Which one of the following is fixed from the atmosphere by bacteria?
O magnesium
O phosphorus
O nitrogen
O sulfur
O potassium
Nitrogen is the following that is fixed from the atmosphere by bacteria. Thus, the correct option for this question is C.
How nitrogen is being fixed by bacteria?Nitrogen is being fixed with the action of nitrogen-fixing bacteria. These bacteria invade the root of the plants where they stimulate the formation of root nodules.
It is the region where bacteria convert the free form of nitrogen into ammonia. This inorganic form of nitrogen is utilized by plants for their proper growth and development.
The fixation of nitrogen in very important. This is because the atmosphere of the earth consists of 78% of free nitrogen which is not usable in form of living organisms. While the fixation of nitrogen converts this free form of nitrogen into usable forms. For example, it can be easily assimilated by plants and other living organisms.
Therefore, nitrogen is the following that is fixed from the atmosphere by bacteria. Thus, the correct option for this question is C.

what are the different ways of storing tools and equipment safe
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.

C. As nutrients increase, the number of life-forms stays the same.
D. As nutrients decrease, the number of life-forms stays the same.
Answer:
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:
As nutrients increase, the number of life-forms increases.Thus, the correct option for this question is A.
What do you mean by Estuary?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.

Is using fossil fuels in generating electricity better or using renewable energy? why?
Answer:
Explanation:
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.

What two groups are represented in archaeopteryx?
Please help
Answer:
The species of Archaeopteryx is lithographica and siemensii
Explanation:
Fun fact: Archaeopteryx is a combination of two ancient Greek words: archaīos, meaning "ancient," and ptéryx, meaning "feather" or "wing."
Archaeopteryx has long been thought to be the earliest known bird and a transitional form between birds and reptiles.
What are Archaeopteryx?Many consider Archaeopteryx, which lived approximately 150 million years ago, to be the first bird.
It is actually a transitional species between the birds we see in our backyards and predatory dinosaurs like Deinonychus.
Many features of Archaeopteryx, such as teeth and a long tail, indicate that it evolved from comparatively tiny carnivorous dinosaurs.
It also has a wishbone, a breastbone, hollow thin-walled bones, air sacs in the backbones, and feathers, as do nonavian coelurosaurian relatives of birds.
Archaeopteryx was thought to be the first recognized bird and a transitional form between birds and reptiles for a long time.
Thus, the two groups that are represented in archaeopteryx are birds and reptiles.

Describe the natural process that creates a human clone.
Answer: Natural cloning also occurs in animal organisms during processes such as budding (offspring grows out of the body of the parent), fragmentation (the body of the parent breaks into distinct pieces, each of which can produce an offspring), and parthenogenesis. In humans and other mammals, the formation of identical twins is a type of natural cloning.

Important Ions move from low to high concentration while using a membrane protein. Which of the following is true? Question 5 options:
A. It's moving down the concentration gradient.
B. Energy is needed to make this happen
C. It's facilitated diffusion.
D. It's osmosis.
Answer:
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.

Which type of rock has a coarse texture due to slow cooling in magma chambers?
A.extrusive
B.intrusive
C.metamorphic
D.sedimentary
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.

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.
What is animal behavior?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.
