Answer: soil type
Explanation:
All of the following affect groundwater contamination except Soil type.
What is Soil type?In soil science, a soil type is a taxonomic unit. A distinctive soil type is made up of all soils that have a certain set of well-defined features in common.
The phrase "soil type" refers to the study of soil classification, which is concerned with the orderly classification of soils. Every soil on the planet is a particular soil type.
The majority of soil types in hierarchical soil classification schemes are in the higher or intermediate level. Typically, a soil type can be further broken down into subtypes, and in many systems, multiple soil types can be joined to form higher category entities.
Therefore, All of the following affect groundwater contamination except Soil type.

Understanding Dose vs Exposure
John works applying pesticide X to agricultural fields. He spent the morning cleaning out a tank that had contained concentrated pesticide X. The tank was large and he was standing in water all morning (4 hours) power washing the tank. Human skin is a wonderful barrier to entry of compounds as long as it is dry and intact, but wet wrinkly skin can absorb toxins. About 5% of pesticide X absorbs into wet skin and John was in contact with water that had a total of 32 g of the pesticide in it.
After the morning is over, John has lunch but does not wash his hands; he has 2 g of the pesticide on his hands. Pesticide X has about 90% absorption from an oral dose.
Finally, John works in the field in the afternoon a crop plane flies over dusting the crops with pesticide X, the air he breathes in has a total of 5 grams of the compound in it. Pesticide X is known to have absorption of about 50% through inhalation.
What is John’s exposure to Pesticide X and what is his dose?
Route of Exposure Exposure (grams) Dose (grams)
Dermal
Oral
Inhalation
Total
Looking at the total exposure and dose, what percentage of his exposure was a dose?
Answers
Answer:
The correct answer is - 15.13%
Explanation:
According to the question, the exposure of the pesticide X to the skin of John is by different routes and amount of the exposure is given and the percentage value is calculated as well:
Route of exposure --- exposure in gram---Dose in gram
Dermal ------------------------32-----------------------32*5/100= 1.6
Oral------------------------------2-----------------------2*90/100= 1.8
Inhalation----------------------5-----------------------5*50/100= 2.5
Total --- -----------------------39 -----------------------5.9
On the basis of this, the exposure is mainly by inhalation, the total exposure is about 39 grams about 5.9 percent. However,
The percentage of dose exposure = (5.9/39)*100
= 15.13%

What do coral reefs and estuaries have in common?
Answers
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.

Ophrys sphegodes, the early spider orchid, has flowers with yellow-green sepals and petals and one highly modified, velvety brown central petal at the base of the flower. There is single male anther is found at the tip of the column. The stigma is on the underside of the column just below the anther.
Required:
a. Is the flower complete or incomplete?
b. Is the flower perfect or imperfect?
c. Is the flower radially or bilaterally symmetrical?
Answers
Answer and Explanation:
a. This is a complete flower. Complete flowers are those formed by chalice, corolla, androecium and gynoecium. In the case of the flower presented above, we can see that it has gynoecium because it has a stigma that is part of the gynoecium composition. We can also see that she has androecium, because she has an anther that is part of the composition of androecium. The flower also has a corolla and chalice, since the chalice is formed by the sepals and the corolla by the petals.
b. This is a perfect flower, as we can see that androecium and gynoecium are present in the same flower. Imperfect flowers are those with only androecium or gynoecium.
c. The flower has bilateral symmetry, which is common in all orchids. This type of symmetry allows the flower to only be divided into two equal parts. Radial symmetry, on the other hand, allows flowers to be divided into many equal parts.

In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p).
a. True
b. False
Answers
Answer:
True
Explanation:
An allele refer to two alternative forms of the same gene. An allele is a pair of genes found on a given chromosome. Usually, every allelic pair has one which is dominant and one which is recessive.
The dominant allele is expressed while the recessive allele is not expressed.
The colour of the pea plant is controlled by a pair of alleles wherein purple (P) is dominant to white (p).
The expressed colour of the pea plant(phenotype) is dependent on the arrangement of the genes(genotype) of the pea plant.

Will mark as brainliest if correct
Answers
Answer:
The correct answer is - D. All of these are correct.
Explanation:
It is clear that the terrarium is sealed or not, if it is open to the outside environment or not. Considering it sealed and no outer interaction, then if a fake plant to this terrarium then there will be no photosynthesis will take place as there are no green plants to capture the sunlight and make glucose and no way to release oxygen for the other organisms.
If in this no green plants then the removal of CO2 will not be possible. Higher amount of carbon and without oxygen turtles would not be able to survive even though there is food for them.
According to the diagram below, what type of organism converts atmospheric nitrogen (N2) to ammonia (NH3) and then to nitrites (NO2-) and nitrates (NO3-)?
Answers
Answer: Nitrogen-fixing Bacteria
Explanation:
In the Nitrogen cycle, nitrogen fixing bacteria are very important in ensuring that plants get nitrogen to enable them grow and as animals have to eat plants, these bacteria are essential for our survival as well.
Plants are unable to use atmospheric nitrogen but nitrogen-fixing bacteria are able to synthesize ammonia from atmospheric nitrogen. They can then convert this to Nitrites and Nitrates which are more useful to plants and animals by extension.

B. All of the layers should contain fossils of complex organisms.
C. The lower layers should contain fossils of more complex organisms.
D. The upper layers should contain fossils of more complex organisms.
Answers
Answer:
D the upper layers
Explanation:
at first, lifeforms were simple. they got more complex for a variety of reasons, including to adapt to the changing earth. simple organisms will be lower down for that reason.
The lower layers should contain fossils of more complex organisms. So, the correct option is (C).
What are Fossils?A fossil is defined as the preserved remains, imprint or trace of something that once lived from a previous geological era. Examples of fossils are bones, shells, exoskeletons, fossilized traces of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.
There are four main types of fossils which are formed in different way are conducive to preserving different types of organisms. Fossils are mold fossils, cast fossils, trace fossils and true form fossils.
Fossil layers are fossils that formed in sedimentary rock that formed in layers by depositing and pressing sediments on top of each other.
Thus, the lower layers should contain fossils of more complex organisms. So, the correct option is (C).

Three complex carbohydrates that are very important in living things are starch, cellulose, and glycogen (see below).. All three of these polysaccharides are polymers of glucose, yet they behave very differently in our bodies. We can digest starch and glycogen, but not cellulose. Examine the drawing of these three polysaccharides below. What differences can you see between these molecules that might explain why
Answers
Answer:
The functional group highlighted in pink alternates its position on the carbohydrate molecule
Explanation:
Complex carbohydrates or polysaccharides are large molecular weight molecules composed of repeating unit of simple carbohydrates which are joined together by covalent bonds known as glycosidic bonds. These glycosidic bonds are foremd between the carbon at position number 1 (known as the anomeric carbon) of one simple carbohydrate and a hydroxyl group of another simple carbohydrate.
The configuration of these linkages determines the properties and functions of the complex carbohydrates. The complex polysaccharides starch, glycogen and cellulose are all composed of glucose monomers linked together by glycosidic bonds.
In storage polysaccharides such as starch and glycogen whose function is to store the simple carbohydrate glucose for when needed by the organism, the glycosidic linkages are said to be in α-linkages, placing the functional groups (CH₂OH) all on the same side.
Even the branching points in glycogen are all in α-linkages. Humans have the enzymes to break these bonds so that starch and glycogen molecules can be metabolized by the body.
In a structural polysaccharide such as cellulose, the glycosidic linkages are β-linkages which results in alternating positions for the functional groups. Since humans do not have the enzymes responsible for the breakage of these linkages, hence, we cannot digest cellulose in our bodies.

A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.
