How could you determine the best concentration of solutes to give to a patient in need of IV fluids before you introduce the fluids into the patient's body?

Answers

Answer 1

Answer: You would consider the route of administration, for sure. Is the fluid going to be introduced orally? Through an IV line? Knowing the patient's current fluid and electrolyte levels in their blood would be highly helpful. If you put hypertonic solutions in the the body orally, water will be shifted from the circulatory system into the bowel. This may help someone with fluid overload in their blood to remove some of the water from their blood. It would also help to add water to the stool in the digestive system and act as a laxative. (Osmotic saline laxatives work in this manner. If you put hypertonic solutions in an IV you will pull fluids from the interstitial space between cells as well as from the bowels to the circulatory system. This would help reduce edema. If you put hypotonic solutions in the body orally, water will shift from the digestive system to the circulatory system (and will also dilute electrolytes in the circulatory system). This method may be used to reduce electrolyte concentrations in the blood, and to hydrate the circulatory system in general. If you put hypotonic solutions in an IV you would dilute electrolytes in the circulatory system and would shift fluid to the interstitial space between cells. Isotonic is probably the best way to go if you don't want to shift fluids or change electrolyte concentrations in the circulatory / digestive system. 0.9% saline would be an example of this, and is generally the most widely-used solution for basic rehydrating someone through an IV.

I would look inside the nucleus (B) - that's where DNA is located. It's also called nuclean DNA because of this. The DNA is found in Chromosomes, which are kind of "packages" of DNA.

Which group of plants require water for sexual reproduction to occur?a. dicot angiosperms
b. monocot angiosperms
c. cone bearing gymnosperms Eliminate
d. seedless non-vascular plants

Answers

Answer:

Explanation:

The gametophyte of these lower plants produces haploid spores/gametes. These spores/gametes either produce new gametophytes or swim and fuse with another haploid spore/gamete to produce a zygote. The zygote grows into a sporophyte (the other phase of these plants’ life cycle). This is why these plants thrive in moist conditions. Examples are mosses, liverworts, and ferns.

Each degree on the Kelvin scale equals how many degrees on the Celsius scale?-1
-10
-no relationship (different scale)
-2.12

Answers

the answer is 1 kelvin, but we assume that you are converting Kelvin to degree celsius, following the formula T(c)= T(k)-273.15. Subsequently after the omission of -273.15, the relative equivalent of kelvin per celsius will be 1 unit. For example:
Convert: 300 k to degree celsius 301 k to degree celsius
Solution: T(c)= 300 k - 273.15 T(c) = 301 k -273.15
= 26.85 k = 27.85

27.85 k -26.85 = 1 k

Explanation:

During meiosis, homologous sets of four chromatids are lined up along the cell's equator, attached to spindle fibers. Which of the following processes will happen next?A) Anaphase 1
B) Telophase 2
C) Prophase 1
D) Metaphase 2

Answers

Answer:

A) Anaphase 1

Explanation:

In sexual reproduction, Meiosis is a nuclear division of diploid cells that results into haploid cell. In Meiosis 1, the stages involved in the process include;

Prophase I

Prometaphase I

Metaphase I

Anaphase I

Telophase I

In prophase I, the chromosomes condense and it visibility is vivid inside the nucleus. When nuclear envelope starts to break down, homologous chromosomes move closer together.

The important role in prometaphase I is the formation of the spindle fiber in which the spindle fiber microtubules attach to the kinetochore proteins at the centromeres.

During metaphase I, homologous sets of four chromatids (tetrads) move and orient themselves to the metaphase plate with kinetochores facing opposite poles. Followed by a kind of random orientation of homologous pairs at the equator.

This stage is followed by Anaphase I where microtubules slightly pull the chromosomes that are attached together apart. Though, the sister chromatids remain tightly bound together at the centromere. Also, the chiasmata are broken in anaphase I , as well as the microtubules attached to the fused kinetochores pull the homologous chromosomes apart.

This process of meiosis I ends in telophase I, where the separated chromosomes arrive at opposite poles.

From the concept of meiosis I explanation, we can arrive at a conclusion that Anaphase I follows the process where homologous sets of four chromatids are lined up along the cell's equator, attached to spindle fibers.

A) anaphase. It's when the pairs of chromosomes are pulled apart by spindle fibers.

Protists are a group of organisms that are characterized as eukaryotes (they have cells with nuclei) that are neither plants nor animals nor fungi.

The cladogram for protists is constantly changing and, sometimes, there are opposite hypotheses that both have data to support them. What is the implication of a changing hypothesis? It is acceptable because data are still being collected. It is acceptable because everything in science should always change. It is not acceptable because the correct answer needs to be found.
