Answer:
Relative dating is the answer. It is the method for estimation of the age of an ancient materials by comparing it to another material's age.
Explanation:
Prior to the radioactive dating technique which could do absolute prediction of the age of any rock or event layers, this relative dating method is used by the scientists. The technique of Relative dating could tell the scientists the order of the rock layers and events. It is based on the fact that the more older the rock layer more deeper it would be. The less older rock layer would be less deeper. This procedure could not be used for absolute dating.
Yes.
Explanation:
The Yellowstone river ecosystem is a disrupted ecosystem indeed.
Answer:
Proportion of offspring to have a red coat is
Explanation:
Gametes produced by AaBb animals are AB, Ab, aB, ab
Cross between two AaBb animals would be as follows
AaBb * AaBb
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
Out of the 16, offspring the one with genotype Aabb and aabb will have red color
There are 2 Aabb and one aabb offspring.
Thus, out of 16, 3 offspring are red in color
Proportion of offspring to have a red coat is
Answer and explanation:
That's because the upper part of your nose isn't open to receive the chemicals that trigger the olfactory receptors (those inform your brain and create the sensation of flavor).
The right answer is polarity.
In chemistry, polarity is a characteristic describing the distribution of negative and positive charges in a dipole. The polarity of a bond or a molecule is due to the difference in electronegativity between the chemical elements that compose it, the differences in charge that it induces, and to their distribution in space. The more the charges are distributed asymmetrically, the more a bond or molecule will be polar, and conversely, if the charges are distributed in a completely symmetrical manner, it will be apolar, that is to say non-polar.
Polarity and its consequences (van der Waals forces, hydrogen bonding) affect a number of physical characteristics (surface tension, melting point, boiling point, solubility) or chemical (reactivity).
Many very common molecules are polar, such as sucrose, a common form of sugar. The sugars, in general, have many oxygen-hydrogen bonds (hydroxyl group -OH) and are generally very polar. Water is another example of a polar molecule, which allows polar molecules to be generally soluble in water. Two polar substances are very soluble between them as well as between two apolar molecules thanks to Van der Waals interactions.
