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.

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.

describe how fertility drugs help women to become pregnant
Answer:
Fertility drugs contain FSH and LH, which stimulate eggs to mature in the ovary. Fertility treatments increase a woman's chance of becoming pregnant, although the treatment may not always work. On the other hand, because the treatment boosts the production of mature eggs, it increases the chance of twins or triplets.
Which is a negative effect of rising ocean temperatures?
the drying out of fertile land and the formation of dust bowls
o the flooding of low-lying coastal areas
O the faster evaporation of water in the soil
O the decreased frequency of major storms
The branch of biology which deals with the study of oceanic water is called oceanology.
The correct answer is B.
The level of the ocean is rising every day due to increases in earth temperature due to excess emissions of carbon dioxide.
The rise of carbon dioxide will lead to increases in temperature that melt the ice. The melting of ice increases the sea level which is dangerous to the coastal or those areas that live near the ocean and might get sunk.

Red-green color blindness is an X-linked recessive disorder that is passed through generations and can be traced by using a pedigree. A pedigree is shown. Sam, Bella, Joshua, and Tim have filled-in shapes. Lisa and Monica have half-filled shapes. Which individuals in the pedigree are identified and labeled carriers for red-green color blindness? Lisa and Monica Sam, Tim, Bella, and Joshua Ben, Jenny, Mike, Carol, Katie, and Chris Ben and Lisa
Answer:
Lisa and Monica
Explanation:
The correct answer would be Lisa and Monica.
For X-linked recessive disorders, a female can be unaffected, a carrier, or affected. However, a male can either be affected or unaffected and never a carrier. This is because females have two X chromosomes while males have only one.
In addition, completely filled-in shapes in a pedigree mean that such individuals are affected for the trait in question while half-filled shapes mean the individuals are carriers for the trait.
Hence, individuals in the pedigree that are labeled carriers for red-green color blindness are Lisa and Monica (they both have half-filled shapes).

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

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:

Apple maggots are a type of fly native to North America. Prior to the introduction of the apple tree to North America, apple maggots fed from and laid their eggs on hawthorn trees. After apple trees were introduced, some apple maggots began feeding from and laying their eggs on apple trees. Adult apple maggots will only mate on the type of tree on which they were born. What is the most likely consequence of the introduction of apple trees to apple maggots
Answer:
B
Explanation:
Populations of apple maggots that mate on different trees could become reproductively isolated and eventually speciate.
Answer:
The correct answer is option B
The population of maggots on the apple tree (apple maggot) that will mate on different trees could become reproductively isolated due to different habitat (ecological isolation).
Ecological isolation causes speciation by creating reproductive barriers between populations due to different habitats.The maggot populations will mate on different trees and will eventually speciate over a period of time.

How could a scientist use the scientific method to learn more about the Cretaceous era?
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:
Identify an unresolved issue or problem that you would like to address. Make a hypothesis that raises answers to these questions or problems. Carry out a series of investigations and experiments dedicated to verifying the hypotheses raised. Finally, having verified the hypotheses, propose a law or rule for the investigated questions.Learn more in https://brainly.com/question/19496416
