the nontemplate strand of a portion of a gene reads 5'ACTGGTTCA. What will the sequence of the resulting transcript for this portion
Answer:
DNA template sequence:
5' TGACCAAGT 3'
RNA antisense sequence: 3' UGACCAAGU 5'
>>> RNA sense sequence (transcript) : UGAACCAGU
Explanation:
In the DNA molecule, four types of nitrogenous bases are found: cytosine (C), and guanine (G), adenine (A) and thymine (T). In DNA the bases pair up with each other in the following ways: A pairs with T by two hydrogen bonds, while C pairs with G by three hydrogen bonds. In RNA (i.e., transcript sequence), T is replaced by uracil (U). Moreover, the RNA nucleotide sequence is read in the direction 5' to 3'.

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.

what is biodiversity Which of the following shows the correct chronological order (geologically oldest to most recent) of near or total extinctions for the organisms listed?
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.
A graph titled "Average plant height (cm) vs. Concentration of sodium phosphate (mg/L)" shows an upward-sloping line that reaches a maximum value and then stays there over the remainder of the graph.
What noticeable trend from this graph might be used to make a conclusion?
A.
Average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.
B.
Average plant height causes an increase in the concentration of sodium phosphate.
C.
Average plant height is not affected by the concentration of sodium phosphate.
D.
Average plant height is halved every time the concentration of sodium phosphate is doubled until all of the sodium phosphate has been used up.
Answer:
A. Average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.
Explanation:
The graph in the attachment section portrays the average height of plants (cm) on the y-axis plotted against the concentration of sodium phoshate (mg/L) on the x-axis. Based on the observation of the result in the graph, an increase in the concentration of phosphate caused an increase in the average plant height (as depicted by the upward-sloping line).
However, the plant's average height didn't go beyond 35cm despite an increase in concentration of phosphate. This is because the plants has reached a maximum possible height i.e. a height climax. Hence, they cannot grow taller than 35cm no matter the amount of external nutrients (sodium phosphate) supplied.
Therefore, the noticeable trend that can be used to make a conclusion is that average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.

Assuming the population begins in H−W equilibrium, what is C1 allele frequency after one generation of natural selection? Express your answer using three decimal places.
Complete question:
In a population of flowers growing in a meadow, C1 and C2 are autosomal codominant alleles that control flower color. The alleles are polymorphic in the population, with f (C1) = 0.7 and f (C2) = 0.3. Flowers that are C1C1 are yellow, orange flowers are C1C2, and C2C2 flowers are red. A storm blows a new species of hungry insects into the meadow, and they begin to eat yellow and orange flowers but not red flowers. The predation exerts strong natural selection on the flower population, resulting in relative fitness values of C1C1 = 0.30, C1C2 = 0.60, and C2C2 = 1.0. Assuming the population begins in H−W equilibrium, what is C1 allele frequency after one generation of natural selection? Express your answer using three decimal places.

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.
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.
