Answer:
The type of erosion described in the question is called Water Erosion.
Explanation:
Note that the erosion is caused by winter and spring rains.
Water Erosion can happen when raindrops disintegrate the aggregates of the topsoil. The fragments collect into the soil pores and create a coagulating action which makes it difficult for the water to penetrate the soil. The rainwater having increasingly accumulated on the surface flows off along with the topsoil.
This type of erosion can be further aggravated if:
the rainfall is very heavy;the terrain has a steep gradient thus increasing the velocity of runoffthe soil type has a lower capacity to erosionCheers!
Scientists want to track the wind speeds and precipitation for a hurricane that will affect the entire East Coast of the United States. Which weather equipment would be best to measure the impact of the storm for this entire region? A. an anemometer B. a rain gauge C. Doppler Radar D. global positioning system (GPS)
Answer:
A anemometer an instrument for measuring the speed of the wind, or of any current of gas.
GPS is to see where you on on the earth so this is a no.
rain gauge only shows the amount of rain so this is a no
Doppler radar determine's the location and velocity of a storm, clouds, precipitation. So therefore, this is your answer.

Arrange the sentences in order to describe how oxygen from air is transported to the cells in the kidneys.
Answer:
The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.

Find the weight of a pine tree that has a circumference of 14 inches and a height of 120 feet. Use the equation: W = b0 + b1(D2H)
Answer:
The answer is below
Explanation:
The weight of trees is calculated using the equation:
[tex]W=b_o+b_1(D^2H)[/tex]
W is the tree weight in tons, D is the diameter of the tree in inches, H is the height of the tree in feet and [tex]b_o \ and\ b_1[/tex] are constants.
The circumference is given by:
Circumference = 2πr
Where r is the radius and 2r is the diameter
Therefore:
14 = 2(22/7)× r
14 = (22/7)×2r
2r= 14 × 7 / 22
Diameter = 2r = 4.455 inches
[tex]W=b_o+b_1(4.45^2*120)\\W = b_o+2381.643b_1\\Let\ us\ assume\ b_o = -35,b_1=1.9.\\Therefore\\W = -35+2381.643(1.9)\\W=4490 \ tons[/tex]

Explanation:
When you centrifuge the DNA isolated from the bacteria, the DNA separates into two classes. One class of labeled DNA includes very large molecules (thousands or even millions of nucleotides long), and the other includes short stretches of DNA (several hundred to a few thousand nucleotides in length). Which two classes of DNA do these different samples represent
Answer:
Leading strand and Okazaki fragments
Explanation:
The two classes of DNA that the different samples represent include the leading strand and the Okazaki fragments.
The large molecules DNA with thousands/millions of nucleotides constitutes the leading strand of the DNA while the short stretches of DNA with just a few thousand nucleotides in light constitute the Okazaki fragments.
This is because, during replication, the leading strands of DNAs are usually synthesized in a continuous manner and end up forming a long, continuous daughter strand while the lagging strands are usually synthesized in short, discontinuous fragments known as the Okazaki fragments.
The continuous/discontinuous replication of the leading/lagging strands of the DNA is due to the characteristics of the enzyme responsible for adding bases to the growing daughter strands. The DNA polymerase enzyme can only add nucleotides in the 5' to ' direction.

Imagine an invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have:____. a. a cyclic variation depending upon when the animal drinks. b. regular variations that range from large to small. c. slight fluctuations that are kept within a narrow range. d. a cyclic variation opposite that of the surrounding water.
Answer: Option C.
slight fluctuations that are kept within a narrow range.
Explanation:
An invertebrate that lives in an estuary where salinity varies cyclically with the tides. If this individual is able to adjust the salt concentration of its body fluids, its salt concentration will have slight fluctuations that are kept within a narrow range so has to maintain homeostasis and prevent the cells of the the invertebrate from not shrinking which can be due to the salt solution (Hypertonic).
Estuary is an area of water or shorelines where river meet the ocean. It normal do have concentration of salts. Organisms that live in estuaries must be able to adapt to their dynamic environments, wich is due to variations in water chemistry includes salinity, as well as physical changes like the rise and fall of tides.

What is chromosomes?Write in brief about the structure of a chromosome.must include all points with explanations
Answer:
Please find the detailed explanation below
Explanation:
A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.
Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.
Which ecosystem service would suffer from the opening of a mineral mine along a small mountain range?
A. Cultural
B. Provisioning
C. Regulating
D. Supporting
Answer:
D. Supporting
Explanation:
Ecosystem services include provisioning, regulating, culture and supporting services.
Opening of a mineral mine along a small mountain range will affect the supporting services of ecosystem because supporting services deals with soil formation, provision of habitat and nutrition cycle.
Opening of mineral mine will destroy the tosoil, landscape, forests and wildlife of mountain area which affect the supporting services such as habitat and soil formation.
Hence, the correct answer is "D. supporting".

c. reach a conclusion
d. record observations and measurements
Answer:
D
Explanation:
While performing an experiment, it is important to record observations and measurements, as in Option d. Option d is correct regarding the facts of the experiments, while the others are wrong.
What is an experiment?The experiment is carried out to observe the hypothesis, and in this process, a control set-up is taken whose value or result is already known, and the variables are taken and compared with the control. The controls set should never change in the experiment because the variables are tested with reference to them, and the measurements and observations of the experiment should be taken into consideration to prove the hypothesis. All the variables should not be tested at once because if this is done, it would introduce error into the experiment, and not all the experiments are done to get the conclusion.
Hence, while performing an experiment, it is important to record observations and measurements, as in Option d.

Proteins in the cell membrane have many functions. Which type of protein would be used for cell recognition and as a receptor? A. Pore proteins B. Endoplasmic proteins C. Glycoproteins D. Integral proteins
Answer:
C. glycoproteins
Explanation:
Glycoproteins are proteins containing glycans (oligosaccharide carbohydrates) attached to amino acid side chains. These oligosaccharides are attached to the amino acid chain by a posttranslational modification referred to as glycosylation, a modification generally found in extracellular regions. Glycosylation refers to the chemical reaction in which a glycosyl donor (i.e., the carbohydrate) is attached to a functional group in the protein. The glycosylation sites play distinct functional roles for both cell interactions and cell recognition. Moreover, glycosylation sites are also essential for substrate recognition by an enzyme. For example, secreted cytokines are glycosylated, which is required for their binding to receptors.
What results if a broken chromosomal fragment becomes reattached as an extra segment to a sister or non-sister chromatid? A Duplication B Inversion C Polyploidy D Nondisjunction
Answer:
The correct answer is option A "Duplication".
Explanation:
Chromosomal duplication is defined as a type of rearrangement of genetic material at which extra copies of a DNA fragment are created. In this case if a broken chromosomal fragment becomes reattached, this fragment will represent an extra copy, and therefore the resultant genetic material is considered a chromosomal duplication.
The Peppered moth is white with black spots, which helps it blend in with the bark on beech trees. The burning of coal in Great Britain caused many beech trees to become black with soot. Over time, the Peppered moth became all black in order to blend in with the new bark color. What type of example is this? homeostasis metabolism organization adaptation
Answer:
adaptation
Explanation:
Adaptation in Biology refers to the process whereby an organism adjust to its natural environment in order to increase its chance of survival or in other words, the organism becomes better suited to its natural habitat by possession of some adaptive features.
In this example, a white peppered moth with black spots initially possess these color combination in order to blend to its natural environment, which is the bark on beech trees. However, due to the burning of coal in Great Britain which caused many of the beech trees to be black, the peppered moths had to ADAPT to this change in environmental color by becoming all black in order to blend in with the new bark color.
Therefore, this is an example of ADAPTATION.

The goal of disinfection of public water supplies is the elimination of the pathogens that are responsible for waterborne diseases. The transmission of diseases such as typhoid and paratyphoid fevers, cholera, salmonellosis, and shigellosis can be controlled with treatments that substantially reduce the total number of viable microorganisms in the water.
While the concentration of organisms in drinking water after effective disinfection may be exceedingly small, sterilization (i.e., killing all the microbes present) is not attempted. Sterilization is not only impractical, it cannot be maintained in the distribution system. Assessment of the reduction in microbes that is sufficient to protect against the transmission of pathogens in water is discussed below.
Chlorination is the most widely used method for disinfecting water supplies in the United States. The near universal adoption of this method can be attributed to its convenience and to its highly satisfactory performance as a disinfectant, which has been established by decades of use. It has been so successful that freedom from epidemics of waterborne diseases is now virtually taken for granted. As stated in Drinking Water and Health (National Academy of Sciences, 1977), "chlorination is the standard of disinfection against which others are compared."
However, the discovery that chlorination can result in the formation of trihalomethanes (THM's) and other halogenated hydrocarbons has prompted the reexamination of available disinfection methodology to determine alternative agents or procedures (Morris, 1975).
The method of choice for disinfecting water for human consumption depends on a variety of factors (Symons et al., 1977). These include:
its efficacy against waterborne pathogens (bacteria, viruses, protozoa, and helminths);
the accuracy with which the process can be monitored and controlled;
its ability to produce a residual that provides an added measure of protection against possible posttreatment contamination resulting from faults in the distribution system;
the aesthetic quality of the treated water; and
the availability of the technology for the adoption of the method on the scale that is required for public water supplies.
Economic factors will also play a part in the final decision; however, this study is confined to a discussion of the five factors listed above as they apply to various disinfectants.
The propensity of various disinfection methods to produce by-products having effects on health (other than those relating to the control of infectious diseases) and the possibility of eliminating or avoiding these undesirable by-products are also important factors to be weighed when making the final decisions about overall suitability of methods to disinfect drinking water. The subcommittee has not attempted to deal with these problems since the chemistry of disinfectants in water and the toxicology of expected by-products have been studied by other subcommittees of the Safe Drinking Water Committee, whose reports appear in Chapter III of this volume (Chemistry) and Chapter IV (Toxicity) of Drinking Water and Health, Vol. 3.
Organization of the Study
The general considerations noted in the immediately following material should be borne in mind when considering each method of disinfection. Available information on the obvious major candidates for drinking water disinfection—chlorine, ozone, chlorine dioxide, iodine, and bromine—is then evaluated for each method individually in the following sections. Other less obvious possibilities are also examined to see if they have been overlooked unjustly in previous studies or if it might be profitable to conduct further experimentation on them. Disinfection by chloramines is dealt with in parallel with that effected by chlorine because of the close relationship the former has to chlorine disinfection under conditions that might normally be encountered in drinking water treatment.
