Answer:
When two different species having similar ancestors evolve to become different is called divergent evolution.
Birds belonging to different species might all share a common ancestor are also based on divergent evolution. Animals undergo divergent evolution for several reasons such as enviornmental changes and existance or absence of predators.
Some animals or birds adapt according to enviornmental changes for their survival and presence of predators affect the evolution of animals or birds to protect themselves from predators.
For example: Galapogas finches undergo divergent evolution in which they have same ancestors but radiates into different species such as medium ground finches, woodpecker finch, and mangrove finch.

Your task is to decide which dig site is most likely to produce Dimetrodon fossils. What kinds of information do you think would be most useful for making your decision?
To uncover Dimetrodon fossils, researchers must first research the dimetrodon's habitats, then go to modern-day replicas of those past ecosystems.
Dimetrodon fossils: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.

Evaluate f(x) = 2x-17 for x=34
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.

How many valence electrons does carbon have? Is this atom satisfied? Explain.
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).

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.

B. Energy is stored when cells break down sucrose to form glucose and fructose.
C. Energy is stored when a third phosphate group is bonded to an ADP molecule to form
ATP.
D.Energy is stored when minerals are released into the bloodstream.
Answer:
Organisms extract energy stored in glucose molecules. Through the process of cellular respiration, cells make the carbon in glucose into stable carbon dioxide molecules and produce energy. ... Metabolism involves either using energy to build organic molecules or breaking down organic molecules in which energy is stored

How does addition of small amount of water under moist conditions affect the potential for a slump to form
Answer:
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.

What by-product of cellular respiration do our bodies need to get rid of?
Answer:
carbon dioxide
Explanation:
Label the diagram below
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 .

Answer:
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.
What are Consumers?
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.
