Replicas are repetitions of the basic experiment to get better and more reliable results. 1) 20 pods. 2) 32 plants. 3) By using replicas the researcher gets more representative results, and the experiment is more reliable.  

When talking about replicas in an experiment, we refer to the repetition of the most simple basic element.

Having several replicas in an experiment let the researcher to get more precise results and obtain a better estimation of the experimental error.

The greater the numer of replicas the researcher includes in the experiment, the better and more precise will be the results.

In the exposed example,

1) What is the total number of pots used in this experiment?

Twenty pods in total. Four pods per soil treatment (4 x 5 = 20)

2) How many plants received each soil treatment?

Thirty two plants per treatment. Eight plant per pod (8 x 4 = 32)

3) Why multiple pots and plants were used for each treatment?

Because it provides more reliability to the experiment. These are replicas. They let the researcher know if the result at any of the pods was due to other factors or random chances. Using several pods per treatment increases the chances of getting real results. In this way, results are more representative of what really occurs in nature.

Complete question,

The rhizosphere, the soil layer surrounding plant roots, is a complex community in which archaea, bacteria, fungi, and plants interact with one another.

After plants are attacked by fungal or bacterial pathogens, soil from the rhizosphere may protect plants from future attacks. Such protective soil is called disease-suppressive.

Researchers investigated whether microorganisms were responsible for the protective effects of disease-suppressive soils.

The researchers predicted that soil from the margin would not offer protection against pathogens.

The researchers then planted and raised sugar beets in greenhouses, using 5 different soil treatments,

The pots were inoculated with Rhizoctonia solani and placed in greenhouses kept at 20degree C with a 16-hour light: 8-hour dark cycle.

After 20 days, researchers determined the percentage of infected sugar beet seedlings for each soil treatment.

Low variation. The more time that passes, the extra the wide variety of gathered series differences among two populations. within populations it's miles much more likely that genetic variation in DNA sequences can have quite low variability.

DNA sequencing is the system of identifying the nucleic acid series the order of nucleotides in DNA. It consists of any technique or era that is used to decide the order of the 4 bases: adenine, guanine, cytosine, and thymine.

Each strand is made from a chain of 4 nucleotides, A, C, G, and T. The order of the nucleotide collection encodes genetic facts. since the nucleotides pair in a predictable manner A with T, and C with G each strand of the DNA is generally complementary to the other.

DNA sequencing refers to the overall laboratory technique for figuring out the exact collection of nucleotides, or bases, in a DNA molecule. The sequence of the bases (often cited by way of the use of the primary letters of their chemical names: A, T, C, and G) encodes the organic records that cells use to expand and operate.

The four major cellular processes that are influenced by genes that play a role in development are – cell division, cell migration, cell differentiation and cell death.

Cell division is a cellular process where the parent or mother cell gets divided into two or more daughter cells. Two distinct cell division processes are meiosis and mitosis.

Cell migration is a multifaceted and an evolutionary conserved cellular process responsible for the development and maintenance of organisms. It allows individual cells and cell groups to change positions, move and build and maintain tissues and organs for homeostasis, embryonic development and regeneration.

Cell differentiation is a cellular process caused by changes in the gene expression due to which the dividing cells alters its phenotypical or functional type.

Cell death is an essential cellular process where all the unwanted cells are removed by a programmed process known as apoptosis.

Answer: The significance of molecular polarity to the biological sciences come from two main areas: First, polar molecules tend to become oriented with respect to other molecules. Because of this, polar molecules are important in helping to establish the three-dimensional structure or orientation of other larger molecules.

Explanation:

Answer:

Polar molecules are important in life because they have a positive charge on one end and a negative charge on the other. This means that they attract each other, which is why water has such a strong bond between them. Without polar molecules, there would be no way for water to stick together in order to form ice or snowflakes. Polar molecules also help create the structure of DNA and RNA, which are essential parts of all living things.

Amuvatinib is a brand-new tyrosine kinase inhibitor that can be taken orally and has been shown to be effective against mutant KIT, platelet-derived growth factor receptor alpha (PDGFR), and Rad51 in vitro. Amuvatinib was studied in a first-in-human, single-agent, phase I, accelerated titration, dose-escalation experiment in patients with solid tumours that had shown resistant to prior treatments or for which there was no approved treatment (ClinicalTrials.gov identifier: NCT00894894).

With amuvatinib DPC, administered as a single dosage or in divided doses, for 1-6 cycles, there were no observed toxicities at doses up to 1,500 mg/day. No upper limit of tolerability was reached. Serious side effects that were not connected to the medication occurred in five participants. Low and erratic exposure levels were present. One GIST patient who had previously failed imatinib and sunitinib treatment showed a response on 2-[18F]fluoro-2-deoxyglucose positron emission tomography and had clinically stable illness.

The consumption of large amounts of CO₂ by living trees is thought to make little or no net contribution to the reduction of global warming due to the process of cellular respiration.

In plants, carbon dioxide is taken in from the atmosphere for the process of photosynthesis to occur. This intake of carbon dioxide is however not enough to reduce the effects of global warming because plants also release carbon dioxide during the process of cellular respiration.

Cellular respiration is the process in which the cells make carbon dioxide and water from glucose and oxygen. ATP is produced as a result of cellular respiration which is the driving force for all activities in a cell. Hence, although trees are consuming carbon dioxide during photosynthesis, they are also releasing carbon dioxide during cellular respiration.

When trees die, the decomposition process also releases carbon dioxide into the atmosphere. Hence, the consumption of carbon dioxide is thought to make little or no contribution to global warming.
