Civil engineers want to determine whether the porosity of surface soil affects aquifer recharge rates

Answers


Aquifer recharge is water that moves from the land surface or unsaturated zone into the saturated zone. Quantitative estimation of recharge rate contributes to the understanding of large-scale hydrologic processes. It is important for evaluating the sustainability of groundwater supplies, though it does not equate with a sustainable rate of extraction. Where contamination of an aquifer is a concern, estimating the recharge rate is a first step toward predicting solute transport to the aquifer. Recharge may cause a short- or long-term rise of the water table. Artificial drainage, e.g., with horizontal porous pipes buried at a chosen depth, is sometimes used to maintain a minimal thickness of vadose zone for agricultural or other purposes.
Recharge rates vary considerably in time and space. Recharge often occurs episodically in response to storms and other short-term, high-intensity inputs. For a given amount of infiltration, temporal concentration enhances recharge because it entails shorter residence times for water in the portions of the soil from which evapotranspiration takes place. Similarly, a larger fraction will become recharge if it is concentrated in narrow channels such as fingers or macropores, not only because this tends to hasten its passage through the unsaturated zone, but also because the water then occupies less of the volume of soil from which evapotranspiration takes place.

Name two types of proteins that regulate the cell cycle. How do these proteins work?

Answers

Answer:

Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.

Explanation:

I hope this helps :)

The two types of proteins that regulate the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs). These two groups of proteins are responsible for the progress of the cell through various checkpoints.

What are Proteins?

Proteins are made up of hundreds or thousands of smaller units called Amino acids. They are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.

Cyclins regulate the cell cycle only when they are bound to Cdks and become fully active. The Cdk/cyclin complex must be phosphorylated, which further initiates other proteins to be phosphorylated that advances the cell cycle.

Retinoblastoma (Rb), is another group of tumor-suppressor proteins that regulates the cell cycle by monitoring the cell size.

Therefore, there are two types of proteins that regulate the process of the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs).

What scientist used radioactive bacteriophages to prove DNA is the
hereditary material passed from one generation to the next?

Answers

Answer:

Alfred Hershey and Martha Chase

Explanation:

In 1952 Alfred Hershey and Martha Chase were working with bacteriophages or phages, which are viruses that infect bacteria. They knew that a phage had an outer shell of protein and an inner core of DNA. In addition, from the electron microscope observations, they also knew that during infection the virus attacks the bacterium by its tails and introduces its genetic material into the bacterium to multiply using its metabolic machinery. They radioactively labeled two sets of phages: one with 32P (which marks only DNA) and another with 35S (which marks only proteins). In two parallel experiments, they infected bacteria with viruses marked on their DNA and with viruses marked on their proteins. The cultures were shaken with a mixer to separate the virus particles from the bacterial coatings. They then performed a centrifugation to separate the phages from the bacteria, so that the larger and heavier bacteria remain in the pellet, while the phages remain in the supernatant. They found that the radioactivity of 35S appeared in the supernatant while that of 32P appeared in the sediment, from which new radioactively labeled virus particles appeared, demonstrating that DNA was the genetic material.

What are prokaryotes?

The organisms known as prokaryotes lack a nucleus and other organelles in their cells. There are two distinct groups of prokaryotes: the archaea and bacteria, both of which are thought to have evolved along distinct evolutionary lines.

Prokaryotic organisms or prokaryotes are organisms that lack a true nucleus and membrane-bound cell organelles. Mycoplasma, cyanobacteria, and bacteria are all examples of prokaryotes.

A prokaryotic cell carries out every one of the fundamental roles that an ordinary cell performs. Reproduction, respiration, digestion, and other biological processes are among their capabilities.

The figure C represents Five kingdom classification.

What is Five kingdom classification?

The system of biological kingdoms is the way in which science classifies living things according to their ancestry over the course of evolution.

This means that all the species that make up these five large groups - some recent theories split them further into six or even seven - have common ancestors and therefore share some of their genes and belong to the same family tree.

As well as the kingdoms of living things there are other taxonomic categories within the same classification system such as, for instance, domain, phylum, class, order, family, genus and species.

Therefore, The figure C represents Five kingdom classification.

After the destruction of forest, new plants grow on that land, this type of phenomenon  is called ecological succession.

but light can get in when the tank is not covered.
The light for the tank has been on all day, and Kai measured the carbon
in the air and found that it is decreasing. How is carbon moving between
the air and the living things in
the tank? What is happening to the amount
of carbon in living things?
Just tell me those two questions plz help me I will give you my points I swear plz help me I beg you

Answers

Simple answer is that the plants are conducting more photosynthesis than all the organisms in the tank are carrying out cellular respiration. This would be why the carbon (CO2) levels are decreasing. They are being incorporated into the plant as sugars.

The amount of carbon is captured by plants to perform photosynthesis as a light for the tank has been on all day and prepare their own food. The product of photosynthesis is consumed by other organisms to perform cellular respiration.

What are the components of photosynthesis?

The components of photosynthesis may include carbon dioxide, water, and sunlight as raw materials to convert into glucose (a food molecule).

The amount of carbon will not remain the same for the entire time in the living organism. The cycling of carbon is processed synergistically during photosynthesis and cellular respiration.

Living things in the tank respire out carbon, which is taken up by plants for photosynthesis, a product of photosynthesis are the reactants for cellular respiration. In this way, carbon delocalized among the living entities.

Therefore, it is well described above.
