Answer;

-Birth rate

Explanation;

-The birth rate is the total number of live births per 1,000 in a population in a year or period. For example; in one year, 35 giraffes are born to a population.

-A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time. Scientists study a population by examining how individuals in that population interact with each other and how the population as a whole interacts with its environment.

What does topography show?

muminat

Answer:

I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.

II. The shape of the land.

Explanation:

In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a topographic map is used to graphically describe this features.

A topographic map can be defined as an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of the Earth.

A topographic map is a two-dimensional model that uses contour lines to represent points of equal elevation above sea level such as mountains, hills, plains, valley etc.

The two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.

Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface.

Hence,a topography show two (2) main things and these includes;

I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.

II. The shape of the land.

A convergent boundary is a location where tectonic plates move toward each other. which feature of the ocean floor is caused by

pav-90 [236]

Answer:

At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.

Identical population-splitting events occurred simultaneously on two neighboring islands, Islands B and C, which are each initia

sweet-ann [11.9K]

Answer:

This is due to the event of Speciation that happened for the rodents in Island B but not for the rodents in Island C.

Explanation:

Due to splitting of the population,

The sub-population of rodents formed in Island B are B1 and B2.
The sub-population of rodents formed in Island C are C1 and C2.
In case of Island B, each of the B1 and B2 sub-populations that got split from each other developed certain mutations that were necessary for them to adapt to the particular diverse environment each of them were exposed to, through the period of 50,000 years. These mutations were so varied that reproductive isolation was generated between them that resulted in each of them to develop into different species.Hence, speciation happens here and B1 and B2 are incapable of inter-breeding.
In case of Island C, each of the C1 and C2 sub-populations that got split might have got exposed to similar environmental change or no environmental change or the environmental change might have been too small to cause drastic change in each of the sub-populations. As a result of this the two sub-populations might have acquired certain mutations to adapt to the environment each of them were exposed to, through a period of 100,000 years. These mutations might not have been too variable or contrasting to cause reproductive isolation between C1 and C2. Hence, no new speciation happens here and C1 and C2 are capable of inter-breeding.

If a body's rectal temperature cannot be taken, what other location can be used?

The armpit isn't the most precise but it is close. Under the tongue, across the forehead, as long as you have the proper tools (thermometer, the thermometer meant for foreheads) you should get a fairly accurate reading.
