Why heart disease is not an infectious disease? I need help please

Biology
1 answer:
Sidana [21]3 years ago
7 0

Answer:

The old idea that coronary heart disease is an infectious disease has gained popularity in recent years, and both viral and bacterial pathogens have been proposed to be associated with the inflammatory changes seen in atherosclerosis. Herpes group viruses, notably cytomegalovirus and herpes simplex type 1, have been associated with atherosclerosis and restenosis. Helicobacter pylori and dental infections have also been linked to atherogenesis, but the evidence seems to favor a respiratory, obligatory intracellular bacterium, Chlamydia pneumoniae. The association was originally found in seroepidemiological studies, but the actual presence of the pathogen in atherosclerotic lesions has been repeatedly demonstrated, and during past year the first successful animal experiments and encouraging preliminary intervention studies were published. The causal relationship has not yet been proven, but ongoing large intervention trials and continuing research on pathogenetic mechanisms may lead to the use of antimicrobial agents in the treatment of coronary heart disease in the future.

What two muscles on your muscle list aid in mastication?
Ludmilka [50]
Unfortunately this question is incomplete as no options are provided. IN actual fact,<span> four muscles are involved in mastication. Three of these are responsible for biting down, namely the masseter, the temporalis and the medial pterygoid, whereas one, the lateral pterygoid, is responsible for opening of the jaw</span><span>. All four muscles help to move the jaw laterally.</span>

7th grade work PLEASE help
dolphi86 [110]

Answer:

1. Greenhouse gas -  Without greenhouse gases, the Earth would be a frozen planet.

2. Increase of oxygen - The increase of oxygen caused a cooling event.

3. Asteroid impacts  - Asteroid impacts caused climate catastrophes

4. Tectonic plates - Tectonic plates can warm or cool the planet

5. Cloud covering- Cloud cover complicates global warming

Explanation:

Explanations;

1. In the greenhouse effect, gases in the Earth’s atmosphere (such as carbon dioxide, methane and nitrous oxide) trap infra-red radiation from the Earth that would otherwise be radiated to space. Thanks to this natural process, the Earth’s surface has an average temperature of 15°C w1. Without these gases, our planet would be an icy -18°C, and life as we know it would not be possible.

2. Some 2.5 billion years ago, there was no oxygen in the Earth’s atmosphere. Although the Sun was less bright back then, our planet was habitable partly because the atmospheric concentration of methane was 1000 times greater than it is now. All this changed, however, with the Great Oxygenation Event, which was triggered by the presence of blue-green algaew5. These microscopic organisms had evolved to carry out photosynthesis, and they produced oxygen as a waste product.

3. Around 66 million years ago, the 10 km diameter Chicxulub asteroid collided with the Earth, resulting in the demise of the dinosaursw7. The impact threw dust into the stratosphere, which is thought to have blocked out 50% of the sunlight reaching the Earth. This would have compromised photosynthesis and led to the collapse of food chains. It would also have resulted in a dramatic fall in global temperatures, plunging the Earth into an ‘impact winter’ that would persist for a decade.

4. The Himalayan mountain range – formed as a result of the collision between the Indian and Eurasian tectonic plates – is a prime example of how plate tectonics can have an impact on climate. Over the past 50 million years, the slow uplift of the Himalayas has exposed new rock to chemical weathering. In this process, carbon dioxide from the atmosphere binds to certain minerals in the rock, reducing the amount of atmospheric carbon dioxide and cooling the planet.

5. Clouds have important consequences for the Earth’s climate. Low, thick clouds cool the Earth’s surface, while high, thin clouds warm the climate. Key to the formation of clouds are aerosols – tiny particles that are suspended in the atmosphere. They act as tiny ‘seeds’ on which water vapour condensesw10. Aerosols are much more than simply what you find in a hairspray can. They can be natural (such as dust or sea salt) or anthropogenic (such as pollutants or smoke). An increase in anthropogenic aerosols could therefore result in more cloud formation, which (depending on the cloud height) could potentially offset the full extent of global warming.

Just ask for more explanation, hope this helps.

Should the FDA should give Aquabounty permission to grow and sell transgenic salmon? Why or why not?
True [87]

Answer:

Yes it should be approved

Explanation:

The FDA should give Aquabounty permission to grow and sell transgenic salmon because studies have shown that transgenic salmons which are genetically modified are harmless. This finding has allayed the fears of the people. Permission to grow and sell this type of salmons will make it easier for transportation to other parts of the country because it doesn’t necessarily have to come from the sea. It also ensures there is increased availability of the products all over the country.
