The complete question is as follows:
The diagram shows water molecules as solid ice at 0°C and as a liquid at 25°C. Explain why the arrangement of water molecules is different in ice and water.
Answer:
In low temperatures, hydrogen bonds between water molecules become stable as a result of the movement of these molecules are slow in low temperature which leads to the crystalline form of water due to hydrogen bond. This crystalline form is ice.
on the other hand at a higher temperature water molecules found in liquid form due to the faster and rapid movement of water molecules as hydrogen bonds keep breaking and forming in this setting.
The ozone layer keeps harmful rays from the sun also the atmosphere burns up small deburey from rockets, space trash ex. Also small rocks and particles can get burned before hitting the earth. One of the greatest things is it keeps spefic gasses needed for life like oxygen in the world.
Answer:
The two main processes of cell division, meiosis and mitosis, have in common their main steps. In both cases the metaphase ( pairing of homologous chromosomes), anaphase (migration of chromosomes to the ends) and telophase (beginning of DNA decondensation and cell division) are very similar.
The greatest difference occurs in prophase I of the meiosis, which involves the process of recombination (cross over), resulting in variability in the gametes.
Another difference is that meiosis is a reductional process, where the final result of meiosis will be gamens with half of the genetic information, and in mitosis both cells will be equal.
Answer:
Haploid cells
Explanation:
When a cell undergoes mitosis, it duplicates its genetic material, separates the two sets, and then, via cytokinesis, splits into two genetically identical cells. meoisis is a reduction division that produces haploid cells. Haploid cells re essentially required in gametes. Thus, meoisis produces haploid cells.
Answer: option A - denature
Explanation:
Microbial control agents are KNOWN to DENATURE cell proteins as a step in pathology of many diseases.
And because PROTEINS ACTIVITY depends on their three dimensional configuration, microbe attack and BREAK the bond in order to penetrate the cell membrane.
So, the ONLY right option is A
