Respuesta: enfermedad de célula falciforme
Explicación: Para algunas condiciones, tener una copia mutada de un gen en cada célula es ventajoso, mientras que tener dos copias mutadas causa la enfermedad. El ejemplo mejor estudiado de este fenómeno es la enfermedad de células falciformes: tener dos copias mutadas del gen HBB en cada célula da como resultado la enfermedad, pero tener solo una copia proporciona cierta resistencia a la malaria. Esta resistencia a la enfermedad ayuda a explicar por qué las mutaciones que causan la enfermedad de células falciformes todavía se encuentran en muchas poblaciones, especialmente en áreas donde prevalece la malaria.
Answer:
These mutualistic relationships are typically characterized by benefits to both the fungi and the plant that host them, with both benefitting at the same time.
Explanation:
Mutualism relationships are often characterized by a beneficial relationship between organisms. If one party benefits and the other doesn't benefit or the other doesn't really need the relationship, then that is not a mutualistic one.
Fungi partner plants for mutual benefits where the plant benefits and also reward the fungi. Two ways are explained below:
1. Fungi that live within plant tissues, produce toxins that affect animals that feed on the plant so limiting grazing, this activity tends to make the plant not overgrazed and protects the plant tissues. In turn for this favor, the plant rewards the fungi with nutrients to aid their continuous survival.
2. Mycorrhiza is a type of fungi found in plant roots and they are fed with most especially carbohydrates. So as they grow in population and thrive well they also reward the plant with the capacity to take up more essential nutrients from the soil which is very important for plants productivity.
The test that will most likely be prescribed is an Ultrasound Examination.
Answer:
B) be able to be disproven
Explanation:
Scientific investigations involve the use of scientific methods, which is a principled guideline for scientific observations. One of the steps of the scientific method includes formulating an hypothesis, which is a predictive statement about the possible solution to an observed problem. This hypothesis is FALSIFIABLE i.e it must via experimentation/testing be proven to be false.
This qualifies a happening or phenomena as SCIENTIFIC. It must be able to be repeatedly tested for the purpose of disproven or falsifying the hypothetical claim.
