A moth's color is controlled by two alleles, G and g, at a single locus. G (gray) is dominant to g (white). A large population of moths was studied, and the frequency of the G allele in the population over time was documented, as shown in the figure below. In 1980 a random sample of 2,000 pupae was collected and moths were allowed to emerge. Assuming that the population was in Hardy-Weinberg equilibrium for the G locus, what percentage of the gray moths that emerged in 1980 was heterozygous? (The Answer is 67%, can you please explain why it's 67%? thank you!!)
Answer:
67%
Explanation:
When taking random samples from a population, the observed numbers are not always as the expected ones. The difference is by chance, instead of 50% heter0zyg0us, the sample included 67%.
--------------------------
Available data:
- Moths' color ⇒ diallelic gene
G allele → dominant → Codes for greyg allele → recessive → Codes for white- f(G) 1960 = 0.8
- f(G) 1965 = 0.7
- f(G) 1970 = 0.6
- f(G) 1975 and 1980 = 0.5
- 1980 ⇒ N = 2000 pupae
- Population in H-W equilibrium
Hardy-Weinberr equilibrium,
Assuming a diallelic gene, p and q are the allelic frequencies in a locus and represent the allelic d0minant or recessive forms. The gen0typic frequencies after one generation are p² (H0m0zyg0us d0minant), 2pq (Heter0zyg0us), q² (H0m0zyg0us recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation.When adding the allelic frequencies of a population in H-W equilibrium, the result should be 1, this is p + q = 1.In the same way, when adding the genotypic frequencies, the result should also equal 1, this is p²+ 2pq + q² = 1In this problem we assume that the population is under H-W equilibrium, and we know that p = 0.5.
Considering that p + q = 1, then by clearing the equation, we get the value of q = 0.5
Finally, we know that the genotypic frequency of the heter0zygous genotype is 2pq, so,
F(Gg) = 2pq = 2 x 0.5 x 0.5 = 0.5 = 50%
Now, among the options in the problem, there is not 50% but others. One of them, and the closest to 50%, is 67%.
The chart reflects that through the years, the moth's populations stabilized. Both alleles were favored, and their frequencies got to be equal to each other -0.5-. So there is a high probability of getting heter0zyg0us individuals in the population -50%-, more than any of the h0mzyg0us ones -25%-.
However, in a natural population, the amount of h0m0zyg0us and heter0zygous individuals observed is not always the same as the expected ones. This fact happens especially when there are random samples.
In this experiment, the researcher took 2000 pupae, but they did not know their genotype. They just took them randomly. Even though the population is in H-W equilibrium, when sampling, the researcher took more heter0zyg0us individuals than the expected ones. It does not mean that the population is not under H-W equilibrium. It just means that by chance, more heter0zyg0us were selected.
So what you need to do in these situations, is to analyze your problem and the provided information, and think about the most feasible answer.
In this case, the expected number is 50% heter0zyg0us. The closest option is 67% and the most feasible. So that would be the answer.

Answer: fertilization
Explanation:
Answer:
Answer is D. Fertilization
Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

The evolution of arthropods has led to
Answer:
Arthropods make up almost 80% of all animals; they are jointed legged animals that belong to the Animalia kingdom that include centipedes, millipedes, insects, and spiders. The success of arthropods can mainly be attributed by the following characteristics;
Presence of Exoskeleton.
The presence of exoskeleton that hardens due to the presence of chitin offers a protective cover for arthropods with different environment against advance conditions and also it protects against dehydration.
Varied habitats.
Arthropods can be found in all types of habitats from the soil, water, and land. This feature is the key to their survival since they are widely distributed hence increasing chances of survival.
Bilateral Symmetry.
Arthropods exhibit bilateral symmetry whereby a different portion of their bodies are mirror images, this form is exhibited in higher animals such as humans and dogs, and it facilitates advanced body functioning.
Jointed Legs.
Arthropods exhibit segmented legs that are jointed to allow the development of hard exoskeleton for protection. The jointed legs are specialized for grasping, jumping and running.
Short generation time.
Arthropods exhibit short generation time, which allows for faster adaptation to the environment and survival.
Reproduction strategy.
Arthropods have exhibited a sexual form of reproduction that is more successful in the growth and survival of offspring.
Segmented body.
Arthropods have a segmented body that allows for specialization of body organs and tissues, and this has promoted their success by specializing body organs to different functions.

04.02 Environmental Resources Lab Report
Instructions: For this lab, use the lab report to record your information. You will submit your completed lab report.
Note: If you cannot complete this lab as directed, please contact your instructor for assistance.
Name and Title:
Include your name, instructor's name, and date.
Introduction
To improve your soil, you should first know what you’re starting with. In this lab, you will sample local soil to determine its composition and pH range.
Materials
• Distilled water
• Metric ruler
• Small zipper storage bag
• Soil from the yard, garden, or other local source
• Jar with tightly fitting lid (tall and skinny would be best)
• Small digging tool
• pH strips (available at hardware and pool supply stores) or vinegar and baking soda
Pre-lab Questions
1. Describe soil particles (sand, silt, and clay) in term of size and texture.
2. If soil is too acidic, what substance is usually added? If soil is too alkaline, what substance is usually added?
3. Why are soil composition and pH important to know?
Hypothesis
Predict what type of soil you think is in your local area (mostly sand, silt, clay, or mixed) and if it more acidic, more alkaline, or neutral.
Procedure
Obtaining soil samples for your jar and resealable bag
1. Take your jar, resealable bag, and digging tool into your garden or yard. Use the digging tool to dig a hole 3–6 inches deep. Take your soil sample from the soil at this depth.
2. Place approximately one cup of soil into the resealable bag, squeeze the air out of the bag, and zip it shut (you will use this soil later in the lab).
3. Dig up additional soil and fill the jar to approximately 1/4 full of soil. Take everything back inside to your work area.
Note: To avoid making a mess, it is best to work on a covered surface (for example, a kitchen counter covered with old newspaper or plastic wrap).
4. Fill the remaining space in the jar with water, and screw the cap on tightly (see Figure 1, below).
5. Shake the jar so that the dirt is totally dispersed through the water (see Figure 2, below). Set down the jar and allow the shaken contents to settle completely (see Figure 3, below). Leave it undisturbed overnight while you test the texture and pH of the soil in your resealable bag.
Note: Do not pick up the jar. Doing so will begin to mix the contents again.
Figure 1 Figure 2 Figure 3
Fill jar 3/4 full of water and 1/4 full of soil. With the lid on tightly, shake the jar well until the soil and water have mixed thoroughly. Let the jar sit. Materials will begin to settle out and form layers.
Testing texture and pH of the soil in your resealable bag
1. While you wait for the soil and water sample to settle in the jar, you can test the texture of the sample in the resealable bag. First, remove a small amount and moisten it slightly to test the texture. Record your observations in the Data and Observations section.
a. Rough and gritty soil that barely sticks together is sand.
b. Loams (mixtures of clay, silt, and sand) feel medium-textured.
c. Smooth and sticky fine textures indicate clay.
2. Next, test the pH using one of the following methods:
a. If you have pH strips: To test with pH strips, place the soil sample in a small bowl or container and add a small amount of distilled water. Add just enough water to make the soil slightly liquid, like a milkshake consistency. Dip the pH strip in and compare it to the color identification provided with the test strips. Record your data in the Data and Observations section.
b. If you do not have pH strips: Use vinegar and baking soda instead. To do this, split the sample into two containers. Add a half cup of vinegar to the first sample of soil, mix gently, and watch to see if it bubbles or fizzes. If it does, it is alkaline. In the second container, add a half cup of distilled water to the soil and mix gently. Then add a half cup of baking soda. If there is a reaction of bubbles or fizzing, the soil is acidic. If neither sample has a reaction, the soil is neutral. Record your data in the Data and Observations section.
Testing soil sample in your jar
1. For the sample in the jar, wait until after the contents have settled and you can see several different-colored layers. In addition, you may see some material floating at the top of the water. You may also see that the water is still clouded with some particles.
2. Measure the total thickness of the soil in the jar after it settles. Record this measurement (in centimeters) in the data table.
3. Observe the settled dirt carefully. There should be distinct layers of soil. The bottom will be your sand layer (largest particles fall out first), then clay or silt, depending on the kind of soil you have. Carefully measure the thickness of any layers of soil seen in your jar. Record your measurements in centimeters (cm) in the data table. Also record the color of each layer.
