Answer:

The tissue type in the respiratory system complements its function by providing the structural support and specialized features necessary for efficient gas exchange. The respiratory system is responsible for bringing oxygen into the body and removing carbon dioxide, and different tissue types in the respiratory system are adapted to perform these functions effectively.

The lungs are the primary organ of the respiratory system, and they are made up of several different tissue types. The outermost layer of the lungs is the pleura, which is a thin, transparent membrane that surrounds the lungs and allows them to expand and contract during breathing.

Inside the lungs, the tissue is divided into small air sacs called alveoli. The alveoli are lined with a specialized type of tissue called the alveolar epithelium, which is made up of cells with thin, flattened shapes that allow for efficient gas exchange. The alveoli are also surrounded by a network of capillaries, which are small blood vessels that carry oxygen and carbon dioxide between the lungs and the rest of the body.

In addition to the alveoli and capillaries, the lungs also contain a network of tubes called bronchi and bronchioles, which help to distribute air throughout the lungs. The walls of these tubes are made up of smooth muscle tissue, which allows them to expand and contract to regulate the flow of air.

Overall, the tissue types in the respiratory system are well-suited to their functions, providing the structural support and specialized features necessary for efficient gas exchange. This allows the respiratory system to perform its vital role in bringing oxygen into the body and removing carbon dioxide.

Explanation:

The calculated answer for the torque is  5.357 Nm and the force is 17.28 N for the forearm given in the figure.

We must determine the required torque and the force that the triceps muscle produces in order to answer the issue.

We are aware that the conservation of angular momentum is disrupted when a system receives a net torque, which causes angular acceleration.

Allow the arm to be massless here.

A symbol for the torque is as.

             τ=Iα

Where (I) is the moment of inertia.

α is the angular acceleration.

So,

 τ=mR^2 α

   τ=mRa

Here we have used the relationship between angular and tangential acceleration, which is: α=a/R.

The position vector is:  R = 0.31

The mass is m =2.7

The tangential acceleration is:   a =6.4 m/s2

So, the torque will be,

τ=2.7*0.31*6.4

 =5.3568

So, the required torque is 5.357 Nm.

And we know that torque is:  τ=F.R

So,   force is F =  τ/r

= 5.357/0.31

=17.28 N

The complete question is:

The forearm in the figure(figure 1) accelerates a 2.7 kg ball at 6.4 m/s2 by means of the triceps muscle, as shown. a) Calculate the torque needed. Ignore the mass of the arm. Answer in m*Nb) Calculate the force that must be exerted by the triceps muscle. Answer in N

In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The process begins when the enzyme binds to a region called the promoter region.

The process of transcription refers to the cellular mechanism which used the genetic information provided by DNA to synthesize a complementary RNA strand to a given fragment of the molecule, which is then used to generate a protein in the case of the messenger RNA molecule or mRNA.

Therefore, with this data, we can see that the process of transcription is based on the use of a fragment of a single strand in the DNA nucleotide sequence which is used as a template to create a single-strand RNA sequence similar to the first but complementary.
