Answer:
DNA strand: 5' TTC CAT GGA 3'
RNA strand: 3' AAG GUA CCU 5'
Explanation:
From the DNA template, an RNA molecule will be transcribed that is single stranded. So, it will read off the code from the 5' to 3' strand of DNA to create the RNA molecule made of complementary bases, in triplet codons. The enzyme that carries out this function is RNA polymerase.
Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: Estrogens from the vesicular follicle trigger an LH surge from the anterior pituitary. This is an example of: negative feedback first tier of control positive feedback fourth tier of control
Answer:
The correct answer is: positive feedback.
Explanation:
Positive and negative feedback are terms that are used to define the way a system is regulated by its products. For example, when the production of a certain substance inhibits its producer that is called negative feedback. On the other hand, when a substance stimulates its producer to keep secreting said substance, this is called positive feedback.
Estrogen is a hormone of great importance in the female reproductive cycle and is secreted by the follicle cells in response to the presence of FSH (follicle-stimulating hormone), released by the anterior pituitary when stimulated by the GnRH (gonadotropin-releasing hormone).
Estrogen appears at the beginning of the cycle to stimulate the development of the ovarian follicles, and the hormone levels continue to rise as the cycle advances. Up until the 14th day of the cycle, estrogen has a negative feedback on GnRH and FSH, but then it makes an abrupt change to now exert positive feedback on GnRH to stimulate the release of LH (luteinizing hormone), which will be responsible for ovulation.
The amino acid methionine is specified by the codon 5'-AUG, and a methionine tRNA can have the anticodon sequence 5'-CAU. Which of the following is the base sequence of the template strand of the part of the tRNA gene corresponding to the anticodon?
a. 5'-GTAb. 5'-CAUc. 5'-CATd. 5'-UACe. 5'-AUGf. 5'-GUAg. 5'-TACh. 5'-ATG
Answer:
g. 5' GUA
Explanation:
Because it is a reverse start codon to the 5'-AUG. Template stands and coding strands have the reverse of each other
A-T(DNA), A-U (RNA), G-C
Hope this helps.
The base sequence of the template strand of the part of the tRNA gene corresponding to the anticodon is 5'-GUA. So, the correct option is F.
What is a Template strand?Any strand which is used by DNA polymerase/RNA polymerase to attach a complementary base during DNA replication/RNA transcription. It provides an idea for replication.
The amino acid methionine is specified by the codon 5'-AUG, the template strand of the part of the tRNA gene is a reverse of the start codon. Template stands and coding strands are complementary to each other in such a way as to facilitate the process of DNA replication or RNA transcription.
Therefore, the base sequence of the template strand of the part of the tRNA gene corresponding to the anticodon is 5'-GUA.

as an aspiring nurse,the need for the culture of a new pathogenic microorganism in the laboratory has been allocated to you. Applying all the guidelines involved in the successful isolation and cultivation of microbes, discuss the culturing system that is most appropriate for this activity and state your reasons for this choice
Answer:
The culturing system depends on the sort of microbe allotted to segregate namingly bacteria, viruses, or fungi. Each microbial pathogen has particular culture media for disconnection and for development or replication, we need culture media.for model bacterial pathogen can be separated by plating the example in fitting media by 3 strategies that are streak plate or pour plate or spread plate
Out of the above streak, plate gives the best outcomes in single disengaged provinces which can be additionally cultured and characterized for creation of pure culture

Write down the oxygen requirements of the microorganisms growing in thioglycolate tube.
Answer:
Obligate aerobic microbes requires oxygen for its survival in the thioglycolate tube while Obligate anaerobic microbes does not requires oxygen.
Explanation:
Thioglycolate tube is a tube which is used to determine the oxygen requirement of different types of microbes. The concentration of oxygen is higher in the upper portion of the tube while in the lower portion, the concentration of oxygen is the lowest. So those microbes who needs oxygen for their survival will be present in the upper portion of the tube while those microbes who does not need oxygen, will be present at the bottom of the tube.

Schilders disease is a progressive degeneration of the central nervous system that leads to death by age 2. The disease is caused by a simple autosomal recessive mutation. A couple loses its first two children to Schilders disease. If they decide to have a third child, what is the probability that it will have the disease
Answer:
The probability will be 25% (1/4)
Explanation:
Schilder's syndrome is a degenerative and progressive lethal disease caused by the demyelination of nerve cells in the brain and spinal cord. Since it is a lethal recessive autosomal disease, both the father and the mother have a single copy of the mutant allele, thereby the probability of obtaining a lethal combination will be:
SN X SN >>
1/2 x 1/2 = 1/4 = 25%
where N and S are normal and lethal alleles, respectivelyvely

Why are scientists studying the effects of warming on boreal forests? How far might this forest biome move if climate projections are correct?
Answer:
Scientists studying the effects of warming on boreal forests which change the biome.
Explanation:
The main effect of warming on boreal forests is to change the biome because the plants and animals will not tolerate the increased temperature which occcurs due to climate change so the plants and animals disappeared from the boreal forests and change its biome. The animals migrated to other suitable environment where they continue its growth and increase their population. If climate projections are correct, the biome of this forest go to those places where the environment is suitable.

How could you use different research methods to complement each other when studying a particular process in the brain?
Answer is given below
Explanation:
The brain is a complex structure and requires different methods to be declared in order to obtain a clear illustrator. Cavalder study is a method of comparing the brain of a dead person. For example, Einstein compared the brain to the brain of ordinary people. It has been hypothesized that the proportion of glia cells in the neuron is higher in a person with a higher IQ, such as Einstein. However, it cannot be confirmed that only a specific brain is available. The study of the session helps us to identify the problem associated with defects in a particular area and eliminates the function of a specific area of the brain. For example, clots form in the frontal lobe during a stroke, which can sometimes lead to epilepsy. The disadvantage of these methods is that the brain is not active. A new method of EEG electroencephalogram that measures electrical signals if each neuron is present. It measures brain activity when the brain is active. The EEG can provide information about the normal patterns of electrical activity in the brain, and although the EEG allows the researcher to quickly observe when these changes occur in real time, the electrode measures the surface of the skull and each electrode measures brain waves from large areas to be placed on the brain. EEGs do not provide a very clear picture of brain structure. The image of the brain cannot be obtained by changing the electrode to measure the electrical signal. but there are MRI techniques to provide more specific brain images. Functional magnetic resonance imaging uses the scan method using magnetic fields to create an image of the brain in each activity field. Therefore all mixed methods can help to study the brain and related activities more deeply and effectively.Answer:
Brain is a complex structure and needs analgamation of various methods to get a clearer picture.
One method is cavalder studies where brains of dead person is compared. For instance , Einstien brain was compared with ordinary people brain. The ratio of glia cells to neuron was hypothesised to be higher in high IQ person such as Einstien. However , this cannot be ascertained as only one special brain was available.
Lession studies help us identify the problem associated with a lession in a particular area and conclude the function of specific region of brain.for example , during stroke the is clot in frontal lobe that leads to epileptic ceasure sometimes.
Drawback of these method is that brain is not active. So new method of EEG electro encephelogram which measure electrical signals if each neuron. It measures brain activity when brain is active.
the EEG can provide information about the general patterns of electrical activity within the brain, and although the EEG allows the researcher to see these changes quickly as they occur in real time, the electrodes must be placed on the surface of the skull and each electrode measures brain waves from large areas of the brain. As a result, EEGs do not provide a very clear picture of the structure of the brain. A still images of brain cannot be obtained by placing electrodes to measure electrical signal.
But MRI techniques exist to provide more specific brain images. Functional magnetic resonance imaging uses a scan method utilising magnetic field to create an image of brain in each activity area.
Thus all methods combined can help in study of brain and associated activities more profoundly and effectively.

Draw a flow chart of the steps that would be employed by a neutrophil to eliminate a bacterial cell. Assume that no antibodies are present that recognize the bacteria as foreign.
Answer:
The neutrophil is the first line of defense, it is called as PMN OR POLYMORPHONUCLEAR NEUTROPHIL, this cell is said to be the first line of defense for the first to reach the area of infection or in the area of trauma, this upon reaching that area (where it is attracted by defense chemomodulators) it recognizes the bacteria or the foreign body as an antigen, since these do not present the cellular histocompatibility complex of our organism, by recognizing it as an antigen, this cell can detect that it is not something typical of our body but something new that was inoculated, is how this phagocyte to the bacteria and induces its own programmed cell death.
In an injury or infection, the purulent collection is not only debris and pathogenic microorganisms, but they are dead cell bodies of PMNs that induce their own cell death with the battery inside to be able to inhibit its advance in our body, when this phenomenon passes the PMN it is called a peach.
Explanation:
In the event that no antibodies are present, it would not change much if it is the first time that the bacteria enters our body since the formation of antibodies by the lymphocyte cell line occurs as the last stage of immunity (neutrophils appear first, then the antigen presenting cells and finally the lymphocyte lineage in charge of making immunological memory with antibodies).
The PMN are guided more than anything by the humoral factor of the immune response, but the proinflammatory factor like cytokines or leukins, but not by the antibodies, that is why he wrote this process of bacterial assimilation in the response.

Answer:
Biodiversity is the diversity of living beings, be they animals or plants, which together make up the totality of life on planet Earth. In other words, the term biodiversity necessarily implies a large number of different species and genres of living beings, which interrelate with each other through food chains, sharing natural habitats or even establishing more complex links. In any case, it requires that heterogeneity that implies the existence of several different living beings from each other in a given space.
