in which order do plants development​

Answers

Answer:

According to plant physiologist A. Carl Leopold, the properties of organization seen in a plant are emergent properties which are more than the sum of the individual parts. "The assembly of these tissues and functions into an integrated multicellular organism yields not only the characteristics of the separate parts and processes but also quite a new set of characteristics which would not have been predictable[by whom?] on the basis of examination of the separate parts."[7]

Will osmosis occur
If so , which will water move (into or out of the cell )?
Will the cell swell or shrink ?
The cell is In what type of solution ? (Hypertonic , hypotonic ,isotonic ) help pls

Answers

The percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

What is osmosis?

Osmosis is the spontaneous diffusion or flow of water or other liquids over a semipermeable membrane, or one that prevents the passage of solutes, or dissolved compounds. The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer. Inaccurate investigations of leaky membranes, such as animal bladders, and the movement of water and other chemicals through them were previously conducted by other researchers.

A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute. The osmotic pressure, also known as the pressure exerted on the solution, can be raised to a certain level to halt this process. Jacobus Henricus van 't, Hoff, a Dutch-born chemist, demonstrated in 1886 that Henry's rule is obeyed if the solute is sufficiently diluted that its absolute vapor pressure is above the solution.

Therefore, the percentage of water inside the cell is 2.5 %. Water will move into the cell and it will swell. So it's a hypotonic solution.

Answers

Answer:

She suggests doing three main things to prepare: adapting to violent storms and floods, preparing for heat and drought, and adapting to the rising seas by rebuilding and restructuring.

The three examples of Arroyo that gives an idea of the massive impact of climate change are adapting to violent storms and floods, preparing for heat and drought, and adapting to the rising seas by rebuilding and restructuring.

What is theory of Arroyo?

According to this theory of Arroyo, the first step is to grow food crop varieties that are resistant to drought in order to feed the people that live in these arid areas.

Adopting conservation and protection measures for water sources comes ranked second. Others comprise;

Altruistic water use in residences, farms, and businesses

Utilizing alternative energy sources to cut down on greenhouse gas emissions

Therefore, Arroyo's three adaptation strategies—to ferocious storms and floods, scorching heat, and drought—as well as its rebuilding and reorganizing efforts in response to rising sea levels—all serve as illustrations of the significant effects of climate change.

What’s the term to describe a mutant viral protein without a genetic code that can cause disease?

Answers

Answer:

'Prion' is a term first used to describe the mysterious infectious agent responsible for several neurodegenerative diseases found in mammals, including Creutzfeldt-Jakob disease (CJD) in humans.

Explanation:

The term to describe a mutant viral protein without a genetic code that can cause disease is a "prion." Prions are abnormal forms of proteins that can induce misfolding of normal proteins, so option a is correct option.

The misfolded prion protein can convert normal proteins of the same type into the abnormal misfolded form of protein, leading to a chain reaction and accumulation of misfolded proteins. This can cause damage to brain tissue and result in the characteristic symptoms associated with prion diseases, which include changes in behavior, neurological dysfunction, and ultimately, severe neurological degeneration. so option a is correct option.

Answers

The genotype of an individual without a widow's peak would be aa.

A person with widow's peak has. at least a parent with the trait. When both parents have a straight frontal hairline, all the children also have a straight frontal hairline.

The above features are indications that widow's peak is a dominant trait.

Since A and a are used to represent the alleles, AA or Aa will be the genotype of individuals with widow's peak while only aa will be the genotype of individuals with straight frontal hairlines.

In other words, individuals without a widow's peak will have aa as genotypes.

Forman1911THE MATCHThere never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.What does the author mean by we may say that nature strikes a match?A. Matches were created by nature.B. Matches did not help people.C. Matches required natural chemicals.D.
