Answer:

B. an r-strategist

Explanation:

R-strategist (also known as r-selected species) refers to species whose population growth is based on the maximum reproductive capacity of the individuals under optimum environmental conditions (i.e., the biotic potential). These species are well known to produce numerous offspring and they show exponential population growth. The most common features of the R-selected species are 1-high reproductive rate, 2-rapid development, 3-early reproductive age, 4-small size,  5-short life spans, 6-poor competitive ability, and 7-high mortality. Some examples of r-selected species include rabbits, mice, marine invertebrates (e.g. jellyfish), weeds, bacteria, etc.

Answer:

Thanks so much for giving the answer!

It is r-stragery though.

k-stratergy produce fewer offspring slowly- such as an elephant.

r-strategey produce offsping rapidly- such as a (nasty) fly.

Lupus refers to autoimmune disease in which the immune system of the body  attacks its normal and healthy tissue instead of virus and bacteria. Symptoms of this disease include inflammation, swelling, and damage to the joints, skin, kidneys, heart, and lungs etc. The main cause of this disease is the environment that triggers Lupus. Chemotherapy and medications such as Nonsteroidal anti-inflammatory drugs and Antimalarial drugs etc are used for its treatment. Due to the disease's complex nature, it is often called "the of 1000 faces". In the united states there are about 16000 new cases of lupus every year. There are different kinds of lupus. This article will focus mainly on systemic lupus erythematosus (SLE), but other types include discoid, drug-induced, and neonatal lupus. Currently there is no cure for lupus, but the symptoms can be managed with care. The treatment aims to manage and prevent flare ups. The exact treatment will depend on how lupus affects the individual. Without treatment, flares can occur that may have life-threatening consequences.

Answer: Tetracycline.

Explanation:

A plasmid is a small circular DNA molecule found in bacteria that is separate from the bacterial chromosome and replicates independently of it. They encode for certain genes that play a key role in antibiotic resistance. Restriction enzymes are endonucleases that catalyze the cleavage of phosphodiester bonds in different regions located within a DNA strand. PstI is an example of an endonuclease, it is a type II restriction enzyme produced by the microorganism Providencia stuartii that possesses a restriction target in double-stranded DNA dependent on an unmethylated, palindromic, asymmetric sequence, and in this example, it cuts the plasmid at a single site in the ampicillin-resistance gene. After that, the DNA is annealed with another fragment of DNA and this new recombinant molecule is used to transform E. coli cells. Transformation is a key step in DNA cloning because it occurs after restriction enzyme digestion and ligation treatments and transfers newly made plasmids into bacteria. So these bacterias will have a new fragment of DNA, which still has a tetracycline resistance gene but it no longer has the ampicillin resistance gene because it was disrupted by the restiction enzyme. Thereby, the antibiotic resistance phenotype is the tetracycline resistace.

Answer:

Explanation:

Repressor molecules, as we recognize them to be proteins occur as transcription factors that may function on their binding sites within the same genome or even on a different genome.  

As a result, repressor molecules behave in a trans-active manner. Operator, on the other hand, acts as a binding site mostly on the chromosome genome which can only trigger downstream genes. As a result, Operators are cis-acting.

In this scenario, if we give the system a Plasmid containing a wild-type repressor gene, the repressor molecules would only attach to the usual Operator sites.

In the 1st scenario:  

The Operator is regular and normal, but I- is mutated. As a consequence, the additional extra plasmid's normal repressor molecules will stick to the operator site, causing suppression or repressed expression.

In the 2nd scenario: genome

The repressor is natural, but Oc is mutated. As a consequence, the additional extra plasmid's normal repressor molecules would not adhere to the operator region, resulting in the same Constitutive expression.

Answer:

1. Map-based genome sequencing: a; c; f; g

2. Whole-genome shotgun sequencing: b

3. Both sequencing methods: d; e

Explanation:

Map-based genome sequencing is a method that makes use of a reference genome sequence in order to determine the relative position of the DNA fragments before they are sequenced. This method is useful to determine the position of repetitive DNA fragments (for example, duplicated genes, repetitive non-coding regions, etc.) and Transposable Elements. Therefore, map-based genome sequencing is a suitable approach for large genomes (which are usually composed of repetitive sequences). On the other hand, in whole-genome shotgun sequencing, DNA sequences are obtained before the correct order of these DNA fragments is known. In this method, the genome is fragmented randomly into small DNA sequences (between 100 and 1000 base pairs), which are subsequently sequenced through the chain-termination sequencing approach (i.e., Sanger sequencing) and finally ordered by using bioinformatic tools that assemble overlapping reads.

Answer:

Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Species evolve because of the accumulation of mutations that occur over time. ... This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation

Answer:

This question lacks options, options are:

A. Acidophiles B. Alkaliphiles C. Neutrophiles

The correct answer is A. This drop most likely causes many acidophiles to be inhibited.

Explanation:

Microbial fermentation is one of the basic biotechnical processes for the efficient formation of active substances. Fermentation uses fungi, bacteria or cell cultures to transform raw materials into chemicals. Acidophiles is usually bacteria and other very simple organisms that are capable of developing in conditions of too low a pH for most forms of life. Each microorganism has a pH range in which it can grow and a well-defined optimum pH. Depending on the pH, we find acidophiles (1.1 - 5.5), neutrophilic (5.5 - 8.0) and alkaline (8.5 - 11.5) microorganisms, which grow well in acidic, neutral and alkaline pH respectively. Fermentation is carried out to prevent the development of other microorganisms that can alter the quality of the food. Anaerobic digestion is a microbial fermentation in the partial or total absence of oxygen that gives rise to a mixture of gases, in which methane and carbon dioxide are mainly found. Anaerobic microorganisms mainly obtain their energy through the use of fermentation pathways, where organic compounds such as acids and alcohols, among others, basically serve as final electron acceptors. Bacteria, in carrying out these processes, are conditioned by some physical and chemical factors, which enable their proper development, these factors are: loads of organic matter, volatile fatty acids, temperature, alkalinity, nutrients and the presence of N and P , among others.

The digestion of food in the absence of oxygen and release of oxygen is called fermentation.

Microbes that perform the fermentation are usually anaerobic bacteria.

Microbial food fermentation is often performed as a preservation method to inhibit the growth of food spoilage microorganisms that may be present in or on the food. The fermentation process often leads to an overall pH decrease of the food to levels below 4. This drop most likely causes many acidophiles to be inhibited.

Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions.

The lower ph makes the food acidic, due to acidic in nature the bacteria are not able to survive in that conditions.

b. messenger ribonucleic acid

a. The complementary DNA strand is the sequence that pairs with the given DNA strand. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Therefore, the complementary DNA strand of "AGGTCAGG" would be "TCCAGTCC".

b. The mRNA strand is synthesized based on the complementary DNA strand. In mRNA, thymine (T) is replaced by uracil (U). Therefore, the mRNA strand corresponding to the given DNA sequence "AGGTCAGG" would be "UCCAGUCC".

c. To determine the amino acids produced, we need to identify the codons (groups of three nucleotides) in the mRNA strand and refer to a codon chart (also known as a genetic code chart). Here's an example of how the codons in the mRNA strand "UCCAGUCC" can be translated:

UCC (Serine)

AGU (Serine)

CCU (Proline)

Therefore, the resulting amino acid sequence would be Serine-Serine-Proline.

Answer: Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm. During translation, the genetic code in mRNA is read to make a protein. In the first step, called transcription, the genetic code in DNA is copied by RNA. In the second step, called translation, the genetic code in RNA is read to make a protein. A mutation is a change in the base sequence of DNA or RNA.
