How are alleles represented in genetics?
Biologists refer to dominant alleles as uppercase letters and recessive alleles as lowercase letters when referring to genotype.
What are alleles?Genetics and evolution define an allele as a variant of the same sequence of nucleotides at the same location on a lengthy DNA molecule.
The variant DNA sequences at a locus are known as alleles, and the chromosomal or genomic location of a gene or any other genetic element is referred to as a locus.
Alleles can be identified using just one capital or lowercase letter, two, three, or more letters, or letter/number combinations. Superscripts, subscripts, or both may be present in alleles.
Alleles that are recessive are denoted by lowercase letters, while dominant alleles are denoted by capital letters.
Thus, this way, the alleles are represented.

17. Identify How would the
shuttle's motion change if
there were no gravitational
force between it and Earth?
Answer:
Gravity is one of those things we take completely for granted. And there are two things about it that we take for granted: the fact that it is always there, and the fact that it never changes. If the Earth's gravity were ever to change significantly, it would have a huge effect on nearly everything because so many things are designed around the current state of gravity. Before looking at changes in gravity, however, it is helpful to first understand what gravity is. Gravity is an attractive force between any two atoms. Let's say you take two golf balls and place them on a table. There will be an incredibly slight gravitational attraction between the atoms in those two golf balls. If you use two massive pieces of lead and some amazingly precise instruments, you can actually measure an infinitesimal attraction between them. It is only when you get a gigantic number of atoms together, as in the case of the planet Earth, that the force of gravitational attraction is significant. The reason why gravity on Earth never changes is that the mass of the Earth never changes. The only way to suddenly change the gravity on Earth would be to change the mass of the planet. A change in mass great enough to result in a change in gravity isn't going to happen anytime soon.
Explanation:
But let's ignore the physics and imagine that, one day, the planet's gravity turned off, and suddenly there was no force of gravity on planet Earth. This would turn out to be a pretty bad day. We depend on gravity to hold so many things down -- cars, people, furniture, pencils and papers on your desk, and so on. Everything not stuck in place would suddenly have no reason to stay down, it would start floating. But it's not just furniture and the like that would start to float. Two of the more important things held on the ground by gravity are the atmosphere and the water in the oceans, lakes, and rivers. Without gravity, the air in the atmosphere has no reason to hang around, and it would immediately leap into space. This is the problem the moon has -- the moon doesn't have enough gravity to keep an atmosphere around it, so it's in a near-vacuum. Without an atmosphere, any living thing would die immediately and anything liquid would boil away into space. In other words, no one would last long if the planet didn't have gravity. If gravity were to suddenly double, It would be almost as bad, because everything would be twice as heavy. There would be big problems with anything structural. Houses, bridges, skyscrapers, table legs, support columns, and so on are all sized for normal gravity. Most structures would collapse fairly quickly if you doubled the load on them. Trees and plants would have problems. Power lines would have problems. The air pressure would double and that would have a big effect on the weather. What this answer shows you is just how integral gravity is to our world. We can’t live without it, and we can't afford to have it change. It is one of the true constants in our lives!
HELP!!!! BIOLOGY!!!! 50 POINTS!!!!
A species of frog slowly dies off when its main food source migrates to another area. Migrating toads and lizards begin to expand to the region. This is an example of (3 points)
remaining species living longer due to increased food supply
surviving populations reaching a state of equilibrium due to decreased competition
surviving species exploiting a newly available niche
organisms evolving more slowly as they recover from the loss of diversity
I think is C
Answer:
C
Explanation:
C states that the surviving species exploite a newly available niche. When an animal migrates is trying to find food or more livable conditions. C is true because migrating usually occurs when animals want to find other new places to fit their circumstances or living conditions.
This is an example that states how the surviving species exploit a newly available niche (Option C).
What is a species niche?In biology, the term niche refers to the match between the features of a given species and particular environmental conditions.
The species niche is also used to describe the ecological role of a given species in an ecosystem.A species niche includes both biotic factors (e.g. competition relationships) and abiotic factors (e.g. temperature tolerance).In conclusion, this is an example that states how the surviving species exploit a newly available niche (Option C).

A cell's mRNA loses all of its uracil. What will happen next?
If a cell's mRNA loses all of its uracils, then it will not undergo a protein synthesis or translation process.
as defected mRNA will not be able to form all anticodon thus there is no codon formation takes place for protein synthesis.
What are codon and anticodon?Codon: A codon is a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid.
Anticodon: An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence.
Hence, If a cell's mRNA loses all of its uracils, then it will not undergo a protein synthesis or translation process.

How would you convert a spring into a straight piece of metal using the same approach as topoisomerase in DNA replication?
Answer:
It would be necessary to make small breaks in the spring and then align the pieces, forming a straight piece.
Explanation:
Topoisomerase is the enzyme responsible for unwinding the DNA molecule during replication. To do this, topoisomerase makes small breaks in the DNA molecule, but uses covalent bonds to hold these small pieces of DNA, causing the strands of DNA to pass over each other, aligning in a rectilinear topography.
What is cancer? (please make sure to include mitosis and cell division)
Answer:
Cancer is a disease in which abnormal cells divide uncontrollably and destroy the body tissue. // Putting it into simple words, It’s an error caused in meiosis and cell division.WELL here's what it does to your body... (please read all of it...thank u)
Let's start with what is cancer? Cancer is an uncontrolled growth of abnormal cells in the body. Cancer is caused by a mutation in DNA cells. The DNA inside a cell is packed into a large number of individual genes. Those genes in the cell, each contains a set of instructions telling the cells what types of functions to perform as well as how to grow and divide into more cells. Kind of like a little increased cell factory like system. Errors in the 'instructions' can cause the cell to stop its normal work and functionality and allow a cell to become cancerous.
Soo... gene mutations can instruct healthy cells to allow and naturalize excessive growth or rapid growth in cells to divide. So then all the new cells are infected and mutated. It can also fail to stop unhealthy rapid growth. Basically, cancer cells lose control in the factory and basically keep on spreading and growing an unhealthy amount till it gets deadly. Just kidding but basically thats what it means. AND gene mutations also make "mistakes" when they try to fix DNA errors. Which then are lead to turn into cancerous cells.
Now, what causes gene mutation? Gene mutation can be caused by one of many reasons. Two of the main reasons is being born fresh out your mommas womb. You could be born with a genetic gene mutation you most likely inherited from your parents. OR it could be caused by the enviroment you live in. Causes such as smoking, radiation, obesity, harmones, etc. and a lack of exercise. However, cells contain a mechanism that recognizes when a mistake occurs and repairs the mistake. But occasionally, a mistake is missed... which therefore results in a cell becoming cancerous.

Cancer is bad for your body. periodt.
