There are two different species of toads which are separated by a hot and dry valley, and fossil evidence indicates that these two species share a common ancestor. What would have caused these two species to evolve?

Answers

Answer 1

Answer:

Answer: Adaptive Speciation

Explanation:

The two species evolved as s result of adaptive Speciation.

Adaptive speciation occurs when biological interactions induce disruptive selection and the evolution of assortative mating, thus triggering the splitting

understanding processes of adaptive speciation, in which the splitting of lineages is an adaptation caused by frequency-dependent selection. Adaptive, or sympatric, speciation has been modeled since the 1960s.

Answer 2

Answer:

Answer:

adaptive speciation

Explanation:

In evolutionary biology, adaptive radiation/speciation is a process that makes living organisms diversify and change rapidly from an ancestral species into several new forms, especially when a change or natural event in their environment makes new resources available, thereby creating new challenges and opening new environmental niches.

Javier lives along the eastern coast of south carolina where his town recieves sea breezes during the day. He enjoys the breezes coming off the ocean. He knows land breezes occur at night. Describe what causes wind to form and wxplainthe ways sea and land breezes form

Answers

Answer:

Look below for answer

Explanation:

Wind is air in motion and is caused by the uneven heating of the earth's surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind: speed and direction.

Land and sea breezes develop because of differential heating and cooling of adjacent land and water surfaces. Water has a greater heat capacity than land, i.e. land absorbs and emits radiation more efficiently and faster.

Final answer:

Wind results from the movement and distribution of thermal energy, with warm air rising from heated land creating low-pressure zones that cooler air rushes to fill. Specific wind patterns like sea breezes and land breezes are shaped by the differential heating and cooling of land and water, with sea breezes occurring during the day, and land breezes, at night.

Explanation:

Wind formation is directly related to the movement and distribution of thermal energy on Earth. When the sun heats the Earth's surface, the air near it also becomes warmer. As a result, this heated air expands, becomes light, and rises. The rising warm air creates a lower pressure zone below it. To fill this lower pressure zone, cooler air from a high-pressure zone starts moving, which we perceive as wind.

The sea breeze and land breeze are specific wind patterns influenced by the unique thermal properties of water and land. A sea breeze develops during the day, when the land heats up faster than the nearby ocean, warming the air above it. This warmer air expands and rises, creating a lower pressure zone that winds from the relatively cooler and higher pressure over the ocean fill. As a result, the cooler air travels from the ocean to the land, creating a 'sea breeze.'

Conversely, at night, land cools down faster than water. The air above the ocean remains warmer and rises, leaving a lower pressure area filled by the cooler air from the land. This creates a land breeze flowing from the land towards the sea.

1) The Sun has an average surface temperature of approximately 6000 K. Calculate the power per unit area released by the surface of the Sun using Stefan-Boltzmann Law and report the value below. Units are a must. (2 points)Power per unit area released by the Sun=

Answers

Answer:

Power per unit area released by the Sun is 73,488,384 Watt per meter square.

Explanation:

The Sun has an average surface temperature of approximately,T= 6000 K

The power per unit area released by the surface of the Sun be P'

Stefan-Boltzmann Law is given as:

$P'=(Power)/(Area)=\sigma T^4$

where

$\sigma =5.6704* 10^(-8) Watt/m^2K^4$ Stefan-Boltzmann constant

T = Absolute temperature of the body

Power per unit area released by the Sun:

$=5.6704* 10^(-8) Watt/m^2K^4* (6000 K)^4=73,488,384 Watt/m^2$

How changing weather patterns affect food production, the spread of disease or damage to homes, transportation, or the electric grid

Answers

Answer:Reduced Crop production and yield due to erosion and bush fires.

Spread of Diseases through the spread of Bacteria and other pathogens.

Damage to Homes High sea level causing flooding.

transportation increased accidents due to reducing visibility.

Electric grid Damage caused by strong winds breaking down electric installations.

Explanation: Recently the sea levels have increased causing the water to flow into farmlands destroying Crops,high rate of wild fires destroying millions of Dollars worth of food crops.

Bacteria and other disease pathogens spread and become very active during warm temperatures, generally temperatures are getting warm due to the impact of Green house emissions.

Several millions of Dollars worth of Homes have been destroyed by high levels of flooding and wide fires.

The level of visibility is dropping by the day as can be seen in major cities around the world, leading to high rates of accidents.

Damage to Electric grids by Flooding,Strong winds, wild Bush fire etc.

2. weather graphs
3. climographs
4. barographs
5. rain graphs

Answers

Answer:

3. climographs

Explanation:

The climograph is a graphical representation of the climatic features such as the rainfall pattern and the temperature and the amount of the data is used for comparison of the yearly and monthly basis and has two or more variables are used to depict the differences.

Useful to understand the world climatic patterns of different regions in the world. They have wide application s are used in the military and time of the natural events.

By showing temperature, pressure and the rainfall and cloud and the humidity pattern found in a particular place they are a valuable tool if info for the modern-day weather.
