Describe the fossils found in the top layers of the Grand Canyon.
Answer:
Sedimentary fossils/rocks
Explanation:
The sedimentary rocks exposed throughout the canyon are rich with marine fossils such as crinoids, brachiopods, and sponges with several layers containing terrestrial fossils such as leaf and dragonfly wing impressions, and footprints of scorpions, centipedes, and reptiles. Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.

What are the DNA base pairs?
Need asap
Answer:
I hope i helped
Explanation:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, "Watson–Crick" base pairs (guanine–cytosine and adenine–thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired structure provides a redundant copy of the genetic information encoded within each strand of DNA. The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding proteins can recognize specific base-pairing patterns that identify particular regulatory regions of genes.

How do ecosystems return to normal after a flood?
This really depends on the ecosystem, as each ecosystem may respond differently.
Explanation:
How an ecosystem responds is going to depend on the ecosystem, as each ecosystem may respond differently, and also on the extent and magnitude of the natural disaster. It takes ecosystems a long time to return to semi-normal conditions it can take up to 200 years for a forest to regrow after a huge fire. and that doesn't include the animals displaced/killed in the disaster.

Where do spindle fibers come from
Spindle fibers are formed from microtubules with many accessory proteins which help guide the process of genetic division. Each spindle fiber forms during cellular division near the poles of the dividing cell. As they extend across the cell, they search for the centromere of each chromosome

Temperatures are low at the top of a thunderstorm cloud. Based on this evidence, which of the following commonly forms at the top of a thunderstorm cloud?
A. acid rain
B. air molecules
C. ice
D. oxygen
Thunderstorm cloud have low temperature at the top of the them, ice is formed in the thunderstorm. Thunderstorm clouds are the rain-bearing clouds. Thus, the correct option is C.
What is Thunderstorm cloud?Thunderstorm clouds are the rain-bearing clouds that also produces lightning. Thunderstorms are dangerous. Every type of thunderstorm produces lightning.
The thunderstorm clouds are menacing looking multi-level clouds, with heights extending up to the sky in towers or plumes. More commonly known as thunderclouds. It is the only cloud type that produces hail, thunder and lightning.
There are three basic ingredients required for the development of thunderstorm, which are moisture, an unstable atmosphere, and some way to start the atmosphere moving. However, the moisture is necessary component to produce the thunderstorm clouds and precipitation.
Therefore, the correct option is C.
