Which drugs require caution while being used with an older adult who has developed heart failure due to hypertension?
OleMash [197]

Answer:

Answer ..... Decongestants, Amphetamines and over-the- counter cold medications.

Explanation:

The above mentioned drugs require caution  while administering them to an older adult with heart failure developed due to hypertension , this is because the drugs have the tendency of increasing water retention and increasing cardiac load. And this is very dangerous  for such person.

Note that , Long -acting sedatives and narcotics can be administered safely, because they have no negative effect on cardiac function.

Agronomic Principles
Crop Characteristics

Potatoes produce a fibrous root system. These roots are at best no more than 24in long. Thus potatoes are shallow rooted compared to cereals for example, which can root to at least 47in depth. As a result, potatoes are often unable to exploit nutrients and soil moisture at depth within a soil profile.

While root growth occurs when soil temperatures are between 50 to 95˚F (10 to 35˚C), best, most active root development is at soil temperatures of between 59 and 68˚F (15 and 20˚C).

Leaf (haulm) growth occurs at temperatures of between 44.6 to 86˚F (7 to 30˚C) , but optimal growth is at around 68 to 77˚F (20 to 25˚C). Optimum temperatures for stolon growth are similar.

effects of soil temperature on root development
The potato tuber is an enlarged portion of the stolon. The initiation of this tuber is triggered by short day lengths (photoperiods), and involves growth hormones. The colder the soil temperature, the more rapid the initiation of tubers and the greater the number of tubers formed. The optimum soil temperature for tuber initiation is 59 to 68˚F (15 to 20˚C).

Under these conditions, the potato plant will have short stolons and shoots. Longer day lengths delay tuber initiation and favor the growth of the stolon and shoot. High temperatures also reduce tuber formation. Late varieties seem to be more sensitive to long day lengths or high temperature conditions.

Low nitrogen and high sucrose levels in the plant favor the formation of more tubers.

Once formed, tubers grow rapidly, reaching a maximum rate of up to 1,249 lb/ac/day in temperate climates. See figure below:

Physiological Aging

By planting sprouted seed, crop growth can be advanced. The magnitude of this response and its effect on increasing crop yield is related to the physiological age of the seed at planting.

Suggest two ways you could determine if two species are mimics in nature.
yawa3891 [41]

Answer:

A species could be a mimic if it's colors are slightly off from the creature they're trying to mimick, or, upon closer inspection, have a different body shape than the creature they're trying to mimick.
