Answer:

Why don't we have a complete fossil record of all life that's ever lived? Fossil formation requires a rare mix of physical and biological conditions. Fossils must be exposed at Earth's surface to have a chance of being found. Fossils can be destroyed when rocks erode, melt, or change composition.

Explanation:

For many reasons, the fossil record is not complete. Most organisms decomposed or were eaten by scavengers after death. Many species lacked hard parts, which are much more likely to fossilize. Some rocks and the fossils they contained have eroded and disappeared.

Answer:

Sediment has to cover the bones in order for fossilization to take place

Explanation:

Fossil formation requires a mix of physical and biological conditions. Fossils have to be exposed in oder to find them too, so there might be some that are just too deep in the earth for us to find them

Answer:

: Mitosis and meiosis both are the types of cell division which occurs in the body of living organisms. Mitosis is responsible for growth and development in the body of cat because in mitosis, one cell is divided into two daughter cells and again these two cells divided into four and so on which increases size of organisms, while meiosis is responsible for the production of sex cells in cat which enables them to continue its breeding and produce fertile offspring.

A hybrid crop is different from the original crops as they contain genes from other crops that are beneficial for them.

A hybrid has the genetic makeup of both of its parent crops but may have completely distinct external characteristics. This is due to the fact that two recessive genes from both parent crops can be fused together to create an outward visible impact in the hybrid.

Hybrid plants are the result of the cross-pollination of two plant varieties and the propagation of the seed resulting from the mix. The plant that emerges from this seed combination is known as a hybrid plant.

Explanation:

The Suns own weight keeps itself together and keeps its size and shape. all things have gravity. in this case, the sun keeps it shape with balancing its gravity with the pressure.

The best explanation of why the sun maintains its size and shape is forces exerted by orbiting planets cause the sun to rotate. The correct option is C.

"Orbiting" is one of those digital dating terms that perfectly describes what many of us have experienced but didn't realize had a name. It's when someone you were dating tells you they're no longer interested but keeps in touch with you on social media.

The Sun's own weight holds it together and maintains its size and shape. Everything has gravity. In this example, the sun maintains its shape by balancing gravity and pressure.

Planets orbit the sun in elliptical orbits, with the sun slightly off-center of each ellipse.

Therefore, the correct option is C. Forces exerted by orbiting planets cause the sun to rotate.

Answer:

Water also can move freely across the cell membrane of all cells, either through protein channels or by slipping between the lipid tails of the membrane itself. Osmosis is the diffusion of water through a semipermeable membrane

Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

Hydrosphere:-

The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.

Biosphere:-

The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.

Evaporation:-

The process in which water or liquid converts into vapor is called as evaporation.  In the case of water it starts vaporization at 100 degree C.

So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.

Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

Explanation:

The elephant is getting energy when the bond is broken into sucrose because as sucrose is broken down, it is hydrolized by enzymes sucrase which break the glycosidic bond and convert it to glucose and fructose in the upper gastrointestinal tracts. Glucose and fructose are then absorbed into the blood stream which glucose serve as energy source or stored as glycogen in the gastrointestinal tracts.

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:

DNA replication will occur properly...!

Explanation:

The process ensures that the daughter cells are genetically identical to the cells of the parent.

DNA molecules separate into single strands, which are then used to construct two identical strands of DNA. The two strands wind around each other.

The strand of DNA has a backbone that's made of alternating sugar and phosphate groups. The daughter cells formed are genetically identical to the cells of the parent. They contain identical chromosomes just like their parent cells.
