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.

What do all members of the swine species always have in common? They always have the same number and kinds of chromosomes. They are always preyed upon by the same predators. They always occupy the same habitat at the same time. They always occupy the same position in the food web no matter where they live.
Answer:
Members of the swine species always have the same number and kinds of chromosomes
Explanation:
The swine species always have their food habits in common. They are omnivorous and they also due to ancestry have the typical type of genes and chromosomes inscribed in it. Hence swine are used in research industry nowadays like dogs and monkeys.
Wild boars, hogs and pigs all have just small differences externally. Their anatomy and physiology are identical. They are all mammals. They are highly intelligent and talented ones. They have their physiology identical to ours which helps in research scientist to experiment and finds cure for human.
Answer:
biological definition of species, which works for sexually reproducing organisms, is a group of actual or potential interbreeding individuals. There are exceptions to this rule. Many species are similar enough that hybrid offspring are possible and may often occur in nature, but for the majority of species this rule generally holds. The presence in nature of hybrids between similar species suggests that they may have descended from a single interbreeding species, and the speciation process may not yet be completed.
Given the extraordinary diversity of life on the planet there must be mechanisms for speciation: the formation of two species from one original species. Darwin envisioned this process as a branching event and diagrammed the process in the only illustration found in On the Origin of Species (Figure 1a). Compare this illustration to the diagram of elephant evolution (Figure 1b), which shows that as one species changes over time, it branches to form more than one new species, repeatedly, as long as the population survives or until the organism becomes extinct.
Explanation:
For speciation to occur, two new populations must be formed from one original population and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed. Biologists have proposed mechanisms by which this could occur that fall into two broad categories. Allopatric speciation (allo– = “other”; –patric = “homeland”) involves geographic separation of populations from a parent species and subsequent evolution. Sympatric speciation (sym– = “same”; –patric = “homeland”) involves speciation occurring within a parent species remaining in one location.
Biologists think of speciation events as the splitting of one ancestral species into two descendant species. There is no reason why more than two species might not form at one time except that it is less likely and we can conceptualize multiple events as single splits occurring close in time.
Allopatric Speciation
A geographically continuous population has a gene pool that is relatively homogeneous. Gene flow, the movement of alleles across a species’ range, is relatively free because individuals can move and then mate with individuals in their new location. Thus, an allele’s frequency at one end of a distribution will be similar to the allele’s frequency at the other end. When populations become geographically discontinuous, it prevents alleles’ free-flow. When that separation lasts for a period of time, the two populations are able to evolve along different trajectories. Thus, their allele frequencies at numerous genetic loci gradually become increasingly different as new alleles independently arise by mutation in each population. Typically, environmental conditions, such as climate, resources, predators, and competitors for the two populations will differ causing natural selection to favor divergent adaptations in each group.

3. Mr and Mrs Wilson had types B and A blood. Which baby was theirs?
Answer:
baby #1 goes to family 2
baby #3 goes to family 1
and baby #2 goes to family 3
Explanation:
its simpler then it looks☺
Baby with blood group O belongs to Mr. and Mrs. Jones, baby with blood group B belongs to Mr. and Mrs. Williams, and baby with blood group AB belongs to Mr. and Mrs. Wilson.
What is a blood group?
Blood group or blood type is the classification of the blood cells into different classes on the basis of presence or absence of antibodies and antigens on the membrane of the blood cells.
The alleles which can be formed in case of Mr. and Mrs. Jones are AA or Ai type. These alleles can only result into formation of an offspring with blood group O or A. Similarly, the possible combination of alleles in case of Mr. and Mrs. Williams is AB and ii, these combinations will result into development of offspring with blood group A or B. In case of Mr. and Mrs. Wilson, the possible combinations of alleles are Ai or AA and Bi or BB, which results into formation of offspring with blood group AB.
This can also be represented through punnett square.

fossils are taken as the strongest evidence so far regarding the evolution of organisms. justify this statement
Answer:
No present empirical evidence supports the idea of that natural causes can result in an increase of complexity. The idea that descent with modification has happened in the past is supported by the fossil record. This makes the fossil record the strongest evidence for Darwin's theory of evolution
Explanation:
Fossils are defined as the preserved remains or traces of animals, plants, and other organisms from the past that are important evidence for evolution because they show that life on Earth was different from what was once found on Earth.
What are Fossils?A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA.
The totality of fossils is known as the fossil record. These are the preserved remains of plants and animals whose bodies were buried in sediments such as sand and mud at the bottom of ancient seas, lakes and rivers, including any preserved traces of life which are usually over 10 000 years old.
The different types of fossils include:
1. Petrified fossils
2. Mold and cast fossils
3. Carbon film fossils
4. Trace fossils
5. Reserved remains, etc.

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).

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!
Genes determine the______ of organisms.
Explain how errors in DNA replication and environmental factors cause genétic variation
DNA replication is a truly amazing biological phenomenon. Consider the countless number of times that your cells divide to make you who you are—not just during development, but even now, as a fully mature adult. Then consider that every time a human cell divides and its DNA replicates, it has to copy and transmit the same sequence of 3 billion nucleotides to its daughter cells. Finally, consider the fact that in life (literally), nothing is perfect. While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence. Fortunately, most of these mistakes are fixed through various DNA repair processes. Repair enzymes recognize structural imperfections between improperly paired nucleotides, cutting out the wrong ones and putting the right ones in their place. But some replication errors make it past these mechanisms, thus becoming permanent mutations. These altered nucleotide sequences can then be passed down from one cellular generation to the next, and if they occur in cells that give rise to gametes, they can even be transmitted to subsequent organismal generations. Moreover, when the genes for the DNA repair enzymes themselves become mutated, mistakes begin accumulating at a much higher rate. In eukaryotes, such mutations can lead to cancer.

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.
