Answer:
It is a tool for keeping population in equilibrium state.
Explanation:
One female egret represents that she is a tool for the continuity of its breed or species because female egret lays eggs and reared their offspring in order to maintain its generation in that salt marsh area. These female egrets are the essential part of this salt marsh ecosystem due to the ability to control the population of other organisms through feeding behaviour. These female egrets helps in maintaining the equilibrium of the ecosystem by constantly producing baby egrets.
<h2>Answer:</h2>
Lysosomes are organelles that contain digestive enzymes (acid hydrolases). They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria. The membrane surrounding a lysosome prevents the digestive enzymes inside from destroying the cell.
As it turns out, our tears do contain some magic, namely the powerful enzyme lysozyme. This enzyme is crucial in thwarting bacteria that attempts to enter our body cavities. By destroying the peptidoglycan layer of bacterial cell walls, it serves as a strong chemical defense against bacterial infections.
Answer:
Después de la fecundación, la célula recién formada llamada cigoto lleva a cabo divisiones sucesivas hasta desarrollar un nuevo individuo. Estas divisiones se llevan a cabo mediante el proceso llamado<u> segmentación.</u>
Explanation:
Luego de que se produce la fecundación del óvulo y se forma el cigoto, los 3 a 4 días que le siguen abarca un proceso llamado <u>segmentación</u>. En este proceso se producen <u>sucesivas divisiones celulares</u> dando blastómeros, los cuales son células que forman el embrión y a las estructuras que este necesita para desarrollarse. La segmentación es un proceso que ocurre en las trompas de falopio mientras el cigoto se desplaza hacia el útero donde se implantará.
