Bacteria that are Gram Stain Positive have several teichoic acids which are resistant to decolorization. True False

Answers

Answer 1

False.Gram-positive bacteria are characterized by the presence of a thick layer of peptidoglycan, which is cross-linked by glycoproteins called muramic acid and N-acetylmuramic acid. This layer of peptidoglycan is responsible for the Gram stain reaction, which stains the bacteria blue.

Teichoic acids are a type of polysaccharide that are found on the cell wall of Gram-positive bacteria. They are made up of repeating units of D-glucose and D-mannose, and they play a role in maintaining the integrity of the cell wall and inhibiting the growth of other bacteria.

Teichoic acids are not resistant to decolorization, and the Gram stain test does not rely on this property to differentiate between Gram-positive and Gram-negative bacteria. Instead, the Gram stain test relies on the differences in the thickness and composition of the cell wall between the two types of bacteria.

true or false? the main function of lymphocytes is phagocytosis of bacteria and other invading microorganisms. true false

Answers

Answer:

true

Explanation:

False. The main function of lymphocytes is not phagocytosis of bacteria and other invading microorganisms.

What is the main function of lymphocytes?

Lymphocytes are a type of white blood cell (WBC) that play a crucial role in the immune system. They are produced in the bone marrow and are found in the blood and lymphatic tissue. Lymphocytes are divided into three main types: B cells, T cells, and natural killer (NK) cells. The main function of lymphocytes is to recognize, bind to, and eliminate specific foreign substances such as viruses, bacteria, fungi, and parasites. They do this by producing specific antibodies against the invading organisms or by directly attacking the cells that harbor them. Lymphocytes also play a role in immunological memory, which allows the body to recognize and respond to previously encountered pathogens more quickly and effectively. Overall, the main function of lymphocytes is to provide the body with immunity against infections by detecting and eliminating foreign microorganisms. They do not perform phagocytosis, which is the process by which specialized cells called phagocytes engulf and digest microorganisms.

Two fruit flies that are heterozygous for body color and eye color are crossed. Brown body color is dominant to black body color. Red eye color is dominant to brown eye color. Use the Punnett square to determine the ratio of offspring with: Brown body and red eyes Brown body and brown eyes : Black body and red eyes : Black body and brown eye.

Answers

The ratio of offspring that possess the following phenotype is as follows:

Brown body and red eyes: 9Brown body and brown eyes: 3Black body and red eyes : 3Black body and brown eye: 1

This question involves two genes coding for body color and eye color in fruit flies respectively. The brown body color allele (B) is dominant over the black body color allele (b) in the first gene while the red eye color allele (R) is dominant over the brown eye color allele (r) in the second gene.

In a dihybrid cross between two fruit flies that are heterozygous for both genes i.e. BbRr × BbRr, the allelic combinations of gametes produced by each parent fruit fly will be:

BbRr- BR, Br, bR and br

Using these gametes to complete a punnet square (see attached image), 16 possible offsprings will be produced in a ratio 9:3:3:1 where;

Brown body and red eyes (B_R_) : 9Brown body and brown eyes (B_rr) : 3 Black body and red eyes (bbR_) : 3Black body and brown eye (BbRr) : 1

Decomposers play a critical role in the flow of energy through an ecosystem:

They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Decomposer bacteria are responsible for fixing nitrogen in the soil, meaning they transform nitrogen into a form that can be used by other organisms in the food chain.Decomposition is also important because it is part of the global carbon cycle. The carbon cycle is the cyclical movement of carbon atoms from the atmosphere to the biosphere/lithosphere and back to the atmosphere.

Answers

Answer:

Specific body defence mechanism are resistance that are directed against only one specific invader while,

Non specific defence mechanism protects against any of an enormous range of possible dangers.

Explanation:

NON SPECIFIC DEFENCE MECHANISM are the first lines of general defence, they prevent entry and minimise further passage of microbes and other foreign material into the body. There are five main non specific defence mechanisms, these include:

--> defence at body surface

--> phagocytosis

--> natural antimicrobial substances

--> inflammatory response

--> immunological surveillance

Using PHAGOCYTOSIS as a named example of non specific defence mechanism. This involves phagocytes such as the macrophages and neutrophils which are able to trap any invading microbes either by engulfing them or by extending long pseudopodia towards them which grasp them and reel them in. These cells are NON SELECTIVE in their targets.

SPECIFIC BODY DEFENCE MECHANISM directs its actions against a specific invader. In addition immunological memory develops which confers long term immunity to specific infections. The immunity could be cell mediated or antibody mediated immunity.

Using CELL MEDIATED IMMUNITY as an example, Cytotoxic T-cells directly inactivate any cells carrying antigens. This means they are SELECTIVE in their targets. They attach themselves to the target cell and release powerful toxins, which are very effective because the two cells are so close together. This leads to destruction of abnormal body cells such as infected cells and cancer cells.

The electron transport chain is the process by which electrons are transferred from the oxidation of food molecules such as glucose to the reduction of oxygen molecules.

The electron transport chainIt is an important part of cellular respiration and is responsible for producing most of the energy used by cells. The products of the electron transport chain are ATP, NADH, FADH₂, H₂O, and CO₂. ATP (Adenosine Triphosphate) is the main energy currency of the cell and is produced when the energy released from the electron transport chain is used to add a phosphate group to ADP (Adenosine Diphosphate). NADH (Nicotinamide Adenine Dinucleotide) and FADH₂ (Flavin Adenine Dinucleotide) are coenzymes which reduce NAD+ and FAD respectively during oxidation reactions and produce energy which is then used to synthesize ATP. H₂O (Water) is produced when oxygen molecules are reduced by the electron transport chain. CO₂ is a byproduct of the oxidation of food molecules. It is generated when the electrons from the oxidation of food molecules are transferred to the oxygen molecules.Therefore, the products of the electron transport chain are ATP, NADH, FADH₂, H₂O, and CO₂.

gene.
(i) Describe the stages that a scientist would complete to obtain this gene.

Answers

Answer: See Below

Explanation:

1. The scientist would need to identify the gene for a protein that would make it glow. For example Aequorea victoria, the jellyfish that produces green fluorescent protein (GFP) is the most common type of fluorescent tag use in biotechnology. This would be done by completing genetic sequencing to identify the gene of interest from the jellyfish cell.

2. The gene could then be amplified through PCR. Assuming this is a bacterial cell, a vector such as pUC19 could be used. The vector and the PCR amplified product would have to be digested. A double digest is recommended to ensure the gene inserts in the proper conformation.

3. Heat shock the plasmid into the cell and proceed on to Blue/White screening to identify which cells contain the gene of interest. You can then isolate and grow the culture containing the GFP gene and induce with IPTG to produce the protein that would make it glow.

Alternatively you could buy a pre-made plasmid from AddGene containing the GFP gene for 75$, complete a miniprep on the cells and heatshock. Either way works.
