Answer:

10000times higher H+ concentration

Relative to a solution with a pH of 7, a solution with a pH of 3 has of 10,000 times higher H+ concentration. Thus, the correct option is a.

The pH scale is a logarithmic scale that measures the concentration of hydrogen ions (H+) in a solution.

Each unit change in pH represents a tenfold change in H+ concentration.

Consider that each decrease in pH by 1 unit corresponds to a tenfold increase in H+ concentration.

So, going from pH 7 to pH 6 would mean a tenfold increase in H+ concentration, pH 5 would be a hundredfold increase, pH 4 would be a thousandfold increase, and pH 3 would be a ten thousandfold increase.

So, a solution with a pH of 3 has 10,000 times higher H+ concentration compared to a solution with a pH of 7.

Thus, the correct option is a.

She was not carrying an umbrella or rain jacket because the climate in her town was normally very hot and dry, the main factors that influence the amount of precipitation in an area or region is prevailing winds, presence of mountain ranges, seasonal winds​

Climate is defined as a long-term pattern of weather in a specific area. the change weather can occur from hour-to-hour, day-to-day, month-to-month or even year-to-year.

the determination of climate can be occurred by a region’s climate system, this system consist of major components such as the atmosphere, the hydrosphere, the cryosphere, the land surface, and the biosphere.

The atmosphere is the variable part of the climate system where the composition and movement of gases surrounding the Earth can change radically, influenced by natural and human-made factors.

Changes to the hydrosphere, which include variations in temperature and salinity, occur at much slower rates than changes to the atmosphere.

22

Explanation:

Humans have 22 pairs of autosomes. The human body has a total amount of 46 chromosomes. 22 autosomes and the 23rd pair is the sex chromosomes that determine someone's sex.

The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.  All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:

A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.

These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.

The reason why HIV is so diffucult to treat is because it is a virus (C).

HIV virus expands (multiplies itself) by using the bodie's inmmune system. The more the immune system tries to fight the virus the more the virus replicates.

Also HIV virus has a very high turnover making billions of copies each day and easily developes a drug resistance.

Answer:

it is c: glycolysis

Explanation:

its correct on edmentum

Glycolysis is a process of biochemical importance which receives a supply of NAD+ions from the fermentation process during anaerobic respiration. Therefore, option (C) is correct.

Glycolysis  occurs in both aerobic and anaerobic respiration and is a  metabolic process. During anaerobic respiration, glycolysis is the only process that produces ATP.

In the absence of oxygen, the electron transport chain cannot function, and therefore, the Krebs cycle and electron transport system are not active. Therefore, glycolysis is the correct answer.

Answer:

- La genética microbiana ha sido fundamental para la comprensión de diferentes mecanismo genéticos y evolutivos  

- Los microrganismos son ampliamente utilizados en medicina y procesos biotecnológicos  

- La microbiología ha permitido descartar la teoría de la generación espontanea (anteriormente aceptada en biologia) como así también formular nuevas teorías (hoy en día ampliamente aceptadas por la comunidad científica)

Explanation:

La genética microbiana juega un papel fundamental en biología, ya que los organismos microscópicos (por ejemplo, bacterias) poseen características únicas para el estudio de mecanismos genético/moleculares tales como, por ejemplo, 1-un corto tiempo generacional y 2-la capacidad de manipulación de un número de organismos muy alto (N muestral) en un laboratorio. En consecuencia, los microrganismos permiten estudiar mecanismos genéticos y evolutivos con mayor grado de precisión y versatilidad al ser comparados con organismos pluricelulares. La microbiología ha permitido el desarrollo de técnicas esenciales en el campo de la biología molecular: la técnica de edición genómica CRISPR-Cas9 se basa en el sistema adaptativo que poseen ciertas bacterias para hacer frente a infecciones virales. La biotecnología microbiana ha permitido también desarrollar diferentes tipos de alimentos y procesos biotecnológicos (por ejemplo, la cerveza y ciertos productos lácteos requiere la utilización de microrganismos para llevar a cabo el proceso de fermentación). Por otra parte, mediante técnicas de recombinación genética podemos explotar las características de los microrganismos para producir a gran escala ciertos productos biotecnológicos y medicinales (por ejemplo, producir insulina para uso humano). La microbiología emergió en la segunda mitad del siglo XIX y desde entonces ha posibilitado el desarrollo de importantes avances para el tratamiento y cura de enfermedades infecciosas, como así también descartar teorías tales como la generación espontánea y generar nuevos conocimientos en el campo de la biología y la genética (por ejemplo, el descubrimiento que el ADN se replica de manera semiconservativa fue realizado utilizando cepas de E. coli).

Welcome to the NASA Educational Exhibit! Today we'll be discussing Punnett squares and probability.

Genetics is the study of how traits are passed from parents to their offspring. Punnett squares are used to predict the probability of inheriting certain traits. For this exhibit, we've selected a pair of parents, one with straight hair and one with curly hair.

The genotypes of the parents are:

Straight hair parent: SS (homozygous dominant)

Curly hair parent: ss (homozygous recessive)

The phenotype of the parents are:

Straight hair parent: Straight hair

Curly hair parent: Curly hair

We selected this pair because they both have very different hair types, and hair type is a trait that is easy to see and identify.

Let's use a Punnett square to predict the possible offspring of these parents. The Punnett square below shows the possible combinations of alleles that could result from their mating .

As you can see from the Punnett square, there is a 50% chance that the offspring will have straight hair (genotype: Ss), and a 50% chance that the offspring will have curly hair (genotype: ss).

In summary, Punnett squares can help us predict the probability of inheriting certain traits. By understanding genetics and probability, we can learn more about the world around us and make informed decisions about breeding and genetic disorders.

*Oxygen is an essential element in the atmosphere that helps living organisms stay alive.

*Tress gives Earth oxygen through the process of photosynthesis. Plants, such as trees, capture sunlight and use it to split carbon dioxide and water. The product of it is sugar which releases oxygen into the atmosphere as a by-product of the process.

Answer:

The Factor that most affects drug absorption s the Lipid solubility of the drug            

Explanation:  

For a drug to accomplish its pharmacological function, it needs to suffer absorption mechanisms.

Most drugs, those that do not act locally, need to be correctly concentrated in their action sites or target sites. The first step is absorption.

This involves the obligated pass through the semipermeable plasmatic membrane to finally get in the blood. In blood, the drug moves, distributes, metabolizes, and the unaltered molecules are excreted.

There are different mechanisms in which drugs can cross the membrane that depends on the drug type. Depending on the effects of these mechanisms, there will be a more or less concentrated drug at the target sites.

Plants are photosynthetic. So, they prepare their own food by using raw materials from atmosphere like CO2, H2O and sun’s energy. CO2 is the carbon source for the synthesis of glucose through array of enzyme catalysed biochemical reactions taking place in chloroplast of plant cell.

Animals are heterotrophic in nutrition. So, they get energy; i.e. glucose from the food they eat. It depends on what is their food source. For example, herbivorous animals eat variety of plants, starch and cellulose of which become glucose source. Carnivorous animals eat other animals, whose stored glycogen or fat becomes energy source for them.
