Most animal cells are surrounded by a cell wall. attached to each other via plasmodesmata. embedded in an extracellular matrix. embedded in a lipid matrix.

The structures or cells bile encounters are in the order: Hepatocyte, Bile canaliculus, Common hepatic duct, Cystic duct, and Gallbladder.

The liver of most vertebrates produces bile, also known as gall, which is a dark-green to the yellowish-brown fluid that aids in the small intestine's breakdown of lipids. Bile is continuously created by the liver in humans (liver bile), and it is stored and concentrated in the gallbladder. Hepatic bile is made up of 200 meq/l inorganic salts, 0.7% bile salts, 0.2% bilirubin, 0.5% lipids (cholesterol, fatty acids, and lecithin), and 97-98% water. Biliverdin, a green oxidized version of bilirubin, is one of the two primary pigments in bile. They combine to give feces their specific brown hue color. Adult humans produce about 400 to 800 milliliters of bile every day.

Answer:

When considering adding mycorrhizal species to the sand of disturbed beaches, to see their effect on grass growth, the independent variable of the study would be the addition of mycorrhizal species to the beach sand.

Explanation:

Mycorrhiza is a symbiosis between fungi species such as Ascomycota, Basidiomycota or Glomeromycota and the roots of a plant, which allows it to take advantage of the inorganic nitrogen and phosphorus found in the soil.

The effect of the symbiosis that rubs the mycorrhiza is to promote the synthesis of nutrients in the plant and improve its growth and development.

In a study in which it is intended to add mycorrhizal fungi to the beach sand to observe the growth of grass, the independent variable of the study will be the addition of mycorrhizae to the sand, while the dependent variable is the growth of grass, the measurable effect.

In this experiment, mycorrhizal fungi is considered independent variable.

In this experiment, mycorrhizal fungi is the independent variable because no effect or impact occurs on it due to changes of sand or beaches in the experiment whereas sand or beaches are considered as dependent variable because the sand or beaches show change when the concentration of mycorrhizal fungi changes.

Independent variable is a type of variable which is not dependent on other factors whereas dependent variable depends on other variables so we can conclude that mycorrhizal fungi is independent variable.

Explanation:

The atomic number consists of only the number of neutrons. Atomic mass also includes the number of protons. Option A.

The atomic number is the number of protons in an atom. On the other hand, the number of neutrons for a particular element can vary. Together, the number of protons and the number of neutrons determine the element's mass number. The main difference between atomic number and mass number is what the atomic number indicates.

Indicates the number of protons present in the atom, and the mass number indicates the total number of protons and the number of neutrons present in the atom. Since atoms are electrically neutral, the number of positively charged protons must equal the number of negatively charged electrons. Since neutrons do not affect the charge, the number of neutrons does not depend on the number of protons and varies even between atoms of the same element.

C - 4-Gene therapy (Recombinant viral DNA is used to treat some diseases like cystic fibrosis)

D - 1-DNA fingerprint (Random DNA sequences that are different from one person to another)

Yes, because the ratio of alleles is not following the Mendelian ratio.

According to Mendelian genetics, if there is a gene F at any locus then the possible phenotypes it can produce will be Ff, ff, and Ff in the ratio of 1:2:1, respectively. Out of all three FF and ff will be homozygous whereas Xx genotype will be heterozygous and if the phenotype of Ff resembles that of FF then it will be confirmed that F is dominant over f.

According to the given condition, the dominant trait (F) is increasing in the population and the recessive one is reducing. Thus, individuals with FF will be highest (60%), followed by Ff (30%). ff proportion in the population is lowest (10%). This makes the ratio as 6:3:1 which proves the evolution of the population with a high percentage of the dominant allele.

Note: The given question is incomplete but your expected question probably be like this, “Expected question: You have collected data on the observed genotype frequencies of the next generation. they are 60% FF, 30% Ff, and 10% ff. Based on these observations and your expectations, is this trait currently evolving in this population? Why or why not?”

Answer:

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.

Explanation:

Asúmase que el balón es rígido. Supongamos que el oxígeno se comporta como un gas ideal, entonces la ecuación de estado es la siguiente:

\(P\cdot V = \frac{m\cdot R_{u}\cdot T}{M}\) (1)

Donde:

\(P\) - Presión, medida en atmósferas.

\(V\) - Volumen, medido en litros.

\(m\) - Masa, medida en kilogramos.

\(M\) - Masa molar, medida en kilogramos por kilomol.

\(T\) - Temperatura, medida en Kelvin.

\(R_{u}\) - Constante de los gases ideales, medida en atmósfera-litros por kilomol-Kelvin.

El aire experimenta un proceso isocórico e isotérmico, entonces obtenemos la siguiente relación:

\(\frac{P_{1}}{m_{1}} = \frac{P_{2}}{m_{2}}\) (2)

Nótese que los subíndices 1 y 2 representan los estados inicial y final de proceso.

Si sabemos que \(P_{1} = 41\,atm\), \(m_{1} = 12\,kg\) y \(P_{2} = 25\,atm\), entonces la masa final del aire es:

\(m_{2} = \frac{P_{2}}{P_{1}} \cdot m_{1}\)

\(m_{2} = \left(\frac{25\,atm}{41\,atm}\right)\cdot (12\,kg)\)

\(m_{2} = 7.317\,kg\)

La masa que se ha extraído del balón es:

\(\Delta m = m_{1}-m_{2}\)

\(\Delta m = 12\,kg-7.317\,kg\)

\(\Delta m = 4.683\,kg\)

Quedan 7.317 kilogramos de oxígeno en el balón y se extraen 4.683 kilogramos de oxígeno en el proceso.

Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell's cytoplasm or embedded within the endoplasmic reticulum.

Answer:

d

Explanation:

The process that results in two identical cells is known as Mitosis. Thus, the correct option for this question is D.

Mitosis may be defined as a type of cell division through which two identical daughter cells are produced from a parental cell. These daughter cells are genetically identical to their parental cells and are mostly diploid in nature.

While the process of meiosis typically produces four daughter cells from a parental cell. These daughter cells are not genetically identical to their parental cells. These cells are haploid in nature.

The process of fertilization may be defined as when two distinctive gametes are fused together in order to produce a zygote. While replication is the duplication or synthesis of genetic material during the S-phase of Interphase.

Therefore, mitosis is the process that results in two identical cells. Thus, the correct option for this question is D.

Answer: the population of frogs and mice would increase which would cause the population of grasshoppers to decrease

Explanation: I’m on the test right now and I’m looking at the web, the mice and frog get eaten by the snake, and the grasshopper get eaten by the frog and the mice, so if the mice and frog population increases the populating of the grasshopper would decrease :)

If snakes were removed from the food web, the population of frogs and mice would increase which would cause the population of grasshoppers to decrease.

Snakes predate on frogs and mice. Thus, if they are removed from the food chain, the population of frogs and mice would be less pressured and, therefore, thrive.

With the thriving population of frogs and mice comes the pressure on the population of grasshoppers. Frogs and some species of mice feed on grasshoppers.

Thus, if the population of frogs and mice thrives as a result of the absence of snakes, more grasshoppers will be eaten and the population of grasshoppers will decrease as a result.

he dendrotoxins produced by the mamba snakes (Dendroaspis) affect the repolarization phase of the action potential. Dendrotoxins are peptides that are isolated from the venom of mamba snakes. These toxins are potent blockers of voltage-gated potassium channels.

Voltage-gated potassium channels are responsible for the repolarization phase of the action potential. They allow the flow of potassium ions out of the cell, thereby returning the membrane potential to its resting state. In the presence of dendrotoxins, the potassium channels are blocked, and the flow of potassium ions is reduced.

This causes the repolarization phase to be delayed or prevented altogether, leading to prolonged depolarization and a prolonged action potential. This can result in a variety of symptoms, including muscle paralysis, respiratory failure, and even death.

The p53 gene is an example of a tumor suppressor gene.

Tumor suppressor genes are responsible for regulating the cell cycle and preventing the development of cancer by either repairing DNA damage or inducing cell death. The p53 protein is phosphorylated in response to DNA damage, which stabilizes it and allows it to accumulate in the nuclei of cells. Once in the nucleus, phosphorylated p53 functions to block the cell cycle and activate DNA repair mechanisms, preventing the accumulation of mutations that can lead to cancer. Mutations in the p53 gene are associated with many different types of cancer, as well as other genetic disorders. Understanding the role of phosphorylated p53 in DNA damage response is important for developing new treatments for cancer and other diseases that involve DNA damage.
