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

The 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.

[tex]\frac{48}{2} = 24[/tex] mg decays and 24 g remains left.

[tex]\frac{24}{2} = 12[/tex] mg decays and 12 g remains left.

[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.

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.

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.

Answer:

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.

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.

Answer:

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Photosynthesis produces the oxygen to replenish oxygen that is used up by living organisms during respiration. Carbon dioxide produced during respiration is one of the reactants plants need to perform photosynthesis. Photosynthesis and cellular respiration are both part of a mutually beneficial relationship.

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).

The function of cholesterol in the cell membrane is C. To make more room inside the cell membrane.

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.

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.

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.
