Answer:
The amount of sediment a stream can carry depends on the speed and size of the stream. The speed of the water in a stream depends on its slope. The steeper the slope, the faster the water moves. Fast-moving or large streams can carry more sediment than slow-moving or small streams.

Why is the making of sedimentary rock a physical change? Explain your own answer no goo9le plss
Answer:
The formation of sedimentary rocks is indeed a physical change because we are only changing the physical structure of the rock/rocks by compacting them together, they're still rocks.
Explanation:
Remember that physical changes are when you are only changing a physical characteristic of an object. A common example of a physical change would be breaking a piece of wood. Even though the wood is now smaller, and its physical appearance has changed, the wood is still wood.
Sedimentary rocks are formed by compaction, where many rocks are compacted together, and the pressure causes all the rocks to form together into one big rock.
Sedimentary rocks are formed by many different rocks, which means they are still rocks, but they are now compacted together to form one bigger rock. "The formation of sedimentary rocks is indeed a physical change because we are only changing the physical structure of the rock/rocks by compacting them together, they're still rocks."

9. What would need to change in order for the organism population in the example to continue
growing?
Answer:
If a population is given unlimited amounts of resources, such as food and water, land if needed, moisture, oxygen, and other environmental factors, it will grow exponentially. Exponential growth occurs as a population grows larger, dramatically increasing the growth rate.
Most enzymes in the human body work best at 37C (98.6F). When you get sick, sometimes you get a fever, what do you think this means for your enzymes?
Answer:
Because enzymes are denatured by heat, fevers can cause changes in enzymatic structure and shape. If your fever is high enough to fully denature your enzymes, this can lead to death by preventing your enzymes from catalyzing necessary reactions.

Please HELP ANYONE ASAP what to write out please ?!!!!!):
Answer:
More and more of the medium ground finch population would develop the characteristic of having a thick beak for breaking larger seeds. It would be a small amount of them having the characteristic at first, but then gradually the amount would increase until all of them keep this characteristic.
This is an example of natural selection and adaptation. The two words are related, in a way. Natural selection is when a species change over time with a characteristic that helps them adapt better to their environment. The medium ground finch population has to adapt in the change of environment through natural selection of getting the characteristic of thicker beaks for bigger seeds. Developing this characteristic will help more survive and reproduce, allowing the natural selection process to take place easier and quicker.

Biotechnologies used in crop production have increased our food supplies, but this food abundance has also increased food and energy waste. How can we decrease energy waste within our food supply chain?
Distribute exported foods to other regions.
Use fossil fuels in food production facilities.
Use imported food resources to feed livestock.
Use energy efficient technology in food storage.
F.L.V.S
Using energy-efficient technology to store foods will help decrease energy waste within the food supply chain.
Energy-efficient technologyThese are technologies that are optimized to consume as low energy as possible during the course of usage.
The abundance of food through biotechnologies requires that more foods are stored.
Not using energy-efficient storage technologies will result in high energy consumption. It is either that or food wastage increases.
Thus, using energy-efficient technologies to store food will limit both food and energy wastage.

Flower Dissection — Part 2
Pick a flower from your yard, a public location, or somewhere in your neighborhood.
Start by removing the sepals of the flower with a tweezer. If you do not have a tweezer, a small pair of scissors will also work. It may be easiest to do this if you hold the flower with your finger from below the pedicel (small stalk just underneath the flower) and begin to remove the sepals with a pair of tweezers.
Using tweezers, place the sepals on the labelled printable worksheet, and tape them in place.
Repeat the same procedure for the petals and pistil.
Remove all but one of the stamens and tape them onto the worksheet.
On your printable worksheet, you should have sepals, petals, stamens and one pistil.
Take a picture of your worksheet with the flower pieces placed correctly, and save it on your computer. You will attach and submit this with your assessment questions.

Flowering Reproduction
Describe how flowering plants reproduce.
How do flowers help other organisms in our environment?
Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.
Describe what occurs during the process of seed development.
Based on your knowledge of flowers, why do you think most flowers are bright in color?
Flowering plants under se-xual reproduction and produces seeds which from which new plants are produced.
What are plants?Plants refers to a large group of organisms belonging to the kingdom Plantae which are mostly green and whose mode of nutrition is autotrophic.
Plants store sugars as starch as use sunlight as an energy source.
Plants in different habitats show adaptations to their habitats.
For example desert plants have few stigmata compared to tropical plants on order to conserve water.
The dermal tissue of plants help to protect them from mechanical injury.
Plants can be grouped as either flowering or nonflowering.
Flowering plants undergo se-xual reproduction and produces seeds which from which new plants are produced.
