The right answer is by determining changes in the heartbeat

Three questions are unavoidable when interpreting an ECG:

• What is the heart rate?

A normal frequency is between 50 to 100 / minute. Below 50 / min, we are talking about bradycardia, above 100 / min, we are talking about tachycardia.

• Is the heart rhythm regular or irregular (arrhythmia)?

On a normal ECG, the space between 2 Q-R-S is always the same regardless of the time of recording (in green in the following diagram). This question is fundamental to detect arrhythmias.

• Is the rhythm sinus (or normal)?

Each P-wave must be followed by a Q-R-S segment. This question will help identify conduction disorders between the atria and the ventricles.

bija089 [108]

Answer:

Here are the labels:

6. Zygomatic bone

7. Vomer

8. Mandible

9. Maxilla

18. Sternum

19. Costal cartilage

20. True ribs

21. False ribs

22. Floating ribs

Explanation:

The skull comprises the 8 cranial bones that house and protect the brain and 14 facial bones that protect the sensitive organs such as eyes, nose and mouth.
Out of the 14 facial bones, the mandible, maxilla, zygomatic and vomer along with the frontal bone are the primary bones of the skull.
The rib cage comprises of 12 pairs of ribs connected to the sternum, the main bone that anchors the rib cage, through the costal cartilage.
The ribs numbered 1 to 7 are called true ribs because costal cartilage connects these bones directly to the sternum.
The ribs 8 to 12 are classified as false ribs because they are not directly connected to the sternum.
The last two ribs 11 and 12 are called floating ribs because they do not connect to the sternum at all.

Scientists estimate that there are between 700,000 and 5.1 million fungi on the planet. From your reading of "The fungi: 1, 2, 3

Makovka662 [10]

Answer:

The answer is below

Explanation:

1. This is because there is varying degrees or amounts of habitats and areas that yet to be assessed and examined when carrying out the estimates of fungal species diversity which leads to a broad range of estimates.

2. Also, with the increments in the numbers of different species accumulation that has currently been discovered; a 1.2% increase in species is discovered every year,

Hence, it is ideal to conclude that a large number of species are being discovered in the later research which is making the estimates to be different.

Red-green color blindness is a human x-linked recessive disorder. the normal allele, xb, is dominant to the mutant allele, xb. j

bazaltina [42]

Very interesting problem!

On first reading, it sounded impossible. Tom has normal vision, and there are no male carriers for x-linked recessive disorders. So the daughter can at best (or worst) be carrier of the disorder.

We are told that the daughter has the disorder, but the daughter can only be a carrier with genotype XBXb.

We are also told that Turner Syndrome, which is a disorder related to the x-chromosome. Half of those affected have one of the x-chromosomes missing (monosomy), and some others have some cells with missing or deformed x-chromosomes (mosaicism). Under these circumstances where the normal chromosome is missing, the X-linked recessive Xb allele will be expressed, hence even a carrier can express the red-green colour-blindness.

From the pedigree chart, we can deduce that the colour-blindness must be inherited from Jill, the mother. Tom with normal vision cannot be a carrier because X-linked recessive disorders do not have male carriers.

The daughter's colour-blindness is derived from two sources,
1. inherited Xb allele from mother Jill
2. Turner syndrome that allowed the single allele to express colour-blindness.

Answer 1:
Brushtail possum is an arboreal and nocturnal organism, occupying a wide range of habitat in Australia living in tree, wood land, forest, sleeping day time while active at night.

Answer 2:
This transport was intentional to establish a fur trade. Therefore, this organism was transported from Australia to New Zealand in 1837. Answer 3: This organisn acted as a invasive species. The habitat was suitable for reproduction due to optimum environmental condition. Answer 4: Brushtail possum feed on a variety of resources like they eat leaves, fruits, nuts, insects etc thus disturb the food chain. Even food litters and small creatures whatever they found were eaten. So it pose a serious threat to ecosystem. dairy and derr farmers noticed that introduction of possum cause bovine tuberculosis in live stock. Their numbers were increased and natural predators of possum were unable to control their population size. Answer 5: Possum play dead game. when they see a large animals like human get paralysed for few minutes to an hour.They also have sharp teeth but no evidence was recorded for hurting humans. Answer 6: In order to control population of possum one should aply the procedure of strility or intoduce predators into ecosystem to balance the population of possum.
