The fact that marsupials are not as diverse in South America as they are in Australia would be classified as biogeographical evidence for evolution.
Biogeographical evidence focuses on the distribution of species across different geographical regions and how this distribution is influenced by factors such as geological events, climate change, and habitat differences. In the case of marsupials, their diversity in Australia is attributed to the unique evolutionary path they followed after the continent became isolated from the rest of the world. This isolation allowed marsupials to adapt and evolve in response to Australia's distinct environmental conditions, resulting in a wide range of species with unique adaptations.
Conversely, South America's marsupial diversity is less pronounced due to factors such as competition with placental mammals, which are more dominant in the region, and differences in available habitats. This limited diversity also supports the concept of evolution, as it demonstrates how varying selective pressures in different geographical areas can lead to different levels of species diversity and unique evolutionary paths. Overall, the contrasting marsupial diversity between Australia and South America serves as biogeographical evidence for evolution, highlighting the role that geography and environmental factors play in shaping the development and distribution of species.

Can a man with type AB blood be the biological father of a child with type O blood?
Yes, it is possible for a man with type AB blood to be the biological father of a child with type O blood. This is because blood type is determined by genes that are inherited from both parents.
Type O blood is determined by the absence of A and B antigens on the surface of red blood cells. So, if the mother of the child has type O blood, the child will also have type O blood.
However, If the mother of the child has blood type A or B, the child will inherit one of the antigens from the mother and the father can contribute the gene for O blood, in this case, the child will have type A or B blood.
A man with type AB blood carries both A and B antigens, but also carries the gene for O type, so it's possible for him to pass the O gene to the child.
Blood type inheritance is a complex process involving multiple genes, so it's always recommended to confirm paternity through a DNA test.

how low-cost water leads to waste of fresh water in irrigation, industries, and homes?
Up to 50% of the groundwater we use outside is lost to the elements including wind, evaporation, and runoff brought on by ineffective irrigation techniques, businesses, and infrastructure.
How does evaporation explain itself?A liquid transforms into a gas during evaporation. It is simple to picture when puddles of rain "vanish" on a hot day and when wet clothing dries in the sun. In these instances, the sea phase is draining into a gas known as water vapor rather than really dissipating. Global evaporation takes place.
Why is the evaporation process so crucial?Wind panels, or heat from the sun, is what causes the evaporation process to occur. It takes on moisture from garden soil as well as the biggest lakes and oceans. As the water is uncovered to the sun's heat, its level will drop.

what are the limitations to earths mantle?
Answer:
The scale of mantle heterogeneities has been debated ever since the first observations of isotopic variations along mid-oceanic ridges1,2. Subsequent studies on lead and strontium isotopic variations along the Mid-Atlantic Ridge3–5 have shown that these isotopic compositions may vary with a major wavelength of ∼100–1,000 km. The immediate question is that of the scale (if any?) at which one may consider a piece of suboceanic mantle under a ridge to be homogeneous. We have studied two segments of oceanic ridges at the scale of a few kilometres. One of these portions of oceanic ridge, the CYAMEX zone in East Pacific Rise is typical, with a strongly ‘depleted’ chemistry. The other one, with an ‘intermediate’ chemistry, is the FAMOUS zone of the Mid-Atlantic Ridge. Our results show isotopic homogeneity for both zones even though small Pb variations persist on a small scale.
Humans have not been able to travel more than a few miles beneath Earth's surface because of the intense heat and pressure. For the same reasons, humans have not been able to travel into the mantle. Temperatures in the mantle range from 1600 degrees Fahrenheit at the top to 4000 degrees Fahrenheit near the bottom.

Braking just short of lockup is known as _____.
Braking just short of lockup is known as ABS (Anti-lock Brake System) braking.
Anti-lock Brake System (ABS) braking is a safety feature that is designed to prevent the wheels of a vehicle from locking up during heavy braking. This is known as "lockup" or "wheel lock." In a traditional braking system, when the driver applies the brakes hard, the wheels can stop rotating, which can cause the vehicle to skid or lose control. With ABS, sensors on the wheels detect when a wheel is about to lock up and automatically pulse the brakes to prevent it from happening. This allows the driver to maintain steering control and avoid skidding, even during hard braking, which helps to shorten the stopping distance and reduce the risk of a crash.

a 6.50g piece of substance B was rolled out into a thin sheet measuring 24.0 cm x 18.0 cm. calculate the volume and the density of the sheet of metal. show work use units
The volume and the density of the sheet of metal can not be calculated because the value for thickness is unknown.
Calculating the volume of the sheet of metal:m = 6.50g
w = 24.0 cm
L = 18.0 cm
We need to determine its thickness. Since we don't know the thickness, we can calculate it by using the density formula:
Density = Mass / Volume
ρ = m/v
making Volume, V the formula :
Volume = Mass / Density
We know the mass of the substance (6.50g) and we can assume that the density is constant throughout the sheet.
We can assume that the density of the sheet of metal is the same as the density of substance B.
So, the volume of the sheet of metal is:
Volume = 6.50g
Density
= (6.50g)
(Density of substance B)
We can calculate the area of the sheet by using the formula:
Area = length x width
Area = 24.0cm x 18.0cm
Area = 432cm²
And the thickness of the sheet is:
Volume = (6.50g)* 432cm²
Area (Density of substance B)
Now we can calculate the density of the sheet by using the formula:
Density = Mass
Volume
Density = 6.50g
(432cm² x thickness)
Hence, the density of the sheet of metal is:
Density = 6.50g
(432cm² x thickness) g/cm³

how does the use of fertilizer affect the nitrogen cycle
Answer:
When farmers harvest crops, a lot of the plant material is also removed. Little is left to decay and return nitrogen to the soil. If the soil stays this way, it will start producing fewer crops. Fertilizer contains the nitrogen compounds that are essential for plant growth. It can be used to replace the nitrogen in the soil to ensure the growth of healthy crops.
Explanation:
sample res.
The use of fertilizer can increase the amount of nitrogen in soil and water, leading to eutrophication and harmful algal blooms.
What is nitrogen cycle?Fertilizers are commonly used in agriculture to supplement the soil with nutrients such as nitrogen, phosphorus, and potassium. When nitrogen-rich fertilizers are applied to crops, the excess nitrogen can affect the nitrogen cycle in several ways.
Firstly, excess nitrogen can be leached from the soil and enter nearby water bodies, leading to eutrophication. This process involves the growth of excessive algae and aquatic plant life, which can deplete the water's oxygen levels and harm fish and other aquatic organisms.
Secondly, excess nitrogen can lead to soil acidification, reducing the soil's fertility and inhibiting plant growth. This can result in the need for even more fertilizer to maintain crop yields, exacerbating the issue.
Lastly, excess nitrogen can increase nitrous oxide emissions, a potent greenhouse gas that contributes to climate change.

How does a root of a plant that lacks chloroplast get energy?
A root of a plant that lacks chloroplast gets energy through the storage of food. Plant cells that do not have chloroplasts are plants that don't create their own food. These plants usually have stored food.
How do plants survive without chloroplast?Without chloroplasts, plants would not be able to get their energy from the sun and would cease to survive, leaving us without food. On the other hand, without mitochondria, animals would be lacking in cellular energy and would also fail to survive.
In respiration, root cells burn glucose that's been transported from the leaves. Glucose is transformed into cellular energy (called adenosine triphosphate or ATP) that's used to drive metabolic processes, mainly water, and nutrient uptake.
