What is an important component of ATP that is needed to transfer
and release energy directly?
Select one:
O a. Nitrogen
b. Phosphate
O c. Zinc
O d. Uracil
Answer:
b. Phosphate
Explanation:
Adenosine Triphosphate (ATP) is an adenine nucleotide molecule with three phosphate groups. This molecule (ATP) is known as the energy currency of the cell because it releases energy by its hydrolysis to ADP and Phosphate. During ATP hydrolysis, the phosphate bonds are broken down, and this energy is used to power different cellular activities.
A plant stores 3000 Joules of energy into an apple. If a pig eats the apple, then a human eats the pig, how much of the apple’s energy does the human incorporate into their body? A. 3000 Joules B. 30 Joules C. 750 Joules D. 3 Joules
According to the 10% law of the ecosystem, human will have 30 Joules of energy out of 3000 joules from apple. Thus option B is correct.
What is the 10% law of the ecosystem?In the food chain, at each trophic level, 90% of the energy from food is used up in metabolism or released as heat while only 10% is transferred to the next trophic level.
So 10% of 3000 joules of energy from an apple will be transferred to the pig which is 300 joules and the pig will give 10% of 300 joules to the human which is 30 Joules. So option B is correct.

Explanation:
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.

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.

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

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.

Major league baseball has had 11 different single-season home run records since 1876. The records are 5, 9, 14, 27, 29, 54, 59, 60, 61, 70, and 73. Which box-and-whisker plot accurately shows these results?
Answer:
Option C
Explanation:
The question lacks the required option. Find the options in the attachments.
It can be seen that on each box plots, 5 different points are plotted. To determine which box plot correctly fits the dataset, we need to confirm if each points corresponds to what they stands for.
The first point on the box plot will be the lowest value in the dataset after rearrangement. i.e 5
The second point represents the first quartile. To get the first quartile, we need to locate the (N+1)/4 th value in the dataset.
N is the total number in the dataset = 11
First quartile Q1 = 11+1/4 = 12/4 = 3
We are to locate the third value in the data set, and the third value is 14, our first quartile value = 14
The next value is the median Q2 = N+1/2 th value.
Q2 = 11+1/2 = 12/2
Q2 = 6th value
Median = sixth value in the dataset = 54
For the third quartile Q3 = 3(N+1)/4 th value
Q3 = 3(11+1)/4
Q3 = 3(12)/4
Q3 = 36/4 = 9th value
The third quartile = 61
Greatest value in the dataset = 73
Since we know the lowest value, the first quartile, median, third quartile and the greatest number of the dataset, then we need to locate the box plot that correctly plots this points on the box.
The given points [5, 14, 54, 61, 73] must corresponds to the plotted points.
Based to the values gotten, it can be seen that only the third box plot correctly shows this results.
Hence, option C is correct.
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.

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.
