What can be said about the polarity of water? A. It prevents hydrogen bonds from forming between water molecules. B. It's the result of a slightly positive charge on the oxygen end of water. C. It causes water molecules to be attracted to other water molecules. D. It's the result of a slightly negative charge on the hydrogen end of water.

Answers

The correct answer is option C. It causes water molecules to be attracted to other water molecules.

The water is a polar molecule. The polarity of the water is due to the electronegativity of the oxygen. Due to high electronegativity of the oxygen the bond of the hydrogen and oxygen is pulled towards itself, which causes the appearance of slight negative charge on the oxygen and slight positive charge on hydrogen.

Due to this slight charge, the water molecules are attracted towards one another and form hydrogen bonds.


the answer is C it causes water molecules to be attracted to other water molecules

Which statement supports the modern extension of the cell theory that states "all living cells come from preexisting cells"? a. All living organisms are multicellular. b. Cells pass on hereditary information. c. Each cell in an organism contains a single nucleus. d. The chemical composition of cells varies by organism.​

Answers

The statement that supports the modern extension of the cell theory that states "all living cells come from preexisting cells" is that they pass on their genetic information. Option B is the correct answer.

What is the presence of nucleus like ?

The presence of nucleus is like the central position in which all the machinery of the cell parts are all included.

All organisms only  inherit genetic information just by  specifying the structure and the  function from parents.  In that case , all  the cells that  arise from the type of the preexisting cells such that  the genetic material needs to be replicated along with passing  from  the parent to the  progeny cell in each  of the cell division.

DNA, or  the deoxyribonucleic acid in which it is hereditary material in  the humans and all  the other organisms.  Nearly every cell in  person's body is having same kind of DNA. A sperm and egg each of them just  contain  a set of  the total pair of 23 chromosomes. When sperm fertilises egg,  then the two copies of chromosomes  are just  present and an embryo just  forms up.

Particles of soil often differ greatly from the underlying bedrock in color, mineral compoition, and organic content. Which conclusion about these soil particles is best made from this evidence?

Answers

Answer:

They are transported sediments.

Explanation:

A solid and very hard stone is called a rock. Geology defines rocks as linked solids that are formed by one or more minerals. The notion of a mother, on the other hand, refers to a female who gave birth or the origin of something. The idea of parent rock therefore evokes what defines and defines the mineral matrix of a soil. In other words, the parent rock is the type of rock on which the soil is supported. Through erosion and a weathering process, the parent rock allows the development of the inorganic sector of the land in question.

However, it is common for the soil to be different from the rock that originated it. This difference can be seen in color, mineral composition and organic content. This is because they are transported sediments.
Let's go through the options: 1 They are residual sediments. No, since the information says they're different in color, mineral composition, and organic content. [ The bedrock would have to be the same if the soil was a residual sediment. 2 They are transported sediment. This seems reasonable. If the sediment is not the same type as the rock, it would have had to come from somewhere else. 3 They are uniformly large-grained. Maybe, but it doesn't say anything about it. 4 They are soluble in water. Again maybe, because it doesn't say anything about it. If you think carefully through each option in questions like these, you can usually think through to what things make the most sense.

The genetic material of hiv consists of _____.

Answers

The genetic material of HIV consists of RNA, which stands for ribonucleic acid.

Unlike most organisms that use DNA as their genetic material, HIV is a retrovirus that carries its genetic information in the form of RNA. The RNA of HIV is single-stranded and contains all the necessary instructions for the virus to replicate and infect host cells.

Once inside a host cell, the viral RNA is converted into DNA by the action of an enzyme called reverse transcriptase.

This viral DNA is then integrated into the host cell's genome, allowing the virus to hijack the host's cellular machinery to produce more viral particles.
