Explanation:
How will the changes to the hydrosphere affect the atmosphere, geosphere, and biosphere?
Answer:
The hydrosphere allows the geosphere to be eroded by flowing water and precipitation. The biosphere breaks down geospheric rock (plant roots), but geospheric minerals feed the plants when it comes to soil. Geosphere produces, kills and preserves several biosphere locations.
Explanation:
Explain the relationship between chlorophyll absorption and wavelength.
Answer:
The color of the pigment comes from the wavelengths of light that are reflected, or in other words, those wavelengths not absorbed. Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. This is why plants appear green to us.

In order to protect aquifers near landfills, material is placed under the soil to prevent pollution. Which property must the protective material possess?
Answer:
The correct answer is - low permeability.
Explanation:
Low permeability does not allow the pollutant to leak or diffuse from the pollutant to the ocean or aquifers near landfills. The permeability of protective material should be lower as they lead the pollutants to the soil, and environment such as contents of battery, toxic plastic, and other pollutant toxins to the soil and aquifers.
Thus, the correct answer is - low permeability.

The total mass of the
___has to be the
same as the mass of
the products.
Answer:
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.
Explanation:
Shield volcanoes are ___ stratovolcanoes
1. Equally explosive as
2. more explosive than
3.less explosive than
Answer:
Less explosive than
Explanation:
When hydrogen nuclei are fused together to form a helium nucleus, the mass of the product is 0.7% less than the mass of
the reactants. If 1 gram (1 x 10-3 kg) of protons were completely fused into helium nuclei, the mass of the helium nuclei
produced would be 6.8 x 10-6 kg less than the mass of the protons.
Using the equation E = mc2, calculate how many joules of energy would be produced by converting 6.8 x 10-6 kg of matter
into energy in this fusion reaction. Use c = 3 x 108 m/s.
E = 6.05 x 1011 kg x m²/s2
E = 6.10 x 1011 kg x m2/s2
E = 6.12 * 1011 kg x m2/52
E = 6.25 x 1011 kg * m/s2
E = 6.30 x 1011 kg m/s2
When the atmosphere is warmed by the sun the changes in air pressure and air temperature result in:
Answer: Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure. But, air pressure also affects temperature - the more those molecules bump into each other, the more heat they generate.

which of the following would be an ongoing way to collect evidence,even until the trial starts?
notes
photograph
video
drawings
For an ongoing way to collect the evidence until the trial starts video making will be an appropriate procedure.
Scene of crime is a place where potential evidences related to prove crime can be found. Video making is an excellent approach to capture the entire scene of crime. It will help in recording all the details, sequence of events that could have taken place, and details of all evidences in a single shot. Video making can be useful for reconstruction of crime event. Video making is also appropriate to record the activities of the criminal till he or she reaches court for the trial. Note making can sometimes become presumptive related to case, photograph can give the details of the evidences but cannot relate them with the entire scene of crime, drawing can be done in the form of sketching of the scene of crime using scalar measure to establish the location of evidence to the point.Learn more about evidence:

Explanation:
Many farms and ranches use reservoirs, like the one shown here, to collect and store rainwater. Reservoirs ensure there is enough water for crops and animals. Describe the type of soil that would be best for lining a reservoir.
Answer: Water harvesting (WH) and small-storage technologies are key water-related ... technologies can also help provide water for domestic use, livestock, fodder and tree production, ... WH is the collection of rainfall runoff for subsequent beneficial use. ... of rainfall entering soil storage, where it can later be used directly by plants.
Explanation:
The type of soil that would be best for lining a reservoir is Bentonite Clay.
What is Bentonite Clay?Montmorillonite, which can either be Na-montmorillonite or Ca-montmorillonite, makes up the majority of bentonite, an absorbent swelling clay. Compared to Ca-montmorillonite, Na-montmorillonite can swell much more.
A very fine clay soil is bentonite clay. More water is absorbed by it than by other kinds of clay. Bentonite should be compressed after being combined with coarse material.
The clay then swells up and becomes impenetrable when water is added to the reservoir.
Reservoirs, like this one, are frequently used by farms and ranches to catch and store rainfall.
Reservoirs guarantee that there is enough water for both animals and crops. Bentonite Clay is the best kind of soil to use for reservoir lining.
Thus, the answer is Bentonite Clay.

Oxygen is very essential for the survival of organisms. The component of blood enable oxygen from the environment to move from the lungs to cells of the body are red blood cells.
What are red blood cells?Red blood cells, also known as red blood corpuscles, haematids, erythroid cells, and erythrocytes.
These are the most prevalent form of cells of blood and the vertebrate's primary mechanism of supplying oxygen to body tissues through blood flow with the help of hemoglobin.
It has hemoglobin that helps for the transport of oxygen from lungs to cells of body.

Answer:

Explanation:
DNA replication
The nucleic acid sequences are complementary and parallel, but they go in opposite directions, hence the antiparallel designation. The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way.
In a species of bird, the allele for the striped trait is recessive to the allele for the speckled trait. Suppose that a coastal bird population has a striped phenotype frequency of and an inland population has a striped phenotype frequency of The two populations are isolated and in Hardy–Weinberg equilibrium. Let represent the allele frequency of the coastal population and represent the allele frequency of the inland population. Calculate the allele frequency for the striped allele for each population. Round your answers to the nearest hundredth.
Answer:
The answer is "0.42"
Explanation:
Please find the complete question in the attached file.
Coastal community striped allele intensity [tex]= q = 0.62[/tex]
Landlocked community, strip intensity allele[tex]=q'=0.40[/tex]
Its eliminated allele frequency for movement [tex]= q"=0.42 \ in \ indoors[/tex]community And now in the sturdy vineyard optimum communities, genotype frequency of stripped characteristic (heterozygous device) in coasts[tex]=q_2=0.39[/tex]
Heritable (striped) allele frecency:
[tex]\to q=\sqrt{q_2}[/tex]
[tex]=\sqrt{0.39} \\\\ =0.624 \\\\ =0.62[/tex]
(round up to the closest cent) is therefore the only frequency of coastal people.
The genome of pulling function in host population[tex]= q'_2=0.16[/tex] Heterozygous feature regularly.
Therefore the inland community rate of recessed (striped), allele rate:
[tex]\to q'= \sqrt{q'_{2}}= \sqrt{0.16}=0.40[/tex]
Following migration;
Its percentage of coastal migrants:
[tex]m=10\% \\\\[/tex]
[tex]= \frac{10}{100} \\\\= 0.1[/tex]
Coastal population Non-immigrant percentage of coastal residents:
[tex]=1- m\\\\=1-0.1\\\\ =0.9[/tex]
Stripping coastal community of allele rate after immigration:
[tex](q")=\text{(stripping of migrant only freq)}\times (m)+\text{(stripping allele baud rate for non-immigrants)} \times ( 1-m)[/tex]
[tex]= [q \times m]+[[q' \times(1-m)]\\\\=(0.62 \times 0.1)+(0.40 \times 0.9)\\\\=0.062+ 0.36\\\\=0.422\\\\=0.42[/tex]
