Explain where the enzymes for electron transport are located in bacteria (prokaryotes) if they don't have internal membranes, and therefore do not have a mitochondria
In bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.
Bacteria lack mitochondria, i.e. bacteria have no membrane-bound organelles.
In consequence, bacterial enzymes responsible for the electron transport chain are localized in the plasma membrane.
The electrochemical proton (H+) gradient required to create Adenosine triphosphate (ATP) from ADP and phosphate (Pi) is generated across the plasma bacterial membrane.
In bacteria, the electron transport chain is generally shorter and contains a lower phosphorus-oxygen ratio than the mitochondrial (eukaryotic) electron transport chain.
In conclusion, in bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.

Fossils show how an organism may have lived, what it ate, and where it lived, Transitional fossils may show how one organism had many characteristics of two different organisms, Evidence of both prehistoric and modern features, Changes over time supports the Theory of Evolution by Natural Selection.
what is evolution of species ?evolution can be defined as the process where the genetic changes that occur in a population over successive generations.
here the changes occur on the genetic level of a population and it is being transferred from one generation to another.
Biological evolution takes place as a result of natural selection and its result may be minimal (unnoticeable) or significant (noticeable).
evolution includes microevolution (minor genetic changes within a specie or population) and macroevolution (large evolutionary changes above the species level).

When recommending solutions to decrease human impact, which location were you able to make the greatest positive impact?
What recommendations would you give to your local community to help to decrease the local effects of human impact on the environment? List 2 recommendations and how they will positively impact your community.
What recommendations would you give to the global governments to help decrease the global effects of human impact on the environment? List 2 recommendations and how they will positively impact our planet.
Answer: 1. When creating solutions to reduce the human impact on nature, I believe that it is possible to cause the greatest positive impact in rural areas where agricultural production in the region is concentrated. This is because agriculture is an activity that causes a great impact, but it is necessary that the environment and nature are preserved so that it is possible for griculture to continue being carried out.
2. The first recommendation that I would make to my community is to adopt the use of selective garbage collection. This recommendation would allow any material that could be recycled not to have contact with materials that could prevent recycling. By recycling this material, the amount of waste would be reduced and this would pollute the environment less, in addition to reducing the creation of dumps. The second recommendation I would make would be to ask people to reduce the amount of plastic waste and prefer to use products with paper packaging. This would also increase the amount of recyclable material and promote less plastic pollution that takes a long time to decompose.
3. The first recommendation I would give to local governments is to encourage the use of renewable energy in their territories. The use of this type of energy would decrease the burning of fossil fuels, which would have less impact on our atmosphere. The second recommendation I would make would be to ask governments to create guidelines for the disposal of waste in cities, prohibiting waste from being disposed of in the oceans, as well as sewage. This would allow less pollution of the oceans, keeping natural resources healthy and available.

WILL GIVE BRAINLIEST!!!!! In a paragraph, answer the following questions. 1. What are some ways the body maintains homeostasis? 2. What is the difference between an internal stimuli and an external stimuli? 3. In terms of maintaining homeostasis, why do you think humans vomit?
Answer:
1 Answer
Temperature. The body must maintain a relatively constant temperature. ...
Glucose. The body must regulate glucose levels to stay healthy. ...
Toxins. Toxins in the blood can disrupt the body's homeostasis. ...
Blood Pressure. The body must maintain healthy levels of blood pressure. ...
pH.
2 Answer
An external stimulus is a stimulus that comes from outside an organism and causes a reaction. An internal stimulus is a stimulus that comes from inside an organism. You may have experienced an internal stimulus of hunger after a long day at school, and this prompts you to eat some food in order to regain needed energy.
3 Answer
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

List the three domains used to classify organisms. Then, describe two characteristics of organisms in each domain.
There are three domains:
the ARCHAEA, BACTERIA, and EUCARYA
oragnisms from ARCHAEA and BACTERIA have a prokaryotic cell structure, whereas organisms from the domain EUCARYA encompass cells wirh a nucleus confining the genetic material from the CYTOPLASM.
and all of this is the answer..good luck
The three different domains of organisms are Archaea, bacteria, and Eukarya.
What are different domains of organisms?The three different domains in which organisms are classified are Archaea, Bacteria, and Eukarya. Prokaryotic organisms are the organisms which belong to either of these domains such as Archaea or the domain Bacteria, the organisms with eukaryotic cells belong to domain Eukarya.
Domain Archae is further divided into three phyla namely, Crenarchaeota, Euryarchaeota, Korarchaeota.
Domain bacteria is further classified into 5 phyla of the domain namely Proteobacteria, Cyanobacteria, Eubacteria, Chlamydias, and Spirochaetes.
The domain Eukarya consists of organisms which have eukaryotic cells and is divided into four kingdoms including Protista, Fungi, Plantae, and Animalia.

Nonvascular plants do not have a vascular system, or a series of tubes for transporting materials. Why are nonvascular plants typically smaller than vascular plants?
Answer:
The lack of features, such as a multi-layered epidermis or bark, means that non-vascular plants don't grow very tall and typically remain low to the ground. As such, they don't need a vascular system to transport water and nutrients.
Explanation:
Answer:
Nonvascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances. Another characteristic of nonvascular plants that sets them apart from vascular plants is that they lack roots.

When was Escherichia first isolated and characterized?
When was Escherichia first isolated and characterized?
Answer:
Escherichia was first isolated and characterized in 1985
Explanation:
Think of another science topic you have studied earlier. How does that topic connect to what we have learned about populations and resources? Be creative! Consider how something else you have studied in science might be affected by the resources available. Perhaps you have studied another topic where stability and change is important?
One science topic I have studied earlier is ecology, which studies the relationships between organisms and their environment.
What is ecology?Ecology is closely connected to populations and resources as the availability of resources can impact the growth and survival of populations. For example, the availability of food, water, and shelter can affect the size and distribution of populations, while the use of resources can impact the environment and other species.
Ecology also emphasizes the importance of stability and change in ecosystems, as changes in one population or resource can have cascading effects on other parts of the ecosystem. Overall, the study of ecology provides insights into how populations interact with their environment and the importance of resource management for maintaining healthy ecosystems.
