when abscisic acid triggers stomata to close what has happened to the turgor pressure

Answers

Answer 1
When the soil water is in not sufficient to keep up with demands of transpiration (A process where plants lose water), the stomata closes. The opening and closing of the stomata is controlled by the guard cells. And because tugor is lost (less osmosis) This process is often called pasmolysis i.e the process where plants lose water in a hypertonic solution.

Answers

Student 2 has seen the most bio-diversity.
This is because all the others see animals of the same species.

As for the other parts of your question, I don't think I can help too much with that.

Answer:

Please see below

Explanation:

If we define biodiversity as the number of species in an ecosystem (without considering abundance) then student 2 got the area with the greatest biodiversity, because he observed three species, when all other students observed only one species.

Think globally, act locally! is an expression that calls for action, and its foundation is that even a small local action can, when joined with other small local actions, result in a larger impact with a global impact.  A great idea isn't it? It basically empowers you to act with a notion that it will matter.

If we consider the case for carbon, many organisms are part of its biochemical cycle, like plants, herbivores and carnivores, and even detritivores. The plants use carbon dioxide from the atmosphere to buid their tissues which are later consumed by herbivores that are then eaten by the carnivores. In each of these steps carbon is transferred (recycled) from one link of the food chain to the next. When the plants and the animals die the detritivores decompose them and carbon is incorporated to the soil. During respiration, animals release carbon dioxide back to the atmosphere.

Humans have impacted the carbon cycle by extracting carbon products from the ground (fossil fuels like charcoal and oil) and when they are burnt they are released to the atmosphere enriching the carbon dioxide concentration and causing the greenhouse effect and climate warming.

To reduce the harmful human impact on the ecosystem we could use public transportation instead of driving cars, and use cleaner forms of energy like solar energy.

how are limestone and shells connected to the carbon cycle plz answer and fast

Answers

Final answer:

Limestone and shells are connected to the carbon cycle through the process of carbon sequestration. Marine organisms extract calcium carbonate from the water to build their shells, which eventually accumulate on the ocean floor and form limestone deposits. This process helps to remove and store carbon from the atmosphere.

Explanation:

Limestone and shells are connected to the carbon cycle through the process of carbon sequestration. When carbon dioxide  dissolves in water, it reacts with water molecules to form calcium carbonate, which is a major component of limestone and shells. Marine organisms, such as clams and corals, extract calcium carbonate from the water to build their shells. Over time, these shells accumulate on the ocean floor and form limestone deposits. This process helps to remove and store carbon from the atmosphere, contributing to the carbon cycle.

which function function for prokaryotes is described by binary fission?

Answers

answer is reproduction

Answer:

Binary fission or bipartition is a way of asexual reproduction

Explanation:

Most bacteria depend on binary fission to spread. Conceptually, this process is simple; The cell simply needs to grow twice its size and then divides into two. But, in order to remain viable and competitive, the bacteria have to divide at their own time, in their own place, and they must provide each stem. The cell division of the bacteria is studied in many parts of the world. This research is revealing the genetic mechanisms that direct and regulate bacterial cell division. Understanding the mechanisms of these processes is of great interest because this allows the development of chemical products and new antibiotics aimed at interfering with the cell division of bacteria.

Before binary fission occurs, the cell must copy its genetic material (DNA) and deposit it at the ends of the cell, likewise copying the different types of proteins that the new cell division machinery will include.

Which enzyme is responsible for unzipping the dna double helix?

Answers

The enzyme that untwists and unzips the double helix of DNA at the replication forks is called helicase, A protein that functions in DNA replication, helping to relieve strain in the double helix ahead of the replication fork.

The enzyme responsible for unzipping the DNA double helix is DNA helicase.

What is DNA?It stands for deoxyribonucleic acid and is a genetic material.It is a long chain of polynucleotide.Each nucleotide consists of: deoxyribose sugar (carbon-containing compound), phosphate group and nitrogenous bases (nitrogen-containing compound).Nitrogenous bases is of two types: Purines (consisting Adenine and Guanine) and Pyrimidine (consisting Cytosine and Thymine).It is a double helical structure in which Adenine pairs with Thymine by forming two hydrogen bonds whereas Guanine pairs with Cytosine by forming three hydrogen bonds.In order to start replication this DNA helix should be unwind. This is done with the help of enzyme DNA helicase.What is DNA helicase?"It is a class of enzymes that catalyze the separation of duplex nucleic acids into single strands in an ATP-dependent reaction."

Which structure allows upper respiratory infections to spread from the throat to the tympanic cavity?

Answers

The Eustachian tube is the structure that allows upper respiratory infections to spread. The eustachian tube is a canal that links the middle ear to the nasopharynx, which is composed of the upper throat and the back of the nasal cavity. It also controls the pressure inside the middle ear, making it equal with the air pressure outside the body.

Final answer:

The Eustachian tube is the structure that links the throat to the tympanic cavity, enabling infection spread. An upper respiratory infection can result in microbes traveling from the nasopharynx through the Eustachian tube to the middle ear, creating an ear infection.

Explanation:

The structure that allows upper respiratory infections to spread from the throat to the tympanic cavity (middle ear) is the Eustachian tube. This tube connects the nasopharynx to the middle ear. When a person has an upper respiratory infection, the microbes can travel through the Eustachian tube, and potentially lead to an ear infection, also known as acute otitis media. This is especially common in children due to the anatomical differences in their Eustachian tubes, which are shorter and have a shallower angle compared to those of adults.

The sequence of anatomical structures through which microbes would pass from the nares (nostrils) to the larynx are as follows: nares, nasal cavity, nasopharynx, oropharynx, and finally the larynx. Additionally, fluid and pathogens can accumulate in the middle ear, leading to increased pressure and infection due to the connection with the nasopharynx via the Eustachian tube.

How does heat transferred through radiation different from conduction and convection /7622668/12287573?utm_source=registration

Answers

Conduction means the flow of heat between two objects that are in thermal contact.There is no actual mass transfer,only the thermal energy is passed from layer to layer.
Convection means transfer of heat between fluids by actual mass transfer. It occurs only in fluids.
Radiation means the emission of thermal energy in the form of electromagnetic waves by an object.

The three different ways of heat transfer include radiation, conduction, and convection of heat energy.

What are the processes of heat transfer?

There are three ways in which heat is transferred into and through the atmosphere including radiation, conduction, and convection.

Radiation is energy which comes from a source and travels through the space at the speed of light. This energy has an electric field and a magnetic field which are associated with it, and has wave-like properties.

Conduction is the process through which heat energy is transmitted through collisions of particles between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are more closer together than in that of gases, where particles are further apart from each other.

Convection is the process of heat transfer through the bulk movement of molecules within fluids such as gases and liquid molecules. The initial heat transfer between the objects and the fluids takes place through conduction, however the bulk heat transfer happens due to the motion of fluid.

What would you perceive if the optic nerve were mechanically stimulated?

Answers

Stimulating the optic nerve might cause flashes of light to appear in one's vision. This would happen due to an on/off stimulation of the neurons that would cause, at times, full light stimulation, and at other times, no stimulation.
Final answer:

If the optic nerve is mechanically stimulated, it may produce perceived sensations of light called phosphenes, although there would likely not be regular imagery like that produced by normal light stimulation. Additionally, mechanical stimulation doesn't typically affect pupillary responses.

Explanation:

If the optic nerve were mechanically stimulated, you would likely perceive some form of visual sensation. This is due to the nature of the optic nerve, which sends signals from your retina to your brain. These signals are usually instigated by light hitting photoreceptor cells in the retina, but mechanical stimulation could potentially cause a similar effect.

However, mechanical stimulation likely will not produce regular images as typically formed by the eye. Instead, it may produce what are known as phosphenes - perceived sensations of light caused by stimulation of the visual system other than by light itself. For example, applying pressure to the eyeball can mechanically stimulate the optic nerve and cause the perception of light flashes.

In connection to the provided reference, this process is not to be confused with the automatic responses of the pupil - its dilation and constriction in response to light. These responses are coordinated by signals from the optic nerve travelling to the brain, then relayed via the oculomotor nerve (for pupil constriction) and sympathetic pathways (for dilation) to the iris. Mechanical stimulation wouldn't result in this detailed process - rather it would likely cause a simpler, direct response such as the perception of light flashes.

To study cells with a light microscope different types of stains are usually available. why is it generally more useful to stain eukaryotic cells than prokaryotic cells?

Answers

Cells are difficult to see in light microscopy,so to help visualize the structure of cell ,dyes are used to impart a particular color to cells. Eukaryotic cells have both acidic and basic components so, Hematoxylin and Eosin staining is the standard method of staining used for an eukaryotic cell. Hematoxylin is a basic dye that binds to negatively charged DNA and RNA and is blue in colour.Eosin is pink in color and it binds to positively charged particles like the mitochondria and other components of cytoplasm.
