Sudden Cardiac Arrest (SCA)

To comprehend SCA, it serves to see how the heart functions. The heart has an electrical framework that controls the rate and cadence of the pulse. Issues with the heart's electrical framework can result in spasmodic heartbeats called arrhythmias (ah-RITH-me-ahs).

There are numerous sorts of arrhythmias. Amid an arrhythmia, the heart can pulsate excessively quick, excessively abate, or with a sporadic cadence. A few arrhythmias can result in the heart to quit pumping blood to the body—these arrhythmias cause SCA.

SCA is not the same as an issue assault. A heart assault happens if blood stream to a piece of the heart muscle is blocked. Amid a heart assault, the heart normally doesn't all of a sudden quit pulsating. SCA, notwithstanding, may happen after or amid recuperation from a heart assault.

Individuals who have coronary illness are at higher danger for SCA. Notwithstanding, SCA can happen in individuals who seem sound and have no known coronary illness or other danger variables for SCA.

Distribution and habitat

The serval is native to Africa, where it is widely distributed south of the Sahara. It was once also found in Morocco, Tunisia, and Algeria, but may have been extirpated from Algeria and only remains in Tunisia because of a reintroduction programme.

Its main habitat is the savanna, although melanistic individuals are more usually found in mountainous areas at elevations up to 3,000 metres (9,800 ft). The serval needs watercourses within its territory, so it does not live in semi-deserts or dry steppes. Servals also avoid dense equatorial jungles, although they may be found along forest fringes. They are able to climb and swim, but seldom do so.

Spotted Towhee

Northwestern birds migrate eastwards to the central plains of the United States, mostly the northwestern-central Great Plains. In other areas, some birds may move to lower elevations in winter.

Their breeding habitat is chaparral, thickets or shrubby areas across western North America. This bird interbreeds with the Collared Towhee where their ranges overlap in southwestern Mexico.

They nest either on the ground or low in bushes, seldom more than 1.5 m above the ground. The female builds the nest over a period of about 5 days. It is bulky and sturdily made of leaves, strips of bark, twigs, forb stalks, and grasses, lined with pine needles, shredded bark, grasses, and sometimes hairs.

At least two broods, consisting of 3 to 5 eggs, are laid per season. The egg shells are greyish or creamy-white, sometimes with a tinge of green, with reddish brown spots that can form a wreath or cap. The female incubates the eggs alone for 12 to 14 days; the young leave the nest at 10 to 12 days. Nests are parasitized by cowbirds.
These birds forage on the ground or in low vegetation, with a habit of noisily rummaging through dry leaves searching for food. They mainly eat insects, acorns, seeds and berries.

The call may be harsher and more varied than for the Eastern Towhee.
