During translation, the amino acid detaches from the transfer RNA molecule and attaches to the end of a growing protein chain when
a. the ribosomal RNA anticodon binds to messenger RNA codon.
b. the transfer RNA anticodon binds to the messenger RNA codon.
c. a "stop" codon is encountered.
d. the protein chain sends a signal through the nerve cells to the brain.
The correct option is B ; The transfer RNA anticodon binds to the messenger RNA codon. During translation, ribosomal subunits form a sandwich on the strand of mRNA,
where they bind tRNA molecules bound to amino acids (circles). As the ribosome decodes the mRNA sequence into a polypeptide, or new protein, a lengthy chain of amino acids appears.
The tRNA that has lost an amino acid is freed. It can then attach to another amino acid molecule and be reused later in the protein-making process. The ribosome advances the mRNA three nucleotides at a time via a ratcheting process.

3) Convergent evolution occurs when two species living in

b) different areas become reestablished and are able to reproduce.
c) the same area are competing for the same resource thus causing one to evolve away from the other.
d) different areas evolve similarities through natural selection acting on those characteristics.
Non-random mating will have the lowest chance of reversing the population's anticipated loss of the b allele. Small populations typically experience a faster loss of genetic diversity than big populations due to stochastic sampling error.
A and B are the best options for 2nd question. Disruptive selection and directional selection kinds of selection may enhance the proportion of lizards with large jaws when applied to a population of reptiles with variable jaw sizes.
It is wise to select option d for 3rd question. When two species that are geographically separated from one another evolve similar traits due to natural selection acting on those traits, this is known as convergence.
This is because small populations increase the likelihood of some gene variants being lost by random chance. Selection, which boosts advantageous alleles and eliminates harmful ones, and genetic drift, which changes frequencies arbitrarily as some parents pass on more or fewer alleles to the following generation, are the two processes in a population without migration that alter allele frequencies.
According to our calculations, the population's predicted loss of the b allele will thus have the lowest likelihood of being reversed by non-random mating.

What is your preliminary diagnosis? 2) What is the most likely causative agent for this condition? 3) There is a potential risk for progressing to a more serious condition. What is it?
Painful urination with fever and constant urge to urinate may indicate urinary tract infection. Preliminary diagnosis would be the patient is suffering from a upper urinary tract infection as she has fever along with other symptoms of UTI.
This can be confirmed by doing an urine culture. An urine culture will help identify the causative agent and will help in further treatment. The most likely causative agent in UTI are bacteria, especially Escherichia coli in majority of cases, with Staphylococcus saprophyticus in some cases. These usually travel up to the bladder from the rectum. Other causative agents may be fungi or viruses in rare cases.
Women are more prone to UTIs than men as they have a shorter urethra than men. UTI's may occur during intercourse or it sometimes may be hereditary. Sometimes it may have be acquired from pubic restrooms or hospitals or due to the use of catheters but it seems that is not the case in this patient.
Untreated or unrecognised UTIs may turn to serious condition very quickly. Untreated UTI may result in infection in the kidney leading to cloudy and oul smelling urine, blood in the urine, back pain.

Where do I find motor tracks in the spine? (Posterior or Anterior)?
Answer:
Anterior
Explanation:
Motor tracks in the spine can be found in the anterior (front) portion of the spinal cord. The spinal cord is a long, slender bundle of nerve tissue that extends from the base of the brain down through the spinal column. It is divided into two main regions: the posterior (back) region, which contains sensory neurons that carry information about sensation from the body to the brain, and the anterior (front) region, which contains motor neurons that carry information from the brain to the muscles and other organs in the body.
The motor tracks in the spinal cord are located in the anterior region, along with the sensory tracks that carry information from the body to the brain. These tracks are organized into columns of neurons called tracts, which are grouped according to the type of information they carry and the areas of the body they serve. Motor tracts carry information from the brain to the muscles and other organs, controlling movements and other functions.
Overall, motor tracks in the spine can be found in the anterior portion of the spinal cord, along with the sensory tracks that carry information from the body to the brain. These tracks are essential for controlling movements and other functions in the body.

Molecular biology, biogeography, comparative anatomy, and the fossil record all provide evidence for common descent, and that modern species have evolved from prior species. By studying these sources, one can gain a better understanding of the evolutionary process, and how species have changed over time.
Molecular biology provides evidence for common descent by comparing the genetic sequences of different species. Genetic sequences are like fingerprints that are unique to each species, and by comparing the genetic sequences of two species, one can determine how closely related the two species are. For example, if two species have similar genetic sequences, then it is likely that the two species are closely related, and are descended from a common ancestor.
Biogeography is the study of the geographic distribution of species. By looking at the geographic distribution of species, one can infer how the species might have evolved from their ancestors. For example, if two species are found in the same geographic area, then it is likely that the two species are related, and descended from a common ancestor.
Comparative anatomy is the study of the anatomy of different species. By comparing the anatomy of different species, one can determine how closely related they are. For example, if two species have similar anatomical features, then it is likely that the two species are closely related, and are descended from a common ancestor.

Describe one struggle a forensic scientist might have when looking at DNA evidence?
The benefit of sketching or providing a screenshot of the DNA fingerprints for qualitative data is the ability to relate an individual to certain genetic features (question 1). The benefit of gathering quantitative data on the base-pair lengths is that we can obtain repeated polymorphisms that may be useful to discover a variation pattern (question 2). Some limitations for a forensic scientist using DNA as evidence are the rapid degradation of this molecule or the presence of identical sequences in different individuals (question 3).

For a given level of ambient light, the central ganglion cells respond proportionally to a small point of light over a range of about one log unit intensity. Through an adaptation mechanism, the ganglion cells in the center can dynamically encode the brightness level in the center in the range of 6 log units of ambient light level.
