The two choices that are true are C and F.

From the given information, we know that Tom and Suzanne are using different formulas to model the number of windows they are installing in their homes. Tom's formula is 42 = 7x + 2 and Suzanne's formula is 37 = 6x + 5, where x represents the number of days they work on installing windows.

To find out which of the choices is true, we can solve both formulas for x. Starting with Tom's formula:
42 = 7x + 2
40 = 7x
x = 40/7
So, Tom is installing approximately 5.71 windows per day.

Now, solving Suzanne's formula:
37 = 6x + 5
32 = 6x
x = 32/6
So, Suzanne is installing approximately 5.33 windows per day.

Based on this, we can see that choice A is false because Tom is actually working at a faster rate than Suzanne. Choice B is also false because we cannot determine who has more windows installed based on the information given.

Choice C is true because Suzanne's formula shows that she already has 5 windows installed before she starts working on any given day.

Choice D is false because Tom's formula shows that he has not yet installed 42 windows.

Choice E is false because Suzanne is not installing 37 windows per day, she is installing approximately 5.33 windows per day.

Finally, choice F is true because Tom's formula shows that he is installing 7 windows per day.

Explanation:

The reason why only about 100 of the millions of known substances are identified as elements is that an element is a substance that cannot be broken down into simpler substances by any chemical means.

It is made up of only one type of atom, which cannot be subdivided further without losing its chemical properties. In contrast, other substances are made up of molecules that contain multiple types of atoms, and these can be broken down into simpler substances using chemical reactions.

The periodic table of elements is a list of all the known elements arranged in order of their atomic number, which is the number of protons in their nucleus. Elements can be identified based on their physical and chemical properties, as well as their position on the periodic table.

Although there are only about 100 elements, they are the building blocks of all matter. By combining different elements in different ways, we can create all the different substances that exist in the world around us. While there are millions of known substances, they are made up of a much smaller number of elements, which underscores the fundamental simplicity of the physical world.

To determine which joints could not be safely reduced in a wilderness setting, it is important to consider the complexity and potential risks associated with joint reduction.

Joint reduction involves manipulating the bones and structures around a joint to realign them properly. Wilderness settings typically lack the necessary resources and medical expertise available in a clinical setting, which can limit the options for safe and effective joint reduction. While I don't have the specific options you are referring to, certain joints are generally considered more complex and riskier to reduce in a wilderness setting. These include:

Complex joints: Joints that have intricate anatomical structures, such as the temporomandibular joint (jaw), sternoclavicular joint (between the sternum and clavicle), and acromioclavicular joint (between the acromion and clavicle), often require specialized knowledge and tools for safe reduction. Wilderness settings are unlikely to have the necessary equipment or expertise.

Weight-bearing joints: Joints that bear a significant amount of weight and forces, such as the hip and knee joints, may require more controlled and precise reduction techniques. In a wilderness setting, it may be difficult to ensure proper alignment and stabilization of these joints during reduction.

Joints with associated neurovascular structures: Joints that have important neurovascular structures in close proximity, such as the elbow joint or knee joint, can be challenging to manage in a wilderness setting. Mishandling or inadequate reduction of these joints could lead to nerve or blood vessel injuries.

In general, any joint reduction procedure in a wilderness setting should be approached with caution, and it is crucial to prioritize the safety and well-being of the injured individual. It is recommended to seek professional medical assistance as soon as possible to ensure appropriate and safe management of joint injuries.

Explanation:

Small interference RNA molecules (siRNA), prevent gene expression by binding to the product of transcription because b.) They bind to mRNA.

Small interference RNA molecules or siRNA sequences are short nucleotide sequences of RNA that are able to bind messenger RNA in order to block gene expression by a mechanism called the RNA interference pathway or RNAi.

These small interference RNAs or siRNA sequences make use of the base complementary to function in order to repress the translation and or induce the process of mRNA degradation through their association with macromolecular complexes such as the RISC complex.

Therefore, with this data, we can see that small interference RNA molecules or siRNA sequences act by binding for complementary to mRNA sequences in order to repress the process of translation and or by degrading the mRNA that binds to the target region.
