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

Answer:

Fireflies emit light. The production of light by an organism is called bioluminescence. To generate visible light, cells in a firefly's tail produce thousands of luciferase enzymes. Luciferase binds to a chemical called luciferin. Once bound, the luciferase enzyme speeds up a chemical reaction that combines an oxygen molecule and luciferin to produce oxyluciferin. This reaction requires energy and releases light. Which of the following best describes how the luciferase enzyme speeds up the chemical reaction?

Explanation:

b

The description that best describes how the luciferase enzyme speeds up the chemical reaction is - Luciferase decreases the amount of energy required for the reaction to start.

Fireflies generate a chemical reaction that allows their body to emit light, inside their body. This light generation is called bioluminescence. This process involves various steps:

Thus, the correct answer is - Luciferase decreases the amount of energy required for the reaction to start.

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.

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.

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.

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.

effererent neurons signal muscles to contract

Muscles can contract because they are made of efferent neurons.

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.

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.

Answer:

The mass of hydrogen peroxide, H2O2 would be calculated like this: H2O2 has 2 hydrogen atoms and 2 oxygen atoms in it. So one molecule of hydrogen peroxide weighs in at 34.02 u.
