how does water get into the aquifer? i will mark branliest if you answer correct!

Answers

Answer:

Water gets into an aquifer from the land surface

Answer:

Water gets into an aquifer from the land surface. Typically, precipitation falling onto the Earth's surface soaks into the ground and flows down to the water table.

Explanation:

Most wells do not get their water from underground rivers, but instead get the water from aquifers. Aquifers are layers of rock and soil with water flowing through their small pores. ... New water, such as from rain or melting snow, drips down into the ground through the pores and cracks in the rocks and soil. Groundwater is transported through aquifers because of two main reasons: gravity and pressure. In unconfined aquifers, which we concentrate on because they are more likely to be contaminated, water always flows from high points to low points because of gravity.

Which of these changes to fuel consumption would lessen human
impacts on global climate?
Select one:

A) Decreasing research of all wind or water-based electricity generation technologies
B) Switching from coal to natural gas or nuclear energy to generate electricity
C) Increasing electricity production from coal
D) Banning any form of carbon emissions trading programs

Answers

The answer is C I believe

Switching from coal to natural gas or nuclear energy to generate electricity will lessen human impacts on the global climate.

What is climate change?

It is the changes to climate brought about by anthropological emission of greenhouse gases.

Greenhouse gases are emitted from human actions such as the burning of coal, removal and burning of forest layers, etc.

Thus, in order to lower human impacts on climate, replacing activities such as the burning of coal with clean technology such as nuclear energy to generate electricity would go a long way.

Methylmercury biomagnifies in an ecosystem, meaning its concentration __________ as it moves through each higher trophic level.
A. equalizes
B.does not change
C. decreases
D. increases

Answers

Answer:

D - Methyl Mercury Increases

Explanation:

The word Biomagnification has a simple explanation:

To magnify is to make bigger, meaning that the substance in question is becoming more abundant.

The "bio" part of this word is referring to the fact that it is a biological substance you are dealing with.

Question: "Methylmercury biomagnifies in an ecosystem, meaning its concentration __________ as it moves through each higher trophic level."

Answer: "The concentration of the methylmercury increases as it moves through each higher trophic level. Hence, the methylmercury biomagnifies in the ecosystem. So, based on the options given prior to the question above, Option D) increases would be your best bet."

For this cell division, you can see that 4 daughter cells are made that have half the genetic information as the original. What type of cell division is this?

a) Diffusion
b) Mitosis
c) Meiosis
d) Photosynthesis​

Answers

Answer:

The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).

Explanation:

Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.

In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.

The other options are not correct because:

    a) Diffusion: it is a passive trans-membrane transport mechanism.

    b) Mitosis: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.

    d) Photosynthesis: is the mechanism by which plants obtain energy and nutrients, from solar energy.

after the process of mitosis, if the resulting cells have 48 chromosomes, how many did the parent cell have?

a. 48

Answer:

Mass wasting has drastic effects on human and animals life in the form of landsliding , earthquakes . Deposition is the pres in which sediments , rocks and soil are added land mass . A positive effect of deposition is that it creates new land . And negative effect is it takes away new lands .

The five (5) evidence of exogenic processes on Earth's surface include the following:

1. Weathering.

2. Stripping.

3. Erosion.

4. Mass wasting.

5. Deposition.

Exogenic processes can be defined as the processes that occur at or near the surface of planet Earth due to the action (influence) of exogenic forces or geomorphic agents.

The five (5) evidence of exogenic processes on Earth's surface include the following:

1. Weathering: the removal of various minerals from rocks causes depletion in oil and gas reserves that may be available for human consumption.

2. Stripping: it involves the removal of essential chemical elements and  components from precious stones and landform such as a mountain.

3. Erosion: this causes flooding and washing away of various soil nutrients and as such affects agriculture.

4. Mass wasting: it moves rock debris, soil nutrients, and regolith downward, which are substances that are useful for certain human activities such as during mining.

5. Deposition: it is a consequence of erosion and it result in the laying down of sediment on a landform or landmass.

This sometimes make the foundation of buildings stronger to withstand stress.
