2. We see an enormous diversity of eyes in Kingdom Animalia. Until recently it was postulated that eyes must have evolved at least 40 times independently. Explain how the discovery of Pax6 (and its homologs such as eyeless ) has overturned this idea in favor of genes for eye development being present in an ancestor to all bilateral organisms.
Answer:Using the mouse Pax6 gene as a baseline, determine the similarity of the homologous genes from the unknown species.
For each unknown species, determine the number of nucleotides that are different from the nucleotides found in the mouse sequence. There are 60 nucleotides in each sequence. To determine the percent similarity, subtract the number of different nucleotides from 60, divide the result by 60, and multiply by 100.

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.
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.

Joshua is studying about environmental impacts. He has learned about companies polluting the groundwater in most nations. Which example would be categorized as the main source for groundwater?
Answer:
Groundwater
Although this may seem surprising, water beneath the ground is commonplace. Usually groundwater travels slowly and silently beneath the surface, but in some locations it bubbles to the surface at springs. The products of erosion and deposition by groundwater were described in the Erosion and Deposition chapter.
Groundwater is the largest reservoir of liquid fresh water on Earth and is found in aquifers, porous rock and sediment with water in between. Water is attracted to the soil particles and capillary action, which describes how water moves through a porous media, moves water from wet soil to dry areas.
Aquifers are found at different depths. Some are just below the surface and some are found much deeper below the land surface. A region may have more than one aquifer beneath it and even most deserts are above aquifers. The source region for an aquifer beneath a desert is likely to be far from where the aquifer is located; for example, it may be in a mountain area.
The amount of water that is available to enter groundwater in a region is influenced by the local climate, the slope of the land, the type of rock found at the surface, the vegetation cover, land use in the area, and water retention, which is the amount of water that remains in the ground. More water goes into the ground where there is a lot of rain, flat land, porous rock, exposed soil, and where water is not already filling the soil and rock.
The residence time of water in a groundwater aquifer can be from minutes to thousands of years. Groundwater is often called “fossil water” because it has remained in the ground for so long, often since the end of the ice ages.

Which statement accurately describes radioactive dating?
Answer:
where is the statement (i will just give you some info coz i dont know what to answer <3)
Explanation:
We have rocks from the Moon (brought back), meteorites, and rocks that we know came from Mars. We can then use radioactive age dating in order to date the ages of the surfaces (when the rocks first formed, i.e. when the lava cooled and crystallized). We also have meteorites from asteroids and can date them, too.
Autosomal Dominant Compelling Helioopthalmic Outburst (ACHOO) Syndrome is characterized by uncontrollable sneezing in response to the sudden exposure to bright light, typically intense sunlight. ACHOO syndrome is inherited in an autosomal dominant manner. If a heterozygous father has children with a recessive mother predict the outcome of their offspring. Using the allele (A) for dominant and (a) for recessive, identify the following using complete sentences:
Father genotype (1 point)
Mother genotype (1 point)
Possible offspring genotypes (1 point)
Possible offspring phenotypes (1 point)
Possible offspring percentage breakdown (1 point)
The father’s genotype would be Aa. As the mother is recessive, her genotype would be aa.
Below I have attached a Punnett square I made for the genotypes of the offspring. The possible phenotypes could be sneezing uncontrollably as a result to light exposure and also wincing / squinting at the sight of bright light. The percentage that the offspring would have ACHOO Syndrome is 50%, which means there is also a 50% chance they wouldn’t have ACHOO Syndrome. The phenotypes the children could also experience as a result of not having ACHOO Syndrome could involve not sneezing uncontrollably when around bright light, but I can imagine them squinting their eyes at light instead as that’s a natural thing people do, but they wouldn’t sneeze unlike those with ACHOO Syndrome.

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).
