Compare a complete digestive system to a gastrovascular cavity. what is the evolutionary value of the system?

Answers

Answer 1
What Is a Gastrovascular Cavity?

The gastrovascular cavity is a structure found in primitive animal phyla. It is responsible for both the digestion of food and the transport of nutrients throughout the body. The cavity has only one opening to the environment. Food goes in and waste comes out that same opening, making it a two-way digestive tract.

By contrast, organisms that have a mouth on one end with an anus on the other end have a one-way digestive tract, called an alimentary canal. Food goes in the mouth, while waste comes out the anus.

Syphilis and chlamydia can be treated with antibiotics.

Both syphilis and chlamydia are bacterial STIs, which means they are caused by bacteria, and bacteria can typically be eradicated with the proper use of antibiotics.

On the other hand, human papilloma virus (HPV), hepatitis C, and genital herpes are viral STIs. Viral STIs cannot be cured with antibiotics; instead, they require antiviral medications which may help manage symptoms or control the virus, but will not completely eliminate it from the body.

How long should you hold your stretches

Answers

I think the best answer would be B)15 seconds 

Answer:

The letter B is the right answer.

Explanation:

Stretching is a practice recommended for everyone, from sedentary to athletes, to improve flexibility. Even sedentary people should stretch, in order to reduce the overload on the joints during simple movements of the daily routine.

Stretching is an exercise aimed at gaining flexibility by stretching muscle fibers. As a result, the muscle moves away from one point to the other, in order to provide more agility and increase the range of muscle movement and elasticity. However, to achieve this goal it is necessary for the athlete to keep stretching for 15 seconds.

Stretching prepares the musculature to exercise any movement, without unnecessary tension. If your flexibility is poor, you should practice every day, including Saturdays, Sundays and holidays.

Yolanda is reviewing a medical record for a patient who is receiving psychotherapy. As a part of her training in medical record confidentiality, she is aware that there are special guidelines regarding psychotherapy notes. Which of the following statements is true of these guidelines?

A. Psychotherapy notes can never be disclosed to the patient.

B. Except when used for data aggregation, psychotherapy notes can't be used without the health care provider's authorization.

C. Except when used by the originator of the psychotherapy notes, they can't be used without the individual's authorization.

D. Psychotherapy notes can never be disclosed, even for health care operations.

Answers

The correct answer is C. Except when used by the originator of the psychotherapy notes, they can't be used without the individual's authorization
Confidentiality is an essential requirement of psychotherapy. in addition, although patients share personal feelings and thoughts, intimate physical contact or relation with a therapist is never appropriate, acceptable, or useful.

The most accurate statement regarding the guidelines for psychotherapy notes under HIPAA is that, with certain exceptions, they cannot be used without the patient's authorization, except when used by the originator of the notes. Thus, the correct statement to the student's question is option (C).

Within the context of medical record confidentiality, special guidelines exist for the handling of psychotherapy notes. According to the Health Insurance Portability and Accountability Act (HIPAA), psychotherapy notes are given more protection than other types of health information. The correct statement concerning these guidelines is:

C. Except when used by the originator of the psychotherapy notes, they can't be used without the individual's authorization.

This implies that the psychotherapy notes are subject to additional protections beyond the typical health information. The notes can generally be disclosed for treatment, payment, and health care operations, but with the consent of the patient, unless an exception such as a court order applies. Furthermore, psychotherapy notes cannot be disclosed without explicit authorization from the patient, except for specific purposes including certain legal actions, oversight of the therapist, and serious threats to health or safety, among others.

Which is not an action you can take to maintain cardiovascular health?

Answers

Answer:

Change your heredity.

Explanation:

We call heredity the phenomenon in which the genes and characteristics of parents are passed on to their offspring. The genetic and phenotypic traits transmitted in this way, in turn, are called hereditary. In terms of health, genetic diseases are passed from parents to children through heredity and unfortunately we cannot change that. That is, we will inherit the diseases of our country, probably.

With this we can state that changing heredity is an action you cannot take to maintain cardiovascular health, however you can exercise healthy practices (such as exercise, balanced diet and water intake) to strengthen your cardiovascular health and decrease the incidence of problems.
