The air move counterclockwise and anticlockwise due to Coriolanus effect.
Describe the Coriolanus effect?Due to Coriolanus effect, air move to rotate counterclockwise at the large-scale low-pressure systems and move clockwise at large-scale high-pressure systems in the Northern Hemisphere while on the other hand, the air rotate counterclockwise at the large-scale high-pressure systems and move clockwise at large-scale low-pressure systems in the Southern Hemisphere
So we can conclude that air move counterclockwise and anticlockwise due to Coriolanus effect.

What causes earthquakes?
How are earthquakes measured and how big can they get?
Explanation:
Earthquakes are caused by friction at the ends of tectonic plates. WHen they become stuck at their edges from this friction, stress builds up,, and eventually overcomes the friction, becoming an earthquake. Earthquakes are measured on the Richter scale. The largest earthquake ever documented was 9.5 in Chile on May 22nd, 1960.

Name three methods of disrupting cells before fractionation
Extraction, homogenization, and centrifugation are the three processes in cell fractionation.
Cell fractionation is a method for dividing cellular components while yet maintaining each component's unique functionality. This technique was initially applied to show where distinct biochemical activities are located within cells. Subcellular fractionation is also used to help with illness detection and to offer an enhanced source of protein for further purification. To prevent osmotic damage, tissue is routinely homogenized in an isotonic buffer solution. Grinding, mincing, chopping, pressure changes, osmotic shock, freeze-thawing, and ultrasonic waves are a few of the mechanisms for homogenization. After that, the samples are maintained cool to avoid enzymatic deterioration. It is the development of a uniform mass of cells (cell homogenate or cell suspension).

how is the process of photosynthesis taking place thru Calvin Cycle?
This is the ideal question! Thanks for asking!
Before we start, let's go through a mini-review.
Photosynthesis:
The complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates by green plants, algae, and certain bacteria, using energy from the sun and chlorophyll.
Calvin Cycle:
A series of biochemical reactions that take place in the stroma of chloroplast in photosynthetic organisms.
Now that we have gone through what these two terms are and their definitions, let's head onto the actual questions.
So the question asks, how is the process of photosynthesis taking place through Calvin Cycle?
In plants, carbon dioxide (CO2[tex]CO2[/tex]CO2C, O, start subscript, 2, end subscript) enters the interior of a leaf via pores called stomata and diffuses into the stroma of the chloroplast—the site of the Calvin cycle reactions, where sugar is synthesized. Because they are not primarily fueled by light, these reactions are often known as the "light-independent reactions."
Carbon atoms from CO2 [tex]CO2[/tex] CO2 C, O, start subscript, 2, and end subscript are fixed (incorporated into organic molecules) and utilized to create three-carbon sugars in the Calvin cycle. ATP and NADPH produced by the light reactions are used to power and support this activity. Calvin cycle reactions occur in the stroma, as opposed to light reactions, which occur in the thylakoid membrane (the inner space of chloroplasts).

D. Decreasing the pH, making it less acidic.
You will run and breathe heavily for a long period of time. is affecting your pH levels, Lowering the pH, making it more acidic.
A. Lowering the pH, making it more acidic.How does respiratory rate affect pH?When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.
With this information, we can conclude that By eliminating carbon dioxide during expiration, pulmonary ventilation reduces the acidity of the blood, helping it to maintain the desired alkalinity level.

Assume N =normal pigment allele;n =Albinism allele (complete absence of brown pigment) if both the parents are heterozygous for albinism ,which allele/s would their gametes have?
The gametes will carry all types of alleles ie, NN, Nn and nn.
Melanin, the pigment that gives skin, hair, and eyes their colors, is affected by albinism. The condition is permanent, yet it does not deteriorate over time. Melanin levels in albinos are either very lower or absent altogether. Their eyesight and coloration may be impacted by this.Albinism follows Recessive autosomal inheritance This means that in order to be born with albinism, a kid must inherit two copies of the allele—one from each parent—from both parents. If both parents have the gene, their child has a 1 in 4 chance of having albinism and a 1 in 2 chance of having the gene.Two heterozygous parents will have gametes Nn and Nn
Nn X Nn (parents)
NN, Nn, Nn, nn (offspring)
Thus, The gametes will carry all types of alleles

Be aware that this outcome supports Mendel's Law of Independent Assortment. The cross is therefore Cc Vv x Cc Vv. II. A quarter of all offspring for two heterozygous parents (Aa) should exhibit the albinism recessive trait.
When two heterozygotes are crossed, the expected genotype ratio is 1 (homozygous dominant): 2 (heterozygous): 1. (homozygous recessive). When a phenotypic ratio of 2:1 is seen, a deadly allele is presumably present.
There will often be 25% YY, 50% YG, and 25% GG offspring if both parent plants have the heterozygous (YG) genotype. These percentages are calculated using the fact that each of a Punnett square's four offspring boxes contains a percentage of 25%. (1 out of 4). In terms of phenotypes, only 25% of individuals will exhibit G. Every time a new child is born to parents with YG genotypes, these are the odds.
Punnett square demonstrates that the offspring probabilities are 25% YY, 50% YG, and 25% GG when both parents are heterozygous.

If you added 1 ml of an aqueous solution of NaCl at 0.4 mol/l to 9 ml of water, what would be the final concentration of NaCl in the solution?
Taking into account the definition of dilution, the final concentration of NaCl in the solution is 0.04 mol/L.
DilutionWhen it is desired to prepare a less concentrated solution from a more concentrated one, it is called dilution.
Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
Ci: initial concentrationVi: initial volumeCf: final concentrationVf: final volumeFinal concentrationIn this case, you know:
Ci= 0.4 mol/LVi= 1 mLCf= ?Vf= 1 mL of aqueous solution of NaCl + 9 mL of water= 10 mL solutionReplacing in the definition of dilution:
0.4 mol/L × 1 mL= Cf× 10 mL
Solving:
(0.4 mol/L × 1 mL)÷ 10 mL= Cf
0.04 mol/L= Vf
In summary, the final concentration of NaCl in the solution is 0.04 mol/L.

The Steady State Theory state that the density of the universe was remaining constant.
Steady State Theory:In cosmology, a steady-state theory is a perspective that holds that the universe is constantly expanding while maintaining a constant average density. According to this theory, the matter is continuously created to form new stars and galaxies at the same rate that older ones fade away due to their expanding distance and accelerating recession. The average density and configuration of galaxies are the same as any location in a steady-state universe, which has no beginning or end in time.
British scientists Sir Hermann Bondi, Thomas Gold, and Sir Fred Hoyle first proposed the hypothesis in 1948. Hoyle expanded on it in order to address issues that had come up in relation to the alternative big-bang theory. According to the hypothesis, in order to maintain a constant average density of matter across time, the new matter must constantly be created, primarily as hydrogen. With nearly five times as much dark matter, the amount needed is small and not immediately observable: one solar mass of baryons per cubic megaparsec every year, or one hydrogen atom per cubic meter every billion years.
