bacteria in the gi tract also produce ________.

Answers

Answer 1

Several vitamins are processed by gut bacteria using their enzymes. Vitamin K, a key cofactor in the formation of prothrombin and other blood clotting components, is synthesised by the gut microbiota.

It is Vitamin K2, a subunit of Vitamin K, which aids in the treatment of osteoporosis and is produced by bacteria found in the colon. These substances are deconjugated by intestinal bacterial enzymes such ß-glucuronidase, sulfatase, and other glycosidases, releasing the parent substances that are easily absorbed across the gut membrane. A large number of endogenous substances, such as bilirubin, bile acids, cholesterol, estrogens, and vitamin D metabolites, are circulated through the enterohepatic system. Additionally, a lot of medications that are eliminated by the liver enter this system, including digitalis, diethylstilbestrol, morphine, colchicine, rifampin, and chloramphenicol.

6. The absorbed dose of electrons is 50 mrad. What is the equivalent dose in J/kg?
O 5.0 x 10-4 g/kg
500 J/kg
5.0 x 10-3 J/kg
50 J/kg

Answers

Answer:

5.0 x 10-4 g/kg

Explanation:

This is because

I mrad is equivalent to 1/100,000j/kg

Therefore,

To convert 50 mrad to j/kg

= 50/100,000

= 5 × 10^-4j/kg.

Millirad is a decimal unit or rad which is the unit for measuring absorbed ionization radiation.

When the heart is in fibrillation, A) there is no contraction of the myocardium. B) effective pumping of the ventricles ceases because the myocardial cells fail to work as a team, and the brain cannot get adequate oxygen. C) the myocardial cells may become damaged from contracting too fast. D) the myocardial cells deplete their oxygen supply because they are contracting too fast, and the lactic acid produced damages the myocardial cells. E) the myocardial cells are contracting together as they should; fibrillation indicates a normal sinus rhythm of 75 beats per minute.

Answers

Answer:

The correct answer is - B) effective pumping of the ventricles ceases because the myocardial cells fail to work as a team, and the brain cannot get adequate oxygen.

Explanation:

When the heart is in an irregular and rapid heart rate due to chaotic electrical signals in the atrial chambers of the heart which leads to a very fast heart rhythm that shows 100 to 175 heart rate. That leads to failure of the myocardial cells that stop the pumping of the ventricles effectively and therefore blood would not reach the brain and the brain would not get an adequate amount of oxygen. This will result in organisms experiencing faint, blackout or stroke-like complications.

Answer:

It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.

While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.

Cells are the structural and functioning units of all living organism. They formed the foundation all living organism.

Based on location and functions, there  are different types of cells. Because some cells transfer messages from one part of the body to another, they are have a head like structure(the cell body) and a  a long pipe shaped structure (axon) and with branches at the end ( dendrites) .These cells are nerve cells. They are located in the CNS  and PNS.

Other cells on animals have almost the same shape with some variations.

Similarities.

Both contains Nucleus, mitochondria

Both contains fluid inclusion called cytoplasm where all organelles,

Both bounded  layer of cell membranes to restrict movement  the cells organelles and to give shapes.

Differences;

Typical animals cells are of different colors based on location in organs .But

nerve cells  are made of the grey color ( granules) of the cell body and white color of the axon. This is uniform for all nerve cells.

Animal cells performs different functions in animals based on location, but nerve cell is for transmission of impulses and action potential only.

Animal cells undergo regeneration after death or damage. The Regeneration of  nerve cells is slow or not possible in most cases. This is the reasons why most neurological disease are incurable.

Animal cells are made up of three distinct parts: the cell membrane, cytoplasm and the nucleus. Cell body, axon and dendrite are the parts of a nerve cells.

Answers

Question:

Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.

Dichotomous Key of Ranunculaceae

#1.

a. Fruit is a group of alkenes.............................. go to step 2

b. Fruit is a group of follicles..............................go to step 4

#2.

a. Petals are not present.....................................go to step 3

b. Petals are present............................................Ranunculus

#3.

a. The flower has 4 sepals.................................. Clematis

b. The flower has 5 sepals................................... Anemone

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium

The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus

Answer:

The species belongs to Delphinium genera.

Explanation:

A dichotomous key is relatively simple to interpret. All you need to do is to:

- carefully observe your organism,

- know some technical terms or have a biological dictionary, and

- follow the descriptions.

The dichotomous key is going to lead you to the answer.

In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.

Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.

So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.

#1.

a. Fruit is a group of alkenes.............................. go to step 2.

b. Fruit is a group of follicles..............................go to step 4.

We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium  

We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

When a person is suddenly cut by a sharp object, a nervous impulse is sent along a sensory neuron to the spinal cord. The impulse is immediately transmitted through motor neurons to produce a response. Which of the following correctly identifies and describes this response?
A.It is a leamed response that does not occur in infants and small children
B. It is a reflex response that causes various muscles to contract in order to move away from the object.
C.It is a conditioned response that occurs only to prevent injury!
D. It is a voluntary response that is initiated only after the impulse has been caried to the relevant area of the brain.​

Answers

Answer:

B. It is a reflex response that causes various muscles to contract in order to move away from the object.

Explanation:

I just took the Test

It is a reflex response that causes various muscles to contract in order to move away from the object. Therefore, option (B) is correct.

What is reflex response?

A reflex response is an automatic, involuntary response to a stimulus that does not involve the conscious part of the brain. In this case, the reflex response causes various muscles to contract in order to move away from the sharp object, which helps to minimize further injury. Reflexes are a protective mechanism that can operate without the need for conscious control or decision making.

The reflex response described in this scenario is not a learned response, a conditioned response, or a voluntary response. It is an innate, automatic response that occurs in response to a specific stimulus, and it occurs in both infants and adults.
