Emma and her younger brother were running a race. After 30 minutes, Emma started feeling pain in her lower leg muscles. a. Suggest the reason for this.

Answers

Answer 1

Answer:

This is due to lactic acid accumulation in Emma's leg muscles.

Explanation:

In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.

This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.

Answers

Answer:

2. Gene

3. DNA

1. Pre-mRNA

4. mRNA

Explanation:

Transcription is the first step of gene expression in which a DNA molecule serves as template for the synthesis of mRNA. In the process of transcription, a Gene present on the DNA molecule is transcribed by RNA polymerase using complementary base pairing rule.

After the gene is transcribed, a pre-mRNA is formed. This mRNA is so called because it is immature. The pre-mRNA undergoes processing such as polyadenylation, splicing etc. to become a mRNA.

Hence, based on this, the order is:

Gene → DNA → pre-mRNA → mRNA

Explain the basic process of transcription. Include a description of the major intracellular structures involved.

Answers

Answer:

Transcription is the cellular process of RNA synthesis by decoding the information contained in a DNA fragment  

Explanation:

Transcription is the process by which the genetic information contained in a fragment of DNA called 'gene' is used as a template to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently used to synthesize a protein by the process of translation. In eukaryotic organisms, transcription involves a DNA template strand, which contains both non-coding (i.e., promoter, introns) and conding (i.e, exons) regions, and an RNA polymerase that adds nucleotides to the growing RNA strand using as a template a DNA strand. Both in prokaryotes and eukaryotes, transcription occurs in three basic steps: 1-initiation, where DNA strands separate, 2- elongation, where the RNA polymerase moves on the DNA sequence to synthesize an RNA molecule, and 3-termination, where transcription terminates depending on the sequence in the RNA (eukaryotic transcription has an additional step known as RNA processing).

Explanation:

Use Chargaff's rules which states that 100% is total of all 4 bases and Adenine and Thymine need to have 1:1 ratio and Cytosine and Guanine need to have 1:1 ratio

21% Adenine and 21% Thymine

21% + 21% = 42 100 - 42 = 56 56 / 2 = 28

Thomas Malthus was an economist who influenced Darwin's developing theory of evolution. Malthus observed that the birthrate among humans exceeded the death rate. If this trend continued, soon there would not be enough resources to support human population growth. He reasoned that the only things capable of stopping human population growth were famine, disease, and war. Darwin applied this thinking to animals and plants as well, noting that far more offspring were produced than survived to a reproductive age. 2. How did Charles Darwin build on the work of Thomas Malthus to develop the idea of evolution by natural selection

Answers

Answer:

The work of Thomas Malthus help and influence Darwin Thomas to refine his theory of natural selection by explaining that there is a meaningful competition between the individuals of a particular species or population for a specific resource such as food or shelter.

Thomas Malthus predicted that the human population is reproducing faster than its death race and will lead to growing faster than space and food supplies needed to sustain it. Darwin concluded further that If all offspring of almost any species survived for several generations, they would overrun the world and therefore a healthy and meaningful competition is present and to overcome this natural selection takes place as the individual adapt will ultimately survive.

Two distinct bands appear in a single lane at the completion of an SDS-PAGE analysis of an unknown protein. Select one: a. These bands represent two subunits of a homodimer. b. Each band represents a different sized subunit of a multimeric protein. c. Each band represents a protein subunit with different charge to mass ratio. d. These bands represent two subunits of a heterodimer. e. These bands represent two separate subunits of identical size.

Answers

Answer:

b. Each band represents a different-sized subunit of a multimeric protein.

Explanation:

SDS-PAGE analysis allows the separation and discrimination of proteins according to their molecular weight. The technique separates proteins in an electromagnetic field.

The SDS-PAGE technique makes proteins move in solid support -gel- by the action of the electric field. The distance reached by each protein is proportional to their molecular weight. The protein separation from a mixture results in bands that reflect their size.

SDS is a detergent that denaturalizes the protein and sets a relation charge size, such as that the motion of the protein in the gel is proportional to its weight. The bigger the protein is, the stronger interaction with the polyacrylamide gel there will be.  The speed of displacement in the electromagnetic field is inversely proportional to the protein size.

Answers

Complete question:

Scientists have proposed more than two dozen ways to define species. One commonly used definition, called the biological species concept, holds that populations belong to the same species if they can contribute genes to a common gene pool. Reproductive barriers block gene flow between different species. Gene flow between populations tends to hold the gene pool of a species together.

Part A - Comparing species definitions

Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species (morphospecies) concept.

Drag each characteristic to the appropriate bin based on the species concept(s) to which it applies → You will find this in the attached files

Answer:

Not applicable for extinct species → Biological Based on evolutionary history → Phylogenetic  Relies on similarities in structure → Morphological Accommodates asexual reproduction / Species acceptance criteria can be subjective → Morphological and PhylogeneticUsed by scientists in classification → Morphological, Phylogenetic, and Biological

Explanation:  

The biological concept states that species are population groups that -in a real or potential way- can mate and reproduce, but are reproductively isolated from other groups.  

Individuals belonging to a species cannot reproduce with members of other species.  

This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.  

Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.  

Finally, this concept is not adequate concerning hybridization zones, something to be expected considering evolutionary processes. This is the reason why it has been less accepted by botanists, as some plant species hybridize with other species.  

The phylogenetic species concept defines species on a determined time and through time, and these are the horizontal and vertical species concepts, respectively. The species group is considered to be the less inclusive monophyletic group.

According to the phylogenetic concept, a species is a monophyletic group whose organisms share synapomorphies.

The establishment of species relies on molecular markers.

The morphological species concept defines species according to the shared morphological characteristics shared by all the members of the species. It is a descriptive method to separate species.

When a group differs considerably at a morphological level from another group, it is defined as a different species.

Some limitations might emerge from this species concept. It does not consider variability among individuals,

Individuals of the same species might be polymorphic, exhibiting morphological differences between organisms. These individuals would be considered to be different species following the morphological concept. Some different species might be morphologically similar, despite being different. These species might be considered as one following the morphological concept.
