What causes polarity?

Biology
1 answer:
Aleonysh [2.5K]3 years ago
6 0

Answer: Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms

Explanation :polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms

Cell division involves two processes mitosis and meiosis. Both of these processes are involved to help the cell divide and result to two diploid  daughter cells and for meiosis four haploid daughter cells. 

<span>A normal, typical and functional cell undergoes cell cycle in normal fashion and eventually reaches apoptosis. Yet cancer cells fail to display just some of these characteristics.

</span><span>The cycle cycle; mitosis occurs more in your body since it changes, modifies and requires cell division at maximum rate in many useful situations with the stand to a particular system and organ. Mitosis and meiosis are simply cell division processes that occurs differently, they're characteristically divergent from each other according to their function and structure. Mitosis is the cell division that happens in all cells in the human body except sperm and egg cells. They produce diploid cells.</span>

A selectively permeable membrane separates two solutions. Water is able to pass through this membrane; however, sucrose (a disac
NNADVOKAT [17]

Answer:

a. Nothing happens because the two solutions are isotonic to one another.

Explanation:

Two solutions of the same molarity are separated from each other by a membrane that allows water molecules but not the glucose or sucrose to move across it. Movement of water across the selectively permeable membrane occurs only when two solutions have different concentrations of solutes. In that case, water moves from a hypotonic solution towards a hypertonic solution. Since both sucrose and glucose solutions have the same tonicity, there would not be any change in the solution.

2) Compare and contrast the structure of the nucleotide that makes up DNA and the nucleotide that makes up RNA.
SCORPION-xisa [38]
Answer: DNA contains the nucleotides guanine (G), cytosine (C), adenine (A), and thymine (T). RNA contains the nucleotides guanine (G), cytosine (C), uracil (U), and thymine (T). The difference between the two is that RNA contains uracil (U) rather than adenine (A).

The base pairs in DNA are adenine with thymine and guanine with cytosine. The base pairs in RNA are uracil with thymine and guanine with cytosine.

Why is silicon distributed unevenly? Someone please answer asap I will give you a brainliest
Ket [755]

Answer:

Inequalities in the exposure to environmental burdens and access to environmental benefits are an environmental justice concern for urban and regional environmental planning. Recent studies have assessed the exposure of different populations to a combination of environmental hazards through GIS-based Cumulative Environmental Impact Assessments (CEIA). The contribution of this study is the development of a CEIA, which incorporates the distance-based impact of transportation, the cumulative impact of environmental hazards, and access to environmental benefits for Santa Clara County (SCC), a highly diverse and rapidly developing region also known as ‘Silicon Valley’. Our results show that social vulnerability, cumulative environmental hazards, and environmental benefits exhibit distinct spatial patterns in SCC.
