What is digestive processes

2 answers:

The mouth is the beginning of the digestive tract. In fact,digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.

The mouth is the beginning of the digestive tract, chewing breaks down the food into pieces so it is easier to digest. The throat is the next destination for food, from here food travels to the esophagus. The esophagus is a muscular tube extending from the pharynx to the stomach. The stomach is a sac like organ with strong muscular walls. The stomach secretes acid and powerful enzymes that continues the process of breaking down food. When it leaves the stomach it is a liquid or paste. From there it moves to the small intestine. The small intestine is made up of three segments. The duodenum, jejunum, and ileum, the small intestine is a long tube loosely coiled in the abdomen.

New biosensors, applied like a temporary tattoo to the skin, can alert serious athletes that they are about to "hit the wall" an

Sergio [31]

Answer:

Here are the following options to complete the question

Which of the statements below is the best explanation of why athletes would need to monitor lactate levels?

A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.

B. During aerobic respiration, muscles cells produce too much lactate which causes a rise in the pH of the muscle cells, thus athletes must consume increased amounts of sports drinks, high in electrolytes, to buffer the pH.

C. During anaerobic respiration, muscle cells receive too little oxygen and begin to convert lactate to pyruvate (pyruvic acid), thus athletes experience cramping and fatigue

D. During aerobic respiration, muscle cells cannot produce enough lactate to fuel muscle cell contractions and muscles begin to cramp, thus athletic performance suffers.

A is THE CORRECT ANSWER

Explanation:

When the muscle cells undergoes anaerobic respiration, lactate are produced. Too much accumulation of lactate results in muscle fatigue. It is necessary for the athlete to prevent high accumulation by adjusting their exercise level

Volgvan

Answer:

Option D

Explanation:

Bits of DNA that are interspersed among these repeated sequences are called spacers. Regarding to bacteria, the spacers are taken from viruses that previously attacked the organism. They serve as a bank of memories, which enables bacteria to recognize the viruses and fight against future attacks.

C. At what height would the pomegranate have the same potential energy as the melon? (1 point)

zvonat [6]

Answer:

Given a set of assumptions which are given below, the height at which the pomegranate will have the same potential energy as the melon is 39.19 meters.

Explanation:

Gravitational Potential Energy refers to the acquired innate energy of an object due to its elevation above the surface of the earth.

This energy is the result of gravitational pull or force acting on the object.

In other to determine at what height a pomegranate and a watermelon will have the same potential energy we need to know the other factors in play.

Gravitational Potential Energy (Ep)= mgh

Where m = Mass (kg)

g = gravitational field strength (N/kg)

h = height (m)

Ep = gravitational potential energy ( j )

Let us assume that the

An average pomegranate weighs about 0.255146Kg

An average melon weighs about 10Kg
g is always constant at 9.8 N/kg

Note that melons weight much more than pomegranates.

So, let's calculate for the Ep of the melon at the height of 1 meter

Ep = 10 x 9.8 X 1 = 98j

Using the above assumptions, we do a goal seek using Microsoft Excel. Please see the attached image.

Calculation shows that the Height (h/Meters) at which the Ep of both veggies become equal is 39.19m

This can be verified by inserting the figure and multiplying it. It can also be calculated as follows:

That is

Ep = 98j

m = 0.255146kg

g= 9.8kg

h= ?

98= 0.255146 x 9.8 x h

98 = 2.5004308h (we divide both sides by 2.5004308 to make h the subject matter)

h = 98 / 2.5004308

h = 39.1932462198

Which is approximately 39.19

What are some potential consequences of the widespread use of plastic materials

Oxana [17]

Answer:

Consequences of the widespread use of plastic materials can be an increase in levels pollution and the overflowing of landfills because most plastics are non-biodegradable and can take a very long time to disappear unlike things like paper which are biodegradable.

Match the name of the greenhouse gas with one of the human activities that produces it.

Svet_ta [14]

Answer:

carbon dioxide- burning of fossil fuels

fluorinated gases- industrial processes

methane- production and transport of oil and natural

gas

nitrous oxide- agricultural and industrial activities

Explanation:

Greenhouse gases are gaseous components that induces greenhouse effect. This means that due to their structural ability to trap heat energy in the atmosphere, they contribute to the global warming effect on the Earth. However, this greenhouse gases are produced in large amounts as a result of the day-to-day anthropogenic activities. The following are the greenhouse gases and how they are produced.

Carbondioxide (CO2)- Carbondioxide is the most common and important greenhouse gas. It is generated via natural processes like respiration but also produced when fossil fuels e.g coal, petroleum etc. are burned.

Fluorinated gases- This is another greenhouse gas caused by activities of man. Fluorinated gases are produced in industries during the production of certain products.

Methane- Methane is a gaseous hydrocarbon and the principal constituent of natural gas. Therefore, the production and transportation of oil and natural gases can lead to the escape of methane into the atmosphere.

Nitrous oxide- Nitrous oxide is an oxide of nitrogen. It is mainly produced via agricultural processes such as nitrification and denitrification or use of fertilizers etc. and also industrial actions.
