Answer:

Earth is in the midst of its sixth mass extinction: Somewhere between 30 and 159 species disappear every day, thanks largely to humans, and more than 300 types of mammals, birds, reptiles, and amphibians have vanished since 1500. These rates do not bode well for the future of life on our planet, but what if extinction wasn’t permanent? What if we could resurrect some of the species we’ve lost?

For decades the notion of “de-extinction” hovered on the scientific fringes, but new advances in genetic engineering, especially the CRISPR-Cas9 revolution, have researchers believing that it’s time to start thinking seriously about which animals we might be able to bring back, and which ones would do the most good for the ecosystems they left behind.

It is A

Explanation:

Two pathways come from the heart: The pulmonary circulation is a short loop from the heart to the lungs and back again. The systemic circulation carries blood from the heart to all the other parts of the body and back again.

Answer:

In most cases, no.

Explanation:

Some basic needs of an organism are an appropriate environment ( E.g. Having water for fishes, be it salty or fresh), have a reasonable temperature and pH value of its surroundings, and having enough food to sustain itself. You can even look at things like air composition.

There's no way an organism that normally lives in slightly alkaline water can survive in water with a pH of 3. Similarly, organisms can't survive in unsuitable temperatures, like how a polar bear can't survive in the desert.

In cases like food, they would die from starvation without appropriate amounts of food.

In essence, an organism is not likely to be able to grow in environments that do not meet their needs.

Some organisms adapt and change over time depending on the organisms, but most of them may die before adulthood.

Answer:

All electromagnetic fields (EM waves) consist of two component fields, electric fields (E fields) and magnetic fields (H fields). E fields and H fields are companions and together make up the total EM field. Where one is, so is the other

Answer:

NASA studied astronaut twins Mark & Scott Kelly to determine the effects of staying in space for a year. ... Space presents unique stresses to the human body. With lower gravity levels, for example, bones and muscles are more likely to become weak since they no longer have to support the weight of the body.

Answer:

Asteroid-small,rocky objects that orbit the sun

Axis-a real or imaginary line that something rotates on

Comet-cosmic balls of frozen gasses,rocks,and dust that orbit the sun

Diameter-a straight line that runs from one side of a figure and passes through the middle

Gravity-an invisible force that pulls objects towards each other

Kuiper Belt-an icy ring of frozen objects just outside of the planet Neptune’s orbit

Latitude-the measurement of distance north or south of the equator

Orbit-a regularly repeated path that one object in space takes around another

Revolution-the action of a celestial body going around in an orbit;the time taken by a celestial body to make a complete orbit;the rotation of a celestial body on its axis

Rotate-the process/act of turning or circling around something

Rotation-the action/process of rotating on/as if on an axis or center

System-a group of related things that work together as a whole

Theory-a plausible or scientifically acceptable principle/body of principles offered to explain something

Explanation:

Answer: You can clean the water pollution by the water bottle activity.

Explanation:

You can do the water bottle filteration. From your house, you should find a large soda bottle or water bottle. YOu layer it with sand and gravel at the bottom. Line the top of the bottle with a coffee filter. This will allow for a natural filtration system.

You can find this on many science experiments websites because it is a common science fair project.

Search tool would be: homemade water filter

Answer:The summer solstice occurs at the moment the earth's tilt toward from the sun is at a maximum. Therefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice.  The summer solstice occurs when the sun is directly over the Tropic of Cancer, which is located at 23.5° latitude North, and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China.  For every place north of the Tropic of Cancer, the sun is at its highest point in the sky and this is the longest day of the year.

The winter solstice marks the shortest day and longest night of the year. In the Northern Hemisphere, it occurs when the sun is directly over the Tropic of Capricorn, which is located at 23.5° south of the equator and runs through Australia, Chile, southern Brazil, and northern South Africa.
