How long does it take a bone to become a fossil?
Answer:
Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years.

What is the structure that breaks the spindle fiber into 2?
Help !!
Answer:
The centromeres
Explanation:
The KINETOCHORE is the cellular structure that breaks the spindle fiber into TWO.
The kinetochore is a structure that associates the duplicated chromatids in eukaryotic cells to spindle microtubules during cell division (either mitosis or meiosis).
The kinetochore forms at the centromere of the chromosomes.
The kinetochore is a disk-shaped structure made up of more than 100 different proteins, especially constitutive centromere-associated network (CCAN) proteins.
In conclusion, the KINETOCHORE is the cellular structure that breaks the spindle fiber into TWO.

Explain the difference between the structure of a simple leaf and a compound leaf, and how such differences can be used within identification systems to determine the species of a plant.
Answer:
Explanation:
A simple leaf is a single leaf that is never divided into smaller leaflet units. It is always attached to a twig by its stem or the petiole. A compound leaf on the other hand is divided to the midrib, forming two or more distinct blades
Answer:
Simple leaves have an undivided leaf blade and there is an axillary bud at the base of the leaf. However, compound leaves have divided leaves. Thus, a compound leaf has more leaflets than a simple leaf. Furthermore, there is no axillary bud present at the base of each leaflet.
Explanation:
Microorganisms also exist in the fossil record, but they’re rarer than other types of fossils. The most common fossils form from hard body parts, such as bones, teeth, and shells. Why do you think these fossils are more common than fossils of other soft tissues or microorganisms?
Answer:
Organisms decompose more quickly when they are in contact with oxygen. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.
Explanation:
Answer:
When the decomposing process of an organism is taking place, it is breaking apart the nutrients within the organism in order to return it to the Earth in itself. When an organism buried at a quicker pace it cause the decomposing process to last at a longer time, which in term makes the chance of it being better preserved in at the same time. Due the bones of different organisms we are able to analyze the organism that has decomposed, because once that time of decomposition is complete we will be able to see the fossils of the organism and the evaluate the categorization of the specific organism that a scientist is examining.

Rosa drew a diagram to compare substitution mutation and insertion mutations. What label belongs in the area marked "Y"?
Answer:
Hey There!
_____________________________________
Answer:
_____________________________________
Mutations:
Mutations are the changes produced in the nucleotide sequence of the genome.
There are four main types of mutations
Substitution
Insertion
Deletion
Duplication.
_____________________________________
DELETION:
A small segment of chromosome mat be missing. This condition is known as deletion.
For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.
_____________________________________
DUPLICATION:
In this condition, a part of chromosome present in exec ess to the normal chromosome.
For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.
_____________________________________
SUBSTITUTION MUTATION:
Substitution is a type of mutation where one base pair is replaced by a different base pair.
For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.
INSERTION MUTATION:
In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.
For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.
_____________________________________
Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid. Option A is correct because B and D are wrong as increase in number of bases and decrease in number of bases is because of deletion and duplication mutations here it asks for substitution and insertion mutations. C is wrong as In mutation there is always a change in bases or chromosome. So all the other choices seem incorrect as it is asking for substitution and insertion the base pair changes which results in the change in type of amino acid.

What happens when green plant leaves absorb energy from the Sun?
A. Plants get too warm.
B. Sugars are produced
C. More green color is produced.
D. Green leaves turn red.
Answer:B. Sugar are produced
Explanation: when green leaves absorb sunlight it is converted to Energy by photosynthesis.
Answer:
I'm pretty sure it's C.
Explanation:
Plants don't get to warm unless they don't have oxygen, sugars are produced, but only during all of photosynthesis, and green leaves don't turn red unless the season is changing. But sun light gives chlorophyll what it needs to produce that green color. Therefor, C is your answer.

I’m working on a cell project that is focusing on the nucleus and I have to find a theme song for it. Any suggestions about songs that might relate to the function of a nucleus?
Answer:
https://youtu.be/tRo73dzVfuo
A good song that could serve as a theme song for your cell project is;
The Nucleus Song, sung by Megan and SarahThe song above can serve as a good background for your cell project. It can be gotten from the mainstream video blog under the name Craigdet.
This song is a good choice because its lyrics mention the various parts of the cell, like the ribosomes, endoplasmic reticulum, cytoplasm, etc., and their functions.
It also mentions and displays the nucleus and its role in the cell. The song is educative and entertaining. It will be a good fit for your project.
