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.

Which accurately describes the relationship between nutrients and life-forms in an estuary?
O A. As nutrients increase, the number of life-forms increases.
0
B. As nutrients decrease, the number of life-forms increases.
O
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.

Humans have found that we can eat the space cow, and it's delicious! There are no laws currently in place protecting the environment of Planet Z. What would happen to the populations of both the Space Cows and the Vaderians if humans began to hunt for Space Cows on Planet Z?
Will it increase or decrease and why?
if humans begin hunt the space cows they will eventually become extinct causing the vaderians to lose a main source of food which would most likely cause their population to also decrease.

Question: Describe the difference between positive feedback and negative feedback in your own words.
No ones helping me. Only answer if you know :( Due by the end of today
Answer:
Explanation:
The black trait is a recessive trait because it only shows up in 3 people in that is rare. It also only occurs in either male or female looking at the shapes. The first part may be wrong but I believe that this is a Autosomal trait because it isn't occuring in every single person meaning it is a mutation.

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.

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.

In the 1960s the molecular biologist George Streisinger developed the strand- slippage hypothesis. Streisinger noticed that mutations occurred in areas of DNA that contained many repeated sequences. When a strand -slippage occurs, an insertion mutation can result. How does the insertion mutation affect the DNA?
The insertion mutation affects the DNA cause Nitrogenous bases are added to the mix. This is further explained below.
What is a DNA?Generally, DNA is ssimly defined as a molecule found inside cells of a living organism that holds the genetic information.
In conclusion. Nitrogenous bases are added to the mix with the insertion of mutation.

What is the difference between transpiration and diffusion
Answer:
In sunlight the concentration of water and oxygen molecules just inside the stomata is higher than the concentration of the air around the leaves so water vapor and oxygen diffuse, or move out, from the leaves through the stomata. Diffusion, then, is a physical driver of transpiration. Hope this helps!
