Don the stockings before getting out of bed in the morning.


To prevent distention of the veins, stockings should be applied before the legs are placed in a dependent position. Stockings should be used preventively before the discomfort associated with venous pressure and edema occurs. Knee-high stockings should end 2 inches (5.1 cm) below the knee to avoid popliteal pressure, which limits venous return. Stockings apply uniform pressure. Elastic bandages may slip or develop wrinkles, creating uneven pressure and constriction; edema may result.

professor190 [17]

Answer:

The situation in which some individuals have greater reproductive success than other individuals in a population. Along with variation and heritability, it is one of the three conditions necessary for evolution by natural selection.

There are so many factors that contributed to this over time, reproductive success differs and it could be attributed to hereditary and variation as well. Most often, the hereditary plays the most role out of all as the viability of both eggs and sperms could have been inherited from parents or being affected as a result of environmental factor or nutrition or other factors.

For instance, if one has a rhesus factor of negative and went ahead to marry another male counterpart with negative rhesus factor, this sedomly leads to miscarriage which could have been controlled had it been they were thoroughly counseled. Furthermore, physical factor such as accident could damage one spermatical vessicles that houses the sperm cells which render such an individual to be unable to donate a viable sperm cell for reproduction.

Those with high rate of reproductive success thrives as result of having many offspring which increases their chances of having more offspring than those with little success rate.

What are some of the functions of photosystem i and photosystem ii in plants?
Sidana [21]

Answer:

Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.

Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.

PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).

PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).

Which statement is TRUE?
Phantasy [73]

Answer:

A

Explanation:

All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.

The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).

The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.
