Identify the control group for the rat experiments described in the Paralytic Shellfish Poisoning Scenario.
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, the control group of an experiment is the group in which every other group of the experiment is firstly compared with. This is because control groups are usually not administered with any form of treatment. Thus, the control group of the experiment/scenario referred to in the question will be the group that did not receive any form of treatment and was probably given water or placebo.

Answer:
This question is incomplete.
But from what is provided, the answer is biotechnology
Explanation:
The use genes of microorganisms to produce human insulin involves the use of biotechnology via the process of recombinant DNA technology. Recombinant DNA technology involves the joining together/ligation of two or more DNA molecules (in this case the DNA of the microorganism and the DNA sequence coding for insulin in humans) of different species in a microorganism. The microorganisms used here are called transcription vector. This is because the microorganisms are only used to duplicate/produce the insulin and the insulin are not expressed in the microorganisms. E. coli and Saccharomyces cerevisiae are two most common microorganisms used in the production of insulin.

If the amount of carbon-14 in the original sample had been 48 grams, about how much carbon-14 would
have been left after 17,100 years?
Answer:
don't know i have the same question
Explanation:
If the amount of carbon-14 in the original sample had been 48 grams, 6 gm carbon-14 would have been left after 17,100 years
Half-lifeThe amount of time required for a quantity to fall to half its value as measured at the beginning of the time period.
The half-life (t½) of C-14 is 5700 years, which means that after 5700 years half of the sample would have decayed and half would be left as it is.
After 5700 years ( first half-life)[tex]\frac{48}{2} = 24[/tex] mg decays and 24 g remains left.
After another 5700 years ( two half-lives or 11400 years)[tex]\frac{24}{2} = 12[/tex] mg decays and 12 g remains left.
After another 5700 years ( three half-lives or 17100 years)[tex]\frac{12}{2} = 6[/tex] mg decays and 6 g remains left.
Thus, after three half-lives or 17100 years, 6 g of C-14 will be left.

What is the problem which fermentation is able to FIX?
Cell has a limited supply of NAD
Cell has a limited supply of oxygen
Cell has too few mitochondria
Cell has too many glucose
Answer:
Cell has a limited supply of NAD+Explanation:
Cellular respiration occurs in the cytoplasm, where glucose is broken down for energy processing. Energy is produced by aerobic respiration in the presence of oxygen, whereas anaerobic respiration can be carried out in an oxygen-deprived environment.
Fermentation is one kind of anaerobic respiration- here, the cells use glucose to generate a Net 2 molecules of ATP from the 6carbon sugar. Glucose is first converted to pyruvate, which is oxidized in a complex process. While 4 ATP are produced in fermentation, 2ATP are used in regenerating NAD+ from NADH2.
Two types of fermentation include lactic acid fermentation and alcoholic fermentation. These occur in single-celled, and multicellular microbes.

What is the function of cholesterol in the cell membrane?
A. To allow substances too pass through
B. To prevent the hydrophobic tails from sticking together
C. To make more room inside the cell membrane
D. To help the cell recognize self and non self
The function of cholesterol in the cell membrane is C. To make more room inside the cell membrane.
What is the importance of the cholesterol?Cholesterol affects the bilayer structure of biological membranes in a variety of ways. It alters lipid bilayer fluidity, thickness, compressibility, water penetration, and intrinsic curvature.
Cholesterol molecules control the fluidity of the cell membrane, which allows the cell to maintain its shape. If cholesterol is missing from the cell membrane, excess fluidity may lead to cell lysis, or the breakdown of the cell.
As a result, cholesterol is required for cell membrane stability.
In conclusion, the correct option is C.

In the transcription of DNA to mRNA, for the DNA sequence 3'-AGGTCTCAC-5' corresponds to an mRNA sequence 5'-UCCAGAAGUG-3'.
Explanation:
Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.
The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.
In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.

A scientist is using a species of green algae to study the electron transport chain in photosynthesis. He uses a laser to inactivate all of chlorophyll A in the algae but leaves chlorophyll B intact (case 1). In a separate experiment, the scientist applies a chemical to the algae that inhibit PS I but do not affect PS II (case 2).
Which of the following results is expected?
A)in case 1, only PS I completely loses function; in case 2, no proton gradient is produced.
B)In case 1, only PS I completely loses function; in case 2, a proton gradient is still produced.
C)In case 1, both PS I and PS II completely lose function; in case 2, no proton gradient is produced.
D)In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Answer:
D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Explanation:
The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.
The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.
In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.

8. Which organisms act as a bridge between the nitrogen in the atmosphere and the nitrogen on land?
Answer:
Well, Bacteria plays a key role in the nitrogen cycle, but also some species of nitrogen-fixing bacteria are free-living in soil or water, while others are beneficial symbionts that live inside of plants.
Explanation:
Bacteria act as a bridge between the nitrogen in the atmosphere and the nitrogen on land.
• Nitrogen moves into the living world with the help of microbes, that is, bacteria. The bacteria transform atmospheric nitrogen, that is, N2 into usable biological forms by the process of nitrogen fixation.
• Some nitrogen-fixing bacteria are free-living in water or soil, while some are beneficial symbionts, which reside within the plants.
• The nitrogen-fixing bacteria capture the atmospheric nitrogen by transforming it to NH3 that can be taken by the plants and are utilized to produce organic molecules.
• The nitrogenous molecules are passed onto animals when they consume plants. These gets incorporated within the body of the animal and are excreted in the form of urea in urine.
Thus, bacteria act as a bridge between the nitrogen in the atmosphere and the nitrogen on land.

In the experiment determining the parental genotype of plant seedlings from a monohybrid cross, if the dominant color was green (C) and the recessive color was white (c), what would the parental genotype have been if plate 1 only contained white seedlings instead of all green
Answer:
cc × cc
Explanation:
This question involves a single gene coding for plant seedling. The green allele (C) is dominant over the white allele (c). This means that the green allele will mask the phenotypic expression of the white allele in a heterozygous state (Cc).
In this experiment where plate 1 only contained white seedlings instead of all green, this illustrates that all the offsprings were recessive. This is because the parental genotypes were both recessive for the color trait i.e. cc.
Note that, the recessive trait can only be expressed when the recessive alleles are present in a gene. Therefore, the parental genotype would have been cc × cc, in order to give rise to all offsprings with the recessive trait (white colour).

Flagella proteins are found in the extracellular matrix of lung tissue. How do the cells of the lung detect these proteins? a. complement system b. toll-like receptors c. eosinophils d. NOD e. helper T-cells
Answer:
The correct answer is b.
Explanation:
TLRs are transmembrane type proteins 1, they are abundantly expressed in fibroblasts and epithelial cells, as well as in cells of the immune system, including macrophages, dendritic cells, B and T lymphocytes, and their expression is regulated by pathogens, cytokines, microenvironmental factors, and possibly endogenous ligands. Due to their location and the type of ligands that bind them, these receptors have been divided into two large groups: the TLRs of cytoplasmic membranes (TLRs 1, 2, 4, 5, 6 and 10) and the TLRs of endosomal membranes (TLRs 3 , 7, 8 and 9). TLR5 located in the basolateral membrane of epithelial cells recognizes flagellin, a structural protein that makes up flagella.
