C. Sublimation
Answers
Answer:
B/Transpiration
Explanation:
Transpiration is evap- oration of liquid water from plants and trees into the atmosphere. Nearly all (99%) of all water that enters the roots transpires into the atmosphere. ... Sublimation is the process where ice and snow (a solid) changes into water vapor (a gas) without moving through the liquid phase
There are different forms of energy and one form of energy can be converted into another. When we light a wax candle, the process is highly exothermic and on burning, the chemical energy of the wax gets converted into heat and light. A good source of energy is to be selected for the choice of work to be done. In ancient times, wood was the most common source of heat energy. We, in our daily lives, use various energy sources for doing the work. Nowadays we use diesel and electricity to run trains. We also use fossil fuels in vehicles which has some serious disadvantages, mainly air pollution. The recent example of air pollution was ‘Smog’ in the National Capital Region of Delhi. This pollution was a result of burning ‘Parali’ in northern states of the country, which affected the eyes and also caused serious respiratory problems.

Science !!
PICTURE BELOW
Answers
Answer:
thats crazyyyy
Explanation:
Woolly mammoths developed thick fur and large ears to survive in cold climates through natural selection.
The cold climate of the Pleistocene epoch favored the survival of animals that were well-adapted to cold weather. Woolly mammoths had thick coats of fur that helped to keep them warm, and they also had large ears that helped to dissipate heat. Woolly mammoths had a long trunk.
The trunk of the woolly mammoth was used for a variety of purposes, including gathering food, drinking water, and communicating with other mammoths. The trunk was also a valuable tool for helping the mammoth to survive in cold weather.
For example, the mammoth could use its trunk to blow snow away from its food or to reach food that was buried under the snow. Woolly mammoths were social animals. Woolly mammoths lived in herds, which helped them to survive in cold weather. The herds provided protection from predators and helped to keep the mammoths warm.

Answers
The given question is incomplete, the complete question is:
Consider a scenario where a native plant population is growing at it's carrying capacity in a community. The seed of an invasive species is brought in by a squirrel, which then germinates, grows and reproduces resulting in the establishment a population of this invasive plant species. The invasive species has very similar niche as the native plant species. How do you predict the native plant population to be affected by the presence of this invasive species?
The invasive species fitness will be limited by the native plant species
The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
There will be no change to the native plant population
The invasive species will grow unchecked and exponentially
No listed answer is correct
Answer:
The correct statement is the fourth one, that is, the invasive species will grow exponentially and unchecked.
Explanation:
The fitness of the invasive species will not get restricted by the native species. Though the opposite takes place as the original niche of the local species does not possess the natural predator for the invasive species. Therefore, invasive species emerge fitter and reproduce exponentially without population control.
The carrying capacity of the native species will not go down before the arrival of the invasive species, however, will go down post its arrival.
As the invasive species has no natural predators, one can witness a substantial reduction in the population of the local plant population. The invasive species will utilize the niche of the local plant, therefore, resulting in the reduction of the native species population, as they have share habitat, food resources, and other natural resources.
It is correct that the invasive species will grow without any control. An outbreak of invasive species generally takes place due to the absence of its natural predators in the ecosystem at the time of its introduction. Hence, the correct statement is the fourth one.
Invasive species establish in a new area, overgrow, and negatively interact with native species. The correct option is 4). The invasive species will grow unchecked and exponentially
-----------------------------------
Let us firts reviw some framework.
When talking about dispersion, we refer to the change in a species' range or distribution area.
When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their
• reproductive rate,
• population growth, and
• interaction with native species.
The introduction of invasive species has ecological, economic, socio-cultural consequences.
Once an invasive species has been established, it overgrows.
In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.
These factors favor their establishment because they are adapted to surviving under harder conditions.
They interact with native species by competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.
They can also become significant predators of native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.
They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.
They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
As they expand, they can also affect human in an economic manner and has socio-cultural effects. Many invasive species might cause crops loss by eating cultures. They attack farm animals. They affect buildings and other structures or ships by eating wood. They might even attack humans and cause health problems.
According to this information, we can answer the question.
We need to predict how NATIVE species are affected by INVASIVE species.
The options are,
1) The invasive species fitness will be limited by the native plant species
When talking about invasive species, this is not an option. Invasive species always affect the fitness of native species. So this option is not correct.
2) The native plant carrying capacity will go down, relative to that prior to the invasive species arrival
The carrying capacity will still be the same. But resources availability will decrease faster because both species have the same requirements. They compete for the same resources. This option is not correct.
3) There will be no change to the native plant population
The will occur changes for the native population for sure. It will be affected by the presence of invasive species. So this option is not correct.
4) The invasive species will grow unchecked and exponentially
Invasive species population will express an uncontrol exponential growth during its establishment phase.
This plant species find the perfect conditions to reproduce and increase its population size.
It finds available space, no predators, water and nutrients availability, proper light exposure, among others.
They can successfully compete with native species, displacing them and getting more space.
THIS IS THE CORRECT OPTION
5) No listed answer is correct
Not correct

Explain how precipitation happens. Use complete sentences and give at least two supporting details.
Answers
Answer:
In a general aspect, humid and warm air moves to lower latitudes or in altitude, losing heat and getting colder. Its humidity condenses and causes precipitation. Depending on the air movement there are different kinds of rain.
Explanation:
At a global level, it occurs unequal warming of the atmosphere, which depends on many factors and varies with latitude. This occurs because solar radiation reaches the earth differently at different latitudes, resulting in big convective cells of atmospheric circulation: Hardley cell, Ferrel cell, and Polar cell.
A convective cell is the movement of the humid air among different latitudes. Air moves from higher latitudes to lower latitudes, getting warm, getting less dense, and ascending. As the air gets higher in altitude, it´s density and pressure decrease, so the air tends to expand with elevation in response to the reduced pressure. Gases in expansion experiment adiabatic cooling, losing caloric energy as their molecules move getting farther away from each other. As the air gets higher, it gets colder, and hence, denser. The result is that descends again. Humidity gets denser and precipitates.
• Rain is controlled by temperature on the earth´s surface, atmospheric global air circulation, the position of the mountains and oceans, closure to the oceans.
• There are different kinds of precipitations according to their origin.
i. Convective precipitation: These are the most typical ones. Air gets warmer and less dense, elevating in altitude with humidity. On the way, it starts to get colder, and the humidity condenses, resulting in precipitation. Depending o the degree of condensation, the precipitation might be in a liquid state (rain), semisolid-state (snow), or solid-state (hail).
ii. Frontal Precipitations: They occur when a polar front coming from higher latitudes collide with a warm front coming from lower latitudes, resulting in a strong rain. This is typical of grasslands or temperate forests (approximately 40 º latitude)
iii. Orographic Precipitations: They occur when humid wind ascends by a mountain range, causing its adiabatic cooling, condensing the humidity, and precipitating.

Why is it important to understand challenges in a species environment in order to understand the species evolution? Relate your answer to what Darwin referred to as "the struggle for survival"
Answers
Answer:
The Struggle for Survival refers to the fight between organisms to survive by having access to the increasingly scarce resources in the environment brought upon by population increase.
Darwin believed that evolution was brought about by external pressures arising from this struggle for survival as species would have to adapt to the unique challenges in their environment to be able to better access resources.
This is why one must understand the challenges in an environment to understand why species in that environment evolved the way they did.
What is the difference between domestication and natural selection?
Answers
Answer:
By definition, natural selection is the survival of the fittest.
Explanation:
Natural selection, in itself, is not a generator or creator of evolutionary novelties, but it only exposes certain variants.
Variants do not arise under the induction of the environment, but randomly, by chance, by a combination of genetic material, something that already exists in the genetic fund of a species.
Domestication is a term used for the process by which various biological organisms adapt to survive in society or through the work of human beings.
