Answer:

Natural selection is a process where the environment changes and populations have genetic variation, leading nature to select organisms with advantageous traits for survival and reproduction.

Explanation:

Complete sentences:

The environment needs to change in order for natural selection to occur because different traits may become advantageous or disadvantageous in different environmental conditions, leading to differential survival and reproduction.

Populations have some genetic variation, meaning that individuals within a population differ in their traits, including physical, behavioral, and physiological characteristics.

Nature selects organisms with specific traits to survive and reproduce based on their ability to adapt to the environmental conditions and compete for resources, leading to the accumulation of advantageous traits over generations.

A severe drought in the Georgia marshland ecosystem would have a significant impact. It would lead to reduced water availability, affecting the marsh plants, invertebrates, fish, and bird populations, disrupting the food web and potentially causing population declines and habitat loss.

One of the primary effects of a drought is the reduction in water availability. The marshland ecosystem relies on a delicate balance of saltwater and freshwater, which supports the unique plant and animal species found there.

With reduced water availability, the water levels in marshes would decline, leading to increased salinity and changes in the vegetation composition. Marsh grasses and other wetland plants may struggle to survive, affecting the primary producers in the food web.

The decrease in primary producers would cascade through the food web. Herbivores, such as marsh rabbits or marsh snails, may experience food shortages and face population declines.

This, in turn, would impact predators such as marsh hawks or alligators that rely on these herbivores as their prey.

As the population of higher trophic-level organisms decreases, it can disrupt the entire food web, affecting the stability and biodiversity of the ecosystem.

Furthermore, drought-induced habitat changes may force certain species to migrate or seek alternative resources, potentially leading to increased competition for limited food and space. This competition can further disrupt the balance of the food web.

In summary, a severe drought in the Georgia marshland ecosystem would result in reduced water availability, changes in vegetation, and disruptions in the food web.

The impacts would be felt across trophic levels, affecting primary producers, herbivores, and predators, and potentially leading to population declines and alterations in species interactions.

Answer:

The electron transport chain (ETC) is a series of protein complexes located in the inner membrane of the mitochondria that transfer electrons from electron donors to electron acceptors via redox reactions. As a result of the ETC, a proton gradient is formed across the inner mitochondrial membrane, which drives ATP synthesis by the enzyme ATP synthase. The ATP produced through oxidative phosphorylation is the primary energy source for most cellular processes.

Explanation:

The electron transport chain (ETC) is the final step of aerobic cellular respiration and is where the majority of ATP is generated. As electrons move through the ETC, they release energy that is used to pump hydrogen ions across the inner mitochondrial membrane, creating an electrochemical gradient. This gradient powers ATP synthase, which generates ATP by adding a phosphate group to ADP. In summary, the electron transport chain results in the production of ATP, which is the primary source of energy for cellular processes.

Answer:

The three variables which influence our day by day food decisions are cost, a monetary factor; abilities or time, a physical factor; stress or state of mind, a psychological factor.  

At the point when the pay is less or the expense of food is more the day by day food decision is influenced. So by accomplishing the additional work to gain more cash and dependent on picking the food which costs less, every day food decisions can be made.  

At the point when the aptitudes of planning food isn't sufficient and an opportunity to set up the food is extremely less, the day by day food decision is influenced. So by improving the aptitudes of getting ready food with the assistance of cooking classes and books and by overseeing time, to give sufficient time for planning food a negative result can be transformed into a positive result.  

When there is an adjustment in temperament because of part of worry there is a negative result on every day food decision. So by changing the disposition and expelling a ton of worry by tuning in to some otherworldly messages and tunes, the negative result can be changed into a positive result on every day food decisions.

Here, the hypothesis is "plants communicate with their neighbors in response to stress", dependent variable is the amount of the stress hormone in the plants, and the independent variable is the exposure to stress (applied 3 times a day for 10 days), standardized variables are plants used, duration of the stressor, amount of stress hormone. The control group is the plant that is not exposed to stressor.

Here, the control group is the group of plants that are not exposed to stress, and the control groups plants are experimented or tested with the other plants to get the result of the stress hormone on the plants.

Photosynthesis occurs in two stages, light-dependent and light-independent reactions. This last one is the Calvin cycle, and its main function is to produce sugars. D. to produce glucose.

Photosynthesis involves two stages: light-dependent and light-independent reactions.

Light-independent reaction is known as the Calvin cycle, and it takes place in the stroma.

During the Calvin cycle, sugars or carbohydrates are synthesized.

When carbón dioxide, CO₂, enters the leaves through stomas, it diffuses to the chloroplast stroma. Carbon atoms fixate, meaning that they incorporate into organic molecules. These molecules are used to produce 3-C sugars.

The whole process is impulsed by ATP and NADPH coming from light-dependent reactions.

The alternation of the processes of light-dependent and light-independent reactions help the cell conserve energy and matter.

Plants takes solar energy and produce ATP and NADPH. When there is no available solar energy, the plant uses these molecules to produce carbohydrates.

The correct option is D. to produce glucose

Inputs are in the other answer, and since you asked I'll give the outputs:

glucose (for the plant - created by the Calvin Cycle [through the input of Carbon dioxide]) and oxygen (which the plant does not require, so it exits the plant - created through the water input)

If you want to get really technical, the input light is absorbed and its energy is used to drive electrons from the water. These electrons generate NADPH, which drives protons across the membrane. The protons will then return to make ATP (which is through ATP synthase). (There are some good diagrams of this you could find on the internet for a better visual if needed, but since they aren't mine, I feel I should not post them)

The color of dog breeds can be black (BB or Bb) or brown (bb), and the ability to create pigment depends on the presence of the A gene (AA or Aa). The aa genotype results in no color (albino/white). Punnett squares can be used to predict the possible genotypes and phenotypes resulting from a cross between two dogs.

To determine the possible outcomes of a cross between two dogs, we can use a dihybrid Punnett square. Let's assume one dog is black (BbAa) and the other is brown (bbAA).

The Punnett square for the BbAa x bbAA cross would look like this:

 Bb    Ba

bb | Bbba | Bbaa

bb | bbba | bbba

From the Punnett square, we can see that there are four possible genotypes for the offspring: Bbba, Bbaa, bbba, and bbba. Among these genotypes, the Bbba and Bbaa genotypes will result in black-colored dogs, while the bbba and bbba genotypes will result in brown-colored dogs.

It's important to note that the presence of the A gene is necessary for color to be expressed, so the aa genotype would result in no color (albino/white) regardless of the B gene.

In summary, the use of a dihybrid Punnett square allows us to predict the possible genotypes and phenotypes of offspring resulting from a cross between dogs with different color and pigment gene combinations.
