Strong sugar solution A Pin holding potato .Potato Pure water -Beaker 1.4.1 State TWO differences between the process investigated in the diagram above and diffusion. 1.4.2 Give ONE planning step that should be considered prior to this Investigation. 1.4.3 Explain the importance of the potato in this investigation.
Answers
1.4.1 Two differences between the process investigated in the diagram above and diffusion:
In the diagram, the process being investigated involves osmosis, not diffusion. Diffusion refers to the movement of particles from an area of higher concentration to an area of lower concentration, while osmosis specifically refers to the movement of water molecules across a semi-permeable membrane.In osmosis, the movement of water molecules occurs in response to the concentration gradient of solute particles, whereas in diffusion, the movement of particles is driven solely by the concentration gradient of the particles themselves.1.4.2 One planning step that should be considered prior to this investigation:
It is important to establish a clear and measurable objective for the investigation. This could involve defining the specific research question or hypothesis that the investigation aims to address. Having a well-defined objective will help guide the experimental design and ensure that relevant data is collected.1.4.3 The importance of the potato in this investigation:
The potato is important in this investigation because it serves as the object of study or the sample material through which osmosis is observed. The potato, being a plant tissue, contains cells with semi-permeable membranes that allow the passage of water molecules but restrict the movement of solute particles. By placing the potato in the strong sugar solution and observing the changes in its weight or texture, one can study the process of osmosis and the effects of water movement across the potato cells. The potato serves as a model system to understand the principles and mechanisms of osmosis in biological systems.for similar questions on sugar solution.

Responses included are:
The heart pumps 2 ounces (71 grams) of blood at every heartbeat. The heart pumps 2,500 gallons (9,450 liters) of blood each day. The heart beats over three billion times in a person’s lifespan. Why does the heart muscles have great elastic strength?The heart is a four-chambered organ that is located in the center of the chest. The two upper chambers of the heart are called the atria, and the two lower chambers are called the ventricles. The atria receive blood from the body, and the ventricles pump blood to the lungs and the rest of the body.
The heart is a vital organ that is essential for life. It is responsible for pumping blood throughout the body, which delivers oxygen and nutrients to the cells and removes waste products. The heart is a strong and resilient organ, but it can be damaged by disease or injury. If the heart is not functioning properly, it can lead to a number of health problems, including heart failure, stroke, and heart attack.

Name three different factors from Your plan. My Planet. , actions or specific human activities that contribute to the negative environmental impact in your selected area.
Answers
In the context of "My Planet" as the selected area, here are three different factors, actions, or specific human activities that contribute to the negative environmental impact:
1. Deforestation: The clearing of forests for various purposes, such as agriculture, logging, and urbanization, has a significant negative environmental impact. Deforestation contributes to habitat loss, biodiversity depletion, soil erosion, and carbon emissions, which exacerbate climate change.
2. Pollution and waste: Human activities that result in pollution and waste generation have detrimental effects on the environment. This includes air pollution from industrial emissions and vehicle exhaust, water pollution from industrial and agricultural runoff, and improper disposal of waste materials. Pollution and waste can harm ecosystems, contaminate water sources, endanger wildlife, and contribute to climate change.
3. Overconsumption and resource depletion: Unsustainable patterns of consumption, driven by excessive demand for goods and resources, have a negative environmental impact. Overconsumption leads to the extraction of finite resources beyond sustainable levels, such as minerals, fossil fuels, and freshwater. It also contributes to the generation of waste, energy consumption, and greenhouse gas emissions associated with the production, transportation, and disposal of goods.
These factors and actions collectively contribute to the degradation of ecosystems, loss of biodiversity, climate change, and other environmental challenges that can negatively impact "My Planet." It is crucial to address these issues through sustainable practices, conservation efforts, and responsible consumption to protect and preserve the environment for future generations.

1) Why does the addition of dideoxynucleotides to the DNA sequencing reaction cause DNA synthesis to stop after the modified nucleotide is added?
A)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'OH group to attach the next nucleotide being added.
B)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'PO4-group to attach the next nucleotide being added.
C)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added.
D)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'PO4-group to attach the next nucleotide being added.
Answers
In Sanger sequencing, once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added. This phenomenon is useful to sequence a polynucleotide chain.
Dideoxynucleotides (ddNTPs) are nucleotide inhibitors of the DNA polymerase, it is for that reason that they are used in Sanger sequencing.
The ddNTPs are similar to natural deoxynucleotides used by cells during ADN replication; however, ddNTPs lack a hydroxyl (OH) group on the 3’ carbon of the deoxyribose.
In consequence, once a ddNTP is added, DNA synthesis cannot progress, thereby this phenomenon can be used to determine the order of nucleotides during the elongation of a polynucleotide DNA chain.
