1) The proper taxonomic groups are most times always defined by the traits,these traits are the ones that are shared among members of the group eventhough they aren't found in species that are closely related.
2) The two traits are all common as they arise in the ancestors of all the hominins, however,they are not found in the nonhominins apes
3) The evolution of these hominins involved several changes that are different and that happened at different times,and only two of these features,out of all that we have evolved early enough to actually apply to all the hominins.

A student is asked to build a model of an atom with 6 protons and 6 electrons. The student is then asked to make an identical model of the same atom but make it an
ion. To be successful in this project, the student will:
Put the electrons in the middle of the model and distribute the electrons around the protons. The ion will have seven protons.
Put six protons in the center of the atom and distribute the electrons around the protons. The ion will look the same but have seven or five electrons.
Put six protons in the center of the model, and six electrons around the outside, then add one electron or take away one electron to make an ion.
Place electrons and protons in the center of the atom and create an ion by adding one more proton and one more electron to the center of the atom.

List three activities of a cell that help it live
Answer:
1. The use of ATP, also known as the enegy currency of the cell. Cellular functions need ATP to survive.
2. Cell division. Cells need to reproduce for repairing tisues, healing, and more.
3. Active and passive transport. This is important to control what gets in and out of the cell. The selectively permeable membrane is responsible for this process.
Hope this helps! :)
Metabolism, respiration, and reproduction are essential activities that help a cell to live and carry out its functions.
What help cells live?Cells have several mechanisms that help them live and carry out their functions. Metabolism, which involves the chemical reactions that occur within a cell, provides the energy and raw materials necessary for life processes. Respiration, the process of converting glucose and oxygen into ATP, also provides energy for the cell.
Cells also have various organelles, such as mitochondria, lysosomes, and ribosomes, that perform specific functions, including energy production, waste removal, and protein synthesis. Additionally, cells have the ability to respond to their environment, adapt to changing conditions, and reproduce to maintain their population.
Furthermore, the genetic material in cells provides instructions for all cellular processes and plays a critical role in the development and maintenance of an organism. In summary, cells have several mechanisms and processes that help them live, function, and contribute to the overall health and survival of the organism.

Giant kelp causing huge ocean forests
Water mold causing destruction of crops
Answer:
Giant kelp causing huge ocean forests
Explanation:
Even though they look like very tall ocean grass that covers the floor and looks stunning it is actually not a plant. It is instead a brown alga and is part of the huge kingdom of life known as Protista. Even though most protozoa are single-celled giant kelp is not. It is a large and complex organism and is the largest protist in the world that we know of.

To explain the decrease in mass of the dark-grown plants, identify the overall chemical reaction that is occuring in the plant cells and connect it to the cellular process underlying the decrease in mass.
Answer:
The correct answer is - cellular respiration.
Explanation:
In the provided data the decrease in the dry mass of the plant occurs due to cellular respiration which is performed in absence of light or plants kept in dark places that did not allow the plant to perform photosynthesis.
Even though there is no production of glucose still need to perform cellular respiration for the energy required to perform cellular functions. This causes the mass of the plants kept in dark is reducing.
Cellular Respiration is defined as the metabolic pathway, which breakdowns glucose to yield ATP. The correct answer is cellular respiration.
The data given indicates the decrease in the dry mass of the plant. It is due to the cellular respiration that is performed in the absence of light. The plants are kept in dark to avoid photosynthesis. Photosynthesis is the process through which plants prepare their food and get energy. Plants store the excess energy in the form of starch.
Although, the plants require energy to survive. The following points can explain the decrease in mass of the plant:
The plants require energy to live and survive, which is provided by cellular respiration. The absence of photosynthesis will lead to no formation of sugars. Thus, the stored energy will be utilized to obtain energy.Therefore, the mass of the plants is kept reducing due to cellular respiration and lack of photosynthesis.

Just like land animals marine fish breathe oxygen. they do so by directing a flow of ocean water over their gills. what can you conclude from this information?
Answer:
They can breathe in oxygen.
Explanation:
By letting it flow over there gills it helps them make oxygen.
Conclusion from this information is:-
Like land animals Marine animals also need oxygen to breathe.For this purpose they have a specialized organ called gills.They direct the flow of ocean water over gills and take oxygen from itWhat are Gills?
is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide.
How gills extract oxygen from water?
Gills contain many filaments, each with thousands of tiny folds called lamellae, which greatly increase the surface area that comes into contact with water. Dissolved oxygen in seawater passes through thin membranes in the lamellae and enters the fish's blood, and carbon dioxide is eliminated.To know more about gills here
