<em>CORRECT STATEMENTS
> Water forms hydrogen bonds with other polar molecules. </em>
<em>> Water is a polar molecule. </em>
<em>> Water dissolves more ionic compounds.</em>
<em />Water is a polar molecule because of its uneven distribution of electron density. It is made up of two hydrogen atoms and one positive atom.
Since water is a polar molecule, it forms hydrogen bonds with other polar molecules. Though these bonds are relatively weak, however, there are so many of them present in water.
Water also dissolves most ionic compounds due to the fact that water is a universal solvent. When these compounds are added to water, there will be an interaction between the individual ions and the polar regions of the water molecules and disrupts the ionic bonds.
<em>INCORRECT </em>
> Liquid water is less dense than water vapor. - Liquid water has a higher density than water vapor. The fact that water vapor rises indicates that it is less dense than water.
>Water dissolves more hydrophobic substances. - Hydrophobic substances do not dissolve easily in water. It is termed as 'hydrophobic" because it means water-fearing.
Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.
Answer:
there is a good chance the population of mice will die off or the mice will migrate to a new area.
Explanation:
with there being so many mice and limited food mice will beging to die from starvation. mice might also migrated to a new area to find new food. this could cause competition for food in that new area too.
I think the correct answer from the choices listed above is option B. Rescuing someone who is in danger is an example of chivalry. Chivalry is a term used to describe the qualities expected for a knight where one is the readiness to help who needs help.
Three scientists are credited with the development of cell theory. Matthias Schleiden observed that all plants were made of cells; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells.
