How does the anatomy of the endocrine and integumentary systems correlate with the sense organs? What role does radiology and ut
Marta_Voda [28]
1. Every framework has their doing in arranging our body capacities. Regardless of whether it's the heart drawing blood through our body and lungs boosting oxygen and discharge carbon dioxide. Endocrine gives the correspondence through hormones; secrete their hormones directly into the bloodstream and uses blood vessels as information channels. It stimulates sebaceous glands whereas the sex hormones affect the distribution of subcutaneous fat. In addition, the endocrine system regulates metabolism, growth and development of tissues, and sexual functions. The endocrine and integumentary systems correlate with the sense organs, which react to heat, cold, vibration, texture, and pressure. When such senses are produced by the sense organs they react to the senses and send the information to the endocrine system and therefore hormones are released which causes the mood swings according to the situation. For example, it reacts to the body with pleasure or discomfort related to the senses.

2. Atomic solution and radiology bring the procedures which analyze and regard maladies by utilizing radiopharmaceuticals as the pictures of body organs or envision certain infections. This involves radiations which are used to diagnose, treat and prevent certain diseases. In the present era, these procedures are the best and hence the most effective life-saving techniques. They are safe and painless as compared to other surgical treatments involving operations. They don’t even require anesthesia. Both of these techniques are used in diagnosing a disease and monitoring the course of an illness. They are then used for the treatment of any disease as well. Diseases such as cancer or heart disease are therefore treated by radiation technology.<span>

8. Now figure out how many sheets of graph paper you would have to use to list all the bases in a gene of 90,000 bases (not far
Oksana_A [137]

Now it is clear that genes are what carry our traits through generations and that genes are made of deoxyribonucleic acid (DNA). But genes themselves don't do the actual work. Rather, they serve as instruction books for making functional molecules such as ribonucleic acid (RNA) and proteins, which perform the chemical reactions in our bodies.Proteins do many other things, too. They provide the body's main building materials, forming the cell's architecture and structural components. But one thing proteins can't do is make copies of themselves. When a cell needs more proteins, it uses the manufacturing instructions coded in DNA.The DNA code of a gene—the sequence of its individual DNA building blocks, labeled A (adenine), T (thymine), C (cytosine) and G (guanine) and collectively called nucleotides— spells out the exact order of a protein's building blocks, amino acids.

Occasionally, there is a kind of typographical error in a gene's DNA sequence. This mistake— which can be a change, gap or duplication—is called a mutation.

(a) (1 pt) Assume diastolic blood pressure is normally distributed in a certain population, with a mean of 82 mmHg and a standar
Natali [406]

Answer:

2.275% of this population has a diastolic blood pressure less than 60 mmHg

Explanation:

Hello!

Yo have the distribution of the diastolic blood pressure in a certain population. Be X: diastolic blood pressure of an individual, X~N(μ;δ²)

Where

μ= 82mmHg

δ=11 mmHg

You need to calculate the probability of an individual of this population having less than 60mmHg diastolic blood pressure.

Symbolically:

P(X<60)

To obtain the value of probability you need to standardize the value of diastolic pressure so that you can obtain it from the standard normal distribution. The way to standardize the value is to subtract the mean and divide by the standard deviation

Z= (X-μ)/δ~N(0;1)

P(Z<(60-82)/11)

P(Z<-2)= 0.02275

I hope it helps!
