Who knows how to do this

Answer:

B. Mixture

Explanation:

Steel is an example of a mixture. It's known as an alloy of iron mixed with carbon. The carbon helps to improve its strength and its resistance to fracture. Other percentages of chromium, nickel, vanadium, etc can be added in order to obtain steels of a desired hardness, resistance to corrosion, etc. Due to its high tensile strength, it is used in tools, ships, cars, electrical appliances, weapons, etc.

Please note: I answered this question with my knowledge of steel and to the best of my ability. The passage that was referred to in the excerpt wasn't added for me to use.

Answer:

1. proteins are assembled on ribosomes

2. proteins targeted for export to the cell membrane, or to specialized locations within the cell. They complete their assembly on ribosomes bound to the rough ER

3. Newly assembled proteins are carried from the rough ER to the golgi apparatus in vesicles

4. the golgi apparatus further modifies proteins before sorting and packaging them in the membrane-bound vesicles

5. vesicles from the golgi apparatus are shipped to their final destination in or out of the cell

Answer:  Sense food, Predators

Explanation: They can observe the animals odor and they can also observe the animals predators.

Scientists are inspired to the survey of animal behavior for a variety of reasons, and the ground is pretty varied, ranging from feeding behavior and habitat selection research to mating behavior and social organizations.

Animal behavior encompasses all of the ways in which animals interact with other organisms and their physical surroundings.

Behavior can also be defined as a change in an organism's activity in response to a stimulus, an external or internal cue, or a combination of cues.

Animal behavior connects the molecular and physiological aspects of biology to the ecological.

Behavior is the link between organisms and their surroundings, as well as between the nervous system and the ecosystem. One of the most important aspects of animal life is behavior.

Animal research helps scientists understand how living creatures, both human and animal, function.

Animal research allows us to get a close-up look at living organisms and how their physical, chemical, and functional life systems function.

Thus, this way, a scientist can learn many varied things regarding organisms by learning animal behavior.

Explanation:

To calculate the population density, you will divide the population by the size of the area. Thus, Population Density = Number of People/Land Area. The unit of land area should be square miles or square kilometers. You can use square feet or meters if you are finding the density of a smallish space.

A) it is moving down the concentration gradient

Explanation:

Brownian motion will cause the molecules (or ions) to spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space (Figure). When molecules move in this way, they are said to move down their concentration gradient.

Answer:

The Endosymbiotic theory is the theory that “Cells evolved from previous ancient cells.”

Answer:

the answer is true.

Weber’s law defined that noticeable difference is a constant proportion. So the given statement is true.

In the case when there should be the size of the noticeable difference i.e. delta I should represent the constant proportion with respect to the original stimulus value.

Hence, we can say that Weber’s law defined that noticeable difference is a constant proportion. So the given statement is true.

O A. As nutrients increase, the number of life-forms increases.

Explanation:

common sense

The statement that best describes the relationship between nutrients and life forms in an estuary is as follows:

Thus, the correct option for this question is A.

An Estuary may be defined as a type of ecotone that signifies the transitional zone of two different ecosystems which include the freshwater river ecosystem and the marine water ocean ecosystem.

In this ecotone, the characteristics of both ecosystems are present. Hence, it has a high biodiversity as compared to both ecosystems individually. This region shows maximum diversity and is thus known as the edge effect.

This illustrates that when nutrients in the ecotone increase, the number of life forms i.e. biodiversity increases.

Therefore, the correct option for this question is A.

Answer: Intrusive

Explanation:

If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving intrusive igneous rock a coarse-grained or phaneritic texture.

Hope this helps!! :D

Answer:

intrusive

Explanation:

Intrusive igneous rocks form at some depth within the crust due to slow cooling of magma, resulting in formation of large crystals. Individual crystals can be seen with the naked eye. These rocks are termed texturally as coarsely crystalline or phaneritic.

Using renewable energy will always be better than fossil fuels.

This is because fossil fuels need a very long time to renew themselves. And we will run out of them long before they can renew themselves. Besides this, there is a more concerning and very alarming issue with using fossil fuels instead of other energy sources. Global warming and environmental destruction is a very big problem for us in the 21st century. The air is more and more polluted. Temperatures are rising and oceans are rising with them. We will lose the ability to grow food and raise animals in the future if we continue like this.

answer is included in the picture below.

Answer:

Step 1

Delegate a portion of your garage, shed or basement closet as a place to store tools. Clean out the junk and clutter and make a space only for tools. Figure out how much space is needed for the amount of tools you have. Sweep away cobwebs, dirt and other foreign matter. Get a shelving unit and store chemicals, liquids and paint substances out of the reach of children and pets.

Step 2

Find the parts. Locate cords, bits, nails and screws and organize them. Allocate plastic bins to store smaller household tools. If you have a large tool collection, organize by type for easy location. Keep the parts for each specific tool close by.

Step 3

Clean out dirt and debris from tools. Oil power tools to lubricate moving parts. Repair loose handles and clean out oil or other fluids used to power the tool. Sharpen blades and replace worn out parts.

Step 4

Set up racks. Mount commercially available racks along the wall of your garage or storage area to hang garden tools, cords and other equipment. Screw racks into the wall with screws recommended by the manufacturer and a power drill. Wind long cords in a loop and hang from rack. Place tools on racks by the handle. Draw the outline of the tool with a permanent marker to identify its place, or use labels to mark the location.

Step 5

Create a library. For tools and appliances that have various functions, designate a library area or bin within the storage space for user manuals and warranty sheets. Store the booklets alphabetically and in a dry area. Type up a sheet listing all of the books to create simple table of contents.

Floods and flash flooding Now is the time to determine your area's flood risk. ... Flash floods have a rapid hydrological response in catchments with short lag times, ... Two different types of flood hazard assessment methods were tested: (i) a ... elongation ratio and roughness index can be used to explain the flash flood types.

Answer:

Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Damaging flooding may happen with only a few inches of water, or it may cover a house to the rooftop. A flash flood is = A flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours. Flash floods are usually characterized by raging torrents after heavy rains that rip through river beds, urban streets, or mountain canyons sweeping everything before them.
