Answer:
4.index fossils, intrusions, and cross-cutting relationships
Explanation:
There are various geologic features or phenomenon that determines the relative ages of rocks . This geologic features or events includes index fossils , intrusions, cross cutting relationship etc. Note relative ages of rock does not give the actual ages oft the rocks but instead compares the ages of these rocks. Knowing the relative ages of rocks, one can decipher which rock is older or which one is younger. The geologic features give details on the sequence of event that happens through the formation.
Like the principle of cross cutting relationship states that the geologic feature which cut across or intrudes another geologic feature is younger than it surrounding rock.
Index fossils are remains of organisms that are widely spread. The deposition of this remains can give the sequence for deposition of the surrounding rocks which these fossils are found.
Intrusions occurs when geologic features like plutons invades another rock body. Geologically, the plutons will be younger than the surrounding or host rock.
<span>China is a desirable destination for immigration from surrounding countries. People who come to China as immigrants for work contribute to the growth of the population. People from other countries are replacing the native population faster than new births.</span>
Answer:
<em>Evidence from the geological record is consistent with the physics that shows that adding large amounts of carbon dioxide to the atmosphere warms the world and may lead to: higher sea levels and flooding of low-lying coasts; greatly changed patterns of rainfall2; increased acidity of the oceans 3,4,5,6; and decreased.</em>
Answer:
True breeding
Explanation:
One of the main reasons behind the success of Mendel's experiments was that he started the experiments with pea varieties that were true breeding. It is important to understand what a true breeding variety is, it is a plant or organism that is homozygous for a certain trait, in Mendel's case, the pea varieties were homozygous for seven traits, which are : seed coat tint, pod shape, seed shape, flower color, flower location, unripe pod color, and plant height. It means that the varieties contained two similar alleles of genes for these traits in pea plant varieties he chose. Due to the true breeding nature of these traits, the parent plants produced offspring that showed the phenotype just like their parents.
For example:
Here is a cross between plant with yellow flower with another plant containing yellow flower.Suppose allele for yellow is Y and allele for green is y. Let us see what happens in this breeding:
Parents: YY X YY
Offspring: YY
Again cross between offspring: YY X YY
Offspring: YY
This is true breeding in which offspring contain phenotype of parent in many successive generations.
Hope it helps!

Incorrectly. Because he has no idea wether the ants do it out of fear or other emotion (I dont think ants have the mental capacity to process emotion). He does'nt observe the ants are in fear he infers or guesses that they are.
