Explanation:
so e.coli have mitochondria and undergo cellular respiration?
Answer:
No
Explanation:
E. coli are prokaryotes, meaning they do not have membrane-bound organelles like mitochondria.
However, they do perform respiration to produce the energy needed for cellular processes. They can perform both aerobic respiration (in the presence of oxygen) and anaerobic respiration (in the absence of oxygen).
Since they don't have any membrane-bound organelles, these processes take place in the cytoplasm
MRSA is Methicillin Resistant Staphylococcus Aureus. Methicillin used to be nicknamed "gorilla-cillin". Which of the following statements is likely true of MRSA INFECTIONS IN HUMANS?
1. Methicillin is not a good antibiotic to use on this type of infection
2. MRSA is a common infection that is treated by methicillin
3. MRSA originally evolved in gorillas as a zoonotic disease
4. Methicillin is a strong antibiotic and MRSA developed resistance to it, making it harder to treat
Answer:
4. Methicillin is a strong antibiotic and MRSA developed resistance to it, making it harder to treat.
Explanation:
MRSA was first discovered in 1961. It's now resistant to methicillin, amoxicillin, penicillin, oxacillin, and other common antibiotics known as cephalosporins.
Answer:
Option 4) Methicillin is a strong antibiotic and MRSA developed resistance to it, making it harder to treat.

The sodium-potassium pump is a specialized type of transport protein found in your cell membranes. The pump's
job is to move potassium ions into the cell in
the direction of low to high concentration. In order for this to happen, the cell uses energy
to operate the pump. This is an important step in the function of our
nerve cells. What type of transport does the sodium-potassium pump use?
A. Diffusion
B. Active Transport,
C. osmosis
D. Passive Transport
Answer:
Active Transport
Explanation:
Active Transport requires energy input

You are studying natural selection in a population of small marine invertebrates called isopods that live on pink corals. In this population, isopod body color is controlled by one gene with alternate alleles A and a. Isopods can be red (AA), pink (Aa), or white (aa); body size is controlled by another gene with alternate alleles B and b, and they can be large (BB or Bb) or small (bb). A new predator arrives on the reef that is extremely good at preying on isopods that are large and stand out against the corals on which they live (i.e., red or white individuals). Over time, which genetic individuals would you predict would become more abundant in the population with each subsequent generation?
Answer:
Aa, bb
Explanation:
Recall that this question calls our attention to the theory of evolution as postulated by Charles Darwin. Species that are well adapted to their environment are more likely to survive, reproduce and pass on these favourable characteristics to their offspring.
In this case, the coral reefs are pink and pink Isopod species with small bodies are likely to escape the predators. Hence the genetic combination Aa(pink body) and bb(small body) are more likely to survive and reproduce.

Which of the following is not a current theory regarding global climate change? a. Global warming will stimulate crop growth. b. Even the moderate projections on global warming will cause devastation. c. Higher levels of carbon dioxide in the atmosphere will have no effect. d. Sea levels will rise as a result of global warming.
Please select the best answer from the choices provided A B C D
Answer:
c
Explanation:just took the test
Flooding has the potential to spread illness and harm infrastructure and ecosystems. Health problems can reduce worker productivity, raise mortality, and have an impact on the availability of food. Thus, option C is correct.
What is impact of global climate change on ecosystem?Droughts that are more frequent and intense, storms, heat waves, rising sea levels, melting glaciers, and warming oceans can all directly harm animals.
Destroy the habitats they rely on for survival, and have a disastrous impact on people's way of life and communities. Dangerous weather events are increasing in frequency or severity as climate change gets worse.
Therefore, Higher levels of carbon dioxide in the atmosphere will have no effect. Food production and human health can be harmed by drought.

Tell me a description of the urea in simple terms.
Answer:
Urea: A nitrogen-containing substance normally cleared from the blood by the kidney into the urine. Diseases that compromise the function of the kidney often lead to increased blood levels of urea, as measured by the blood urea nitrogen (BUN) test.
Which of the following is an example of diffusion?
A water freezing into ice
B sugar dissolving in a glass of water
C rain falling from the sky
D a stone sinking to the bottom of a lake
A sugar cube is gently dissolved in a glass of still water. Diffusion is the process by which water molecules and sugar molecules interact. By swirling the water with a spoon, we can hasten the diffusion. Thus, option B is correct.
What is the diffusion?Due to the motion of the sugar molecules around the water molecules, sugar dissolves in water. Overall, it exhibits a diffusion mechanism as sugar atoms mix with water atoms.
Sugar will dissolve in water when added to it with a stirring motion. Diffusion is to blame for this, as the sugar will flow down a gradient of concentration.
Diffusion data from sugar solutions, or solutions with no polymer present, suggested that a free water behavior should only be anticipated after a bilayer has covered the sugar molecule.
Therefore, sugar dissolving in a glass of water is an example of diffusion.

Why do you think catalase has to work so quickly?
Answer:
Hydrogen peroxide is toxic.
Explanation:
Hydrogen peroxide is a natural product of the reactions in the cell. However, it is toxic to cells and has to be broken down.
Catalase catalyses the breakdown of hydrogen peroxide into water and oxygen. It is found in all living cells and is very important to prevent the build up of hydrogen peroxide. If catalase didn't work quickly, hydrogen peroxide would accumulate in the cell and poison it, causing the cell to die.

What are the types of neuron ?Neurons basic microscopic unit of nervous system which is responsible for carrying information to different parts of the body by using electrical and chemical signals and coordinate all of the necessary functions of life.
It has three parts such as Soma or cell body which receives information and contain the cell’s nucleus, Dendrites a thin filament which carry the information from other neurons to the soma, Axon is a long projection that carries information from the soma and sends it to other cells.
Neurons involve in impulse transmission can be presynaptic neuron which emits the nerve impulse and the postsynaptic neuron receives this impulse.
Neurons can be Sensory neurons which carry the information from the sensory organs like skin, eyes, ears, nose and Motor neurons, Interneurons form a bridge between two neurons.

How do was the carbon cycle most different before 1900s
Answer:
I would probably say that it was most different because of the cars. The first car was released in 1885, but they weren't really popularized in America until the 1920s. So therefore, Earth's atmosphere was much better than it is now.
