O mRNA is made in large quantities in infrequent batches.
O mRNA is made in small quantities in frequent batches.

Answers

Answer 1

Answer:

O mRNA is made in small quantities in infrequent batches.

Explanation:

mRNA is made in small quantities in infrequent batches because the affinity of positive transcription is lower and affinity of negative transcription is higher which is responsible for production of mRNA from DNA molecule. Transcription is a process in which the information that is present in DNA molecule is copied to new mRNA molecule. Positive transcription factor is a promoter which promotes the initiation of transcription in order to enable RNA polymerase while negative transcription  factor is a repressor protein.

Please write down prearation of perment slides of pollen grains by acetolysis method and study of different pollen characters: study of variation pattern in different taxa.

Answers

Answer is given below

Explanation:

Collection and preservation of pollen material: In clean glass pots containing 70% glacial acetic acid, some of the stamens are applied with clean forceps prior to flower synthesis and sometimes protected from diamonds or mature flower buds. Some polyologists recommend 70% ethyl alcohol to preserve feathers in place of glacial acetic acid. In this condition, pollen-filled feathers can be stored indefinitely.  The wings are transferred to a centrifuge tube and rinsed well with distilled water.the wings are crushed with a glass rod and the mixture is filtered through a cheesecloth or sieve. The lower part is recalled in the centrifuge tube.  A freshly prepared acetolysis mixture containing acetic anhydride and concentrated H2SO4 (sulfuric acid) in a ratio of 9: 1 is poured into a centrifuge tube containing the washed pollen. Care must be taken to connect the conceider. H2SO4 by acetic anhydride drop to prevent overheating. The acetolysis solution reacts violently with water. Glacial acetic acid washers are required to replace water with acetic acid, which does not react violently with the acetolysis solution. Although the acetolysis process varies from pathologist to pulmonologist, the following approach seems to be the most appropriate. From the first to the last acetic acid wash, care is taken regardless of the water solution. Only distilled water should be used for washing to prevent contamination.

Uno de los más grandes atributos que tenemos los Mexicanos es nuestra reconocida variedad cultural, lo cual nos da una identidad única en el mundo.

Somo un país con una de las historias más ricas del planeta, ya que somos descendientes de civilizaciones tan antiguas como la Olmeca y la Tolteca, además de los grandes imperios Maya y Azteca, dos grandes culturas de Mesoamérica.

Cada región en los 32 estados del país, es un México diferente. Lo que nos une es esa preciosa bandera tricolor, con nuestro símbolo patrio: un águila devorando una serpiente.

Somos un país donde se encuentran muchos de los sitios arqueológicos más importantes de las civilizaciones antiguas. Por ejemplo, el mundo Maya: Chichen Itza(petrimonio de la Humanidad por parte de la UNESCO), Palenque, Uxmal, Tulum, entre muchos otros. O el sitio arqueológico de Cholula, con la pirámide cuya nase es la más grande del mundo. En Oaxaca está el sitio arequológico de Monte Albán.

Temporal isolation

Explanation:

Temporal isolation, a type of reproductive barrier caused by variations in the timing of mating receptivity, activity, or fertility, prohibits interbreeding between different but closely related species.

What is the temporal barrier in reproductive isolation?

In biology, temporal isolation is a form of reproductive isolation mechanism that prevents members of closely related species from mating and creating hybrid offspring.

Temporal isolation refers to the situation where two or more species reproduce at various periods. For instance, three different types of orchids live in the same rain forest.

This mechanism arises from differences in the timing of crucial reproductive events.

Therefore, Temporal isolation reproductive barrier will most likely be working against that possibility.

When a volcano erupts, tiny particles from which of Earth's spheres are released into the air?
atmosphere
biosphere
geosphere
hydrosphere

Answers

The geosphere :) that’s where the earth’s mantle and crust is which is where the volcanoes are. So, when they erupt pieces of them are released from the level which they came from (aka the geosphere) hope that helps!

When a volcano erupts, tiny particles from the geosphere are released into the air. So, the correct option is C.

What is Volcano?

A volcano is a geological formation on the surface of the Earth that develops as magma and volcanic ash build up. During an eruption, lava, ash, and gas can escape through a crater or vent that is generally shaped like a mountain.

Explosive or non-explosive eruptions can have a large negative impact on the environment, causing ash fall, landslides, and lava flows, among other things. Tiny geosphere-derived particles are discharged into the atmosphere during volcanic eruptions.

All areas of volcanism contain compound volcanoes, but these volcanic structures are most common at plate convergence zones, where one tectonic plate plunges beneath another towards the earth's mantle.

Therefore, the correct option is C.

Why is the communication results circle linked to the circle labeled science and society

Answers

Answer:

Because these circles have three factors that are directly interconnected.

Explanation:

As you know, communication is one of the primary factors for the creation and maintenance of societies. Societies grow and develop with communication as a starting point and a link between people and the actions that a society lives.

Science, in turn, is also directly influential in the creation and development of society, since it is a transforming factor that shapes society through its constant evolution.

As science evolves, society changes and communication must accompany these changes, so that both society and science continue to exist.

For this reason, we can say that the circle of communication results is linked to the circle called science and society, because these factors are directly interconnected.

Answers

Answer:

P2O3 y BaO

Explanation:

The oxides of the main group metals are basic in nature. They form alkaline solutions when dissolved in water. Similarly, the oxides of main group non metals form acidic solutions when dissolved in water.

P2O5 is an oxide of a main group nonmetallic element in group 15. We expect this oxide to be acidic and form acids when dissolved in water as expected from the chemistry of the group.

Also, BaO is an oxide of barium, a group two main group metal. Hence we expect this oxide to be basic in nature and form alkaline solutions.

Water intoxication results from: A. Dilute body fluids B. Osmosis of water from ICF to ECF C. Decrease in water intake D. Decrease in the osmolarity of interstitial fluids E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids

Answers

Answer:

E.  Dilute body fluids and a decrease in the osmolarity of interstitial fluids

Explanation:

When there is excessive water intake into the body, it can lead to water intoxication. It occurs as result of a combination of dilute body fluids and decrease in the osmolarity of interstitial fluids.

When excess water is taken into the body, the extracellular fliuds become very dilute, this results in a decrease in osmolarity , therefore, water will then move into the intracellular fluid by osmosis in order to establish equilibrium.. This causes the cells to swell, and in the brain, this swelling will result in increase in pressure within the cranium. This increase in pressure leads to the symptoms found in water intoxication such as nausea, confusion, and fainting. If not treated, it can result in death.

From the given options;

A. Dilute body fluids is only a part of the cause

B. Osmosis of water from ICF to ECF does not result in water intoxication because in water intoxication, water moves into the ICF from ECF

C. Decrease in water intake is wrong because it is an increase in water intake that results in water intoxication

D. Decrease in the osmolarity of interstitial fluids is only one part of the cause of water intoxication

E. Dilute body fluids and a decrease in the osmolarity of interstitial fluids is the correct option.
