Watch the following video and write a scientific summary of your observations: https://youtu.be/jTSC4ntCPY4
Here are your goals for this assignment:
Observe and describe cheek cells
Summarize findings based on observations
Write a summary of your findings from this investigation. Be sure to include your personal observations as well as answering the questions below. (Answer all questions in full sentences.) Your summary should be 150 words or more.
What did you see in the microscope? Be specific and describe as a scientist would.
Did you see more than one cell in the microscope? How many?
Was the cell structure clearly visible? Describe it.
Could you make out any cell components? Which ones?
What did you find out from this investigation? Write a paragraph about your findings.
1, the cheek cell looks like a germ/bacteria and contain nucleus and other organelles.
2, In the microscope I see cheek cells just magnified.
3, No just cheek cells
4, no the cell was not that visible until he zoomed in
no
I found out the cheek cells are disgusting and should never lick them with my tongue.
Answer:
1. I don't have a microscope, the cheek cell looks like a germ/bacteria and contains a nucleus and other organelles.
2. In the microscope I saw several cheek cells, some clumped together, some separate.
3. Not really, they didn't have a pronounced shape.
4. No the cell was not that visible until he zoomed in
5. Not possible
The cheek cells grossed me out, the shape, and color. I found it weird to know that those cells are on our bodies. I honestly didn't learn much about them though.
I hope this helps! :)

One student gave an example of an Avestigation and the other gave an example of an experiment. Which student gave an example of a
scientific investigation? (5 points)
A. Student A because it requires a hypothesis
B. Student B because it requires a hypothesis
C. Student A because it can be done in natural settings

1. Consumers and producers both need nutrients to carry our life functions. On the other hand, producers are organisms that make their own food. Consumers are organisms that need to eat other organisms to obtain energy.
2. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers. Mold plays a big part in material biodegradation, enabling decay and rot necessary in all ecosystems.
3. The form of energy entering the food chain is sunlight, which is being taken by plants to produce glucose as their food energy. When it leaves the food chain, the energy is then heat.
4. The percentage of the energy stored by the grass that is passed onto the hawk is 1%
5. B because you can get more production from the cow's milk and meat.
Answer:
1.) Producers are organisms that are usually autotrophs and make their own food in the ecosystem by the process of Photosynthesis, using sunlight, to provide energy to themselves and later to consumers in the environment. Consumers on the other hand are organisms in an ecosystem that don't make their own food and get the energy from consuming producers, primary consumers or secondary consumers. There are 3 different types of consumers, herbivores, carnivores and omnivores.
2.) The roles of decomposers in an ecosystem is very crucial, they feed on dead and decaying bodies. Therefore these decomposers are in-charge or removing dead matter from ecosystem as well as giving energy back to the ecosystem, as where it started from.
3.) Energy enters a food chain in the form of sunlight, and leaves the food chain in the form of heat.
4.) grass = 100%; rabbit = 100% x 0.10 = 10%; hawk = 10% x 0.10 = 1%
5.) Option B, since receiving meat and milk and other dairy products would be more nutritious to the farmer's family than to eat corn most of the time
Hope this helps!
3. Which statement describes starches, fats, proteins, and
nucleic acids?
A) They are used to store genetic information.
B) They are complex molecules made from smaller
molecules.
C) They are used to assemble larger inorganic
materials.
D) They are simple molecules used as energy
sources.
Answer:B
Explanation: Because if u Look at Protein Carbohydrates Nucleic acid and fatty acid actually they are polymers made up of small units called monomers.Option C is incorrect because these are organic molecules containing carbon so we cannot say that it will form an inorganic structures and the other option says about genetic information so genetic information is only determined by Nucleic acids not fatty acid, Protein or Carbohydrates and last option D is incorrect because nuclei acid didn't provide energy.
The statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).
What are Nucleic Acids ?Nucleic acids are naturally occurring chemical compounds that break down to form a mixture of phosphoric acid, sugars, and organic bases (purines and pyrimidines). Nucleic acids are essential data-transmitting molecules of the cell, and, as they also direct the course of protein synthesis, they control the inherited characteristics of living things.
The two essential categories of Nucleic acids are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). DNA is the master prototype for life and contains genetic material in all free-living organisms and various viruses.
RNA is the genetic material of some viruses. It is also found in all living cells which plays an important role in certain processes like making proteins.
Thus, the statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).

Using careful observation, describe at least two differences between these two limbs. Start with the hand bones.
The wo differences between the hand bones of human and cat limbs are- Number of digits: Human hands have five digits (four fingers and a thumb), while cat paws have four digits. This difference in digit number is due to evolutionary adaptations that have occurred in the two species over time.
What are limbs?Limbs are the appendages of the body that are used for movement and manipulation. In humans and most animals, limbs typically consist of bones, muscles, tendons, ligaments, and other connective tissues that work together to produce a wide range of movements and actions.
Shape and size of bones: The bones in human hands are relatively long and slender, with distinct shapes and sizes for each digit. In contrast, the bones in cat paws are shorter and thicker, and the digits are more uniform in shape and size.
This difference in bone structure reflects the different functions of human hands and cat paws, as human hands are adapted for manual dexterity and fine motor control, while cat paws are adapted for hunting and climbing.
It's important to note that there are many other differences between human and cat limbs, including the structure and function of muscles, tendons, and ligaments, as well as the range of motion and flexibility of the joints.

Which population of frogs is likely to have more changes after many generations?
descendant Species 1: The frogs in the brown hills.
Descendant Species 2: The frogs in the green forest.
Both are equally likely to have changes in their structures.
Explain the reasoning for your answer
The population frogs in the brown hill will have more changes because they cannot camouflage to free in the brown hill,they will have to develop some traits or features that will help them adapt and live comfortably in the brown hill.
What is Population?Population refers to a group of living organisms of a particular species that can interbreed, living and interacting together at the same time in the same area.

Explanation:
Why are physical and behavioral adaptations important for a sunflowers survival?
Answer:
The sunflower is intolerant to shade exposure and needs full sun exposure. It has adapted to this necessity by having a heliotropic head which rotates to follow the sun, hence the name sunflower. The heads of the sunflower are heliotropic, meaning movement of the head in response to the direction of the sun.
