The graphs here show the distribution of beak depths for the ground
finches on Daphne Major, an island in the Galapagos. The bird beaks were
measured over a multi-year study, including a time period before and after
a drought. The drought reduced the supply of seeds and left most of the
seeds as thick-walled nuts that survived the drought. Analyze the data and
select the claim about natural selection and genetic diversity that is
supported by the data.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select for the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as there were more ground
finches after the drought, and it tends to select for the most fit phenotypes, as there
was an increase in average beak depth after the drought.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select against the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as the average beak size
increased after the drought, but it tends to select against the most fit phenotypes, as
there was a decrease in population size for the finches after the drought
Answers
Answer: (A) Natural selection tend to reduce genetic variation as there was a smaller distribution of beak depths, but it tends to select for the most fit phenotypes, as there was an increase in average beak depth after the drought.
Explanation: The picture below shows proof if needed. On USATP
Natural selection tend to reduce genetic variation as a smaller allocation of beak depths, but it tends to select for the most fit phenotypes, as an increase in average beak depth after the drought.
How does natural selection affect genetic variation?Genetic variations that vary gene and protein role.
If a trait is favourable and helps the someone survive and breed, the genetic variation is more likely to be passed to the next generation.
Thus, option "A" is correct by selecting for or against a specific gene.

Why does the earth have different layers?
Answers
Answer:
The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.

A population of drosophila flies lives in a forest and has variation in their egg-laying behavior. The majority of the flies have the trait of laying eggs in the rotting bark of trees. A small percentage of the flies have the trait of laying eggs in bark that is dampened by sap. The drosophila population moves into a new forested area that is drier, where rotting bark is harder to find than sap. How will the population change over several generations
Answers
Answer:
It will contain a larger proportion of flies that lay eggs in sap because the trait results in a higher chance of reproducing successfully and passing on the gene
Explanation:
Over the years the population of flies that lays egg in the rotten bark will reduce this is because of the low chance of reproducing and there will be an increase in the population of flies that lays egg in the sap because the flies have a higher chance of reproducing successfully leading to an increase in the population and the ability of the gene to be passed on successfully to their offspring in next generation.

With only two lifting platforms and four squat racks, space is limited and training sessions are chaotic. Morning and early afternoon hours are the low-activity times of the day. At 3 p.m., student-athletes fill the room beyond capacity, making individualized instruction and room supervision difficult. What steps should the assistant strength and conditioning coach take to properly address these concerns?

Explanation:
Both students including athletes who undertake the program can be assigned slots relating to some period the classical or athlete should report completing their practice. The slots aren't allowed to continue.
They have a structured exercise template for each person, that helps for easy student or athlete monitoring, based on their skill.
This can be encouraged to students and teachers to attend daily and midday meetings.
Read the passage. Then, use what you know about how populations affect one another during ecological succession to explain what happens on an empty lot.
Imagine what happens in an empty lot that has been cleared of all living things. As in a garden that is no longer planted, only soil remains. Weeds begin to grow in the soil. At first, only plants that need full sun to sprout grow there. But over time, these plants grow taller and shade the ground. Then, a different kind of plant begins to grow there, one that grows only in shady areas. Eventually, the lot is covered in mostly plants that sprout in shade.

In genetics, what does a genotype of Hh signify?
Answers
Answer:
In genetics, Hh means a heterozygote.
Explanation:
Usually, in genetics, H would be the dominant, and h would be the recessive trait. HH is usually dominant, and hh would be recessive. So, Hh would mean a heterozygote. In a heterozygote, this would mean that the recessive trait is in the genotype, but the dominant trait would still take over. This also means that sometimes, the recessive trait can be shown along with the dominant. This can be possible through co-dominance, and incomplete dominance. Hope this helps!
Answer:
CORRECT (SELECTED)
Heterozygous; one dominant allele and one recessive allele

a. rigor mortis.
b. tetanus.
c. fatigue.
Answers
Answer:
a. rigor mortis.
Explanation:
Electricity refers to the power generated from various power sources or power plants such as hydroelectric, wind turbine, solar, nuclear, etc.
Generally, the power supplied to homes, offices and buildings cycles at a frequency of 60 Hertz or 50 Hertz depending on the parameters chosen in countries. If a power line is dropped accidentally into a holding tank for frogs, it would immediately cause their muscles to become stiff due to the current flowing through the power line i.e because the power line is energized and has electrons moving across its terminals. This stiffness is because the high frequency stimuli is causing rigor mortis.

Interdependence Of Organisms
Question Being Answered:
How can the presence of one species benefit another in the same ecosystem?
Hypothesis:
If plants grow in soil that contains worms the plants growth will be greater because worms are able to help decompose organic matter and help distribute it through the soil in a form plants are able to use.
Process Of Lab:
In this lab you will grow two different groups of plants. Group A is considered the experimental group which will grow in soil with worms, Group B is considered the control group which will grow in soil without worms. After the plants grow you have to measure the plant growth for both groups and compare them.
Independent & Dependent
Independent Variable: Presence Of Worms
Dependent Variable: Plant Growth
Safety Procedure
Be sure to follow the safety procedure which means to
Wear safety goggles and lab gown while doing the experiment
Keep lab behavior purposeful
Look over the soil contents and make sure to follow warnings provided on any equipment
Wash hands and lab equipment once done with experiment
Treat living organisms with respect and provide proper care
Report any accidents that happen in the lab to your teacher
Lab Procedure
Step 1: Gather Materials
Two trays that are 10 cm 4’ deep
Potting soil
Lima bean seeds which need to be soaked overnight
Location with sunlight or growth lights
Worms
Graduated cylinder
Water
Black marker
Ruler with metric markings
Step 2: Prepare Two Trays Of Lima Bean Plants
Label the trays Control Group and Experimental Group
Add approximately 6-7 cm of soil to each tray
Plant 6 lima bean seeds in each tray being 2 cm deep and label the plants 1-6
Step 3: Give The Plants Water And Light During Sprouting Time
Keep the environments for both groups identical
Water all the plants following the watering schedule that was recommended on the seed packaging
Use the graduated cylinder to ensure the same amount of water is being given to both groups
Make sure all plants get the same amount of light
Step 4: Measure The Heights Of The Plants At The End Of Week 1
Measure the height of all twelve plants to the nearest cm. If a plant dies mark an x on the data table for that plant and write it in your notes
Use a calculator to find the average heights of the living plants in each groups
Calculate the difference in those average heights by subtracting the average height of the plants in the control group. Use this difference as a basis for comparison
Record measurement observations in your notes and the health of the plants such as leaf colors and size, wilting, unusual growth, brown spots, and any other marks you see
Step 5: Add Six Worms To The Soil Of The Experimental Group Of Plants
Write descriptive notes about the condition of the worms in your notes
Step 6: Measure The Heights Of The Plants At The End Of The Week 3
Repeat step 4
Step 7: Measure The Heights Of The Plants At The End Of Week 5
Repeat step 4
Step 8: Check The Health Of The Worms At The End Of The Study
Are the worms still alive?
Do they all seem healthy?
Have they changed in any way? If so list the ways changed
Are there any new worms
Be sure to write descriptive notes about their conditions in your notes
