Answer:
C - Animals competing with each other
Explanation:
C is the only one that doesn’t give evidence of evolution
A shows the similarities between the skeletons in different animals. This can help scientists see what organisms have similar structures and what animals they could have evolved from
B shows what organisms could share a common ancestor. Homologous means that the organisms have the same structure in some part of them. Vestigal means the organism has a part to it’s body that is useless. This easily shows what organisms could have a common ancestor
D shows how animals could have evolved from living in the water to being able to survive on land. Pretty self-explanatory
Animals have always competed with each other, so that doesn’t give any evidence of evolution

the answer is B
Explanation:
i took this class last year
When the nursery at the hospital caught on fire, everybody rushed out with a baby. Unfortunately, after the fire was put out, the babies were in the wrong cribs. Fortunately, the hospital could type all the babies blood types.
Baby#1 was type O
Baby#2 was type B
Baby#3 was type AB.
1. Mr and Mrs jones both had type A blood. Which baby was theirs?
2. Mr and Mrs Williams had types AB and O blood. Which baby was theirs?
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.

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.
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.
MEANING:
Cancer is bad for your body. periodt.

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.
Thus, 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.

A disaster wipes out 50 percent of a small population of birds. Prior to the disaster, about half the birds had a green wing patch and half had a blue wing patch. Several generations after the disaster, only 10 percent have a blue wing patch, and 90 percent have a green wing patch. What do you infer happened, and why?
Answer:
The correct answer is - genetic drift takes place due to disaster in favor of a green wing patch.
Explanation:
In this given scenario there is disaster happened that wiped out 50% of a population of birds in which half had green wings and the rest half had blue wing birds before the catastrophe.
Due to this sudden catastrophe, the genetic drift occurred and also reduced the population to half and the ratio of both types of birds changed and favored the green wings as they are better adapted for the new conditions.

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).

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.
