Explanation:
O-16 and O-18 are isotopes as they have the same element (oxygen) but different atomic mass (16 and 18).
The symbol represents the atoms that are isotopes are O-16 and O-18, the correct option is b.
What are isotopes?Isotopes are members of an element family that have the same number of protons but have different numbers of neutrons.
The atomic number of an element on the Periodic Table is determined by the number of protons in its nucleus. Carbon, for example, has six protons and is atomic number 6.
The mass of an isotope, which is the total number of protons and neutrons, is used to identify it. Isotopes are typically written in one of two ways.
The most common illustration are hydrogen as well as carbon isotopes. When it relates to the element Hydrogen, it has three stable isotopes: protium, deuterium, and tritium.
These isotopes share the same number of protons but differ in neutron count, with protium having zero, deuterium having one, and tritium having two.
Thus, the correct option is b.

During Arjun's infection, S. pyogenes was growing in two very different environments-on the surface of his skin and in the deeper tissue. Explain the metabolic pathways S. pyogenes would use in each of these environments and why.
Answer:
Use Phosphotransferase system where glucose is not available.
Explanation:
Streptococcus pyogenes uses its phosphotransferase system for the uptake and metabolism of non-glucose carbohydrate sources in the environment where glucose is not available. Streptococcus pyogenes also uses malate which is a dicarboxylic organic acid that is present in large amount in both tissue and in the external environment. This malate is a non-glucose carbohydrate source used by Streptococcus pyogenes for the production of energy.

Why is it necessary to have a balanced environment ?
Survival of all organisms is actualized due to ecological balance. Various species survive because favorable ecosystems were created. Favorable ecosystem ensures that each organism thrive and multiply as expected. They get enough food to keep them alive. Ecological balance is also important because it leads to the continuous existence of the organisms

Answer:
A) Dark moths had a survival advantage in rural Birmingham.
Explanation:
In the given graph, the data about dark moths are colored orange, and the data about light moths are colored green. We can clearly see this in the image I've attached below.
We can see that the percentage of recovered dark moths is greater in Dorset, while the percentage of recovered light moths is greater in Birmingham. This means that the dark moths had a survival advantage in Dorset, while the light moths had the advantage in Birmingham. This is why statement A is not supported by Kettlewell's data.

Teresa did a trick in which she placed dishes on a tablecloth placed on a card table. She pulled quickly on the tablecloth, and it came off the table, leaving the dishes behind on the table. Teresa’s friend tried the same trick and ended up with a pile of broken dishes on the floor. Teresa told her that she didn’t pull the cloth fast enough. She also said that her friend might have better results with heavier dishes. Using Newton’s laws, explain why these were good suggestions.
Answer:
the speed of the cloth being pulled left no time for the dishes to move. heavier dishes have a harder time moving because of the gravitational pull. In the second law, the force on an object is equal to its mass times its acceleration. if the dishes had no acceleration they will not move.
Explanation:
The plates couldn't move because of how quickly the cloth was being dragged. According to the second law, an object's force is determined by multiplying its mass by its acceleration. The dishes won't move if there was no acceleration.
What is newton's second law of motion?When there are unbalanced forces acting on an object, Newton's second law of motion applies. According to the second law, the mass of the item and the net force acting on it both affect how quickly an object accelerates.
An object's acceleration is directly proportional to the net force applied on it and inversely proportional to its mass. An object's acceleration increases as the amount of force exerted on it does.
A decreasing acceleration is caused by a rise in an object's mass.
Therefore, The plates couldn't move because of how quickly the cloth was being dragged. According to the second law, an object's force is determined by multiplying its mass by its acceleration. The dishes won't move if there was no acceleration.

Example of form follows function in cell biology
Answer:
Example: human's arm and bat's wing share the same evolutionary origin and exhibit similar internal anatomical structures, but they have different forms because these structures have different functions
Explanation:
The idea "Form Follows Function" indicates that the form/shape of a structure is directly associated with the function of that structure. The relation form-function is a consequence of the evolutionary process. Thus, in different species, analogous structures that share the same evolutionary origin can have different forms and/or shapes because they perform distinct functions, such as in the example above.

2. What are individual characteristics? Give an example of an individual characteristic?
Answer:
What are individual characteristics? Give an example of an individual characteristic. Individual Characteristics are properties or physical evidence that can be attached to a common source, any examples could be something such as Nuclear DNA, tool marks, and fingerprints.
What are class characteristics and how are they different from an individual characteristic? Class characteristics are not unique to a particular object but place the particular bit of evidence into a group of objects. Individual characteristics narrow down the evidence to a single, individual source. The type of handgun with which a victim is shot is a class characteristic.
What are physical and chemical properties? Give an example of each. A physical property is an aspect of matter that can be seen or measured without changing its chemical composition. Examples of physical properties include color, molecular weight, and volume. A chemical property is observed only by changing the chemical identity of a substance. In other words, the only way to detect a chemical is to perform a chemical reaction. Examples of chemical properties are reactivity, flammability, and oxidation state.
What do forensic scientists do to collect and preserve soil samples? The combination of materials in soil may link a suspect to the crime scene if the soil is transferred to the suspects shoes or clothing. Forensic scientists compare soil samples to see if there is a match that links the suspect to the crime.
Explanation:
Individual characteristics are unique traits or attributes that distinguish one person from another.
These qualities are specific to an individual and may be influenced by genetics, environment, experiences, or personal choices.
Individual characteristics encompass a wide range of aspects, including physical features, personality traits, skills, interests, and preferences.
For instance, physical features such as eye color, height, or facial structure are individual characteristics that are genetically determined.
Personality traits like extroversion, empathy, or creativity are also individual characteristics shaped by a combination of genetic and environmental factors.
These characteristics contribute to the diversity and complexity of each person, making every individual special and different from others.

Two true-breeding stocks of pea plants are crossed. One parent has red, axial flowers and the other has white, terminal flowers; all F1 individuals have red, axial flowers. The genes for flower color and location assort independently. If 500 F2 offspring resulted from the cross, approximately how many of them would you expect to have red, terminal flowers
Answer:
94.
Explanation:
If 500 F2 offspring resulted from the cross, approximately 94 plants out of 500 plants have red, terminal flowers. The offspring produced in F2 generation in the ratio of 9:3:3:1. According to this ratio, 281 plants having red axial flowers, 94 plants have red terminal flowers, 94 plants have white axial flowers and 31 plants having white terminal flowers. So by totaling 500 plants are received.
