Answers

Answer 1

Answer:

The answer is B. base Have a great day!!!

Answer 2

The correct answers are:

1. Acid 2. Hydrogen ions 3. Hydroxide ions 4. The solution becomes neutral 5. base 6. acid.

The pH scale is the standard scale that specifies if an aqueous solution is acidic or alkaline/ basic. pH means the relative concentration of hydrogen ions, H+, and hydroxy OH- ions in the solution.

Lower pH values (0 - 7) exhibit more hydrogen ions which means the solution is acidic for instance Strawberry kool-aid add into the water strawberry kool-aid releases H+ ions in the solution.

Hence strawberry kool-aid is an acid.

Higher values in the pH scale (7-14) are an indicator for the alkaline or base solution, Alka-seltzer changes pH from 5.4 to 8.3 which means the solution concentration of OH- ions increases and the solution becomes basic.

Hence, the solution is basic and the Alka-seltzer gives hydroxy ions in the solution.  

    Given that baking soda is a strong base and hydrochloric acid is a strong acid, mixing both leads to salt and water as both have almost equal strengths of acid and base neutralization, therefore, the solution would be neutral or slightly acidicOn the basis of the given explanation, we can say that bleach is base as it has a pH value of 9.4 whereas coffee is acidic as pH value is 5.

Thus, the correct answer is - 1. Acid 2. Hydrogen ions 3. Hydroxide ions 4. The solution becomes neutral 5. base 6. acid.

Which of the following is true about groundwater?
A) Groundwater is the biggest fresh water reservoir on Earth.
B) When the rate of pumping is greater than the rate of infiltration, shallower wells may run dry.
C) There is more water stored in groundwater than in all Earth's lakes and rivers combined.
D) all of the above

Answers

Answer:

D. All of the above

Explanation:

Edge 2020

The following is true about groundwater: all the above is present in Option D because groundwater is present more than rivers and lakes combined and is the biggest reservoir on earth.

What is the ground water like?

The ground water is present in the earth and can be used for drinking, bathing, and other usable purposes, so out of all the water sources such as lakes and rivers, the ground water is higher in amount and can be reduced if wasted. If more pumping is done, then the ground water level will be reduced, and as a result, the swallow wells may run dry, so the ground water level will increase when it rains and the plants absorb the water into the soil.

Hence, the truth about groundwater is that all the above is present in Option D because groundwater is present more than rivers and lakes combined and is the biggest reservoir on earth.

Asi todas las células son muy pequeñas. ¿Qué limitaciones físicas y metabólicas determinan el tamaño celular? ¿ A qué problemas se enfrentaría una célula enorme? ¿Qué adaptaciones ayudarían a una célula muy grande a sobrevivir?

Answers

Answer:

- Limitación física: la relación superficie volumen es baja para un intercambio eficiente de sustancias con el medio

- Limitación metabólica: en principio no existen limitaciones metabólicas  

Explanation:

La membrana celular es una estructura fundamental para el funcionamiento celular, ya que de la membrana celular depende el intercambio de nutrientes y desechos por parte de la célula con su entorno (medio extracelular). En células muy grandes la relación entre la superficie cubierta por la membrana y el volumen celular es muy baja, lo cual dificulta el intercambio de compuestos (tanto nutrientes como desechos) con el medio extracelular. Por otro lado, los mecanismos metabólicos en principio no deberían verse afectados por el tamaño celular. Por ejemplo, los perfiles metabólicos de expresión génica son independientes del tamaño celular y están adaptados a diferentes tipos celulares, desde una célula huevo que es proporcionalmente varias veces más grande que un célula diferenciada la cual sin embargo no ha perdido la capacidad de dividirse, un ejemplo de esto son las células cancerosas derivadas de células epidérmicas diferenciadas las cuales poseen la capacidad de dividirse y de proliferar indiscriminadamente.

What is genetic diversity?

Genetic diversity refers to the variation in genes and inherited traits that exists within and among populations of organisms. This variation arises due to a number of factors, including mutations, genetic recombination, and genetic drift. Genetic diversity is an important aspect of biological diversity, as it can allow populations to adapt to changing environmental conditions and may enhance their overall fitness and survival.

Genetic diversity can occur at different levels, ranging from variation within individuals (such as somatic mutations) to variation among populations of the same or different species. It is important to maintain genetic diversity within populations and across species in order to preserve the overall health and viability of ecosystems.

The primary reason that osteoporosis accelerates after menopause in women is: * 2 points A. Increased osteoblast activity. B. Reduced levels of vitamin C. C. Diminished osteoclast activity. D. Reduced levels of circulating estrogens.

Answers

Answer:

The correct answer is D. Reduced levels of circulating estrogens.

Explanation:

Estrogens prevent the loss of calcium and ensure its proper mineralization, thus preventing the bones from becoming brittle, maintaining the consistency of the skeleton and preventing osteoporosis. Osteoporosis is a skeletal disease in which there is a decrease in bone mass density. Thus, the bones become more porous, the number and size of the cavities or cells that exist inside them increases, they are more fragile, they resist shocks worse and they break more easily. Menopause is the definitive cessation of ovarian function that, externally, results in the disappearance of the menses and usually occurs around 50 years (the interval goes from 45 to 55 years). It is the gradual loss of calcium in the bones, which accelerates in the first years of menopause due to estrogen deficiency. At the beginning of the disease, there are no symptoms and, as it progresses, there is a tendency to suffer fractures, which leads to a decrease in height.

Explanation:

The statement 'sister chromatids separate during anaphase II and mitotic anaphase' most accurately states how the two types of cell division are alike.

The sister chromatids are identical copies that form during the DNA replication of a chromosome.

Sister chromatids separate during Anaphase in mitosis to form two daughter cells.

Conversely, during meiosis, homologous chromosomes separate during Anaphase I, while sister chromatids separate during Anaphase II to form four haploid cells.

In conclusion, the statement 'sister chromatids separate during anaphase II and mitotic anaphase' most accurately states how the two types of cell division are alike.
