Answer: I think it is 51

Explanation:

Answer:

f(34) = 52

Explanation:

f(x) = 2x-17; x=34

1. Plug the number 34 in all the x's you can find in the equation.

f(34) = 2(34)-17

2. Solve the parentheses.

f(34) = 68-17

3. Subtract.

f(34) = 52

4. Answer: If x=34, your answer is 52.

Answer:

4 valence electrons

Explanation:

Because of the relative stability, these atoms often form covalent bonds rather than ionic bonds that need a charge. One example is Carbon. It has 4 valence electrons, so it can make a 4+ or a 4- charge.

Answer:

Carbon has 4 valence electrons. It is not satisfied. To be satisfied, it needs to covalently bond with 4 electrons to achieve octet (8 valence electrons).

Answer:

The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, while mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite.

Explanation:

Answer:

It depends on the shade of the color

Explanation:

Darker colors would obviously attract more heat because of the representation of vibrance and how the sun reacts to the color of something.

It impacts our landscape because darker green trees would most likely cause more wildfires!

Answer:

D)They ensure valid results.

Explanation:

Answer:

1. cuticle

2. leaf epidermis

3. leaf xylem

4. guard cell

5. leaf epidermis

6. stoma

7. root hair

8. ground tissue (xylem vessel)

Explanation:

functions of :

stomata aid in losing of water during transpiration

guard cells regulate the opening and closing of the stomata .this happens when the guard cells have a hypertonic environment they absorb water from the neighboring cells hence they expand and the stomata open .during the night the sugar levels in the guard cells have dropped hence they lose water to the neighbouring cells hence they shrink become flaccid and the stomata close.

xylem transports water to various parts of the plant

cuticle is a thin waxy and transparent layer.it is shiny to reduce excessive loss of water and it is transparent to allow light to penetrate through

root hairs are thin ,long and flexible.they are thin to reduce distance covered by diffusing water,they are long to allow their ability to tap water from underground,they are flexible to increase their ability to reach water sources .

Explanation:

Adding water increases slope instability. It lubricates rock fragments so that they slide down slope more easily. Mass wasting occurs more readily in rainy seasons for this reason. It turns out that a small amount of water in the soil can aid slope stability because of increased surface tension.

Answer: mitochondria

Explanation:

To uncover Dimetrodon fossils, researchers must first research the dimetrodon's habitats, then go to modern-day replicas of those past ecosystems.

Because its remains have been discovered in Texas and Oklahoma in the United States, Nova Scotia, Canada, and all throughout Europe, the Dimetrodon is likely to have been well suited to a broad range of environments.

The first fossil was discovered in the nineteenth century, and Edward Drinker Cope named it in 1878.

Answer:

Epidermis - barrier or protective layer

dermis- thermoregulator or maintain the temperature.

Explanation:

The two main skin layers that are present on the surface of the skin are the epidermis and the dermis layer (below the epidermis). These two layers are helpful in protecting from the excursion.

The epidermis layer is a protecting layer in general that acts as a barrier to protect the inner body from infection and also acts as the waterproofing layer.

The dermis regulates body temperature in an individual if the outer environment is too hot or cold, by sweat in a hot environment as it regulates the sweat glands.

Objective(s)

In your own words, what was the purpose of this lab?

I believe the purpose of this lab is to see how much our society is evolving.

Hypothesis

In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the investigations. You will investigate two different versions of the tree environment as it changes over time: light-colored bark and dark-colored bark. Be sure to list your hypothesis for each environment below.

Example: If I investigate the light-colored bark environment, then I will observe an increase in the light-colored peppered moths over time.

Hypothesis for the light-colored bark: There will be an increase in light-colored of light-colored moths and an decrease in dark-colored moths.

Hypothesis for the dark-colored bark: There will be an decrease in light-colored moths and an increase in dark-colored moths.

Procedure

The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.

Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation.

Test variable (independent variable): The test variable is the colored bark

Outcome variable (dependent variable): The outcome variable is the colored moths population

Data

You will investigate both environments. Record your data for each trial of that environment in the data charts below.

Conclusion

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

What caused the tree bark to become darker?

What caused the tree bark to become darker is the time of the day the darker it is the darker the bark is.

In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?

The light-colored moth had a higher rate of survival than the dark-colored moth.

In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?

The dark-colored peppered moth had a higher rate of survival than the light-colored moths.

During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.

What caused the population of light-colored moths to decrease and the population of dark-colored moths to increase over time was because the dark-colored moths could camouflage themselves on the dark bark trees and the light-colored moths couldn’t protect themselves from predators because they had no where to hid.

Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.

I believe that the dark-colored peppered moth would have a better chance of survival than the light-colored moths because there is mainly dark bark near my neighborhood instead of light-colored peppered moths.

Answer:

Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction. The endocrine system regulates how much of each hormone is released.

The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands.
