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
<span>worst thing that can happen in the modern environmentalism according to Jones is that how people treat will respond to you based on your color and status. People think that you are stupid because you are poor, that's why the amount of help that poor people receive if there's a disaster is very limited.

Answer:
Hey mate......
Explanation:
This is ur answer.....
1A) There are 2 ways:-
<em><u>•</u></em><em><u> </u></em><em><u>Anaerobic Respiration.</u></em>
<em>The anaerobic respiration process takes place in the absence of oxygen. </em>
<em><u>•</u></em><em><u> </u></em><em><u>Aerobic Respiration</u>. </em>
<em>In aerobic respiration, breakdown of pyruvate takes place in the presence of oxygen to give rise to 3 molecules of carbon dioxide and water.</em>
2A) <em>Oxygen is transported from lungs to body cells in the form of oxyhemoglobin . the main 2 gases exchanged are 02 & C02 . 02 is absorbed by blood capillaries from lungs alveoli by diffusion while C02 is absorbed by blood alveoli from blood capillaries by diffusion.</em>
Hope it helps!
mark me brainliest pls.....
Follow me! :)
There is obviously not a definite number because there are so many kinds of insects that we are not familiar with yet. However, approximate numbers mention as low as 2 million up to as high as 30 million. Scientists cannot still determine the correct number, but it is somewhere between 2 and 30 million species.
Carpet, meta carpel and phalanges
