Answer:

The Hardy-Weinberg equation can be used to gather valuable information about a population in the following two ways:

1) Estimating allele frequencies: The Hardy-Weinberg equation allows scientists to estimate the frequency of specific alleles within a population. By comparing the observed frequencies with those predicted by the equation, researchers can determine if the population is in genetic equilibrium, meaning that the allele frequencies are stable and not evolving over time.

2) Identifying evolutionary forces: If a population deviates from the expected Hardy-Weinberg equilibrium, it suggests that one or more evolutionary forces, such as natural selection, genetic drift, gene flow, or mutation, are at play. By analyzing these deviations, scientists can gain insights into the factors influencing the genetic makeup of the population and better understand the evolutionary processes driving changes in the population's gene pool.

Explanation:

In the process of photosynthesis, water H₂O supplies the hydrogen(H) used in the formation of glucose.

Photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.

With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter(glucose).

Overall reaction during photosynthesis:

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

Answer:

roughly 90 percent of stored energy is lost as waste heat each time

Answer:

In general, roughly 90 percent of stored energy is lost as waste heat each time you go up the food chain by one trophic level. In other words, animals, on average, convert just 10 percent of the energy available from the organisms they eat into stored chemical energy.

It can show because it can be a recessive trait that can be showed up in ones genes. Recessive traits can be less present in parent parents but if both parents have similar recessive traits it can be able to show up in offspring and future offspring. Also it can show in offsprings because of earlier generations. The parents might not have these traits but grandparents are great grandparents might have the traits.

Answer:

The correct option is the degradation of the transmitter molecules by enzymes.

Explanation:

The key lock system is a type of enzymatic catalysis / anabolization, and is so called because the enzyme that reacts with its substrate is in the male-female or key lock format.

Enzymes can also react by other mechanisms, but this is known for the perfect fit of the substrate with the binding site, since one represents the negative of the other, once joined and the reaction started, the active site is occupied and the enzyme is not reacts with another substrate simultaneously to that one.

Answer:

d. It avoids the depletion of soil nutrients.

Explanation:

Crop rotation is the process of planting different crops in the same area of land in rotation. This allows the breathing of the soil as well as the retention of nutrients in the soil.

Crop rotation is one form of conserving soil as it helps in saving the nutrients of the soil from getting depleted. As different crops require different nutrients, the change in crop plantation between different types of crops help in maintaining the fertility of the land. This way, when crops are planted in rotation, there is also the rotation of the different nutrients required for the different crops planted, thus allowing the cycle of nutrient change to take place.

Thus, the correct answer is option d.

Answer:

Results in the evolution of the species: Directional selection

Results in a new species: Disruptive selection

Favors traits at the two extreme: Disruptive selection

No increase in diversity: Stabilizing selection

One extreme trait is favored: Directional selection

Diversity decreases: Stabilizing selection

Diversity increase: Disruptive selection

Explanation:

Natural selection changes the allele frequency of a gene that produces an inheritable trait

The type of natural selection that takes place can be grouped into three categories based on their effect on allele frequencies including;

Directional selection

Stabilizing selection

Disruptive selection

In directional selection, a particular allele that has a higher fitness naturally increases its frequency in the population such. The process of directional selection is able to progress directionally so as to spread to the entire population

Stabilizing selection involves the reduction of the allele that has a cancelling effect on the desired phenotype and that can result the production of organisms with a fitness reduction. The stabilizing selection process can continue until the elimination of the deleterious allele from within the population

The disruptive selection process takes place between the the period of transition resulting in the alteration of the trait in in more directions than one.

Answer:

Results in the evolution of the species: Directional selection

Results in a new species: Disruptive selection

Favors traits at the two extreme: Disruptive selection

No increase in diversity: Stabilizing selection

One extreme trait is favored: Directional selection

C, Build Breakwaters In The Ocean.

Explanation:

The action that can humans take in order to reduce wave erosion is the building of breakwaters in the ocean. Thus, the correct option is C.

Wave erosion may be defined as the process that may significantly lead to the displacement of land, and the long-term elimination of sediment and rocks along the coastline due to the effective action of waves, currents, tides, wind-driven water, and waterborne ice, or other impacts of storms.

Wave erosion is a problem that may impact aquatic organisms as well. So, in order to reduce such kind of problem, human needs to construct or build breakwaters in the ocean.

The construction of breakwaters in the ocean reduces the loss of land as well as the long-term removal of sediments and rocks.

Therefore, the action that can humans take in order to reduce wave erosion is the building of breakwaters in the ocean. Thus, the correct option is C.

First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.

After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.

After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.

After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".

At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.

The Cretaceous period was a prehistoric period that took place between about 140 and 60 million years ago. If a scientist wanted to use the scientific method to learn more about this time, he should implement the following steps:
