Answer:
Las unidades de Mendel se conocen ahora como GENES
Explanation:
Durante sus experimentos, Mendel demostró que las características de las plantas de guisante (por ejemplo color de la flor, color de la semilla, forma de la semilla, altura de la planta, etcétera) eran heredadas, y denominó "elementos" a las unidades portadoras de dichas características. Es decir que cada elemento o unidad discreta, era el responsable de que la planta exprese una u otra característica. Estableció que estos elementos se redistribuían independientemente uno de otro, generación tras generación. Con el paso del tiempo y el avance de las investigaciones, estas unidades o elementos fueron denominados <em>Genes</em>.
To confirm the above hypothesis, Maria should perform an experiment to prove that xylem is responsible for the transport of coloured water through the plant. This is called the ascent of sap.
A suitable plant having a tender, semitransparent stem should be selected. The root system of the plant should be cut off and the twig has to be placed half-immersed in a coloured solution of water for about one hour. Later, when the plant is observed, parallely running streaks of coloured water can be seen through the semitransparent stem and other parts of the plant indicating that the xylem is involved in the upward movement of water.
Answer: Specie
Explanation:
The basic unit of classification of living things is species. species is the smallest unit containing members which have the largest number of features in common and usually interbreed among themselves.
Thus, the group of deer describes a specie since they can interbreed freely and are similar in characteristic features.
Answer:
d
Explanation:
Fishes are aquatic vertebrates having scales, pharyngeal gill slits and paired fins. ... Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary as ambient temperatures change. fishes have scales that covers the skin of fishes. Thus, the correct answer is option D.
