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?
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.

Even though mitosis and meiosis produce cells for different purposes, there are similarities between the two processes. Which statement most accurately states how the two types of cell division are alike?
Group of answer choices
The daughter cells produced by both processes are haploid.
Homologous chromosomes cross over during the first prophase stage in both processes.
DNA replicates before mitotic prophase and prophase II.
Sister chromatids separate during anaphase II and mitotic anaphase.
Answer:
The daughter cells produced by both processes are haploid
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.

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.
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.

B)Fusion reactions do not produce harmful radiation and transuranium nuclides.
C)Fusion reactions can proceed in any temperature range.
D)Fusion reactions are easier to control and regulate.
Answer:
B)Fusion reactions do not produce harmful radiation and transuranium nuclides.
Explanation:
___________
The benefit of utilizing fusion reactions instead of fission reactions is that the fusion reaction does not produce harmful radiation and transuranium nuclides. Thus, the correct option for this question is B.
What is meant by Fusion?Fusion may be defined as a type of process that significantly involves the combination of two or more atoms or molecules in order to form one larger molecule. This type of reaction normally occurred in nature as compared to fission.
The process of fission involves the disintegration of numerous smaller molecules or atoms from a larger one. This creates a lot of long-lived radioactive substances in nature that are harmful to live organisms. These types of reactions are not favored by nature.
Therefore, fusion reactions do not produce harmful radiation and transuranium nuclides are the benefit of utilizing fusion reactions instead of fission reactions. Thus, the correct option for this question is B.
