Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.

Genes and Proteins in Hemophilia
Genetic researchers at Bay Medical Company are working to improve treatments for hemophilia. Currently, they are investigating the possibilities of gene therapy, which involves changing a person’s genes so that that person no longer has hemophilia. In order to help Bay Medical Company with their research, read the passage below and then answer the question.
Genes are instructions for proteins. Your traits are determined by the kinds of proteins your body makes. For example, when you get a cut, clotting factor proteins connect to form scabs. People with hemophilia do not have a version of the gene with the right instructions for making clotting factor VIII protein. Without the right instructions, their cells can’t make the proteins needed to form scabs. Healthy people have at least one copy of the gene that provides the right instructions for making all of the clotting factor proteins.
If genetic researchers found a way to change a person’s genes, would they be able to cure hemophilia? Why or why not?

Explain how convection current works in order to form wind.
Answer:
A convection current would work in order to form wind by having a lower surface pressure. That lower surface pressure would then create a particular pressure gradient which tries to initially correct itself due to that pressure. It corrects itself by having more air going from higher pressure to lower pressure due to a rising of air.
Moreover, we can understand this by understanding convection first. As we know, convection happens when heat around the Earth is uneven. The air that we have around Earth heats up according to how the Earth revolves and how fast it heats and that particular portion of the atmosphere will initially act faster and heat up faster due to the fast spread of heat of what is under Earth.
volume increases = pressure drop
-> due to the fact that air masses do not actually mix, the amount of air remains will naturally remain constant and the volume would eventually increase, another way of saying this is - Boyle's Law.
warmer air = drop in pressure and lower pressure than the surrounding air due to the heat of air being warmer (denser than cold air).
- difference in pressure called a pressure gradient
- creates a force called the pressure gradient force -> air always wants to move from an area of high pressure to low pressure due to that gradient.

9. A section of a topographic map is shown below. X- 1600 1500 1400 1300 Contour interval: 20 m 1200- What is the difference in elevation in meters between Point X and Point Y on the map?
The difference in elevation in meters between the points X and Y is 360.
Explanation:
On the presented map we can see that the relief is depicted with contour lines. The contour lines are marked with their elevations, or rather the main contour lines are, every fifth one. We also have the contour interval, which is 20 meters, thus giving us the basis so that we can find the difference in elevation between any points on the map.
What we know for sure from the map is:
the elevation is increasing from southeast toward northwestthe difference in elevation between the contour lines is 20 mthe difference in elevation between the main contour lines is 100 mPoint X is marked on the contour line of 1,600 m. Point Y is marked on the second contour line between the 1,200 m and 1,300 m contour lines, thus:
2 x 20 = 40
So we have 1,240 m. Having the elevations of the two points, we only need to take the lower value from the larger value:
1,600 - 1,240 = 360 m
So we get a result of 360 m of difference in elevation between the points X and Y.

When an offspring receives one green allele (G) and one red allele (R), the result id a green leaf with red veins
Answer:
GR
Explanation:
the genotypes of the parents are homozygous dominant GG and RR so when they fertilise they give all GR offsprings
The genotype of the plant is GR. This is because the offspring received green allele (G) as well as red allele (R), and both results showed up as the plant is green with red veins.
When something gives up alleles to its offspring, the parents originally have alleles like Aa and Bb. When offspring is created, you can use the Punnett square to guess which alleles will be passed on. In the plant’s case, G and R were passed on.

6. What did Watson, Crick, and Franklin discover about the structure of DNA?
7. How did Watson, Crick, and Franklin's work reiterate Chargaff's findings?
1. adenine

4. X-ray crystallography is a technique used to learn more about the three-dimensional structure of biological molecules. In x-ray crystallography, a molecule (for example, DNA) is crystallized. Then, x-ray beams are directed onto the molecular crystal. The pattern of diffraction, or bending, of the x-rays provides information about the physical properties of the molecule. Rosalind Franklin used x-ray crystallography to investigate the three-dimensional structure of DNA.
5. Watson and Crick were interested in learning more about the physical structure of DNA. They had come up with several hypotheses about how DNA could be structured, but they needed more concrete evidence of the molecule's structure. Rosalind Franklin's Photo 51 provided important information to Watson and Crick as they worked on a model of the three-dimensional structure of DNA.
6. Photo 51 confirmed that DNA is a double helix. Watson and Crick's model of DNA included that it is antiparallel, and that each base pair is held together by hydrogen bonds. The DNA chain is comprised of an outer backbone alternating between the sugar deoxyribose and phosphate groups. The base pairs, which are held together by hydrogen bonds, are located on the inner portion of the double helix.
7. Chargaff found that the number of adenine nucleotides was always roughly the same as the number of thymines, and the number of cytosines was about the same as the number of guanines. This provided the insight that in the DNA double helix, A selectively bonds with T, while G bonds with C. This explains why Chargaff consistently found that the number of As and Ts, and the number of Cs and Gs, were the same in his studies.

1. How can hanging clothes reduces the greenhouse gas emissions?
2. What is carbon footprint?
3. What is the difference between finite and infinite?
4. How does using a fan lowers the greenhouse gas emissions?
5. What is mitigating?
6. How can sweeping minimizes noise pollution?
7. How does planting can conserve our natural resources?
Answer:
Explanation:
1) Hanging clothes to dry reduces electricity use and greenhouse gas emissions and makes clothes last longer.
2) The carbon footprint serves as an indicator to compare the amount of greenhouse gases emitted over the entire life cycle from the production of a good or service along the supply chain to its final consumption
3) The word 'Finite' itself describes that it is countable, and the word 'Infinite' means it is not finite or uncountable.
Answer:
Explanation:
1.) Using hanging clothes instead of using any machine(dryer) reduces the emission of gases and uses natural ways (sunlight, wind) to dry them up.
2.) Carbon footprint can be defined as the amount of greenhouse gases especially carbon dioxide (CO2) and methane emissions, that relate to daily human activities.
3.) If the no. of elements are countable then they are said to be finite, while if the no. of elements are uncountable then they are said to be infinite.
4.) Fans help to evaporate moisture from the skin, providing a cooling effect as it creates breezes instead of cooling it, while
Air conditioners remove heat from the air by using energy-intensive refrigeration cycles,
Thus fan helps to reduce greenhouse gas emissions.
5.) Mitigating refers to the act of reducing or minimizing the negative impacts of a particular issue or problem.
