mariarad [96]

Answer:

<em>Clostridium perfringens</em>

Explanation:

<em>Clostridium perfringens</em> is a bacterium characterized by being a large, gram-positive, boxcar-shaped bacillus.

It is part of the facultative aerobic bacteria group (they can survive both in the presence or absence of oxygen) and is also a spore-forming bacterium (spores are small structures capable of generating new bacteria).

<em>Clostridium perfringens</em> can cause food poisoning, which results from the ingestion of contaminated food (usually meat and animal products) by the bacteria.

Once in the small intestine, the bacteria releases the toxin that usually causes diarrhea.

List the order the steps of the path of blood through the kidneys.
Alexxandr [17]

Blood flows to the kidneys through the right and left renal arteries. Inside each kidney these branch into smaller arterioles.

The blood is at very high pressure and flows through the arterioles into tiny knot of vessels called the Glomerulus. These are located in the nephrons.

From the glomerulus the blood pressure drops and the blood flows into arterioles which coil around the nephrons. These in turn connect to a series of small veins. These vessels reunite and ultimately form the renal vein.

About one quarter of the total cardiac output (or total blood flow) circulates through the kidneys. This equates to just over 1 litre of blood every minute.

Hope this helps (:

Which of the following discoveries is most crucial to explaining why all organisms share the same genetic code?
andreyandreev [35.5K]

Answer:

The correct option is <u>RNA's ability to self-catalyze</u>

Explanation:

A molecule of RNA has the capability to self replicate itself. This ability of an RNA molecule to synthesize more RNA molecules of its own kind is crucial in understanding why all organisms have the same genetic code.

Experiments were performed in labs where RNA molecules were synthesized in an in-vitro lab and their abilities to self- replicate and produce mole molecules of their kind were tested and verified.

Reducing the amount of trans fats in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a
Alchen [17]

Trans fats are the fats that went through hydrogenation, this means, liquid oils became solids, and this is used by the industry to make some food.

The purpose of this is to get a more balanced and better texture in the final result.

They increase the bad cholesterol, and this made us more propense to have coronary heart disease.

This kind of fat is more likely to be found in fast food (fried), all pastry that uses butter and some frozen food like pizza or ice cream.
