Your first assignment is to provide information to the firm BigMoney Inc., a chemical producer in Kansas interested in using microbes to clean toxic spills (bioremediation). BigMoney Inc. has had a major spill of inorganic S that contaminated the soil around their plant. Scientists at BigMoney have developed mechanisms for removing H2S from soil, but have not found one for S. They want to know on a strictly theoretical basis (regardless of whether bacteria exist in nature that actually do these specific reactions) if there are any types of bacteria that could use S to give rise to H2S. (7 points total)

S ? H2S (-0.274)

a) is this an oxidation or reduction?

b) is S serving as an electron acceptor or donor?

c) Which of the following metabolisms (aerobic respiration, anaerobic respiration, aerobic chemolithotrophy and anaerobic chemolithotrophy) could be used to carry out this reaction? You can assume the reaction given above is either the initial oxidation reaction or the final reduction reaction. You must think about whether each of these metabolisms can oxidize or reduce inorganic materials. Remember, think strictly theoretically. Note, you must indicate ALL metabolisms that could be used. (1 point)

d) For each of the metabolisms that could be used, describe exactly how H2S will be formed providing the following information: (5 points)

Is the initial electron donor (from where are the electrons being taken) organic or inorganic?

Which of the pathways discussed in class (glycolysis, TCA, electron transport chain, chemolithotrophy, photosynthesis, and fermentation) will be used to get the electrons?

Is the final electron acceptor oxygen or not oxygen, and is it organic or inorganic?

Please provide a specific example of a half reaction (either initial oxidation or final reduction) that would work with the half reaction provided in this scenario, and briefly describe why it was chosen. Hint: your answer must consider the reduction potential of the electron acceptor compared to that of the electron donor and the half equation given must be either the donating or accepting reaction. Note: you may assume other molecules, both organic and inorganic, are present in the soil.

What are the different types of leaves that plants have?

Answers

Answer:

There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant. The most obvious aspect to examine is the shape of the leaf. If it is an uninterrupted shape, it is simple. If the shape divides into smaller leaf sets the leaf is compound. Identifying plant leaves that are compound divides them into subsets.

Can someone please do a summary on how wind works? 7-9 sentences please I will mark brainliest!

Answers

Answer:

Wind is the movement of air. It forms when air moves from areas of high-pressure to areas of low pressure. These pressure differences are caused by temperature differences on Earth's surface. The movement is a result of different places on Earth receiving different amounts of energy from the sun. Two types of winds are global and local. Global wind systems determine weather patterns for the entire planet. Local winds are sea and land breezes that occur due to uneven absorption of solar energy.

mineral appears to emit green and blue light in the dark.

use the drop-down menu to answer the question.

what property is the mineral in this image demonstrating?
a. magnetism
b. fluorescence
c. luster
d. streak

help me asap. pls.

Answers

The answer would be b. Fluorescence

When a particular wavelength of light, such as ultraviolet (UV) light, electron beams, or x-rays, are focused on a mineral, fluorescence takes place, hence option B is correct.

What is the property of minerals?

Calcite, fluorite, and sodalite are among the more popular fluorescent minerals, however there are many more as well. When exposed to UV light, many gemstones, including diamonds, rubies, emeralds, amber, and opal, will glow

This light stimulates the mineral's electrons, forcing them to momentarily move to a higher orbit.

Naturally, mine wastes and tailing heaps provide excellent locations for any mineral, including fluorescents.

Therefore, nearly everywhere that has a good assortment of white light minerals also has fluorescent minerals, hence option B is correct.

Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.

Answers

Answer:

The correct answer would be -

RNA - AUG GGG CCU UAC UAA

Amino acid -methionine-glycine-proline-tyrosine -stop codon

Explanation:

In the process of protein synthesis, the first process is known as transcription which involves the transcribing the mRNA strand from the DNA strand in a complementary manner. In this manner, Adenine transcribes into uracil and cytosine transcribe into guanine similarly thymine into adenine and guanine into cytosine.

Then, DNA strand - T-A-C-C-C-C-G-G-A-A-T-G-A-T-T will change into AUG GGG CCU UAC UAA and every three codes represent a triplet codon that translates into an amino acid first code called start codon and normally code for methionine (AUG) and last code for stop and does not code any amino acid.

Then, the amino acid will be - methionine-glycine-proline-tyrosine -stop codon

Which of the following data could best support the claim that species B arose from a speciation event in Lake I?

Answers

Answer: B

Explanation:

DNA analysis shows fewer differences between species A and species B in Lake 1 than species B and the populations in Lake 2

Speciation is defined as the mechanism through which new species or organisms are created.

What is Speciation?

Speciation is an evolutionary mechanism in which the population of certain organisms evolves and becomes distinct species. It is the phyletic evolution within a lineage or lineage.

In the given image, the speciation of organisms A and B shows that the difference in the genetic sequence of species and Species B in Lake I were somewhat related. Species B showed many differences to the organisms of Lake II.

Thus, species A and species B in Lake I may have arisen due to speciation.

Answers

The answer is A: sac that stores water, nutrients, and waste products :)

The vacuoles are the structures found inside the cells that store water, nutrients as well as waste products. So the correct option is option A.

The vacuole plays a vital role in many cells. Mature cells of all land plants, most fungi, and algae (with the exception of prokaryotes) contain vacuoles. On the other hand, animal cells and immature plant cells (as well as some highly immature plant cells (stone cells) contain no vacuoles.

These vacuoles store the essential nutrients and water that a cell needs to survive. They also contain the waste of the cell and protect it from contamination.

As a naturalist, you are responsible for training volunteers in the identification of the types of amphibians. The volunteers will use this information to correctly describe the animals to school groups that will visit your nature center. The training documentation for the volunteers lists important characteristics of the different groups of amphibians, but you notice that one of the items on the list is incorrect. Indicate which description is not correct.
A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
C. Some adult salamanders retain larval characteristics such as external gills.
D. Most caecilians can be found burrowing in the soil of tropical forests.

Answers

Answer:

B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.

Explanation:

Amphibians are vertebrates which can live both on land and in water. they are cold-blooded and therefore, depend on warmth from sunlight to become warm and active. Their young live fully in water respire using gills. The adults have moist skins through which they respire and therefore, live in moist places or near water to keep their bodies from drying out. Many adult amphibians also have poison-producing glands in their skin to ward off predators. Poisonous amphibians usually display a warning coloration. . The species in this group include frogs, toads, salamanders, caecilians and newts.

Considering the above descriptions:

A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.

True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.

B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.

False: Some frogs such as poison frogs as well as some salamanders such as the California newt and the red eft which a brightly colored terrestrial juvenile form of the eastern newt is highly poisonous. advertise their distasteful nature by bright coloration.

C. Some adult salamanders retain larval characteristics such as external gills.

True: Some adult salamanders retain larval characteristics such as external gills. e.g. species such as the mudpuppy (Necturus maculosus) retain their gills throughout their lives.

D. Most caecilians can be found burrowing in the soil of tropical forests.

True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.
