Answer:
Verdadero
Explanation:
Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.
Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.
Genotipo:
- Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)
- Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)
- Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)
Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.
Sin embargo, si tenemos los siguientes genotipos acompañando esta información:
- MM--> Amarillo
- Mm--> Amarillo
- mm --> Rojo
Recién ahora podemos deducir que el caracter dominante es el amarillo.
Answer:
What are stinkhorns? Stinkhorns are mushrooms that are found from the tropics to more temperate regions such as Wisconsin. They can suddenly appear in mulch, lawns, and areas with bare soil. These visually-shocking fungi get their common name from their characteristic, unpleasant odor. Although they are often unwanted additions to home gardens, stinkhorns do not cause plant disease. Because stinkhorns can grow on dead organic material, they actually are beneficial in that they contribute to the recycling of plant debris into nutrients that improve soil fertility and can be used by garden plants.
What do stinkhorns look like? Stinkhorns grow into various shapes, but they are bestknown for looking like horns or penises. A few species grow several appendages, resulting in an octopus-like appearance. Some species have a veil attached below the cap that resembles a lacey skirt flowing from the mushroom’s hollow stalk. Stinkhorns can range in color from white, beige, and olive to bright orange or red with black accents. The tips of mature stinkhorns are usually coated in a spore-containing slime. Gardeners often discover immature stinkhorns as they dig in the soil. The immature forms appear as whitish to pink or purple, egg-shaped masses. Stinkhorns develop rapidly sometimes growing up to four to six inches per hour, and can generate enough force to break through asphalt.
Where do stinkhorns come from? Stinkhorns are often first introduced into a garden in organic materials (e.g., soils and mulches) that contain microscopic hyphae (i.e., fungal threads) of stinkhorn fungi. Once stinkhorns mature, they produce a pungent, off-putting odor that is reminiscent of rotting flesh or dung. This smell may disgust people, but it attracts insects, particularly flies. Flies and other insects eat the slimy material at the tips of stinkhorns and carry spores in this slime to new locations as they move around in the environment. In many ways, this process is comparable to the distribution of pollen by bees (but of course without the more appealing scents associated with most flowers).
False. Probably I don’t have much context
The correct answers should be answer set 1.) Precipitation, water vapor, and icy debris. Hope this helped!
Answer:
C. release of neurotransmitters
Explanation:
The action potential is an explosion of electrical activity that is created by a depolarizing current. This means that some event (a stimulus) causes the resting potential to move toward 0 mV. When the depolarization reaches about -55 mV a neuron will fire an action potential.
