Answer:

The answer is the first choice, the person has brown eyes , and the color remains the dominant trait.

Explanation:

When a person inherits a recessive trait and a dominant trait, their (in this case) eye color will always be brown. The only time a recessive trait will be inherited (having blue eyes) occurs when the offspring inherits two recessive traits.

A. The person has brown eyes, and brown eye color remains a dominant trait this typically happens when someone inherits one allele for brown eyes and one for blue eyes.

An allele is one of two or more variations of DNA collection (an unmarried base or a phase of bases) at a given genomic area. A person inherits two alleles, one from every parent, for any given genomic vicinity where such a version exists.

A dominant allele will override the tendencies of a recessive allele in a heterozygous pairing. In a few trends, however, alleles can be codominant—i.e., neither acts as dominant or recessive. An instance is the human ABO blood group machine; humans with type AB blood have one allele for A and one for B.

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 .

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.

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.

Bacteria and fungi are examples of a group of consumers called Decomposers

Explanation:

Bacteria and fungi are the organisms which are examples of a group of consumers called the decomposers. These are herbivores which are dependent upon the dead and decay material for their nutrition.

Consumers are the group of organisms which cannot synthesize their own food and hence depends upon some other organism for their nutritional requirements.

Consumers are classified further on the basis of their nutritional requirements such as herbivores, carnivores, omnivores, etc. Bacteria and fungi are the examples of decomposers which feed upon dead and decay matter for nutrition. These belong to the Kingdom Monera, Protista, and Fungi and the highest tropic level in the food chain of an ecosystem.

Answer:

to study the genetic causes of disease and for the development of diagnostics and drugs.

Explanation:

It is important to extract DNA from a cell in order to study the genetic causes of disease and for the development of diagnostic and drugs. Scientists will use a cell culture system, which is cells from an organism that have either been made to continuously proliferate (grow) or are cancerous in nature (from cancer).

These cells allow us to continue working on experiments where we can change the conditions to determine various cell functions.

Answer:

c = 0.064 j/g.°C

Explanation:

Given data:

Mass of metal = 100 g

Initial temperature of metal = 250°C

Volume of water = 400 mL

Initial temperature of water = 15°C

Final temperature = 15.9°C

Heat capacity of metal = ?

Solution:

First of all we will calculate the heat lost by metal into water.

ΔT= 15.9°C -  15°C

ΔT= 0.9 °C

q = mcΔT

q = 400 g× 4.184 j/g.°C × 0.9 °C

q = 1506.24 j

Specific heat capacity of meta;

ΔT = 15.9°C - 250°C

ΔT = -234.1 °C

q = mcΔT

-1506.24 j = 100 g× c ×  -234.1 °C

(negative sign with q value indicate heat is lost by metal)

-1506.24 j = -23410 g.°C × c

c = -1506.24 j /-23410 g.°C

c = 0.064 j/g.°C
