When scientists discuss objects that might hit Earth, what term do they use to describe them as a group?
near-Earth objects
asteroids and comets
Shoemaker-Levy 9
celestial bodies
Answer:
A. near-Earth objects.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.
A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.
Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.
Hence, near-Earth objects may pose a collision danger to planet earth.

A. Increase in biodiversity
B. Decrease in biodiversity
C. Increase in the overall health of the ecosystem
D. Decrease in the overall health of the ecosystem
Answer:

Biodiversity comes from having multiple types of organisms. This also allows different organisms to eat and create nutrients that is needed by all other organisms in the ecosystem.
What is the equation for calculating the change in water potential? In other words, this equation allows you to determine which way the water will move in response to two different concentrations.
Answer:
The correct answer is - Ψ = ΨS + ΨP.
Explanation:
The movement of the water in a solution where is two different concentrations present can be determined by measuring the water potential (Ψ).
Water potential (Ψ) can be determined by the equation that depends on these two factors osmotic potential represent by ΨS and pressure potential represent by ΨP.
Ψ = ΨS + ΨP.

Although scientists are unable to explore the Sun's layers directly with instruments, they can measure the change in the speeds of the surface layers and the temperature of those layers from Earth Using this data, scientists have created models of the Sun and we
now know that the sunspots that form on the surface are the areas of coolest temperature for this stat. At the sunspots, temperatures are merely 3700 Kelvin (1) What does this indirect information about the Sun confirm?
A- The Sun has a structure similar to Earth's structure
B- Storms form on the surface of the Sun, similar to the atmosphere of Earth
C-The Sun's photosphere has properties of a solid, similar to the crust of Earth.
D-Convection occurs in parts of the Sun, similar to convection in the mantie of Earth
Answer:
I d k really but my educated guess is A- The Sun has a structure similar to Earth's structure * even tho the suns structure is completely gaseous is similar to earth w the layers ii don't know

- Which occurrence is the result of the cell cycle in unicellular organisms?
A. cell repair
B. cell growth
C. cell replacement
D. cell reproduction
Answer:
D
Explanation:
Cell reproduction is the result of the cell cycle in unicellular organisms. The correct option is D.
What is cell reproduction?Cells split to produce multiple cells with similar, if not identical, contents. This process is known as cellular reproduction.
Nuclear division during mitosis produces two somatic cells that are genetically identical to the parent cell and have the same genetic complement.
Asexual reproduction in prokaryotes takes the form of cell division in unicellular organisms.
When an organism splits in half, it creates two totally distinct daughter cells, a process known as binary fission. The daughter cells are identical to the parent cells genetically.
Most of the time, Paramecium reproduces asexually via budding, however in poor circumstances, they produce sexually.
Unicellular organisms have a variety of asexual reproduction strategies, including multiple fission, fragmentation, and budding.
Thus, the correct option is D.

If you wanted to study the effects of soil moisture and light intensity on the growth of soybeans and required a high ability to regulate these independent variables, what type of experiment would you choose?A. Laboratory experiment.
B. Field experiment.
C. Natural experiment.
D. Reference experiment.
Answer:
A
Explanation:
The correct answer would laboratory experiment.
In the laboratory, variables can be controlled as much as possible using relevant equipment unlike in natural habitats or field experiments. For example, the amount of water that each plant would receive can be measured using measuring cylinders and the time they are applied can also be fixed.
Field and natural experiments require that experimental procedures are carried out in the field under natural conditions. Consequently, variables such as the amount of moisture that gets into the soil or the amount of light a plant will receive will be extremely difficult to control. Precipitation time and the duration of light can also not be controlled.
The correct option is, therefore, A.

12 Which direction does blood flow in arteries?
Answer:
Like all fluids, blood flows from a high pressure area to a region with lower pressure.
Good luck!
Answer:
The arteries carry blood out of the heart and the veins carry it in. The flow of blood through the vessels and chambers of the heart is controlled by valves.
What might happen to the magma convection currents if there were no radiogenic heat produced in the core?
How would this affect life on Earth?
Plz help me
Answer:
If there were no radiogenic heat produced in the core, there would be no convection currents, and life on the Earth would not be possible.
Explanation:
The convection currents are the result of heating by temperature gradients. Differences in temperature and density produce these currents. Warm materials are lighter and can ascend, while cold materials are heavier and denser, so they tend to descend. These materials movements create a circular motion pattern known as convective currents. They occur in the atmosphere, in the water, and the Earth mantle. In the last case, while the hot material emerges from the bottom areas, the cold mantle sinks, creating a circular convection current. These play a significant role in fluids circulation and might be responsible for the movements of the lithospheric plates that are over the mantle. The temperature on the surface is much inferior that the mantle´s temperature, so the lithospheric pieces sink, creating a descendent current. Near the terrestrial core, the heat might reach up to 3,500ºC, and solid materials in these areas melt and fuse. When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents. The currents of ascending materials are known as thermal feathers or plumes.
Hot ascending material keeps the surface warm, making life possible. Also, radiogenic heat produced in the core is responsible for the electromagnetic field.
The electromagnetic field protects the Earth from many particles that come forward to the surface from space, specifically from the sun. The electromagnetic field also influences the atmosphere, keeping it in its place, necessary for life on Earth.
The plate´s movement produces earthquakes and volcanic activity. Both of them also necessary for many reasons, such as keeping fertile soils and producing necessary atmospheric gasses.
Through the years, the core losses heat, and eventually, it will become solid. When this happens, convective currents will stop because there will be no heat from the bottom to make them move. The electromagnetic field will disappear, and the atmosphere will be affected as well. The Earth surface will become cold. Mantle movement will stop, and there will be no earthquakes nor volcanic activities. Every living being on Earth will be affected by this fact. Life on Earth will not be possible.

Explanation:
if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?
Answer:
The earthworm will be 45 mm long in the picture
Explanation:
From the problem, we can take the original size of the earthworm to be 18mm.
Magnification can be obtained using the formula:
magnification = observed size/ original size.
Recall, we are given that the magnification is 2.5.
Hence, can evaluate the size in the picture to be
2.5 X 18mm = 45mm
