Crop rotation is a method of soil conservation because _______. a. the land produces more than one type of crop b. it requires plowing and tilling that reduces soil compaction c. it does not use the same parcel of land in sequential seasons d. it avoids the depletion of soil nutrients
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.

Which action can humans take to reduce wave erosion?
O build drainage systems
O build houses near coastlines
O build breakwaters in the ocean
O reduce vegetation along coastlines
Answer:
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.
What is Wave erosion?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.

Pick one of your concerns. Can you think of two possible ways a conservationist could address this concern to minimize the risk to biodiversity? You may conduct your own research using credible resources to help formulate your answer.
Answer:
I’m going to focus on the risk of fish getting sucked into the dam. My research showed that this is a problem. Fortunately, there are a few ways that this problem can be minimized. One solution is the building of a fish passage, which helps the fish migrate around the dam so they can reach spawning areas. The other solution is to work with the dam’s engineers and owners to construct a dam to minimize the risk to fish. We’d also make a plan for the safe release of the fish.
Explanation:
Answer:
I'm going to concentrate on the possibility of fish being drawn into the dam. I found that this is a problem in my research. Fortunately, there are a few approaches that may be taken to lessen this issue. The construction of a fish tunnel, which aids fish migration around the dam so they can access spawning sites, is one remedy. The other option is to build a dam in collaboration with the owners and engineers of the dam to reduce the risk to fish. We would also devise a strategy for the fish's secure release.

Briefly describe two ways in which the Hardy-Weinberg equation can be used to get information about a population.
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.

Results in the evolution of the species:
Results in new species
Favors traits at the two extremes:
No increase in diversity
One extreme trait is favored
Diversity decreases:
Diversity increases
DONE
Intro
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
Diversity decreases: Stabilizing selection

All materials within ecosystems can be recycled.
Answer:
All the things expect enegry are recycled.
Explanation:
When the decomposer decomposes the organic substances than they are taken by plants in the form of nutrition and minerals. Likewise, the food prepared by the plants are taken by animals and the nutrition is recycled. The oxygen and carbon dioxide cycle is also recycled. When the animals releases carbon then the plants take it and gives out the oxygen. In this way oxygen and carbon dioxide cycle is also maintained in nature.But incase of enegry it cannot be recycled but frequently transfered from one form to another form.

You mix activated yeast with different carbohydrates and measure the CO2 production over a time span of 10 minutes for each type of carbohydrate. Is this experiment a qualitative analysis or a quantitative analysis
Answer:
quantitative analysis
Explanation:
Qualitative analysis refers to quality whereas quatitative analysis refers to the amount or quantity. In this experiment, we see how much carbondioxide gas is produced after the use of different carbohydrates given to the yeast. In this experiment, we want to know the concentration of the product in the reaction not the quality so we can say that this experiment shows quantitative analysis as compared to qualitative analysis.

The lock-and-key analogy is used to describe the Group of answer choices binding of G proteins to transmitter receptors. activation of the nerve impulse. action of transmitter molecules on receptor proteins. degradation of transmitter molecules by enzymes.
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.
