The tendency of water molecules to attract one another due to polarity is called _____. ionic bonding hydrogen bonding covalent
Ber [7]

Answer:

The correct answer is hydrogen bonding.

Hydrogen bond is defined as a weak bond that results from electrostatic attraction taken place between hydrogen of one molecule and electro-negative atom of same or different molecule.

In water, partial negative charge is present on oxygen atom which attracts the partial positive charge present on hydrogen atom of other water molecule. This attractive interactions lead to the formation of inter-molecular hydrogen bonding.

Answer:

<em>Moving</em><em> </em><em>of</em><em> </em><em>fan</em><em> </em><em>is</em><em> </em><em>convection</em><em>.</em>

<em>The faster moving air from the fan displaces the warmer air that is in direct contact with our skin. This enhances the rate of convective heat transfer, which means we feel cooler.</em>

The diploid number of chromosomes in the mustard plant, Arabidopsis thaliana, is 10. Knowing this, answer the following question
lukranit [14]

Answer:

10 chromosomes/sister chromatids

Explanation:

Prophase is the first stage of cell division (mitosis). Prior to the cell entering the actual division stage, it undergoes a phase where it prepares its content and most importantly undergo the duplication of its genetic material (DNA). This DNA are found as chromosomes. It undergoes replication of its DNA in the S-phase of interphase stage.

Since Arabidopsis thaliana has 10 chromosomes, and each chromosome holds one DNA molecule, 10 molecules of DNA will be present in the mustard plant's genome. These 10 molecules of DNA will be replicated on another copy of chromosome which is identical to the template. This chromosomes are called SISTER chromatids i.e. replicated chromosome. Each sister chromatids are held together at the centromere and are considered one individual chromosome until they separate during anaphase stage.

Hence, at the Prophase stage, before separation, each sister chromatid (replicated chromosome) is considered as one chromosome. Thus, in the mustard plant with 10 chromosomes, it will possess 10 sister chromatids or chromosomes at the Prophase stage.

N.B: When sister chromatids separate during anaphase stage, they will be regarded as individual chromosomes.
