A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds.
Answer:
A
Explanation:
I think its A but it can also be made to condense into a liquid
Answer:
25%
Explanation:
We have 2 independent genes with 2 alleles each: L/l and W/w
- W_: whiskers
- ww: no whiskers
- L_: long whiskers
- ll: short wiskers
Individuals with short whiskers will have the genotype <em>WWll </em>or <em>Wwll</em>.
<u>A cross between a rat heterozygous for both genes and a homozygous recessive rat is done:</u>
<h3>WwLl x wwll</h3>
-The homozygous rat will produce only <em>wl </em>gametes.
-The heterozygous rat will produce the following gametes: <em>WL</em>, <em>Wl</em>, <em>wL</em>, <em>wl</em>.
If you do a Punnett Square, you'll get that 25% of the offspring will be WwLl and will have short whiskers.

calibrated to test and see if the temperature correctly
4. Large, circular lily pads are able to float on the water's surface.
Answer: cohesion
Cohesion mean that water attracted to another water. This force will make the water to form a surface tension in the lake. Water lily has a wide and thin leaf which makes it giving a low force per area. If the force applied on the surface is not bigger than surface tension, the leaf will stay float above the water. Surface tension also the reason water spider could walk on water.
5. The temperature of the water is about 5°C, while the temperature of the air is about 21°C.
Answer: heat capacity
Water has high heat capacity. High heat capacity mean that the water will not be easily become cold or hot. It will need more energy to increase/decrease the temperature of the water. This is why the water could keep its temperature much lower than the atmosphere. This will protect the organism inside the water from an extreme temperature change.
