat to biodiversity

Explanation:

The increasing population of human causes increase in water consumption that leads to reduction in portable water, which is a growing threat to biodiversity .

Portable water or freshwater is used for drinking by humans beings along with that it provide habitat to many diverse marine wildlife and they are important to local ecosystems as they provide sources of income and food to humans and other wildlife.

Freshwater or portable water play very important role to control flood and erosion.

So, decrease in portable water result into decrease in biodiversity.

Hence, the correct option is A. less potable water, a growing threat to biodiversity .

Someone expressing a recessive hair color has _______.
A-1 dominant and 1 recessive allele for hair color
B-2 dominant alleles for hair color
C-2 recessive alleles for hair color

Answers

Answer: The answer would be C

Explanation: This is because in order to express a recessive trait one must have no dominant alleles or otherwise the dominant would win out and be expressed instead. For example, if a person had 1 allele for brown hair and 1  for red the brown would win and the same would happen if they had 2 brown hair alleles. Whereas if a person had two alleles for red hair and none for brown, only then would the red trait be expressed. Hope this helped!

Chimney swifts can easily adapt roosting behaviors to any structure made of the proper material C. Chimney swifts are nocturnal birds whose large numbers are evident in the size of their colonies D. Moving in large chipping flocks is a natural protection against predators Chimney swifts are small, slender birds that have become a symbol of summer for many. They usually appear in North America during warm, summer months as they make their way to more tropical sites for the winter. They are recognized most often as spectacular, chirping flocks moving through the sky in synchrony. Chimney swifts can be seen most vividly at dusk when large colonies of hundreds, or even thousands of individuals form tornado-like funnels as they descend into the chimneys. Unfortunately, the size of the colonies we see is misleading. Though the numbers may seem remarkable, chimney swift populations have been declining sharply since the 1970's due primarily to habitat loss. Unlike most birds, chimney swifts cannot perch or stand upright, so they require long, hollow spaces that are enclosed to provide safe roosting and nesting sites. Historically, chimney swifts preferred hollow trees. However, as pioneers colonized territory and replaced forests with towns, the species was forced to adapt by using other structures, such as chimneys. In the US, a large-scale shift to alternate heat sources, chimney- capping and the use of fabricated chimneys has drastically impacted their ability to nest during migration. Traditionally, chimneys were lined with clay, which the swifts were able to cling to and make their nests. Newer, prefabricated chimneys are often lined with metal flues Traditionally, chimneys were lined with clay, which the swifts were able to cling to and make their nests. Newer, prefabricated chimneys are often lined with metal flues that make it impossible for them to use. In addition, logging and deforestation may make finding suitable overwintering habitat more challenging than ever. In an effort to sustain the remaining population, conservation groups have designed supplemental housing structures, called "Chimney towers." These towers are designed specifically to provide roosting sites for chimney swifts. Chimney swifts now rely almost entirely on man-made structures like these to survive. However, because this species is remarkably adaptable, even minimal conservation efforts like keeping traditional masonry chimneys uncapped during the summer months can drastically improve their chance of survival.
