The erbB2 gene, commonly referred to as HER2 or neu, produces a 185-kDa transmembrane glycoprotein that is a member of the EGFR family of epidermal growth factor receptors. The ERBB2 gene, a transmembrane receptor tyrosine kinase, encodes the human epidermal growth factor receptor 2 (also known as HER2 or HER-2/neu). An intrinsically active receptor tyrosine kinase, ErbB2 functions as a tyrosine kinase.

at short focusing distances, ciliary muscles contract. what effect do these contractions have on the suspensory ligaments?
At short focusing distances, ciliary muscles contract causing the suspensory ligaments to tighten.
The ciliary muscle is an integral muscle of the eye that is constructed as a ring of smooth muscle in the middle layer of the eye, the uvea (vascular layer). It regulates the passage of aqueous humor into Schlemm's canal and governs accommodation for observing objects at different distances.
A suspensory ligament is a ligament that provides support to a body part, particularly an organ. The suspensory ligament protects the fetlock from hyperextension (i.e., falling too low) during exercise. The ligament begins in both the fore and hindlimbs at its connection to the back of the upper cannon bone.
When the ciliary muscle relaxes, its diameter increases; when the suspensory ligaments tighten, the lens becomes thinner. This occurs when concentrating on a celestial object. When the ciliary muscle contracts, the lens becomes much more circular and has more focusing power because the pressure on the zonular fibers is reduced. When the ciliary muscles relax, these fibers contract, pulling the lens out and creating a flatter shape with less focusing power

What Is the Carbon Cycle? Photosynthesis, Decomposition, Respiration and Combustion
In the carbon cycle, carbon dioxide is removed from the atmosphere by plants through photosynthesis and added to the atmosphere by animals and plants during cellular respiration. Burning fossil fuels increases the amount of carbon dioxide released into the atmosphere, which causes global warming. Option (a) is correct.
Thus, carbon can be found in a variety of substances, including coal and the hydrocarbons glucose and carbon dioxide. But today, we'll focus on the short-term carbon cycle, in which carbon simply circulates through the environment over a few days, weeks, or years. Photosynthesis: Process of photosynthesis, using photosynthesis, plants remove carbon dioxide from the atmosphere. Despite making up less than 1% of the atmosphere, carbon dioxide has a significant impact on life.
Nutrient Cycle: Decomposition of Plants can develop primarily by utilizing carbon dioxide, water, and sunlight. Animals then use food as fuel, exhaling CO2 and using oxygen. Alternately, they rot, deteriorate, and die again over the course of millions of years. In other words, through a process called respiration, plants use solar energy to break down the same carbon dioxide in the air. It converts that same carbon into plant material through photosynthesis, which then releases oxygen once more. Combustion, is the energy produced by burning fossil fuels is used by our automobiles. Carbon, like carbon dioxide, is a pollutant. Fossil fuels are extracted, and then they are burned to release energy. But carbon dioxide is returned to the atmosphere as a byproduct of burning.

parent 1 is heterozygous for both the ""a"" and the ""b"" alleles. parent 2 is homozygous recessive for the ""a"" allele and homozygous dominant for the ""b"" allele. what are the possible gametes each parent can produce in regards to these two traits?
If parent 1 is heterozygous for both the "a" and the "b" alleles, this means that they have one copy of the dominant "A" allele and one copy of the recessive "a" allele for the "a" trait, and one copy of the dominant "B" allele and one copy of the recessive "b" allele for the "b" trait.
This means that parent 1 can produce two different types of gametes for each trait: those containing the "A" and "B" alleles, and those containing the "a" and "b" alleles.
Therefore, the possible gametes that parent 1 can produce in regards to these two traits are "A"/"B", "A"/"b", "a"/"B", and "a"/"b".
If parent 2 is homozygous recessive for the "a" allele and homozygous dominant for the "b" allele, this means that they have two copies of the recessive "a" allele for the "a" trait, and two copies of the dominant "B" allele for the "b" trait. This means that parent 2 can only produce gametes containing the "a" and "B" alleles.
Therefore, the possible gametes that parent 2 can produce in regards to these two traits are "a"/"B".
When the gametes from both parents combine during fertilization, there will be four possible combinations of alleles for each trait: "A"/"B", "A"/"b", "a"/"B", and "a"/"b".

how could dna extracted in these procedures be amplified for further analysis in a biomolecular laboratory. explain the polymerase chain reaction in your answer.
The copying process, known as polymerase chain reaction (PCR), uses an enzyme (polymerase) to replicate DNA regions in a test tube. By repeating the copying process, a small number of DNA molecules can be reliably increased up to billions within several hours.
When Dr. Kary Mullis found that DNA could be replicated in a lab much like it is in the natural world, DNA testing advanced substantially.
An enzyme (polymerase) is used in the polymerase chain reaction (PCR), a copying procedure, to replicate DNA sections in a test tube. A modest amount of DNA molecules can be reliably multiplied by billions in a matter of hours by repeating the copying process. A biological sample the size of a quarter is needed for RFLP analysis, while millions of copies of the DNA found in a few skin cells can be produced using PCR. The laboratory may be able to evaluate DNA evidence that has been severely damaged because PCR analysis only needs a tiny amount of DNA. While identifying, gathering, and preserving DNA evidence, more consideration must be given to contamination issues because the sensitive PCR technology replicates all DNA present in an evidence sample. Heat is applied at the beginning of the procedure to separate the DNA strands from the initial double-stranded DNA molecule, creating templates for each stand.
The complementary strand is subsequently created by the Taq DNA polymerase using nucleotides after primers have been added to the template strand. Since Taq polymerase can endure high temperatures, it is specially used. An extension is a procedure by which additional nucleotides are added, whereas annealing is the procedure by which primers are joined to the DNA strands.

How does crossing over lead to genetic variation ?
Genetic data is transferred between homologous chromosomes during crossing over. Through this exchange, novel gene combinations are formed, increasing the genetic diversity of the progeny.
Homologous chromosomes (one from each parent) pair along their lengths during meiosis. Chiasma points are where the chromosomes cross. The chromosomes split and reassemble at each chiasma, swapping some of their genes. Genetic variety is produced by this recombination. The exchange of genetic material between non-sister chromatids of homologous chromosomes, or crossing-over, takes place during prophase I. Remember that homologous chromosomes align in pairs, gene for gene down their whole length, generating a configuration with four chromatids known as a tetrad during prophase I.
A new mix of genetic data for the cell for a particular trait results from crossing over. By crossing over, organisms are prevented from being genetically identical from generation to generation. Variations in the genetic material that is passed down through the generations are made possible via genetic recombination. To boost genetic variety, chromosomes that are similar to one another cross across. A piece of one chromosome is swapped for another during crossing over. A hybrid chromosome with a distinctive genetic material pattern is the end outcome.
