The correct answer is A.The climate is changing rapidly but it will be too expensive to fix.
Explanation:
Climate change involves important long-term changes in climate patterns as well as other features on land and bodies of water. This phenomenon has occurred naturally during the history of Earth; however, nowadays climate change has accelerated due to human activities that produce global warming and therefore the increase in temperatures and changes in climate.
Despite this, some deny climate change, which is known as climate change denial; this includes stating climate change does not exist, it is an exaggeration or a hoax, or considering it is the result of natural cycles. According to this, the only statement that is not based on climate change denial is "The climate is changing rapidly but it will be too expensive to fix" because in this statement the speaker recognizes climate change is real and considers it is a serious issue that might be difficult to solve.
Answer:
Explanation:
La fecundación es el proceso por el cual dos gametos (masculino y femenino) se fusionan durante la reproducción sexual para crear un cigoto con un genoma derivado de ambos progenitores. Los dos fines principales de la fecundación son la combinación de genes derivados de ambos progenitores y la generación de un cigoto.
En el caso de las plantas con semillas pros, hay que diferenciar el fenómeno de la fecundación propiamente dicho (unión íntima de dos células sexuales hasta confundirse sus núcleos respectivos y, en mayor o menor grado, sus citoplasmas),1 del proceso biológico que lo antecede: la polinización, en el que los granos de polen, desarrollados en las tecas que contiene cada antera de un estambre (hoja reproductora masculina), son transportados por el viento o los insectos a los estigmas, donde germinan emitiendo un tubo polínico que crece hacia el ovario. En este caso no se trata de gametos, sino de esporas, pues cada grano de polen contiene dos gametos o células reproductoras masculinas
