Answer:

1) internal response

2) external stimuli

Explanation:

flight or fight response is a psychological response when a threat occurs, the danger is an external stimuli because it happens in the organism's surroundings.

4. Consider the following reaction:
Lyrx [107]

Answer:

High temperatures

Explanation:

NaHCO₃ (8) + HCH,O₂ (aq) → H₂O (l) + CO₂ (g) + NaC,H₃O₂ (aq)

As the flask gets cooler to the touch as the reaction proceeds, the reaction is endothermic. This means that ΔH is positive (ΔH>0).

As a gas is formed (bubbles are formed), ΔS is positive (ΔS>0).

<em>In terms of ΔG:</em>

  • ΔG = ΔH - TΔS

<em>In order for the reaction to be thermodynamically favorable, ΔH has to be negative</em>, thus:

  • The reaction is favorable if TΔS > ΔH.

The greater the temperature, the easier it would be for TΔS to be greater than ΔH.

wariber [46]

Given the partial record of the experiment, the information that should be recorded in the last column of the table is B. Time is taken by the glass surface to dry.

<h3>What is an intermolecular force?</h3>

These are forces of attraction between atoms, molecules, and ions when they are placed close to each other.

Intermolecular forces are electrostatic in nature, and this means that they arise from the interaction between positively and negatively charged species.

Hence, an intermolecular force acts between molecules and their examples are London dispersion forces, dipole-dipole interaction, ion-dipole interaction, and van der Waals forces.

The complete question

An experiment was conducted to determine if the intermolecular forces in two liquids affect their boiling points. Each liquid was sprayed on a paper towel. Each paper towel was wiped across a glass table to moisten the surface. The table shows a partial record of the experiment.

Experimental Record

Liquid Intermolecular Forces ?

А relatively strong

B relatively weak

What information should be recorded in the last column of the table?

Time is taken by the liquids to start boiling

Time is taken by the glass surface to dry

two factors that determine wether a molecule is polar are the types of atoms in the molecule and the ____ of the molecule
kolezko [41]

Answer:

Shape

Explanation:

Two factors that determine wether a molecule is polar are the types of atoms in the molecule and the <u>shape</u> of molecule.

Shape and polarity determine which type of compounds is.

if the shape of molecule is symmetric it will non polar. And it will dissolve in non polar solvent. The polar molecules are trigonal in shape.

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion and compound is polar.

The compound having ionic bonds generally have moderate to high boiling points and melting point because of greater electrostatic interaction. Their electrical conductivity are high and these minerals tend to dissolve in water.

Covalent bond:

It is formed by the sharing of electron pair between bonded atoms.  

The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive and compound will polar.

For example:

In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.

If the ectronegativity difference is 0.4 or less than this the compound will be non polar covalent compound and will behave different from polar compound.

During which part of the cell cycle is the duplicated genetic material within the nucleus of a parent cell separated to create t
RideAnS [48]

Telophase because it is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

Hope this helps! Please correct me if I'm wrong :)
