Zonation in lakes and oceans to their correct targets on the diagrams is as :

A: Freshwater plants may be rooted here

B: Littoral zone

C: Limnetic zone

D: Alternately dry and submerged

E: Extends to edge of the continental shelf

F: Generally low nutrient levels

G: Light penetrates here

H: No photosynthesis occurs here

I: Benthic zone

The lake is divided into zones that separate the water from top to bottom. Littoral zone, limnetic zone, profundal zone, euphotic zone, and benthic zone are the zones.

Every pond or lake has several zones that separate the water section from top to bottom and side to side. The Littoral Zone, Limnetic Zone, Profundal Zone, Euphotic Zone, and Benthic Zone are among these zones.

Since the water temperature affects its density, lakes frequently develop layers of varying density that correspond to temperature distinctions across the layers. All but the shallowest lakes in temperate latitudes develop density stratification during spring, which typically lasts until late fall.

If matings are not random in a population and individuals mate with other individuals of similar genotype/phenotype, h0m0zyg0us frequencies increase. In this example, the genotype frequency for Mm is F(Mm) = 0.25.

---------------------------------

In the exposed example, one of the assumptions of Hardy-Weinberg equilibrium is not accomplished. There are non random matings.

Individuals mate with other snails of the same genotypes

MM  x  MM

Mm  x  Mm

mm  x  mm

We can assume this is an example of matings by similar phenotypes.

Eventually, this mating system leads to an increase in the h0m0zyg0us genotype frequency, at the expense of heter0zyg0us ones in loci that determine the trait.

Allelic frequencies do not change. Only genotypic frequencies do.

This mating system tends to separate the population into two subgroups, decreasing the amount of heter0zyg0us individuals.

          Matings              Progeny                              

Zygotic population of the next generation

So, in the exposed example we know that the frequency of the dominant allele M is 0.5

f(M) = p = 0.5

knowing that p + q = 1, we can clear the equation to get the frequency of the recessive allele.

p + q = 1

0.5 + q = 1

q = 1 - 0.5

q = 0.5

f(m) = q = 0.5

Zygotic population of the next generation

       F(MM) = p² + 1/4 (2pq)

       F (MM) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125

       F(MM) = 0.375

        F(Mm) = 1/2 (2pq)

        F(Mm) = 1/2 (0.5)

        F (Mm) = 0.25

        F(mm) = q² + 1/4 (2pq)

        F(mm) = 0.5² + 1/4 (2 x 0.5 x 0.5) = 0.25 + 0.125

        F(mm) = 0.375

The expected genotype frequency for Mm individuals in this population is F(Mm) = 0.25.

Best description of the roots of the equation x² - 4x + 4 = 0 is that it has one real double root.

In mathematics, discriminant of a polynomial is a quantity that depends on coefficients and allows deducing some properties of roots without computing them.

Discriminant is b² - 4ac for a quadratic equation in the form ax² + bx + c = 0. For the equation x² - 4x + 4 = 0, a = 1, b = -4, and c = 4, so the discriminant is: b²-4ac = (-4)²-4(1)(4)

=16 - 16 = 0.

As the discriminant is equal to 0,  quadratic equation has only one real root. This root is a double root, meaning that it is same value twice. In this case, quadratic equation x² - 4x + 4 = 0 can be factored as (x - 2)² = 0, so  only real root is x = 2, and it has a multiplicity of 2.

Therefore, the best description of the roots of the equation x² - 4x + 4 = 0 is that it has one real double root.

The attentional spotlight refers to the idea that attention is like a spotlight that can be focused on a particular object or location, allowing us to selectively process and attend to relevant information while ignoring irrelevant information. It is related to divided-attention tasks because of how attention can be selectively directed to different stimuli or sources of information

Divided-attention tasks are tasks that require individuals to attend to multiple streams of information or stimuli simultaneously. These tasks can be challenging because attention is a limited resource, and dividing attention between multiple sources of information can lead to errors and decreased performance.

The attentional spotlight is related to divided-attention tasks because it illustrates how attention can be selectively directed to different stimuli or sources of information. When individuals are engaged in divided-attention tasks, they may need to shift the attentional spotlight rapidly between different sources of information in order to effectively process and attend to all relevant information.

Multiple Sclerosis

Explanation:

Multiple sclerosis (MS) is the most common neurodegenerative and demyelinating inflammatory disease in adults between 18 and 35 years of age and is the second leading cause of neurological disability in young adults. This pathology is considered an organ-specific autoimmune disorder, characterized by multiple focal areas of demyelination called plaques or lesions, which are accompanied by different degrees of gliosis, inflammation and neuroaxonal damage. It usually manifests itself in coordination and balance problems, muscle weakness, difficulties in thinking and memorizing and sensations of numbness, as well as other symptoms. Diagnosis of MS is based on a clinical evaluation in which all symptoms, as well as the signs (overactive reflexes, incoordination, weakness of specific muscle groups, etc.) of the disease are documented. Magnetic resonance imaging (MRI) is used to obtain cross-sectional images of the brain and spinal cord, which can detect the small areas of inflammation and scarring in the brain typical of MS.Lumbar puncture is an analysis of a sample of cerebrospinal fluid (CSF), which has the function of cushioning the brain and spinal cord, to evaluate the abnormalities that occur in patients with MS. The most common CSF abnormality found in 80-90% of MS patients is an increase in the number of cells and proteins of the immune system (immunoglobulins), suggesting inflammation or a strong immune response. This test is particularly useful to diagnose patients who experience a slow and progressive decline in their functions without exacerbation pictures; that is, people with primary progressive multiple sclerosis, especially when no abnormalities are detected in the MRI images of the brain. CSF evaluation can also be used to exclude infections difficult to distinguish from multiple sclerosis.

The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).

Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.

During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.

The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.

In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.

Competition leads to differential survival and reproductive success among individuals.

Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.

These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.

Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.

Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.

Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.

Line-graphs are used to express how changes in the recorded data occur through time or distances. In the exposed example, it would be best to use a line-graph to visualize how the actual temperature changed from 1900 to 2025.

Line graphs are representations of how the recorded data changes through time or distance. These graphs are used to show events that change in a continuous interval or time-lapse. They allow analyzing how these changes occur.

This representation is set in a cartesian graph, placing one of the variables on the horizontal axis and the other variable on the vertical axis. Usually, time or distance (the continuous variable) is placed on the X-axis, while the associated variable is placed on the Y-axis.

Dots are drawn in the intersection between the two variables, and a continuous line is drawn joining these dots to show the change of values between time (or distance) intervals.
