how do the locations where photosynthesis occurs differ in prokaryotes and eukaryotes

Answers

Photosynthesis takes place on the folds in prokaryotes and in specialised organelles in eukaryotes. Prokaryotic cells don't have specific organelles or a remote nucleus.

What is photosynthesis?

Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidised, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell. Water is converted into oxygen and carbon dioxide into glucose as a result. After storing energy within the glucose molecules, the plant releases the oxygen back into the atmosphere.

Chloroplasts, which are tiny organelles found inside plant cells, are there to store solar energy. Chlorophyll, a light-absorbing pigment found in the thylakoid membranes of the chloroplast, is what gives plants their green hue.

Hormone: Exocrine: Endocrine: Humoral stimuli: Neural stimuli: Hormonal stimuli: Permissiveness: Synergism: Antagonism:

Answers

Hormones are released by endocrine glands by three mechanisms including humoral stimuli, neural stimuli, and hormonal stimuli.

Humoral stimuli, hormonal stimuli, and neurological stimuli are the three main ways that endocrine glands are triggered to produce and release hormones. A change in extracellular fluids like blood or the ion content in the blood that impacts the release of hormones is known as a humoral stimulus. A hormone is released in reaction to a hormonal stimulus, which is the release of another hormone. Some endocrine glands release hormones when they are stimulated by hormones produced by other endocrine glands. When the neurological system directly triggers the release of hormones from the endocrine glands, this is referred to as a neural stimulus.

Negative feedback is primarily responsible for controlling hormone release and production. A stimulus causes the release of a substance in negative feedback systems; when the substance reaches a specific level, it sends a signal that prevents further release of the substance. By doing this, a specific range of hormone concentrations in the blood is maintained.

https://brainly.com/question/1884866

#SPJ1

The controlled variable in the experiment "Are fingerprints inherited?" refers to the factors or conditions that are kept constant throughout the experiment. In this case, the controlled variables could include:

1. Age and gender of the participants: To ensure consistency and eliminate any potential influences, it is important to control for the age and gender of the individuals participating in the experiment. Fingerprint patterns may change with age, so controlling for this factor helps isolate the inheritance aspect.

2. Environmental conditions: The experiment should be conducted under controlled environmental conditions to minimize any external factors that could affect fingerprint patterns. This includes temperature, humidity, and any other factors that could potentially alter the fingerprints.

3. Method of fingerprint collection: The technique used to collect fingerprints should be consistent for all participants. It should be standardized and applied uniformly to ensure accurate comparison and analysis of the fingerprints.

4. Analysis method: The method used to analyze the fingerprints should also be consistent across all participants. This includes the tools or software used, the criteria for categorizing and comparing fingerprints, and the overall approach to data analysis.

By controlling these variables, researchers can focus on studying the specific aspect of inheritance in fingerprints, without the interference of other potential factors.

Which contains more potential energy, a large, complex molecule like a protein, or the smaller amino acid subunits of which it is composed

Answers

A large, complex molecule such as a protein contains more potential energy than the smaller amino acid subunits of which it is composed. This is because a protein is a polymer, meaning it is composed of multiple molecules linked together in specific ways.

When these molecules are linked together, the bonds between them store energy. This energy is refers to potential energy. When compared to the smaller amino acid subunits, the potential energy stored in the protein is much greater. This is due to the fact that the potential energy stored in a protein is the sum of the potential energy of all the individual amino acids.

Additionally, the bonds that join the amino acids together in a protein are much stronger than the bonds that link the amino acids in the smaller subunits. Therefore, proteins contain more potential energy than the smaller amino acid subunits of which they are composed.

How does an increase in cell size affect ratio of surface area?

Answers

As the cell radius increases, the surface area increases as the radius squared, but the volume increases as the radius cubed (much faster). Therefore, as the cell size increases, the surface area to volume ratio decreases.

Cell proliferation reduces the surface area to volume ratio. This is because as a cell grows, its volume (its internal contents) increases faster than its surface area (its cell membrane).

As cells grow larger, the surface area to volume ratio decreases dramatically, similar to an agar cube. Larger cells have to transport substances across membranes, but they deliver a larger volume and a proportionately smaller surface area.

C. nitrogen oxides.
D. particulate matter.
E. VOCs

Answers

Particulate Matter (PM) is the air pollutant least successfully removed from the air by technologies in developed nations.

Particulate matter is a mixture of solid particles and liquid droplets found in the air. Particulate matter is made up of liquid droplets, dust, dirt, soot, and smoke.

Particulate matter can be inhaled and can cause serious health problems, including respiratory and cardiovascular disease. PM is generated by a variety of sources including combustion, construction, and natural sources such as dust storms.

While many technologies have been developed to reduce PM emissions, they are not always effective in removing PM from the air, especially in heavily industrialized areas due to several factors.

One major reason is that particulate matter can come from a wide variety of sources, such as industrial emissions, transportation, agriculture, and natural sources such as dust storms and wildfires. This makes it difficult to target and effectively reduce the sources of particulate matter.

Another reason is that particulate matter can be transported over long distances by winds, making it difficult to contain and control. This means that even if local sources of particulate matter are reduced, it can still be a problem due to pollution from other areas.

Additionally, particulate matter is very small and can be hard to filter out of the air. The cost and technology required for filtration systems, like HEPA filters or electrostatic precipitators, can be expensive and challenging to implement, especially in developing countries.

In conclusion, particulate matter is a challenging air pollutant to remove, due to its various sources, its transportability, and the difficulty of filtration. A multi-pronged approach including reducing the sources, controlling emissions, and using advanced filtration systems is needed to effectively reduce particulate matter in the air.
