Which of the following is NOT a function of an antibiotic?
A. targeting the ribosome that inhibits protein synthesis, causing the cell to not function correctly
B. attacking the mitochondria, inhibiting the production of sugars that give the cell energy
C. inhibiting the production of the cell wall and breaking down what is present
Answer:
B. attacking the mitochondria, inhibiting the production of sugars that give the cell energy
Explanation:
Antibiotics can't attack on the mitochondria of the cell because mitochondria provides energy to the cell. Mitochondria is also known as power house of the cell means that it provides energy to the cell in order to continue its activities. If antibiotic attack on mitochondria of the cell, the cell has no energy for performing its activities that leads to cell death so that's why we can say that antibiotic can't attack on the mitochondria of the cell.

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.
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.

If a sample of DNA is 21% adenine, it would be % cytosine.
Answer: 28%
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
28% Cytosine and 28% Guanine

The electrochemical system in the body for communicating, processing, and
storing information is the:
A. endocrine system.
B. nervous system.
C. brain lobe system.
D. neural feedback system.
SUBMIT
Explanation:
The correct answer is the nervous system. It is because the CNS or the nervous system is the one responsible for sending or transmitting signals from the brain throughout the body in order for it to function, this also involves of having to communicate, process and store memory in an individual.

Order the following words for Transcription
1 pre-mRNA
2.Gene
3 DNA
4mRNA
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

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. Three of the most prominent definitions of species are the biological species concept, the phylogenetic species concept, and the morphological species concept. For each characteristic, identify the a
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 BiologicalExplanation:
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.What percentage of the global water supply is fresh water? 6 percent 35 percent 1 percent 10 percent
