Answer: 125
Explanation:
Population size is the number of individuals in a population. First, the trapping yielded 80 mice that were marked. Two weeks later, 75 mice were trapped and 48 of them had the mark.
The formula used for this question is:
N=mn/x
N= population size in the 1-hectare field. m= number of individuals marked and released the first time. n= number of individuals captured the second time. x= number of marked individuals that are recaptured.
The experiment consist on a randome collect sample of individuals which are then marked and released. Next, take a sample again.
So, replacing the values we get:
N=(80)(75)/48
N=125 individuals.

que sistemas artificiales utiliza el hombre para recoger agua que sistemas existen de forma natural
Answer:
Haciendo almacenamiento y excavación en un área grande, mientras que los estanques son los sistemas utilizados para recolectar agua.
Explicación:
El sistema artificial que el hombre usa para recolectar agua es la construcción de un gran almacenamiento de concreto y la excavación de un gran terreno que recolecta agua de lluvia y puede ser utilizado por la gente para su uso diario, mientras que por otro lado, los estanques son el sistema natural donde el agua del la lluvia se acumula naturalmente. Esta agua es utilizada por la población que vive alrededor de ese estanque. Ambos sistemas proporcionan agua para el uso diario, como lavar, beber y cocinar, etc.

During his voyage on the HMS Beagle, Darwin observed the
beaks and behavior of finches. These finches were similar
in some ways to the single finch species that existed on
the mainland of South America. On the Galápagos Islands,
however, there were 13 different species, each with
different beaks and different diets. Later, Darwin
hypothesized that natural selection could explain the
differences in the finch species. Many years later,
Rosemary and Peter Grant of Princeton University began to
test Darwin's hypothesis.
Scientists have recently developed a hypothesis based on
evolutionary concepts and the Grants' work. First, finches
from South America arrived on one of the islands. Then,
the finches that arrived on the island had to survive in a
new environment. The plants on the island were different
from the plants on the mainland. As a result, the
population on the island evolved differently from the
population on the mainland.
Later, a few finches from the island may have flown to
another island and begun the speciation process again.
This process may have been repeated many times. Now
there are 13 distinct species.

which one is it I am confused A,B,C or D
Answer:
I think option B is right answer
Answer:
B) Image 1 -> Image 3 -> Image 4 -> Image 2
Explanation:
The pictures of the ecosystems are needed to be put into the simplest -> complex order.
Image 1 could be the simplest as it only has one organism.
Image 3 would be the next simplest as it has only a group of the same organism.
Image 4 would come next as it has aqua life and surroundings but the same fishes!
Image 2 would be the most complex, as it has various biodiversity and surroundings!
The order would go as Image 1 -> Image 3 -> Image 4 -> Image 2.

give a reason why eggs shell is porous
Answer:
if it's porous it must absorb stuff
Explanation:
like a napkin
Answer:
Explanation:Directly under the chicken egg's shell are two membranes. When the eggs are laid by the mother they are warmer than the air, and as they cool the material inside the egg shrinks a little bit. ... The tiny pores in the shell allow the carbon dioxide to escape and fresh air to get in.
Part C When a material is heated, the change in temperature depends on the kind of material and its mass. Different objects can absorb and release different amounts of energy when heated and cooled. This property is called heat capacity. How might scientists apply this property to design something useful in the real world? Give one or two examples.
Answer:
Not really sure about this question but what I think is,
So for example, metal..Metal has a very low specific heat capacity, but we use it pretty much in all our lifetime right? Things that have low heat capacity have very high capacity if that makes sense. Things like water and oil, they take more energy to get heat up or get hot. Its funny because its what makes our planet survivable. 70% of our planet is of course water and radiation (light and heat) from the sun strikes 70% of water. Meaning its not heating anything up so quickly. Hope this somewhat helps you out and gives you an idea on what the question is talking about :) Enjoy!

What happens to water molecules during the boiling process
Which of the following processes causes
sinkholes to form?
A. erosion of sediment by runoff
B. deposition of sediment by a river
C. deposition of calcite by groundwater
D. erosion of limestone by groundwater
Answer:
A. erosion of sediment by runoff
Explanation:
The formation of sinkholes involves natural processes of erosion or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion.
Answer:
A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. ... Water collects in these collapsed sections, forming sinkholes. Sinkholes also form when the roofs of caves collapse.
