The equation of the photosynthesis is;

6CO2 + 6H2O → C6H12O6 + 6O2.

Photosynthesis is the process by which green plants and some other organisms convert light energy into chemical energy in the form of glucose (sugar). This process occurs in chloroplasts, specialized structures found in the leaves of green plants, and involves the absorption of light by pigments such as chlorophyll.

The energy from light is used to convert carbon dioxide (CO2) and water (H2O) into glucose and oxygen (O2), which is released into the air. Photosynthesis is an essential biological process that provides the basis for almost all life on earth and helps regulate the planet's atmosphere and climate.

Answer: The distribution of skin temperature throughout the body is not uniform (i.e. lower in the extremities than in the trunk) and it also changes with environmental temperature (i.e. it is higher in summer than in winter).

Explanation: The human body regulates body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different. The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F).

0% of their descendants proportion of the children of a cross between aa x aa would be expected not to taste ptc

A single gene with two alleles—the dominant allele "A" and the recessive allele "a"—determines the capacity to taste PTC. A person can taste PTC if they have two copies of the dominant allele "AA." A person cannot taste PTC if they carry two copies of the recessive gene "aa." A person may taste PTC if they possess one copy of each "Aa" allele.

When two heterozygotes "Aa" are bred, half of the progeny will have the dominant gene "A" and the other half will carry the recessive allele "a". Therefore, it is projected that 0% of their descendants would not taste PTC.

Centrioles - Centrioles are self-replicating organelles made up of nine bundles of microtubules and are found only in animal cells.

Explanation:

Please mark me Brainliest!

Centrioles are a unique and important structure found in animal cells. They play a critical role in cell division and help to ensure the proper distribution of chromosomes, which is essential for the growth and development of organisms. Additionally, centrioles are involved in the formation of cilia and flagella, which are important for movement and sensory functions.

Animal cells are one of the two major types of eukaryotic cells, the other being plant cells. Unlike plant cells, animal cells lack a rigid cell wall and chloroplasts. However, animal cells possess unique structures that are crucial for their functions.

One of the unique structures found in animal cells is the centriole. Centrioles are cylindrical structures that are found in pairs near the nucleus of the cell. They are composed of microtubules, which are protein fibers that help to provide structural support and facilitate cell division. The main function of centrioles is to help organize the microtubules during cell division, which is essential for the proper distribution of chromosomes into the daughter cells.

During cell division, the centrioles form the spindle fibers that pull the chromosomes apart and help to ensure that each daughter cell receives an equal number of chromosomes. This is a critical process, as any errors in chromosome distribution can result in genetic abnormalities that may cause diseases such as cancer. Additionally, centrioles are involved in the formation of cilia and flagella, which are hair-like projections on the cell surface that help with movement and sensory functions.

With this information, we can calculate the Nernst potential for potassium at various extracellular potassium concentrations: are E = -0.077 V, -0.051 V, -0.037 V and -0.025 V respectively.

Given that the normal concentration of potassium ions inside a muscle cell is 155 mM, we can use the Nernst equation to calculate the Nernst potential for potassium when the extracellular potassium concentration changes from the normal value.

The Nernst equation is:

[tex]E = ((RT)/(zF)) * ln([K+]out/[K+]in)[/tex]

where:

E is the Nernst potential in volts (V)

R is the gas constant (8.314 J/mol*K)

T is the temperature in Kelvin (K) (assumed to be 298 K)

z is the charge on the ion species (for K+, z = +1)

F is the Faraday constant (96,485 C/mol)

[K+]out and [K+]in are the concentrations of potassium ions outside and inside the cell, respectively.

With this information, we can calculate the Nernst potential for potassium at various extracellular potassium concentrations:

[tex][K+]out = 0.1 mM, [K+]in = 155 mME = ((RT)/(zF)) × ln(0.1/155)E = -0.077 V[K+]out = 10 mM, [K+]in = 155 mME = ((RT)/(zF)) × ln(10/155)E = -0.051 V[K+]out = 20 mM, [K+]in = 155 mME = ((RT)/(zF)) × ln(20/155)E = -0.037 V[K+]out = 40 mM, [K+]in = 155 mME = ((RT)/(zF)) × ln (40/155)[/tex]

E = -0.025 V

We can plot these values of the Nernst potential against the extracellular potassium concentration on a graph with the logarithmic scale on the x-axis. The slope of this curve is negative and represents the ion permeability of the membrane to potassium ions, which is directly proportional to the Nernst potential.

Overall, while animals and fungi have many differences in their physical and biological characteristics, they do share some fundamental similarities, including their evolutionary origins from protists, their absorptive mode of nutrition, and their ability to secrete digestive enzymes.

Animals and fungi are two distinct kingdoms of living organisms. However, they do share some similarities in their characteristics. One such similarity is that both animals and fungi evolved from protists, which are single-celled organisms.

Another shared characteristic between animals and fungi is their mode of nutrition. Both groups use absorptive nutrition, which means they obtain nutrients by absorbing dissolved organic matter from their environment. This is in contrast to plants, which use photosynthesis to produce their own food.

Furthermore, both animals and fungi are known to secrete digestive enzymes. These enzymes break down complex organic molecules into smaller, simpler compounds that can be absorbed and used for energy.

In animals, digestive enzymes are typically produced by specialized organs such as the stomach and pancreas, whereas in fungi, they are secreted externally and then absorbed back into the organism.

Peak action potential depolarization is less than the Na+ equilibrium potential because the depolarization is limited by the balance between the influx of Na+ ions and the efflux of K+ ions.

During an action potential, the opening of voltage-gated Na+ channels leads to an influx of Na+ ions into the cell, which causes the membrane potential to become more positive. However, this depolarization is not enough to reach the Na+ equilibrium potential of +66 mV, which represents the potential at which the driving force for Na+ influx and efflux are equal.

The actual peak depolarization of an action potential is determined by a balance between the influx of Na+ ions and the efflux of positively charged ions, such as potassium (K+) ions, through other ion channels. The K+ channels help to limit the depolarization and prevent the membrane potential from reaching the Na+ equilibrium potential. Additionally, the opening of voltage-gated K+ channels contributes to repolarization of the membrane, which helps to reset the membrane potential and return it to its resting state.
