The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.

Speciation can be defined as a process that births new species with different traits while they evolve.

Speciation occurs when extinction is eminent and most time in other to preserve that race they evolve into something new with new traits.

They are easier to build than conventional rockets.

A prevailing wind coming from the North Pole would each type of prevailing wind have on the land it crosses.

The trade winds, prevailing westerlies, and polar easterlies are the three predominant wind belts connected with these cells.

Although prevailing winds frequently come from the north sea and provide moisture to the land, they can also bring moisture to the land. There is no moisture or water involved when wind comes from a land location. This means that the winds bring more dry air into the atmosphere, reducing the likelihood of rain.

Which of the following could be a hypothesis for what a rattlesnake eats ?

A. If there are no mice an ecosystem a rattle snakes moves to another ecosystem

B. The remains of mice have been found in the stomach contents of rattlesnakes

C. A rattlesnake eats mice and other small rodents

D. What food sources are available in the snakes habitat

If there are no mice in an ecosystem a rattlesnake moves to another ecosystem. this could be a hypothesis for what a rattlesnake eats. Thus, option "A" is correct.

A hypothesis is a prediction made before an experiment is carried out. If [CAUSE], then [EFFECT], because [RATIONALE], is a popular format.

Strong hypotheses in the area of experience optimization are made up of three parts: a problem statement, a proposed solution, and an outcome.

Here the snake moving to a different habitat is the (EFFECT) because of the absence of mice in the environment (CAUSE). hence the RATIONALE is that rattlesnake feeds on the mice.

Thus, option "A" is correct.

Answer:

Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP).

Explanation:

If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentration in the extracellular fluid, the cell must use energy to move the substance. Some active transport mechanisms move small-molecular weight material, such as ions, through the membrane.

In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.

More condensation nuclei, more cloud formation and precipitation are the results of spraying aerosols into the atmosphere.

Aerosols greatly influence clouds formation and its growth. Water droplets gather readily around particles which provides a particle-rich atmosphere that promotes cloud formation.

So we can conclude that more condensation nuclei, more cloud formation and precipitation are the results of spraying aerosols into the atmosphere.

Natural selection has to do with organisms being best suited for their environment surviving and reproducing more often.

It is a process by which living organisms evolve.

The natural selection theory was proposed by Darwin. It states that organisms with traits that enable them to adapt better to the environment survive better and contribute more to the future population.

In the process of reproduction, the adaptive traits are passed to future generations. Thus, the future generation would be made up of individuals with adaptive traits.

Weak individuals without the adaptive traits gradually fade off from the population.

Research questions are phenomena being queried upon which a research is set up. The results from the research will answer the questions being asked.

Hypotheses, on the other hand, are tentative guesses made before conducting the experiment associated with the research. They are falsifiable statements of what the answers to the research questions will be. If the results support the statements, they are accepted, otherwise, they are further scrutinized scientifically.

There are many reasons are specific to the plant and our needs but remember this, without us modifying plants we would have been extinct thousands of years ago, everything you eat today does not exist in nature and if it does exist is either inedible, toxic, or too small to provide important nutrition.

When the tissues of plants are joined together to let them continue their growth together as one, then such a practice is known as grafting.

Grafting is commonly practised in horticulture and agriculture for the growth of commercially important plants in an asexual manner.

In the process of grafting, the upper part of the combined plant is known as the scion and the lower part is known as the stock.

Lymph is a fluid similar in composition to blood plasma. It is derived from blood plasma as fluids pass through capillary walls at the arterial end.

The lymphatic system collects excess fluid that drains from cells and tissue throughout the body and returns it to the bloodstream, which is then recirculated through the body.

If the La Nina occurs, the Jetstream will be further north during the event. This has to do with the chilly temperature in the Great Lakes.

Strong winds carry warm water towards Asia during La Nia episodes, causing upwelling along the west coast of the Americas. This means that in the Pacific, cold, nutrient-rich water rises to the top, pushing the jet stream northward.

In the winter, La Nina is associated with drier and warmer weather, which shifts to snowstorms in a northerly direction.

The lower southern region will have drier circumstances, while Florida will experience warmer than normal temperatures. As a result, Florida's winters will be moderate, with temperatures ranging from 5 to 18 degrees Celsius.

As a result, it will not experience the same conditions as the winter El Nino.

Why didn't the Voyagers fly by Pluto? Both Voyagers flew beyond the orbit of Pluto/Neptune in 1989, but neither flew by Pluto, which was elsewhere in its orbit at the time. It was never planned that the Voyagers would visit Pluto. The original mission of Voyager was to explore Jupiter and Saturn.

The antifreeze molecules allow icefish to live in subfreezing water by filling voids in existing small ice crystals and preventing the annexe of more ice molecules. Ice crystal development is thus effectively prevented.

Antifreeze proteins (AFPs) are natural antifreeze components initially seen in polar fish; AFPs can attach to ice and thereafter inhibit the development of the ice crystals. Fish can inhabit (−0.7 °C) of their blood serum by the integrity of AFPs.

The San Andreas Fault System has a historic record of moderate to great earthquakes. The surficial expressions of the two greatest historic earthquakes on the San Andreas are fairly well documented. The great San Francisco earthquake of 1906 was similar in magnitude to the great Fort Tejon earthquake of 1857.

The rate of movement was observed in this experiment as 0.25 m/ hour.

A rate of movement is essentially a speed measurement, where you divide the distance crossed from point A to point B by the time it took to do it.

o, we know the snail moved a total distance of 0.5 meters. that's our distance crossed.

We know that took 2 hours.  so we just have to calculate that:

0.5 meters / 2 hours  = 0.25 m/hour
