For the following three cultures, using any resource find out if they are obligate aerobes, facultative anaerobe, or obligate anaerobe- o Escherichia coli o Micrococcus luteus o Clostridium sporogenes

Answers

Answer:

Escherichia coli - Facultative anaerobe

Micrococcus luteus - Obligate aerobe

Clostridium sporogenes - Obligate anaerobe

Explanation:

In simple terms, obligate aerobes are organisms that require oxygen to grow and metabolize molecules such as fats and sugars to produce energy. Many animals fall under this category. Other examples are Mycobacterium tuberculosis and Micrococcus luteus.

Facultative anaerobes are organisms (usually bacteria) that can grow both in the presence and absence of oxygen. The most example of this are the Escherichia coli.

Obligate anaerobes are organisms (usually microorganisms) that cannot survive when exposed to normal atmospheric concentration of oxygen. Examples are Clostridium sporogenes and Clostridium botulinum.

Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.

Answers

Answer:

The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.

Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.

Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.

How do sinkholes form? Be sure to provide a detailed explanation of sinkhole formation.

Answers

Answer:

See below

Explanation:

Over hundreds of thousands of years, layers of rocks like bedrock and limestone erode. Then, a hole or cavity forms when it erodes. Slowly, the matter above the cavity falls in. This causes it to expand. Drought is also another reason that sinkholes form in the ground.

Answer:

Sample Answer edge 2021

Explanation:

When it rains, rainwater, which is slightly acidic, soaks into the ground and becomes more acidic as it moves through the soil. When this water comes in contact with the bedrock, it reacts with the limestone, dissolving it. As the water flows through the ground, it carries the dissolved limestone away with it, enlarging the natural holes and cracks that were already present in the rock. Over time, large cavities may form in the bedrock. Sinkholes often form when the overlying sediments become too heavy for the ceiling of an underground cavity to support. The ceiling gives way and the overlying sediments collapse into the cavity.

What is rcbL, and why is it a particularly useful molecule for studying evolutionary relationships in plants and green algae

Answers

Answer:

RBCL denotes for 'rubisco protein.' It is characterized as 'a plant enzyme which catalyzes both the fixing of carbon dioxide found in atmosphere during photosynthesis and the reverse process of photorespiration.' It plays a very significant role in studying, as well as, in evaluating relations associated with phylogenetics in plants primarily along with green algae as it assists them to produce energy molecules by using carbon dioxide from the atmosphere. It has therefore been the key factor behind a number of organic carbon that is discovered in our surrounding biosphere.

3. A bacterial isolate from a urine specimen was grown in culture, Gram stained, and then tested for its ability to ferment sugars and hydrolyze various subtrates. What approach to bacterial identification is this an example of

Answers

Answer:

Phenotypic approach for bacterial identification

Explanation:

Bacterial identification can be done by conventional methods, which are based on phenotypical characteristics. These methods are much affordable and reasonable.

Phenotypical identification is based on bacteria´s observable characteristics, such as their morphology, development, and biochemical/metabolic properties.

It is important to consider that these methods do not provide absolute certainty. They can only indicate the genera or species to which the bacteria under study may belong.

Some primary evidence is usually used for fast bacteria identification:

Gram staining, morphology, growth at different media or different incubation atmospheres, glucose fermentation, spores production, motion, aerobiosis/anaerobiosis, among others.  

Knowing that the bacteria in the exposed example was isolated and grown in culture, then Gram-stained and tested for biochemical reaction, we can assume that the approach for its identification is phenotypic.

1. A week after returning from a backpacking trip, four teenagers developed nausea and severe diarrhea. All had consumed untreated water from a stream which doctors concluded was infested with the organism, Giardia. Think about the symbiotic relationships that you studied in this unit. What type of relationship exists between the teens and the organism?

2. As humans burn fossil fuels for energy, the percent of carbon stored in fossils is reduced while the carbon in the atmosphere is increased. If green plants are also being removed, how might the carbon cycle and greenhouse effect be influenced?

3. How are decomposers critical to the carbon cycle?

Answers

Answer:

Explanation:

1) The relationship that exists between the teens and the organism (Giardia) is Parasitism. Because in such symbiotic relationship one species (the parasite-Giardia) benefits while the other species (the host- the teens) is harmed.

2) Plants remove Carbon dioxide (a major green house gas) from atmosphere during photosynthesis. But, if plants are also being removed with increase in use of fossil fuels, the CO2 that escapes the fossil fuels will remain in the atmosphere for longer as there are not enough plants to "suck" them back into a stored form of Carbon. Carbon Dioxide increases green hourse effect thus green house effect will increase and earth's temperature might rise due to this.

3) Without decomposers we would not be able to continue the carbon cycle because we could not release the stored carbon from plants and animals into the atmosphere. Decomposers break down dead material from organism and release carbon dioxide into the atmosphere, where it's available to plants for photosynthesis. Without them, we could not recycle nutrients or carbons in our ecosystem and thus, they are critical for the carbon cycle.

The spinal cord consists of bundles of nerve axons forming pathways that carry incoming and outgoing messages between the brain and the rest of the body.


130 and 14C are isotopes of 12C, which has 6 electrons, 6 protons, and 6 neutrons. What is the arrangement of subatomic particles in 14c?
A. 6 electrons, 7 protons, and 6 neutrons.

Answers

The correct answer is C. 6 electrons, 6 protons, and 8 neutrons.

Explanation

An isotope is a type of atom that is characterized by having a nucleus with a different number of neutrons. Additionally, isotope atoms are those that have the same number of protons in the nucleus (in the case of carbon 6 protons), but different mass numbers. In the case of the isotope of carbon, it has 8 neutrons (2 more neutrons than the regular carbon) and 6 protons in the nucleus, that is, that its mass is 14 (6 protons + 8 neutrons equals 14). According to the above, the correct answer is C.

Answers

Answer:

The phase that not all cells enter, but is a phase where cells are not actively dividing is called the G0 or non-dividing phase.

Answer:

G₀ phase

Explanation:

Some types of cells divided slowly or not at all. These cells may exit the G₁ phase and enter a resting phase called G₀ phase. In G₀ phase, a cell is not actively preparing to divide. It's simply doing its job. For some cells, G₀ is a permanent state, while others may restart cell division given the right signals.

When an organism encounters nitrate in its environment, which condition will determine whether the nitrate is used in an assimilatory or dissimilatory manner?

a. low concentration or ammonia
b. low concentration of sulfate
c. oxygen present
d. low temperature
e. oxygen absent
f. high concentration of nitrite

Answers

Answer:

Dissimilatory- oxygen absent

Assimilatory- high concentration of nitrite

Explanation:

In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes

2. Kinases hydrolyze key phosphorylated residues.
3. Kinases phosphorylate key residues.
4. The receptor tyrosine kinase dimerizes.
5. GTPase removes a phosphoryl group from GTP.
6. Phosphatases phosphorylate key residues.

Answers

Answer:

1. Phosphatases hydrolyze key phosphorylated residues.

Explanation:

Receptor Tyrosine Kinases (RTKs) are high-affinity transmembrane protein receptors that bind to a wide variety of ligands (e.g., growth factors, cytokines, hormones). These receptors (RTKs) have a transmembrane domain and therefore these proteins act as membrane receptors, as well as exhibit catalytic activity. The intracellular C terminal region of RTKs contains catalytic domains responsible for both autophosphorylation and tyrosine phosphorylation of their protein substrates. Moreover, Protein Tyrosine Phosphatase (PTPs) are critical enzymes that remove phosphate groups from tyrosine residues in different substrates (including RTKs), thereby regulating key signaling pathways such as cell proliferation, cell differentiation, and cell-cell adhesion.

The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?

Answers

Answer:

The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).

Explanation:

Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.

In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.

In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..
