Answer:
Since the beginning of life of the first multicellular organisms, the preservation of a physiologic milieu for every cell in the organism has been a critical requirement. A particular range of osmolality of the body fluids is essential for the maintenance of cell volume. In humans the stability of electrolyte concentrations and their resulting osmolality in the body fluids is the consequence of complex interactions between cell membrane functions, hormonal control, thirst, and controlled kidney excretion of fluid and solutes. Knowledge of these mechanisms, of the biochemical principles of osmolality, and of the relevant situations occurring in disease is of importance to every physician. This comprehensive review summarizes the major facts on osmolality, its relation to electrolytes and other solutes, and its relevance in physiology and in disease states with a focus on dialysis-related considerations.
Which of the following is an example of evolution?
A. Plants colonizing inland areas after developing vascular systems that can hold and transport water.
B. An organism developing immunity to a disease after surviving it.
C. A Chameleon changing color when entering a different environment.
D. An organism dying because it is not adapted to its habitat.
Answer: B
Explanation: because it adapt to its environment to survive
The development of an organ system like a vascular system over a long period of time in plants is an example of evolution. Thus option A is correct.
What is evolution?Evolution is a series of events that have taken place in several years to make the species more advanced for the environment due to the introduction of multiple mutations in the genetic sequence.
During evolution, plants have gained the genetic mutation that codes for the vascular system which provide support and transports water in plants. So option A is correct.

All of the following statements about ferns are correct except:_________
A) ferns flourish in many habitats, but the majority are located in the tropics.
B) the sporophyte is a conspicuous generation.
C) sori are located on the back or ventral surface of fronds.
D) the gametophyte is a conspicuous generation.
E) ferns have underground stems called rhizomes.
Answer: B) because in higher plants, such as angiosperms and gymnosperms, the sporophyte is the dominant generation.
All of the following statements about ferns are correct except the gametophyte is a conspicuous generation. Therefore, the correct option is D.
In ferns the gametophyte is usually much smaller and less noticeable, whereas the sporophyte is the more noticeable generation. The sporophyte, the famous giant pearl fern plant, is a major stage in the fern life cycle. Gametes (eggs and sperm) are produced by the gametophyte, which is a small, autonomous stage responsible for sexual reproduction.
Therefore, the correct option is D.

Importance of antimicrobial emulsion
Answer:
Citral is a typical essential oil used in the food, cosmetic, and drug industries and has shown antimicrobial activity against microorganisms. Citral is unstable and hydrophobic under normal storage conditions, so it can easily lose its bactericide activity. Nanoemulsion technology is an excellent way to hydrophilize, microencapsulate, and protect this compound. In our studies, we used a mixed surfactant to form citral-in-water nanoemulsions, and attempted to optimize the formula for preparing nanoemulsions. Citral-in-water nanoemulsions formed at So 0.4 to 0.6 and ultrasonic power of 18 W for 120 seconds resulted in a droplet size of < 100 nm for nanoemulsions. The observed antimicrobial activities were significantly affected by the formulation of the nanoemulsions. The observed relationship between the formulation and activity can lead to the rational design of nanoemulsion-based delivery systems for essential oils, based on the desired function of antimicrobials in the food, cosmetics, and agrochemical industries.

Why did the White House experience water damage ?
1.
It is made of granite which is strong.
2. It is made of sandstone which is very porous and is easily penetrated by rainwater
3. It is made of non-porous sedimentary rock
The White House building is made of sandstone which is very porous as a result water is easily penetrated inside it which causes damage and make the walls of building weak.
The White House is made of gray-colored sandstone that is brought from quarry in Aquia, Virginia. The north and south porticos of white house building are constructed with red Seneca sandstone brought from Maryland. These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.

Given the gene sequence GGACCGTCGATCTTC, which of the following choices would represent an inversion mutation?
A. CCACCGTCGATCTTC
B. GGACTCGATCTTC
C. GGACCGTCGATCTTC
D. GGACCGTCGATCCTT
Reset Selection
ASAP
Answer:
D. GGACCGTCGATCCTT
Explanation:
Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.
Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.

what is adaptation give any four characters of aquatic plants
Explanation:
Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.
1] Aquatic plants have leaves that float on the surface of water.
2] Thier leaves are rarely have stomata.
3] Thier leaves can perform all the work without xylem.
4] They are usually lack cuticle layer in order to avoid excessive dryness.
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.
Four characters of aquatic plants are as given below:
1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.
2) aquatic plants keep their stomata always open for they do not need to retain water.
3) on each side of their leaves are a number of stomata.
4) aquatic plants have less rigid structure since water pressure supports them.

black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.
Answer:
100,000
Explanation:
pH of coffee = 5
pH of solution = 10
Concentration of H+ ions between successive pH values are in multiples of 10
Hence, the pH difference :
pH of solution - pH of coffee
(10 - 5) = 5
Hence, difference in H+ ions will be :
10^5 = 10*10*10*10*10 = 100,000 times
