Relative dating techniques have been around for hundreds of years. How did newer absolute dating techniques change the way we look at geologic cross sections?
Question 17 options:
It allowed us to put geologic cross sections in better order
It allowed us to put a formation date on some geologic cross sections
It allowed us to disprove the existence of land bridges
It allowed us to start using the idea of superposition
Answer:
It allowed us to put a formation date on some geologic cross sections
Explanation:
Absolute dating techniques is an improvement on the older relative dating techniques which only give order of past events but with newer absolute dating techniques, those chronological events are sampled and analysed and more accurate numerical ages assigned to them.
This newer technique has vastly improved the way archaeologists find the age of ancient relics and geologists, rocks.

Since monotremes can lay eggs, why aren't they classified as birds?
-- Explanation NOT multiple choice question --
Answer: They aren't classified as birds because monotremes are mammals, unlike birds. They are referred to as mammals because they have mammary glands responsible for manufacturing and producing milk. Birds cannot do this.
Monotremes, like the Duck-billed Platypus, are not referred to as birds because they lactate, which is a function only possible with mammals, not avians.
How does surface tension force the surface of water to curve
Answer:
the molecules at the surface are being pulled by other molecules. The pulling forces the water to curve. ... The positive hydrogen ends of one water molecule attract the negative oxygen ends of nearby water molecule.
Explanation:
Surface tension forces the surface of water to curve due to its tendency to reduce the surface area of water.
The surface tension of a liquid is in itself a tangential force acting parallel to the surface of the liquid due to the cohesive force of attraction between the molecules of the liquid.
The highly cohesive nature of water molecules means that the molecules at the air/water interface are more stuck together, creating elastic-like surface tension on the water. Thus, the water surface curves inward forming a concave shape.
In other words, the cohesive force of water molecules causes surface tension which in turn causes the surface area of water to reduce or curve inward.

What is required for LIGHT DEPENDENT reactions to occur in plants?
Answer: In light-dependent reactions, the energy from sunlight is absorbed by chlorophyll and converted into chemical energy in the form of electron carrier molecules like ATP and NADPH. Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts.
Explanation:
The light dependent reaction mainly include sunlight, chlorophyll, thakaloids.
Light-dependent reactions
When sunlight hits a molecule of chlorophyll.The excited photon that are present in light also excites an electron which leaves the chlorophyll molecule.These electron then travel travels along the thylakoid membrane via a series of carrier proteins.This reactions convert light energy into chemical energy, also known as photosynthesis.
Plant by the process of photosynthesis collect energy from the sun and break down water molecules to produce ATP and NADPH.
These two energy-storing molecules are then used in the light-independent reactions and maintain the cycle. some of these energy get used by the plants for make the food.
Therefore, the light dependent reaction mainly include sunlight, chlorophyll, and thakaloids.

Which of these factors is involved in earthquake formation?
plates getting larger
rocks breaking
stress that decreases
faults that remain stationary
Answer:
rocks breaking
Explanation:
Breaking rocks is one the factors that is involved during the formation of an earthquake. As rock breaks, there is a sudden release of energy into the surrounding.
When a rock breaks, it is said to be fractured. Such rock fracturing that involves movement of the earth leads to the formation of earthquake. In this process, there is a sudden burst of seismic waves into the environment. Surface waves will cause the damage on the earth surface. The basis of earthquake formation is ability of rocks to break and release a sudden burst of energy.Answer:

Explain what occurs between water molecules in hydrogen bonding
Answer:
The molecules are attracted to their less negative side.
Explanation:
A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other.
The Oxygen in the water molecule will share or the hydrogens lone atom leaving the hydrogen with a more positive charge like in the picture I've added. This happens with all water molecules leaving the oxygen with more electrons and ultimately the more negative side. And positive and negative forces attract, so the now "positive" hydrogens will bond with the now "negative" oxygens. They form bonds using polarity, and use a very strong dipole dipole effect.

If a DNA sequence is A-T-G-A-C, write the sequence of base pairs that would pair with it.
Answer:
T-A-C-T-G
Explanation:
Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.
Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.
Deoxyribonucleic acid is an essential molecule that comprises nucleotides purines and pyrimidines.
The six-membered nitrogen-containing ring joined with the imidazole ring is called purines whereas, the pyrimidines are the six-membered nitrogen ring.Purines ascertained in the DNA and RNA are adenine and guanine.Pyrimidines found in the DNA are cytosine and thymine whereas, in the RNA cytosine and uracil is found.The sequence of the base pair formed from the DNA sequence
A-T-G-A-C will be:
T-A-C-T-G
The adenine always base pairs with thymine.The purine guanine always pairs with the pyrimidine cytosine in the case of DNA sequences.
Therefore, the sequence formed will be T-A-C-T-G .

Plant communities change over time. What is the difference between primary and secondary succession?
Answer:
Answered below
Explanation:
Primary succession occurs in an environment that is not habitable and is newly formed. Pioneer organisms are organisms which start to colonize these environments for the first time.
Secondary succession on the other hand is an ecological succession taking place in an environment or ecosystem that was disrupted but is then recolonized by other organisms.
