Explanation:

the journalist already has an opinion on the matter, and only uses sources that confirm his opinion and ignores anything that says he is wrong. His bias affects his findings.

Based on this information, the organisms that can produce offspring that are genetically identical to the parent organism are ferns only. The correct option is A.

The generation of descendants is reproduction. Asexual reproduction and sexual reproduction are the two main types. An organism that reproduces sexually incorporates the genetic material from both of its parents and is genetically distinct.

Asexual reproduction creates genetically identical kids by having one parent replicate itself. The generation of plants that we recognize as ferns or horsetails are sporophytes.

Typically, the summer is when the sporophyte releases its spores. For spores to germinate and develop into gametophytes, they need to land on a suitable surface, like a damp, protected place.

Therefore, the correct option is A. Ferns only.

Explanation:

Answer:

incorrect

Explanation:

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders affecting children. ADHD is characterized by different behaviors that include one or more of the following symptoms: inattention (poor concentration), impulsivity (interrupting behavior) and hyperactivity (state abnormally active). It has been reported that DHD diagnoses in children between 4 and 17 years of age dramatically increased from 6 percent (6%) during the period 1997-1998 to 10 percent (10%) during the period 2015-2016. Although the causes of this increase have not been established, the American Psychiatric Association (APA) indicates that the increase might be due to the increased access of communities historically relegated to receive care and decreased stigma to be diagnosed with ADHD. Other possible causes range from chemical factors to unhealthy habits during pregnancy (e.g., smoking, substance abuse, poor nutrition). On the other hand, it has also been proposed that this increase may be as a result that ​ADHD is often misdiagnosed and confused with other conditions (e.g., bipolar disorder, autism, kids being kids, etc).

Answer:

Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion.

Explanation:

Tonicity is the relative amount of solutes that is dissolved in solution which determine the direction and level of diffusion. There are three types of tonicity i.e. hypertonic, hypotonic and isotonic solution. If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink due to more solute in the external environment. In an isotonic environment, there is no water movement occurs, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell. due to lower amount of water present inside the cell.

Answer:

Explanation:

Given that:

The dilution rate D = 0.28 h⁻¹

The concentration of lactose in the feed [tex]S_o = 2.0 \ g/L[/tex]

The effluent S = 0.10 g/L

Also;

[tex]Y_{X/S} = 0.45 g\ X/g \ S , \\ \\ Y_{X/O2 }= 0.25 g \ X/g \ O2, \\ \\[/tex]

Saturation C* = 8 mg/l

To calculate the steady-state biomass, we use the formula:

[tex]X = Y_{X/S}(S_o-S_e) \\ \\ X = 0.45(2.0 -0.10) \ g/L \\ \\ X= 0.45 (1.9) \ g/L \\ \\ X = 0.855\ g/L \\ \\ X = 855 \ mg/L[/tex]

The biomass is 0.855 g/L

For a steady-state condition, the oxygen uptake rate can be illustrated by using the formula:

[tex]q_{o_2}X =\dfrac{\mu_X}{Y_{X/O_2}}[/tex]

where;

[tex]\mu =[/tex] dilution rate (D)

Thus, the steady-state can be expressed as:

[tex]q_{o_2}X =\dfrac{D}{Y_{X/O_2}}[/tex]

[tex]q_{o_2}X =\dfrac{0.28}{0.25}[/tex]

[tex]q_{o_2}X =1.12 \ h^{-1}[/tex]

The specific rate of oxygen consumption [tex]q_{o_2}X =1.12 \ h^{-1}[/tex]

b)

In the fermentation medium, if the desired DO concentration [tex]C_L[/tex] = 2 mg/L

Here, the oxygen transfer is regarded as the rate-limiting step.

As such, the oxygen transfer rate(OTR) is equivalent to the oxygen uptake rate.

In this scenario, let's determine the oxygen transfer coefficient [tex](K_{La})[/tex] by using the formula:

[tex]OTR = K_{La}(C^* - C_L)[/tex]

where;

[tex]K_{La}[/tex]= coefficient of oxygen transfer

C* = saturation

Since [tex]OTR = q_{O_2}X[/tex]

[tex]q_{o2}X = K_{La}(C^*-C_L) \\\\ (1.12 )(855) = K_{La}(8-2) \\ \\ 957.6 = K_La (6) \\ \\ K_{La}= \dfrac{957.6}{6} \\ \\ K_{La} = 159.6 \ h^{-1}[/tex]

Thus, the oxygen transfer coefficient [tex]K_{La}[/tex] = 159.6 h⁻¹

Answer: evaporation, ice melting, precipitation, and ice formation.

Explanation:

Salinity refers to the amount of salt water that can be found in a body of water.

It should be noted that the salinity of a water body can be affected by evaporation, ice melting, precipitation, and ice formation.

The salinity of seawater can be increased through evaporation due to the fact that when the water evaporates, this will lead to the salts being left behind, and this will then increase the salinity.

Answer:

Metallic structure with black colour body.

Explanation:

The substance has metallic structure and black colour body will have greatest temperature among other substances because metallic structure and black colour of body heat up very quickly. Metals have free electrons which make it the best conductor of electricity and heat while on the other hand, black colour is a good absorbent which absorb heat very quickly so that's why we can say that metallic solids are the substance that have the greatest temperature.

Answer and Explanation:

To promote a good DNA extraction through the Chelex extraction protocol, it is important to follow some measures, which are essential for the entire process to take place efficiently.

The most important measure is to avoid contamination. In this case, all surfaces, container and substances used must be properly sterilized, preventing unnecessary elements from coming into contact with the DNA sample or the protocol reagents.

It is important that the researcher is wearing clean, appropriate clothing and gloves when using this protocol. This avoids impurities and contamination with the researcher's DNA.

Another precaution must be taken with the DNA sample and the reagents that will be used during the extraction. All must be stored correctly, preventing their degradation, especially the DNA, which is a very unstable molecule.

Finally, the researcher must strictly follow all the steps of the protocol as indicated.

Answer:

The cell theory  

Explanation:

The modern cell theory states that 1-all living things are composed of cells, 2-all cells derive from pre-existing cells by cellular division, and 3-the cell is the structural and functional unit of all life forms. Many researchers contributed to the development and formulation of the modern cell theory. First, the invention of the optical microscope, followed by the improvement with lighting by Robert Hooke (1660) and observation of microscopic organisms by Antonie van Leeuwenhoek (1675) contributed to the observation of cellular structures that previously were unknown. Subsequently, the cell theory was proposed by Schleiden and Schwann (1839) who suggested that all life forms are composed of cells (the fundamental unit of life). Subsequently, the theory was expanded by Virchow (1855) who proposed that all cells arise from pre-existing cells. Thus, the modern cell theory is the result of the scientific work of many researchers that have contributed across centuries in order to collect a body of knowledge (both experimental and observational) that supports the statements resumed in this theory. Nowadays, it is impossible to conceive biology as a scientific discipline without making reference to the modern cell theory.
