Which of the following is an EXOGENOUS source of injury to a cell?
A fever
B bacterial toxins.
C ultraviolet radiation.
D genetic malformation

Answers

Answer 1

Answer:

C. ultraviolet radiation.

Explanation:

Cell injury occurs when cells undergo specific changes when subjected to an internal factor or an external factor. Such change causes "illness" to the person.

Under "toxic injury," two sources may cause an injury to the cell. These are endogenous and exogenous factors. Endogenous factors originate within the body while the exogenous factors originate from the environment.

Among the choices above, it is only the ultraviolet radiation that is considered an exogenous factor because it originates from outside the person's body. Prolonged exposure to UV light damages the cells which can lead to cancer.

You can increase the challenge of your workouts by using Newton's first law of motion. We are given the example of running on sand or biking on gravel. What are some other ways that you can use Newton's first law to create a more challenging workout? When you change the terrain, what is that force called?

Answers

Answer:

Exercise on surfaces that cause your forward motion to slow down so that you have to use more energy to keep moving forward. For example, run on sand instead of pavement or perform aerobic exercise on rubber mats instead of wood flooring. Bicycle through gravel instead of on the sidewalk. This is called biomechanics.

Explanation:

Use Newton's first rule of motion to make your workout more difficult.

This rule says that until acted upon by an external force, a body continues in motion.

By altering the ground on which you exercise, you may reduce the influence of inertia on your exercises, as inertia maintains you going forward. Workout on materials that slow it down your upward motion, requiring you to expend more energy to keep going ahead. Run on sand rather than tarmac, or do aerobic exercises on rubber mats rather than wood flooring.

Explain how intensity could affect performance?

Answers

Generally, it is believed that competitors need an “optimal level of intensity.” This means that when intensity is too high or too low, performance can be affected. A high intensity level can decrease concentration, focus, and create problems with coordination, reaction time, strength, and endurance.
some physical sensations can impact performance if the situation requires a great deal of concentration or accuracy such as golf or a performance sport. The increased adrenalin, heart rate, and muscle tension may actually interfere with performance. In addition, when intensity becomes too high a person might feel increased fatigue instead of energy which can cause slower reactions and reduced coordination. Increased intensity can also contribute to increased negativity, fear, anxiety, and feelings of hopelessness which interfere with performance of physical skills.

Which two things happen during gas exchange in an animal? A. Oxygen moves from blood vessels into the lungs. B. Carbon moves from the blood into the lungs. C. Blood moves from blood vessels into the lungs. D. Oxygen moves from the lungs into the blood.

Answers

Answer:

Options B and D

Explanation:

In animals, gaseous exchange takes place in the alveoli in the lungs. Generally, animals breath-out (exhale) carbon dioxide and breath-in (inhale) oxygen. Thus, carbon moves from the blood in the form of carbon dioxide into the alveoli in the lungs while the oxygen inhaled moves from the alveoli in the lungs to the blood where it is transported round the body as oxyhaemoglobin.

Answer:

B. Carbon moves from the blood into the lungs.

D. Oxygen moves from the lungs into the blood.

Explanation:

During respiration, humans take in air which contains oxygen and the oxygen gas then moves from the lungs into the blood . The blood helps to distribute the oxygen to other parts of the body for their proper functioning.

When we breathe out, we give out carbon dioxide as a result of the carbon which is taken up from the blood into the lungs and subsequently given out to be used by plants for their photosynthetic processes.

Answers

Answer:

B. Working individuals not covered by an employer's health plan must purchase insurance coverage.

Explanation:

The individual mandate under the Affordable Care Act requires legal citizens of the United States to have insurance coverage either through an employer or through their personal means. Failure to meet any of these conditions would result in the payment of fines or penalties when the personal income tax is calculated.

This Act was instituted by Barack Obama's administration in 2010. It is recognized by law and is taken to be a form of taxation.

Coughing is one of the first symptoms, and the most common short-term risk of the damage that tobacco produces in the respiratory system in general.

What is tobacco?

It is a stimulant drug that can increase blood pressure and cause tachycardia, which can lead to addiction.

Tobacco contains several substances that hinder the movement of the cilia which move mucus and debris from the lungs, the smoker coughs because the lungs are trying to eliminate irritants and accumulated mucus.

Therefore, we can conclude that coughing is a short-term risk associated with tobacco use, which appears as a defense mechanism to try to eliminate accumulated secretions.

Juan is depressed because his father has passed away. This is an understandable reaction as he is grieving. This isn't something that is a daily or normal circumstance in his life though and he does have the opportunity and ability to recover and heal emotionally especially with the right support.

Cathy is addicted to cigarettes which already puts her at high risk of developing health problems. All her friends smoke which adds on additional peer pressure and negative environment making it difficult for her to quit. Smoking is also an expensive habit.

Meryl has diabetes which she seems to have inherited. She is at a high risk of developing complications resulting from her diabetes and medical treatment for her diabetes alone is expensive.

Paul is being exposed on a daily basis to polluted air. The only thing he could do about that would be to move but that is expensive. He can't do anything about the coal plant or the pollution and he is at high risk of developing respiratory problems.

Identifying the Causes of
According to the text, what are the likely causes of
precocious puberty? Check all that apply.
In the United States, the onset of puberty has been
occurring earlier and earlier. Today, about 10 percent of
children ages 6 or 7 begin developing signs of puberty, a
condition known as precocious puberty.
In the early 1900s, girls typically began menstruating at
age 17. Today, girls typically begin around age 12. This
trend has been attributed to the growing number of
overweight children and a greater exposure to pollutants.
Exposure to phthalates, artificial chemicals found in
plastics, has also been cited as a cause. These chemicals
disrupt the endocrine system by mimicking hormones in
the body.
Early puberty can have many negative side effects,
including an increased risk of certain types of cancer,
such as breast cancer. Children are often emotionally
unprepared for the physical changes taking place in their
bodies. As a result, behavioral and psychological
nroblems mav increase
exposure to pollutants
exposure to phthalates
certain types of cancers
unhealthy weight gain
disruptions to the endocrine system
emotional and psychological problems

Answers

Answer:

According to the text, the most likely causes of precocious puberty are exposure to pollutants , exposure to phthalates  and unhealthy weight gain.

Explanation:

The age of onset of puberty has experienced significant variations over the years, mostly related to environmental changes and use of processed products.

Factors associated with precocious puberty are:

Industrialization produced an increase in environmental pollutants, which has been linked to early puberty. Consumption of processed foods —which favour obesity— influences the production of hormones, that can induce early sexual maturation.Finally, some chemical additives, such as phthalates, enter the body and resemble the structure of some hormones, inducing a hormonal behavior that promotes alterations, such as an early onset of puberty.

The text also mentions negative consequences for the body when an early onset of puberty occurs.

Rergarding other options:

Disruptions to the endocrine system is the possible explanation for precocious puberty.Certain types of cancers   and emotional and psychological problems are consequences of precocious puberty.
