Answer:
When making yogurt the tart flavor get in the end is more likely because the bacteria have carried out a type of respiration named lactic acid fermentation (option C).
Explanation:
The process of obtaining yogurt from whole milk involves the association of the bacterial species Streptococcus and Lactobacillus. In order to carry out the lactic acid fermentation that produces yogurt, the bacteria act in a different way:
- Streptococcus is in charge of removing the oxygen from the milk product.
- Lactobacillus promotes the conversion of lactose sugar into lactic acid.
This fermentation process leads to the conversion of milk into a coagulated and tart flavor product.
Other options are not correct because:
<em> A. </em><u><em>Photosynthesis
</em></u><em>: is the process that occurs in plants to obtain chemical energy from sunlight.</em>
<em> B. </em><u><em>Alcoholic fermentation</em></u><em>: in this chemical process alcohol is obtained from the fermentation of a sugar.</em>
<em> D. </em><u><em>Aerobic cellular respiration</em></u><em>: does not involve fermentation, but the series of processes that convert glucose into energy.</em>
Answer:
Gl, gL, GL and gl
Explanation:
The heterozygous parent has the genotype Gl/gL. Since this is a diploid individual, it has two copies of each autosomal chromosome. The slash "/" represents a separation between the two homologous chromosomes, <em>Gl</em> are the alleles of genes "G" and "L" present in one chromosome, and <em>gL</em> are the alleles of those genes present in the other chromosome.
During meiosis the total chromosome number of the original diploid cell is reduced by half, creating four haploid gametes. In a specific stage of meiosis, homologous chromosomes pair and crossing over occurs, when recombination happens and one of the alleles present in one chromosome "switches" to the other chromosome, increasing genetic variation.
<u>Therefore, the Gl/gL individual can produce four different types of gametes:</u>
Gl and gL (Parental --> no crossing over occurred)
GL and gl (Recombinant --> crossing over occurred)
Answer:
D) The encoded protein contains four repeats of a specific sequence.
Explanation:
The polymerase chain reaction is a technique used to replicate or amplify the amount of DNA sample.
The technique employs running the DNA samples on the gel through which the DNA samples run based on their sizes.
The large-sized DNA fragment runs to a less distance whereas the small-sized DNA run to a large distance.
In the given question, four sizes of DNA bands are formed in the ratio of 1:2:3:4 which shows that the proteins encoded by this DNA have four repeats of a specific sequence of the template strand. This was confirmed when the largest band sample was again used as a sample of PCR and the PCR resulted in the four bands in similar 1:2:3:4.
Thus, Option-D is the correct answer.
Anabolic is a chemical reaction that fuses molecules in the body, the process is called anabolism. It is gathering of normally manufactured hormones that are subordinates of testosterone, are utilized therapeutically particularly to advance tissue development, and are once in a while manhandled by competitors to build the size and quality of their muscles and enhance continuance.
Unregulated and uncontrolled cell growth is the most common simple definition of cancer. Because of the many types of cancers and a huge range of possible symptoms, treatments are also very diverse. Type of treatment also depends on cancer stage at diagnosis, and the patient's overall health. Some forms of treatment:
• Chemotherapy-usage of chemicals (medications) that target rapidly uncontrolled dividing cells,
• Hormone therapy
• Immunotherapy-usage of the medications that boost the immune system
• Radiation therapy-usage of radiation to kill the cancer cells
• Surgery
• New approaches such as stem cell therapy or personalized therapy.
