How did the scientists determine that there was a second victim ?
Scientists use a variety of methods, including physical evidence analysis, eyewitness accounts, the principle of inference, and statistical analysis, to determine facts such as the presence of a second victim.
Explanation:In science, evidence takes center stage in determining facts and conclusions. In regard to determining the presence of a second victim, scientists used a combination of methods. These include analyzing physical evidence, such as marks left on the site of incident, physical remains, or technological instruments used to track physical changes or emittances. In situations related to crime, DNA analysis can serve as an example of such method. Eyewitness accounts, as unreliable as they may be, also contribute evidence. Just as Donald Thomson was falsely identified as the perpetrator due to the victim's confusion between him and the real criminal she saw on television, valid identifications can narrow down possibilities as well.
Another significant method involves the principle of inference. Scientists consider each piece of evidence and draw conclusions based on them, just as was done in the quark hypothesis. Even if these conclusions are not definitive, they provide a launchpad for further investigations and can be revised as techniques become more reliable. Statistics are also of great importance. Through statistical analysis, patterns can be identified, and factors overlooked before can become clear, sometimes altering conclusions radically.

Sarah recently learned that O2 is found in the Earth’s water bodies. She was amazed to know the proportion of O2 found in the ocean differs based on the water temperature. What fact did she find out?
Answer:
She found out that ___A___ parts of the oceans have a higher quantity of dissolved 02, whereas ___B___ parts of the ocean have a lesser quantity of it.
Explanation:
A) Cooler
B) Warmer
Hope this helps:)
Cold water holds more dissolved oxygen than warm water, impacting marine life and ecosystem health in aquatic environments.
The amount of oxygen that water can hold depends on various factors, with temperature being one of the most significant. Generally, colder water can dissolve more oxygen than warmer water. This is because the molecules in colder water are closer together and move more slowly, allowing oxygen molecules from the atmosphere to dissolve and stay within the water more easily.
Conversely, warmer water has molecules that are more spread out and move more quickly, which makes it harder for oxygen molecules to dissolve and remain in the water. Additionally, warm water often experiences increased biological activity, such as photosynthesis by algae and other plants, which can consume oxygen during the process, further reducing the dissolved oxygen levels.
This phenomenon has important implications for aquatic ecosystems. In areas with colder water, such as polar regions or deep ocean currents, there tends to be higher dissolved oxygen levels, supporting a diverse range of marine life. However, in warmer waters, such as shallow coastal areas or regions affected by climate change, lower oxygen levels can occur, potentially leading to oxygen-deprived "dead zones" where marine life struggles to survive.
Understanding the relationship between temperature and oxygen solubility in water is crucial for managing and preserving aquatic ecosystems and the diverse array of life they support.

Plzz help
Reptiles and amphibians are ectothermic, or cold-blooded. They are unable to generate their own body heat and thus cannot regulate their own body temperature.
Mammals and birds are warm blooded, which means they can make their own body heat. They can do this when it's too cold for them to survive outside.
How is it possible that over 20 million living organisms on the planet are made up of only 5 types of nucleotide bases arranged in long chains
It is because of different arrangements of nucleotide bases.
ExplanationThere are only five types of nucleotide basis are present in the genetic material which makes up the all the genetic information of the individuals. These nucleotides are named as Adenine, Thymine, Guanine, Cytosine and Uracil. In all the living beings on the earth, these only five nucleotides are present which decides their behaviour and functions on the earth. These five bases have features to get any arrangements according to the situation. Their different arrangement at the heredity material makes the difference in all living beings regarding their behaviour.
DNA, composed of nucleotide bases, carries genetic information for each organism, leading to the incredible diversity of life on Earth.
DNA (deoxyribonucleic acid) is composed of nucleotides, which are molecules made up of sugars, phosphates, and nucleotide bases. These bases, adenine, thymine, cytosine, and guanine (A, T, C, G), organized in long chains, carry the genetic information for each organism. The diversity and complexity of life arise from the order of these nucleotide bases in the DNA sequences.

why do we need to protect our oceans from pollution
We need to protect our oceans from pollution because it harms marine ecosystems, affects human health and livelihood, and contributes to climate change.
Climate change exacerbates other ocean problems, such as coral bleaching, which affects the rich biodiversity within coral reefs, important nutrients for marine life, and the provision of protein for millions of people. Furthermore, coral reefs serve as natural barriers against disasters like tsunamis, and they greatly contribute to tourism.
Ocean water pollution illustrates that despite their vastness, oceans are highly susceptible to pollution. Trash, including plastics, not only contaminates coasts but can also create hazards for marine animals, leading to entanglement or ingestion of inedible materials. Oil spills, like the incident in the Gulf of Mexico in 2010, can devastate marine species and destroy coastal habitats.
Human activities, driven by our standard of living and neglect of coastal pollution controls, also play a significant role. Runoff from land carries pollution to the sea, compounded by direct waste disposal into coastal waters in certain regions. Plastic pollution is a challenge that could be mitigated by banning single-use plastics and improving recycling programs

What role do red blood cells play in the human body? They protect against injury. They protect against disease-carrying microorganisms. They transport oxygen throughout the body. They aid in blood clotting.
Red blood cells play a huge part in the human body
Red blood cells transport oxygen throughout the body
They are able to carry oxygen because of an important protein called haemoglobin.
Not only does haemoglobin carry oxygen, but it's also responsible for the red color of our blood.
If red blood cells didn't contain haemoglobin the cells wouldn't be able to do their job properly. If this happens we would slowly die
The role that red blood cells play in the human body is that they transport oxygen throughout the body.
Red blood cells, also known as erythrocytes, are the most abundant cell type in the blood. Their primary function is to carry oxygen from the lungs to the body's tissues and return carbon dioxide from the tissues back to the lungs to be exhaled. This oxygen transport is facilitated by haemoglobin, a protein within red blood cells that binds to oxygen.
While red blood cells are not directly involved in protecting against injury or disease-carrying microorganisms, they do contribute to the body's overall health by ensuring that tissues receive the oxygen they need to function properly. Additionally, red blood cells are not primarily involved in blood clotting; that process is mediated by platelets and a cascade of clotting factors.

What is the role of oxygen gas (O2) in glycolysis?
The first stage is called glycolysis and does not require oxygen. In this stage, ATP molecules are used to help break down glucose into a substance called pyruvate, a molecule that transports electrons called NADH, two more ATP molecules, and carbon dioxide. ... The final stage is called electron transport phosphorylation.
Final answer:
While glycolysis does not require oxygen, oxygen is critical in the steps that follow. It serves as an 'electron magnet' in the electron transport chain and helps regenerate NAD+ from NADH, thereby enabling the continuation of cellular respiration and the production of a significant amount of ATP.
Explanation:
Glycolysis is an anaerobic process and does not require oxygen to proceed. However, oxygen plays a critical role in the later steps of cellular respiration, where the NADH produced in glycolysis can be oxidized. In the presence of oxygen, this process is efficient and leads to the production of much more ATP than glycolysis alone. The oxygen acts as an 'electron magnet' in the electron transport chain, helping to drive electron flow, which is crucial for ATP synthesis. It also regenerates NAD+ from NADH, which is essential for both glycolysis and the citric acid cycle to continue.

Damian grew a plant from a leaf cutting. How did the plant reproduce?
A.
binary fission
B.
budding
C.
sexually
D.
vegetative propagation
Final answer:
Damian's plant reproduced through vegetative propagation, an asexual reproduction method that allows a new plant to grow from a fragment of the parent plant, ensuring that it is genetically identical to the parent.
Explanation:
Damian grew a plant from a leaf cutting. This method of reproduction is known as vegetative propagation, which is a form of asexual reproduction. In this process, a new plant grows from a fragment of the parent plant, such as a leaf, stem, or root, without the involvement of sexual reproduction. The new plant is genetically identical to the parent plant, and this can be a natural or artificial method. Examples of natural vegetative propagation include the growth of plants like ginger, sweet potato, and kalanchoe, which can reproduce from parts such as buds on the stem or leaves. In contrast, artificial vegetative propagation includes methods like cutting, grafting, and layering, often used by gardeners and horticulturists to propagate plants.

Explain how phosphorus runoff into oceans and lakes from farming has a negative impact on the ecosystem.
Phosphorus runoff from farming practices into water bodies such as oceans and lakes can result in harmful eutrophication. This excess nutrient can encourage the rapid growth of algae which, when they decompose, deprive the water of oxygen. This can be harmful or lethal to aquatic species, disrupting the ecosystem.
Explanation:Phosphorus runoff from farming practices can negatively affect the ecosystem of bodies of water, such as oceans and lakes. When excessive phosphorus enters these water bodies, it can cause a process known as eutrophication. Eutrophication refers to the enrichment of a water body with nutrients, which encourages the rapid growth of algae, also called algal blooms. As these algal blooms die off, they are decomposed by microorganisms that use up oxygen in the water. This depletion of oxygen can be harmful, if not deadly, to fish and other aquatic species and therefore disrupts the balance of the ecosystem.

What does it mean when a compound chemical formula does not include any numbers
it means you have one atom of each element in the formula
Answer:
When a compound chemical formula does not include any number it means that compound has only one atom of the elements the compound is made up of.
For example, HCN is a compound made up of one atom of hydrogen, carbon, and nitrogen so it does not contain any number in its chemical formula.
The number present in front of any chemical formula of a compound signifies that there are that many molecules of the element is present in the compound. For example, 3O₂ contains 3 molecules of oxygen not 3 atoms of oxygen.
